Answer

Due to a loss of protective sensation distally in all 4 limbs, patients with Charcot-Marie-Tooth disease (CMT) are susceptible to skin breakdown, burns, nonhealing foot ulcers, and in severe cases, bony, bilateral foot deformities. As mentioned previously, orthoses are required for the treatment of foot drop or to accommodate bony foot deformities. If not fit properly, the orthoses themselves become a source of skin breakdown secondary to associated distal sensory impairment.

Maternal CMT increases the risk for complications during delivery; this risk is linked to a higher occurrence, in such cases, of emergency interventions during birth.
