An interventional study of ultrasound and virtual reality in Temporomandibular Disorders (TMD), sponsored by Amany Refaat Mohamed Abdel Wahid. Completed at 1 site in Egypt. Open to participants aged 40 Years to 60 Years. Per ClinicalTrials.gov, last updated 2026-11-04.

The Purpose of the study is to compare between the therapeutic efficacy of ultrasound and virtual reality in decreasing pain and improving range of motion (ROM) for patients with temporomandibular joint disorder after tooth extraction surgery.
The study will be carried out on patients suffering from temporomandibular joint disorder following tooth extraction surgery. Their ages will range from (40-60) years. They will be randomly divided into two equal groups:
Group A:
This group will include 25 patients suffering from Timbro Mandibular Joint (TMJ) dysfunction (pain and reduced mouth opening) after tooth extraction. They will receive pulsed ultrasound and traditional manual therapy. The first session of treatment will be 24hr after extraction for three times for one week.

591 studies on the registry are indexed under Temporomandibular Joint Disorders; 149 are open to participants now.
This study's enrollment of 60 is above the median of 45 across 415 interventional studies indexed under Temporomandibular Joint Disorders.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
The subject selection will be according to the following criteria:
Exclusion Criteria:
. Surgery that conducted on the temporomandibular joint (meniscectomy, arthroscopy, etc.).
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.
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.

pain free maximum mouth opening (MMO)
Measured using a millimeter ruler as the maximum interincisal distance (in millimeters) achieved without pain. Participants are instructed to open their mouth as wide as possible without experiencing pain, and the distance between the incisal edges of the upper and lower central incisors is recorded. Scale title: Pain-Free Maximum Mouth Opening (MMO) measured with a millimeter ruler Minimum value: 0 mm Maximum value: No fixed upper limit (typically reported as the measured distance in millimeters) Interpretation: Higher values indicate better mandibular mobility and improved mouth opening.
Time frame: before and after the treatment (after 1 week)
pain measurement
Visual Analog Scale (VAS) for Pain: Pain intensity is assessed using a 10-cm Visual Analog Scale, where participants indicate their pain level by marking a point on a horizontal line anchored by "No Pain" at one end and "Worst Imaginable Pain" at the other. Scores range from 0 to 10 cm, with higher scores indicating greater pain intensity and worse outcomes. Scale title: Visual Analog Scale (VAS) for Pain Minimum value: 0 cm (No Pain) Maximum value: 10 cm (Worst Imaginable Pain) Interpretation: Higher scores indicate worse pain (greater pain intensity).
Time frame: before and after the treatment ( 1 week)

Ran from May 2026 to primary completion in Jul 2026, 1 month.
Of 242 non-industry interventional studies with no phase under Temporomandibular Joint Disorders, half reached primary completion within 11 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 21. This study's 1 month is below that.
Counting every sponsor, half of 246 studies reached it within 10 months; a quarter within 5 and three quarters within 21.
