UNLABELLED To examine the effect of a 10-week upper-body resistance training program on bone turnover markers and site-specific bone mineral density (BMD) in the wrist and distal half of the ulna and radius in untrained and healthy young premenopausal women. METHODS Twenty-two subjects (aged 22.1 ± 1.8 years) were randomly assigned to a resistance training (n = 12) or no training control (n =...

PURPOSE This study examined the kinematic differences between a body-powered prosthesis and a biomechatronics prosthesis as a transradial amputee performed activities that involve flexion/extension and supination/pronation of the wrist. METHOD The subject's wrist movements were calculated and compared as he completed a wrist range of motion test involving simulated flexion/extension and supin...

OBJECTIVE This research examines individual differences in the wrist postures adopted during the use of two pointing devices (mouse and trackball). DESIGN A multiple case study of twelve participants was employed. BACKGROUND The use of pointing devices may lead to musculoskeletal discomfort and injury as a consequence of prolonged exposure to postures involving wrist extension and ulnar dev...

CONTEXT Soft-tissue injuries are commonly treated with ice or menthol gels. Few studies have compared the effects of these treatments on blood flow and muscle strength. OBJECTIVE To compare blood flow and muscle strength in the forearm after an application of ice or menthol gel or no treatment. DESIGN Repeated measures design in which blood-flow and muscle-strength data were collected from ...

The wrist is a region that is very vulnerable to injuries of the extremities. Among these injuries, fractures of the pyramidal bone (or triquetrum) in association with dislocation of the hamate and carpal instability are uncommon. They are generally correlated with high-energy trauma and may be associated with neurovascular deficits, muscle-tendon disorders, skin lesions or injuries to other ca...

[Purpose] The aim of the present study was to investigate and compare the effects of whirlpool bath and neuromuscular electrical stimulation on complex regional pain syndrome. [Subjects and Methods] Sixty outpatients (30 per group) with complex regional pain syndrome participated. They received 15 treatment 5 days per week for 3 weeks. The outcome measures were the visual analogue scale for pai...

Background: Avascular necrosis of the lunate or Kienböck‎ disease is a rare disorder with unknown etiology and challenging treatment. Objectives: In this study, we evaluated effects local deferoxamine injection as an angiogenic molecule core decompression to treat disease. Methods: pilot clinical trial, 8 patients stage I IIIA were treated (0.5 mL 500 mg/mL). The outcome measures included wrist...

SUMMARY Stiffness of the wrist can occur following trauma or surgery. In some patients, loss of motion may be refractory to conservative treatment and operative treatment may thus be indicated. The authors report the results and technique of arthroscopic capsular release of the wrist. A cadaveric study was performed to assess the safety of arthroscopic capsular release. Arthroscopic capsular re...

Background and Aims: Scaphoid fractures are the most common fractures of the wrist. This study compared the outcomes of two surgical internal fixation techniques, using either Herbert screws (HS group) or multiple pins (MP group), in the treatment of scaphoid fractures. Methods: This cross-sectional study was performed on 41 patients (23 in HS and 18 in MP groups) with unilateral scaphoid fract...

A two-channel, portable, battery operated, functional electrical stimulation (FES) system with surface electrodes to enhance grasping in tetraplegics was developed and tested. This system is meant for tetraplegics capable of grasping by tenodesis. Candidates for this system must retain some wrist extension, and have paralyzed but innervated finger flexors, and nearly normal shoulder and elbow c...
