RESUMO

In the adductor pollicis muscle of patients with limb-girdle and facioscapulohumeral muscular dystrophies and possible carriers of Duchenne type muscular dystrophy, abnormal active state properties were found at the time when there was no alteration of needle electromyography and evoked muscle action potentials. Adrenaline induced a marked reduction of incomplete tetanus via beta receptors without change in neuromuscular transmission.
