Thread Embedding Plus Auricular Acupressure for Non-Organic Insomnia Based on Traditional Medicine Pattern Differentiation

Официальное название

Evaluation of the Efficacy of Thread Embedding Acupuncture Combined With Auricular Acupressure Based on Traditional Chinese Medicine Clinical Syndromes in Patients With Non-Organic Insomnia

Обзор

Non-organic insomnia is a prevalent disorder that significantly impairs quality of life, characterized by difficulty initiating or maintaining sleep alongside daytime functional decline. This condition is particularly common among adults facing chronic stress, which increases the risk of chronic diseases and dysregulates the Microbiota-Gut-Brain Axis (MGBA)-a bidirectional communication system between the central nervous system and the gut microbiota. Prolonged sleep deprivation and stress can trigger inflammatory responses and gut dysbiosis, which in turn exacerbate emotional and sleep disturbances. While conventional sedative-hypnotics often carry side effects and risks of dependency, traditional medicine interventions are emerging as potential sustainable solutions. This study evaluates the efficacy of thread embedding combined with auricular acupressure based on individualized traditional Chinese medicine syndrome differentiation, while clarifying the relationship between clinical sleep improvement and changes in MGBA-related inflammatory markers, specifically interleukin-6 and calprotectin. The goal of this clinical trial is to evaluate the clinical efficacy and preliminarily investigate the mechanisms of action-via the Microbiota-Gut-Brain Axis-of individualized Traditional Chinese Medicine (targeting Heart-Spleen Deficiency and Liver Qi Stagnation syndromes) using thread embedding acupuncture combined with auricular acupressure to improve sleep quality in patients with insomnia, compared to a non-individualized protocol. The main questions it aims to answer are: * Does the combined method of thread embedding acupuncture and auricular acupressure based on syndrome differentiation improve sleep quality more effectively than the standardized protocol? * Is there a significant difference in the change of IL-6 and Calprotectin levels following treatment in the intervention group compared to the control group? * Does post-treatment clinical improvement correlate with the reduction of these inflammatory markers? Participants will: * Receive thread embedding acupuncture sessions every 4 weeks and have ear seeds (auricular acupressure) replaced every 2 weeks . Self-massage the ear seeds for 1 to 2 minutes several times each day, especially before bedtime. * Complete assessments of sleep quality (PSQI, ISI) and digestive health (GSRS) every 2 weeks through week 8. * Provide blood and stool samples at the start and end of the study to measure inflammation markers. * Be monitored for any adverse effects, such as local pain, dizziness, or needle fainting, during the trial period.

Подробное описание

Participants and Methods: A randomized, single-blind, controlled trial will be conducted with 70 participants, aged 40 to 75 years, residing in Ho Chi Minh City, who exhibit symptoms of chronic non-organic insomnia based on ICSD-3 criteria. Participants were required to meet the inclusion criteria and not fall under any exclusion criteria.

Randomization and Grouping: Participants will be randomly assigned into two groups in a 1:1 ratio using a permuted variable block randomization method. The intervention group will receive individualized Traditional Chinese Medicine (TCM) syndrome-based therapy. This involves thread embedding acupuncture using absorbable sutures and auricular acupressure using Vaccaria seeds applied to specific points tailored to either Heart-Spleen Deficiency or Liver Qi Stagnation syndromes. The control group will receive a standardized protocol using the same methods but with a fixed set of acupoints regardless of TCM syndrome.

Procedure and Assessments: Both groups will be provided with instructions on how to self-massage the auricular seeds for 1-2 minutes, 3-5 times daily, particularly 30 minutes before bedtime. The intervention will last for 8 weeks, with thread embedding acupuncture performed twice at 4-week intervals and auricular seeds replaced every 2 weeks. Clinical outcomes will be assessed using the PSQI, ISI, and Gastrointestinal Symptom Rating Scale (GSRS). To investigate the Microbiota-Gut-Brain Axis (MGBA) mechanisms, laboratory data including serum interleukin-6 (IL-6) and fecal calprotectin will be collected at baseline and after 8 weeks. Adverse effects, such as local pain, dizziness, or needle fainting, will be carefully monitored and recorded at week 2, 4, 6 and 8.
