The measurement of joint motion is one of a number of evaluative procedures important in programs for rehabilitation of the physically handicapped. Effective rehabilitation planning requires consideration of all aspects of behavior, including the degree to which an individual can move, for this influences the degree to which he can function independently.

The following are some of the ways in which physicians and therapists utilize the evaluation of joint motion as part of a patient’s permanent record: (1) An accurate record of joint motion provides information which is necessary for determining the extent of disability. It is important for the...

1. Evaluation of the patient should be done in a room which is warm and well lighted. The measurement process and its purpose should be explained. During the evaluation you should be alert to signs of discomfort or fatigue. Requiring your subject to maintain a given position for a prolonged period will cause muscle fatigue which may result in decreased motion.

2. Expose the extremity to be measured using draping when appropriate.

3. Place the extremity in the proper testing position. For teaching purposes this manual has specified testing positions. Actually positions vary but should allow freedom of movement and...

1. In the classroom setting it is recommended that subjects being measured complete less than normal limits of motion. Doing this will produce a more realistic experience, more similar to measuring an extremity with actual joint limitation.

2. Study each illustration noting goniometer placement and the normal limits of motion.

3. Read the instructions for testing position and goniometer placement.

4. Place your subject in the proper testing position as described. Have him complete the range of motion he is capable of producing.

5. Place the goniometer as directed and carefully take a reading.

6.Enter the readings in the spaces...

TESTING POSITION: For flexion -supine; for extension -prone.

GONIOMETER PLACEMENT:

Fulcrum: Centered at the greater trochanter.

Arms: (1) Draw a line from the anterior superior iliac spine (ASIS) to the posterior superior iliac spine (PSIS). Drop a perpendicular line from this line through the greater trochanter. Place one arm of the goniometer on this perpendicular line. (2) Parallel to the longitudinal axis of the femur.

Note: Positioning for hip extension is not illustrated. For extension the subject is placed in a prone position. Normal limits for extension are provided in the illustrations below. (See the next page for...
