The validation of an innovative hallux valgus sock for hallux valgus deformities

Abstract

Introduction: The purpose of the present study is to test the hypothesis that an innovative Hallux Valgus [HAV] sock reduces HAV angle and restores a more normal foot function in persons living with Hallux Valgus. Methodology: A prospective, same-subject, pre-post experimental study was conducted on twelve participants presenting with HAV. Laboratory tests utilizing electromyography in order to investigate foot function during gait with and without wearing the HV sock, lab tests utilizing foot pressure mapping in order to investigate plantar pressure distribution during gait with and without wearing the HV sock and laboratory photographic measurement of hallux valgus angle were taken. Results: The innovative hallux valgus sock reduced the peak plantar pressure on most anatomical landmarks, including the first toe/hallux, first metatarsal head, second to fourth metatarsal head, however, no significant difference in pressure was noted on the fifth metatarsal head in both right and left foot. Hallux valgus angle reduction was evident in both left and right angle for all subjects. Finally, EMG results show that 50% of the patients showed an increase in the muscle function during walking. Conclusion: The innovative hallux valgus sock reduced the peak plantar pressure on most anatomical landmarks, it reduced the hallux valgus angle and muscle function during walking was also increased. Apart from being user-friendly and low-cost, this sock is especially designed to be easy to use and unobtrusive to ensure patients daily compliance. The HAV sock is innovative in nature, since no other sock with such properties exist to date. This offers a novel alternative to clinicians and patients in the management of HAV.
