What to buy with Range of Motion Measurement Tools
How to take Goniometric Measurements?
- There are two arms in a goniometer. One arm has a circle with angle degrees marked on it, and the other arm is movable and helps in taking measurements. You will keep the moving arm on the limb and will see the angle degree that the moving arm is pointing to.
- Place the center of the goniometer on the fulcrum or the center part of the joint. Keeping the center of the scale on the center of the joint would help you to get an accurate measurement.
- 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.
- Move the joint forward or backward 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.
- 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.
- Adjusting Moving Arm of Goniometer with Moving Limb
- 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.
Sammons Preston EZ Read Jamar Goniometer FAQ
What is the normal ROM for a knee?
A fully bent knee will max out at about a full range of motion of 135° degrees of flexion. Generally, 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.
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 sport scientists.
How do you measure a 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.
How to read 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.
