Baseline Absolute+Axis Hi-Res Goniometer, 12 Inch

The Baseline Absolute+Axis (AA) Hi-Res Goniometer eliminates measurement variability by establishing a true vertical or horizontal reference, removing the need to assume or eyeball alignment during range-of-motion assessment. The integral absolute vertical and horizontal levels are permanently incorporated into the goniometer body, allowing the practitioner to concentrate on correct placement of the goniometer arm and the patient’s body position rather than estimating alignment. The hi-res scale provides precise degree markings for accurate measurement documentation. 12 inch. Sold individually.

Ideal For

Physical therapists, occupational therapists, and athletic trainers who perform range-of-motion assessments as part of initial evaluation, progress monitoring, and discharge documentation will find the Baseline AA goniometer’s built-in absolute levels significantly reduce the inter-rater and intra-rater variability that commonly affects goniometric measurements, improving the reliability and reproducibility of ROM data across clinicians and sessions. Clinicians who measure shoulder and hip rotation, cervical ROM, and hamstring flexibility — measurements that are particularly susceptible to alignment error when using standard goniometers — will find the AA design’s true vertical and horizontal reference eliminates the most common source of measurement error in these assessments. Rehabilitation programs and outpatient therapy clinics that use standardized outcome measures and need consistent, reproducible ROM data across multiple clinicians and patient visits will find the AA goniometer supports measurement standardization without requiring additional alignment tools or positioning aids. Sports medicine clinicians and orthopedic physical therapists who document ROM as part of return-to-sport and return-to-work assessments will find the hi-res scale and reduced measurement variability support more defensible, accurate documentation of functional ROM milestones. Clinical educators and physical therapy programs that teach goniometric measurement technique to students and residents will find the AA goniometer a valuable teaching tool for demonstrating the impact of alignment error on measurement accuracy and the importance of establishing a true reference before measuring.

Frequently Asked Questions

What does Absolute+Axis mean?
The Absolute+Axis (AA) designation refers to the built-in integral levels that establish a true absolute vertical or horizontal reference axis before measurement. This eliminates the need for the clinician to visually estimate or assume the correct alignment of the stationary arm, which is the most common source of variability in standard goniometric measurement.

What is the difference between a standard goniometer and the AA Hi-Res goniometer?
A standard goniometer requires the clinician to visually align the stationary arm with an anatomical landmark or estimated reference, which introduces variability between measurements and between clinicians. The AA goniometer’s built-in levels allow the clinician to establish a true vertical or horizontal reference objectively, reducing measurement variability and improving reproducibility.

What joint measurements is this goniometer best suited for?
The AA goniometer is specifically designed to improve measurements of shoulder and hip rotation (internal and external), cervical flexion, extension, rotation, and side bending, hamstring flexibility, and active ROM assessments where establishing a true vertical or horizontal reference is critical for measurement accuracy.

Is this goniometer sold as a pair or individually?
This listing is for one goniometer sold individually.
