The relationship between different foot sensations and balance performance during sensory organization test
Beeler, Amanda Faye
The relationship between sensory inputs from the foot and ankle, and postural control is not well established. The purpose of this study was to investigate the relationship between somatosensation of different sites of the feet and postural control. Tactile sense and vibration thresholds at eight different sites of both feet and ankle joint position sense were measured and correlated with the normalized path length of center of pressure (COP) and center of gravity (COG) during the sensory organization test (SOT). Eleven healthy adults (21 ± 1 years old, 4 females and 7 males) participated in the study. Study procedures consisted of measuring several somatosensory inputs (ankle joint position sense, vibration threshold, and tactile sensitivity) and performing the SOT. The results suggested that sensory inputs from several sites of the feet correlate to normalized path length of COP and COG movement during SOT and ABC, DHI and FGA in young healthy adults whom are right leg dominant. Our data suggested the right fifth metatarsal and medial malleolus appeared several times in different SOT condition and functional assessment scales. The joint position sense on the dominant foot might play a critical role during functional activities.
