Ergonomic Evaluation Methods for Hand Exoskeleton Prototypes: A Scoping Study

Abstract

Hand function is essential for daily activities, but neurological, muscular, and environmental limitations can impede hand mobility. Robotic hand exoskeletons offer promising assistance for these impairments, though a standardised evaluation method for their effectiveness is lacking. This study addresses this gap by conducting a scoping review to explore current ergonomic evaluation methods for hand exoskeleton prototypes. The primary objective is to identify and analyse the tests used to assess technical performance and user experience, aiming to establish a comprehensive framework for future assessments. A research question guided the research: “What ergonomic evaluation tests are applied to assess the performance and effectiveness of hand exoskeleton prototypes for assisting with daily tasks?” The review analysed diverse evaluation methods, including physiological, kinematic, and kinetic metrics, alongside subjective user surveys. Usability assessments evaluate safety, comfort, and overall experience, while biomechanical testing explores muscle activity and range of motion, with electromyography (EMG) used to compare muscle activity with and without exoskeleton support. The study emphasises the need for a comprehensive and standardised approach to evaluate hand exoskeletons, integrating technical performance and user experience metrics to ensure effective and user-friendly designs.
