Purpose

This exploratory cross-sectional study proposes, firstly, to objectify in a population of Charcot-Marie-Tooth disease type 1A (CMT 1A)if there is a correlation between the recording of electrical parameters and upper limb muscle strength of the thigh and in a second step, to seek a relationship between the measured parameters.
