Abstract

Objectives: To document the utility of decremental responses in the repetitive nerve stimulation test (RNS) and spontaneous activities in needle electromyography (EMG) in the trapezius muscle for the diagnosis of amyotrophic lateral sclerosis.

Methods: Subjects were retrospectively identified from our EMG database. Cervical spondylosis was represented as a disease control group. We investigated the sensitivity and specificity of RNS and EMG in the trapezius muscle and those of diagnostic criteria including the Gold Coast criteria (GCC).

Results: We reviewed 120 patients with amyotrophic lateral sclerosis and 17 patients with cervical spondylosis. "RNS or EMG" achieved the highest sensitivity (85%). The specificity was the highest for RNS (94%). Addition of RNS of the deltoid muscle achieved 98% sensitivity in the upper-limb onset amyotrophic lateral sclerosis. The sensitivity of the GCC was very high (88%).

Conclusions: Neurophysiological parameters investigated in this study having close to 100% specificities or sensitivities are useful as complements to the GCC.

重复神经刺激测试和斜方肌针刺肌电图在早期诊断渐冻人症中的实用性。

研究目的记录重复神经刺激试验（RNS）中的递减反应和斜方肌针形肌电图（EMG）中的自发活动对肌萎缩侧索硬化症诊断的实用性：方法：从我们的肌电图数据库中回顾性地确定受试者。颈椎病作为疾病对照组。我们研究了斜方肌RNS和肌电图的敏感性和特异性，以及包括黄金海岸标准（GCC）在内的诊断标准的敏感性和特异性：我们对 120 名肌萎缩性脊髓侧索硬化症患者和 17 名颈椎病患者进行了复查。"RNS或EMG "的灵敏度最高（85%）。RNS的特异性最高（94%）。在上肢肌萎缩性脊髓侧索硬化症患者中，增加三角肌 RNS 的灵敏度为 98%。GCC的灵敏度非常高（88%）：本研究调查的神经电生理参数特异性或敏感性接近 100%，可作为 GCC 的有益补充。
