Introduction Sustained, repetitive, prehensile activities that require precision and stability, necessitate a sustained static shoulder girdle posture over long periods of time, which can result in abnormal activation the musculature consequent scapular misalignments. Aim, Aim this study was to establish test-retest inter-tester reliability six (6) clinical tests commonly used measure parameter...

We investigated how repetitive hand activity normally affects carpal tunnel pressure and whether a flexible wrist splint can influence this effect. Nineteen healthy subjects were evaluated under four test conditions: at rest with and without a wrist splint (baseline) and while performing a repetitive task with and without a wrist splint. The task involved loading and unloading 1 lb. cans from a...

INTRODUCTION Handrim wheelchair propulsion is a mechanically inefficient mode of locomotion in comparison to arm cranking and cycling (de Groot et al., 2002). In addition, wheelchair propulsion has been associated with high physical strain and repetitive strain injuries (Janssen et al., 1994). The inefficiency of wheelchair propulsion has been attributed to factors such as, improper fit of the ...

In general, people who perform repetitive motions are often vulnerable to repetitive strain injuries. Because musicians must execute the same motion over and over again while practicing and performing their music, they are an example of a group that often develops these repetitive strain injuries. More specifically, musicians are known for developing neuropathies in their upper limbs, with carp...

Osteoarthritis (OA) is a major musculoskeletal disorder which causes are not always fully understood. Femoroacetabular impingements such as cam/ pincer cannot always explain observed OA in hips with normal morphology. This paper investigates the hypothesis of extreme repetitive movements as a source of cartilage degeneration. We present a clinical study conducted with professional ballet dancer...
