Primary Outcome Measures:
  • CMT Peds Scale Part 1: Symptoms [ Time Frame: 1 year ]
    The CMT Peds Scale Symptoms include foot and hand symptoms.

  • CMT Peds Score Part 2: Foot and Ankle Involvement [ Time Frame: 1 year ]
    Foot 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 dexterity [ Time Frame: 1 year ]
    Hand dexterity involves hand dexterity testing and the nine-hole peg test.

  • CMT Peds Scale Part 4: Hand strength [ Time Frame: 1 year ]
    Hand strength includes grip strength, thumb-index pinch, and three point pinch.

  • CMT Peds Scale Part 5: Foot Strength [ Time Frame: 1 year ]
    Foot strength includes the strength of plantar- and dorsi-flexion, eversion, and inversion.

  • CMT Peds Score Part 6: Sensation [ Time Frame: 1 year ]
    Sensation includes pinprick and vibration sensations.

  • CMT Peds Scale Part 7: Balance [ Time Frame: 1 year ]
    Balance is assessed by the Bruininks-Oseretsky Test of Motor Proficiency, 2nd Edition (BOT-2).

  • CMT Peds Scale Part 8: Motor Function [ Time Frame: 1 year ]
    Motor function assessment includes long jump, 10 meter run/walk, stair climb, stair descend, and 6 minute walk test.

Secondary Outcome Measures:
  • Evaluate CMT Pediatric Scale (CMT Peds Scale) in CMT natural history study [ Time Frame: 6 months to 1 year ]
    The 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.

Estimated Enrollment: 500
Study Start Date: April 2010
Estimated Primary Completion Date: December 2016 (Final data collection date for primary outcome measure)
Pediatric patients
All patients 21 years of age and under who are enrolled in the 6601 study and have undergone the pediatric scale tests.

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.

Ages Eligible for Study:   up to 21 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population
Patients who are 21 years of age and under who are also enrolled in the 6601 study and have performed all tasks to complete the CMT Peds Scale will be recruited for participation. Participation entails allow the information collected in the 6601 study be used for validation in the current study.

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.
