Effects of Auricular Acupressure on Relieving Pain in Postpartum Women With Episiotomy

November 30, 2025 updated by: HSIAO AI WEN
This randomized, single-blind controlled trial examined the effects of auricular acupressure on postpartum women who underwent episiotomy. A total of 86 participants were allocated to either an intervention group, which received routine care plus transparent auricular patches containing magnetic beads applied to selected acupoints, or a control group, which received identical patches without magnetic beads. The patches were applied for 48 hours after delivery. Perineal pain and its impact on daily activities were assessed at 2, 12, 24, and 48 hours postpartum, while satisfaction with perineal pain care was measured at 48 hours. Using independent t-tests, chi-square tests, and generalized estimating equations, the study evaluated whether auricular acupressure reduced perineal wound pain, lessened pain-related interference with daily activities, and improved satisfaction with perineal pain management.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

Yes

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: auricular patch containing magnetic beads
After placental delivery, the intervention group received routine care plus a transparent patented auricular patch containing magnetic beads, while the control group received a transparent patented auricular patch without magnetic beads. The selected acupoints included internal genitalia (TF2), external genitalia (HX4), Shenmen (TF4), sympathetic (AH6a), and subcortex (AT4).

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
perineal pain
Time Frame: At 2, 12, 24, and 48 hours postpartum
Structured questionnaires were used to assess perineal pain and its impact on daily activities at 2, 12, 24, and 48 hours postpartum.
At 2, 12, 24, and 48 hours postpartum

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
