Effects of Sit-to-stand Training with Various Foot Positions Combined with Visual Feedback on Postural Alignment and Balance in Stroke Patients

PURPOSE: This study compared the effects of sit-to-stand training with various foot positions combined with visual feedback on the postural alignment and balance. METHODS: Thirty stroke patients were assigned randomly into three groups of standing with a symmetrical foot position (SSF) (n = 10), asymmetrical foot position with the affected foot at the rear (SAF) (n = 10), and visual feedback and asymmetrical foot position (SVAF) (n = 10). Sit-to-stand training with different foot positions was performed for 30 minutes a day, five times a week, for a total of four weeks, and the effects on postural alignment and balance were assessed. RESULTS: The angle between the midline and scapula peak of the affected side was decreased significantly at sitting and thigh-off in the SAF group and at sitting, thigh-off, and standing in the SVAF group (p < .05). The angle between the midline and scapula peak of the non-affected side was increased significantly at sitting and thigh-off in the SAF group and at sitting, thigh-off, and standing in the SVAF group, the difference in the angle between the scapular peaks of the left and right sides was decreased significantly at sitting and thigh-off in SSF group, and at sitting in SAF group (p < .05). In the SVAF group, the angle at sitting, thigh-off, and standing was decreased significantly (p < .05). A comparison of the balance ability showed that BSS in the SVAF group was improved significantly (p < .05). CONCLUSION: Based on these results, the postural alignment and balance ability were improved in stroke patients who participated in sit-to-stand with visual feedback and asymmetrical foot position training.
