Which modification is commonly required for lower limb training when foot deformities are present in CMT?

• A. Upper body exercises only
• B. Interval sprint training
• C. Weight-bearing lower limb exercises modified
• D. Increase ankle weights

Answer: (C)

When foot deformities are present in Charcot‑Marie‑Tooth, the way loads are moved through the lower limbs must be tailored to protect the feet and ankles. Foot deformities change alignment and pressure distribution, so standard weight-bearing exercises can cause pain, aggravate instability, or lead to overuse injuries. The safest and most effective approach is to modify weight-bearing lower-limb exercises. This means using partial or assisted weight-bearing as needed, supporting footwear or orthotics to improve alignment, performing controlled movements on stable surfaces, and progressing gradually with appropriate loads and repetitions. The goal is to keep the leg muscles strong, preserve function, and maintain balance while minimizing stress on the deformed feet. Upper-body-only training ignores the lower limbs and won’t address the strength and stability issues those deformities create. Interval sprinting is high-impact and risky for someone with foot deformities, potentially worsening pain or injuries. Increasing ankle weights adds extra stress to already vulnerable joints and tissues.
