Charcot-Marie-Tooth (CMT) disease is a common inherited nerve disorder that affects walking and balance, significantly lowering quality of life. This research aims to better understand how ankle-foot orthoses (AFOs), a common supportive device, compare to surgical correction in improving mobility and balance for people with CMT and cavovarus foot deformity. Currently, there is limited scientific evidence to guide decisions between using AFOs or surgery, and expert opinions often conflict. Participants will be divided into two groups: those who have undergone surgical correction (OP group) and those who use AFOs without surgery (NonOP group). The study involves mobility and balance tests conducted in a gait analysis lab to evaluate how these treatments affect walking patterns, balance confidence, and fall risk. AFOs are meant to reduce falls and normalize gait but can be bulky or uncomfortable, whereas surgery aims to improve foot alignment and ease of use but carries risks and requires recovery. During the study, participants will undergo various assessments at the start, including balance tests, walking speed measurements, balance confidence questionnaires, fall frequency surveys, and detailed gait analysis. Researchers will monitor these outcomes to compare the effects of AFO use with surgical correction on mobility and balance. The study helps identify treatment benefits and limitations to better support people with CMT in managing their walking and balance challenges.
