上肢体感诱发电位对颈髓损伤的评估价值

The value of somatosensory evoked potentials in evaluation of patients with cervical spinal cord injury

目的 探讨上肢体感诱发电位 (SEP)在颈髓损伤功能评定中的价值。方法 对 3 6例颈髓损伤患者在综合康复治疗前后采用 40分法评定脊髓功能并行上肢SEP检查 ,对照分析SEP与颈髓损伤的功能及疗效评定之间的关系。结果 ① 3 6例颈髓损伤患者治疗前SEP异常率为 86.1%。②与对照组相比 ,疾病组治疗前N11、N13 及N2 0 的潜伏期较对照组延长 (P <0 .0 5 ) ,治疗后有明显改善 (P <0 .0 5 )。③治疗前后SEP检测异常患者的颈椎脊髓功能评分均明显低于SEP检测正常的患者 (P <0 .0 5 )。结论 上肢SEP可作为颈髓损伤功能及疗效评定的依据 ,N11及N13

Objective To study the validity of upper limb somatosensory evoked potentials (SEPs) in functional evaluation of patients with cervical spinal cord injury. Methods Thirty six cases of cervical spinal cord injury were examined by SEP and assessed with a 40 point scale for cervical cord function before and after comprehensive rehabilitation treatment. The relationship among the SEPs and therapeutic effects and the results of function assessment of these patients were analysed. Results ① The abnormal rate of SEP was 86.1% before treatment, and the main abnormanities SEPs were the delay of latency. ② Compared with the control group, the latency in treatment group was markedly delayed ( P <0.05). Though the delayed latency was improved after treatment, it was still abnormal yet. ③ The scores of functional assessment of patients with abnormal SEP was distinctly lower than that with normal SEP both before and after treatment ( P <0.05). Conclusion SEP can provide useful information for the evaluation of treatment effect and functional recovery in patients with cervical spinal cord injury.
