Clinical usability of a stability-based package using visualisation: a retrospective analysis

The utility of a new clinical system and user interaction, are important given that these may influence clinical use and incorporation into routine practice, as well as patient experience and engagement. As a result, rehabilitative outcome will be affected [1]. The stability-based package was designed and developed as a hybrid tool to enhance rehabilitative outcomes and experience using a game-development approach. By incorporating optoelectronic cameras for accurate motion tracking, a cluster-based model, pointer calibration and visualisation software for a simplified user-interface and real-time feedback, the package focused on addressing complexity and time efficiency to create more clinically appropriate motion analysis system. The feasibility and efficacy of the package has already been reported [2]. This study aimed to retrospectively analyse the usability of the package with respect to time efficiency. A retrospective analysis was completed to eliminate bias of completing training quickly, which would have shifted central attention away from the participant. This aimed to achieve an unbiased representation of the system usability for clinical practice.
