Paragraph Number

92

In certain embodiments, the face can include numbers that identify different measures of a balance status. In one embodiment, the dial 170 includes marks for angles ranging from -5 degrees to +5 degrees with 0 degrees representing a balanced condition. As the superior plate 118 and/or pivot plate 148 pivot or rotate about the pin 158, the rotation is measured by and conveyed to the balance indicator 126. Movement of the balance indicator 126 transfers to the needle 172 and moves the needle 172 to point toward a mark on the face that reflects the balance status. Rotation of the superior plate 118 or the inferior plate 120, about an anterior-posterior axis 116 of a patient, moves the needle 172 to point toward a mark on the face of the dial that reflects the orientation of the plates.
