Variation of ankle biomechanical property according to vibro-perception threshold and vibration frequency

The purpose of this study was to investigate the biomechanics according to vibro-perception threshold and vibration frequency during gait.
To this end, the vibro-perception threshold by the vibration frequency was measured and vibration was applied based on these findings during gait. To analyze the biomechanical property variations in the ankle joints during gait, a three-dimensional movement analysis system and biomechanical software was used. We analyzed the angles, moment and power of the ankle joints.
The vibro-perception threshold measurement showed that the perception threshold differed depending on the area of stimulation and vibration frequency. The variations in biomechanical properties due to stimulation of the subperception threshold intensity (80%) was similar to those at the perception threshold. Also, the variations in biomechanical properties due to stimulation were dependent on the vibration frequency.
This indicates that vibratory stimulation could trigger variations in biomechanical properties in a manner dependent on the characteristics of the vibratory stimulation.
