Maitland Mobilization Versus Therapeutic Ultrasound on Trismus Following Third Molar Surgery
Sponsor: Cairo University
Summary
This study aims to compare the effect of Maitland mobilization and therapeutic ultrasound on trismus (limited mouth opening) following third molar (wisdom tooth) surgery. Participants who experience limited mouth opening after third molar surgery will receive one of two treatment methods: Maitland joint mobilization or therapeutic ultrasound. These treatments are commonly used in physical therapy to improve jaw movement and reduce stiffness. The purpose of this study is to determine which treatment is more effective in improving mouth opening and reducing symptoms after surgery. Participation is voluntary, and all collected information will be kept confidential and used only for research purposes.

Interventions
Maitland Joint Mobilization
Maitland mobilization was applied to the temporomandibular joint using graded passive accessory and physiological joint mobilization techniques (Grade I-IV depending on patient tolerance). The technique was performed by a trained physical therapist to improve joint mobility and reduce trismus following third molar surgery. Treatment sessions were conducted three times per week for four weeks
Therapeutic Ultrasound group
using an ultrasound device , such as the Chattanooga Intelect Mobile 2, which operates at a 1 MHz frequency to target deep tissues like the temporomandibular joint (TMJ) and surrounding muscles. The therapy was conducted three times a week for four weeks, with each session lasting 10-15 minutes. A water-based conductive gel was applied to the skin to facilitate effective transmission of sound waves, and the intensity of the ultrasound was adjusted between 0.8 to 1.5 W/cm² based on patient tolerance. The transducer was moved in slow, circular motions over the TMJ and affected muscles, focusing on areas of pain or stiffness (Bhushan et al., 2025).
