Summary

This study looks at how well ankle-foot orthoses (AFOs) and surgical correction help people with Charcot-Marie-Tooth disease (CMT) and cavovarus foot deformity walk and keep their balance. Researchers will test 66 participants on stepping, walking speed, and balance confidence. The goal is to understand the pros and cons of each approach, not to find a cure.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Ankle-foot orthosis (AFO) device
What this could lead to
If successful, this study could help doctors and patients choose between AFOs and surgery for better walking and balance in CMT.
What could go wrong
This is an early observational study with only 66 participants, so results may not apply to everyone with CMT. It does not test a new treatment or cure.

This is an AI summary of the original study and may miss details. Read our disclaimer.

Inclusion Criteria: 1) Clinical diagnosis and genetic confirmation of CMT, 2) Between the ages of 12 and 75, 3) Able to walk at a slow to moderate pace without an AFO, 3) Able to read and write in English and provide written informed consent. 4) Individuals in the NonOP group must have an AFO prescribed for daily activities. Individuals in the OP group will also have had 5) surgical correction of CMT cavovarus foot deformity focused on muscle balancing and hindfoot correction. Exclusion Criteria: 1) Other causes or risk factors for peripheral neuropathy (for example diabetes, ETOH abuse), 2) Uncorrected visual impairment, 3) History of musculoskeletal injury requiring surgery 4) loss of plantar protective sensation 5) Pain \>4/10 while walking (or an increase in pain during testing of \>2/10), 6) Concern by the examiner that the individual will not complete the study.
