[Cerebral control over locomotor function in occupational hand disease caused by local muscular overstrain].

Predominant orientation of local muscular load to proximal or distal portions of shoulders and upper limbs considerably influences features of changes in brain functions and blood supply. Characteristic for plasterers, localization of myogeloses in upper part of trapezium muscles causes not only impaired vertebrobasillar circulation, but also venous cerebral stasis and caudal medullar dysfunction. Clinical symptoms are vestibular disorders, depressed functions of hearing, chronic venous cerebral congestion, posture-tonic disorders. Local loads on distal portions of limbs have other mechanisms of cerebral and peripheral disorders.
