Buy Goniometer | Range of Motion Measurement Tools

A Goniometer is a measuring device that helps measure the range of motion at a joint. It is measured in degrees and seems like a protractor with two arms. One arm remains stationary, and the other is movable, which helps determine the degree or range of motion. Using this measuring device helps determine the cause and severity of issues you may have with joint movement. Health Products For You brings you a wide range of goniometric measurement tools from the best manufacturers like Fabrication Enterprises, Patterson Medical, North Coast Medical, and more.

What is a Goniomter used for?

Goniometry is a method that is used to measure angles. Goniometers are used in many fields, including medicine and physical therapy. Occupational therapy is also a great use for this measuring device. These devices are used to measure the range of motion of joints and come in various sizes to measure the range of motion of fingers to larger joints. These are made up of plastic and are marked with angle measurements. To be more specific, they can be used to measure

• ROM of the knee
• ROM of the arm at the elbow
• ROM of the waist
• ROM in the fingers and the wrist.

It is used to note the angle of motion at the start of treatment. As the treatment progresses, the range of motion is measured several times to track the effectiveness of the treatment.

Parts of a Goniometer

There are three parts of a goniometer:

1. Body: There is a circular part that can be measured as 180 degrees or 360 degrees.
2. Stationary Arm: This arm is attached to the circular part of the scale and is dependent on the goniometer's movement.
3. Movable Arm: The other arm is movable and is usually fixed with a screw on the goniometer

 

How to take Goniometric Measurements?

STEP 1

A goniometer has two arms. One arm has a circle with angle degrees marked on it, and the other is movable and helps in taking measurements. You keep the moving arm on the limb and see the angle degree to which the moving arm is pointing.

 

STEP 2

Place the center of the goniometer on the fulcrum or the center part of the joint. Keeping the center of the scale in the center of the joint would help you get an accurate measurement.

 

STEP 3

Hold the scale's fulcrum with a stationary arm on the limb. Keep the limb stationary while another limb rotates. This measurement can be taken for different body parts by aligning the arms of the goniometer with the bones in your body.

 

STEP 4:

Move the joint forward or backward as much as possible while holding the goniometer and stationary limb in place. Avoid moving any other part of your body except the limb being measured. Stretch the joint as far as it will go safely, then secure your limb.

 

STEP 5:

After stretching your limb as far as it can go, place the moving arm in the position where it gets aligned with the stretched limb.
Note:

• The scale's moving arm should go straight down the center of the limb that is moved.
• The fulcrum of the goniometer should still be placed on the center of the joint.

 

STEP 6:

The moving arm will point at the angle degree on the stationary arm, and you will get the degree and the range of motion. Note the range of motion in degrees on a piece of paper.

 

Techniques of Goniometry

• It is necessary to use a single notation system in goniometry. The 0 to 180-degree system is the most widely used method.
• The same measuring device should always be used to reduce the chances of instrumental error.
• The part of the body should be reasonably exposed and free to be measured using a goniometer.
• It is important to measure and record both the active and passive range of motion.

FAQs About Goniometric Measurements

1. How to read a Goniometer?

   The moving arm of the scale should be pointing at the angle degree on the stationary arm, telling you the range of motion. From there, you will get the degree of range of motion.

2. What is the normal ROM for a knee?

   A fully bent knee will max out at about 135° degrees of flexion, which is the full range of motion. As a general rule, knee flexion of about 125° will allow you to carry out most normal activities. For daily living, a minimum flexion of around 105°-110° is required.

3. How do you measure range of motion of all joints?

   A joint's ROM is usually measured by the number of degrees from the starting position of a segment to its position at the end of its full range of movement. The most common way this is done is by using a double-armed goniometer.

4. Does a goniometer measure flexibility?

   It is a device that measures an angle or permits the rotation of an object to a definite position. It is a useful tool for measuring the flexibility of a joint and is commonly used by physiotherapists, physicians, physical therapists, physiologists, athletic trainers, chiropractors, and sports scientists.
