目的:探讨脊髓延髓性肌萎缩症(SBMA)的电生理特点。方法:总结并回顾分析了7例SBMA患者的神经传导和针极肌电图的特点,并以肌萎缩侧索硬化(ALS)患者作为对照组,与SBMA组进行比较。结果:(1)SBMA组复合肌肉动作电位(CMAP)异常的患者和神经的出现率均明显低于ALS组(P<0.01)。(2)7例SBMA患者均存在感觉神经传导异常,且上肢感觉神经动作电位(SNAP)异常的出现率高于下肢(P<0.05)。(3)SBMA组自主电位的出现率显著低于ALS组,而巨大电位的出现率显著高于ALS组(P<0.01)。结论:SBMA的神经肌肉电生理改变具有特征性,可以作为鉴别诊断的重要依据。
目的:探討脊髓延髓性肌萎縮癥(SBMA)的電生理特點。方法:總結併迴顧分析瞭7例SBMA患者的神經傳導和針極肌電圖的特點,併以肌萎縮側索硬化(ALS)患者作為對照組,與SBMA組進行比較。結果:(1)SBMA組複閤肌肉動作電位(CMAP)異常的患者和神經的齣現率均明顯低于ALS組(P<0.01)。(2)7例SBMA患者均存在感覺神經傳導異常,且上肢感覺神經動作電位(SNAP)異常的齣現率高于下肢(P<0.05)。(3)SBMA組自主電位的齣現率顯著低于ALS組,而巨大電位的齣現率顯著高于ALS組(P<0.01)。結論:SBMA的神經肌肉電生理改變具有特徵性,可以作為鑒彆診斷的重要依據。

To observe the electrophysiological characteristics of spinal-bulbar muscular atrophy (SBMA). Method:7 cases of SBMA were observed and analyzed on their nerve conduction studies and needle EMG retrospectively.The SBMA cases were taken as test group and ALS patients were taken as control.Result:(1)Incidence of abnormal amplitudes of compound muscle action potentials(CMAPs)was lower in SBMA group than that in ALS cases with statistical significance.(2)All of 7 SBMA patients presented abnormal sensory conduction. Among them,abnormalities of sensory nerve action potential(SNAP)in upper limbs were higher than in lower limbs(P<0.05).(3)Spontaneous activities were less often seen in SBMA cases than in ALS cases,while motor unit action potentials with large amplitude (>5 mV)were more often in SBMA group(P<0.01). Conclusion:The electrophysiological feature of SBMA may help the diagnosis and differential diagnosis in clinical practice.
