Original Research Feasibility of an Exoskeleton-Based Interactive Video Game System for Upper Extremity Burn Contractures

Background: Burn contractures are common and difficult to treat. Measuring continuous joint motion would inform the assessment of contracture interventions; however, it is not standard clinical practice. This study examines use of an interactive gaming system to measure continuous joint motion data. Objective: To assess the usability of an exoskeleton-based interactive gaming system in the rehabilitation of upper extremity burn contractures. Design: Feasibility study. Setting: Eight subjects with a history of burn injury and upper extremity contractures were recruited from the outpatient clinic of a regional inpatient rehabilitation facility. Methods: Subjects used an exoskeleton-based interactive gaming system to play 4 different video games. Continuous joint motion data were collected at the shoulder and elbow during game play. Main Outcome Measures: Visual analog scale for engagement, difficulty and comfort. Angular range of motion by subject, joint, and game.
