This study aims to determine the difference in effectiveness between the square stepping exercise and the Otago exercise on increasing muscle strength, stride length, and dynamic balance in patients with knee osteoarthritis. This research is a quasi-experimental study with a pretest-posttest design with 2 paired groups. A total of 36 people suffering from knee osteoarthritis were divided into two groups, each consisting of 18 people. The first treatment group was given a square stepping exercise and the second treatment group was given an Otago exercise. Paired t-test was used to determine changes before and after giving training and an independent t-test to determine comparisons between treatment groups. Before being given treatment in the first week, pretest leg muscle strength using the 30-second chair stand test (30 SCT), stride length using meterline and balance measurement using time up and go (TUG). then in the eighth week, a posttest was carried out after 15 treatments. There was an increase in muscle strength, stride length, and dynamic balance in the treatment group that was given the square stepping exercise and the treatment group that was given the Otago exercise (p=0.000). Furthermore, the independent t-test found that the square stepping exercise has a higher difference in increasing muscle strength and decreasing dynamic balance than the Otago exercise (p = 0.492 and p = 0.000), but with increasing stride length, a higher difference in step length addition is obtained. on Otago exercise than square stepping exercise (p=0.263). This study shows that 5 weeks of square stepping exercise is more effective in increasing dynamic balance compared to Otago exercise.
