background: carpal tunnel syndrome (cts) is one of the most common musculoskeletal disorders among computer users. computer users exhibit various wrist angles while typing. dynamic changes of wrist angle may cause different degrees of median nerve compression. the objective of this study was thus to investigate the effects of the combination of wrist flexion-extension with wrist deviation on me...

Excision of the proximal carpal row has proven over the past 60 years to be an effective technique for certain disorders of the wrist, including degenerative sequelae of scapholunate ligament dissociation and scaphoid nonunions, Kienböck disease, Preisser disease, and other fracture-dislocations of the wrist. The durability of this procedure may be due to remodeling of the capitate head to the ...

BACKGROUND AND PURPOSE Chronic upper extremity hemiparesis is a leading cause of functional disability after stroke. We investigated the hypothesis that bilateral arm training with rhythmic auditory cueing (BATRAC) will improve motor function in the hemiparetic arm of stroke patients. METHODS In this single group pilot study we determined the effects of 6 weeks of BATRAC on 14 patients with c...

This study determined the reliability of muscle function and sensory perception measures of the wrist extensors. The test-retest reliability of the measurements was determined by an intraclass correlation coefficient (ICC), coefficient of variation (CV), standard error of measurements (SEMs), and one-way repeated measures ANOVA using the values collected from 25 young (20.6 +/- 1.3 years) healt...

PURPOSE To evaluate the outcome after single tendon transfer of the flexor carpi ulnaris (FCU) to the digital extensors for high radial nerve palsy. METHODS Records of 10 patients aged 16 to 43 (median, 27) years who underwent single tendon transfer of the FCU to the digital extensors for high radial nerve palsy secondary to closed (n=4) or open (n=4) diaphyseal humeral fractures or deltoid i...

This review describes a series of experiments in which sarcomere length was measured in human wrist muscles to understand their design. Sarcomere length measurements were combined with studies on cadaveric extremities to generate biomechanical models of human wrist function and to provide insights into the mechanism by which wrist strength balance is achieved. Intraoperative measurements of the...

Since wrist-joint position affects finger muscle length and grip strength, we studied its biomechanical relevance in prolonged handwriting. We recruited participants from young adults, aged 18-24, and separated them into control (n=22) and in-pain (n=18) groups, based whether or not they experience pain while handwriting. The participants then performed a writing task for 30 min on a computeriz...

STUDY DESIGN Consecutive case series of patients with C6 and C7 radiculopathies. OBJECTIVES To explore the clinical utility and reliability of manual muscle testing of forearm pronation strength in C6 and C7 radiculopathies. SUMMARY OF BACKGROUND DATA EMG evidence of denervation of the pronator teres was the most common finding in C6 radiculopathies, and frequently present in C7 radiculopat...

Background & Aims: Treatment of osteoporotic distal radius fracture with metaphyseal defect is often complicated by secondary displacement, because of posterior cortex comminution. The aim of this study was to investigate functional outcomes and advantages of injection of bone cement in stabilizing and maintaining this fracture reduction. Methods: This prospective study was performed on 20 ...

Although the outcome of fractures of the distal radius is traditionally assessed using objective clinical variables such as grip strength and range of movement of the wrist, the extent to which they reflect function and outcomes of importance for the patient is uncertain. This may cause considerable inconsistencies in the assessment of outcome using current scoring systems. We prospectively stu...
