Pediatrics & CMT
If your child has just been diagnosed, take a breath. Most children with CMT grow up to live full, active lives, and a strong community is ready to help. CMT is, for many families, a childhood condition: symptoms often begin in the early years, even when a formal diagnosis comes later. HNF advocates for early intervention because the steps a family takes in childhood, the right therapy, the right bracing, and the right school support, can protect function and quality of life for years to come. You are in the right place.
Early signs in children
CMT looks different in every child, and many of these signs are easy to mistake for ordinary clumsiness. A pattern that persists, especially with a family history of CMT, is worth raising with a pediatrician or neuromuscular specialist.
Supporting your child
Care for a child with CMT is multidisciplinary. No single specialist does it all; the value comes from a coordinated plan across medicine, therapy, and school.
- 1 A clinical team that knows CMT A pediatric neuromuscular specialist can diagnose CMT, confirm the subtype, and coordinate care. Genetic confirmation also flags medications to avoid and any subtype-specific concerns.
- 2 Physical and occupational therapy PT builds and protects strength, flexibility, and balance; OT supports handwriting, daily tasks, and independence. Gentle, regular movement is part of care, not a risk.
- 3 Bracing and orthotics Ankle-foot orthoses (AFOs) and well-fitted footwear improve stability, reduce falls, and can ease fatigue. Growing children need periodic refitting.
- 4 School support A 504 plan or IEP can secure accommodations: extra time, mobility help, PE adjustments, seating, and rest. Documentation from the care team makes the case.

Parents often worry that activity will speed up CMT. The opposite is usually true: appropriate, low-impact movement helps maintain strength, flexibility, and confidence. A physical therapist who knows CMT can tailor a program that builds ability without overworking already-vulnerable muscles.
Bracing is not a sign that things are getting worse. A well-fitted AFO simply does the work a weakened muscle cannot, so a child can keep up, fall less, and tire less. Because children grow, plan on regular refitting.
Just as important is the team around a child. A pediatric neurologist, a physical therapist, an orthotist, and the school can all work from the same plan, so a child is supported at home, in the clinic, and on the playground. Children are remarkably adaptable, and the goal is never to hold them back. It is to keep them moving, included, and doing the things they love, for as long and as fully as possible.
“CMT-specific registries provide the baseline data needed to accelerate care. Their longitudinal, real-world data speeds up research and clinical trial readiness, supports evidence-based care standards, and helps ensure children & adults with rare neuromuscular disorders can access the most effective emerging therapies.”
Help build the evidence
The pediatric natural history study
To prepare for pediatric clinical trials, researchers first need to document how CMT affects children over time. Families can contribute by joining GRIN, HNF’s patient registry, and completing the natural history study followed by the pediatric quality-of-life survey. It is confidential, and it is one of the most direct ways to move pediatric research forward.
Tip: once the natural history study and the health-and-development survey are complete, you can go straight to the pediatric CMT quality-of-life survey.
Family planning
Because CMT is inherited, many families want to understand the chance of passing it on. The inheritance pattern depends on the subtype: some forms are dominant, some recessive, and some X-linked. This is exactly why a confirmed genetic diagnosis is so useful.
Genetic counseling can walk you through what your subtype means for your family and what options exist. HNF’s CMT Genie connects you with telehealth genetic counselors who can help.
Where families connect
The CMT Summit, built for kids and families too
The annual HNF CMT Summit is part science conference, part family reunion. Alongside more than 30 science sessions, it makes real space for younger attendees and the people who love them.
- Youth Lounge, a dedicated hangout for kids and teens with CMT.
- CMT Storytime, gentle, age-appropriate sessions for the youngest attendees.
- Speed Friending, a low-pressure way to meet others who just get it.
- Adaptive Fashion Show, celebrating mobility devices, braces, and bold style.
- 30+ science sessions, plain-language updates straight from the researchers.
Recruiting pediatric families for the 2027 Summit
We are planning the 2027 Summit now and want children and teens with CMT, and their families, at the center of it. Add your family below and we will be in touch as dates, location, and registration are confirmed.
A note on hope, honestly
Most children with CMT do a great deal, and there is real reason for hope. Told honestly, that hope sits next to a hard fact: there is no approved disease-modifying therapy for CMT yet.
You are not powerless in the meantime. A cure is built from many families choosing to be counted, and a child added early becomes part of the evidence treatments are designed around. Confirming your child's type and joining the GRIN registry is a concrete step, and it moves the whole community forward.
Frequently asked questions
Can a child with CMT live a normal, active life?
Most children with CMT grow up to live full, active lives. With the right care team, therapy, and school support, the goal is simple: remove the barriers and keep the childhood. Progression varies a lot by subtype and by child, so no one can promise a single path, but full loss of walking is not the typical one.
Will my child need mobility aids or braces?
Some children use ankle-foot braces (AFOs) to improve stability and reduce trips, and a brace is not a sign that things are getting worse. It simply does the work a weakened muscle cannot, so a child can keep up, fall less, and tire less. Many children need little or no bracing. It depends on the subtype and on each child.
How do I get my child the right support at school?
A 504 plan (accommodations under federal disability law) or an IEP (Individualized Education Program, a special-education plan) can secure extra time, mobility help, seating, physical-education adjustments, and rest. Documentation from your child’s care team makes the case.
Should my child get genetic testing?
Confirming the subtype with genetic testing sharpens every decision that follows: it flags medications to avoid, helps the care team anticipate needs, and tells you which studies your child may qualify for. HNF’s CMT Genie supports patient-initiated genetic testing with telehealth genetic counseling.
Will activity make my child’s CMT worse?
Usually the opposite. Appropriate, low-impact movement helps maintain strength, flexibility, and confidence. A physical therapist who knows CMT can tailor a program that builds ability without overworking already-vulnerable muscles.
Next steps for your family
Two moves matter most: confirm your child’s subtype, and add their experience to the research that will shape the next generation of treatments.
