Abstract
The device is a portable non-invasive device which uses purely mechanical components to measure the hardness of muscle or muscle compartment. It is comprised of two long members coupled rotationally in a scissor-like manner with the handles on one side of the hinge and the graspers on the other side. Built onto the device is a mechanism to modulate the extent of compression of the muscle via a calibrated block situated across the members so that a predetermined amount of compression of the muscle will occur as the distance between the handles is decreased manually by the operator. The force necessary to compress the muscle by the set predetermined amount is measured by the distention of the spring mechanism attached to the handle.
