About this study
Official title: Investigation of Bowel Motility Changes Following Electroacupuncture at NP82 (Tongbian) and SP15 (Daheng) Acupoint Pair in Healthy Volunteers
This study aims to investigate how a specific combination of electroacupuncture points, Tongbian (NP82) and Daheng (SP15), affects bowel movements in healthy volunteers. Constipation is a significant health issue, especially for post-stroke patients, and current treatments like laxatives often have unwanted side effects. The researchers want to determine if stimulating these two acupuncture points can objectively increase the frequency of bowel activity.
Participants will undergo a three-stage procedure: a 30-minute period of baseline bowel sound recording, followed by 20 minutes of electroacupuncture stimulation at the specific points, and a final 30-minute recording period after the intervention. Throughout the study, an advanced digital stethoscope (3M™ Littmann® CORE) will be used to record bowel sounds objectively. This data will then be analyzed to measure any significant changes in bowel motility caused by the acupuncture.
Read the detailed description
Background and Rationale:
Bowel motility is a fundamental physiological function regulated by the autonomic nervous system. This study explores the potential of electroacupuncture (EA) to modulate this activity using a unique acupoint combination: Dai Hoanh (SP15), a classic point known for regulating the Spleen and Stomach, and Thong Tien (NP82), a newly proposed "extra point" specifically indicated for treating paralysis-related constipation in traditional literature. The study aims to provide the first modern scientific evidence for the effectiveness of NP82 in stimulating bowel motility.
Methodology:
The study follows a before-and-after intervention design involving 30 healthy volunteers. To ensure objective measurement, bowel sounds are recorded using the 3M™ Littmann® CORE Digital Stethoscope, which amplifies sounds and allows for computerized analysis, overcoming the subjectivity of traditional auscultation.
The procedure consists of three phases:
- Baseline Phase: Continuous 30-minute recording of bowel sounds to establish a physiological reference.
- Intervention Phase: Simultaneous 20-minute recording during EA. Sterile needles (0.30×40mm) are inserted into NP82 and SP15 points until "De Qi" sensation is achieved. Stimulation utilizes a dense-disperse wave at a 10 Hz frequency, with intensity adjusted (0.1-1 mA) based on participant tolerance.
- Post-intervention Phase: Continuous 30-minute recording after needle removal to evaluate sustained effects.
Blinded Outcome Assessment Note:
Although the clinical phase of this trial is formally registered as open-label (None/Open) due to its single-arm pre-post interventional design, a rigorous blinded outcome assessment was implemented during data analysis. The raw digital acoustic recordings were completely de-identified, randomized, and assigned arbitrary codes. The independent clinical experts responsible for manual bowel sound annotation and validation were fully masked to the participants' identities and the chronological sequence of the recording phases (baseline, active electroacupuncture, or post-intervention).
Data Analysis:
Automated signal preprocessing, ARMA-based event segmentation, and acoustic parameter extraction will be executed using Python programming software (version 3.10 or later) utilizing the SciPy and NumPy packages. All subsequent statistical analyses will be performed using R statistical software (version 4.3.0 or later; R Core Team, Vienna, Austria). Since acoustic bowel motility parameters do not exhibit a normal distribution (evaluated via the Shapiro-Wilk test), non-parametric paired Wilcoxon signed-rank tests will be utilized for all pairwise comparisons across the three experimental phases (baseline vs. active intervention, baseline vs. post-intervention, and active intervention vs. post-intervention). Continuous variables will be reported as Medians with Interquartile Ranges (IQR). A p-value of < 0.05 will establish the threshold for statistical significance for all tests

Electroacupuncture at NP82 (Tongbian) and SP15 (Daheng)Procedure or surgery
Also called EA at NP82 and SP15 points
The intervention is performed by practitioners with at least 3 years of experience. Sterile acupuncture needles (0.30×40mm) are inserted vertically into the Tongbian (NP82 - located 3 cun lateral to the umbilicus) and Daheng (SP15 - located 4 cun lateral to the umbilicus) acupoints. Insertion depth ranges from 20 to 65 mm depending on the participant's body type, aiming to achieve the "De Qi" sensation (aching, heaviness, and tension). Electrical stimulation is applied using a Hwato SDZ-III device with a dense-disperse wave at a frequency of 10 Hz for 20 minutes. The current intensity is adjusted (0.1-1 mA) until a mild muscle vibration is visible without causing pain to the participant.
| Study group | Role | What they receive |
|---|---|---|
| Electroacupuncture Group | Experimental | This single group of 30 healthy volunteers will undergo a three-phase sequential protocol where each participant serves as their own control[cite: 139, 140, 161]. The procedure includes: (1) a 30-minute baseline bowel sound recording; (2) a 20-minute electroacupuncture session at acupoints NP82 and SP15 with simultaneous recording; and (3) a 30-minute post-intervention recording to evaluate sustained effects[cite: 171, 172, 179, 181, 182]. Bowel sounds are captured objectively using a 3M™ Littmann® CORE Digital Stethoscope. Receives: Procedure: Electroacupuncture at NP82 (Tongbian) and SP15 (Daheng) |
What is being measured
The primary outcome is the main question the study is designed to answer.
Bowel Sound Interval (SSI)
SSI is the time interval between the end of one bowel sound event and the start of the next. Bowel sounds are recorded and quantified using the 3M™ Littmann® CORE Digital Stethoscope and analyzed with Stata 17.0 software to determine changes in bowel motility.
Measured: Continuous recording across three phases: Baseline (30 minutes before intervention), During Intervention (20 minutes), and Post-intervention (30 minutes).
Secondary outcomes (3)
Minimum SSI Ratio (SSIR)
SSIR is calculated as the ratio of the minimum Bowel Sound Interval (SSI) during or after the intervention (Ba) to the minimum SSI before the intervention (Bb). SSI values are derived from digital recordings of bowel sounds captured by a 3M™ Littmann® CORE Digital Stethoscope. The analysis focuses on 10-minute windows within each phase to determine the maximum increase in bowel motility compared to the baseline.
Measured: The total study duration is 80 minutes, consisting of: (1) Baseline phase: 30 minutes before intervention; (2) Intervention phase: 20 minutes during electroacupuncture; and (3) Post-intervention phase: 30 minutes after needle removal.
Bowel Sound Duration Ratio (BSDR)
Defined as the percentage of the total analytical window duration occupied by active bowel sound events. To account for the unequal durations of the study phases, this metric is calculated using a phase-dependent denominator T as follows: BSDR (%) = (Total BS Duration / T) * 100%, where T = 30 minutes for the baseline and post-intervention phases, and T = 20 minutes for the active electroacupuncture phase
Measured: Continuous recording across three phases: Baseline (30 minutes), Active Electroacupuncture (20 minutes), and Post-intervention (30 minutes)
Bowel Sound Frequency
Defined as the number of independent bowel sound events detected per minute within each study phase. This metric is computed as the total count of bowel sound events divided by the phase-specific window duration T (where T = 30 minutes for the baseline and post-intervention phases, and T = 20 minutes for the active electroacupuncture phase)
Measured: Continuous recording across three phases: Baseline (30 minutes), Active Electroacupuncture (20 minutes), and Post-intervention (30 minutes)
