What is an electrogoniometer?
An electrogoniometer is a piece of equipment used to measure a
joint angle during dynamic movement. In some cases, it will only
measure in one plane of motion, e.g. Flexion/extension of the knee.
However, some may measure a certain movement in different planes
simultaneously, such as plantarflexion/ dorsiflexion (pointing the
toes down then up again), as well as abduction/adduction of the
ankle (side to side movement).
