Abstract

The present invention relates to a device and method for measuring force, primarily due to fatigue. In one embodiment, a finger fatigue measuring system is provided which measures the force output from fingers while the fingers are repetitively generating forces as the strike a keyboard. Force profiles of the fingers are generated from the measurements and evaluated for fatigue. The system can be used clinically to evaluate patients, to ascertain the effectiveness of clinical intervention, pre-employment screening, to assist in minimizing the incidence of repetitive stress injuries at the keyboard, mouse, joystick, and to monitor effectiveness of various finger strengthening systems. The system can also be used in a variety of different applications adapted for measuring forces produced during performance of repetitive motions.
