[Effect of mechanic stimulation of foot support zones during 7-day dry immersion on alterations of ocular saccades kinematics associated with immersion].
Purpose of the investigation was to evaluate how daily sessions of mechanic stimulation (MS) of foot support zones applied to mitigate the effects of lack of support loading on the postural muscles influence ocular saccades during prolonged support deprivation. According to the experimental protocol, before and immediately after 7-day dry immersion, 4 control and 4 MC human subjects (experimental group) implemented the test of rapid blanking light target appearing on the visual field periphery. Eye motions were detected using infrared images obtained at 200 Hz. Analysis of normalized and consolidated data showed that MC of foot support zones moderated significantly alterations in ocular saccade kinematics associated with support load deprivation confirmed by recruitment of support afferentation in sensory input to mechanisms of ocular saccade generation.
