踝阵挛(ankle clonus)是一种病理反射。检查时嘱患者仰卧,髋关节与膝关节稍屈,一手持患者小腿,另一手持住患者足的远端,用力使踝关节背屈,则踝关节呈节律性伸屈运动,超过3次为异常。一般见于锥体束损伤,也可见于中枢神经系统兴奋性亢进和神经官能症。治疗针对原发病进行。
目的:探讨踝阵挛试验在脊柱侧凸手术治疗中的应用价值。
Objective: To evaluate the application value of the ankle clonus test in surgeries of scoliosis.
目的:探讨踝阵挛试验在脊柱侧凸矫形手术中脊髓功能监测的应用价值。
Objective: to evaluate the ankle clonus test for the monitoring of the spinal cord function during corrective surgery of scoliosis.
因此在本观察中,踝阵挛试验无真阳性和假阴性结果,4例假阳性结果(8.16 % )。
Therefore, the ankle clonus test had no false-negative or true-positive result and 4 false-positive results(8.16%).
