While performing sit-ups, a 70-year-old man was unable to lift his upper body. The abdominal skin reflex was absent, and abdominal ultrasonography showed intermittent, irregular, and localized muscle twitches of the abdominal muscles. Further, electromyography (EMG) detected widespread fasciculations. Amyotrophic lateral sclerosis (ALS) was diagnosed. Muscle ultrasonography (MU) is useful in detecting fasciculations. This technique allows for repeated non-invasive imaging and the assessment of an expansive range of muscles in real-time. It also detects deep abdominal muscles, which are difficult to assess using EMG. MU is particularly beneficial to patients with atypical ALS who experience truncal muscle weakness.
在做仰卧起坐时，一名70岁男性无法抬起上半身。腹壁皮肤反射消失，腹部超声显示腹部肌肉有间歇性、不规则和局限性肌肉抽搐。此外，肌电图（EMG）检测到广泛的肌束震颤。诊断为肌萎缩侧索硬化症（ALS）。肌肉超声（MU）有助于检测肌束震颤。该技术允许进行重复的非侵入性成像，并实时评估大范围的肌肉。它还能检测到深部腹部肌肉，而这些肌肉使用肌电图很难评估。MU对患有非典型ALS且出现躯干肌无力的患者特别有益。
