Thirty-six digits with an intra-articular fracture of the dorsal aspect of the distal phalanx that involved one-third or more of the articular surface were treated by open reduction and internal fixation with Kirschner wires. After an average length of follow-up of forty-six months, roentgenograms of the distal joint in twenty-six digits appeared essentially normal. Ten digits had minor roentge...

[Purpose] This study verified the changes in muscle activities and grasping power during maximal isometric exercise of the forearm and masseter muscle with and without a mandibular orthopedic repositioning appliance (MORA). It also offers basic data for defining the correlation of function of hand with mouth. [Methods] EMG was used to measure masticatory muscle, flexor bundle and extensor bundl...

BACKGROUND Arthritis at the trapeziometacarpal joint of the thumb is common. Several surgical options exist showing favorable results. We report the outcomes after interposition of allograft knee meniscus for thumb trapeziometacarpal arthritis. METHODS Twenty-three patients (25 thumbs) had surgery for thumb trapeziometacarpal arthritis using knee meniscal allograft tissue. Eleven thumbs had a...

OBJECTIVE To assess changes and responsiveness in outcome measures of mobility, balance, muscle strength and manual dexterity in adults with myotonic dystrophy type 1. DESIGN A 9-year longitudinal study conducted with 113 patients. METHODS The responsiveness of the Timed Up and Go test, Berg Balance Scale, quantitative muscle testing, grip and pinch-grip strength, and Purdue Pegboard Test w...

In this work we present a biomechanical model of the normal and reconstructed human hand. The objective of this model is to predict muscle forces during the following three tasks: tip pinch, key pinch and grasp. The model takes into account all the available tendons in the fingers. Two common tendon transfers, to reconstruct the pathological hands, are then simulated. The brachioradialis BR tra...

BACKGROUND Objective assessment of motor function is frequently used to evaluate outcome after surgical treatment of carpal tunnel syndrome (CTS). However a range of outcome measures are used and there appears to be no consensus on which measure of motor function effectively captures change. The purpose of this systematic review was to identify the methods used to assess motor function in rando...

OBJECTIVE To determine the effect of massed practice (MP) versus massed practice combined with somatosensory stimulation (MP+SS) on cortical plasticity and function in persons with incomplete tetraplegia. METHODS Ten subjects were assigned to either MP or MP+SS. Median nerve stimulation (500 ms train, 10 Hz, 1 ms pulse duration) was delivered at the intensity eliciting a motor threshold respo...
