Most Charcot-Marie-Tooth (CMT) patients experience mild handgrip impairment, requiring basic advice. However, over 20% face severe deficits needing intensive rehabilitation or impacting daily living independence.

Area of Science:

  • Neurology
  • Genetics
  • Rehabilitation Medicine

Background:

  • Charcot-Marie-Tooth (CMT) disease is a progressive genetic neuropathy impacting peripheral nerves.
  • It leads to muscle weakness in extremities, affecting ambulation and handgrip function.
  • A new 4-stage classification system assesses handgrip impairment severity.

Purpose of the Study:

  • To determine the prevalence of each handgrip impairment stage in a large cohort of CMT patients.
  • To evaluate the distribution of clinical severity in demyelinating and axonal CMT subtypes.
  • To inform clinical evaluation and rehabilitation strategies for handgrip deficits.

Main Methods:

  • Examined 248 non-operated hands for specific pinch and grasp capabilities.
  • Classified each hand into one of the four established stages of handgrip impairment.

Related Experiment Videos

  • Determined the frequency distribution of patients across the four stages.

    • Main Results:

    • Stage 1 (mild impairment) was observed in 75.4% of hands.
    • Stage 2 (moderate impairment) affected 9.7% of hands.
    • Stages 3 (severe) and 4 (very severe) affected 10.9% and 4% of hands, respectively.

    Conclusions:

    • The majority of CMT patients exhibit mild handgrip deficits, necessitating preventative measures.
    • A significant minority (over 20%) present with severe impairment requiring structured rehabilitation.
    • A small percentage of patients experience profound handgrip loss, severely limiting daily activities.
