ABSTRACT:
A device for testing a shoulder of a patient includes a base with a pivot arm extending therefrom. A force indicator is located at the extended end of the arm and a movement indicator is mounted on the device at its base. In order to prepare for the operation of the device, the patient is placed to effectively hold the shoulder stationary. The base of the device is then positioned on the clavicle and the force indicator is positioned on the humeral head. Preferably, the force indicator is secured to the shoulder with a strap. To test the shoulder once the device is properly positioned on the patient, a force is applied to the force indicator. This applied force is transferred directly to the humeral head and the results of its application are recorded. Specifically, the magnitude of the applied force is measured by the force indicator and the movement of the humeral head relative to the clavicle is measured by the movement indicator. The recorded measurements are then used for diagnostic purposes.
