Investigating the Immediate Effect of Feedback on the Performance of People With Abnormal Lower Extremity Movement Patterns: A Review

Abstract

Background and Aims Faulty movement patterns can lead to dysfunctional and uncoordinated mobility. A proper pattern can cause better movement. In fact, an efficient movement provides more energy for endurance and power with less effort and more mobility and agility. Many studies have reported the effect of feedback on improving faulty movement patterns as a risk factor for anterior cruciate ligament injury. This study aims to investigate whether feedback can affect the performance of people with abnormal lower extremity movement patterns or not. Methods This is a systematic review study. Related articles published from 2000 to 2020 were found by searching in international (Google Scholar, PubMed, ScienceDirect) and national (MagIran, IranDoc) databases using the keyword videotape augmented feedback, augmented feedback, feedback, jump-landing, immediate effect. Results Out of 10 reviewed studies, two were systematic review studies, one was a systematic meta-analysis study, and seven were interventional studies. In all studies, feedback methods had a positive effect on the biomechanics of the lower limb. Three studies examined the impact of feedback on performance, of which two studies stated that feedback caused a decrease in performance, while one study stated that feedback did not affect performance. Conclusion In many studies, feedback methods improved movement patterns, but further studies are needed to understand the effect of feedback on the performance of people with abnormal lower extremity movement patterns.
