the measurement of angles created at human joints by the bones of the body.
an imaginary flat surface that divides the body into sections.
arc of motion that occurs at a joint or a series of joints.
Range of motion
a characteristic sensation perceived by the examiner when the end of joint range of motion is reached.
same subject, same conditions yield same results.
measures what it is purported to measure.
the study of the movement of bones associated with joints.
the study of movements between adjoining articular (joint) surfaces.
The patient is moving the joint through its available range. No outside assistance.
Active range of motion
The therapist is moving the joint through its available range. The patient is not helping with the movement.
Passive range of motion
soft tissue approximation
example: knee flexion (contact between soft tissue of posterior leg and posterior thigh).
example: hip flexion with the knee straight (passive elastic tension of hamstring muscles).
bone contacting bone
example: Elbow extension
(contact between the olecranon process of the ulna and the olecranon fossa of the humerus).
less than normal passive range of motion (PROM).
more than normal passive range of motion (PROM).
Explain and demonstrate the importance of testing procedures.
The examiner must have the knowledge and skill to properly perform the procedures in order to obtain an accurate measurement. A measurement that has good reliability aides in setting therapeutic interventions, and aides in clinical decision making process.
Explain the importance of testing positions.
Refers to the positions of the body that are recommended for obtaining goniometric measurements, helps to stabilize the subject's body and proximal joint segment.
Demonstrate the importance of testing positions.
Designed to do the following:
1. Place the joint in a starting position of 0 degrees.
2. Permit a complete ROM.
3. Provide stabilization for the proximal joint segment.
Explain and demonstrate the importance of stabilizations.
Isolating the motion to one joint helps to ensure that a true measurement of the motion is obtained, rather than a measurement of combined motions that occur at a series of joints.
Explain and demonstrate the importance of clinical estimates of range of motion.
Can be used when excessive soft tissue is covering the landmarks, and can be useful in the learning process. Examiner can compare ROM to values from similar people.
Although, not very accurate and yields only subjective info in contrast to the goniometer.
Explain and demonstrate the importance of palpating bony landmarks.
Ensures proper placement on the landmark and assures accuracy and consistency of the measurements.
Explain and demonstrate the importance of recording starting and ending positions.
To properly define the ROM it is important to include both starting and ending positions. Recordings with only the total ROM give no information as to where a motion begins and ends. This ensures that the measurement can be interpreted correctly.
Explain and demonstrate the steps to ensure reliability.
1. Use consistent, well-defined positions.
2. Use consistent, well-defined, and carefully palpated anatomical landmarks to align the goniometer.
3. Use the same amount of manual force to move subject's body part during successive measurements of passive ROM.
4. Urge subject to exert the same effort to move the body part during successive measurements of active ROM.
5. Use the same device to take successive measurements.
6. Use a goniometer that is suitable in size to the joint being measured.
7. If examiner is less experienced, record the mean of several measurements rather than a single measurement.
8. Have the same examiner, rather than a different examiner, take successive measurements.
