Question

The 90 degrees position is regarded as the 0 degree position when using a goniometer to measure which joint angle?

a) Shoulder abduction
b) Elbow flexion
c) Knee flexion
d) Hip flexion

Answer 1

When using a goniometer, the 90 degrees position of an outstretched arm is regarded as the 0 degree position during shoulder abduction measurements.

Step-by-step explanation:

The 90 degrees position is regarded as the 0 degree position when using a goniometer to measure shoulder abduction. This means that when the arm is outstretched horizontally (at 90 degrees from the standing body), this position is considered the starting point, or 0 degrees, for measuring the range of motion for abduction. Any movement of the arm away from the body from this position is considered abduction and is measured from the baseline of 0 degrees afforded by the 90 degrees outstretched arm position.
