Individualized TCM Pattern-Based Thread-Embedding Acupuncture Plus Auricular Acupressure for Chronic Insomnia
Bewertung der Wirksamkeit von Fadenimplantat-Akupunktur in Kombination mit Ohrakupressur basierend auf den klinischen Syndromen der Traditionellen Chinesischen Medizin bei Patienten mit nicht-organischer Schlaflosigkeit
Chronic insomnia disorder is a common sleep disorder associated with impaired daytime functioning and may be accompanied by alterations in immune-inflammatory and gut-related biological processes. Traditional Chinese medicine (TCM) uses pattern differentiation to individualize treatment; however, the additional clinical value of pattern-based treatment compared with a standardized protocol remains insufficiently established.
This randomized controlled trial will evaluate whether individualized TCM pattern-based thread-embedding acupuncture combined with auricular acupressure improves sleep quality more effectively than the same therapeutic modalities delivered using a standardized fixed-point protocol in adults with chronic insomnia disorder.
Participants will be classified as having either Heart-Spleen Deficiency or Liver Qi Stagnation with Spleen Deficiency according to prespecified TCM diagnostic criteria and randomized 1:1 to individualized pattern-based treatment or standardized treatment.
The primary outcome is the change in Pittsburgh Sleep Quality Index (PSQI) score from baseline to the end of treatment. Secondary clinical outcomes include insomnia severity measured by the Insomnia Severity Index (ISI), gastrointestinal symptoms measured by the Gastrointestinal Symptom Rating Scale (GSRS), and adverse events.
Serum interleukin-6 (IL-6) and fecal calprotectin will be assessed as exploratory systemic and gut-related inflammatory biomarkers. These biomarkers are intended to explore biological correlates potentially relevant to gut-brain interactions and are not considered diagnostic markers of insomnia or direct measures of the microbiota-gut-brain axis.
Clinical outcomes will additionally be assessed at Week 10, four weeks after completion of scheduled treatment, to evaluate persistence of clinical effects.

Detaillierte Beschreibung
This is a randomized, participant- and outcome-assessor-blinded, active-controlled, parallel-group clinical trial enrolling 70 adults aged 40 to 75 years with Chronic Insomnia Disorder diagnosed according to the International Classification of Sleep Disorders, Third Edition (ICSD-3).
Eligible participants must also meet prespecified diagnostic criteria for one of two Traditional Chinese Medicine patterns:
- Heart-Spleen Deficiency, or
- Liver Qi Stagnation with Spleen Deficiency. Participants will be randomly allocated in a 1:1 ratio to an individualized TCM pattern-based treatment group or a standardized treatment group.
Individualized treatment group Participants will receive thread-embedding acupuncture and auricular acupressure using acupoints selected according to their prespecified TCM pattern diagnosis.
Standardized treatment group Participants will receive the same treatment modalities using a fixed set of acupoints applied irrespective of TCM pattern.
Thread-embedding acupuncture will be performed twice, at baseline and Week 4. Auricular acupressure using Vaccaria seeds will be initiated at baseline and renewed every 2 weeks during the 6-week treatment period. Participants will be instructed to self-massage the auricular points for 1-2 minutes per point, 3-5 times daily, particularly approximately 30 minutes before bedtime.
The active treatment period will last 6 weeks, followed by a 4-week post-treatment follow-up, with the final assessment at Week 10. The Week 10 assessment is intended to evaluate the persistence of clinical effects after treatment discontinuation.
Sleep outcomes will be assessed using the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI). Gastrointestinal symptoms will be assessed using the Gastrointestinal Symptom Rating Scale (GSRS). Adverse events will be monitored throughout the study.
Serum IL-6 and fecal calprotectin will be measured at baseline and Week 6. These biomarkers are considered exploratory mechanistic outcomes representing systemic and gut-related inflammatory activity. Because the study does not directly assess gut microbiota composition, microbial metabolites, intestinal permeability, or central nervous system biomarkers, IL-6 and fecal calprotectin will not be interpreted as direct measures or proof of a microbiota-gut-brain axis mechanism.
Biomarker sampling procedures Baseline biomarker samples will be collected before the first study intervention. If a participant has an acute febrile illness or clinically significant acute infection at a scheduled biomarker assessment, blood and stool sampling may be postponed within a prespecified allowable window according to the biomarker sampling standard operating procedure (SOP). For baseline assessments, the first study intervention will not be initiated until pretreatment biomarker samples have been collected. For the Week 6 assessment, biomarker sampling may be rescheduled within the prespecified allowable window without requiring withdrawal from the clinical study. The participant will remain in the study unless the acute illness otherwise meets a protocol-defined criterion for treatment discontinuation or study withdrawal.
Prespecified analytic components
The study includes two distinct prespecified analytic components:
-
Randomized treatment-effect analysis The primary analysis will compare the clinical efficacy of individualized TCM pattern-based treatment with the standardized treatment protocol according to randomized treatment assignment. The primary clinical endpoint will be the between-group difference in change in PSQI score from baseline to Week 6.
Changes in ISI, GSRS, IL-6, fecal calprotectin, and adverse events will be evaluated as secondary or exploratory outcomes.
-
Exploratory baseline phenotyping analysis
A separate exploratory analysis using pretreatment data only will examine whether Heart-Spleen Deficiency and Liver Qi Stagnation with Spleen Deficiency represent clinically and biologically distinguishable phenotypes. This analysis will examine:
- differences in insomnia severity between the two TCM patterns;
- differences in baseline serum IL-6;
- differences in baseline fecal calprotectin;
- associations of IL-6 with insomnia severity;
- associations of fecal calprotectin with insomnia severity; and
- whether these biomarker-insomnia associations differ according to TCM pattern. The baseline phenotyping analysis will not evaluate randomized treatment efficacy or post-treatment treatment effects.
All mechanistic and baseline phenotyping analyses will be considered exploratory and hypothesis-generating.

Aktiver Komparator: Standardized Fixed-Point Protocol
Participants will receive the same therapeutic modalities-thread-embedding acupuncture and auricular acupressure-using a fixed set of acupoints irrespective of TCM pattern diagnosis. Thread-embedding acupuncture will be administered at baseline and Week 4. Auricular acupressure using Vaccaria seeds will be initiated at baseline and renewed every 2 weeks during the 6-week treatment period. Participants will receive the same self-massage instructions as participants in the individualized treatment group. |
Thread embedding acupuncture is performed twice at a 4-week interval using the points HT7 (Shenmen), PC6 (Neiguan), SP6 (Sanyinjiao), GB20 (Fengchi), and Anmian. Auricular acupressure using Vaccaria seeds is applied and replaced every 2 weeks on the points Shenmen (TF4), Subcortex, Occiput, Forehead, Kidney, and Endocrine. Participants are instructed to perform self-massage on the ear seeds 3-5 times daily for 1-2 minutes per point, particularly 30 minutes before bedtime. Thread embedding acupuncture is performed twice at a 4-week interval using absorbable sutures. The selection of acupoints is strictly tailored to the participant's Traditional Chinese Medicine (TCM) syndrome differentiation: Heart-Spleen Deficiency: The procedure utilizes the points BL15 (Xinshu), BL20 (Pishu), ST36 (Zusanli), SP6 (Sanyinjiao), and ST25 (Tianshu). Liver Qi Stagnation with Spleen Deficiency: The procedure utilizes the points BL18 (Ganshu), LR3 (Taichong), GB34 (Yanglingquan), SP6 (Sanyinjiao), and PC6 (Neiguan). Auricular acupressure using Vaccaria seeds (ear seeds) is applied to reflex points on the ear and replaced every 2 weeks throughout the 8-week study period. The selection of ear points is customized based on the TCM syndrome. Heart-Spleen Deficiency: The points include Heart (CO15), Spleen (CO13), Stomach (CO4), TF4 (Shenmen), and Subcortex (AT4). Liver Qi Stagnation: The points include Liver (CO12), Gallbladder (CO11), Sympathetic (AH6a), TF4 (Shenmen), and Subcortex (AT4). Participants are instructed to perform self-massage on the ear seeds for 1-2 minutes per point, 3-5 times daily, particularly 30 minutes before bedtime. |

Change in Pittsburgh Sleep Quality Index (PSQI) Global Score From Baseline to End of Treatment
Zeitfenster: Baseline to Week 6 (End of Treatment)
|
The Pittsburgh Sleep Quality Index consists of 19 self-rated items grouped into seven components. Each component is scored from 0 to 3, producing a global score ranging from 0 to 21. Higher scores indicate poorer sleep quality. The primary treatment effect will be evaluated as the between-group difference in change in PSQI global score from baseline to the prespecified end-of-treatment assessment. |
