Evaluation on Muscle Tone Disorder Degree Based on Bioimpedance Spectroscopy
摘要
Abstract
This paper proposes a method for identifying muscle tone disorders based on bioimpedance spectroscopy,which addresses the challenge of classifying muscle tone in clinical practice.With the focus on the biceps brachii,triceps brachii and gastrocnemius muscles,the bioimpedance spectra of these muscle groups were measured using the IM3570 impedance analyzer,disclosing that the relaxation impedance of muscle tone-affected areas was significantly lower than that of normal areas.In the case of patient 1,the relaxation impedance of the muscle tone-affected area was 30-50,while the impedance of the normal area was 50-100.An equivalent circuit model was constructed,which corresponds to the different biological tissues of the target areas.The measured impedance spectra were input into the equivalent circuit model to extract key electrical characteristic parameters:intracellular resistance(Ri),extracellular resistance(Re),and cell membrane capacitance(Cm).Using these extracted parameters,muscle tone presence or absence was classified with an accuracy rate of up to 94.7％.The proposed method holds promise for the classification and assessment of muscle tone levels.关键词
