Chronic Temporomandibular Disorders (TMD)
Conditions
Interventions
Group A (Healthy Subjects):No intervention
only gait and electromyography tests are conducted under three states (no chewing, left-side chewing gum, right-side chewing gum), with retesting after 2 weeks
Group B (TMD Patients):Physical factor therapy: Ultrasound therapy
Temporomandibular Joint (TMJ) Manual Therapy
TMJ Mobilization Technique

Inclusion criteria
Inclusion criteria: Healthy individuals: 1. Age >= 18 and = 18 and = 3 months, and NPRS score between 3 and 7; 4. No severe oral structural abnormalities (no severe tooth loss, no severe bite disorder requiring orthodontic treatment); 5. Normal lower limb function (no lower limb movement injury, no lower limb fracture / ligament injury in the past 6 months, normal range of motion of all lower limb joints); 6. Voluntary to sign the informed consent form, able to understand and follow the test instructions, and able to complete the test procedures under three conditions (no chewing, mainly chewing on the left side, mainly chewing on the right side).
Exclusion criteria
Exclusion criteria: Healthy population: 1. Obvious abnormalities of the spine or lower limbs detected by examination (such as scoliosis, X-shaped legs, O-shaped legs, obvious flat feet or obvious high arches, etc.); 2. History of neurological diseases such as balance disorders, Parkinson's disease, stroke, or symptoms of dizziness, unsteady walking, or positive Romberg test; 3. History of strenuous exercise for more than 1 hour within 3 days, or taking drugs that may affect muscle movement or balance function before the test (such as muscle relaxants, sedative-hypnotics); ?Researchers consider it inappropriate to participate in this study. Chronic TMD patients: 1. Severe dentition defect (affecting chewing function), severe malocclusion requiring orthodontic treatment, or history of oral and maxillofacial surgery; 2. Received any treatment for TMD within 1 month (such as occlusal splint, botulinum toxin injection, physical therapy, etc.); 3. History of neurological diseases such as balance disorders, Parkinson's disease, stroke, or symptoms of dizziness, unsteady walking, or positive Romberg test; 4. History of strenuous exercise for more than 1 hour within 3 days, or taking drugs that may affect muscle movement or balance function before the test (such as muscle relaxants, sedative-hypnotics); 5. Researchers consider it inappropriate to participate in this study.
