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.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
