Background and Purpose This study was to investigate the effects of recovery of upright standing posture on balance control in patients with stroke. Subjects and Method Two participants received treatment of physical therapy to perform realignment training for upright standing posture on 30 minutes a day, five days a week during four weeks. Patients were measured with OLST(One Leg Standing Test), TUG(Timed “Up & Go” Test) and MCTSIB(Modified Clinical Test of Sensory Interaction and Balance) by a therapist. Result The results were as following: OLST and MCTSIB were improved, but TUG was increased in two subjects. Conclusion Postural stability was improved after training of upright standing posture to recover alignment. We suggests that realignment of upright standing posture is feasible and suitable for individuals with stroke.
