Abstract: A handgrip device has a palm rest operable to engage with a palm of a user, a grip bar moveably coupled with the palm rest and operable to engage with one or more fingers of a user. One or more force transducers can be disposed between the palm rest and the grip bar to measure a compression rate and the return rate of the grip bar relative to the palm rest, and a data connection operable to communicate the compression rate and the return rate.
