ABSTRACT
Balance control requires multiple system adjustment and coordination and is a necessity for daily activities. Due to its diverse nature of control to assess balance in a single parameter has been a problem as no one parameter describes its all component but Limit of stability (LOS) has been found to be more reliable by far. For this study a reaction board was used to test the limit of stability i.e. the maximum horizontal excursion an individual could perform in his/her base of support (BoS) just before falling. To apply this method of assessing balance in a clinical setting where force plate system affordability is not feasible the inter-rater and intra-rater reliability must be established for the same. For the purpose of study 10 healthy subjects were selected to test the inter-rater and intra-rater reliability at a week difference. The inter-rater reliability was found to have an acceptable reliability for anterior shift (0.78) and left lateral shift (0.78), good reliability for posterior shift (0.87) and poor reliability for right lateral shift (0.28).The intra-rater reliability was found to have good reliability for anterior shift (0.86) and posterior shift (0.82) and poor reliability for left lateral (0.35) and right lateral shift (0.44) and all the values are within 95% confidence interval with p= 0.05. Henceforth we conclude that reaction board can be used as a reliable tool to measure the anterior and posterior limits of stability of an individual.
