Prevention of Tendon Subluxation in Dequervain's Tenosynovitis Release Using Retinacular Repair.

This study compared the incidence of tendon subluxation in patients of a single surgeon undergoing Dequervain's release with and without retinacular repair. The study reviewed 31 patients that underwent standard Dequervain's release without retinacular repair and 49 that underwent Dequervain's release with retinacular repair. Each subject's functional status was assessed using the Patient-Rated Wrist/Hand Evaluation.

Activation of rectus capitis posterior major muscles during voluntary retraction of the head in asymptomatic subjects.

Objective: The purpose of this study was to assess levels of electromyographic activity measured from rectus capitis posterior major (RCPM) muscles of asymptomatic subjects as their heads moved from a self-defined neutral position to a retracted position.

Methods: A 2 × 2 within-subjects factorial research design was used. Disposable, intramuscular electrodes were used to collect electromyographic data from asymptomatic subjects between the ages of 20 and 40 years old.

Repetitive stress and strain injuries: preventive exercises for the musician.

There are many articles that support stretching, strengthening, good nutrition, hydration, rest, and ergonomics along with many other concepts that may be helpful in preventing repetitive stress injuries. The most conclusive literature proposes early recognition of onset symptoms, and immediate reduction or cessation of the casual activity. This is not well accepted by the musician, because this means an interruption of practice and performance.

Effect of occupational keyboard typing on magnetic resonance imaging of the median nerve in subjects with and without symptoms of carpal tunnel syndrome.

Objective: To examine the effects of occupational keyboard typing on median nerve shape and T2 relaxation and on forearm muscle T2 in professional typists with and without symptoms of carpal tunnel syndrome.

Design: Based on the Levine Carpal Tunnel Syndrome Symptom Severity scale (LCTSS), 12 female professional typist volunteers were divided into asymptomatic (LCTSS < 1.3, n = 5) and symptomatic (LCTSS > 1.
