a
HMSN = hereditary motor and sensory neuropathy; MVC = maximum voluntary contraction (ie, peak torque); NA = not available; NMDs = neuromuscular diseases.
b
Seventeen individuals were unable to perform the measurement with the more affected limb because of muscle weakness.
c
Five patients with motor neuron diseases were included in the reliability assessment.
d
Three patients were not eligible for bilateral evaluation.
