“…Physiological outcome measures are commonly studied in individuals with low back or cervical pain (47,48) and have been used effectively to discriminate healthy subjects from symptomatic patients with these conditions (49)(50)(51). Such outcomes may provide relevant information regarding the clinical TTS: Total tenderness score of masseter, temporalis, frontalis, sternocleidomastoids (SCM), trapezius, suboccipital muscles, coronoid and mastoid processes; mean muscles: mean of frontalis, masseter, temporalis, pterygoid, sternocleidomastoids, trapezius and neck muscle insertions; RCP: rectus capitis posterior; HA: headache; CSA: cross sectional area; ROM: range of motion; PPT: pressure pain threshold.…”
