摘　　要：目的 通过测量局部肌肉的阻抗和相位信息,建立一种评价局部肌肉拉伤及康复情况的新方法.方法 采用局部阻抗测量方法提取拉伤肌肉的阻抗和相位值,以左右对称部位为伤前参考值,对拉伤肌肉组织的伤情及随后的恢复情况进行监测与评价.结果 拉伤肌肉组织的阻抗值明显下降.在康复过程中,其阻抗和相位值随时间逐步上升,并在康复后期达到或接近于健康侧肌肉的参考值.结论 局部阻抗测量有望为拉伤肌肉组织的伤情判断和恢复监测提供一种新的,无创、简便的评价方法,显示了良好的临床应用前景.Objective To establish a new methodology of evaluating rehabilitation status of local muscle injured by measuring the impedance and phase information.Methods An evaluation method was set up,which take symmetrical parts of injured muscle as control group during the measurement.Impedance and phase values of injured muscle were extracted with local impedance measurement method before and after rehabilitation to evaluate muscle recovery.Results Injured muscle tissue impedance values decreased significantly.In the process of rehabilitation of injured muscle,the impedance and phase values of the injured muscles were gradually approaching that of healthy muscle,and then achieved basically the same as reference values after rehabilitation.Conclusions Local impedance measurement method may provide a new,non-invasive and convenient evaluation method for the recovery of injured muscle tissue,and it has good prospects for clinical application.
