Upper extremities musculoskeletal disorders: prevalence and associated ergonomic factors in an electronic assembly factory.

Objectives: To determine the magnitude, distribution and associated ergonomic factors of upper extremities musculoskeletal disorders (UEMSD) among workers of electronic assembly in Thailand.

Material And Methods: This was a cross-sectional study. 591 of 853 workers in an electronic and electrical appliance assembly factory in Bangkok, Thailand, participated in this study.

Early, continuous, passive motion following flexor tendon repair in zone-II: using an originally invented passive motion device.

Objective: To evaluate the invented device for early continuous passive motion with the rehabilitation program of fingers following flexor tendon repair in zone-II and to determine whether early motion of the affected finger can occur without increasing the rates of subsequent tendon rupture.

Material And Method: A quazi experimental study was done between January 2011 and August 2011 by selecting 5 cases with both, flexor digitorum superficialis (FDS) and flexor digitorum profundus (FDP) injuried in zone II of a finger using standard exclusion criteria. The operation was performed by a single surgeon using a standard four-strand repair suture technique and postoperative care consisted of a rehabilitation program with early continuous, passive motion using and original device.
