Range of motion is the amount of movement in any given joint. The wrist and elbow joint are involved in supination of the arm. Normal range for supination is 80 to 90 degrees, although this can vary from person to person based on bony structure and mobility, as well as soft tissue tension. Injury restrictions, such as pain and swelling, can also be limiting factors. Full or normal range of motion is important to maintain activities of daily living. Accurate assessment can be difficult to obtain without training and practice, but a measurement for general purposes can be attained.
Range of Motion
Step 1
Bend the elbow to the position of 90 degrees and hold it closely to the side to eliminate shoulder involvement.
Step 2
Hold a pencil in the hand, with the thumb and pencil pointing toward the ceiling.
Step 3
Rotate the wrist outward until full range of motion is achieved. This should bring the pencil parallel with the floor.
Measurement
Step 1
Place the two arms of the goniometer parallel with the pencil in the starting position so that they are pointed up toward the ceiling.
Step 2
Maintaining the position of the stationary arm, rotate the moving arm along the same axis as the pencil.
Step 3
Record the number on the goniometer at the end of the range of motion. This should be between 80 to 90 degrees for a normal reading.
Tips and Warnings
- Comparison of the motion of both wrists should be done to get an idea of the individual's normal range.
- Never force motion through pain unless directed and supervised by a medical professional.
