title: The stretch reflex in the Eaton Lambert syndrome, myasthenia gravis and myotonic dystrophy.
abstract: The stretch reflex at rest and after muscle work was studied in three cases of Eaton Lambert syndrome. After muscle work a potentiation of the stretch reflex was demonstrated clinically and electrophysiologically. The presence of muscle stretch reflexes and their potentiation after muscle work was correlated with the clinical stage of the disease. The enhancement of the stretch reflex after voluntary effort was absent in normal subjects, myasthenia gravis and myotonic dystrophy.
