Patient traction. Left: Patient initiated left sided head/neck traction in seated
position, her left shoulder is braced against secure support, the head is pulled by
pulley system; Right: Patient graduated to more aggressive traction; the natural body
weight is forcing head and neck to the left, leveraged on firm block, the rest of the
body is supported in a neutral position.

The patient's traction involved a left-sided translation and tilt in a seated position, where padding was used to relieve traction pressure from the jaw (Fig. 2). As the patient better tolerated this procedure, she was graduated to a right side-laying position where the head and neck was leveraged against an angled block, again stretching the head and neck into the mirror image, or to the left (Fig. 2).
TMJ vibration analysis. Left: Abnormal vibration characteristics representative of
TMJD; Right: Normal vibration characteristics after treatment.

The patient's dentist performed a TM joint vibration analysis (JVA) and determined the affected right joint to have a vibration signature consistent with TMJD characteristics (Fig. 3).
