OBJECTIVE To evaluate the activity of wrist extensor muscle, correlating with wrist motion during gripping after flexor tendon repair. DESIGN Cross-sectional clinical measurement study. SETTING Laboratory for biomechanics and rehabilitation. SUBJECTS A total of 11 patients submitted to rehabilitation by early passive motion of the fingers with wrist flexion position were evaluated after 8...

Transfer of the flexor carpi ulnaris (FCU) to replace the power of the paralysed extensor digitorum communis and extensor pollicies longus has been described in the literature. However the use of FCU for strengthening flexor digitorum superficialis (FDS) is relatively not widely known. In this report the use of the technique is dicussed to successfully restore the strength of the fingers of a l...

Background: Despite the growing popularity of bouldering, little is known about degree and variabilityof muscle activation that occurs while solving bouldering problems. The purpose this study was to explorethe electromyography eight upper extremity trunk muscles during a session indoor whilecompleting four different problems.Methods: Eleven climbers with self-reported ability climb V-scale V4 ...

We investigated the electromyographic response to synchronous indirect-localized vibration interventions in international and national table tennis players. Twenty-six male table tennis players, in a standing position, underwent firstly an upper arms maximal voluntary contraction and thereafter two different 30-s vibration interventions in random order: high acceleration load (peak acceleration...

UNLABELLED The purpose of this study was to examine the variability in muscle activity at rest and work during a repetitive task. A total of 20 participants performed a bimanual push task using three frequencies (4, 8, 16 pushes/min), three loads (1 kg, 2 kg, 4 kg) and two grip conditions (no grip, 30% maximum). The coefficient of variation (CoV) of muscle activity was determined for the anteri...

Open dislocation of the proximal interphalangeal (PIP) joint is relatively rare. We report a case of a 32-year-old man who had open dislocation of the PIP joint of the little finger while playing American football. He had a history of chronic radial collateral ligament injury. We reconstructed the radial collateral ligament with a half-slip of the flexor digitorum superficialis tendon.
