PositioningPosition involves four factors: the patient, the joint, the goniometer, and yourself. Incorrectly positioning any of these items can result in an inaccurate measurement of joint motion. You should position the patient so the joint to be measured can move through its ROM freely, without obstruction, and so you can easily observe the joint. The patient should be comfortable. If you need to measure several motions, you should plan the sequence of measurements so you will minimally change the patient's position. For example, you should measure all motions with the patient in prone before moving the patient to another position.
Finally, your position is just as important as the other factors in ROM measurements. Once you have placed the goniometer and ensured proper alignment, you must read the goniometer at eye level for an accurate reading. For example, if you measure hip flexion and read the goniometer in an erect standing position, the results could differ by several degrees from the reading you would obtain if you knelt down to read the goniometer at eye level.
Patient Stabilization and SubstitutionStabilization is isolating the motion of the joint while eliminating unwanted motion from adjacent structures. You must stabilize the patient before measuring ROM or examining end feel to assure reliable results. Most often, you will stabilize the proximal joint segment and move the distal segment. You must isolate a joint motion to examine it accurately. If you allow both joint segments to move, true joint end feel may be inaccurate.
Measurement TechniqueGoniometric measurement requires proper alignment of the stationary and moveable arms and the goniometer's axis (figure 6.5). Use bony landmarks to properly place these elements. Place the stationary arm along the longitudinal axis of the stabilized joint segment and the moveable arm parallel to the longitudinal axis of the moving joint segment. When using a 180°-scale goniometer, you may need to reverse the stationary and moving arms before the moveable arm will register on the scale. Align the goniometer's axis with the joint's axis of motion. If the goniometer arms are accurately placed, the fulcrum will be positioned correctly.

What is the purpose of using goniometer to measure ROM?In MSI prevention, a goniometer is used to measure range-of-motion (in degrees) of joints for either active or passive joint range. This is pertinent to functional reach and workplace design. Using a goniometer, an ergonomist can quantify posture, including measuring joint angles during performance of a task.
What is a goniometer used for quizlet?The universal goniometer is the most commonly used instrument to measure joint motion.
Which tool used for measuring flexibility of joint?Thus, measuring flexibility can simply be viewed as measuring the angle of joints or their range of motion (ROM). The devices used for the assessments are called goniometers.
What does a goniometer measure quizlet?goniometry. measuring the available range of motion or the position of a joint, typically in a passive motion and measured at one direction at a time with bilateral comparison.
