Electrical Impedance Myography in the Assessment of Disuse Atrophy

摘要: Abstract Tarulli AW, Duggal N, Esper GJ, Garmirian LP, Fogerson PM, Lin CH, Rutkove SB. Electrical impedance myography in the assessment of disuse atrophy. Objective To quantify atrophy using electrical (EIM), a noninvasive technique that we have used successfully to study neurogenic and myopathic Design We performed EIM tibialis anterior subjects with secondary cast immobilization their contralateral normal leg. Subjects were studied shortly after removal again several weeks months was removed mobility restored. Setting Outpatient neurology orthopedic practices at tertiary care medical center. Participants Otherwise healthy (N=10) unilateral leg fracture. Interventions Not applicable. Main Outcome Measures Resistance, reactance, phase measured 50kHz. Results The main outcome parameter, 50kHz, lower immobilized 9 10 cases. Additionally, when restored, casted increased relative its initial measurement all cases, while it inconsistently Conclusions may be powerful tool for
