finger pinch grip force being measuredAbstract: In the process of operating controls or performing activities of daily living, a variety of pinch grips get used e.g., a lateral (key) pinch, pulp pinch, thumb-forefinger tip pinch, palmar pinch. The universal design of hand-operated products and environmental features should apply an understanding of the gripping abilities of the broadest range of potential users, including individuals with disabilities.
