Purpose: This study aimed to explore the effects of additional trunk exercises on an unstable surface on the balance and walking ability of individuals with chronic stroke.
Methods: Sixteen patients with chronic stroke participated in this study. The participants were randomly assigned to two groups: experimental group (n=8) and control group (n=8). All the participants underwent a typical physical therapy program for 30 min a day. Moreover, the experimental group participated in a 30 min trunk exercise program on an unstable surface, whereas the control group participated in a 30 min trunk exercise program on a stable surface. Both groups performed the exercises five times a week for three weeks. The Berg Balance Scale (BBS) was used to measure changes in balance. The gait variables were measured using the GAITRite system (CIR System Inc., Clifton, NJ, USA) to examine changes in walking ability.
Results: Both groups showed a significant intragroup improvement in balance, gait speed, cadence, stride length, and double support period (p<0.05). In the intergroup comparisons after the intervention, the experimental group showed significant improvements over the control group in balance, gait speed, cadence, stride length, and double support period (p<0.05).
Conclusion: This study applied additional trunk exercises on an unstable surface to chronic stroke patients, and the results showed a significant improvement in the patients’ balance and walking abilities. Therefore, trunk exercise on an unstable surface may be applicable as an intervention method to improve the balance and walking ability of chronic stroke patients.
