  • SPINAL ASSESSMENT SYSTEM
    Publication number: 20190083027
    Abstract: A device for measuring spinal stiffness comprises a frame-work supporting a roller that is rolled over the surface of the back. The device creates and records a trajectory across a subject, using a control board and the roller, and moves the roller along the trajectory while applying a force to the subject using the roller and records displacement of the object in the direction of the force. A stiffness map is created using displacement as a function of force. Motors may be used to move the roller through three axes.

  • Biological skeletal system monitoring
    Patent number: 9161709
    Abstract: A method of monitoring target tissue of a biological skeletal system. The method comprises applying a mechanical excitation to a portion of the biological skeletal system to generate a mechanical wave that passes through the target tissue, the target tissue modulating the mechanical wave to produce a response of the target tissue to the mechanical wave, measuring the response; and determining structural or functional status of the target tissue from the response. A system for applying the method is also provided.
