Baseline Goniometer, 8 Inch, 360 Degree, Plastic

The Baseline 8-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. The 8-inch arm length is well-suited for mid-size joint assessments including the elbow, wrist, knee, and ankle.

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 of mid-size joints including the elbow, wrist, knee, and ankle. It is well-suited for clinical settings where multiple practitioners share instruments and need a clearly readable, standardized tool that produces consistent results. The 8-inch arm length strikes a practical balance between the compact 6-inch model and the full 12-inch clinical goniometer, making it versatile across a range of joint sizes. Anyone seeking a durable, affordable, full-featured plastic goniometer for daily clinical use at mid-size joints will find the Baseline 8-inch model a dependable and practical choice.

Frequently Asked Questions

How does the 8-inch model compare to the 6-inch and 12-inch versions?
The 6-inch model is most compact and best suited for smaller joints such as the fingers and wrist. The 8-inch model is versatile for mid-size joints including the elbow, wrist, knee, and ankle. The 12-inch model provides the longest arms for large joint measurements such as the hip and shoulder, where greater arm length improves alignment accuracy. Choose the size that best matches the joints you assess most frequently.

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 anatomical landmarks and the axis of motion. This improves placement accuracy compared to opaque instruments, particularly for complex measurement positions.

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 over time.
