Human Body Systems Activity 4.1.2 Range of Motion – Page 1
Procedure 1. With a group of three, research the following pairs of terms that describe possible movement at a joint. Use the Internet or reference textbooks to guide your search. o Depression and elevation o Rotation and circumduction o Flexion and extension (and hyperextension) o Abduction and adduction o Plantar flexion and dorsiflexion 2. In your laboratory journal or on a body system graphic organizer, create a visual that helps you remember the path of motion for each pair of terms. Also describe each motion in words. 3. Obtain a goniometer and a Student Resource Sheet from your teacher. A goniometer, like a protractor, allows you to measure angles. In this case, you will be measuring the range of motion of your joints. One arm of the goniometer will remain stationary, while the other arm will move to measure the angle of your limbs. Your teacher will demonstrate proper use of the goniometer. 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. In the picture below, the moving arm has progressed approximately 50 degrees. 4. 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 © 2014 Project Lead The Way, Inc. Human Body Systems Activity 4.1.2 Range of Motion – Page 2
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. 5. When you think you have all of the pictures matched with the correct action, check your answers with your teacher. 6. Let your teacher know if you are experiencing any pain in your joints or if you are limited in mobility in any way. Help others in your group complete measurements, but do not complete experiments that could cause you pain or injury.
