The dislocation of the shoulder is a common complication of stroke, which is easy to occur after 3 months of stroke, with an incidence of 70%. There is no single standard for the pathogenesis of the disease, but the atrophy of the associated stability muscle, such as the triangle muscle, the oblique, and the upper muscle of the gonfield, may be the cause of the disease. In order to observe the effects of Electromyographic Biofeedback (EMGBF) combined with different motion directions on upper limb function with shoulder dislocation, a total of 84 patients with shoulder dislocation from May 2020 to February 2022 are selected for the study. The experimental results show that after treatment, upper limb motor function, iEMC, pain score, Barthel index, and quality of life score in the observation group are significantly higher than those in the control group, with statistical significance.
