Goniometer
Pronunciation: go-nee-AH-meh-ter
Instrument used to measure joint angles and range of motion in degrees.
Full Definition
A goniometer is a specialized measuring instrument consisting of two arms connected by a protractor-like axis, used to quantify joint range of motion in degrees. Standard goniometers have 180 or 360-degree scales, while digital versions provide more precise measurements. Proper goniometric technique requires specific anatomical landmarks for axis and arm placement. Measurements are essential for establishing baselines, tracking progress, and determining functional limitations in physical therapy practice.
Usage
Usage note: Specify type (universal, digital) and measurement plane when documenting.
