Twenty-one cases of neuralgic amyotrophy referred for diagnosis and for electromyography were studied. The criteria used for diagnosis included pain, wasting and paralysis of shoulder girdle muscles, the absence of a compressive or traumatic lesion, spontaneous full or partial recovery and electromyographic findings of denervation or reduced numbers of functioning motor units of the muscles involved. Pain was usually sudden in onset and preceded paralysis. The commonest muscles involved were the deltoid, supraspinatus, infraspinatus and biceps. Sensory changes were minimal. Recovery was the rule and repeat electromyogram after full clinical recovery was normal. The common diagnostic difficulties were excluding poliomyelitis in children, trauma in adults and cervical spondylosis in the elderly. The atypical manifestations need to be recognised in this condition, the aetiology of which is unknown in the majority of cases.
对21例因诊断和肌电图检查而转诊的神经性肌萎缩患者进行了研究。诊断标准包括疼痛、肩胛带肌肉萎缩和麻痹、无压迫性或创伤性病变、自发完全或部分恢复以及受累肌肉的失神经支配或功能运动单位数量减少的肌电图表现。疼痛通常起病突然，先于麻痹出现。最常受累的肌肉是三角肌、冈上肌、冈下肌和肱二头肌。感觉变化轻微。恢复是常见情况，临床完全恢复后重复肌电图检查结果正常。常见的诊断困难在于排除儿童的脊髓灰质炎、成人的创伤和老年人的颈椎病。在这种情况下需要认识到非典型表现，其病因在大多数病例中尚不清楚。
