Introduction: The objective of the study was to determine the effectiveness of Otago exercise program (OEP) and strength training program (STP) on lower limb strength and risk of fall among bilateral knee osteoarthritis patients and compare its effects.
Method: Subjects diagnosed with bilateral knee osteoarthritis were included and randomly assigned into group A ( N=20) and group B ( N=20). Subjects in Group A received otago exercise program and strength training program in group B. All the subjects were assessed with baseline and post intervention outcome measure for risk of fall with The Time up and Go test (TUG) and lower limb strength with 30-sec Chair Stand Test.
Result: This study shows that the mean score Inter-group analysis of time up go test (TUG) in between Otago Exercise Program and Strength Training Program group shows (p < 0.05) with significant improvement and with mean score of 30sec Chair Stand Test (30sec CST) on the Lower limb strength in between Otago Exercise Program and Strength Training Program group shows no significant improvement with p value of 0.0570 (p>0.05).In intra group analysis the time up go test shows significant result in OEP group but not in STP group and with the 30 – sec chair stand test showed significant result in both the groups.
Conclusion: The study showed that otago exercise program is effective in reducing the risk of fall and improving lower limb strength among bilateral knee osteoarthritis than Strength training program.
