Abstract:
Handgrip strength is an important medical indicator of a person's health and a predictor of morbidity and mortality. Testing is performed with either a hydraulic or digital hand-held dynamometer, typically only measuring maximum handgrip force. We developed a sensor-integrated dynamometer that automatically and wirelessly captures the dynamic handgrip force strength, which is displayed as a graph and accessible on a website. In addition, the system analyzes the collected data and provides additional graphs, including the amount of force exerted over time, change in the rate of handgrip force, duration for each hand squeeze, time resting between each hand squeeze, total time lapse for three hand squeezes, and the detection of hand tremors. These data can give doctors significant insight into a patient's hand strength and overall health.
