Abstract
We are interested here in the systems controlling both tonic innervation and stiffness of arm and hand muscles. Stereotactic interventions for treatment of pathological hyperkinesias provide the unique chance to investigate sensory motor systems in alert man. In addition, such physiological investigation may serve to improve functional neurosurgery. There are two interesting phenomena following therapeutic lesions:
-
1.
Decreased muscle stiffness, i.e. the resistance of the relaxed muscle to passive stretch is diminished.
-
2.
Failure in load compensation, e.g. holding the arm against gravity, controlled only by sensory feedback without visual control or during contraction against external load.
