In a reaching movement, the wrist joint is subject to inertial effects from proximal joint motion. However, precise control of the wrist is important for reaching accuracy. Studies of three-joint arm movements report that the wrist joint moves little during point-to-point reaches, but muscle activities and kinetics have not yet been described across a range of movement directions. We hypothesiz...

OBJECTIVE To assess the personal, physical and psychosocial factors associated with wrist or hand pain in Australian hospital-based nurses. METHODS Wrist or hand pain, associated disability and sickness absence, demographic, occupational, physical, psychosocial and personal factors among nurses working for three hospitals in Melbourne, Australia, were assessed in a cross-sectional study. Fact...

OBJECTIVES This study aims to retrospectively review the short-term surgical outcome of wrist fusion using wrist fusion rod (WFR). PATIENTS AND METHODS Six wrists of four female patients (mean age 56 years; range 51 to 62 years) with advanced stage rheumatoid arthritis of Larsen IV or V were performed total wrist fusion using WFR. Clinical outcome was assessed using a numeric rating scale of ...

OBJECTIVE The present study evaluated the sensitivity, specificity and predictive values of six clinical tests in the diagnosis of carpal tunnel syndrome (CTS). METHODS There were 29 carpal tunnel syndrome (CTS) subjects (mean age 48 years) and 30 control subjects (mean age 45 years). The six clinical tests included Tinel's sign, wrist flexion with fingers extended, wrist flexion with fingers...

Osteoarthritis of the wrist is one of the most common conditions encountered by the orthopaedic surgeon and requires careful analysis and specific indications and rationale for appropriate treatment. Radiographic analysis and surgical approaches for reconstruction of the wrist consist of technical caveats that will improve outcome, including limited wrist fusions, proximal row carpectomy, and t...

Among conventional manual wheelchair (CMW) users, 49% to 63% experience carpal tunnel syndrome (CTS) that is likely induced by large forces transmitted through the wrist and extreme wrist orientations. The ergonomic hand drive mechanism (EHDM) tested in this study has been shown to utilize a more neutral wrist orientation. This study evaluates the use of an EHDM in terms of wrist orientations t...

We hypothesize that there is a correlation between wrist ligament length disorders and wrist mobility disorders. In order to test that, we intend to add ligament length information to the existing wrist bone model developed at Brown. We will model the length of distal and scapholunate ligaments for a set of 18 wrists (9 of them with mobility problems), evaluate these lengths as functions of spe...

BACKGROUND Grip strength after wrist arthrodesis is reported to be significantly less than normal. One of the reasons suggested for this decrease in grip strength is that the arthrodesis was performed in a suboptimal position. However, there is no consensus on the ideal position of wrist fusion. There is a paucity of studies evaluating the effect of various fixed positions of the wrist on grip ...
