Charcot Marie Tooth Disease

Brief summary

The primary goal of this project is to develop and test a Charcot Marie Tooth disease (CMT) Pediatric Scale for use in evaluation in natural history CMT study.

Detailed description

This project is to develop a new CMT Pediatric Scale (CMTPeds) for Children with CMT. Although there is a validated score (the CMTNS) which measures disease severity for CMT, it is not always applicable to children due to their limited ability to relay information about their symptoms. The CMTPeds scale is being developed and validated in order to measure disease severity in children and have outcome measures available for future clinical trials. Children (defined as 21 and under) being evaluated will be asked to perform functional tasks such as using stairs, walking in a hallway, and performing hand function tests. This information will be used to validate the CMTPeds score. It is important to have validated instruments to measure disease severity in childhood so these can be used with clinical treatment trials are available.

Inclusion criteria

All patients MUST be seen in person at one of the participating centers for enrollment in this study. * Children (\< 21 years of age) * Known or probable inherited neuropathies classified as CMT1, CMT2, or CMT4

Exclusion criteria

* Known diagnoses of acquired neuropathy including toxic (e. g. medication related neuropathies); metabolic (e.g. diabetic), immune mediated or inflammatory \[acute inflammatory demyelinating polyradiculoneuropathy (AIDP) or chronic inflammatory demyelinating polyneuropathy (CIDP)\] polyneuropathies; neuropathy related to leukodystrophy, congenital muscular dystrophy; and patients with severe general medical conditions. * Entirely normal conduction velocities of upper and lower limbs as this suggests that the subject may not have a neuropathy.

Design outcomes

Primary

MeasureTime frameDescription
CMT Peds Scale Part 8: Motor Function1 yearMotor function assessment includes long jump, 10 meter run/walk, stair climb, stair descend, and 6 minute walk test.
CMT Peds Scale Part 1: Symptoms1 yearThe CMT Peds Scale Symptoms include foot and hand symptoms.
CMT Peds Score Part 2: Foot and Ankle Involvement1 yearFoot and ankle involvement includes foot posture index, range of ankle dorsiflexion, foot drop present/absent, and whether or not difficulty heel/toe walking.
CMT Peds Scale Part 3: Hand dexterity1 yearHand dexterity involves hand dexterity testing and the nine-hole peg test.
CMT Peds Scale Part 4: Hand strength1 yearHand strength includes grip strength, thumb-index pinch, and three point pinch.
CMT Peds Scale Part 5: Foot Strength1 yearFoot strength includes the strength of plantar- and dorsi-flexion, eversion, and inversion.
CMT Peds Score Part 6: Sensation1 yearSensation includes pinprick and vibration sensations.
CMT Peds Scale Part 7: Balance1 yearBalance is assessed by the Bruininks-Oseretsky Test of Motor Proficiency, 2nd Edition (BOT-2).

Secondary

MeasureTime frameDescription
Evaluate CMT Pediatric Scale (CMT Peds Scale) in CMT natural history study6 months to 1 yearThe sections of the CMT Peds Scale which are found to be clinically/functionally useful after one year of analysis will be carried forward for all pediatric patients every 6 months to one year.
