knee valgus is more common in females than in males. Normal Q-angle in girls is about 13.8±2.9 degrees. Excessive knee called genu-valgum abnormality, causing knee pain and PFP syndrome and so on. Numerous training methods had been shown efficacy in correcting this abnormality but there is not study that comparing these methods. So, the main aim of this study was to compare the Kendall and Sahrman training approach in girls with genu-valgum.
In this quasi-experimental study, 41student with Q-angle more than 15 degrees were randomly divided into three groups of Kendall corrective exercises group (n=15) with mean Q-angle 18±0.77 Sahrman corrective exercises (n=14) with mean Q-angle 17±0.84 control group (n=12). Mean Q-angle 18±0.71. then-experimental groups took part in protocol exercises with the same intensity based on Kendall and Sahrmann theory on genu-valgum, for 8 weeks, 3 sessions per week and each session for 45 minutes. The Q-angle was assessed by goniometer in the right leg and in lying position before and after 8 weeks of training. Covariance analysis, t-test was used for the inferential analysis of data. (α≤0.05).
findings showed that Kendall and Sahrman's corrective exercises were affected by Q-angle. Significant differences were also observed between the two groups (p≤0.05) so that the mean scores of the Kendall exercise group were lower in Q-angle than the other two groups. Sahrmann's corrective exercises group also display significant changes in post-test than pre-test, but the mean difference of this group was lower than Kendall corrective exercises.
Therefore, it can be concluded that performing these exercises can be effective in improving the Q-angle of people with knee valgus abnormality. Also seems that Kendall corrective exercises are more effective.
