为证实用小腿三头肌肌力作为评价大鼠坐骨神经功能恢复的可靠指标，分别于神经损伤或修复后１０天至６个月进行肌力、神经电生理及组织形态学评价。结果显示，小腿三头肌单收缩肌力和强直收缩肌力与各项电生理及组织形态学指标呈正相关，ｒ＝０．９２９～０．９９６（Ｐ＜０．０１～０．００１）。结果表明，用小腿三头肌单收缩肌力和强直收缩肌力评价坐骨神经再生及功能恢复是非常可靠的，值得推广。
In order to verify the use of triceps muscle strength as a reliable indicator of sciatic nerve function recovery in rats, respectively, 10 to 6 months after nerve injury or repair muscle strength, electrophysiological and histological evaluation. The results showed that unilateral triceps muscle contractile strength and tonic muscle strength and electrophysiological and histological indicators were positively correlated, r = 0.929 ~ 0.996 (P <0.01 ~ 0.001). The results show that the use of triceps unilateral muscle contraction strength and tetanic contraction muscle evaluation of sciatic nerve regeneration and functional recovery is very reliable and worth promoting.
