Finger Dynamics designs and manufactures precision exercise equipment used to improve performance, prevent injury, and rehabilitate the musculoskeletal system of the hand, wrist, and forearm that control finger and thumb movements.

Torque equals force times distance (T = f X d). The efficacy of our products is based on the lever, a simple machine that produces increased weight load the greater the distance the force or weight is from its fulcrum or pivot point. We measure weight in fractional ounces and grams, combining human biomechanics with physics.
