Ab. No. 59 Reliability of Dual Weighing Scale Biofeedback System (DWSBS), a New Apparatus for Assessment and Training of Weight Bearing Asymmetry (WBA)

Abstract

Introduction: Weight bearing asymmetry leads to major impact on gait execution strategies post neurological conditions. A cheap and cost-effective apparatus which can be incorporated in routine use with less costs per session, will help treat asymmetry and enhance a near normal gait pattern with reduction in compensatory strategies. Introduction of new, cost effective and reliable apparatus against costly and cumbersome apparatus which is portable and needs less clinical expertise to use. Secondary objective is to target, population with neurological issues where weight bearing asymmetry leads to major gait disturbances. Methods: 56 Normal Healthy individuals (45-65 years) Instrumentation of DWSBS, by using 2 platforms for standing, measuring 12 x 12 inches each, embedded on a single platform, placed at a distance of 2 centimetres between them. A common display with digital output for both weighing scale was used. Reliability testing - 56 healthy individuals without any balance issues recruited and asked to stand bipedally, with eyes open on each of 2 weighing scales separately;post 3 trials, average of reading were documented. Data collected by 2 raters (Rater 1- reading on day 1 and 3; Rater 2 - reading on day 2) were analyzed using Cronbach’s alfa test in SPSS version 23 software. Result: Excellent reliability for Intrarater and interrater testing as per ICC values 0.9. neck ROM. Conclusion: The new apparatus has proven to be reliable and is fit to be tested for validity. Implications: DWSBS will help reduce to cost and execution-based burden for weight bearing asymmetry training.
