Abstract
| Background: Knee osteoarthritis (KOA) ranks among the most common chronic joint diseases globally. By enhancing local blood flow and tissue metabolism, CSWD aids in eliminating inflammatory agents and metabolic waste while improving the delivery of oxygen and nutrients to the affected areas. The study aims to compare the efficiency of interferential current therapy and shortwave diathermy along with exercise in improving functional activity and decreasing the pain in patients who have knee osteoarthritis grades 2 and 3. Methods: A total of 20 patients were recruited and assigned randomly into two groups (A and B) by doing a randomized controlled trial. Group A received Interferential therapy while Group B received Shortwave Diathermy in a continuous mode; both groups were given the same home exercise program for knee osteoarthritis. The Intervention duration was for 2 weeks with 5 consecutive days per week for both groups, resulting in 10 sessions of treatment per patient. Pain (VAS) and function (WOMAC) were evaluated on the first and last day of the therapy. T-tests for paired and independent samples were used for statistical analysis. Results: Paired t-test showed improvement in pain VAS and function ability WOMAC in both the groups; however, the changes are not statistically significant (p>0.05). Between group comparison using an independent t-test revealed that group A demonstrated greater mean improvement in WOMAC (9.70±5.01) and VAS (3.30 ± 1.34) scores compared to group B (WOMAC: 8.30 ± 5.54; VAS: 2.60 ± 1.51). However, the difference between groups was not statistically significant (WOMAC: p = 0.561; VAS: p = 0.286). Conclusion: Both interferential therapy and shortwave diathermy showed improvement in functional ability in patients with knee osteoarthritis. However, interferential therapy demonstrated a relatively greater reduction in pain also, although the difference was not statistically significant.
