Baseline Absolute+Axis Goniometer Attachment 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 (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.
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.
