Activity 4.1.2: Range of Motion Yellow highlight goes in Lab Journal , Blue goes in Portfolio Introduction You come home from school, run up the stairs and throw your backpack on your bed. This sequence of events took only minutes, but used joints in your ankles, knees, elbows, shoulders, and wrists. You realize that when you threw your bag, your cell phone slid under your dresser. You try to reach it, but you cannot seem to get your arm back far enough. Your twin sister comes in and offers to help. She bends down, stretches and twists her arm and almost instantly, you have your phone back. If we all have the same general arrangement of bones and joints, why was she able to reach the phone with ease when you did not even come close? Range of motion (ROM) studies assess joint motion and provide a measure of overall flexibility. You may have heard of This does people who are “double-jointed.” not mean that they have twice as many joints as you do; rather, the ones they do have are unusually flexible. We often use the everyday terms such as bend and flex to describe the motion of our limbs, but scientists and doctors use specific terms to describe just how a set of bones move at a joint. These precise terms describe the direction of motion as well as the relationship of one body part to another. As you will see in the next lesson, muscles are often named using terminology that is linked to the type of motion they permit. In this activity, you will use a device called a goniometer to measure the angles resulting from the movement of various joints in the body. With your team, you will match body actions with range of motion photographs. You will use information from the pictures to measure your own range of motion and to devise a strategy for measuring range of motion of body movements not shown in the photographs. These measurements can be compared from person to person and can be used to rate overall flexibility and range of motion.
