The Baseline Absolute+ Axis Goniometer is a digital and metal 9 inch goniometer with a 180 degree LCD scale and two bubble levels.
The Baseline Absolute+Axis goniometer establishes a "true" vertical or horizontal to the start point of a measurement. Many goniometric measurements require one arm of the goniometer to be positioned either horizontally or vertically. The other arm is then lined-up with the patient's body part. Until now, the practitioner had to "assume" or "eyeball" the vertical or horizontal position. This interpolation is often incorrect and introduces measurement error. The Baseline 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.
