Abstract
An isometric testing apparatus for performing isometric strength tests on individual muscles or joints of a patient includes a base, a seat coupled to the base, a vertical member coupled to the base, a horizontal arm coupled to the vertical member, and a force measuring device coupled to the horizontal arm. The base is configured for conserving space and allowing for placement proximal a corner. The chair is adjustably coupled to the base and may be adjusted to be located within the testing area, outside the testing area, and adjacent the testing area so that the chair may be used as needed or moved out of the way. The force measuring device is adjustably coupled to the base through the horizontal arm and vertical member and is horizontally and vertically adjustable for proper placement of the force measuring device. The force measuring device is pivotally mounted to the horizontal arm and pivots in a vertical plane to correct for any deflection of the vertical arm. The seat is pivotally coupled to the base and the force measuring devise is rotatably coupled to the base so that the seat may be pivoted and the force measuring device rotated so that the patient's joint line of action…
