ABSTRACT:
A method and device are described for providing passive exercise treatment for increasing the amount, strength and proper anatomical distribution of bone in a patient suffering from a bone disorder. The method involves determining a value for impact load, impact rate, and treatment duration for the patient to provide treatment for the bone disorder, and repeatedly lifting the patient's heels a prescribed drop excursion and then allowing the patient's heels to drop from the prescribed drop excursion to impart the determined impact load at the determined impact rate for the determined treatment duration. The values for impact load, impact rate, and treatment duration are signals based upon the characteristics of the patient's skeletal tissue and ensure that an electrical signal generated in that tissue has certain characteristics. This method may be effected by a device with a pivoting platform, a pivoting lift lever linked to the pivoting platform, a cam follower located at a free end of the lift lever, a cam engaging the cam follower, and a motor rotatably coupled to the cam.
