[Neuromuscular reactions to passive movements of the arm in patients with reactive states].

The results of clinical and physiological investigation of motor activity in 30 patients with various forms of reactive states with motor inhibition are discussed. Muscular tone changes and polymorphic neurologic signs were common for all the patients. Electromyography and mechanography revealed muscular dystonia, spasticity, rigidity and different responses to muscle stretching. All pathologic organic-like signs disappeared while clinical conditions of neurotic patients improved, hence, these are regarded as functional in nature.
