Pilot Study to Evaluate Fatigue and Fatigability Profiles and Their Impact on Walking and Balance in Patients With Charcot-Marie-Tooth Type 1A Disease Using a Global Approach in Comparison to Healthy Volunteers

Starting soon · Not applicable

Conditions studied: Charcot-Marie-Tooth Type 1A

In brief

Charcot-Marie-Tooth disease type 1A is the most common form of inherited neuropathy that causes peripheral nerve damage in all four limbs. In addition to the well-known distal motor and sensory symptoms, fatigue is one of the most common symptoms reported by patients. However, there is very little scientific data on this topic. Fatigue is associated with changes in mobility and quality of life. This study investigates the magnitude and impact of fatigue on patients' sensory-motor function and mobility (standing and walking). Fatigue is a complex phenomenon. It is therefore essential to assess all the factors that may be at the origin of this symptom (perceived fatigue and fatigability) using innovative and robust assessment methods. These methods are based on quantitative non-invasive neurophysiologic measures (electromyography and transcranial magnetic stimulation). The patients can quantify and identify more precisely the origin of fatigability (peripheral and central). This objective approach needs to be combined with the usual methods of measuring fatigue using valid and reliable patient-reported outcome measures. A quantitative measure of movement during walking must also be included to assess changes in fatigue during functional movement. To quantify the proportion of fatigue associated with CMT1A, the investigators chose to compare data from patients with those of healthy subjects matched for age, height and lean body mass. A better understanding of the role of fatigue in limiting walking and balance capacities in these patients will allow the investigators to refine the inpatient and outpatient management.
