Purpose We examined the hip joint range of motion and muscle strength in subjects with asymmetric hallux valgus angles. Study design A cross-sectional study. Methods Fifteen participants with asymmetric hallux valgus angles were recruited. Two examiners measured the hallux valgus, intermetatarsal and tibial torsion angles, and the iliotibial band flexibility. The independent t-test was used to compare the differences between the two sides. Results The side with the greater hallux valgus angle also had a larger intermetatarsal angle. The iliotibial band was significantly less flexible on this side. The tibial torsion angles did not differ significantly between the two sides. Conclusions We suggest that the hallux valgus angle is associated with iliotibial band flexibility. Therefore, stretching of the iliotibial band should be considered during rehabilitation of the hallux valgus.
