Effect of somatosensory simulation training combined with EMG biofeedback on upper limb dysfunction in stroke...

To explore the effect of somatosensory simulation training combined with EMG biofeedback in the rehabilitation of upper limb function in stroke patients with hemiplegia.

Retrospective analysis of clinical data of 96 stroke patients with upper limb hemiplegia who underwent rehabilitation treatment in Xi'an International Medical Center Hospital from August 2019 to August 2021. These patients were divided into the patients into combined therapy group and control group according to the treatment modality. Patients in control group were given routine rehabilitation, and on this basis, somatosensory simulation training (SST) combined with EMG biofeedback were carried out in combined therapy group. Upper limb motor function [Fugl-Meyer assessment (FMA score), simple Test for Evaluating Hand Function (STEF score)], hand grab and relax test (HGRT), wrist active range of motion (AROM), nerve function [National Institutes of Health Stroke Scale (NIHSS score)], peripheral nerve conduction velocity, integrated EMG (iEMG) value of upper limb muscle group, and activities of daily living [modified Barthel Index (MBI score)] were compared between the two groups.

After treatment, the FMA score and STEF score of upper limb function in combined therapy group were higher, and HGTR and dorsiflexion AROM of the affected hand were also higher. Besides, NIHSS score and peripheral nerve conduction velocity of patients in combined therapy group were better improved, and iEMG values of upper limb muscle groups were higher, which effectively improved patients' activities of daily living and BMI score.

SST combined with EMG biofeedback can better help stroke patients control the movement and muscle contraction of hemiplegic upper limbs, and improve the conduction velocity of peripheral nerve, so as to better improve patients' activities of daily living.
