- The patient sits on an examination table and the examiner holds the patient’s foot with the knee fully extended (as straight as possible).
- The examiner drops the leg, and a computer records the motion and vibration.
Typical equipment used is either electro-goniometers, uni-planar video or 3D motion analysis systems.
Using computer data for number of oscillations and amplitude, values of the Relaxation index (R1 and R2) are calculated and compared to norms.
