CARPAL TUNNEL SYNDROME, CUBITAL TUNNEL SYNDROME
A large number of researchers have carried out studies related to the repair function of electrical stimulation in nerve injury, proving effectiveness and reliability from a practical point of view [Despite the potential of damaged peripheral nerves to regenerate axons, functional recovery after severe nerve injury in humans remains poor [In this study, we applied an electromyograph to intervene in the postoperative recovery of patients with cubital tunnel syndrome in the form of electrical stimulation, and two tests were applied to assess the patient's neurological recovery, i.e., electromyographic indices, and sensory and motor functions to assess the patient's clinical recovery. The electromyograph allows the adjustment of stimulation parameters and treatment time, as well as the postoperative assessment of all electrophysiological aspects of the muscle, thus providing better objectivity.In this study, sensory and motor functions were evaluated at 1 and 6 months of postoperative follow-up. The ES group showed a significantly faster motor and sensory function recovery compared to the control group. The performance of intraoperative electrical stimulation enhanced motor and sensory function recovery in cubital tunnel syndrome patients.The Lovett muscle strength grading was used to evaluate the finger muscle strength of the patients at 1 and 6 months postoperative follow-up. The comparison showed that the recovery of muscle strength in the ES group was also superior to the control group. The performance of intraoperative electrical stimulation enhanced the recovery of muscle strength after surgery.The key pinch strength and grip strength were compared between the control group and the ES group before surgery and at the postoperative follow-up of 1 and 6 months. There was no significant difference between the two groups before surgery, but the grip strength and key pinch strength recovered faster after surgery in the ES group.The CMAP and the MCV of the ulnar nerve were compared at 1 and 6 months of postoperative follow-up. The MCV and CMAP were not significantly different between the two groups before surgery, but the postoperative recovery was significantly better in the ES group than in the control group.Due to the small sample size of this experiment and the fact that only cubital tunnel syndrome after ineffective conservative treatment was selected as a therapeutic target for nerve injury, while other peripheral nerve injuries (e.g., peripheral nerve dissection due to upper limb trauma, carpal tunnel syndrome due to long-term entrapment) have not been further studied, we will next expand the sample size and further investigate the mechanism of electrical stimulation for nerve recovery.
