NCT06738667

Brief Summary

Temporomandibular disorder (TMD) is a common musculoskeletal pain condition affecting the jaw, and acupuncture is often used for treatment, though its neurological mechanisms are unclear. This study investigates the neural mechanisms of acupuncture in TMD using functional MRI (fMRI), structural MRI (sMRI), and diffusion tensor imaging (DTI), alongside machine learning to predict treatment outcomes. This study aims to enhance understanding of acupuncture's effects on TMD and improve personalized treatment approaches.

Outcome Measures

Primary Outcomes (1)

  • Visual Analog Scale

    The VAS is a self-administered instrument, ranging from 0 (no pain at all) to 10 (worst imaginable pain).

    From baseline (week 0) to the end of treatment (week 4) and the end of follow-up period (week 16)

Secondary Outcomes (8)

  • Magnetic Resonance Imaging

    From baseline (week 0) to the end of treatment (week 4) and the end of follow-up period (week 16)

  • Effective response rate

    From baseline (week 0) to the end of treatment (week 4) and the end of follow-up period (week 16)

  • Jaw Opening and Movement

    From baseline (week 0) to the end of treatment (week 4) and the end of follow-up period (week 16)

  • Graded Chronic Pain Scale

    From baseline (week 0) to the end of treatment (week 4) and the end of follow-up period (week 16)

  • Jaw Function Limitation Scale-20

    From baseline (week 0) to the end of treatment (week 4) and the end of follow-up period (week 16)

  • +3 more secondary outcomes

acupuncture

EXPERIMENTAL

Patients in the acupuncture group will receive treatment at specified acupoints, performed by acupuncturists with at least five years of experience. The acupoints include bilateral Hegu (LI4), Yanglingquan (GB34), and affected-side Jiache (ST6), Xiaguan (ST7), and Tinggong (SI19).

Other: Acupuncture

SHAM COMPARATOR

Patients in the sham group will receive noninvasive acupuncture at the same acupoints as the acupuncture group. Sham needles, which resemble real needles but are blunt and slide within their handles, will be applied using the Park Sham device, secured to the skin with a self-adhesive pad. The procedure of manipulation is the same as for acupuncture, but without Deqi.

Other: Sham treatment

Interventions

Patients in the acupuncture group will receive treatment at specified acupoints, performed by acupuncturists with at least five years of experience. The acupoints include bilateral Hegu (LI4), Yanglingquan (GB34), and affected-side Jiache (ST6), Xiaguan (ST7), and Tinggong (SI19). Participants will lie supine, and the skin will be sterilized. Sterile stainless-steel needles (0.25 mm diameter, 40 mm length) will be inserted using a guide device and a self-adhesive pad. Needles will be manipulated for at least 10 seconds to induce Deqi. Participants will receive 30 minutes of acupuncture for twelve sessions (3 per week for 4 weeks).

The Park Sham device will be used for the sham acupuncture group. To maintain blinding, the acupuncture ritual will be identical in both groups, with the following exceptions: patients in the sham group will receive noninvasive acupuncture at the same acupoints as the acupuncture group. Sham needles, which resemble real needles but are blunt and slide within their handles, will be applied using the Park Sham device, secured to the skin with a self-adhesive pad. The procedure of manipulation is the same as for acupuncture, but without Deqi.
