Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study was designed to investigate the effectiveness of diadynamic current, one of the electrotherapy methods added to rehabilitation in the treatment of bruxism. Individuals over the age of 18 diagnosed with bruxism will be randomly assigned to one of the following groups using the sealed envelope method: rehabilitation program (control group) or rehabilitation program combined with diadynamic current (experimental group). The intervention will consist of an exercise program conducted jointly for the experimental and control groups. Participants will be given a structured exercise program to be performed in person 3 days a week for 6 weeks. In addition to the exercise program, the experimental group will receive diadynamic current treatment at each session. Pain intensity will be assessed using the Visual Analog Scale (VAS), pressure pain threshold with an algometer, muscle strength with a hand-held dynamometer, bite force with a pinch meter, maximal mouth opening with a caliper, and head posture with the craniovertebral angle. Oral habits will be evaluated using the Oral Behavior Checklist, and anxiety levels will be assessed with the State-Trait Anxiety Inventory (STAI).

Rehabilitation Program

Participants will be given a structured exercise program to be performed in person 3 days a week for 6 weeks.

Group Type ACTIVE_COMPARATOR

Exercise Program

Intervention Type OTHER

Participants will be given a structured exercise program to be performed in person 3 days a week for 6 weeks. The traditional program will include soft tissue relaxation exercises applied to the masseter and temporalis muscles following breathing exercises, controlled jaw opening and closing, jaw lateralization exercises, motor control targeting the temporomandibular joint and masticatory muscles, isometric strengthening, and stretching techniques. Additionally, exercises for the gradual stabilization of the cervical region and posture exercises will be added. The exercises will be performed three times a week under the supervision of a physical therapist.

Rehabilitation Program with Diadynamic Current

In addition to the rehabilitation program, participants will receive diadynamic current therapy during each session.

Group Type EXPERIMENTAL

Diadynamic current therapy applied in conjunction with exercise

Intervention Type OTHER

In addition to the exercise program, the experimental group will complete a total of 12 minutes of treatment per session using three different modes of diadynamic current therapy in sequence. Among the current parameters used, the diphase fixe and long-period modes will be applied at the sensory threshold level for four minutes each, while the courtes-period mode will be applied for four minutes at the motor threshold level, at an intensity that will cause short muscle contractions. The application will be performed on the anterior temporalis and masseter muscles, which are located in areas adjacent to the temporomandibular joint and contain painful or myofascial trigger points identified by palpation. Round adhesive electrodes will be used for the surface electrode application.
