## 5 Conclusions  
In conclusion, the intervention combining AVGs with CPT resulted in significant improvements in perceived functional disability among individuals with knee and hip OA. The EG demonstrated consistent improvements in pain, stiffness, and function, outperforming the CG, which received CPT alone, particularly at post-test 3. The GRoC analysis indicated a moderate favorable change in the EG, while the CG exhibited more limited progress. Regarding the MCID, the EG showed a higher frequency of pain reductions, particularly in the Rs category, with statistically significant differences compared to the CG. These findings highlight the effectiveness of the combined intervention, as a larger proportion of participants in the EG exhibited positive changes in WOMAC scores. Quartile analysis further revealed that the EG made greater strides toward higher quartiles in WOMAC scores, reflecting clinical improvement, whereas the CG showed less progress. Overall, these results suggest that AVGs may enhance the benefits of traditional exercise and represent a promising approach for optimizing rehabilitation in knee and hip OA, with high adherence and no adverse events. Future research should investigate the long-term effects of AVGs and explore their potential in other therapeutic modalities and contexts, using larger sample sizes and extended follow-up to assess the sustainability of these outcomes.
