wrist extension

Having a minimum of 20 degrees of active wrist extension and 10 degrees of finger extension .

手腕能主动背伸至少20°，除拇指外，至少有其他两指背伸10°。

EMG amplitude , Muscle strength and ROM of wrist extension were measured before and after treatment every time .

腕背伸时肌肉最大收缩时肌电幅值，伸腕主动关节活动范围，腕伸肌力于每次治疗前后均给予测评并记录。

Comparison of Effect of Reconstruction of Wrist Extension and Finger Extension with That of Finger Extension in Cases of Irreparable Brachial Plexus Injury

不可逆臂丛神经损伤腕指功能重建伸腕伸指重建与单纯伸指重建比较

Results When wrist extension simulated , the amplitude of action potential waveform of radial nerve was higher than that of median and ulnar nerve .

结果模拟腕伸时桡神经电位波幅较正中神经和尺神经高。

The function of elbow flexion , wrist extension , and MCP joint extension reached preoperative level . One year follow-up showed remarkable improvement in all assessed functions ( P < 0.05 ) .

术后1年肩外展、屈肘、伸腕和伸掌指关节功能明显优于术前（P<0.01）。

However , the fixation in wrist dorsal extension benefits to the improvment of the finger swelling , the avoidence of the complication of carpal tunnel syndrome , and the functional recovery in senile patients .

但腕背伸位固定有利于改善手部肿胀，有利于老年患者功能恢复，并能避免腕管综合征的发生。

Experimental study of full length phrenic nerve transfer for restoration of wrist and finger extension

全长膈神经移位恢复伸腕指功能的实验研究

When operating in the line of wrist flexion and extension axis to produce subcutaneous treatment of shock .

操作时以腕关节为轴行屈伸运动从而产生治疗部位皮下的震动。

Objective To evaluate the effect of full length phrenic nerve transfer to different portion of the radial nerve for restoration of wrist and finger extension .

目的比较全长膈神经移位至上臂段桡神经前臂支不同部分恢复伸腕、指功能的效果。

Conclusion The treatment outcome of transferring full length phrenic nerve to the medial portion of the radial nerve is superior in restoring wrist and finger extension .

结论经胸切取全长膈神经移位至上臂段桡神经内侧部分能更全面的恢复伸腕、指功能。

Conclusions : During planar wrist flexion and extension , the ranges of motion of the proximal row of carpal bones are significantly different from each other .

结论：腕关节屈伸运动时，近侧列腕骨的角度相差很大，其中舟骨屈伸角度最大，三角骨次之，月骨角度最小。

Conclusions Arthrodesis of radius and proximal row carpal bones impaired wrist flexion and extension most significantly . Ulnar and radial deviation of the wrist reduced most significantly after fusion of mid intercarpal joint .

结论近排腕骨与桡骨融合术对腕关节屈伸影响最大，远近排腕骨融合术对尺桡偏影响最大。

This paper describes the spectrum analysis of muscular-electric signals produced by wrist extensor and flexor of normal persons during finger extension and flexion , wrist extension and flexion , as well as turning in and out of the wrist .

本文利用7T08信号处理仪对健康人的腕伸肌和腕屈肌在指伸、指屈、腕伸、腕屈、旋前，旋后六个动作下所发出的肌电信号一一作了频谱分析。
