Finger-force measurement-device for hand rehabilitation

The purpose was to develop an extension fingerforce measurement device, and investigate the intraindividual repeatability. The design of the measuring device allows single finger force and whole hand measurements, and the repeatability error on extension finger forces was measured, both on the whole hand, as well as on individual fingers. The tests showed that a repeatability error of less then 15 % can be achieved for single finger measurements and less then 21 % for whole hand measurements.
