Abstract

The goal of this project was to quantify the postural changes induced by yoked prisms after a period of adaptive wear between two groups, one sitting and reading while the other was continually walking. The project included 36 randomly selected subjects ranging in age from 21 to 28. Testing involved measurements to quantify the immediate and short term effects of vertical yoked prism wear on the center of balance as measured by the Chattex Balance System™. Our study noted immediate significant changes in body posture when prisms were first placed on subjects. After short time adaptation, both reading and walking groups showed a return to habitual posture with no difference in adaptation between groups. No significant "rebound" or after-effect of prism wear was measured immeidately after prims removal. 1
