Background: As the number of patients who suffer from non-specific chronic neck pain (CNP) is increasing in the Republic of Korea, conservative treatments for patients with CNP have been spotlighted. Although several studies on thread embedding acupuncture (TEA) treatment have been published for the treatment of such patients, no randomized controlled trial has been reported that investigates the effectiveness and safety of the TEA treatment compared with other conservative treatments for the treatment of patients with CNP. Therefore, the purpose of this trial is to compare the effectiveness and safety of TEA to those of physical therapy (PT) for the treatment of patients with CNP.
Methods/design: This study is planned as a parallel design, randomized, controlled, assessor-blinded, clinical study. One hundred twenty-eight patients diagnosed with CNP will be randomly assigned to either the TEA group or the PT group in a 1:1 ratio. Participants in the TEA group will receive 4 sessions of TEA treatment, while those in the PT group will receive 8 sessions of PT treatment over 4 weeks. An assessment of effectiveness based on the outcomes of the Neck Pain and Disability Scale (NPDS), cervical spinal angle, Beck Depression Inventory II (BDI-II), Beck Anxiety Inventory (BAI), Patient Global Impression of Change (PGIC), EuroQol-Five Dimension 3 level version (EQ-5D-3L), and Pressure Pain Threshold (PPT) will be conducted at baseline, and at 5, 9, and 13 weeks. The primary outcome is the mean change in the NPDS at 9 weeks. Adverse events (AEs) will be recorded at every visit.
Discussion: The results of this study will be expected to provide useful information for the effectiveness and safety of TEA treatment compared to PT treatment for patients with CNP.
