New method for the estimation of the number of motor units in a muscle: 2. Duchenne, limb-girdle and facioscapulohumeral, and myotonic muscular dystrophies. Issue 11 (November 1974) - Ballantyne, John P.
Abstract : The results of the application of a computerized method for the estimation of motor unit numbers in the human extensor digitorum brevis are presented. In patients with Duchenne and limb-girdle and facioscapulohumeral muscular dystrophies, motor unit numbers are within the normal range, but are significantly reduced in myotonic muscular dystrophy.
