[Function of sensorimotor equilibrium function in elderly patients on the basis of vestibular evoked myogenic potentials (m.p.p.w.)].
Observed elderly had general weakness of motor and mental function. The slower reactions to environment stimulus in elderly above 60 years result first of all from weakness of sensory receptors as visible, hearing, smell and taste. In this age group disturbing of balance system function demonstrated vertigo, dizziness, darkness of visible, disequilibrium was more encountered. Up to now there is not specified that "presbyequilibrium" (presbyvertigo, presbyastasis) as physiology ageing process causes this condition or destructive processes, infections, vascular insufficiency and neoplastic processes in inner ear and acoustic tracts and centres. Vestibular symptoms often are related to age by the doctors so for that reason basic and sometimes dangerous disease may be missed. Proposition of this paper is estimation of reflex function of balance system in connection with ageing process. To this end VEMPs were used and latencies and amplitudes of ipsilateral and contralateral VEMP recordings were calculated in young and elderly groups. Lower reflex efficiency in elderly disclosed longer latencies and lower aptitudes of p14 n21 of VEMPs than young people but without significant differences.
