This study evaluated a group of 200 pediatric patients (ages 3- 20 years) with genetically classified types of Charcot-Marie-Tooth (CMT) disease assessed serially over a 2-year period using the CMT Pediatric Scale (CMT PedS). This is a validated Rasch-built disability scale which evaluates gross and fine motor function, strength, sensation, and balance. The 4 most common genetic types were 58% CMT1A, 5% CMT1B, 4% CMT2A, and 4% CMT4C. The study provides information about the rate of natural progression of deficits in the CMT subtypes.
Comment: The following conclusions were reached in this study:
1. CMT PedS is sensitive to progress of CMT.
2. The rate of progress differed between most common subtypes of CMT.
3. Children with CMT deteriorate significantly over a 2-year period.
