Twenty stroke patients with chronic hemiplegia were
equally divided into 2 groups, a SET group and a control group that performed regular exercises on a mat with the
assistance of a table. Patients in both groups exercised for 30 min, three times per week for 4 weeks. Trunk muscle
activity was measured using surface electromyography, whereas balance was measured using the Berg Balance
Scale, Frailty and Injuries Cooperative Studies of Intervention Technique, Timed Up & Go test, and BioRescue
before and after the 4-week experimental period.
