周围神经损伤的强度—时间曲线诊断

Strength time curves testing in peripheral nerve injuries

目的 探讨强度-时间曲线诊断法在周围神经损伤康复评定和治疗中的作用。方法 周围神经损伤 118例， 178条神经，进行强度-时间曲线检测。其中 31例 33条神经进行了肌电图和神经传导速度的测定， 16例进行了手术探查， 42例 48条神经进行了动态检测。结果 51例 71条神经 79块肌肉为正常神经支配， 32例 56条神经 59块肌肉为部分失神经支配， 35例 51条神经 53块肌肉为完全失神经支配。结论 强度-时间曲线诊断阳性检出率高，手术符合率好，可动态观察神经损伤和恢复的情况。

Objective To study the effect of strength time curves testing in rehabilitation assessment and treatment for peripheral nerve injurise (PNI).Method One hundred and seventy eight nerves of 118 cases with PNI were measured ,Among of them ,33nerves of 31cases vere tested by EMG and nerve conduction velocity ,16 cases were operated ,48nerves of 42 cases were continuous tested .Result Seventy nine pieces of muscles ,71nerves of 51 cases with PNI were normally innervated ,59pieces of muscles ,56verves of 32cases were partially denervated and 53pieces of muscles ,51nerves of 35 cases were totally denervated .Conclusion The strength time curves testing is sensitive in PNI. The results of examination were consistent with operation ,It can dynamically test the condition of nerve injury and recovery.
