Baseline® Plastic Absolute+Axis® Goniometer - 360 Degree Head - 12 inch Arms has an integrated Absolute+Axis® at the end of one arm.
The Absolute+Axis (AA) goniometer removes the assume and eyeball by establishing a "true" vertical or horizontal to the start point of a measurement. The Absolute+Axis goniometer removes measurement variability and allows the practitioner to concentrate on correct placement of the other goniometer arm and the patient's body position. The integral absolute vertical and horizontal levels are permanently incorporated. Some measurements the AA goniometer is designed to improve are: shoulder and hip rotation (internal external); cervical flexion, extension, rotation, and side bending; hamstring flexibility; and active Range Of Motion.
