Diadynamic current combined with jaw exercises for bruxism

The Effect of Diadynamic Current Combined With Rehabilitation in Patients With Bruxism: A Randomized Controlled Trial

NA · Inonu University · NCT07241728

This trial will see if adding diadynamic electrical stimulation to a 6-week, thrice-weekly jaw exercise program reduces pain and improves jaw strength and movement in adults with bruxism.

What this trial studies

Adults diagnosed with bruxism and jaw pain (VAS ≥3) are randomly assigned by sealed envelope to a control group receiving a structured exercise program or to an experimental group receiving the same exercises plus diadynamic current at each session. Both groups attend supervised in-person exercise sessions three times per week for six weeks. Outcomes include pain intensity (VAS), pressure pain threshold (algometer), muscle strength (hand-held dynamometer), bite force (pinch meter), and maximal mouth opening (caliper). Patients with pacemakers, systemic or neurological disease, recent physical therapy, or current use of muscle relaxants/analgesics are excluded.

Who should consider this trial

Good fit: Adults (18+) with a clinical diagnosis of bruxism who report jaw pain of 3 or higher on the VAS and can attend supervised sessions are ideal candidates.

Not a fit: People with pacemakers or implantable defibrillators, active infections, recent physical therapy or complementary treatments, systemic/neurological/psychiatric disorders, or current use of muscle relaxants or NSAIDs are excluded and would not benefit from this protocol.

Why it matters

Potential benefit: If successful, adding diadynamic current to exercises could reduce jaw pain and improve strength and opening more than exercises alone.

How similar studies have performed: Diadynamic current has shown some positive effects for musculoskeletal pain in prior physiotherapy studies, but its specific benefit for bruxism is not well established.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria: The study will include patients of both genders who have been clinically diagnosed with bruxism over the age of 18 and who report pain around the jaw (3 or higher on the VAS), and who have provided informed consent.

Exclusion Criteria: Patients who have previously used physical therapy or complementary-alternative medicine methods for similar complaints, those with neurological or psychiatric disorders, those with systemic diseases, those with pacemakers or implantable defibrillators; those with a history of cancer, those with an acute infection in the relevant area, those with a history of trauma to the jaw area, those using muscle relaxants, analgesics, or non-steroidal anti-inflammatory drugs, those who have participated in another study within the last 6 months, and individuals who do not agree to participate in the study will be excluded.
