强度时间曲线在腰椎间盘突出症康复评定中的应用价值

The application significance of intensity/time curves on the evaluation of operation on prolapsed lumbar intervertebral disc

目的 :探讨强度时间曲线在腰椎间盘突出症康复评定中的应用价值。方法 :测定 111例患者胫前肌、腓骨长肌、拇长伸肌的强度时间曲线共 2 44条 ,其中 5 6例行手术治疗。结果 :111例患者 ,正常 2 4例 ,部分变性 83例 ,部分—完全变性 4例 ,阳性率为 78.38% ;手术的 5 6例患者I/T曲线 :部分—完全变性 4例 ,部分变性 45例 ,正常 7例 ,与手术符合率为 87.5 %。共检测的 2 44条I/T曲线中 ,正常曲线 115条 ,部分变性 12 5条 ,完全变性 4条 ,阳性率为 5 2 .0 7% ;患者的阳性率与所检查的肌肉数成正比 ;正常和失神经支配的基强度、时值、利用时比较 ,基强度的P >0 .0 5 ,时值和利用时的P <0 .0 5。结论

Objective: In order to discuss the application value of intensity/time(I/T) curves on the rehabilitation assessment of prolapsed lumbar intervertebral disc. Method: 244 I/T curves of 111 cases including musculus tibialis anterior、musculus fibularis longus、musculus extensor hallucis longus were measured. 56 cases were operated. Result: In the 111cases, 24cases were normal, 83 cases were partial degeneration, 4 cases were complete degeneration, the positive ratio was 78.38%. The I/T curves in 56 operated cases, 4 cases were complete degeneration, 45 cases were partial degeneration, 7 cases were normal. In 87.50% cases the I/T curve accorded with operation. In 244 I/T curves, 115 curves were normal, 125 curves were partial degeneration, 4 curves were complete degeneration. The positive ratio were 52.05%. Conclusion: The application value of I/T curves was significant on the rehabilitation assessment of prolapsed lumbar intervertebral disc.
