Best 7 Using a Goniometer to Measure Range of Motion of a Joint 2022

A goniometer is an instrument that measures the available range of motion at a joint. The art and science of measuring the joint ranges in each plane of the joint are called goniometry. To measure the range of motion physical therapists most commonly use a goniometer. A goniometer is an instrument that either measures an angle or allows an object to be rotated to a precise angular position. The term goniometry derives from two Greek words, γωνία ‘angle’ and μέτρον ‘measure’. The first known description of a goniometer, based on the astrolabe, was by Gemma Frisius in 1538.

A goniometer is an instrument that measures an angle or allows an object to rotate to a precise angular position. It has a graduated circle of 180° or 360º; it has a built-in rotating surface on its axis of symmetry so that it can measure any angular value.

The rotating surface has a built-in vernier to measure angles accurately.

The term goniometry is derived from two Greek words.

  • gōnia, meaning angle.
  • Metron, a measure of meaning.

This instrument for measuring angles is mainly used in the study of crystals. Nicolaus Steno, in 1669 determined the interfacial angles of quartz crystals by cutting sections perpendicular to the edges, the plane angles of the areas being the angles between the faces that were perpendicular to the cells.

The first instrument used to measure these angles was the contact goniometer devised by Arnould Carrangeot in 1780.

Physiotherapy goniometer

A goniometer is an instrument used to measure angles. Health professionals use goniometers to estimate the range of motion in the body.

What is a Physiotherapy Goniometer?

The goniometer comes from the Greek words “,, “angle and ” metron, ” meaning measure. A goniometer is an instrument used to measure angles. Health professionals use a goniometer to estimate the range of motion in the body. Different types include finger goniometers, bubble goniometers, gravity goniometers, and recording electrogoniometers. They are usually made of plastic but can be made of metal.

A goniometer can measure an active and passive range of motion. IT can be helpful for work trials, workspace design, and other health assessments. It is often used to measure a range of motion before a treatment program and again after the program is complete to analyze the improvement achieved.

The traditional physiotherapy goniometer can be used to measure flexion, extension, abduction, adduction, and rotation at the shoulder, elbow, wrist, hip, knee, and ankle.

 It is made up of a circular body similar to a protractor with a scale of 0 to 180 or 0 to 360 degrees and two arms. The center of the body is placed over the joint being measured, and the arms are moved until they line up with the bones that articulate at that joint.

How Physiotherapy Goniometers Work When Using It

A goniometer consists of two members. Usually, plastic or wood is connected by a joint and attached to a circular piece of the same material labeled with multiple angular measurements. When one limb is moved to or from the other, it drags along the circular part and displays a measure. Goniometers are made from various materials and vary drastically in size, depending on the nature of the application.

Applications

Medical professionals use goniometers to measure the range of motion found in a patient’s appendix before and after treatment to determine if the treatment improves the patient’s condition. Goniometers are used for an artist to draw a perfectly round straight line or circle. Furthermore, goniometers measure the angle of each face in a crystal structure and have led to more excellent knowledge about the atomic structure.

Advantages

Goniometers are portable and simple enough to be mass-produced in a short period. They are inexpensive and serve many different purposes, from those found in the medical industry to applications in the physical sciences. Goniometers have been in use for over two hundred years and have helped advance many fields.

Disadvantages

Goniometers must be carefully labeled concerning the angles they measure. Goniometers are limited in the materials they can be constructed from and must be used in conjunction with a surface medium to provide meaningful results.

Use of physiotherapy goniometer

  • Place the goniometer over the fulcrum of the joint. It will vary depending on the common you are measuring. Place the stationary arm of the goniometer along the fixed line of the body and the movable arm on the movable part of the body.
  • Ask your patient to move the joint in the desired direction. Have the patient move to her full range of motion, following the movement with the moving arm of the goniometer. Make sure the stationary component remains straight.
  • Stabilize the stationary portion of the body. IT is the part of the body that is proximal (closest to the body’s midline) of the joint you are testing. The patient mustn’t move her body while he moves the joint; this step isolates the movement of the joint for a more accurate measurement.
  • Observe the reading on the goniometer before removing it from the patient’s body. Be sure to take an accurate reading of the degree of movement on the goniometer and consistently use the same fixed and moving reference points on the body when measuring to ensure consistency. Be sure to record the range of motion of the joint.

Goniometer Structure

A goniometer consists of two metal rulers pivoted together at the centre of a graduated semicircle. The instrument is placed with its plane perpendicular to an edge between two faces of the crystal to be measured, and the rulers come into contact with the faces.

The angle between the rulers, as read off the graduated semicircle, gives the angle between the two faces. The rulers have slots to be shortened and their tips applied to a crystal partially embedded in its matrix. The illustrated instrument is used to rough measure crystals and prisms with multiple large angles.

Simple goniometer

It is a simple but powerful tool, but the significant limitation of the simple goniometer is that it only makes measurements up to 180º with a resolution of 1º. Still, it effectively complies with the specific measures for its design.

Universal Goniometer

This goniometer is specially designed to measure angles in the industry world, incredibly complex angles that a simple goniometer could not achieve; without a doubt, its measurement in verniers will help you in an efficient measurement.

Digital Goniometer

Recently, due to the advancement of technology, digital goniometers have been created that are somehow more precise than universal ones, providing you with exact measurements of any object that you are going to measure its angles.

Other Type of Goniometers

  • Audio goniometers:  In sound production, a signal contains stereo or mono qualities related to the sources of the sound. Sound and recording engineers use audio goniometers to measure the amount of stereo sound present in a given signal.
  • Communications Goniometers: Communications goniometers locate the communication data’s direction. Because of this, the military and various intelligence agencies primarily use goniometers for communications.
  • Crystallographic goniometers: Crystallographic goniometers measure the angle between the different surfaces of the crystal. This information has several uses to identify types of rocks and minerals.
  • Therapeutic Goniometers:  Physical and occupational therapists use goniometers to measure patients’ range of motion during therapy sessions. It helps therapists to monitor and measure the progress of patients.
  • Scientific Angle Goniometers: Scientific angle goniometers measure surface tension and are most often used for Earth and physical sciences. Gonio’s reflections reckon how reflective a surface is.
  • Positioning Goniometer:  A positioning goniometer or goniometric stage is used to rotate an object in space at an exact angle about a fixed point on the mounting surface of the fixture or stage. It uses a screwdriver that can be rotated manually or with a motor.

History of the Goniometer

Use of the Goniometer

It is necessary to ensure that it is in perfect condition to avoid any problem at the time of measurement.

  • Take the goniometer with caution.
  • Look and move the goniometer to see that it works perfectly.
  • Determine the object to which the angle is to be measured.
  • After you have selected the object, carefully place the goniometer.
  • You should make sure that it has a proper slope and is adjusted with the sides of the object that you will measure.
  • Observe the graduation that the goniometer has.
  • After you have known the graduation of the goniometer, you have to identify a black line that coincides with the arm of the goniometer that has the tab.
  • Finally, you should proceed to take these readings.

Benefits of Using a Goniometer

There are objects with numerous shapes in the world, and a tool is needed for their respective measurement; this instrument is generally used in industries to provide an exact measure in their products or the manufacture of them.

Without the goniometer in action, it isn’t easy to provide exact data to create or join different objects.

What are the benefits of goniometer?

The goniometer quickly helps provide a static angle measurement. Within the context of physical therapy, these type of measurements are well suited to establishing a patient’s passive range of motion (PROM).

What is a goniometer used for in musculoskeletal assessment?

A standard goniometer is used to evaluate the passive range of motion of all joints of the shoulder girdle and upper limb. Deficits of joint motion from immobility result in contracture of the joint capsule, adhesions in the joints, and shortening of both muscle and tendons above the affected joints.

How accurate is a goniometer?

The digital inclinometer was the most accurate method of assessment (6° minimum significant difference). The long arm goniometer had a minimum significant difference of 10°, smartphone app 12° and both visual estimation and short arm goniometry were found to be equally inaccurate (14° minimum significant difference).

What is an Electrogoniometer?

The electrogoniometer is an electronic device that uses angle sensors, such as potentiometers, strain gauges and, more recently, accelerometers to record such measurements. … The potentiometer’s electrical resistance can be used to determine the angle between the joints.
