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.

在等长腕背屈任务中，前臂和腕关节位置对腕伸肌的影响较大。前臂旋前腕长伸肌、腕长伸肌、腕短伸肌活动明显增强，尺侧腕伸肌旋后活动明显增强。前臂位置对肌肉活动的影响比手腕位置对肌肉活动的影响更为显著。在圆柱形抓握任务中，所有腕伸肌在前臂旋前时均显著升高。圆柱形抓握时，指深屈肌和指浅屈肌的活动特征不同，但前臂位置对两者的活动无明显影响。此外，前臂位置有助于腕伸肌皮质水平的皮质脊髓神经元的兴奋性。
