Validation of the foot function index in people with Charcot-Marie-Tooth disease type 1A


  • Foot Function Index (FFI) is a promising scale for assessing foot-related disability in people with Charcot-Marie-Tooth type 1A (CMT1A) disease.

Why this matters

  • Charcot-Marie-Tooth (CMT) disease is the most frequently occurring inherited peripheral neuropathy, of which CMT1A is the most common form.

  • The FFI has been previously validated in orthopedic and rheumatologic disease, and in the absence of currently validated questionnaires in neurologic diseases, it could be a promising tool to assess foot-related disability in CMT.
