The key to effective use of the clinical goniometer is understanding how it works. It is analogous to a magnetic compass, the needle of which always points north.
The rotating dial of the compass is turned so that it lines up with the needle. Bearings are then taken by pointing the compass at distant objects and reading the angle to which the needle is pointing.

MIE Clinical Goniometer
Don't be fooled by inferior imitations

The clinical goniometer uses gravity as its reference rather than magnetic north and consequently is used vertically, whereas the compass is used horizontally. Instead of a needle there is a semi-circular column of coloured fluid, the two ends of which are always level with each other. The dial is turned so that the arrow points to meniscus at the top of the fluid column.

Angles relative to the horizontal can now be measured by reading the dial where the meniscus crosses it. This is true irrespective of the shape of the subject, or where on the limb the goniometer is placed.

General Instructions

Maximum accuracy is obtained by always:

  • Holding the goniometer so that the dial is vertical.
  • Reading the dial from the bottom of the meniscus of the left side of the fluid column.
  • Allowing a short while for the fluid to settle before taking a reading.
  • Ensuring the goniometer does not move with respect to the limb which is being tested..

1. To set to true zero

  • Stand the goniometer on its side or end, on a flat, horizontal surface.
  • Rotate dial until the arrow is pointing to the bottom of the meniscus.
  • The goniometer is now calibrated for reading the true angle of the horizontal or vertical.

2. To set relative zero

  • With the joint in the neutral position, place the goniometer on the measurement site.
  • Rotate dial until the arrow is pointing to the bottom of the meniscus.
  • The goniometer is now calibrated for measuring the range of motion of the chosen joint.

3. Method for reading measured angle

  • With the limb in the desired position read
    the angle at the meniscus.
  • Use the outer scale for anti-clockwise movements.
  • Use the inner scale for clockwise movements.
