Summary

The primary aim of this study is to discover whether patients with CMT type 1 and 2 have neuromuscular junction transmission deficits. The secondary aim is to collect information of different clinical and electrophysiological test procedures to perform possible future clinical trials in CMT patients.

Detailed description

The study is a prospective observational pilot study involving two investigational sites: 1. Department of Neurology, Arhus University Hospital 2. Department of Neurology, Ohio State University A total of 20 patients with Charcot-Marie-Tooth (CMT) disease and 10 healthy age-matched controls will be included with each site including 10 CMT patients and 5 Healthy Controls. CMT patients will undergo electrophysiological (repetitive nerve stimulation and single fiber EMG analyses) and functional (different tests of muscle strength, fatigability, dexterity, and balance) testing on 4 separate occasions. Healthy controls will undergo electrophysiological testing at baseline only. To assess whether patients with CMT have deficits in NMJ transmission, results from repetitive nerve stimulation and single fiber EMG analyses in CMT patients will be compared to those obtained in healthy controls at baseline. To inform future clinical trials, results relability and tolerability estimates obtained from sequential electrophysiological and functional tests will be calculated
