The electromyographic (EMG) signal is used to discriminate eight hand motions: power grasp, hook grasp, wrist flexion, lateral pinch, flattened hand, centralized grip, three-jaw chuck and cylindrical grasp. From the analysis of the PC-based control system, a three-channel EMG signal is used to distinguish eight hand motions for the short below elbow amputee. Pattern recognition is used in this ...

The anatomical structures vulnerable to acupuncture around the PC6 acupuncture point were investigated. Needles were inserted in PC6 of eight wrists from four cadavers to a depth of 2 cm, the forearms were dissected and the adjacent structures around the path of the needles were observed. The needles passed between the tendons of the palmaris longus and flexor carpi radialis muscles and then pe...

Giant cell tumour of the bone (GCT) is a rare locally aggressive primary bone tumour with an incidence of 3% to 5% of all primary bone tumours. The most common location for this tumour is the long bone metaepiphysis especially of the distal femur, proximal tibia, distal radius, and the proximal humerus. Involvement of distal ulna is rare accounting for 0.45% to 3.2%. Considering local aggressiv...

OBJECTIVES To study the impact of tendon transfer surgery for ulnar claw hand correction in children with leprosy. SUBJECTS AND METHODS All the children who underwent reconstructive surgery for ulnar nerve paralysis during the period 2007 to 2012 were included in the study. Unassisted angle, grasp contact, pinch contact and functional assessment were the main outcome measures. All the surgica...

INTRODUCTION Ethnic variations in the prevalence of absence of the palmaris longus (PL) are well known. Many techniques for clinically determining the presence of the PL have been described. Studies have also attempted to correlate its absence with other anatomical anomalies. However, most studies have been done in Caucasian populations. MATERIALS AND METHODS The presence of the PL was clinic...

Coordinated landing requires preparation. Muscles in the limbs important for decelerating the body should be activated prior to impact so that joints may be stiffened and limbs stabilized during landing. Moreover, because landings vary in impact force and timing, muscle recruitment patterns should be modulated accordingly. In toads, which land using their forelimbs, previous work has demonstrat...

We report an unusual case of a rupture of the flexor pollicis longus tendon after two intrasheath triamcinolone injections for left trigger thumb in a 56-year-old woman. Tendon grafting from proximal to the wrist to the fingertip was carried out using the palmaris longus tendon. The clinical result was evaluated as good according to Strickland's criteria. Recently, intrasheath triamcinolone inj...
