Baseline (Dupl)Attachment For Absolute+Axis Goniometer

The Baseline Attachment for Absolute+Axis Goniometer is a removable attachment piece to be attached to any 12" plastic goniometer (sold separately). When attached to the end of one goniometer arm, the standard goniometer is transformed into an Absolute+Axis goniometer. The 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.
