Purpose: The aim of this study was to investigate the effects of sit-to-stand training with various foot positions combinedwith visual feedback on muscle onset time and balance in stroke patients.
Methods: Thirty stroke patients were randomly assigned into three standing groups: one with a symmetrical foot position(SSF; n = 10), one with an asymmetrical foot position with the affected foot at the rear (SAF; n = 10), and one withvisual feedback and an asymmetrical foot position (SVAF; n = 10). Sit-to-stand training with different foot positionswas performed for 30 minutes a day, 5 times a week, for a total of 4 weeks. The effects on muscle onset time andbalance were assessed.
Results: In a comparison of the onset time of muscle contraction, the onset time of the affected side tibialis anteriorand less-affected side gastrocnemius muscle and tibialis anterior was significantly shortened in the SAVF group. Andonset time of the less-affected side tibialis anterior was shortened in the SAF group. There was a significant differencein the result of functional reach testing in the SVAF group.
Conclusion: VRG was effective in improving muscle activity and balance in elderly women aged 65 and older. In thisstudy, sit-to-stand training with visual feedback and asymmetrical foot position showed significant functional improvement.
