| Research Abstract |
In the isometric wrist dorsiflexion task, the wrist extensor muscles were influenced by forearm and wrist position. The extensor carpi radialis longus and brevis activities were significantly higher in forearm pronation and the extensor carpi ulnaris were in supination. The differences of muscle activities due to forearm position were more remarkable than that due to wrist position. In the cylindrical grasp task, all wrist extensor muscles were significantly higher in forearm pronation. The characteristic of activities between flexor digitrum profundus and superficialis was difference during cylindrical grasp, but both muscle activities were not affected by forearm position. In addition, the forearm position contributes to the excitability of corticospinal neurons at cortical level in the wrist extensor muscles.
