Goniometers are used to test and measure the flexibility of a joint. Small joint goniometers
are used for the fingers and toes while larger goniomters
are for measuring range of motion in large extremities like the arms, shoulders or legs. The Baseline Bubble Inclinometer
accurately measures complete range of motion. Plastic goniometers
are constructed with clear plastic permitting the observation of joint's axis of motion and range of motion.
