Description
Baseline 12 Absolute+Axis Goniometer is a 12‑inch diagnostic instrument designed for objective range‑of‑motion (ROM) assessment. The circular protractor head provides a 0–180° scale with 1° graduations and is coupled to a straight 12‑inch arm that carries imperial and metric markings. Absolute+Axis technology eliminates estimation by establishing true vertical or horizontal references during measurement. Vertical and horizontal bubble levels are permanently integrated into both the circular head and the arm, promoting consistent alignment independent of practitioner technique.
Typical use cases include measuring shoulder and hip internal/external rotation, cervical flexion/extension, rotation and side bending, hamstring flexibility, and active ROM. The two-color baseline scale enhances visibility for quick setup and repeatable positioning, reducing variation when documenting patient posture and limb alignment. The instrument is designed for compatibility with standard clinical ROM protocols and patient assessments, delivering reproducible readings that support tracking progress over time.
