Abstract

THE IMMEDIATE INFLUENCE OF WHOLE BODY VIBRATION ON PROPRIOCEPTIVE PRECISION Madill, Sean; Dakin, Chris Kinesiology & Health Science Dept., Utah State University, Logan, UT Exposure to whole-body vibration activates inertial and strain sensitive sensory receptors over our entire body, whose information is used to analyze our environment and coordinate movement. Prolonged exposure to whole body vibration has previously been shown to reduce the responsiveness of these receptors resulting in decreased sense of joint position. However, conflicting results have been observed when the duration of vibration exposure is significantly shorter, suggesting that sensory adaptation may be dependent on the duration of exposure. Therefore, we hypothesized that adaptation of the sensory receptors involved in proprioceptive acuity would be diminished following prolonged exposure to whole-body vibration. Twenty-five adults completed a between ankle joint matching task before and immediately following a 20-minute whole-body vibration session and a control session of 20 minutes of standing near, but not on the vibration plate. The joint matching task consisted of moving the participants left ankle to one of four selected angles (10°, 15°, 20°, 25°), having them hold it at that position and match the angle with their right ankle. The foot was positioned at each angle three times (12 trials total) to complete the matching task. The set joint angle and “matched” joint angles were measured using a digital goniometer. Analysis of the baseline and post vibration scores showed that there was no main effect when the scores were combined across all angles. These results suggest that the duration of the vibration may not play a significant role in influencing proprioceptive acuity.
