Purpose The aim of this study is to investigate the effects of stair gait training after heel-raise exercise on balance, muscle tone, muscle stiffness, and manual muscle strength in stroke patients. Methods This study conducted stair gait training after heel raise exercise in a 53yearold patient with right hemiparesis due to cerebral infarction. The study was designed and conducted using an ABA design among single-subject research methods and was carried out over a total of 8 weeks. Measurements used were posture analyzer, plantar pressure analyzer, 10 meter walk test(10MWT), Time up and go(TUG), Five Times Sit To Stand(5TSTS), Berg Balance Scale(BBS), MyotonPRO and Wireless muscle tester. Results The Standing posture analysis, Plantar pressure, 10MWT, TUG, 5TSTS, BBS, Muscle tone and stiffness, MMT values showed significant changes in the intervention stage B, and this was maintained in the regression stage A'. Conclusion The stair gait training conducted after heel-raise exercises was effective in improving balance, gait ability, and muscle strength in stroke patients. It was also effective in reducing muscle tone and stiffness in the affected lower limb.
