EFFECTIVENESS OF A NEW BALANCE TRAINING PROGRAM ON ROCKER BOARD IN SITTING IN STROKE SUBJECTS A PILOT STUDY

Abstract

Background: Stroke has been considered to be the most common cause of neurological disability with very high prevalence rate. The recovery of independence following stroke is a complex process requiring the reacquisition of many skills. Since controlling the body’s position in space is essential part of functional skills, restoration of balance is a critical part of the recovery of ability after stroke. Most of the work done regarding balance training in stroke subjects has focused on task-oriented activities and training under varied sensory input and found them to be effective. Studies have also compared the effect of stable and unstable surfaces on balance in stroke subjects and found that balance training on unstable surfaces is more effective in improving static and dynamic balance. There has not been any study till date investigating the effectiveness of balance training program on rocker board which is specific for stroke subjects who have difficulty in standing. Since balance training on rocker board in sitting has proved to be effective in improving balance in subjects with spinal cord injury who have difficulty in standing, there is a need to find out if similar balance training program on rocker board in sitting is also effective for improving balance of stroke subjects.
Method: A Pilot study was performed on 10 stroke subjects selected through purposive sampling. Subjects were divided into two groups by randomization as control (CG) and experimental group (EG). EG received balance training on a rocker board along with conventional physiotherapy program. The CG received only conventional physiotherapy program.
Results: Post-intervention Berg balance scale score of EG and the CG was statistically significant (p < 0.05) in both the groups as compared to pre-treatment depicted through Wilcoxon signed rank analysis within the groups. Greater improvement was observed in the EG compared to the CG post-treatment, analysed through Mann-Whitney U test with statistically significant results (p < 0.05).
Conclusion: The new balance training program on rocker board in sitting is effective for improving balance of stroke subjects.
