[Postural synergy disorders in local brain lesions].
The electrical activity of the muscles of the legs and trunk was examined in 84 patients with verified (primarily neoplastic) affections of the brain. The patients were in the standing posture and were asked to make a voluntary movement (to raise an arm). The examinations showed that in patients with one hemisphere affected the posture synergy of the muscles was disturbed in both halves of the body. This was regarded as a consequence of a dysfunction in the so-called secondary, higher motor zones of the brain. The disturbances of the premovement activation of the muscles in both halves of the body were found to be significant only in cases of frontal lobe affections. This was confirmed by restoration of the posture synergy after successful ablation of the tumour.
