Abstract
We investigated the accuracy and reliability of observational kinematic gait assessments performed via a low bandwidth Internet link 18 kbit s and a higher speed Internet link 128 kbit s Twenty four subjects were randomized to either bandwidth group Gait was assessed with the Gait Assessment Rating Scale GARS in the traditional manner which is from video recordings and with repeated measurements via the online method Online assessment was found to provide as accurate a measure of gait performance as the traditional assessment limits of agreementUnder1 GARS point intraclass correlation coefficient ICC 0 96 regardless of the speed of the Internet connection The online assessment also demonstrated high intra rater ICC 0 96 and inter rater ICC 0 92 reliability Low bandwidth telerehabilitation applications appear to be feasible via the Internet
