Digital Dynamometer: A New Technology to Measure the Palm Grip Force-Time Curve

The palm grip measurement is helpful in upper limb rehabilitation. This paper focus on the presentation of a new technology to measure palm grip and show graphically the Force-Time response. A hand Digital Dynamometer was partially developed using load cell techniques. Its mechanical design will follow a commercial equivalent tool; its interface communicates with dynamometer hardware and its program has been developed for both Android and iOS operational systems. The load cells do not have accuracy error after calibration, proving to be better over other technologies. The devised solution will help physiotherapists monitor their patients in upper limb rehabilitation programs.
