*A χ2 test was performed to compare the three groups. The two groups were then compared using the χ2 test or Fisher’s exact test. †Group A= Copenhagen adduction exercise alone. Group B= combined intervention of Copenhagen adduction exercise and Nordic hamstrings exercise. Group C= control group. ‡The Bonferroni correction was used as a post hoc test.
