| Summary: | 碩士 === 台北巿立體育學院 === 運動科學研究所 === 95 === The causes of the functional ankle instability are peroneal muscle weakness and proprioception deficits. Vibration might change the function of the sensory and motor system. High-frequency vibration has an effect on the spindle endings and afferents. Low-frequency whole-body vibration has the similar effect with the tendon vibration. To investigate the short-term effects of the sitting-position whole-body-vibration training on the proprioception in the functional unstable ankles, we had the subjects continued three days repeated measurements on the same time each day. We analyzed the data from the Cybex for the kinesthesia and the Balance master for the postural sway. The speed of the Center of Gravity (COG) sway had a significant difference in the time factor (P<0.01). No adverse effects were observed. The kinesthesia in the functionally unstable ankles is more sensitive than in the healthy ankles. The ankle proprioceptive information is altered by the ligaments injury. It would be appropriate for the central nerve system to rely on the more reliable information from the muscle/tendons of the ankle. Without the transmission of vibration to the vestibular system, the posture-sway was not affected.
