A goniometer is a medical tool that is used to measure range of
motion. This range is expressed as angles and listed in
degrees.
Slide 3
Like a compass, the circular portion of a goniometer is marked
with degrees, from 0 to 360.
Slide 4
Slide 5
Two arms extend from this circle, one of which can pivot
freely. The arm that does not pivot is mounted at the zero-degree
point.
Slide 6
Slide 7
The axis (fulcrum) of the goniometer will be placed over the
joint. The moving arm follows the motion. Neutral extension at each
joint is recorded as 0 degrees. As the joint flexes, motion
progresses towards 180 degrees.
Slide 8
Slide 9
Look at the pictures on the Student Resource Sheet. Using what
you have learned about movement at a joint, match the action with
the correct range of motion picture. Each pair of pictures shows
the placement of the goniometer at the beginning and end of the
motion. Remember, you are measuring the range how far the limb
progresses at the joint while performing a specific motion.

NOTE: Three actions do NOT have a corresponding photograph.
Later, you will be responsible for describing, drawing, or
photographing the missing measurements.
