Differences in hand-muscle
strength/dexterity between dominant (DH) and non-dominant (NDH) hand in
Charcot-Marie-Tooth disease (CMT) are not well understood. PURPOSE OF THE STUDY:
To compare muscle strength/dexterity between DH and NDH and to correlate manual
dexterity, strength and sensory function. METHODS: Thirty CMT
patients were studied using functional muscle testing (FMT) and strength
(dynamometry), dexterity (the Nine Hole Peg Test [NHPT]), and Jebsen-Taylor Hand
Function [JTT]), and sensory function (the Nottingham Sensory Assessment [NSA]).
RESULTS: Scores were worse for DH than NDH on FMT (p = 0.043) and NHPT (p =
0.014) but not on JTT (p = 0.098), handgrip strength (p = 0.710) or tripod pinch
(p = 0.645). NSA did not correlate significantly with any tests (p's0.05).
CONCLUSIONS: In CMT disease, DH appears more impaired than NDH in terms of
function and dexterity. Greater muscle weakness in DH may also emerge as CMT progresses. LEVEL OF EVIDENCE: 3b.
