About this study
Official title: Effectiveness of an Acupressure Band for Primary Dysmenorrhea in College Students: A Randomized Controlled Trial
This study aims to investigate the effectiveness of an acupressure band in improving primary dysmenorrhea among college students. Primary dysmenorrhea is characterized by cramping lower abdominal pain during menstruation and is often accompanied by symptoms such as nausea, fatigue, and headache. It is also one of the leading causes of academic and work absenteeism among women of reproductive age. Previous studies have shown that acupressure applied to the Sanyinjiao (SP6) acupoint can alleviate menstrual pain. In addition, current clinical research has mainly focused on auricular acupressure using Vaccaria seeds, while relatively few studies have explored their application on body acupoints. Therefore, this study focuses on the application of Vaccaria seeds on the Sanyinjiao (SP6) acupoint to evaluate their effects on primary dysmenorrhea.
To provide continuous and stable acupoint stimulation, this study utilizes an intervention device combining Vaccaria seeds with a compression band, together with acupressure stimulation.

This study adopts a single-blind randomized controlled trial design. A total of 30 participants will be randomly assigned to either the experimental group or the control group (compression band only group). The study consists of four menstrual cycles, including one baseline menstrual cycle followed by three consecutive menstrual cycles of home-based intervention.
Outcome measures include the Visual Analog Scale (VAS) for pain intensity, the Menstrual Distress Questionnaire (MEDI-Q) for menstrual-related symptoms and distress, and heart rate variability (HRV), monitored using the ANS Watch as an indicator of autonomic nervous system activity. Statistical analyses will be conducted to compare differences between the experimental and control groups, as well as between pre- and post-intervention measurements, in order to evaluate the clinical potential of the acupressure band for primary dysmenorrhea management.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Compression band with vaccaria seedsDevice
The intervention utilizes an adjustable band with three Vaccaria seeds forming a 5 mm circular stimulation area, designed to cover the Sanyinjiao (SP6) acupoint region. The seeds are fixed on the inner side of the band. In the first session, a medical student research assistant trained in acupuncture will teach the participant how to locate the SP6 acupoint (3 cun or 4 finger-widths above the tip of the medial malleolus, at the posterior border of the tibia). For subsequent home-based intervention, participants will locate and apply the band by themselves. The band consists of 60% non-elastic and 40% elastic materials with a 3 cm velcro buffer.
Compression band onlyDevice
The control group utilizes the same adjustable band design but without any Vaccaria seeds on the inner side. In the first session, a medical student research assistant will guide the participant to locate the Sanyinjiao (SP6) region on the calf for standardization. Participants will wear and apply the band by themselves at home following the same instructions. The band consists of 60% non-elastic and 40% elastic materials, with a 3-cm Velcro buffer.
| Study group | Role | What they receive |
|---|---|---|
| Compression Band Only | Sham comparator | Participants will wear the compression band only, without Vaccaria seeds, and apply the band to the same location to serve as a control. Receives: Device: Compression band only |
| Compression Band with Vaccaria Seeds | Experimental | Participants will wear a compression band combined with vaccaria seeds applied to the Sanyinjiao (SP6) acupoint to receive continuous acupressure stimulation during menstruation. Receives: Device: Compression band with vaccaria seeds |
What is being measured
The primary outcome is the main question the study is designed to answer.
Change from Baseline in Average Menstrual Pain Intensity Measured by the Visual Analog Scale (VAS)
Menstrual pain intensity will be assessed using a 10-cm Visual Analog Scale (VAS), ranging from 0 (no pain) to 10 (worst pain). During each menstrual period, participants will record their average and maximum pain intensity each evening. The average menstrual pain intensity for each menstrual cycle will be calculated from the daily VAS records and used for the primary outcome analysis.
Measured: From baseline (Cycle 1) through the end of the third intervention menstrual cycle (Cycle 4); menstrual cycle length is 21-35 days.
Secondary outcomes (1)
Change from Baseline in Menstrual Distress Questionnaire (MEDI-Q) Total Score
Menstrual-related symptoms and distress will be assessed using the Menstrual Distress Questionnaire (MEDI-Q). The questionnaire includes 25 items assessing physical and psychological symptoms associated with menstruation. The MEDI-Q Total Score is calculated by summing the scores of all 25 items, with a possible range from 0 to 125, with higher scores indicating greater menstrual distress. For this study, the recall period will be modified from the previous year to the previous three months to correspond with the intervention period. Change in the MEDI-Q Total Score from baseline to the end of the intervention will be evaluated.
Measured: At baseline (Cycle 1) and at the end of the third intervention menstrual cycle (Cycle 4); menstrual cycle length is 21-35 days.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
This study aims to investigate the effectiveness of an acupressure band in improving primary dysmenorrhea among college students. Primary dysmenorrhea is characterized by cramping lower abdominal pain during menstruation and is often accompanied by symptoms such as nausea, fatigue, and headache. It is also one of the leading causes of academic and work absenteeism among women of reproductive age. Previous studies have shown that acupressure applied to the Sanyinjiao (SP6) acupoint can alleviate menstrual pain. In addition, current clinical research has mainly focused on auricular acupressure using Vaccaria seeds, while relatively few studies have explored their application on body acupoints.

Questions about this trial
What is this clinical trial studying?
A study testing Compression band with vaccaria seeds and Compression band only in people with Primary Dysmenorrhea (PD), run by China Medical University Hospital at 1 site in Taiwan.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: looking for participants now, as of the sponsor's last update on 31 Aug 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Taiwan. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
