This prospective, multi-center, open-label, single-arm clinical study will evaluate the efficacy and performance of the BTL-043 and BTL-785F devices for alleviating TMJ pain. Up to 60 subjects will undergo four treatment visits, administered 2-10 days apart, followed by 1-month and 3-month follow-up visits. During a single treatment session at each visit, subjects will receive consecutive treatment with both devices. At baseline, informed consent, eligibility assessment, Fitzpatrick phototype evaluation, TMD Disability Index, VAS, weight and height measurements, 2D mandibular ROM photographs, and mandibular/lateral ROM assessments will be completed. A urine pregnancy test will be performed prior to each treatment visit. After the final treatment, subjects will complete the TCQ, SSQ & QoL, TMD Disability Index, and VAS, and repeat all physical assessments. At both follow-up visits, subjects will complete the SSQ & QoL, TMD Disability Index, and VAS, and repeat the physical assessments. Safety will be evaluated through documentation and assessment of adverse events at each treatment and follow-up visit.
