Sit-to-stand Training With Interactive Feedback in Chronic Stroke

Summary

The major problems of people with chronic stroke include muscle weakness, sensory alteration, and inter-muscular coordination impairment. Inter-muscular coordination impairment caused altered muscle contraction sequences and weight-bearing asymmetry during functional activities. Sit-to-stand (STS) training is often used to improve functional activities among post-stroke subjects. However, the improvement may come from compensatory movements. Using compensatory movement may cause muscle weakness in the affected side and increase fall risk. This study will develop a novel STS training system with interactive visual and audio feedback emphasizing weight transferring and weight bearing. The present study aims to investigate the effects of sit-to-stand training with interactive visual and audio feedback on muscle contraction sequences and weight bearing symmetry in individuals with chronic stroke.

Conditions

Interventions

OTHER

Visual and auditory feedback STS training

30 minutes per session, 3 sessions per week, for a total of 3 weeks. The visual and auditory feedback signals will be given throughout the sit-to-stand movement. As the size of circle representing the weight bearing gets more even, and the mobile dot indicating the overall center of pressure moves forward and approaches the midline, the auditory cues will get louder to indicate proximity to the target. It allows the participants to adjust and relearn the correct weight shifting and symmetry. The intensity will be adjusted based on different chair heights (e.g. 115%, 100%, 80% of lower leg length), various seat materials, and supported level of thigh (progressing from one-third of the length between the greater trochanter of the femur and the knee joint line to full support). The training program will be progressed according to the abilities of the participants.

OTHER

Conventional STS training

30 minutes per session, 3 sessions per week, for a total of 3 weeks. All settings will be the same as the experimental group, except for the feedback. In the control group, the verbal cues will be given by the physical therapist and a mirror will be placed in front of the participant for visual feedback. During the sit-to-stand movement, participants will be asked to try to maintain the alignment in the midline.
