  • Device for measuring lumbar spinal movement
    Patent number: 5400800
    Abstract: An improved device is described for measuring and registering lumbar spinal movement. The device, which is portable, is attached at an upper and lower portion of the lumbar region and measures multiple axis of motion by means of independent electric sensors. The device of the invention is an improvement over prior art devices because it provides appropriate compensation for errors induced through interaction of three axis only of rotational movement.

  • Device for inducing and registering imbalance
    Patent number: 5337757
    Abstract: A device is provided for registering and recording induced imbalance in a human subject. A horizontal platform is adapted for controlled, linear displacement in a horizontal plane to induce imbalance. Imbalance and response can be detected and recorded by means of electric contact shoes or other means.

  • Isoinertial lifting device
    Patent number: 5151071
    Abstract: An isoinertial lift machine is described which can be used to evaluate and train patients in the static and dynamic lift modes. The machine consists of an arm which can be positioned on a vertical column. At the end of the arm, various size attachments and handles can be attached. The arm also carries a force sensor that measures the forces applied to the handles. In the static mode, the arm is positioned at a desired height and locked in place. The patient lifts on the handle, and the force sensor registers the lifting force. Since the handle does not move during the lift, the mode is called static. In the dynamic mode, the arm/handle moves in the vertical direction during the lift. A resistance mechanism is used to resist the lifting force applied by the user at the handle. The resisting force is always pulling the arm down, both in the lifting and the lowering motion. The resisting force remains constant throughout the range of motion during lifting.

  • Isometric lifting device
    Patent number: 4972711
    Abstract: A device for measuring linear force which is converted to rotational force or torque. Initially, force is applied in a linear direction to a means for transmitting that force to a rotatable shaft where it is converted to rotational force which can be measured by a strain gauge. The device is mounted on a vertically adjustable column attached to a moveable base.
