| 目的：探讨脑卒中患者膈神经电生理功能及吸气功能的变化特征。方法： 对86例脑卒中患者及42例同龄志愿者进行膈神经运动传导及吸气功能检测，分析脑卒中后健、患侧膈神经电生理及吸气功能变化。结果：卒中组较对照组吸气肌力指数、峰值吸气流速、吸气体积均显著下降（P<0.05）；卒中组患侧膈神经运动传导的潜伏期较健侧及对照组延长（P<0.05），健侧与对照组间潜伏期未见明显差异；健侧波幅较患侧及对照组增高（P<0.05），患侧与对照组间波幅未见明显差异；卒中组健、患侧获得最大波幅的最小电刺激强度均较对照组增高（P<0.05）。结论：脑卒中后吸气功能显著下降，患侧膈神经运动传导潜伏期延长伴兴奋性降低；膈神经电生理检测可为脑卒中后膈肌功能评估提供客观依据。 |

| Objective: To investigate the characteristics of electrophysiological changes of phrenic nerve and inspiratory function in patients with stroke. Methods: Phrenic nerve motor conduction and inspiratory function were tested in 42 healthy subjects and 86 patients with stroke. Results: As compared with the control group, the inspiratory strength index, the inspiratory peak velocity and the suction volume decreased significantly in stroke group (P<0.05). The latency of phrenic nerve motor conduction in affected side of stroke group was prolonged obviously as compared with the contralateral side and control group (P<0.05), but there were no significant differences between unaffected side and control group (P>0.05). The amplitudes of phrenic nerve motor conduction in the unaffected side were higher obviously than in the contralateral side and control group (P<0.05), but there were no significant differences between the affected side and control group (P>0.05). The patients with stroke needed greater minimum electrical stimulation intensity to obtain maximum waveform than control group (P<0.05). Conclusions: The inspiratory function decreased significantly poststroke. And the latency of phrenic nerve motor conduction in the affected side is prolonged significantly, and excitability reduced in stroke group. The electrophysiological detection may provide objective evidence for diaphragmatic function evaluation after stroke. |
