To study the clinical effect of sensory amplification on the improvement of nerve function and limb motor function in young and middle-aged patients with hemiplegia after cerebral infarction.

Forty young and middle-aged patients with post-cerebral infarction hemiplegia were selected as the research objects and randomly divided into experimental group and control group, with 20 cases in each group. Experimental training by sensory augmentation method, the control group using the random vibration method training, then compared between two groups of intervention security, nerve and body movement function index [afraid of fall, functional gait assessment score changes, activities, special balance confidence score changes, ground free gait speed, Fugl-Meyer assessment (FMA) score, National Institute of Health stroke scale (NIHSS) score, etc.], as well as the clinical prognostic indicators (Barthel index).

There were no significant differences in onset time, hemiplegia position, gait score, active-specific balance confidence score, FMA score and NIHSS score between 2 groups before training (P>0.05). There was no significant difference in the incidence of adverse events between the two groups in terms of training safety (P>0.05). After the training, the gait score, activity specific balance confidence score, FMA score and NIHSS score of the experimental group were better than those of the control group, and the difference was statistically significant (P<0.05). The long-term clinical prognosis of patients in the experimental group was better than that in the control group, and the difference was statistically significant (P<0.05).

Sensory amplification training has good safety and can improve the nerve and motor function of young and middle-aged patients with post-cerebral infarction hemiplegia.
