Outcome Measures
Primary Outcomes (1)
The difference in visual analogue scale (VAS) of temporomandibular pain
The primary outcome is the difference in VAS for TMJ pain between baseline and the primary end point (Week 6). VAS is an assessment index in which the patient records their pain on a 100mm line from 'no pain' at one end, and 'the most severe pain imaginable' at the other end.
Week 6
Secondary Outcomes (7)
Numeric rating scale (NRS) of TMJ pain and discomfort
Week 6
TMJ range of motion
Week 6
Korean version of Beck's Depression Index-Ⅱ (K-BDI-Ⅱ)
Week 6
Jaw Functional Limitation Scale (JFLS)

Study Arms (2)
Hominis placental pharmacopuncture
EXPERIMENTALThe Hominis placental pharmacopuncture group will receive 10 sessions of Hominis placental pharmacopuncture at 2 sessions/week for 5 weeks. A trained doctor of Korean medicine with at least 2 years clinical experience will administer JHG002 pharmacopuncture with a disposable syringe (0.5ml) directly into the designated sites, using a standardized method.
Transcutaneous electrical nerve stimulation
ACTIVE COMPARATORThe control group will receive 2 sessions/week of TENS for 5 weeks. A high-frequency, low-intensity stimulus of 50-100Hz and up to 15mA will be used, such that the patients feel a current but do not feel pain. At each treatment visit, a physiotherapist will administer the treatment to the bilateral temporomandibular joint for 15 minutes. Both centres will use the same TENS device-a BioTron-DX (D.M.C, Osan, South Korea).
Interventions
Hominis placental pharmacopuncture is human placental extract, which has been used in traditional Korean medicine to treat chronic diseases, including frailty, cough, anorexia, and fatigue, by enhancing the body's resistance.
Eligibility Criteria
You may qualify if:
- Patients with unilateral or bilateral TMJ pain
- Patients with VAS≥40mm for the area showing TMJ pain (for patients with bilateral pain, the side with worse pain)
- Patients complaining of persistent of sporadic TMJ pain for at least 3 months
- Patients diagnosed as myofascial TMD (Axis I: Group 1) based on the RDC/TMD diagnostic criteria\[5\]
- Patients aged 19-70 years on the date they sign the consent form
- Patients who provide consent to participate in the trial and return the informed consent form
You may not qualify if:
- Patients whose current pain episode developed or worsened because of a road traffic accident or traumatic injury
- Patients diagnosed in Group 2 or 3 of Axis I based on the RDC/TMD diagnostic criteria
- Patients who have undergone surgery related to the TMJ
- Patients with other chronic disease that could interfere with interpretation of the treatment effects or outcomes (e.g., rheumatoid arthritis, neoplastic disease, stroke, or myocardial infarction)
- Patients currently taking steroids, immunosuppressants, psychiatric drugs, or other drugs that could affect the study results
- Patients who have received HPP within the last month, or who have taken drugs that could affect pain, such as NSAIDs, within the last week
- Pregnant or breastfeeding women
- Patients who have finished participation in another clinical trial within the last month, who participated in another trial within 6 months of selection, or who are planning to participate in another clinical trial during the follow-up period
- Patients with a history of hypersensitivity after HPP
- Diabetic patients with uncontrolled blood glucose (fasting blood glucose ≥180mg/dl)
- Patients with AST (GOT) or ALT (GPT) at least 2 times the normal range at the testing centre
- Patients with creatinine at least 2 times the normal range at the testing centre
- Patients suspected to have organic disease
- Patients with cardiac, hepatic, renal, or other serious complications
- Patients with psychogenic disease
- +2 more criteria
