Improving Lower Extremity Functional Indices of People With Dynamic Knee Valgus With Therapeutic Exercises: A Systematic Review and Meta-analysis.

Purpose: One of the most significant contributors to lower extremity degeneration alterations and its effects on balance and sports performance is dynamic knee valgus (DKV) as a faulty movement pattern. Different exercise interventions have been conducted to improve DKV. Extensive research and meta-objective analysis were conducted to assess how exercise interventions affected people with lower extremity functional indicators of DKV. Methods: The electronic databases Scopus, Web of Science (WoS), PubMed, Google Scholar, and Iranian databases SID and Magiran were systematically searched from inception to September 2021. Only full-text articles published in English/Persian peer-reviewed journals that met this study criterion were tracked. Two researchers evaluated the methodological quality of research findings separately, employing the Downs and Black Checklist. After collecting significant data from eligible studies, the results were integrated by applying a random-effects meta-analysis approach. Results: The final systematic review and meta-analysis comprised seven of the 3470 papers deemed potentially relevant. The outcome illustrates that different exercise interventions may be effective in improving dynamic balance (SD=0.93 degrees, 95%CI: 0.54-1.32, P<0.001) and functional performance (Hedge's g=1.695, 95% CI=1.22-2.17, Z=6.99, P<0.001) in 250 DKV participants. Conclusion: Exercise interventions appear to be an effective method to enhance dynamic balance and functional performance in individuals experiencing DKV; nevertheless, these results should be regarded as preliminary due to the limited number of studies and their limitations.
