    • A method for the assessment of various properties of bone is provided. The method includes applying a pair of ultrasound transducers to skin on opposite sides of the bone and generating an ultrasound signal, and directing the signal through both the bone and a known medium to obtain a bone output singal and a reference signal. The method further includes establishing a set of parameters associated with the bone output signal and a set of parameters associated with the reference signal, and then subjeting the two sets of parameters to comparative analysis in order to obtain the desired bone property. An apparatus for the assessment of various properties of bone is also provided. The apparatus includes a pair of ultrasound transducers (16, 18) which may be single element transducers or array transducers in any combination. The apparatus further includes various computer hardware components (20, 22) and computer software (34) for generating and directing the ultrasound signal, establishing the parameter sets and performing the comparative analysis.

    • The present invention provides continuous passive motion (CPM) devices for joints. An ankle CPM device includes a lower leg support attached at its lower end to a semi-circular track. An actuator slides along the track and can be locked in any desired position on the track. A shaft is pivotally connected at one end thereof to the actuator and a shoe is attached at the other end thereof. When the actuator is positioned at the bottom of the track, the ankle joint of the patient undergoes inversion/eversion motion. When the motor housing is rotated 90° and positioned near the top of the track plantar/dorsi, flexion movement is obtained. A combination of both types of joint movement are obtained for the actuator in intermediate positions. A wrist CPM device includes a brace for the forearm attached to a semi-circular track on which an actuator is mounted. A hand grip is mounted on a semi-circular bracket and a shaft extends between the actuator and a coupling slidably mounted on the semi-circular bracket. With the actuator positioned below the forearm, when the actuator pivots the shaft the wrist joint undergoes ulnar/radial deviation movement and when the motor is rotated 90° and positioned at the side of the arm, extension/flexion movement of the wrist joint is obtained. Positioning the actuator in intermediate positions produces a wrist movement which is a combination of extension/flexion and ulnar/radial deviation of the wrist joint.
