Abstract:

Background Little is known about changes in scaphoid and lunate supination and pronation following scapholunate interosseous ligament (SLIL) injury. Information on these changes may help explain why some SLIL reconstructions have failed and help in the development of new techniques. Purpose To determine if following simulated SLIL injury there was an increase in scaphoid pronation and lunate supination and to determine if concurrently there was an increase in the extensor carpi ulnaris (ECU) force. Materials and Methods Scaphoid and lunate motion were measured before and after sectioning of th

Abstract:

The supermarket industry has one of the highest numbers of repeated trauma illnesses. Checkout departments have a rate of musculoskeletal injuries 2 to 3 times higher than that of other supermarket departments. The primary objective of this study was to quantify the wrist motions required to bag groceries using a wrist motion monitor. The wrist motions included deviations, velocities, and accelerations for flexion-extension, radial-ulnar, and pronation-supination directions. The independent variables were handle type and object location. Objects with finger-thumb couplings required more extrem

Abstract:

The dorsal and palmar distal radio-ulnar ligaments (DRUL) play an important role in the stability of the distal radio-ulnar joint (DRUJ). Various authorities, however, hold opposite opinions regarding DRUL motion during DRUJ pronation and supination, thus implying opposite techniques for reconstruction of the unstable DRUJ. With the hypothesis that relative displacement would increase in the dorsal DRUL during pronation and would increase in the palmar DRUL during supination, measurements were made of the relative DRUL displacement with a Hall-effect displacement transducer during DRUJ pronati

Abstract:

Malunion is a common complication of distal radius fracture and often causes a reduction in the range of motion. The measurement of the range of motion is a part of the process for evaluating the final motion after a malunion of a distal radius fracture is diagnosed. However, the amount of range of motion reduced due to the malunion often is calculated upon the assumption that the motion is equal in both forearms. Although this assumption has been questioned, not much work has been conducted which defines the difference in range of motion between the two forearms. In this work, a methodology h

Abstract:

The pronation/supination of the forearm are important movements to properly accomplish the activities of daily living. While several exoskeletons have been proposed for the rehabilitation of the arm, few of them have actively implemented the movements of pronation/supination. Often, the addition of this degree of freedom to the mechanism results in a bulky and heavy structure. Consequently, the overall exoskeleton is too big for a wearable solution. This paper proposes a digital prototype and kinematic evaluation of a cable-driven orthosis for pronation/supination movement assistance. The actu

Abstract:

This study aimed to find an optimal measurement protocol of elbow and forearm kinematics using different modelling and tracking methods. Kinematic data of elbow flexion/extension and forearm pronation/supination was acquired using optical motion capture from 12 healthy male volunteers. Segment coordinate systems for humerus, forearm, radius, ulna, and hand were defined. Different tracking methods, using anatomical markers or rigid or point maker clusters, were used to compute the three-dimensional rotations. Marker placement errors were assessed to evaluate the rigid body assumption. Multiple

Abstract:

Loss of muscle functions, such as the elbow, can affect the quality of life of a person. This research is aimed at developing an affordable two DOF soft elbow exoskeleton incorporating a dual motor-tendon actuator. The soft elbow exoskeleton can be used to assist two DOF motions of the upper limb, especially elbow and wrist movements. The exoskeleton is developed using fabric for the convenience purpose of the user. The dual motor-tendon actuator subsystem employs two DC motors coupled with lead-to-screw converting motion from angular into linear motion. The output is connected to the upper ar

Objectives: The anterior bundle of the ulnar collateral ligament (UCL) is the primary static valgus restraint of the elbow joint. In general, the effect of forearm supination and pronation on native and reconstructed UCL strain is poorly characterized. Specifically, the effect of placing the forearm in supination versus pronation during final graft tensioning at the time of UCL reconstruction has not been quantified. Therefore, the objectives of the current study were the following: 1) to determine the effect of forearm pronation and supination on medial elbow joint gapping with an intact nati

Abstract:

In order to minimize the risk of repetitive trauma injuries, postures or motions that place joints near the limits of their range of motion (RoM) should be avoided. Before it can be determined that a posture or motion approaches the limit of a joint's motion, these limits need to be established. Previous research on wrist functionality has focused almost entirely on RoM in two or three isolated planes (flexion/extension, radial/ulnar deviation, and forearm pronation/supination), without investigating potential effects of complex wrist/forearm posture on RoM.

This paper presents the current state of research into power-assist exoskeletons for the upper limb. The assist of the upper limb is important for physically weak persons in daily activities, since upper-limb motion is involved in many important motions in daily living. The most important criterion is that power-assist exoskeletons assist the user's motion automatically in accordance with the user's motion intentions. Electromyogram (EMG) signals in which the user's motion intention is reflected could provide vital real-time information to facilitate accurate control of the power-assist exoske

Poststroke and traumatic elbow injuries are the most common cause of elbow stiffness, which results in loss of functional range of motion (ROM). Various studies support early mobilization of the elbow joint after injury or after surgery to reduce risks of elbow stiffness development. After hospitalization, patients are required to follow a long-term rehabilitation program during home recovery. Still, most patients do not adhere to their clinical therapy schedule due to either rehabilitation cost, social obligations, negligence, or lack of inspiration.

A sound knowledge of the elbow anatomy and biomechanics is critical to understanding the pathology of various elbow disorders and instigating appropriate management. The elbow joint is a trochoginglymoid joint: that is, it has flexion-extension [ginglymoid] motion at the ulnohumeral and radiocapitellar articulations and pronation and supination [trochoid] motion at the proximal radioulnar joint. Stability of the elbow joint is achieved through static and dynamic components.
