肩部肌萎缩性神经痛(NAP)又名Parsonage-Tu-rner 综合征,典型病例表现为:突然起病,肩部昼夜剧烈疼痛经时1～2周,疼痛消失后出现肩部弛缓性麻痹及肌萎缩,特别累及前锯肌、斜方肌、三角肌、岗上及岗下肌、二头肌,6个月至1年完全痊愈,青年男性多见,辅助检查价值不大,脑脊液正常或轻度蛋白质增高,肩部X 片正常,肌电图为神经源性损害。本病疾病分类界限不明确,非典型病例常被排外。本文86例中典型病人66例(男47例,女19例),年龄61～76岁,平均43±16岁。29例有诱因,计疫苗接种7例,耳鼻喉感染5例,肩部外伤7例,外科手术5例。83%以疼痛起病,多位于肩胛或肩胛上方,62%病例疼痛持续8～15天,右侧受累占2/3,萎缩常累及数条肌肉,有的仅1或2条肌肉受累。少见征象有肌束颤、肩周感觉减退,二、三头肌腱反射减弱或消失。67例肌电图有50例提示臂丛轴突性损害,见纤颤电位及高波幅多相运动单位电位, Shoulder Amyotrophic Nephropathy (NAP), also known as Parsonage-Tuner syndrome, typically presents with sudden onset of severe diurnal pain in the shoulders, 1 to 2 weeks after the onset of pain, and subsequent flaccid paralysis And muscle atrophy, especially involving the serratus anterioris, trapezius, deltoid, post and postganglionic muscle, biceps, 6 months to 1 year completely cured, young men more common, less valuable ancillary examination, normal cerebrospinal fluid Or mild protein, shoulder X normal, EMG for neurogenic damage. The classification of the disease disease is not clear, atypical cases often xenophobic. This article 86 cases typical of 66 patients (47 males and 19 females), aged 61 to 76 years, mean 43 ± 16 years. 29 cases of incentives, including vaccination in 7 cases, 5 cases of otolaryngological infection, 7 cases of shoulder trauma, surgery in 5 cases. 83% to the onset of pain, mostly in the shoulder or scapula above, 62% of cases of pain lasts 8 to 15 days, the right side of the 2/3, atrophy often involving several muscles, and some only 1 or 2 muscles involved. There are rare signs of muscle bundle fibrillation, shoulder feel diminished, two, three tendon reflexes diminish or disappear. 67 cases of EMG 50 cases suggest brachial plexus axonal injury, see fibrillation potential and high amplitude multiphase movement unit potential,
