OBJECTIVES The aim of this study was to measure the degree of movement of the ulnar nerve in the cubital tunnel using sonography in patients with ulnar neuropathy at the elbow compared to a healthy control group. METHODS We examined the ulnar nerve in the cubital tunnel using sonography with the elbow extended and then flexed in 26 patients with ulnar neuropathy and 13 control participants. T...

Twenty-nine normal adults were tested to measure the electrical activity of the anterior, middle, and posterior portions of the deltoid muscle and sternal portion of the pectoralis major muscle during the performance of four upper extremity diagonal patterns with the elbow straight, flexing, and extending. The patterns were performed through range of motion, with an isometric contraction perfor...

BACKGROUND The use of different coordinate system definitions for the patella leads to difficulties in comparing kinematic results between studies. The purpose of this work was to establish the effect of using a range of coordinate system definitions to quantify patellar kinematics. Additionally, intra- and inter-investigator repeatabilities of the digitization of anatomic landmarks on the pate...

We proposed and implemented a system based on fuzzy logic Toolbox. designed such to measure the strength of upper limb elbow tennis player. have tried predict injuries movements for sports player, For that we used Triangle Trapezoidal membership function better prediction strength. selected Two input parameters Elbow Flexion Angle Torque in development using toolbox Matlab. considered these two...

Significant excursion of the ulnar nerve is required for unimpeded upper extremity motion. This study evaluated the excursion necessary to accommodate common motions of daily living and associated strain on the ulnar nerve. The 2 most common sites of nerve entrapment, the cubital tunnel and the entrance of Guyon's canal, were studied. Five fresh-frozen, thawed transthoracic cadaver specimens (1...

The expression of MuRF1 and MAFbx in a denervated muscle has previously been studied. However, the expression of MuRF1 and MAFbx in the recipient and donor muscles after muscle transfer for reconstruction of joint function has not been sufficiently investigated. Forty-two adult Sprague-Dawley rats were divided into 7 groups: normal, 1 w post-, 2 w post-, and 4 w post-musculocutaneous nerve tran...

The purpose of this study was to examine the influence of neutral and pronated handgrip positions on corticospinal excitability to the biceps brachii during arm cycling. Corticospinal and spinal excitability were assessed using motor evoked potentials (MEPs) elicited via transcranial magnetic stimulation (TMS) and cervicomedullary-evoked potentials (CMEPs) elicited via transmastoid electrical s...

We have treated 22 patients with an elbow contracture using a static progressive turnbuckle splint for a mean of 4.5 +/- 1.8 months. All had failed to improve with supervised physiotherapy and splinting. The mean range of flexion before splintage was from 32 +/- 10 degrees to 108 +/- 19 degrees and afterwards from 26 + 10 (p = 0.02) to 127 +/- 12 degrees (p = 0.0001). A total of 11 patients gai...
