Abstract

An orthotic apparatus for use in providing improved range of motion is provided which allows the amount of stretch to be hydraulically powered and measured by the device, but controlled by the user. Because the apparatus accurately calculates the amount of stretch, the user, together with the user'"'"'s physician and therapist, can develop a rehabilitation plan based on accurate measurements. Progress is based on tangible results rather than the user'"'"'s ability to tolerate pain. This knowledge provides the incentive the user needs to work toward and achieve the user'"'"'s goal.
