Hands-On therapy or ultrasound: which works better for locked jaw after wisdom tooth surgery?
NCT ID NCT07575100
First seen Jun 25, 2026 · Last updated Jul 21, 2026 · Updated 3 times
Summary
This study tested two physical therapy treatments—Maitland joint mobilization (a hands-on technique) and therapeutic ultrasound—to help people with limited mouth opening after wisdom tooth removal. Sixty adults aged 20 to 30 who had jaw stiffness within 2 to 14 days after surgery received one of the treatments three times a week for four weeks. The goal was to see which method better improves jaw movement and reduces pain.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Maitland joint mobilization (a hands-on physical therapy technique) and therapeutic ultrasound (a device that uses sound waves)
- What this could lead to
- If successful, this could point to a more effective physical therapy approach for easing jaw stiffness after wisdom tooth surgery.
- What could go wrong
- This is a small, completed study with only 60 participants, so results may not apply to everyone. Both treatments are generally low-risk, but individual responses vary.
