Clinical Trial Summary

This study is a 2-arm parallel, assessor blinded, multi-centre, randomised controlled trial.


Description:

From 2 hospitals of Korean medicine, we will enrol 82 chronic TMD patients in Axis 1, Group Ⅰ according to RDC/TMD diagnostic criteria, and randomly allocate 41 patients each to an HPP group and a physical therapy (PT) group. Treatment will be administered in 10 rounds, after which there will be 4 follow-up visits (6, 9, 13, and 25 weeks from baseline). The primary end point is 6 weeks after baseline, and the primary outcome is the difference in Visual analogue scale (VAS) score for temporomandibular pain between baseline and Week 6. Secondary outcomes will be Numeric rating scale (NRS) scores for temporomandibular pain and discomfort, temporomandibular joint range of motion, Korean version of Beck's Depression Index-Ⅱ(K-BDI-II), Jaw Functional Limitation Scale (JFLS), Patien Global Impression of Change(PGIC), and quality of life. Using data on adverse events and cost-effectiveness in the two groups, we will perform a safety assessment and a cost-effectiveness analysis (economic assessment).

Outcome

Type Measure Description Time frame Safety issue
Primary 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 Numeric rating scale (NRS) of TMJ pain and discomfort The extent of TMJ pain and discomfort in the last week will be assessed using NRS. NRS is a pain scale in which the patient indicates their subjective pain as a whole number from 0 to 10. The participant is asked to report their TMJ pain and discomfort using NRS, where 0 indicates 'no pain or discomfort' and 10 indicates 'the most severe pain and discomfort imaginable'. Week 6
Secondary TMJ range of motion A Therabite Range of Motion Ruler will be used to measure the range of TMJ mouth opening and excursive movement; the measurement method will follow the guidelines provided by the International RDC/TMD Consortium. Week 6
Secondary Korean version of Beck's Depression Index-? (K-BDI-?) The BDI-? is an index for diagnosing depression, consisting of 21 questions related to sadness, guilt, suicidal ideation, and loss of interest. In this study, we will use the K-BDI-II, which has been demonstrated to be valid and reliable by a Korean research group. Week 6
Secondary Jaw Functional Limitation Scale (JFLS) The JFLS is an index assessing jaw function (mastication, mobility, and emotional and verbal expression) in the last month. The instrument consists of 20 questions, and each question is scored 0-10, where 0 points is 'no impairment' and 10 points is 'very severe impairment'. In this study, we will use the official Korean version of the 20-question JFLS, which has been demonstrated to be reliable. Week 6
Secondary Patient Global Impression of Change (PGIC) The PGIC is an index that assesses improvements in functional limitation caused by TMD in 7 grades. Participants rate the improvement in functional limitations after treatment on a 7-point Likert scale (1=Very much improved, 4=No change, 7=Very much worse). This index was originally developed for use in Psychology, but is currently used in various other medical fields to assess improvements in pain. Week 6
Secondary The five level version of EuroQol-5 Dimension (EQ-5D-5L) The EQ-5D-5L is a method of indirectly calculating the weights of certain health states for quality of life after a multidimensional investigation of health states, and is the most widely used instrument for this purpose. The EQ-5D-5L consists of 5 questions about current health state (mobility, self-care, usual activities, pain, anxiety/depression), and each question is scored on a 5-point Likert scale (1=no problems, 3=moderate problems, 5=severe problems). In this study, we will use the Korean version of the EQ-5D-5L, which has been demonstrated to be valid. Week 6
Secondary SF-12 The SF-12 is a shortened version of the Short Form-36 Health Survey (SF-36), which is a widely used instrument to assess health-related quality of life. The SF-12 consists of 12 questions across 8 domains, and higher scores indicate better health-related quality of life. In this study, we will use the Korean version of the SF-12, which has been demonstrated to be reliable and valid. Week 6
