Gravity-compensated extremity joint torque values were measured in approximately 1,000 healthy Japanese to test the hypothesis that young people in Japan have less muscle strength than older people. The extremity joint torque values of the women in their 20s were significantly lower than those of the women in their 40s, 50s, and/or 60s for six extremity joint torque parameters: wrist palmer fle...

PURPOSE Individuals with spinal cord injuries resulting in tetraplegia may receive tendon transfer surgery to restore grasp and pinch function. These procedures often involve rerouting the brachioradialis (Br) and the extensor carpi radialis longus tendons volar to the flexion-extension axis of the wrist, leaving the extensor carpi radialis brevis (ECRB) muscle to provide wrist extension streng...

OBJECTIVE : To evaluate functional outcomes of patients submit-ted to proximal row carpectomy for the treatment of wrist arthri-tis. METHODS : This is a retrospective study using wrist motion and grip strenght of patients diagnosed with Kienböck disease and scaphoid non-union surgically treated by this technique. RESULTS : Eleven patients with 2-year follow-up were evaluated. Wrist motion (...

BACKGROUND In patients who have an injury of the cervical spinal cord, the brachioradialis tendon may be transferred to the extensor carpi radialis brevis tendon to restore voluntary wrist extension. We hypothesized that the active range of motion of the wrist depends on the position of the elbow after this transfer because the brachioradialis changes length substantially during elbow flexion, ...

The aims of this study were to analyze the relationship between maximum isometric strength levels in different upper and lower limb joints and serve velocity in competitive tennis players as well as to develop a prediction model based on this information. Twelve male competitive tennis players (mean ± SD; age: 17.2 ± 1.0 years; body height: 180.1 ± 6.2 cm; body mass: 71.9 ± 5.6 kg) were tested ...

background: to evaluate the intermediate-term outcomes of radius shortening as a treatment for kienbock’s disease. materials and methods: in a historical cohort, 16 skeletally mature patients (9 men and 7 women) with kienbock disease, who were treated with radial shortening osteotomy between 2002 and 2012, were reviewed in our study. the mean age of our patients was 30 (range 18-43) years old. ...

Background: Displaced fractures of radius and ulna bones in adults are usually treated with open reduction and internal fixation. The purpose of this research was to access functional outcome of these fractures. Materials and Methods: In this research 52 Patients who underwent ORIF with DCP 3.5 in past 5 years were investigated. Post-operation protocol was one week immobilization and then acti...

PURPOSE To assess the clinical, radiographic, and functional outcome of treating intra-articular distal radius fractures with fragment-specific fixation. METHODS A retrospective review of 81 patients with 85 intra-articular distal radius fractures who were treated with fragment-specific fixation was performed. Minimum time to follow-up evaluation was 1 year, with a mean time of 32 months. The...

Two treatment approaches used by two hand clinics were compared for patients who had undergone carpal tunnel release surgery. One of the clinics used an exercise program consisting of progressive resistive exercise; the other clinic used limited activity and no specific exercise program. Measurements of grip strength and active and passive wrist flexion and extension were taken 3 weeks and 6 we...

BACKGROUND AND PURPOSE It has been suggested that cyclic neuromuscular electrical stimulation (ES) may enhance motor recovery after stroke. We have investigated the effects of ES of the wrist extensors on impairment of wrist function and on upper-limb disability in patients being rehabilitated after acute stroke. METHODS We recruited 60 hemiparetic patients (mean age, 68 years) 2 to 4 weeks a...
