Background: Knee osteoarthritis (KOA) is the most prevalent joint disease worldwide which reduces function and quality of life. It is linked to balance disorders and increased fall risk. Core strengthening may potentially improve balance, pain, and function in these patients. Methods: This pre-post intervention study involved 20 subjects who were diagnosed with KOA. Ten KOA patients (55.90 ± 7.74 years) in the control group (CG) received conventional treatment only, while 10 intervention group (IG) patients (56.40 ±8.87 years) received conventional treatment and core strengthening. Both groups performed thrice weekly home-based exercises for 6 weeks. Static and dynamic balance, functional-perfomance tests, and Knee Injury and Osteoarthritis Outcome Score (KOOS) assessing pain and function was done at baseline and after 6 weeks, with KOOS repeated after 12 weeks. Results: There was statistically significant within-group improvement in KOOS pain and function (p<0.05) after 6 and 12 weeks, however in between-group difference was insignificant. Functional tests and balance showed more improvement in the IG but was insignificant (p>0.05). No adverse events were reported with core strengthening in the IG. Conclusion Core strengthening is a safe, practical, and feasible intervention for KOA patients which may improve balance, pain, and physical function.
