Efectos posturales inmediatos de la amplificación mecanoceptiva en niños con disfunciones neuromotrices, valorados mediante una plataforma de presiones Wii Balance Board. Estudio consecutivo no controlado

Abstract

Introduction Neurological disorders are a common cause of child disability. Neuromotor dysfunctions are currently being clinically faced through orthopedic, pharmacological and physiotherapeutic treatments. Therapeutic vibrations are studied to know their trophic and neuromodulator effects. Objective To observe the changes related to postural control in cases of infantile neuromotor dysfunction after the application of ecological vibratory stimuli, measured with a force platform. Patients and methods Consecutive uncontrolled study. 15 subjects with motor disabilities and a mean age of 9±3.4 years were assessed in static standing using the Wii Balance Board platform before and after a single dose of mechanoceptive amplification (AM). Variables of the center of pressures were analyzed: mean position, mean excursion, amplitude and path length. Results The pre-MA center of pressures mean position of the ensemble was further from the anatomical center on the frontal axis than on the sagittal axis in a statistically significant way (p=.041) and subjects showed significantly longer mediolateral path lengths of the center of pressures (p=.001) than the anteroposterior path lengths. Post-AM there were significant increases for the total mean excursion variable (p=.015), for the amplitude on the frontal axis (p=.010), and for the path length both in the total (p=.005) as in the partials of axes frontal (p=.006) and sagittal (p=.004). At the observational level, the mean sagittal position of the ensemble was posteriorized while the mean frontal position of the ensemble approached toward the center, with a high correlation between relocation/excursion and amplitude/path length. Conclusion The subjects obtained a postural rebalancing tending toward posteriorization and toward the stimulated lower limb after MA.
