Finger Dynamics Inc.
Precision exercise equipment for the human hand.
We design and manufacture instruments that improve performance, prevent injury, and rehabilitate the musculoskeletal system controlling finger and thumb movement.
The science
Torque equals force times distance.
The efficacy of our products is based on the lever — a simple machine that produces increased weight load the greater the distance the force is from its fulcrum or pivot point.
We measure weight in fractional ounces and grams, combining human biomechanics with physics to produce calibrated, repeatable resistance.
