Gait and balance improvements with a carbon fiber ankle-foot orthosis in a patient with Charcot–Marie–Tooth disease: A case report

Charcot–Marie–Tooth (CMT) disease is a common inherited peripheral neuropathy characterized by progressive distal muscle weakness, sensory deficits, and gait abnormalities. This case report describes a 42-year-old male university faculty member diagnosed with CMT disease at the age of 15 years, who now experiences progressive gait instability, distal muscle weakness, and frequent falls. Comprehensive physical therapy evaluation revealed significant foot drop, impaired dynamic balance, and increased fatigue during ambulation. A targeted rehabilitation program was implemented, incorporating the use of carbon fiber ankle-foot orthoses and gait training. The intervention led to measurable improvements in gait mechanics, postural control, and energy efficiency. This case reinforces the importance of individualized rehabilitation strategies and assistive devices in managing functional decline associated with chronic and progressive neuromuscular conditions such as CMT.
