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.

Detailed Description:

Patients suffering from CMT 1A neuropathy will be invited to go through a series of tests such as:

  • Electromyography
  • Isokinetic test
  • Podiatric assessment
  • Functional evaluations: Hand dexterity, limbs muscles strength
  • Quality of life assessment with questionnaires

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Probability Sample
Study Population
