Pulmonary function and electromyographic study of respiratory muscles in myotonic dystrophy.

abstract：:Although conduction block indicates dysfunction of peripheral nerve, it may occur in patients with clinically typical motor neuron disease. There are no universally accepted criteria to identify conduction block, so diagnosis may be difficult. In some peripheral neuropathies, conduction block persists over long period...
