Knee stability training exercise versus Biodex balance training on dynamic balance indices in individuals with knee osteoarthritis: A Randomized clinical trial

Abstract

Objective. To compare the impacts of Knee stability training exercise versus Biodex balance training on dynamic balance indices in individuals suffering from knee osteoarthritis. Methods. This randomized, double-blind, pre-post measurement study included forty patients aged 45 to 65 with knee osteoarthritis. They were classified into 2 groups at random: group A (n = 20), which received knee stability training plus strengthening exercise, and group B (n = 20), which received Biodex balance training plus strengthening exercise. The Biodex Balance System and Visual Analog Scale were utilized to quantify dynamic balance indices as well as pain intensity at baseline and four weeks following therapy. Results. Statistically significant differences were reported in the overall stability index (OASI), anterior-posterior stability index (APSI), medial-lateral stability indices (MLSI), and Visual Analogue Scale (VAS) values before and after treatment for group A (p < 0.05) as well as before and after treatment for group B (p < 0.05). Statistically significant differences were reported among the two groups (A & B) regarding the post-treatment values of the OASI, APSI, MLSI, and VAS (p < 0.05). Conclusion. Improvement in all dynamic balance indices and pain was reported after knee stability training exercises and after Biodex balance training, with greater improvement after Biodex balance training.
