目的:通过对脑卒中后患者上肢神经电生理的分析,探讨臂丛神经损伤和临床表现之间的关系。方法:选择符合入组条件的脑卒中患者59例,根据其肩关节疼痛的视觉模拟评分法(Visual Analogue Scale/Score,VAS)分为肩痛组(35例)和无肩痛组(24例)。测定59例患者进行上肢运动、感觉神经传导速度及针极肌电图数据,根据结果判定是否存在臂丛神经损伤。结果:59例患者中有29例存在臂丛神经损伤,其中24例为肩痛组患者,其中5例为无肩痛组患者。两组合并臂丛神经损伤的概率具有统计学差异(P<0.05)。结论:卒中后临床表现偏瘫肩痛与臂丛神经损伤具有高度相关性,但无肩痛病人也存在臂丛神经损伤,应用肌电图进行臂丛神经损伤的诊断更加的准确可靠,可提高早期康复干预可能性。
OBJECTIVE: To investigate the relationship between the brachial plexus injury and clinical manifestations by analyzing the electrophysiology of the upper limbs of post-stroke patients. Methods: Fifty-nine stroke patients were selected according to the criteria of visual analogue scale (VAS) of shoulder pain. The patients were divided into shoulder pain group (n = 35) and shoulder painless group (n = 24) ). Fifty-nine patients were evaluated for upper extremity movement, sensory nerve conduction velocity and needle-pole EMG data, and brachial plexus injury was determined based on the results. Results: Of the 59 patients, 29 had brachial plexus injury, of which 24 were shoulder pain patients and 5 were those without shoulder pain. There was a significant difference between the two groups in the probability of brachial plexus injury (P <0.05). Conclusion: The clinical manifestations of post-stroke hemiparesis shoulder pain and brachial plexus injury are highly correlated, but there is also brachial plexus injury in patients without shoulder pain. The diagnosis of brachial plexus injury by electromyography is more accurate and reliable, which can improve the early Rehabilitation intervention possibilities.
