Study summary

This study will use a between-person design. Participants will be treatment-seeking patients with chronic masticatory muscle pain. Participants who are eligible for the study and consent to participate will be randomly assigned to receive a brief behavioral intervention for chronic orofacial pain called Physical Self-Regulation or a control intervention. Interventions will be administered via telehealth in both arms. Both interventions will consist of 2 50-minute sessions scheduled approximately two weeks apart. Participants will be contacted two weeks and three months after completing the interventions to provide additional follow-up data. Investigators hypothesize that both PSR-TH and the control intervention will demonstrate strong feasibility (i.e., recruitment of at least 1 participant per week, >75% retention, >95% interventionist fidelity, and adequate acceptability, credibility, and burden). Investigators also hypothesize that specific biopsychosocial variables will moderate PSR-TH-related changes in outcomes, and that PSR-TH-related changes in perceived control over pain, self-efficacy, coping, parafunctional habits, and relaxation will mediate treatment effects.

Read the detailed description

Chronic masticatory muscle pain disorders (MMPD) consist of several conditions (e.g., myofascial pain, local myalgia) characterized by pain in the muscles of the temporomandibular area lasting longer than three months. MMPD affects 5-12% of adults, is the most common cause of chronic non-odontogenic facial pain, and the second most common musculoskeletal pain condition after chronic low back pain. MMPD is associated with pain-related interference with daily activities, diminished quality of life (QoL) and costs of > $4 billion/year in the US, representing a serious public health issue. Chronic MMPD is most effectively managed with multidisciplinary treatment. One brief psychological intervention that has been particularly promising for improving orofacial pain outcomes and QoL in MMPD is physical self-regulation (PSR). Relative to standard dental care (SDC) alone, those who received SDC+PSR experienced reduced pain intensity up to 6.5 months later (Cohen's D = 0.67). These data suggest that PSR may be a promising intervention for improving pain outcomes in MMPD. Despite the promise of PSR, one of its major shortcomings is that treatment utilization is low, with less than 50% of eligible patients beginning PSR when offered in person. Offering PSR via telehealth may be a solution. Telehealth interventions improve access to care and are preferred by patients over in-person interventions. Preliminary data of treatment utilization for PSR-TH are promising, with over 80% of eligible patients beginning the intervention when offered via telehealth. However, it is not known if PSR-TH is efficacious above and beyond nonspecific treatment effects (e.g., people having more contact with a therapist, people inadvertently modifying their behavior to please their therapist, natural regression to the mean of pain symptoms, etc.). The efficacy of PSR-TH to treat MMPD needs to be formally tested; however, additional data regarding feasibility and moderating/mediating factors of PSRTH are needed to support such a trial. First, PSR-TH and a control intervention need to be formally piloted in patients with MMPD to 1) determine how willing patients are to participate in research (i.e., recruitment), 2) determine the completion rates for both interventions (i.e., retention), 3) quantify how well interventionists are able to deliver the interventions in a standardized way (i.e., fidelity), and 4) establish patients' perceived acceptability, credibility, and burden of both interventions. Second, a body of work has examined biopsychosocial moderators and mediators of responses to psychological interventions (e.g., cognitive behavioral therapy, [CBT]) in MMPD, but never of PSR-TH specifically. Identifying relevant moderators and mediators in this project will allow for more thorough assessment of those specific relationships in a future Phase II trial, advancing understanding of how PSR-TH works, and for whom. To accomplish these aims, treatment-seeking patients with chronic MMPD will be randomly assigned to two 50-min telehealth sessions of PSR or a control intervention (N=52/group) and will provide biopsychosocial moderator, mediator, and outcome data at baseline, after each intervention sessions, two weeks following the intervention, and three months following the intervention. The investigators hypothesize that both PSR-TH and the control intervention will demonstrate strong feasibility (i.e., recruitment of at least 1 participant per week, >75% retention, >95% interventionist fidelity, and adequate acceptability, credibility, and burden). The investigators also hypothesize that specific biopsychosocial variables will moderate PSR-TH-related changes in outcomes, and that PSR-TH-related changes in perceived control over pain, self-efficacy, coping, parafunctional habits, and relaxation will mediate treatment effects.

Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

What researchers measure

Primary outcomes

  1. Change in pain intensity

    Pain intensity will be measured with the Graded Chronic Pain Scale Pain Intensity Subscale. Participants rate their worst pain, least pain, average pain, in the last 24 hours and pain right now using an 11 point Likert scale ranging from 0 to 10 with higher scores equating to greater pain. Scores are averaged for the total pain intensity score.

    Time frame: Baseline (week 0), post intervention (week 5) and 3-month follow-up (week 15)

  2. Change in pain interference

    Pain interference will be measured with the The Graded Chronic Pain Scale Pain Interference Subscale. Participants rate how much the pain has interfered with 7 daily activities on an 11 point Likert scale ranging from 0 to 10 with higher scores equating to greater interference. Pain interference is scored as the mean of the 7 items.

    Time frame: Baseline (week 0), post intervention (week 5) and 3-month follow-up (week 15)

  3. Change in quality of life

    Quality of life will be measured with the Satisfaction with Life Scale. Likert scale with 7 items scores range from 7 to 35 with higher scores equating to better quality of life.

    Time frame: Baseline (week 0), post intervention (week 5) and 3-month follow-up (week 15)

  4. Recruitment rate

    Number of patients who are consented into the study per month

    Time frame: Baseline (week 0)

  5. Retention rate

    Number of consented patients who also complete the three-month follow-up assessment

    Time frame: Follow up Visit at Month 3 (week 15)

  6. Interventionist Fidelity Session 1

    Each intervention session will have a checklist of items that need to be covered by the interventionists. All study sessions will be audio-recorded. A subset of all audio recordings will be checked for interventionist fidelity, defined by the following percentage: Total items covered by interventionist/ Total possible items to be covered in that session

    Time frame: Study Visit 1 (week 1)

  7. Interventionist Fidelity Session 2

    Each intervention session will have a checklist of items that need to be covered by the interventionists. All study sessions will be audio-recorded. A subset of all audio recordings will be checked for interventionist fidelity, defined by the following percentage: Total items covered by interventionist/ Total possible items to be covered in that session

    Time frame: Study Visit 2 (week 3)

  8. Treatment Acceptability

    Treatment Acceptability and Adherence Scale. The scale will measure what participants overall evaluation of if treatment was fair, reasonable, and appropriate. 6 item Likert scale with scores on each item ranging from 1 to 9 with higher scores equating to greater acceptability. Acceptability is scored as the mean of the 6 items.

    Time frame: Study Visits 1 and 2 (up to 2 weeks)

  9. Treatment Credibility

    Treatment Credibility/Expectancy Scale will measure how feasible is it the intervention will work and work for the participant. 6 item Likert scale with scores on each item ranging from 1 to 9 with higher scores equating to greater credibility. Acceptability is scored as the mean of the 6 items.

    Time frame: Study Visits 1 and 2 (up to 2 weeks)

  10. Research Burden

    Research burden will be measured by administering 8 selected items from the Perceived Research Burden Assessment. Participants rate how burdensome the study was on an 8 item assessment on a 5 point Likert scale ranging from strongly disagree to strongly agree with higher scores equating to greater burden. Burden is scored as mean of the 8 items.

    Time frame: Follow up Visit at Month 3 (week 15)

Secondary outcomes

  1. Treatment Satisfaction

    Treatment Satisfaction Questionnaire 8 items on a 4 point Likert scale. Higher scores equate to greater satisfaction. Satisfaction is scored as mean of the 8 items.

    Time frame: 2-week follow-up (week 5)

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jun 17, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
