Sonoelastography assessed the elasticity index (EI) of the masseter and temporalis muscles, while microvascular imaging evaluated the velocity index (VI) of the masseter muscle. Pain\u2010free maximum mouth opening (PMMO), pain pressure thresholds (PPTs) of the masseter, temporalis, sternocleidomastoid, and trapezius muscles, as well as masseter and temporalis muscle thickness at rest and during clenching, were measured.
