Fasciculations are an important neurological sign of spinal muscular atrophies. 26 patients able to walk suffering from adult onset spinal muscular atrophies were examined by real time sonography. On an average 18 limb and extremity muscles on both sides were examined. In 21 cases fasciculations became sonographically apparent as muscular twitchings lasting for 0.2 to 0.5 seconds. Detection of fasciculations in profound muscular layers and in obese patients was easier by sonography than by clinical examination.
肌束震颤是脊髓性肌萎缩的重要神经学体征。对26例能够行走的成年起病脊髓性肌萎缩患者进行了实时超声检查。平均双侧检查了18块肢体肌肉。在21例患者中，肌束震颤在超声下表现为持续0.2至0.5秒的肌肉抽搐。与临床检查相比，超声检查更容易在深层肌肉和肥胖患者中检测到肌束震颤。
