Baseline Goniometer, 12 Inch, 360 Degree, Plastic

The Baseline 12-Inch 360-Degree Plastic Goniometer is a clear, transparent instrument designed for accurate range-of-motion measurement in clinical and rehabilitation settings. The transparent plastic construction allows direct observation of the joint's axis of motion and its range of movement during assessment. The 360-degree head features three scales calibrated to the ISOM (International Standards of Measurement, STFR) system, and one arm includes a linear scale in both inches and centimeters for additional measurement versatility. Readings are taken in 1-degree increments for precise documentation.

Ideal For

This goniometer is an excellent choice for physical therapists, occupational therapists, and athletic trainers who need a reliable, ISOM-compatible instrument for routine range-of-motion assessments across all major joints. It is well-suited for clinical settings where multiple practitioners share instruments and need a clearly readable, standardized tool that produces consistent results. The transparent design makes it particularly effective for teaching and student training environments where the instructor needs to demonstrate joint axis alignment and measurement technique visually. Anyone seeking a durable, affordable, full-featured plastic goniometer for daily clinical use will find the Baseline 360-degree model a dependable and practical choice.

Frequently Asked Questions

What does the 360-degree head allow me to measure?
The 360-degree head allows the goniometer to measure range of motion in any direction without repositioning the instrument, making it suitable for all standard joint measurements including flexion, extension, abduction, adduction, and rotation. The three ISOM-calibrated scales ensure the readings are compatible with internationally recognized documentation standards used in physical therapy and rehabilitation.

Why is transparent plastic preferred for goniometers?
Transparent plastic allows the practitioner to see through the instrument to the joint being measured, making it easier to align the goniometer arms with the anatomical landmarks and axis of motion. This improves placement accuracy compared to opaque instruments, particularly for smaller joints or complex measurement positions.

What is the difference between this goniometer and the Baseline Absolute+Axis model?
This standard 360-degree goniometer relies on the practitioner's visual alignment with anatomical landmarks and gravity. The Baseline Absolute+Axis (AA) model adds integral bubble levels to establish a true vertical or horizontal reference, reducing inter-rater variability for measurements where reference plane alignment is critical. The standard model is appropriate for most routine assessments; the AA model is recommended when maximum measurement consistency across practitioners is required.

How do I clean the goniometer?
Wipe down with a damp cloth and mild disinfectant between patient uses, following your facility's infection control protocols. Avoid submerging the instrument or using harsh solvents that may cloud or damage the transparent plastic. Store flat or in a protective case to prevent warping of the arms.
