(RM-Biorescue) Saccadic Eye Movement Improves Plantar Sensation and Postural
Vision, proprioception and plantar sensation contribute to the control of postural balance (PB). Reduced
plantar sensation alters postural response and is at an increased risk of fall, and eye movements reduce
the postural sway. Therefore, the aim of this study was to study the improvement of plantar sensation and
PB after saccadic eye movement (SEM) and pursuit eye movement (PEM) in community-dwelling elderly
women. Participants (104 females; 75.11 ± 6.25 years) were randomly allocated into the SEM group (n
= 52) and PEM groups (n = 52). The SEM group performed eye fixation and SEM for 5 minutes, and the
PEM group performed eye fixation and PEM for 5 minutes. The plantar sensation was measured according
to the plantar surface area of the feet in contact with the floor surface before and after the intervention.
Before and after SEM and PEM with the eyes open and closed, PB was measured as the area (mm2),
length (cm), and velocity (cm/s) of the fluctuation of the center of pressure (COP). The plantar sensation of
both feet improved in both groups (p < 0.01). Significant decreases in the area, length, and velocity of the
COP were observed in the eye open and close in both groups (p < 0.01). The length and velocity of the
COP significantly decreased in the SEM group compared to the PEM group (p < 0.05). In conclusion, SEM
and PEM are effective interventions for improving plantar sensation and PB in elderly women, with greater
PB improvement after SEM.
