The high-intensity interval training group showed a significant improvement in functional capacity, as measured by the Barthel Index, compared to the moderate-intensity continuous training group. The Barthel Index is a widely used tool to assess functional independence in daily living activities. A score of 100 represents complete independence, while a score of 0 indicates complete dependence. The high-intensity interval training group achieved an average improvement of 10.5 points in the Barthel Index, compared to an average improvement of 5.8 points in the moderate-intensity continuous training group.

The study also found that the intervention group experienced a significant reduction in pain levels, with a mean reduction of 40% at 12 weeks. This study investigated the effects of a novel intervention on walking distance and pain levels in individuals with osteoarthritis (OA). The intervention involved a combination of exercise and education, tailored to the specific needs of individuals with OA. The study’s design involved a randomized controlled trial (RCT) with two groups: an intervention group and a control group. The intervention group received the novel intervention, while the control group received standard care.
