Objectives The aim of this study was to evaluate the effects of a corrective exercise protocol on the frequency spectrum of Ground Reaction Force (GRF) in older adults with genu valgum during double-leg drop-landing task. Methods & Materials The is a quasi-experimental study (a registered clinical trial with code: IRCT2016110230657N1). Participants were 26 elderly men with genu valgum (13 in intervention group and 13 in control group). The GRF data were measured by two force plates (Kistler Group, Winterthur, Switzerland). The corrective exercise was performed for 16 weeks, 3 sessions per week. All participants signed a written consent form and the study design was approved by the ethics committee. Those subjects with a history of injury were excluded from the study. The two-way repeated measures ANOVA was used for statistical analysis. Results The mean age of participants in the intervention and control groups were 63.92±2.21 and 64.01±2.62 years, respectively. Based on the ANOVA results, the effect of time factor on the frequency with a power of 99.5% in vertical GRF (P=0.003) and the number of essential harmonics in anterior-posterior direction (P=0.006) was significant in the left leg. The effect of group factor on the 99.5% frequency power (P=0.006) and the number of essential harmonics of vertical GRF (P=0.047) in the left leg was also significant. Furthermore, the interaction effect of group and time on the 99.5% frequency power (P |
