Abstract
This investigation examined the postural-sway response of a matched group of learning-disabled and normal subjects. The subjects were evaluated on a force platform both with their eyes open and with their eyes closed. Four dependent variables, the measures of sway, were subjected to multivariate analysis of variance (MANOVA), with group as the independent variable. The analysis revealed F= 4.25 (p <.07). The Univariate F test revealed Root Mean Square Y (EC) to be significant at p <. 002. A t test revealed Romberg Y to be significant at p <. 026. The results indicated a significant difference in postural sway between the two groups. The learning-disabled group appeared to be using visual input to compensate for postural problems and experiencing significant difficulty controlling posture in an anterior/posterior direction, especially with their eyes closed. Limitations of the study are discussed, and implications for occupational therapy and future research are outlined.
