The manipulation mechanism of the giant panda (Ailuropida melanoleuca) was examined by means of CT (computed tomography) and 3-dimensional (3-D) Volume Rendering techniques. In the 3-D images of the giant panda hand, not only the bones but also the muscular system was visualised. Sections of the articulated skeleton were obtained. It was demonstrated that the hand of the panda is equipped with ...
background: two main muscles studied in the hand for evaluation of median nerve injuries are opponens pollicis (op) and abductor pollicis brevis (apb). however, riché-cannieu communicating branch (rccb) may limit the use of these muscles in electrodiagnosis. this condition is confusing in the case of median nerve injuries. this study was conducted to evaluate the prevalence of rccb. methods: ...

BACKGROUND The development of osteoarthritis (OA) in the hand results in increased joint stiffness, which in turn affects the grip strength. The goal of the present study is to theoretically analyze the muscle forces in a thumb in response to the increased joint stiffness. METHODS The thumb was modeled as a linkage system consisting of a trapezium, a metacarpal bone, a proximal and a distal p...

In 1930 Foerster described an operation for restoring opposition of the thumb in cases of paralysis of abductor brevis and opponens pollicis ; a bone graft was inserted between the first two metacarpals to maintain the thumb in palmar abduction and opposition. The method was elaborated by Thompson (1942) and the results in seven cases were reviewed. Both authors were satisfied that the function...
There is increasing evidence of the importance of synchronous activity within the corticospinal system for motor control. We compared oscillatory activity in the primary sensorimotor cortex [EEG of sensorimotor cortex (SMC-EEG)] and a motor neuronal pool [surface electromyogram of opponens pollicis (OP-EMG)], and their coherence in children (4-12 years of age), young adults (20-35 years of age)...
