The objective is to study the effect of hip abductors and lateral rotators strengthening exercises on improving the knee valgus alignment among adolescents.
In accordance to the well known fact that knee dysfunction condition among growing adolescents contributes to a wider segment of entire orthopedic practice, it is therefore essential to aware of the effect of strengthening the hip muscles on correcting functional knee valgus problem. So, we conducted this study to find out the effect of strengthening hip abductors and lateral rotators exercises on functional knee valgus among healthy adolescents.
30 subjects (25 females and 5 males) aged between 18 to 20 years old.
The subjects were assigned to hip abductor and lateral rotator strengthening exercises 3 times per week for 6 weeks. Knee valgus alignment was assessed at baseline and post-intervention.
Paired t-test and Microsoft Excel 2010 were used for data analysis. The mean difference for the pretest group is 161.071±5.106 while the posttest group is 166.867±5.106. There is a difference in variance between pre and post intervention with a difference of 5.6977. Paired sample test value shows a t value of -29.446119 and a p value of p<0.00001. The result is significant at p ? 0.01.
The hip abductors and lateral rotators strengthening exercises are effective in reducing the dynamic knee valgus alignment among the adolescents.
