Hemiplegic patients often have poor symmetrical sitting balance. Therapeutic techniques for such patients include weight shifting in sitting to encourage trunk movements and good posture.
A computerized sitting forceplate has been developed with the ability to measure weight distribution and it's changes. A normal sample of 69 subjects ranging in age from 20-79 years were studied on this forceplate. The purpose of this study was to gather standardized data for weight distribution in sitting and to compare the quantity of lateral weight shift with and without computer feedback. Subjects were randomly assigned to feedback first (FF) and feedback second (FS) groups. Visual feedback (consisting of a cross moving to the side of the· computer screen according to the amount of lateral force measured) had no significant effect on increasing lateral weight shift. A practice effect seemed to increase weight shift to the right more so than the left yet, there was no significant difference between right and left shifting indicating normals tend to shift symmetrically.
