Shoulder abduction fatiguability has been measured using a hand held myometer in normal subjects and patients with peripheral neuromuscular diseases. An index of fatiguability was based on the decline in force over a series of ten maximum voluntary contractions performed in under a minute. The technique was repeatable and well tolerated. Patients with myasthenia, mitochondrial myopathy and motor neuron disease tended to show excess fatiguability independent of muscle strength. Serial measurements demonstrated alterations in fatiguability but not necessarily strength, associated with changes in symptoms.
在正常受试者和患有周围神经肌肉疾病的患者中，已使用手持肌动计测量了肩部外展疲劳性。疲劳性指数基于在一分钟内进行的一系列十次最大自主收缩过程中的力量下降。该技术具有可重复性且耐受性良好。重症肌无力、线粒体肌病和运动神经元疾病患者往往表现出与肌肉力量无关的过度疲劳性。连续测量显示，疲劳性改变但力量不一定改变，这与症状变化有关。
