Methods 22 patients with median nerve injury are compared with 22 healthy controls in terms of distant and near latency, distant and near wave amplitude and MNCV. MP of patients including abductor pollicis brevis, flexor hallucis brevis and opponens pollicis are examined before MNCV tests.

另将22例健康受试者作为对照组，在同条件下进行检查。MNCV测定指标包括：远、近端潜伏期，远、近端波幅，MNCV值。

objective to study the physiological examining behavior of the abductor pollicis brevis r 1 response and measure normative data.

anatomical study of extensor digitorum longus muscle flap variations in the tendons of the insertion of the abductor pollicis longus and extensor pollicis brevis

趾长伸肌瓣的解剖学研究拇长展肌与拇短伸肌肌腱及其抵止的变异

f wave and h reflex were studied in the abductor pollicis brevis. the probability of f wave evoked by single stimulation was 9. 84%. but f wave was canceled by double stimulation.

本试验研究拇短展肌和小指展肌，单个刺激时，观察F波出现率为9.84%，双重刺激时F波消失。

the distance from the point where the most lateral branch of the pin enters the abductor pollicis longus muscle to the lateral margin of the radius ( dsp).

骨间背神经最外侧分支穿拇长展肌处至桡骨外缘的距离（DSP）。

ecu had constant anatomical position, sufficient length and strength. the direction of transferring ecu to epb tendon was consistent with that of abductor pollicis brevis, and the angle of thumb supination was enough to pronate.
