  1. The “chair stand test” showed an improvement in intervention group over the course (p < .001), and between groups in favor to intervention group (p < .001). The intervention group improved in pain score (VAS, 0–10) over the course (p < .001), and was significant better between groups (p = .003) after 3 month. The overall pain response showed no significant difference between groups (p = .158). Wilcoxon U test was used between groups, signed-rank test was used within groups. Chi-square test was measured for pain response.
