I'm going to have some testing done to see if I can go back to work. I'm worried that I don't have enough motion for the job I do. Will the therapist really be able to tell?

Therapists use a tool or device called an inclinometer for these types of measurements. The idea is designed after the inclinometers used by engineers to measure angles of slope (or tilt) and elevation or inclination of an object.

A hand-held device that looks like a round clock is positioned along the spine. A needle shows the amount of spinal movement that occurs as you bend forward, backwards, or sideways. Any deviation from the true vertical or horizontal is measured in one-degree units of movement.

Readings are fast and accurate so you don't have to stay in any one position too long. Some models of the inclinometer are held by the therapist. Others are strapped on with a velcro belt.

The therapist may also measure your hip and lower back flexibility using an adjustable Sit and Reach Flexibility Tester. You sit with your legs straight out and your feet against the device. Then you bend forward. Using your hands, you push a slide bar forward as you bend forward. The slide bar has units of measurement to show how far you can go.

The results from these tests will be compared with the movements needed and amount of motion required for your job. Therapists use other tests as well to make sure workers are ready and safe to return to work.
