ABSTRACT:
A grip force assessment device, method and system that can provide a grip force map image presenting a detailed image of the complex grip capability/capacity of a human hand including the palm and all digits improving over existing assessment systems and their attendant inaccuracy, poor reliability, and lack of meaningful clinical relevance. The grip force assessment system includes a grip force transducer including a high-resolution tactile array that produces a high-resolution grip force signal. A processing device processes, analyzes and outputs grip force data. A display provides a grip force map image showing distribution of individual finger function relative to entire hand function. The grip force transducer includes a high-resolution tactile sensor wherein the greatest distance between adjacent pressure sensing nodes is in the range of 1.0 mm to 10.0 mm.
