PENGARUH PES PLANUS PLANTARIS METATARSALIA TERHADAP STABILITAS POSTURAL VERTEBRA ATLET OLAHRAGA DENGAN WEIGHT-BEARING
Overuse activity is at risk of injury to the lower limb and will decrease curvature in the plantar arch. Sports athletes with continuous weight-bearing exercise activity will affect the curvature of the plantar, causing the malformation of the foot arch to become flatter (flatfoot). This condition is reported to affect postural stability during the move. This is a quantitative cross-sectional analytics study involving basketball athletes for all 47 subjects. Subject's foot arch index determined with footprint on the graph paper, followed by AMTI Accupower Force flatform posturography (force plate) as postural stability determintion. The examination is performed in static positition to determine body,s postural sway diameter of CoP on the base of support area while standing. The result revealed that 80,9% of subjects had flat plantar arch (pes planus plantaris). Footprint results showed majorities of basketball athletes having pes planus plantaris. The mean value of the postural sway diameter of CoP while standing (static) on the subject with pes planus plantaris have significant correlation on the postural stability. This condition will significantly affect postural stability in quite standing conditions.
