Electrical impedance myography (EIM) is a new technique with potential for the noninvasive bedside assessment of myopathy. EIM was performed on the quadriceps of 10 patients with inflammatory myopathy and 10 normal subjects. The major EIM parameter, the spatially averaged phase, was 35% lower in the myositis patients and correlated with whole-body (r = 0.765, p = 0.01) and quadriceps (r = 0.673, p = 0.03) strength.
电阻抗肌电图（EIM）是一种具有对肌病进行无创床边评估潜力的新技术。对10例炎性肌病患者的股四头肌和10名正常受试者进行了电阻抗肌电图检查。主要的电阻抗肌电图参数，即空间平均相位，在肌炎患者中降低了35%，并且与全身肌力（r = 0.765，p = 0.01）和股四头肌肌力（r = 0.673，p = 0.03）相关。
