Effects of Isometric Training of Scapular Muscles on Trunk Muscle Activation and Trunk Control in Patients with Stroke

Abstract

Purpose This study was to identify the effects of isometric training of the scapular muscles on trunk muscle activity and trunk control in patients with stroke. Methods A total of 25 subjects with stroke were recruited. Subjects were assigned as block randomization to either the study group (n = 13), or the control group (n = 12). Electromyography (EMG) measured muscle activation of trunk flexor and extensors, and trunk control was measured with a Trunk Impairment Scale (TIS). Results Isometric training was significantly improved in the symmetricity of erector spinae thoracic (p<0.05). Trunk control was significantly increased in TIS score (p<0.05). Conclusion Isometric training of the scapular muscle can improve trunk muscle activity symmetry and trunk muscle control in patients with stroke.
