3.2. Observation indices
Before treatment and 2 months after treatment, the electromyography (EMG) of the affected side of the tibialis anterior and peroneus longus muscles was recorded using the SA7550 surface EMG analysis system produced by Nanjing Weis Medical Co., Ltd. Before and after treatment, the root mean square (RMS) value of the triceps leg passive extension,During the evaluation, the patient rested quietly for 5 minutes, the room temperature was approximately 30 to 35 °C, the lower limbs were placed in an upright sitting position, the lower legs were exposed, the skin was wiped with alcohol, the triceps electromyography electrode was connected, and the tibialis anterior and triceps muscles were fully extended. The tibialis anterior and triceps muscles are channels A and B, respectively.The muscles of channel A were actively contracted in the following steps: contract, relax, contract, relax, contract, and relax.The channel B muscles passive draft were the following: pull, relax, pull, relax, pull, and relaxThe SEMG signal was collected, and the system automatically analyzed the root-mean-square value of the surface EMG signal.
