Foot measures in patients with pes cavus with and without charcot–marie–tooth disease: A pilot study

INTRODUCTION: Pes cavus often signals the presence of Charcot-Marie-Tooth (CMT) in adult patients, although its prevalence in the general population makes it a finding of unclear significance. METHODS: We undertook a pilot double cohort study to investigate the feasibility of comparing preselected bedside and radiographic foot measures in pes cavus patients with and without CMT. RESULTS: A total of 16 CMT and 11 non-CMT patients were recruited. Although no findings consistently met statistical significance, recruitment was highly limiting. CONCLUSIONS: Formalized foot measurement comparisons of CMT and non-CMT pes cavus are feasible. Larger studies will be necessary to determine if there are differences in foot structure based on the presence of a hereditary neuropathy. Muscle Nerve 59:122-125, 2019.
