Background For many reasons’ physiotherapists measure joint range of motion of their patients. There are usually variations in measurement values of each motion when measured either by the same person or by different observers. Also, reliability studies have resulted in varying levels of reliability coefficients. The purpose of this study was to compare the goniometric measurement reliability of a complex joint represented by the hip joint and a simple joint represented by proximal interphalangeal (PIP) flexion motions and to assess whether the two joint motions could be equally reliably measured by the same person under the same test and retest conditions. Method Thirty-three healthy subjects between the ages of 23 and 34 years participated. In order to assess the repeatability of measurements in the two selected joint motions, the r. level of each joint measurement was determined and their goniometric measurement reliability compared. Result Results were based on data collected by measuring the flexion range of motion of right hips and right middle finger PIP joints in normal adults. Statistical analyses indicated that there were significant differences between goniometric measurement reliability in hip and PIP flexion motions. Conclusion Two joints were goniometrically measured by the same tester under the same test condition. Reliability measurements results were compared in thirty-three adults. Based on the study, the researcher concluded that the goniometric measurement of hip flexion motion is more variable than that of PIP flexion motion.

To design and manufacture better artificial joints, it is necessary to obtain the motion range of lower limb statistically. General Staircase as an experimental device had been designed; motion capture system and plantar force measurement system were used to establish a systematic measurement method during stairs descent. The variation and range of hip, knee and ankle joints of 40 samples along different directions in a cycle have been calculated. During stair decent, motion range of hip, knee and ankle joints reach maximum in the sagittal plane and are larger comparing to joint motion range in walking and jogging.

Full textAbstract:
Six-revolute-joint instrumented spatial linkages (6R ISLs) have become often-used devices to measure the complete six-degree-of-freedom motion of anatomical joints. Accuracy of motion measurement depends on ISL design and calibration technique. In this paper, a design process is outlined that uses computer graphics and numerical methods as aids in developing 6R ISLs that (i) physically assemble within the desired range of motion of the joint; (ii) do not collide with either the experimental apparatus or the subject joint; (iii) avoid singular linkage configurations that can cause forces to be applied to the joint; and (iv) measure selected anatomical motions most accurately. It is found that a certain subgroup of 6R linkages are suitable for accurate measurement of specific motions, and can be the basis for new ISL designs. General guidelines are developed that can assist in the generation of unique linkage designs for different anatomical joints. The design process is demonstrated in the creation of an ISL to measure knee motion.

Background: Range of motion (ROM) measurements of the fingers are frequently obtained during hand physical examinations. While traditionally measured by manual goniometry, smartphone photography introduces an alternative method of ROM measurement that also has potential telemedicine applications. The purpose of this study was to evaluate the reliability of smartphone photography measurements as an alternative to traditional goniometry, using the patient with Dupuytren disease as a model. Methods: Patients with a confirmed Dupuytren contracture were prospectively enrolled in this study. Range of motion measurements of the affected joints were obtained prior to any invasive treatments. Two sets of photographs were taken by both a clinical staff member and a nonclinical individual unaffiliated with the study. Both sets of photos were analyzed for degree of contracture via software analysis and compared against traditional goniometer measurements. Results: The study prospectively enrolled 50 consecutive patients with Dupuytren disease, comprising 123 affected joints. The mean contractures of all affected joints as measured by manual goniometry, trained photograph goniometry, and untrained photograph goniometry were 38.5, 35.3, and 35.5, respectively. The mean difference in contracture measurement was 3.2° between manual and trained photograph goniometry and 3.0° between manual and untrained photograph goniometry. There was no statistically significant difference between trained and untrained photo set measurements. Photograph measurements between separate raters demonstrated high consistency (intraclass correlation coefficient = 0.92). Conclusions: Smartphone photography provides contracture measurements equivalent to the accepted error of a finger goniometer (3.2° compared with 5°). The accuracy of smartphone photography in measuring contractures offers potential telemedicine applications for both clinical and research needs.

The purpose of this study was to measure the functional range of motion of the finger joints needed to perform activities of daily living. Using the Sollerman hand grip function test, 20 activities were assessed in ten volunteers. The active and passive range of motion was measured with a computerized electric goniometer. The position of each finger joint was evaluated in the pre-grasp and grasp positions. The functional range of motion was defined as the range required to perform 90% of the activities, utilizing the pre-grasp and grasp measurements. The functional range of motion was 19°–71°, 23°–87°, and 10°–64° at the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints, respectively. This represents 48%, 59%, and 60% of the active motion of these joints, respectively. There was a significant difference in the functional range of motion between the joints of the fingers, with the ulnar digits having greater active and functional range. The functional range of motion is important for directing indications for surgery and rehabilitation, and assessing outcome of treatment.

ABSTRACTBackground : Joint flexibility decreases in old age due to a degenerative process resulting in changes in joints, connective tissue and cartilage in the elderly. Decreasing flexibility is also due to reduced elasticity of muscle fibers, where connective tissue in muscle fibers increases (Mariyam, 2008).Objective : The aim of this study was to analyze the effect of active exercise (ROM) on the lower extremities on increasing the flexibility of the knee joint in the elderlyMethods : This study using a quasi-experimental approach with One group pre-test and post-test design. The sampling technique uses the Slovin method of 42 people, obtained a sample of 25 elderly. Exercise is done twice a day for 8 days. Measurements were made on day 1, day 4 and day 8 of the study using a Goniometer measuring instrument..Result : The results of measurement I average of the right knee joint 117.52o, measurement II = 122.24, measurement III = 126, 36o. From the analysis with Paired simple t-Test between the measurements I and II, it was found that the different test measurements I and II t count value was equal to -1.908 with 0.068. Because sig 0.05, it can be concluded that Ho is accepted, meaning that the average angle of ROM before and after training is the same (not different). In the different test measurements II and III the value of t count is equal to -2.152 with sig 0.042.Conclusion : Because sig 0.05, it can be concluded that Ho is rejected, meaning that there is a difference in ROM angle after training between days 4 to 8 with the first day to day 4. Thus it can be stated that active ROM exercises affect the angle of ROM of the knee joint elderly after exercise ROM between day 4 to day 8. Keywords: active ROM exercise, flexibility of knee joint, elderly.

Background and Objectives: Within the clinical evaluation of multiple pathologies of the lower limb, the measurement of range of motion (ROM) of its joints is fundamental. To this end, there are various tools, from the goniometer as a reference to more recent devices such as inclinometry-based applications, photo capture applications, or motion capture systems. This study aimed to assess the validity, intra-rater, and inter-rater reliability of the VeloFlex system (VS), which is a new camera-based tool designed for tracking joint trajectories and measuring joint ROM. Materials and Methods: Thirty-five healthy volunteers (16 females; aged 18–61 years) participated in this study. All participants were assessed on two separate occasions, one week apart. During the first assessment session, measurements were obtained using a goniometer and the VS, whereas, in the second session, only the VS was used. In each assessment session, nine active movements were examined. For each movement, three trials were tested, and the mean of these three measures was used for analysis. To evaluate the concurrent validity and agreement, the Pearson correlation coefficient (r) and Bland-Altmann plots were used. Intra-rater and inter-rater reliability were evaluated using intra-class correlation (ICC), standard error of measurement (SEM), and minimal detectable change (MDC). Results: Both devices showed excellent correlations for all movements (r ranged from 0.992 to 0.999). The intra-rater reliability of the VS was excellent (ICC ranged from 0.93 to 0.99), SEMs ranged from 0.53% to 2.61% and the MDC ranged from 0.68° to 3.26°. The inter-rater reliability of the VS was also excellent (ICC ranged from 0.88 to 0.98), SEMs ranged from 0.81% to 4.76% and the MDC ranged from 2.27° to 4.42°. Conclusions: The VS is a valid and reliable tool for the measurement of ROM of lower limb joints in healthy subjects.

Range of motion measurement is fundamental in the physical examination and functional evaluation of different joints. WIMUTM is an inertial device that allows the analysis of joint motion easily in real time. This study had a two-fold goal: (i) to evaluate the validity of WIMUTM on the measurement of different angle positions, compared with a standard goniometer and 2D video-based motion analysis software; and (ii) to evaluate the use of WIMUTM in the assessment of angulations in a joint, specifically assessing the validity and reliability of WIMUTM on the measurement of ankle dorsiflexion, compared to a standard goniometer and Kinovea. The intraclass correlation coefficient and Pearson´s correlation coefficient (r) were performed to calculate the concurrent validity, and Bland-Altman plots were performed to analyze agreement between measures. For the analysis of reliability, both relative and absolute indices were used. The results showed excellent validity and reliability of WIMUTM in the assessment of angle positions and ankle dorsiflexion. The current findings conclude that WIMUTM is a valid and reliable instrument to measure angle and joint motions. In short, WIMUTM provides a new clinical and sportive method of angle measurement.

<p>The methods used to quantify finger range of motion significantly influence how hand disability is reported. To date, the accuracy of sensors being utilized in data gloves from the literature has been ascertained yet need further analysis. This paper presents an inertial measurement unit sensor-based data glove for finger joint measurement developed for collecting a range of motion data of distal interphalangeal, proximal interphalangeal and metacarpophalangeal finger joints of an index finger. In this study, three inertial measurement sensors, MPU-6050 and two flexible bend sensors which are capable to detect angle displacement were attached to the distal interphalangeal, proximal interphalangeal and metacarpophalangeal finger joint points on the glove. The data taken from inertial measurement unit sensors and flexible bend sensors were acquired using Arduino and MATLAB software interface. The data obtained were compared with the reference data measured from goniometer to allow for accurate comparative measurement. The percentage of error resulted from MPU-6050 sensor unit were ranged from 0.81 % to 5.41 % were very low which indicates high accuracy when compared with the measurements obtained using goniometer. On the other hand, flexible bend sensor shows low accuracy (11.11 % to 19.35 % error). In conclusion, the inertial measurement unit sensor-based data glove using MPU-6050 sensors can be a reliable solution for tracking the progress of finger rehabilitation exercises. In order to motivate patients to adhere to the therapy exercises, interactive rehabilitation game will be developed in the future incorporating MPU-6050 sensors on all five fingers.</p>

Full textAbstract:
This study involves measurements of bi-axial ankle stiffness in older adults, where the ankle joint is passively moved along the talocrural and subtalar joints using a custom ankle movement trainer. A total of 15 elderly individuals participated in test–retest reliability measurements of bi-axial ankle stiffness at exactly one-week intervals for validation of the angular displacement in the device. The ankle’s range of motion was also compared, along with its stiffness. The kinematic measurements significantly corresponded to results from a marker-based motion capture system (dorsi-/plantar flexion: r = 0.996; inversion/eversion: r = 0.985). Bi-axial ankle stiffness measurements showed significant intra-class correlations (ICCs) between the two visits for all ankle movements at slower (2.14°/s, ICC = 0.712) and faster (9.77°/s, ICC = 0.879) speeds. Stiffness measurements along the talocrural joint were thus shown to have significant negative correlation with active ankle range of motion (r = −0.631, p = 0.012). The ankle movement trainer, based on anatomical characteristics, was thus used to demonstrate valid and reliable bi-axial ankle stiffness measurements for movements along the talocrural and subtalar joint axes. Reliable measurements of ankle stiffness may help clinicians and researchers when designing and fabricating ankle-foot orthosis for people with upper-motor neuron disorders, such as stroke.

Fifteen fresh-frozen cadaveric lower extremities were studied to evaluate the reliability of measuring subtalar motion using a bubble inclinometer. There was high intra-observer reliability for manual inversion and eversion of the subtalar joint with the tibiotalar joint locked and unlocked. Poor correlation of radiographic and clinical measurements questioned the validity of bubble inclinometer measurements. The contribution of the tibiotalar joint to apparent subtalar motion, as measured clinically and radiographically, was found to be one-third of the arc of motion, as compared to motion measured clinically and radiographically with the tibiotalar joint locked.

Background. The measurement of the functional range of motion (FROM) of lower limb joints is an essential parameter for gait analysis especially in evaluating rehabilitation programs.Aim. To develop a simple, reliable, and affordable mechanical goniometer (MGR) for gait analysis, with six-degree freedom to dynamically assess lower limb joint angles.Design. Randomized control trials, in which a new MGR was developed for the measurements of FROM of lower limb joints.Setting. Reliability of the designed MGR was evaluated and validated by a motion analysis system (MAS).Population. Thirty healthy subjects participated in this study.Methods. Reliability and validity of the new MGR were tested by intraclass correlation coefficient (ICC), Bland-Altman plots, and linear correlation analysis.Results. The MGR has good inter- and intrarater reliability and validity withICC≥0.93(for both). Moreover, measurements made by MGR and MAS were comparable and repeatable with each other, as confirmed by Bland-Altman plots. Furthermore, a very high degree of linear correlation (R≥0.92for all joint angle measurements) was found between the lower limb joint angles measured by MGR and MAS.Conclusion. A simple, reliable, and affordable MGR has been designed and developed to aid clinical assessment and treatment evaluation of gait disorders.

Background: No goniometric technique is both maximally convenient and completely accurate, although photogoniometry (ie, picture taking to facilitate digital angle measurement) shows promise in this regard. Our purpose was to test the feasibility and reliability of a photogoniometric protocol designed to measure wrist and digit range of motion in general. Methods: Two independent observers examined a sample of joints in both normal and abnormal hands according to a photogoniometric protocol. Interrater and intrarater correlation were calculated, and these measurements were compared with measurements made by a third independent examiner with a manual goniometer. Results: The photo-based measurements were reliable within and between observers; however, only a minority of these measurements were in agreement with manually collected values. Conclusions: At present, photogoniometry is not an acceptable alternative to manual goniometry for determining wrist and digit range of motion in general. Joint-specific photogoniometry should be the subject of future study, as should relevant imaging and software technology.

Object The authors measured the range of motion (ROM) of the spine in healthy individuals by using an electromagnetic tracking device to evaluate the functional performance of the spine. Methods The authors used the Flock of Birds electromagnetic tracking device with 4 receiver units attached to C-7, T-12, S-1, and the midthigh region. Forward/backward bending, bilateral side bending, and axial rotation of the trunk were performed in 18 healthy individuals. Results The average ROM was calculated after 3 consecutive measurements. The thoracic spine generated the greatest angle in axial rotation and smallest angle in backward bending. The lumbar spine generated the greatest angle in forward bending and smallest angle in axial rotation. The hip joints generated the greatest angle in forward bending and smallest angle in backward bending. Additionally, 40% of forward-bending motion occurred in the lumbar spine and 40% occurred in the hip joints. Approximately 60% of backward bending occurred in the lumbar spine; 60% of axial rotation occurred in the thoracic spine; and 45% of side bending occurred in the thoracic spine. Conclusions The Flock of Birds electromagnetic tracking device cannot only measure the ROM of spine but also easily differentiate the 6-degree contributions by different segments.

Concavity-compression is an important mechanism for keeping a joint centered despite a large range of motion. The purpose of this study was to explain how the results of a test measuring the joint intrinsic stability can be interpreted and related to joint architecture. As an example, the method was demonstrated for the glenohumeral joint although the versatility allows any articulating joint, whether natural or prosthetic, to be analyzed. The initial slope from the central point was relatively steep, indicating a large resistance to translation. The peak translation force occurred within the first 5 mm of displacement for the glenohumeral joint, indicating a high congruence between the humerus and glenoid surfaces. Stability ratio, calculated as the maximum translation force divided by the applied joint compressive force, makes it possible to compare the stabilizing effect under different compressive loads for different anatomical directions. In hanging arm position, the joint stability ratio ranged from 30.5% to 60.1%. Finally, the effective depth of the concavity and the maximum range of joint translation can be measured by completely dislocating the joint. For the glenohumeral specimen, the smallest glenoid concavity depth, 3.8 mm, occurred in the anterior direction. The joint translation limit was smallest in the anterior-posterior direction (28.0 mm). The methodology presented in this study will allow consistent testing parameters between different trials, easily allowing parametric studies to gain a more complete understanding of articular joints.

In clinical settings, available valid and reliable tools are important components in evaluating the lower extremity range of motion. Although the digital inclinometer is highly reliable compared to the universal goniometer, its availability and high cost impede its extensive use. Nowadays, smartphone applications have become widely available to clinicians for assessing the joint range of motion. The present study aims to assess the validity and intra-rater reliability of the smart- phone application “Clinometer” for measuring hip, knee, and ankle sagittal ranges of motion, using the digital inclinom- eter as the reference standard. Active hip, knee flexion and ankle dorsiflexion and plantarflexion range-of-motion mea- surements were recorded in 102 young, healthy female participants on two separate occasions using Clinometer and a digital inclinometer. Pearson’s correlation coefficients (r) were used to evaluate the smartphone application’s validity against the digital inclinometer. To assess the reliability of the Clinometer app, the intra-class correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable difference (MDD) were used. Clinometer displayed excellent validity when compared to the digital inclinometer for hip and knee movements (r>0.90), while ankle ROM displayed moderate validity (r = 0.52-0.57). Additionally, Clinometer demonstrated excellent reliability (ICC > 0.90) for hip and knee sagittal plane motion and moderate reliability for the ankle sagittal plane motion (ICC = 0.53–0.67). Cli- nometer is a portable, low-cost, valid, and reliable tool for assessing active hip and knee range of motions and can be easily incorporated into clinical settings; however, it cannot be used interchangeably for ankle measures.

Full textAbstract:
ABSTRACT Standard goniometry is the most commonly used method of assessing the range of motion (ROM) in patients with burn scar contracture. However, standard goniometry was founded on arthrokinematic principles and doesn’t consider the cutaneous biomechanical influence between adjacent joint positions and skin pliability to accommodate motion. Therefore, the use of standard goniometry to measure burn scar contracture is called into question. This prospective, multicenter, comparative study investigated the difference between standard goniometry, based on arthrokinematics and a revised goniometry protocol, based on principles of cutaneokinematics and functional positions to measure ROM outcome in burn survivors. Data were collected for 174 joints from 66 subjects at seven burn centers totaling 1044 measurements for comparison. ROM findings using the revised protocol demonstrated significantly more limitation in motion 38.8 ± 15.2% than the standard protocol 32.1 ± 13.4% (p < .0001). Individual analyses of the motions likewise showed significantly more limitation with revised goniometry compared with standard goniometry for 9/11 joint motions. Pearson’s correlation showed a significant positive correlation between the percentage of cutaneous functional units scarred and ROM outcome for the revised protocol (R2 = .05, p = .0008) and the Δ between the revised and standard protocols (R2 = .04, p = .0025) but no correlation was found with the standard goniometric protocol (R2 = .015, p = .065). The results of this study support the hypothesis that standard goniometry underestimates the ROM impairment for individuals whose motion is limited by burn scars. Having measurement methods that consider the unique characteristics of skin impairment and the impact on functional positions is an important priority for both clinical reporting and future research in burn rehabilitation.

AbstractGaited horse research is limited, with the majority of the research focusing on the measurement of the temporal variables of adult-gaited horses. The objective was to measure the fore and hind limb kinematics of the flat-walking Tennessee Walking Horse (TWH) yearling. Four TWH yearlings were filmed at 60 Hz being led at a consistent flat walk that followed breed standards. Reflective markers attached along palpation points of the joint centres of the fore and hind limbs were tracked for five strides for each yearling. During stance, the elbow (154±3°), carpal (185±3°), fore (222±9 and 221±9°) and hind fetlocks (216±11°), hip (111±3°), stifle (157±4°) and tarsal (167±9°) joints demonstrated peak extension with the forelimb fetlock joint having double peaks of extension. During swing, the same joints demonstrated peak flexion with the elbow (109±3°) and hip (88±6°) peak flexion occurring later in the swing phase. The carpal (54±4°) joint demonstrated a greater range of motion than the tarsus (40±9°) with less vertical displacement. The hind fetlock (60±10°) had greater range of joint motion compared with the forelimb fetlock (45±8°), but lacked the double peak of extension during swing. Kinematic measurements will assist in objectively defining the gait for both clinical and performance applications.

Background Goniometric measurements of hemiplegic arm joints must be reliable to draw proper clinical and scientific conclusions. Previous reliability studies were cross-sectional and based on small samples. Knowledge about the contributions of sources of variation to these measurement results is lacking. Objective The aims of this study were to determine the interobserver reliability of measurements of passive range of motion (PROM) over time, explore sources of variation associated with these measurement results, and generate smallest detectable differences for clinical decision making. Design This investigation was a measurement-focused study with a longitudinal design, nested within a 2-arm randomized controlled trial. Methods Two trained physical therapists assessed 7 arm movements at baseline and after 4, 8, and 20 weeks in 48 people with subacute stroke using a standardized protocol. One physical therapist performed the passive movement, and the other read the hydrogoniometer. The therapists then switched roles. The relative contributions of several sources of variation to error variance were explored with analysis of variance. Results Interobserver reliability coefficients ranged from .89 to .97. The PROM measurements were influenced by error variance ranging from 31% to 50%. The participant × time interaction made the largest contribution to error variance, ranging from 59% to 81%. Smallest detectable differences were 6 to 22 degrees and were largest for shoulder movements. Limitations Verification of shoulder pain and hypertonia as sources of error variance led to a substantial number of unstable variance components, necessitating a simpler analysis. Conclusions The assessment of PROM with a standardized protocol, a hydrogoniometer, and 2 trained physical therapists yielded high interobserver reliability indexes for all arm movements. Error variance made a large contribution to the variation in measurement results. The resulting smallest detectable differences can be used to interpret future hemiplegic arm PROM measurements with more confidence.

Background: Clinical measurement of passive dorsiflexion of the ankle joint is essential for the diagnosis of various pathologic conditions of the foot and ankle but is of unreliable precision with high interobserver variability in nonweightbearing tests. This work was designed to develop and test a precise, standardized, and reliable technique for measurement of passive and active ankle range of motion. Methods: The proposed measurement tool is composed of two mobile parallelograms, one attached to the tibia, the second one to the plantar surface of the foot. The parallelograms are connected with a hinge with an angular scale to measure the angle between the foot and tibia. Results: Interobserver correlation between clinical measure-ments for maximal passive foot dorsiflexion were 0.03 with knee extension and 0.38 with knee flexion, while for measurements with the proposed tool they reached 0.89 and 0.97, respectively, with a mean measurement error of 0.9 degrees. Intraobserver correlations reached values of r = 0.98 and 0.99. Conclusions: The proposed tool allows measurement of the ankle range of motion with very high precision and reproducibility far superior to clinical measurements. Clinical Relevance: Precise measurement of ankle range of motion is clinically challenging. With the use of the proposed tool, measurement precision and reliability are decisively improved.

Abstract Objectives The objective of this study was to assess the effectiveness of application of Kinesiology Taping for musculoskeletal system disorders in dancers, in comparison with the standard physiotherapy procedures. Design Cross-sectional study. Methods Examined were 77 dancers of the Dance Theater from Poland, both male and female (58 women and 19 men), 18–25 years old (M=20.03, SD=2.67), who experienced pain in musculoskeletal system and who specialized in jazz dancing. All the examined patients had undergone a three weeks long therapy. In the test group (N=52), Kinesiology Taping was applied to the selected groups of muscles, peripheral joints and spine, with the tapes being replaced 3 times, after each 7 days of therapy. In the control group (N=25), the standard physiotherapy procedures were applied. For the assessment of effectiveness of the therapies, there were used: interviews, measurement of pelvic static, measurement of muscle strength with a dynamometer, measurement of hip joint range of motion with a digital inclinometer and measurement of pain with VAS. Results Kinesiology Taping application has brought significant improvements in recovering proper pelvic static, increasing muscle strength, extending active range of motion of hip joints and lowering level of subjective sensation of pain. Conclusions Effectiveness of the Kinesiology Taping application for musculoskeletal system disorders in dancers is comparable with the standard physiotherapy procedures, which makes it possible to obtain a similar therapeutic effect, using the painless, well accepted by patients method of treatment, which is addition costs less.

Abstract Accurate measurement of hip motion is important in initial diagnosis, assessing progression over time, evaluating treatment outcomes, and rating impairments of this joint. In the AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition, range-of-motion (ROM) measurements are still a factor because the physical examination and other adjustment tables are used to select the grade and final rating. Further, ROM deficits may be used to derive a stand-alone rating when other tables refer the rater to motion impairment or if no diagnosis-based section is applicable for impairment rating. Hip motions generally are measured using a large goniometer, although an electronic inclinometer also may be used. Examiners must conduct tests in accordance with measurement instructions in the AMA Guides. From the standpoint of impairment rating, hip extension, at least beyond neutral, is irrelevant; if a patient does not have a flexion contracture of at least 10°, there is no extension impairment. Examiners should compare both extremities; active or voluntary motion is performed by the active contraction of the governing muscles and should be evaluated first. During this and other measurements, patients may have a tendency to extend or guard, thus producing an erroneously inflated measurement. Examiners must ensure that such behaviors do not occur and should record only the correct measurement.

Full textAbstract:
The purpose of this study was to develop a motion analysis protocol that allows the simultaneous assessment of all hand and finger joint movements. The objective was to demonstrate repeatability for future clinical applications in functional assessments. This study includes selection of marker positions, movement tasks, kinematic approaches and a comparison of the two most commonly used finger marker sets. By using a test–retest measurement of the range of motion in twenty healthy volunteers, the repeatability of the developed protocol was validated. Estimated errors of the presented method ranged from 1.2° to 6.4°. Finger joint angles derived from the marker set with two markers per segment showed better repeatability (3.7°) than with markers located on the joints (5.1°). Given the high repeatability found, the presented method appears to be suitable for clinical applications. For the fingers, measurement repeatability can be improved by using at least two markers per segment. Within this study, advanced kinematic approaches, such as functional determination of joint centers and axes, are applied to the analysis of hand movements. The provided standard values and estimate of the minimal detectable differences provide a valuable basis for meaningful data interpretation and may be used for future comparison with other protocols.

Full textAbstract:
Joint injuries during sporting activities might be reduced by understanding the extent of the dynamic motion of joints prone to injury during maneuvers performed in the field. Because instrumented spatial linkages (ISLs) have been widely used to measure joint motion, it would be useful to extend the functionality of an ISL to measure joint motion in a dynamic environment. The objectives of the work reported by this paper were to (i) design and construct an ISL that will measure dynamic joint motion in a field environment, (ii) calibrate the ISL and quantify its static measurement error, (iii) quantify dynamic measurement error due to external acceleration, and (iv) measure ankle joint complex rotation during snowboarding maneuvers performed on a snow slope. An “elbow-type” ISL was designed to measure ankle joint complex rotation throughout its range (±30deg for flexion/extension, ±15deg for internal/external rotation, and ±15deg for inversion/eversion). The ISL was calibrated with a custom six degree-of-freedom calibration device generally useful for calibrating ISLs, and static measurement errors of the ISL also were evaluated. Root-mean-squared errors (RMSEs) were 0.59deg for orientation (1.7% full scale) and 1.00mm for position (1.7% full scale). A custom dynamic fixture allowed external accelerations (5g, 0-50Hz) to be applied to the ISL in each of three linear directions. Maximum measurement deviations due to external acceleration were 0.05deg in orientation and 0.10mm in position, which were negligible in comparison to the static errors. The full functionality of the ISL for measuring joint motion in a field environment was demonstrated by measuring rotations of the ankle joint complex during snowboarding maneuvers performed on a snow slope.

Full textAbstract:
The purpose of this study was to investigate the functional relationships between selected ranges of motion of the neck, upper and lower limbs, the strength of the neck and trunk muscles, postural parameters, and the motor function of children with SMA1 and SMA2—27 children, aged 6 months-15 years, with genetically confirmed spinal muscular atrophy type 1 (19 children) and 2 (8 children) undergoing pharmacological treatment. All children were examined, according to the methodology, including the motor function evaluation, measurement of selected ranges of motion, assessment of postural parameters, and measurement of neck and trunk muscle strength. The functional status of 15 children was assessed with the CHOP INTEND (CHOP group) scale and of 12 children with the HFMSE (HFMSE group). The results obtained showed that, in children examined with the CHOP scale, greater limitation of flexion in the shoulder joints was observed. As the deformation of the chest increased, the functional abilities of children deteriorated. In participants examined with the CHOP group, the ranges of neck rotation decreased with the increase of the chest deformity. In the HFMSE group, the ranges of head rotation showed a strong relationship with some parameters of muscle strength and the sum of the R coefficients. Participants showed many significant relationships between the range of motion in the neck and joints of the limbs, with more significant relationships in the CHOP group. The following conclusions were made: motor skills of children with SMA depend on muscle strength, range of motion, and deformities of the spine and chest; the development of scoliosis adversely affects the motor function, ranges of motion, and muscle strength; and movement ranges are related to motor skills and strength values.

Full textAbstract:
Background. Robotic locomotion rehabilitation systems have been used for gait training in patients who have had a stroke. Most commercialized systems allow patients to perform simple exercises such as balancing or level walking, but an additional function such as stair-walk training is required to provide a wide range of recovery cycle rehabilitation. In this study, we analyzed stair-gait patterns and applied the result to a robotic rehabilitation system that can provide a vertical motion of footplates. Methods. To obtain applicable data for the robotic system with vertically movable footplates, stair-walk action was measured using an optical marker-based motion capture system. The spatial position data of joints during stair walking was obtained from six healthy adults who participated in the experiment. The measured marker data were converted into joint kinematic data by using an algorithm that included resampling and normalization. The spatial position data are represented as angular trajectories and the relative displacement of each joint on the anatomical sagittal plane and movements of hip joints on the anatomical transverse plane. Results. The average range of motion (ROM) of each joint was estimated as (−6.75°,48.69°) at the hip, 8.20°,93.78° at the knee, and −17.78°,11.75° at the ankle during ascent and as 6.41°,31.67° at the hip, 7.38°,91.93° at the knee, and −24.89°,24.18° at the ankle during descent. Additionally, we attempted to create a more natural stair-gait pattern by analyzing the movement of the hip on the anatomical transverse plane. The hip movements were estimated to within ±1.57 cm and ±2.00 cm for hip translation and to within ±2.52° and ±2.70° for hip rotation during stair ascent and stair descent, respectively. Conclusions. Based on the results, standard patterns of stair ascent and stair descent were derived and applied to a lower-limb rehabilitation robot with vertically movable footplates. The relative trajectory from the experiment ascertained that the function of stair walking in the robotic system properly worked within a normal ROM.

Full textAbstract:
This study aims to compare a new inertial measurement unit based system with the highly accurate but complex laboratory gold standard, an optoelectronic motion capture system. Inertial measurement units are sensors based on accelerometers, gyroscopes, and/or magnetometers. Ten healthy subjects were recorded while performing flexion-extension and radial-ulnar deviation movements of their right wrist using inertial sensors and skin markers. Maximum range of motion during these trials and mean absolute difference between the systems were calculated. A difference of 10° ± 5° for flexion-extension and 2° ± 1° for radial-ulnar deviation was found between the two systems with absolute range of motion values of 126° and 50° in the respective axes. A Wilcoxon rank sum test resulted in a no statistical differences between the systems with p-values of 0.24 and 0.62. The observed results are even more precise than reports from previous studies, where differences between 14° and 27° for flexion-extension and differences between 6° and 17° for radial-ulnar deviation were found. Effortless and fast applicability, good precision, and low inter-observer variability make inertial measurement unit based systems applicable to clinical settings.

Full textAbstract:
Twenty-one consecutive rheumatoid patients (23 hands, 92 joints) who underwent Silastic metacarpophalangeal joint arthroplasty between 1989 and 1993 had the 33-task Baltimore quantitative upper extremity function test prior to surgery and then repeated at intervals from 6 weeks to 1 year for all 23 hands and 3 to 4 years for 14 of the hands. In addition all hands had goniometer measurement of active range of finger joint motion and ulnar drift at each assessment. The average preoperative score was 71 improving rapidly to 89 at 6 weeks, to 91 at 1 year and 92 at 3 to 4 years. Most improvement occurred in functions requiring pinch span or hook grip and could be attributed largely to correction of ulnar drift and the change of metacarpophalangeal arc of motion. These results confirm that the Silastic metacarpophalangeal joint arthroplasty significantly improves hand function and that the improvement is maintained over a 3- to 4-year period.

Full textAbstract:
Background.Hand function is essential to a person’s self-efficacy and greatly affects quality of life. Adapted utensils with handles of increased diameters have historically been used to assist individuals with arthritis or other hand disabilities for feeding, and other related activities of daily living. To date, minimal research has examined the biomechanical effects of modified handles, or quantified the differences in ranges of motion (ROM) when using a standard versus a modified handle. The aim of this study was to quantify the ranges of motion (ROM) required for a healthy hand to use different adaptive spoons with electrogoniometry for the purpose of understanding the physiologic advantages that adapted spoons may provide patients with limited ROM.Methods.Hand measurements included the distal interphalangeal joint (DIP), proximal interphalangeal joint (PIP), and metacarpophalangeal joint (MCP) for each finger and the interphalangeal (IP) and MCP joint for the thumb. Participants were 34 females age 18–30 (mean age 20.38 ± 1.67) with no previous hand injuries or abnormalities. Participants grasped spoons with standard handles, and spoons with handle diameters of 3.18 cm (1.25 inch), and 4.45 cm (1.75 inch). ROM measurements were obtained with an electrogoniometer to record the angle at each joint for each of the spoon handle sizes.Results.A 3 × 3 × 4 repeated measures ANOVA (Spoon handle size by Joint by Finger) found main effects on ROM of Joint (F(2, 33) = 318.68, Partialη2= .95,p< .001), Spoon handle size (F(2, 33) = 598.73, Partialη2= .97,p< .001), and Finger (F(3, 32) = 163.83, Partialη2= .94,p< .001). As the spoon handle diameter size increased, the range of motion utilized to grasp the spoon handle decreased in all joints and all fingers (p< 0.01).Discussion.This study confirms the hypothesis that less range of motion is required to grip utensils with larger diameter handles, which in turn may reduce challenges for patients with limited ROM of the hand.

Inertial measurement unit (IMU) records of human movement can be converted into joint angles using a sensor-to-segment calibration, also called functional calibration. This study aims to compare the accuracy and reproducibility of four functional calibration procedures for the 3D tracking of the lower limb joint angles of young healthy individuals in gait. Three methods based on segment rotations and one on segment accelerations were used to compare IMU records with an optical system for their accuracy and reproducibility. The squat functional calibration movement, offering a low range of motion of the shank, provided the least accurate measurements. A comparable accuracy was obtained in other methods with a root mean square error below 3.6° and an absolute difference in amplitude below 3.4°. The reproducibility was excellent in the sagittal plane (intra-class correlation coefficient (ICC) > 0.91, standard error of measurement (SEM) < 1.1°), good to excellent in the transverse plane (ICC > 0.87, SEM < 1.1°), and good in the frontal plane (ICC > 0.63, SEM < 1.2°). The better accuracy for proximal joints in calibration movements using segment rotations was traded to distal joints in calibration movements using segment accelerations. These results encourage further applications of IMU systems in unconstrained rehabilitative contexts.

This paper presents the elbow flexion and extension rehabilitation exercise system using marker-less Kinect-based method. The proposed exercise system is developed for the upper limb rehabilitation application that utilizes a low cost depth sensor. In this study, the Kinect skeleton tracking method is used to detect and track the joints of upper limb and then measure the angle of the elbow joint. The users perform the exercise in front of the Kinect sensor and the computer monitor. At the same time, they can see the results that displayed on the screen in real-time. The measurement of elbow joint angles are recorded automatically and has been compared to the reference values for the analysis and validation. These reference values are obtained from the normal range of motion (ROM) of the elbow. The results show the average flexion angle of the elbow joint that achieved by the normal user is 139.1° for the right hand and 139.2° for the left hand. Meanwhile, the average extension angle is 1.72° for the right hand and 2.0° for the left. These measurements are almost similar to the standard range of motion (ROM) reference values. The skeleton tracking works well and able to follow the movement of the upper arm and forearm in real-time.

Full textAbstract:
Abstract Measuring and documenting shoulder motion is important for many reasons, including diagnosis, determining the severity and progression of a disorder, assessing the results of treatment, and evaluating impairment. The AMA Guides to the Evaluation of Permanent Impairment (AMA Guides), Sixth Edition provides guidance for the process of assessing abnormal motion of the shoulder, specifically Section 15.7a, Clinical Measurements of Motion, and Section 15.7g, Shoulder Motion. The shoulder has greater mobility than any other joint of the body, and movement there usually is composite rather than in a single plane; as a result, single movements are difficult to isolate. In the AMA Guides, universal goniometers with long arms are used to measure shoulder range of motion (ROM). Measurements of joint motion must be performed and recorded consistently because interrater reliability is reduced if instruments are incorrectly placed or if overlying soft tissue distorts the measurement. Active motion is obtained with full muscle force and cooperation after warm-up, and the ROM examination is performed by recording the active measurements from three separate ROM efforts. Patients may self-limit during the assessment of active range of motion or exert submaximal effort on manual strength testing because of pain and/or apprehension, so all measurements should fall within 10° of the mean and both sides should be tested.

Full textAbstract:
Background: Altered glenohumeral joint range of motion can be caused by increased humeral retroversion (HR) and/or posterior capsule tightness (PCT). To make informed clinical decisions, it is vital to understand how HR and PCT alterations, individually and in combination, affect joint range of motion measurements. Purpose: To evaluate the effect of experimental tissue alterations on clinical range of motion measures. Study Design: Controlled laboratory study. Methods: Five clinical measurements were quantified in 8 fresh-frozen cadavers under 4 experimentally created conditions: baseline (no alterations), HR condition (20° increase in HR by transecting the bone), PCT condition (20% decrease in length via thermal energy), and PCT + HR combined. Clinical measurements included bicipital forearm angle, low flexion, glenohumeral internal and external rotation, and horizontal adduction. All measurements were taken by the same blinded tester. Separate 1-factor repeated measures analyses of variance were used to evaluate the effect of the alterations on each clinical measurement. Results: There was a significant main effect of condition for bicipital forearm angle ( P = .02, F = 4.03), low flexion ( P = .02, F = 3.86), internal rotation ( P = .03, F = 3.65), and external rotation ( P < .001, F = 15.15) but not for horizontal adduction ( P = .29, F = 1.33). The HR condition resulted in a decreased bicipital forearm angle of 16.1° and 15.8° as compared with the PCT and PCT + HR conditions, respectively. When compared with baseline, the PCT + HR condition decreased the low flexion test by 13.5°, and the HR condition decreased internal rotation range of motion by 14.2°. All conditions increased external rotation when compared with baseline. Conclusion: Greater measurement changes were noted in both HR conditions, suggesting that bony alterations influence motion to a greater extent than posterior capsule alterations. Clinical Relevance: Clinicians should be aware that humeral retroversion will influence the measurement of posterior shoulder tightness.

Gait analysis has historically been implemented in laboratory settings only with expensive instruments; yet, recently, efforts to develop and integrate wearable sensors into clinical applications have been made. A limited number of previous studies have been conducted to validate inertial measurement units (IMUs) for measuring ankle joint kinematics, especially with small movement ranges. Therefore, the purpose of this study was to validate the ability of available IMUs to accurately measure the ankle joint angles by comparing the ankle joint angles measured using a wearable device with those obtained using a motion capture system during running. Ten healthy subjects participated in the study. The intraclass correlation coefficient (ICC) and standard error of measurement were calculated for reliability, whereas the Pearson coefficient correlation was performed for validity. The results showed that the day-to-day reliability was excellent (0.974 and 0.900 for sagittal and frontal plane, respectively), and the validity was good in both sagittal (r = 0.821, p < 0.001) and frontal (r = 0.835, p < 0.001) planes for ankle joints. In conclusion, we suggest that the developed device could be used as an alternative tool for the 3D motion capture system for assessing ankle joint kinematics.

Summary Objective: To evaluate the use of inertial measurement units (IMU) for quantification of canine limb kinematics. Methods: Sixteen clinically healthy, medium-sized dogs were enrolled. Baseline kinematic data were acquired using an optical motion capture system. Following this baseline data acquisition, a harness system was used for attachment of IMU to the animals. Optical kinematic data of dogs with and without the harness were compared to evaluate the influence of the harness on gait parameters. Sagittal plane joint kinematics acquired simultaneously with IMU and the optical system were compared for the carpal, tarsal, stifle and hip joints. Comparisons of data were made using the concordance correlation coefficient (CCC) test and evaluation of root mean squared errors (RMSE). Results: No significant differences were demonstrated in stance duration, swing duration or stride length between dogs instrumented with or without the harness, however, mean RMSE values ranged from 4.90° to 14.10° across the various joints. When comparing simultaneously acquired optical and IMU kinematic data, strong correlations were found for all four joints evaluated (CCC: carpus = 0.98, hock = 0.95, stifle = 0.98, hip = 0.96) and median RMSE values were similar across the joints ranging from 2.51° to 3.52°. Conclusions and Clinical relevance: Canine sagittal plane motion data acquisition with IMU is feasible, and optically acquired and IMU acquired sagittal plane kinematics had good correlation. This technology allows data acquisition outside the gait laboratory and may provide an alternative to optical kinematic gait analysis for the carpal, tarsal, stifle, and hip joints in the dog.

SummaryObjectives: The aim of this study was to evaluate angle-of-motion values for the forelimb and hindlimb in clinically healthy adult Santa Ines sheep by means of a standard goniometer.Methods: Twenty female Santa Ines sheep, ranging in age between three- to six-yearsold, and weighing 32–45 kg (mean ± standard deviation [SD]: 30.4 ± 3.7) were used. A standard transparent plastic goniometer was used to measure passive maximum flexion, maximum extension, and range-of-motion (ROM) of the shoulder, elbow, carpal, hip, stifle, and tarsal joints in the right and left limbs. The goniometric measurements were done with the sheep awake and in a standing position. The measurements were made in triplicate by two independent investigators.Results: In all evaluated joints, there was no significant difference either between the means of the two sides or between measurements performed by the two investigators. The mean ± SD values of the measurements (degrees) were as follows: 20 ± 1 (flexion), 170 ± 2 (extension), and 150 ± 2 (ROM) for the carpal joint; 34 ± 4 (flexion), 145 ± 6 (extension), and 110 ± 4 (ROM) for the elbow joint; 88 ± 2 (flexion), 144 ± 6 (extension), and 56 ± 5 (ROM) for shoulder joint; 35 ± 4 (flexion), 163 ± 3 (extension), and 129 ± 4 (ROM) for tarsal joint; 46 ± 4 (flexion), 146 ± 6 (extension), and 100 ± 4 (ROM) for the stifle joint; 54 ± 3 (flexion), 143 ± 7 (extension), and 89 ± 5 (ROM) for the hip joint.Clinical significance: The data obtained provide useful and objective information on the joints. More studies are necessary using other sheep breeds.

This article reviews the existing range-of-motion measurement literature related to ankle dorsiflexion and plantarflexion to determine whether the reliability of ankle range-of-motion measurements can be defined, how the characteristics of the study population or clinician affect reliability, and the level of responsiveness for these measures. A MEDLINE search was performed through February 2004, and 11 articles met the inclusion criteria established for this review. Ample evidence was found for intrarater reliability for ankle dorsiflexion and plantarflexion range of motion. Although some evidence for interrater reliability of dorsiflexion was found, little evidence for interrater reliability of plantarflexion range of motion was uncovered. On the basis of the current literature, the responsiveness of ankle joint range-of-motion measurements is uncertain and requires further studies using patient populations.

Measurement of ankle dorsiflexion is a routine part of the podiatric examination of children, yet the reliability of this measure is largely unknown in healthy individuals. This study assessed the intrarater and interrater reliability of the first and second resistance levels of sagittal ankle range of motion in 4- to 6-year-old children. The results show that measures of ankle dorsiflexion in children are highly variable among examiners, and, in general, gastrocnemius range of motion is more reliable than soleal range of motion.

AbstractDuring an eight-hour shift, an industrial worker will inevitably cycle through specific postures. Those postures can cause microtrauma on the musculoskeletal system that accumulates, which in turn can lead to chronic injury. To assess how problematic a posture is, the rapid upper limb assessment (RULA) scoring system is widely employed by the industry. Even though it is a very quick and efficient method of assessment, RULA is not a biomechanics-based measurement that is anchored in a physical parameter of the human body. As such RULA does not give a detailed description of the impact each posture has on the human joints but rather, an overarching, simplified assessment of a posture. To address this issue, this paper proposes the use of joint angles and torques as an alternative way of ergonomics evaluation. The cumulative motion and torque throughout a trial is compared with the average motions and torques for the same task. This allows the evaluation of each joint’s kinematic and kinetic performance while still be able to assess a task“at-a-glance”. To do this, an upper human body model was created and the mass of each segment were assigned. The joint torques and the RULA scores were calculated for simple range of motion (ROM) tasks, as well as actual tasks from a TV assembly line. The joint angles and torques series were integrated and then normalized to give the kinematic and kinetic contribution of each joint during a task as a percentage. This made possible to examine each joint’s strain during each task as well as highlight joints that need to be more closely examined. Results show how the joint angles and torques can identify which joint is moving more and which one is under the most strain during a task. It was also possible to compare the performance of a task with the average performance and identify deviations that may imply improper execution. Even though the RULA is a very fast and concise assessment tool, it leaves little room for further analyses. However, the proposed work suggests a richer alternative without sacrificing the benefit of a quick evaluation. The biggest limitation of this work is that a pool of proper executions needs to be recorded for each task before individual comparisons can be done.

Background. Pain of the spine and large appendicular joints may limit the functional mobility of elderly persons and affect their biological fitness. This paper assesses the effects of comprehensive physical therapy in women with lumbar and cervical pain and compares flexibility in the upper and lower body and the range of motion in selected joints. Material and methods. Thirty-three women aged 60–75 years completed a 6-week intervention involving group gymnastics to prevent back pain, relaxation techniques, classic massage, transcutaneous electrical nerve stimulation, and ultrasound therapy to the lumbosacral and cervicothoracic regions. Patient outcomes were assessed by measuring upper and lower body flexibility, upper and lower extremity joint and spinal ROM, and self-reported back pain using a Visual Analogue Scale. Differences in means between successive measurements were calculated with a Student t test for dependent groups, while differences in the range of motion in the joints of the right and left limbs were calculated with the NIR test. Results. The physical therapy significantly improved flexibility of the upper and lower body by increasing the range of motion in selected joints of the limbs and the spine. On completion of the intervention, the intensity of back pain was reduced by 2.9 points in the VAS scale. Conclusions. 1. The results confirm high efficacy of comprehensive physical therapy. 2. Elderly persons willingly attend exercise sessions combined with physical therapy procedures, as elimination of pain and improved functional efficacy facilitates self-care, thus significantly improving the quality of their lives.

Full textAbstract:
(1) Background: Measuring joint range of motion has traditionally occurred with a universal goniometer or expensive laboratory based kinematic analysis systems. Technological advances in wearable inertial measurement units (IMU) enables limb motion to be measured with a small portable electronic device. This paper aims to validate an IMU, the ‘Biokin’, for measuring shoulder range of motion in healthy adults; (2) Methods: Thirty participants completed four shoulder movements (forward flexion, abduction, and internal and external rotation) on each shoulder. Each movement was assessed with a goniometer and the IMU by two testers independently. The extent of agreement between each tester’s goniometer and IMU measurements was assessed with intra-class correlation coefficients (ICC) and Bland-Altman 95% limits of agreement (LOA). Secondary analysis compared agreement between tester’s goniometer or IMU measurements (inter-rater reliability) using ICC’s and LOA; (3) Results: Goniometer and IMU measurements for all movements showed high levels of agreement when taken by the same tester; ICCs > 0.90 and LOAs < ±5 degrees. Inter-rater reliability was lower; ICCs ranged between 0.71 to 0.89 and LOAs were outside a prior defined acceptable LOAs (i.e., > ±5 degrees); (4) Conclusions: The current study provides preliminary evidence of the concurrent validity of the Biokin IMU for assessing shoulder movements, but only when a single tester took measurements. Further testing of the Biokin’s psychometric properties is required before it can be confidently used in routine clinical practice and research settings.

Full textAbstract:
Background Serial joint range-of-motion (ROM) measurements are an important component of assessments for children with cerebral palsy. Most research has studied ROM stability using group data. Examination of longitudinal intraindividual measures may provide more clinically relevant information about measurement variability. Objective The aim of this study was to examine the stability of intraindividual longitudinal measurements of hip abduction (ABD), popliteal angle (POP), and ankle dorsiflexion (ADF) ROM measures of children with cerebral palsy. Design Secondary data analyses were performed. Methods The stability patterns of individual serial measurements of ABD, POP, and ADF from 85 children (mean age=3.8 years, SD=1.4) collected at baseline (T1), 3 months (T2), 6 months (T3), and 9 months (T4) were examined using T1 as the anchor and bandwidths of ±15 degrees (ABD and POP) and ±10 degrees (ADF) as acceptable variability. Frequencies of stability categories (0°–5°, 5.1°–10°, 10.1°–15°, and >15°) were calculated. Patterns of stability across the 4 time periods also were examined. Group means (T1–T4) were compared using repeated-measures analysis of variance. Results No significant differences in group means were found except for ABD. Stability patterns revealed that 43.3% to 69.5% of joint measurements were stable with T1 measurements across all 3 subsequent measurements. Stability category frequencies showed that many measurements (ABD=17%, POP=29.9%, and ADF=37.1%) went outside the variability bandwidths even though 39% or more of joint measurements had a change of 5 degrees or less over time. Limitations Measurement error and true measurement variability cannot be disentangled. The results cannot be extrapolated to other joint ROMs. Conclusions Individual ROM serial measurement exhibits more variability than group data. Range-of-motion data must be interpreted with caution clinically and efforts made to ensure standardization of data collection methods.

Context: Deficits in the hip range of motion are associated with hip and groin injuries. Accurate and reliable goniometric measurements are important in identifying those at risk of injury and determining the efficacy of treatment interventions. Smartphone goniometric applications are regularly used to assess joint ranges of motion; however, there is limited knowledge on the reliability of this method in relation to the hip, particularly between clinicians with different levels of experience. Objective: To determine the intratester and intertester reliability of a smartphone clinometer application for the assessment of hip goniometric measurements in healthy volunteers by an experienced and novice clinician. Design: Reliability study. Setting: University Athletic Therapy facility. Participants: Physically active, university students. Main Outcome Measures: The study determined the intra- and intertester (experienced vs novice clinician) reliability of goniometric measurements of the hip joint (modified Thomas test and seated hip internal and external rotation) using a smartphone goniometric application. Intraclass correlation coefficients (ICCs), standard error of measurement, and minimal detectable change at a 95% confidence interval were used to assess reliability. Results: Goniometric measurements demonstrated good to excellent relative intratester reliability for the modified Thomas test (ICC = .94), external rotation (ICC = .93–.95), and internal rotation (ICC = .80–.81). Intertester reliability for expert and novice clinicians was also excellent for the modified Thomas test (ICC = .98), external rotation (ICC = .95), and internal rotation (ICC = .92). Intratester and intertester standard error of measurement and minimal detectable change at 95% confidence interval values were similar for both testers and ranged from 1.9° to 3.6° and 5° to 10.1° and from 1.1° to 2.3° and 2.9° to 6.5°, respectively. Conclusion: Smartphone-based goniometric measurements of hip range of motion have high intratester and intertester reliability for novice and expert clinicians. It may be a useful, simple, and inexpensive resource for clinicians.
