Baseball, basketball, football, hockey, soccer, gymnastics, jogging, rock climbing, hang gliding, parachuting and high-impact aerobics are activities that should be avoided.
What does the goniometer test measure?
A goniometer is a device that measures an angle or permits the rotation of an object to a definite position. In orthopedics, the former description applies more. The art and science of measuring the joint ranges in each plane of the joint are called goniometry.
How does goniometer measure range of motion?
Calculate joint range of motion by measuring the angles between the beginning position and the ending position of available motion. Goniometers similar to a carpenter level are called gravity-dependent goniometers, or inclinometers, and are used most often to measure motion in the spine.

What joints can you measure with a goniometer?
There are many joints you can measure using the goniometer, such as the knee, hip, shoulder, or wrist. It's important to align the center of the goniometer along the center of the joint, using the two arms to track how far a limb can bend or extend. Steps.
How to stretch a goniometer?
Stretch the joint through the range of motion. While holding the goniometer and stationary limb in place, move the joint as far forwards or backwards as possible. Be careful not to move any other part of your body except the limb that’s being measured. Stretch the joint as far as it will safely go, and then hold your limb in place.
How to hold a goniometer steady?
Hold the goniometer's stationary arm along the limb being measured. Once the center of the goniometer is on the joint, align the stationary arm (the arm attached to the circle) with the limb that’s going to remain in place. This is the limb that you’ll hold steady while the other limb rotates.
How to measure hip extension?
Flexion of the hip is the movement of one leg being brought upwards towards the body—measure this angle by placing the goniometer on the side of the hip and aligning the arms. To measure the extension, the person will lay on their stomach and move their leg backwards as far as possible.
How many arms does a goniometer have?
A goniometer has two arms: one that’s attached to the circle with the angle degrees on it, and a movable arm that does the measuring. Make sure you understand how the moving arm points to the angle degrees so that you’re able to measure the range of motion accurately.
What is a goniometer used for?
A goniometer is essentially a protractor with two arms extending from it, used to measure a joint's range of motion. They're most often used in physical therapy to track the progress of a joint's movement . There are many joints you can measure using the goniometer, such as the knee, hip, shoulder, or wrist.
Where should the center of a goniometer be placed?
The center of the goniometer, also called the fulcrum, should be placed right on the fulcrum of the joint you’re measuring. The center is the round section attached to the stationary arm.
Introduction
The knee joint's range of motion (ROM) is an important clinical parameter used in knee assessment. Knee flexion can be measured with a goniometer. The goniometer can simply measure the joint angles. It has some limitations not allowing the clinician to analyse the ROM and track the knee joint during eg walking or maximum squat.
Testing position
Patient is in prone with test-side ankle off plinth and leg in extension.
How to get a goniometer to read your knee?
Straighten your leg out so the back of your knee is against the floor. Start by checking to see if you can extend your knee. Straighten out your leg so the back of your knee is against the floor or as close as you can comfortably get it to the floor. Check the goniometer or phone app’s angle to see your reading.
What is the goniometer for knee extension?
If your knee is fully extended, the goniometer will be at 0 degrees.
How to measure knee flexion?
Measure the distance from your buttocks to your heel. Repeat for the other knee when you finish measuring the first knee’s flexion. Note that this will not give you an angle, but it can provide a starting point to help track your progress. For example, if you can get your heel within 3 in (7.6 cm) of your buttocks, then you likely have full knee flexion, which is 155 degrees.
How many degrees does a knee flex?
For example, the American Academy of Orthopedic Surgeons defines normal knee flexion as 141 degrees plus or minus 5.3 degrees, while the American Medical Association defines it as 150 degrees.
How to check if your knee is extended?
Slide your fingers under your knee to check the degree of its extension. Place your palm flat on the ground beside your knee and then try to slide your fingers under your knee starting with your index finger. Keep your knee pressed as flat against the ground as possible as you do this.
How to determine the angle of your knee?
Use the number of fingers you can fit under your knee to determine the approximate angle of your knee when it’s extended. The approximate angles are as follows: 2 fingers: 0 degrees. 4 fingers: 5 degrees. Whole hand: 10 degrees. Can’t get any fingers under your knee: -5 degrees or hyperextension. ...
Where to place a goniometer?
Position the stationary arm of the goniometer along your outer thigh so it’s in line with your greater trochanter, or the bone at the end of your femur that connects to your hip. Position the other arm of the goniometer with the lateral malleolus, which is the protrusion on the outside of your ankle.
How to measure knee range of motion?
The best way to measure knee range of motion is to: Lie down on your back with your leg straight, on a flat, preferably hard surface. Place the axis of the goniometer over the lateral femoral epicondyle. Line the stationary arm of the goniometer up with the greater trochanter along the outer thigh. Line the other arm of the goniometer up with ...
What is a goniometer?
A goniometer is essentially a specially designed protractor that measures joint angles. There is a circle in the middle of a goniometer representing 360 o of motion, out of which come two extending arms: a stationary arm (connected to the protractor) and a moveable arm.
What Is Normal Functional Knee ROM?
At the knee joint, most functional activities require up to 120 degrees of knee flexion, rather than the full 135 degrees, however, virtually all functional activities require full knee extension.
What is a normal ROM for a knee?
Normal passive knee ROM is: Passive Knee Flexion: up to 150 o, depending on the size of the leg – the limit is the calf pushing onto the back of the thigh. Passive Knee Extension: up to 10 o hyperextension is considered normal.
How to find the greater trochanter?
To find the greater trochanter, find the midpoint of the bony ridge on the top of your pelvis (the iliac crest) and bring your fingers down 15-20cm until you feel a bony lump. The greater trochanter is more towards the back of the thigh than the front due to the large muscle bulk of the quads on the front of the thigh. You will have to press in through the soft tissues of the thigh to feel it.
What is passive knee ROM?
Passive Knee ROM: How far the knee can bend and straighten when moved by an external force, usually another person – the leg and knee muscles completely relaxed.
What happens when your knee is limited?
When knee movement is limited, it causes pain, impairs function and makes us predisposed to knee injuries.
Where is the goniometer axis located?
In the Wrist Joint example, the goniometer axis is placed over the rotational axis of the joint ( where the bones of the hand meet the bones of the arm forming the wrist joint). As the hand moves, one goniometer arm is always kept aligned with the arm, and the other goniometer arm is allowed to move with the hand.
Can you print a goniometer on card stock?
If you have printed the goniometer template directly on card stock, just cut that out. If you printed on regular printer paper, find some stiffer material to which to affix the pattern. Here I show Card Stock, Paper Board (such as from a cereal box), and thin cardboard. I chose the paperboard because it was easy to cut, but has a good degree of stiffness.
Is a goniometer transparent?
Unlike the 'store-bought' kind, our goniometer is not transparent, so the notch will let you read the dial when taking an angle measurement.
Can you make a goniometer pattern on heavy cardstock?
If you make your copy directly on heavy weight card-stock, that's all you need. If you print or copy onto regular print paper, in the next step you will need to tape or glue your goniometer pattern onto some stiffer material.
