Absolute+ Axis Plastic Head Goniometer
Baseline Plastic Absolute+Axis Goniometer.
This goniometer has an integrated Absolute+Axis at the end of one arm. The Absolute+Axis (AA) 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 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.
