ABSTRACT:
An instrumented orthopedic restraining device is provided. The device includes an ambulatory housing, including first and second distal end portions, and restraining means for restraining movement of the first and second distal end portions relative to one another. The restraining device preferably includes an elongated restraining bar equipped with a stress sensing mechanism for sensing stress on the restraining bar. A control unit is provided for indicating sensed stress based upon outputs from the stress sensing mechanism. Preferred embodiments include a plurality of strain gauges attached to the elongated restraining bar and interconnected with the control unit which preferably includes a recording mechanism and a microprocessor mechanism. The elongated restraining bar alternately includes an adjustable hinge interconnecting distal end sections of the elongated restraining bar, wherein the angle between the respective distal end sections can be adjusted relative to one another. The adjustable hinge is preferably an electromechanical hinge which can be at least partially controlled by software read by the microprocessor mechanism. Methods of using embodiments of the present invention are also disclosed.
