Introduction. The aim of the study was to evaluate concurrent recording of ENG and VNG measurements in selected diagnostic tests in healthy subjects so as to explore potential sensitivity and applicability of this kind of testing in the diagnostics of vertigo. Material and methods. The study was carried out in 50 healthy subjects including 24 women and 26 men aged 20-22 (mean age of 20.5 years) reporting no otorhinolaryngological organ-related complaints and no history of any balance disorders or vertigo. Every patient underwent subjective and objective otoneurological tests, electronystagmographic (ENG) examination including calibration, head-tracking test, optokinetic nystagmus test, rotatory chair test, positional tests according to Cawthorne and Rosen, and Hallpike caloric test as well as videonystagmographic (VNG) examination which included calibration, spontaneous nystagmus evaluation, head-tracking test, positional tests according to Cawthorne and Rosen with neck rotation test, and Hallpike caloric test. At first, ENG and VNG examinations were carried out separately at a 24-hour interval. Concurrent ENG and VNG recording was carried out 48 hours following the last test, with calibration being performed again before both evaluations. The concurrent recording included the spontaneous nystagmus evaluation, positional tests according to Cawthrone and Rose with the neck rotation test, and Hallpike caloric test. Results. No negative mutual interference of the conducted tests has been observed. Both in the concurrent and in the separate recordings, the caloric test revealed lower values of the mean velocity of the nystagmus free phase in the ENG test as compared to the VNG test. No signs of spontaneous nystagmus, as well as no signs of optokinetic and positional nystagmus, were detected in any case. Conclusions. The conducted tests did not reveal any mutual excludability between the selected ENG and VNG diagnostic tests upon concurrent recording. However, the concurrent use of both examinations in the diagnostics of balance disorders and vertigo requires further studies.

OBJECTIVES: To compare the sensitivity of rotational chair (ROTO) versus electronystagmography (ENG) in peripheral vestibular pathology. METHODS: Retrospective chart review. RESULTS: One thousand consecutive patients undergoing evaluation for dizziness and imbalance at a tertiary care referral balance center were reviewed. ROTO was the primary vestibular study used in all patients with ENG used as a confirmatory test at the discretion of the treating physician. A subgroup of 478 patients underwent both ROTO and ENG. Among the patients diagnosed with peripheral vestibulopathy, sensitivity for peripheral vestibulopathy was 71% for ROTO and 31% for ENG. However, specificity was 54% for ROTO and 86% for ENG. CONCLUSIONS: We conclude that in this retrospective cohort with the authors’ clinical diagnoses, ROTO is a more sensitive diagnostic study of peripheral vestibular pathology. The higher sensitivity of ROTO and the higher specificity of ENG may support the use of ROTO as the primary vestibular study and ENG as a supplemental vestibular study. Prospective analysis with distinct diagnostic criteria and defined inclusion criteria are necessary before these results can be widely extrapolated.

AbstractAudiological and vestibular tests were administered conjointly in a neurological or general ORL clinic to exclude cerebellopontine angle (CPA) tumours. This study aimed to assess the efficiency of various tests in achieving that exclusion with the minimum of unnecessary investigations. All patients received the full battery of auditory brainstem responses, acoustic reflex thresholds and decay, alternate binaural loudness balance and ENG and caloric testing. All patients who did not have normal auditory brainstem responses proceeded to high resolution CT scanning. One hundred and fifteen patients were investigated and four acoustic neuromas were diagnosed. The efficiency of these tests in a general ORL clinic is very much poorer than often suggested, due largely to the number of occasions on which the tests cannot be done, and to the very small proportion of the test population who have CPA tumours.

Latar belakang: Gangguan keseimbangan merupakan efek samping pemberian streptomisin yang dapat menurunkan kualitas hidup. Saat ini belum didapatkan penelitian gangguan keseimbangan pada pasien tuberkulosis yang mendapat terapi streptomisin diperiksa menggunakan tes dynamic visual acuity (DVA) dan tes kalori. Tujuan: Penelitian ini bertujuan untuk melihat akurasi pemeriksaan keseimbangan dengan DVA pada pasien TB yang mendapatkan streptomisin dibandingkan dengan elektronistagmografi (ENG). Metode: Penelitian ini merupakan penelitian pra-eksperimental untuk mengetahui perubahan hasil pemeriksaan fungsi keseimbangan vestibuler pada suatu kelompok pasien TB sebelum dan setelah 56 kali pemberian streptomisin, atau bila timbul keluhan gangguan keseimbangan dengan tes DVA dan tes kalori selama April-Oktober 2014. Digunakan rancangan uji diagnostik untuk membandingkan kedua cara pengukuran setelah pengobatan. Hasil: Setelah pemberian terapi didapatkan 31 (77,5%) dari 40 subjek dengan pemeriksaan kalori dan 30 (75%) dengan pemeriksaan DVA. Rerata nilai kalori sebelum terapi sebesar 93,5±32,07°/detik dan setelah terapi sebesar 82,30±38,43°/detik, terjadi perubahan sebesar -11,25±50,55°/detik. Median nilai kenaikan DVA sebelum terapi adalah 0 (minimal 0-maksimal 2) baris dan setelah terapi adalah 3 (minimal 0-maksimal 6) baris, terjadi perubahan sebesar 3 (minimal 0-maksimal 5) baris. Sensitivitas pemeriksaan DVA 83%, spesifisitas 27%, nilai duga positif 17%, nilai duga negatif 90%, rasio kemungkinan positif 1,13, dan rasio kemungkinan negatif 0,63 dengan pemeriksaan kalori sebagai baku emas. Kesimpulan: Pemeriksaan DVA dapat digunakan sebagai skrining pemeriksaan kelemahan vestibuler perifer bilateral pada pasien tuberkulosis yang mendapat terapi streptomisin.Background: Impaired balance is the side effect of Streptomycin administration which can decrease the quality of life Up till now, there is no research yet on dynamic visual acuity (DVA) and caloric test in tuberculosis (TB) patients receiving streptomycin therapy. Objective: This study aims to look at the accuracy of the examination using DVA in TB patients receiving Streptomycin, compared to using electronistagmography (ENG). Methods: A pre-experimental study was used to determine changes in the vestibular function test results in a group of TB patients before and after56times administrationof Streptomycin, or when subjects complained of balance disorders, with DVA test and caloric test during April-October 2014. Designed diagnostic test was used after treatment to compare the two methods of measurement. Result: After therapy there was 31 (77.5%) out of 40 subjects with caloric examination and in 30 (75%) with DVA examination. The mean value of caloric examination before therapy was 93.5±32.07°/sec and after therapy was 82.30±38.43°/sec, the change was -11.25±50.55°/sec. The median value of increased DVA line before therapy was 0 line and after therapy was 3 line, there was a change of 3 (minimum 0-maximum 5) line. DVA examination has a sensitivity of 83%, a specificity of 27%, positive predictive value 17%, negative predictive value 90%, a positive likelihood ratio 1.13 and a negative likelihood ratio 0.63 with caloric examination as the gold standard. Conclusion: DVA examination can be used as a screening tool in bilateral peripheral vestibular weakness in TB patients who received Streptomycin therapy.

Full textAbstract:
Background: Postural stability in humans is largely maintained by vestibular, visual, and somatosensory inputs to the central nervous system. Recent clinical advances in the assessment of otolith function (e.g., cervical and ocular vestibular evoked myogenic potentials [cVEMPs and oVEMPs], subjective visual vertical [SVV] during eccentric rotation) have enabled investigators to identify patients with unilateral otolith impairments. This research has suggested that patients with unilateral otolith impairments perform worse than normal healthy controls on measures of postural stability. It is not yet known if patients with unilateral impairments of the saccule and/or inferior vestibular nerve (i.e., unilaterally abnormal cVEMP) perform differently on measures of postural stability than patients with unilateral impairments of the horizontal SCC (semicircular canal) and/or superior vestibular nerve (i.e., unilateral caloric weakness). Further, it is not known what relationship exists, if any, between otolith system impairment and self-report dizziness handicap. Purpose: The purpose of this investigation was to determine the extent to which saccular impairments (defined by a unilaterally absent cVEMP) and impairments of the horizontal semicircular canal (as measured by the results of caloric testing) affect vestibulospinal function as measured through the Sensory Organization Test (SOT) of the computerized dynamic posturography (CDP). A secondary objective of this investigation was to measure the effects, if any, that saccular impairment has on a modality-specific measure of health-related quality of life. Research Design: A retrospective cohort study. Subjects were assigned to one of four groups based on results from balance function testing: Group 1 (abnormal cVEMP response only), Group 2 (abnormal caloric response only), Group 3 (abnormal cVEMP and abnormal caloric response), and Group 4 (normal control group). Study Sample: Subjects were 92 adult patients: 62 were seen for balance function testing due to complaints of dizziness, vertigo, or unsteadiness, and 30 served as controls. Intervention: All subjects underwent videonystagmography or electronystagmography (VNG/ENG), vestibular evoked myogenic potentials (VEMPs), self-report measures of self-perceived dizziness disability/handicap (Dizziness Handicap Inventory), and tests of postural control (Neurocom Equitest). Data Collection and Analysis: Subjects were categorized into one of four groups based on balance function test results. All variables were subjected to a multifactor analysis of variance (ANOVA). The Dizziness Handicap Inventory (DHI) total scores and equilibrium scores served as the dependent variables. Results: Results showed that patients with abnormal unilateral saccular or inferior vestibular nerve function (i.e., abnormal cVEMP) demonstrated significantly impaired postural control when compared to normal participants. However, this group demonstrated significantly better postural stability when compared to the group with abnormal caloric responses alone and the group with abnormal caloric responses and abnormal cVEMP results. Patients with an abnormal cVEMP did not differ significantly on the DHI compared to the other two impaired groups. Conclusions: We interpret these findings as evidence that a significantly asymmetrical cVEMP in isolation negatively impacts performance on measures of postural control compared to normal subjects but not compared to patients with significant caloric weaknesses. However, patients with a unilaterally abnormal cVEMP do not differ from patients with significant caloric weaknesses in regard to self-perceived dizziness handicap.

In order to analyze different human brain states related to perception and maintaining of body posture, we implemented an experiment with a balance platform. It is known the cerebral cortex regulates subcortical postural centers to maintain upright balance and posture and balance demands. However, the cortical mechanisms that support standing balance remain elusive. In this work, we present an EEG-based analysis during execution of balance responses with distinct postural demands. The results suggest the existence of common features in the EEG structure associated with distinct activity during balance maintaining. This may give new directions for future research in the field of brain activity, and for the development of brain-computer interfaces.

Abstract This paper presents a balanced tropical cyclone (TC) test case designed to improve current understanding of how atmospheric general circulation model (AGCM) configurations affect simulated TC development and behavior. It consists of an analytic initial condition comprising two independently balanced components. The first provides a vortical TC seed, while the second adds a planetary-scale zonal flow with height-dependent velocity and imposes background vertical wind shear (VWS) on the TC seed. The environmental flow satisfies the steady-state hydrostatic primitive equations in spherical coordinates and is in balance with other background field variables (e.g., temperature, surface geopotential). The evolution of idealized TCs in the test case framework is illustrated in 10-day simulations performed with the Community Atmosphere Model, version 5.1.1 (CAM 5.1.1). Environmental wind profiles with different magnitudes, directions, and vertical inflection points are applied to ensure that the technique is robust to changes in the VWS characteristics. The well-known shear-induced intensity change and structural asymmetry in tropical cyclones are well captured. Sensitivity of TC evolution to small perturbations in the initial vortex is also quantitatively addressed to validate the numerical robustness of the technique. It is concluded that the enhanced TC test case can be used to evaluate the impact of model choice (e.g., resolution, physical parameterizations) on the simulation and representation of TC-like vortices in AGCMs.

Full textAbstract:
Walking ability is a vital component of validated test procedures to assess mobility impairment in multiple sclerosis (MS). The methods used to assess walking ability vary widely between treatment centres, and the accuracy of the methods used and numbers of parameters determined to analyse specific aspects of walking and gait are often limited. The questionnaire- and task-based methods used to assess walking in MS can be divided into different categories. First, there are the general-purpose tests such as the Expanded Disability Status Scale (EDSS), the Multiple Sclerosis Functional Composite (MSFC), the Family Assessment of Multiple Sclerosis Trial Outcome Index (FAMS-TOI) and the Short Form-36 (SF-36). These, particularly EDSS, are widely used in MS to assess limitations of all activities and social participation, of which walking is only a part. Others, such as SF-36, assess health-related quality of life (HRQoL). Second, there are methods designed to specifically assess walking or gait, including the timed 25-foot walk (T25FW), the Dynamic Gait Index (DGI), the 12-Item MS Walking Scale (MSWS-12) and the Timed Up and Go Test (TUGT). These test methods require minimal equipment to perform such as a stopwatch, a hallway or a chair, and can be completed at a medical centre in a few minutes. Most of these tests provide reliable and valid data but some lack accurate assessment of gait and some require clinician training. Third, there are tests that specifically measure balance, such as the Berg Balance Test, in which the patient completes a series of balance exercises while being observed. A recent development is the use of accelerometers to monitor MS patients over extended periods; these can provide more accurate data than patient self-report tools. In future, it is likely that more specific tests of walking ability will be more widely used as an important part of MS diagnosis and to more precisely monitor disease progression and assess patient needs.

Full textAbstract:
This exploratory study aimed to monitor long-term seasonal developments in measures of anthropometry, body composition, and physical fitness in young judo athletes, and to compute associations between these measures and sporting success. Forty-four young judoka (20 females, 24 males) volunteered to participate. Tests for the assessment of anthropometry (e.g., body height/mass), body-composition (e.g., lean body mass), muscle strength (isometric handgrip strength), vertical jumping (e.g., countermovement-jump (CMJ) height), and dynamic balance (Y-balance test) were conducted at the beginning and end of a 10-month training season. Additionally, sporting success at the end of the season was recorded for each athlete. Analyses revealed significant time × sex interaction effects for lean-body-mass, isometric handgrip strength, and CMJ height (0.7 ≤ d ≤ 1.6). Post-hoc analyses showed larger gains for all measures in young males (1.9 ≤ d ≤6.0) compared with females (d = 2.4) across the season. Additionally, significant increases in body height and mass as well as Y-balance test scores were found from pre-to-post-test (1.2 ≤ d ≤4.3), irrespective of sex. Further, non-significant small-to-moderate-sized correlations were identified between changes in anthropometry/body composition/physical fitness and sporting success (p > 0.05; −0.34 ≤ ρ ≤ 0.32). Regression analysis confirmed that no model significantly predicted sporting success. Ten months of judo training and/or growth/maturation contributed to significant changes in anthropometry, body composition, and physical fitness, particularly in young male judo athletes.

Context:The Star Excursion Balance Test (SEBT) is often used to train and assess dynamic balance and neuromuscular control. Few studies have examined hip- and thigh-muscle activation during the SEBT.Objective:To quantify hip- and thigh-muscle activity during the SEBT.Design:Repeated measures.Setting:Laboratory.Participants:22 healthy individuals, 11 men and 11 women.Methods:EMG measurements were taken as participants completed 3 trials of the anterior (A), medial (M), and posteromedial (PM) reach directions of the SEBT.Main Outcome Measures:Mean EMG data (% maximal voluntary isometric contraction) from the gluteus medius (Gmed), gluteus maximus (Gmax), and vastus medialis (VM) were measured during the eccentric phase of each SEBT reach direction. Test–retest reliability of EMG data across the 3 trials in each direction was calculated. EMG data from each muscle were compared across the 3 reach directions.Results:Test–retest reliability ranged from ICC3,1 values of .91 to .99. A 2-way repeated-measure ANOVA revealed a significant interaction between muscle activation and reach direction. One-way ANOVAs showed no difference in GMed activity between the A and M directions. GMed activity in the A and M directions was greater than in the PM direction. There was no difference in GMax and VM activity across the 3 directions.Conclusion:GMed was recruited most effectively when reaching was performed in the A and M directions. The A, M, and PM directions elicited similar patterns of muscle recruitment for the GMax and VM. During all 3 SEBT directions, VM activation exceeded the 40–60% threshold suggested for strengthening effects. GMed activity also exceeded the threshold in the M direction. GMax activation, however, was below the 40% threshold for all 3 reach directions, suggesting that performing dynamic lower extremity reaching in the A, M, and PM directions may not elicit strengthening effects for the GMax.

Background. The imbalance in many scientific sources is described as a major disorder in patients with a history of stroke. Often, the importance or disruption of torso control is also indicated on balance impairments. We believe that both physiotherapy programs will have impact on balance however better results on balance tests will be in group which balance training composed of unstable planes. Research aim was to measure impact of various physiotherapy programs on static and dynamic balance for patients after stroke. Methods. To evaluate changes of static and dynamic balance we used: Berg balance test, Tinetti test, PASS test, dynamic gait index, trunk impairment scale, special STREAM movements test for patients after stroke, Mini balance evaluation test for patients after stroke. Training methods of balance were for two different physiotherapy programs: intervention group (basic physiotherapy program with exercises on unstable planes) and control group (basic physiotherapy program with gait training elements). Results. When evaluating balance, results in both groups were almost equal, which shows that balance was disturbed and there was a huge risk of falls, moreover all patients walked with aid measures. At the beginning of rehabilitation, the average of all balance evaluating tests in both groups scored 16.92 and 15.05. All results were statistically significant (p < .05). At the end of research, variations between all test results were defined statistically significant. Repeatedly evaluating results of both groups at the end of rehabilitation, all test averages were improved: at the beginning, the intervention group average score was 16.92 and after rehabilitation, it was 34.79. For control group results, the average score of all tests was 15.05 and at the end it was 31.90. Summing up, it was established that in both groups balance in rehabilitation period improved. Conclusions. Physiotherapy programs based on exercises on unstable planes or gait training elements improve balance for patients after stroke. Many studies have confirmed the hypothesis of our study that using unstable planes or walking training methods improve balance, but for a statistically significant change in improving the balance, it will be necessary to use unstable planes.

Full textAbstract:
Background:Motion sickness may be caused by a sensory conflict between the visual and the vestibular systems. Scopolamine, known to be the most effective therapy to control the vegetative symptoms of motion sickness, acts on the vestibular nucleus and potentially the vestibulospinal pathway, which may affect balance and motor tasks requiring both attentional process and motor balance. The aim of this study was to explore the effect of scopolamine on motor control and attentional processes.Methods:Seven subjects were evaluated on four different tasks before and after a subcutaneous injection of scopolamine (0.2 mg): a one-minute balance test, a subjective visual vertical test, a pointing task and a galvanic vestibular stimulation with EMG recordings.Results:The results showed that the reaction time and the movement duration were not modified after the injection of scopolamine. However, there was an increase in the center of pressure displacement during the balance test, a decrease in EMG muscle response after galvanic vestibular stimulation and an alteration in the perception of verticality.Discussion:These results confirm that low doses of scopolamine such as those prescribed to avoid motion sickness have no effect on attentional processes, but that it is essential to consider the responsiveness of each subject. However, scopolamine did affect postural control and the perception of verticality. In conclusion, the use of scopolamine to prevent motion sickness must be considered carefully because it could increase imbalances in situations when individuals are already at risk of falling (e.g., sailing, parabolic flight).

The long series of mass-balance data obtained by the Norsk Polarinstitutt on Brøggerbreen for the period 1967–88 has been correlated to climatological parameters from the meteorological station in Ny-Ålesund. The best multiple correlation coefficient was obtained between mass balance and positive summer and autumn temperatures combined with winter precipitations, for which R = 0.90. The regression equation gives a very good agreement between observed and estimated mass balance for Brøggerbreen. A test for 8 years which includes summer long-wave radiation, gives a coefficient of R = 0.98. Based on the good correlation between temperatures at several stations, we reconstructed summer temperatures in Longyearbyen and Brøggerbreen mass balances for 1912–88. The end of the cold period before 1918 is connected with historical observations of the maximum advance of cirque glaciers. After an increase between 1912 and 1920, summer and autumn temperatures decreased slowly. From 1920 this decay has been of −0.7°C. Mass balance has been negative since 1918, and the total mass lost at Brøggerbreen is 34.35 m of water equivalent. For the period with available data in Ny-Ålesund (1969–88), a very slight cooling during the ablation period and an increase in winter precipitation has maintained the reduction of the net balance deficit.

Full textAbstract:
Purpose The purpose of this paper is to investigate the mediating roles of work and family demands and work-life balance on the relationship between self-efficacy (to regulate work and life) and work engagement. Specifically, it seeks to explain how self-efficacy influences employees’ thought patterns and emotional reactions, which in turn enable them to cope with work and family demands, and ultimately achieve work-life balance and work engagement. Design/methodology/approach Structural equation modelling (SEM) of survey data obtained from a heterogeneous sample of 1,010 Australian employees is used to test the hypothesised chain mediation model. Findings The SEM results support the hypothesised model. Self-efficacy was significantly and negatively related to work and family demands, which in turn were negatively associated with work-life balance. Work-life balance, in turn, enabled employees to be engaged in their work. Research limitations/implications The findings support the key tenets of social cognitive theory and conservation of resources (COR) theory and demonstrate how self-efficacy can lead to work-life balance and engagement despite the presence of role demands. Study limitations (e.g. cross-sectional research design) and future research directions are discussed. Originality/value This study incorporates COR theory with social cognitive theory to improve understanding of how self-efficacy enhances work-life balance and work engagement through a self-fulfilling cycle in which employees achieve what they believe they can accomplish, and in the process, build other skills and personal resources to manage work and family challenges.

Full textAbstract:
There is a lack of evidence about the ways in which balance ability influences the kinematic and kinetic parameters and muscle activities during gait among healthy individuals. The hypothesis is that balance ability would be associated with the lower limb kinematics, kinetics and muscle activities during gait. Twenty-nine healthy volunteers (Age 32.8 ± 9.1; 18 males and 11 females) performed a Star Excursion Balance test to measure their dynamic balance and walked for at least three trials in order to obtain a good quality of data. A Vicon® 3D motion capture system and AMTI® force plates were used for the collection of the movement data. The selected muscle activities were recorded using Delsys® Electromyography (EMG). The EMG activities were compared using the maximum values and root mean squared (RMS) values within the participants. The joint angle, moment, force and power were calculated using a Vicon Plug-in-Gait model. Descriptive analysis, correlation analysis and multivariate linear regression analysis were performed using SPSS version 23. In the muscle activities, positive linear correlations were found between the walking and balance test in all muscles, e.g., in the multifidus (RMS) (r = 0.800 p < 0.0001), vastus lateralis (RMS) (r = 0.639, p < 0.0001) and tibialis anterior (RMS) (r = 0.539, p < 0.0001). The regression analysis models showed that there was a strong association between balance ability (i.e., reaching distance) and the lower limb muscle activities (i.e., vastus medialis–RMS) (R = 0.885, p < 0.0001), and also between balance ability (i.e., reaching distance) and the lower limb kinematics and kinetics during gait (R = 0.906, p < 0.0001). In conclusion, the results showed that vastus medialis (RMS) muscle activity mainly contributes to balance ability, and that balance ability influences the lower limb kinetics and kinematics during gait.

Full textAbstract:
Connectedness with nature refers to an individual’s beliefs about their relationship with the natural environment. The current paper integrates connectedness with nature into a broader framework of balanced identity theory as a form of self-concept, and presents new data showing that individuals tend toward balanced-congruity and hold cognitive configurations that balance self-concept, environmental attitudes, and self-esteem. In essence, when an individual scores highly on one of these constructs, it is likely that they will score highly on the other two constructs. Two hundred and seventy-six undergraduate students completed explicit and implicit measures of connectedness with nature, attitudes toward nature, and self-esteem. The balanced-congruity principle was supported with implicit measures (e.g., Implicit Association Test), but not explicitly with self-report measures. Results suggest that attitudes toward nature, connectedness with nature, and self-esteem form a balanced triadic structure of implicit environmental identity. The findings extend our understanding of connectedness with nature, by integrating it into a broader framework that links connectedness, attitudes, and self-esteem as a triadic form of environmental identity. This finding has important implications for practitioners interested in fostering environmental identities and promoting sustainability.

This study was performed to evaluate the effects of EMG-triggered functional electrical stimulation on balance and gait ability on patient with Chronic Stroke. A total of 60 chronic stroke patients were divided into mirror treatment and functional electrical (MT-EF) Group, MT group, CON group. Each group performed 60 min a day five times a week for eight weeks. MT-FE group was performed 30 min five times a week for eight weeks in mirror therapy process with EMG-FES. MT group performed 30 min five times a week for eight weeks in mirror therapy process. CON group was performed 30 min five times a week for eight weeks in conservative treatment. To measure the balance ability, Biorescue (COP, LOS), Berg balance scale (BBS) and FRT, and the gait ability test was performed by 10 m walk test. MT-FE group revealed significant differences in COP, LOS, BBS, FRT and 10 m walk test as compared to the MT and CON groups (p < 0.05). Our results showed that MT-FE was more effective on COP, LOS, BBS, FRT and 10 m walk test in patients with chronic stroke. Our results also showed that MT-EF group was more effective on balance and gait ability in patients with chronic stroke. We suggest that this study can be used for intervention data for recovering balance and gait ability in chronic stroke patients.

Full textAbstract:
A variety of cognitive assessment tools are used to determine the functional status of the brain before and after injury in athletes. Questionnaires, neuropsychological tests, and electroencephalographic (EEG) measures have been recently used to directly assess brain function on and near the playing field. However, exercise can affect cognitive performance and EEG measures of cortical activity. To date, little empirical evidence exists on the effects of acute exercise on these measures of neurological function. We therefore quantified athlete performance on a standardized battery of concussion assessment tools and EEG measurements immediately before and after acute exercise to simulate conditions of athletic competition. Heart rate and arterial oxygen levels were collected before and after the exercise challenge consisting of a 1-mile run. Together these data, from a gender-balanced cohort of collegiate athletes, demonstrated that moderate to hard levels of acute exercise improved performance on the King-Devick test (K-D test) and Standardized Assessment of Concussion (SAC) component of the Sport Concussion Assessment Tool (SCAT3). Gender played an important role in these effects, and performance was most affected by exercise in female athletes. EEG activity in the theta band (4–8 Hz) was decreased during periods of quiet resting with eyes open or eyes closed. Additionally, exercise produced a slowing of the EEG during the K-D test and a shift to higher frequencies during the balance assessment of the SCAT3. Together, these data indicate that exercise alone can influence outcome measures of cognitive assessment tools used to assess brain function in athletes. Finally, care must be taken to acquire postinjury measurements during a comparable physiologic state to that in which baseline assessment data were measured, and further research is needed into the factors influencing outcome measures of these tests.

Abstract. Accurate determination of carbon balances in heterogeneous ecosystems often requires the extrapolation of point based measurements. The ground resolution (pixel size) of the extrapolation base, e.g. a land-cover map, might thus influence the calculated carbon balance, in particular if biogeochemical hot spots are small in size. In this paper, we test the effects of varying ground resolution on the calculated carbon balance of a boreal peatland consisting of hummocks (dry), lawns (intermediate) and flarks (wet surfaces). The generalizations in lower resolution imagery led to biased area estimates for individual micro-site types. While areas of lawns and hummocks were stable below a threshold resolution of ~60 cm, the maximum of the flark area was located at resolutions below 25 cm and was then decreasing with coarsening resolution. Using a resolution of 100 cm instead of 6 cm led to an overestimation of total CO2 uptake of the studied peatland area (approximately 14 600 m2) of ~5% and an underestimation of total CH4 emission of ~6%. To accurately determine the surface area of scattered and small-sized micro-site types in heterogeneous ecosystems (e.g. flarks in peatlands), a minimum ground resolution appears necessary. In our case this leads to a recommended resolution of 25 cm, which can be derived by conventional airborne imagery. The usage of high resolution imagery from commercial satellites, e.g. Quickbird, however, is likely to underestimate the surface area of biogeochemical hot spots. It is important to note that the observed resolution effect on the carbon balance estimates can be much stronger for other ecosystems than for the investigated peatland. In the investigated peatland the relative hot spot area of the flarks is very small and their hot spot characteristics with respect to CH4 and CO2 fluxes is rather modest.

For years, investors and accountants have speculated that managers “window dress,” that is, undertake actions to improve their balance sheets before they issue their financial reports. Similarly, institutional money managers are said to adjust their stock portfolios before the release of their quarterly reports. In this paper, stock market volume data for the overall market and for a number of different sample portfolios are examined to see if there is abnormal end-of-period trading activity. The results suggest that trading activity increases at the end of each quarter. This result is consistent with the window dressing hypothesis.

Study design:Retrospective cohort study.Background:Persons with a lower limb amputation can regain mobility using a prosthetic device. For fast and adequate prescription of prosthetic components, it is necessary to predict the mobility outcome early in rehabilitation. Currently, prosthetic prescription is primarily based on empirical knowledge of rehabilitation professionals.Objective:In this study, we explored motor ability tests, to be completed without a prosthetic device, which have predictive value for mobility outcome at the end of rehabilitation.Methods:For this study, data of 82 patients with a lower limb amputation were included. The Single-limb standing balance test (Balance test), the Lower-Extremity Motor Coordination Test and the Amputee Mobility Predictor Assessment Tool (AMPnoPRO) were used as measures for motor ability. Mobility outcome was measured using the Timed Up and Go Test, the Two-Minute Walking Test and K levels were used.Results:The explained variance of the Balance test, the Lower-Extremity Motor Coordination Test and the AMPnoPRO was, respectively, 0.603, 0.534 and 0.649 on the Two-Minute Walking Test (linear regression); 0.597, 0.431 and 0.624 on the Timed Up and Go Test (linear regression); and 0.432, 0.420 and 0.526 on the K levels (logistic regression).Conclusion:The AMPnoPRO predicted mobility outcome statistically (largest amount of explained variance).Clinical relevanceThis study explored the possibility of statistically predicting mobility outcome in lower limb amputees at the end of rehabilitation, using motor ability tests conducted in early rehabilitation. This study suggests the use of the AMPnoPRO to predict mobility outcome in lower limb amputees.

The objective of the present investigation was to relate quality of life and dynamic balance in older adults. To this end, an intentional sample of older adults was taken from the gerontological centers of Chambo and Guano cantons, for which 35 people make up the control group (Chambo); while 71 people make up the intervention group (Guano). In order to reach the goal of the research, the quality of life was evaluated, through a pre-test called WHOQOL - BREF, followed by the Tinetti test that refers to the march - balance, ending with the Timed get up and go test, which determines the mobility measures of people who can walk on their own. To the intervention group, an exercise program was applied to improve the dynamic balance that lasted ten weeks. Finally, by means of a post test, the entire sample was evaluated, which allowed us to analyze whether there was an incidence. In other words, a slight improvement in both dynamic balance and gait after ten weeks of intervention was evidenced.

Clinical practice and some scientific evidence seem to suggest that there is some kind of relationship between the components that form the postural chain. For professional dancers, good posture and balance are essential. The aim of the present retrospective study is to evaluate whether gnathological treatment could have an impact on the postural balance and sports performance of professional ballet dancers. Electromyographic (EMG) data and balance tests were recorded before and after six months of treatment with a customized occlusal splint. Twenty athletes were examined during ballet exercises in terms of balance and speed of execution by two experienced clinicians. The results showed statistically significant changes for all EMG tests carried out and the Flamingo Balance Test. It appears that the use of a customized occlusal device improved neuro-muscular coordination and the overall performance of dancers.

ABSTRACT This case helps prepare students for internships and careers in the audit profession by providing them with a realistic simulation of year-end substantive testing of Accounts Receivable. Students are given an audit program for testing management's assertions for the Accounts Receivable balance, and they are provided realistic supporting documentation with which to conduct their tests. Throughout the simulation, students will perform the following procedures: (1) identifying the correct supporting documents for each test and how to perform the required test work, (2) learning how to properly document their findings, (3) identifying any audit issues that arise during the performance of their test work, (4) rendering judgment for common issues that arise during the audit of the revenue cycle, (5) tying the supporting work papers to the trial balance and financial statements, and (6) understanding how an auditor can provide reasonable assurance about an account balance through substantive test work.

Full textAbstract:
(1) Background: Balance decline is highly prevalent in people suffering from chronic ankle instability (CAI). The control of balance depends upon multiple neurophysiologic systems including the activation of cortical brain regions (e.g., the primary sensorimotor cortex). The excitability of this region, however, is diminished in people with CAI. In this pilot double-blinded randomized controlled trial, we tested the effects of high-definition transcranial direct current stimulation (HD-tDCS) designed to facilitate the excitability of M1 and S1 in combination with short-foot exercise (SFE) training on proprioception and dynamic balance performance in individuals with CAI. (2) Methods: Thirty young adults completed baseline assessments including the Active Movement Extent Discrimination Apparatus (AMEDA), Joint Position Reproduction (JPR) test, Y-balance test, and the Sensory Organization Test (SOT). They were then randomized to receive a four-week intervention of SFE in combination with tDCS (i.e., HD-tDCS+SFE) or sham (i.e., control) stimulation. Baseline assessments were repeated once-weekly throughout the intervention and during a two-week follow-up period. (3) Results: Twenty-eight participants completed this study. Blinding procedures were successful and no adverse events were reported. As compared to the control group, the HD-tDCS+SFE group exhibited significant improvements in the JPR test, the Y balance test, and the SOT at different time points. No group by time interaction was observed in AMEDA test performance. (4) Conclusions: HD-tDCS combined with SFE may improve dynamic balance and proprioception in CAI. Larger, more definitive trials with extended follow-up are warranted.

The aim of this study was to evaluate the effects of gymnastics training combined with music on balance, loco-motor level and coordination in children with autism spectrum disorder (ASD) and down syndrome (DS). This randomized, controlled experimental trial included 30 children (15 children with DS, 15 children with ASD) aged 8 to 14 years. The children were separated into 2 groups, as Group 1 in which ASD and Group 2 in which DS treated gymnastics training with music for 16 weeks, 2 days a week, 1.5-2 hours. Flamingo balance test, functional reach test, Wall Catch coordination test and flexibility test were used to evaluate balance, dynamic balance, loco-motor level and coordination, flexibility, respectively. All groups were evaluated before training and at the end of 16 weeks. When the pre-training and post-training parameters were compared between the groups, a increase was determined in the parameters of balance, loco-motor level and coordination, flexibility in Group1. This increase was statistically greater in Group 1. Statistically significant difference was determined in Group 2 with respect to functional reach test, sit and reach test values. No statistically significant difference was determined in Group 2 in respect of Flamingo and Wall Catch coordination tests. As a result; gymnastics training combined with music were found to be effective in increase balance score, improving loco-motor level, coordination, flexibility in children with DS and ASD. The results of this study can be considered to provide important contributions to the understanding and treatment of children with autism and down syndrome.

Parkinson’s disease (PD) is a neurodegenerative disease in which gait and balance disturbances are relevant symptoms that respond poorly to pharmacological treatment. The aim of this study was to investigate whether a 4-week inpatient multidisciplinary intensive rehabilitation treatment (MIRT) is effective in improving balance and gait and whether improvements persist at a one-year followup. We studied 20 PD inpatients (stage 3 Hoehn-Yahr) who underwent a MIRT. Outcome measures were UPDRS items for balance (30), falls (13), and walk (29), Berg Balance Scale, six-minute walking test, Timed Up and Go Test, and Comfortable-Fast gait speeds. Patients were evaluated at admission, at the end of the 4-week treatment, and at a 1-year followup. Pharmacological therapy was unchanged during MIRT and follow-up. All outcome measures improved significantly at the end of treatment. At 1-year follow-up control, UPDRS walk and Comfortable-Fast gait speeds still maintained better values with respect to admission (P=0.009,P=0.03,andP=0.02, resp.), while the remaining scales did not differ significantly. Our results demonstrate that the MIRT was effective in improving balance and gait and that the improvement in gait performances was partially maintained also after 1 year.

This study examined the effects of using Physical Best lessons to promote adolescent energy balance knowledge and task values. Seventh graders ( N = 90) were randomly assigned to the experiment and the comparison groups. The experiment group took 10 selected Physical Best lessons, while the comparison experienced 10 district lessons. Pre- and post-measurements of knowledge and task values were taken at the beginning and the end of the experiment. Analysis of covariance and multivariate analysis of variance were conducted to test the difference over time and between the groups in energy balance knowledge test scores and task values. Both groups improved knowledge test scores, but the experiment group scored significantly higher than the comparison, controlling for the pre-test. The comparison group reported higher initial attainment values which declined over time, while the experiment group increased. The findings suggested that Physical Best lessons were effective ( ηp2=.18) in improving students’ energy balance knowledge in 10 structured lessons, and that students reported a higher perceived value about the importance of physical education after they learned energy balance and exercise principles. Perhaps these concepts should be taught in physical education to improve student knowledge and perceived values of the subject.

 Core stability and the ability to balance have both a critical role in today’s modern soccer. Majority of injuries originated from the weakness and inefficient strength of core musculature and the kinetic chain. The purpose of our study was to investigate the effect of a three month proprioceptive training programme on core stability and the ability to balance. We hypothesized that both of the skills might improve by the end of the 12-week exercise program. We set up a group involving 15 players, who regularly participated in a weekly 40 minutes special proprioceptive training routine. The control group hasn’t attended any additional strengthening workout session. The youngsters executed a fitball balancing task, in a seated position, and the so-called Stork-test. Before the 3-month exercise program, we implemented a pre-, at the end of the program a post-test. According to our results, we may conclude that we had measured a significant difference only in the Fitball-test when players executed the single leg balancing test (Stork-test), we haven’t observed any significant difference.

Purpose: This quasi-experimental and applied research was conducted in 2019. The statistical population of this study included female patients with Multiple Sclerosis (MS) who were members of the Iranian MS Association. Methods: The study subjects were selected among those with a moderate level of disability (between grades 2 & 5). From the statistical population, initially, 60 individuals were selected by a simple and accessible method; however, for some reason, some samples dropped out during the research. In total, 14, 15, and 19 individuals included the balance, Cawthorne-Cooksey, and control groups, respectively. They were selected based on the study inclusion and exclusion criteria. The three groups were evaluated for static balance by the stork test; then, their mobility was measured by the Timed Up and Go (TUG) test at the pretest phase. Next, the two experimental groups performed the exercises for 6 weeks and 3 sessions per week. Besides, at the end of the exercise protocol, the three groups conducted the mentioned test again at the posttest step. To compare the between-groups data at the posttest, one-way Analysis of Variance (ANOVA) and Least Significant Difference (LSD) test were used to compare the differences between the research groups at a significance level 0.05. Results: The present research results indicated that the balance and Cawthorne-Cooksey exercises performed in the experimental groups revealed statistically significant changes in the two studied factors (both P=0.001). Moreover, the LSD test results signified that in the mobility test, there was a significant difference between the control group and balance exercises group (P=0.001) and the control group and Cawthorne-Cooksey exercises group (P=0.001). Additionally, in the static balance test, a significant difference was observed between the control group and balance exercises group (P=0.003) and the control group and Cawthorne-Cooksey exercises group (P=0.001). Finally, it was revealed that female patients with MS presented better balance and mobility after performing the exercise sessions. Conclusion: The obtained data suggested that specialists could use the explored selected balance exercises and Cawthorne-Cooksey exercises to improve balance and mobility in patients with MS.

The purpose of this research is to examine the effects of imagination and cognitive learning exercises, which are applied to increase the success of elite handball players, on their balance skills.The research group consists of a total of 36 voluntary male athletes, 18 of which are the control group and 18 of them are the experimental group, aged between 14 and 16, with at least 5 years of sports experience, who have been playing handball in Kayseri Youth Sports Club. For the study group, 8-day, 30-minute cognitive training and imagination study program was applied as two sets per day. No exercise was applied to the control group. Static and dynamic balance tests were applied to all of the participants (study and control group at the beginning and end of the study. According to the results of the analysis performed at the end of the study, a significant difference was found between the post-test results of all balance parameters of the experimental and control groups (p <0.05). When the pre-test and post-test results of the control group were compared, there was a significant difference between the scores of Static, Level8, Level4 and Oscillation CE (p<0.05) and there was no significant difference between Level2 and Oscillation OE (p>0.05). When the pre-test and post-test results of the experimental group were compared, a significant difference was found between all equilibrium parameters (p<0.05).As the result, it was found that cognitive imagination programs have positive effects on learning the balance skills in handball players under the light of the obtained findings.

Full textAbstract:
Abstract Background The Mini-Balance Evaluation Systems Test (Mini-BESTest) is a clinical balance test comprising 14 items assumed to reflect the unidimensional construct “dynamic balance.” Objective The study objective was to examine the dimensionality of the test and the properties of each item and their interrelationships in elderly people with mild to moderate Parkinson disease (PD). Design This was a cross-sectional study in a laboratory setting. Methods A total of 112 participants (mean age=73 years) with idiopathic PD (Hoehn and Yahr stages 1–3) were assessed by physical therapists. Local independence among items was examined with Rasch modeling. Unidimensionality was tested by running a principal component analysis on the residuals. An exploratory factor analysis was used to examine the structure of the test, and a confirmatory factor analysis was used to evaluate the fit of the derived model. Results The first residual component of the principal component analysis, with an eigenvalue of greater than 2, superseded the assumption of unidimensionality. After the omission of item 7 because of convergence problems, the exploratory factor analysis suggested that a 3-factor solution best fit the data. A confirmatory factor analysis demonstrated acceptable fit of the final model, although item 14 loaded poorly on its factor. Limitations The sample size was on the lower end of what is generally recommended. Conclusions This study could not confirm that the Mini-BESTest is unidimensional. Gait items were dispersed over all factors, indicating that they may reflect different constructs. Nonetheless, as there arguably is no clinical balance test superior to the Mini-BESTest today, we recommend using the total score for assessing gross balance in this population and individual items to identify specific weaknesses. Moreover, dual tasks should be assessed separately because they are an important aspect of balance control in people with PD, reflected in only one item of the test.

Full textAbstract:
Background: Losses in lower extremity muscle strength/power, muscle mass and deficits in static and particularly dynamic balance due to aging are associated with impaired functional performance and an increased fall risk. It has been shown that the combination of balance and strength training (BST) mitigates these age-related deficits. However, it is unresolved whether supervised versus unsupervised BST is equally effective in improving muscle power and balance in older adults. Objective: This study examined the impact of a 12-week BST program followed by 12 weeks of detraining on measures of balance and muscle power in healthy older adults enrolled in supervised (SUP) or unsupervised (UNSUP) training. Methods: Sixty-six older adults (men: 25, women: 41; age 73 ± 4 years) were randomly assigned to a SUP group (2/week supervised training, 1/week unsupervised training; n = 22), an UNSUP group (3/week unsupervised training; n = 22) or a passive control group (CON; n = 22). Static (i.e., Romberg Test) and dynamic (i.e., 10-meter walk test) steady-state, proactive (i.e., Timed Up and Go Test, Functional Reach Test), and reactive balance (e.g., Push and Release Test), as well as lower extremity muscle power (i.e., Chair Stand Test; Stair Ascent and Descent Test) were tested before and after the active training phase as well as after detraining. Results: Adherence rates to training were 92% for SUP and 97% for UNSUP. BST resulted in significant group × time interactions. Post hoc analyses showed, among others, significant training-related improvements for the Romberg Test, stride velocity, Timed Up and Go Test, and Chair Stand Test in favor of the SUP group. Following detraining, significantly enhanced performances (compared to baseline) were still present in 13 variables for the SUP group and in 10 variables for the UNSUP group. Conclusion: Twelve weeks of BST proved to be safe (no training-related injuries) and feasible (high attendance rates of >90%). Deficits of balance and lower extremity muscle power can be mitigated by BST in healthy older adults. Additionally, supervised as compared to unsupervised BST was more effective. Thus, it is recommended to counteract intrinsic fall risk factors by applying supervised BST programs for older adults.

This paper presents a new rotordynamic measurements conducted on a test rig for evaluation of multiple rings of labyrinth seals. Considering the tilting motion of cylinder occurs in experiments, the impedance matrix of cylinder system is obtained first. An equivalent seal force identification model is set up for multiple seals based on double plane balance theory of rotor dynamics. The resultant seal forces are calculated on two end planes of the cylinder, and resolved to multiple sections that seals located. A frequency domain identification method delivers the test seals stiffness and damping coefficients. Compressed air inlet tests were run from 1000 rpm-2200rpm, 0.1-0.6Mpa supply pressures were used. For each ΔP test condition, the static eccentricity ratio ε=e/Cr is range from zero to approximately 0.6. Results show that 8 rotordynamic coefficients increase almost linearly with inlet/outlet pressure ratio. Increasing eccentricity ratio weakens the stability of seal-rotor system obviously.

Abstract This study aims to identify if there is a relation between postural balance and the accuracy of 7 meters throws in handball. There is an increase need to improve the success of the 7 meters throw, due to its impact regarding a win or loss over the past years during high-end competitions. Subjects: 173 subjects were involved in this study, 123 males and 50 females with the ages between 18 and 21 years old. Materials: We’ve conducted the balance test using the AMTI NETforce BP 400600 force platform and for the accuracy test we’ve conducted a shooting trial that quantified the spread of a series of throws from the 7 meters mark. We’ve observed the radial dislocation, area and length of the center of pressure for the balance test and for the shooting trial we’ve measured the distance of the throw from a preset spot. Results: There were no correlation between the important factors of balance like Dislocation, Area, Length, and throwing percentage for the Circle, Area 1, Area 2, Missed balls. Instead, between the 3 important factors of balance, there are strong and positive correlations, drawing the conclusion that when we have big numbers for center of gravity deviations, total trajectory (cm2) and the area values, the chances to score a goal from 7 meters are lower. Conclusions: The results of the study confirm the hypothesis. The objectives for a future study is to find ways/methods to improve the general balance, in order to increase the efficiency for the 7 meters throwing.

Full textAbstract:
Previous studies measured flow states using students’ self-reported experiences, resulting in issues regarding nonobjective and nonreal-time data. Thus, this study used an electroencephalogram (EEG) to measure the EEG-detected real-time flow states (EEG-Fs) of 30 students from the 4th and 5th grades. Their EEG measurements, self-reported reflective flow experiences (SR-Fs), grade levels (GLs), balance of challenge and skill (BCS), and sense of control, represented by their overall test performance (OA-tp) and momentary test performance (MOM-tp), were analyzed to establish their EEG-F’s construct. Based on the results of a chi-square test, the EEG-F correlates significantly with SR-F, BCS, OA-tp, and MOM-tp. A J48 decision tree analysis and logistic regression further revealed that in-flow experiences (in-EEG-F) were detected when students had high SR-Fs, where the BCS contributed to flow states. In particular, students with a low-challenge/high-skill BCS demonstrated an in-EEG-F state upon having a high OA-tp. For high-challenge/high-skill, the in-EEG-F state was determined through their MOM-tp. Through the EEG and flow state construct, this study revealed a whole-part association between students’ momentary and overall reflective flow experiences and identified viable paths for inducing students’ EEG-Fs, which can contribute to future e-learning development when integrated with a brain-computer interface for e-learning or e-evaluation systems.

Abstract Alterations in balance and gait are frequently present in patients with hemiparesis. This study aimed at determining whether there is a correlation between static and functional balance, gait speed and walking capacity. To that end, 17 individuals with chronic hemiparesis of both sexes (58.8% men and 42.25 women), mean age of 56.3 ± 9.73 years, took part in the study. Static balance was assessed by computerized baropodometry, under two different sensory conditions: eyes open (EO) and eyes closed (EC). Functional balance was evaluated by Berg Balance Scale and walking ability by the Functional Ambulation Classification. Gait speed was assessed by kinemetry. The Kolmogorov-Smirnov test was used to verify data distribution normality. Parametric variables were correlated by Pearson's test and their non-parametric parameters by Spearman's test. Functional balance showed a positive correlation with gait speed (p=0.005; r=0.64) and walking ability (p = 0.019; r = 0.56). Anteroposterior (AP) and mediolateral (ML) alterations with EO and EC exhibited negative correlations with gait speed (EO: AP amplitude (p = 0.0049 and r = -0.48); mean ML deviation (p = 0.019 and r =-0.56)/ EC: mean AP deviation (p = 0.018 and r = -0.56) and mean ML deviation (p = 0.032 and r = -0.52); AP amplitude (p = 0.014 and r = -0.57) and ML amplitude (p = 0.032 and r = -0.52); postural instability (p = 0.019 and r = -0.55)) and walking ability (EO: mean AP deviation (p = 0.05 and r = -0.47) and AP amplitude (p = 0.024 and r = -0.54)). The results suggest correlations between static and functional balance and gait speed and walking ability, and that balance training can be an important component of gait recovery protocols.
