About

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.

Full description

This is a prospective randomized single-blinded controlled trial with pre- and post-measurements. 20 individuals will be recruited, and randomly assigned to experimental or control group. Statistical data analysis will be done by SPSS 24.0. Baseline characteristics will be analyzed using independent t-test or Chi-square test. Repeated measures two-way analysis of variance (ANOVA) with Tukey's post-hoc analysis will be used for time-by-group comparisons. The significant level is set at 0.05.

20 participants in 2 patient groups

Visual and auditory feedback STS training group

Experimental group

Description:

The interactive interface of visual and auditory feedback system was designed using LabVIEW and integrated force plates for training. Signals from the pressure detectors of the seat and two force plates on the floor will be converted to the indication of the body weight distribution (indicated by the size of the two circles of both legs, larger circle represented the more weight beard on the leg) and the movement path of the overall center of pressure (indicated by a mobile solid dot).

Treatment:

Other: Visual and auditory feedback STS training

Conventional STS training group

Active Comparator group

Description:

Only verbal and visual cues which were commonly used by the therapist.

Treatment:

Other: Conventional STS training
