Menstrual Pain Can Take Time Away From Everyday Life.
Painful periods can make it harder to concentrate, sleep, attend school, work, care for family or participate fully in everyday activities.
Pain Relief International believes pain relief is more than comfort. When recurring pain becomes a barrier to participation, reducing that barrier can help women and girls remain engaged in education, work, family life and their communities.
A Recurring Pain Can Create a Recurring Barrier.
Menstrual pain can return month after month. When symptoms are significant, the effects can reach into education, employment, sleep, family responsibilities and everyday participation.
School & Learning
Pain can make it more difficult to attend class, concentrate, study and participate fully in educational activities.
Work
Menstrual pain can make a workday more difficult, whether the job requires prolonged sitting, standing, physical activity or sustained concentration.
Sleep & Concentration
Pain can interfere with rest and make it harder to concentrate on tasks during the day.
Daily Participation
Family responsibilities, exercise, social activities and everyday routines may become harder when menstrual pain is significant.
When Pain Repeats, Its Impact Can Repeat Too.
Menstrual pain may be temporary, but when it returns regularly, the lost hours of school, work, caregiving and participation can accumulate over time.
Greater opportunity to remain active, comfortable and engaged during the menstrual cycle.
Greater opportunity to attend class, concentrate, study and participate in school activities.
Greater opportunity to remain present at work and continue everyday family and caregiving responsibilities.
More opportunity for women and girls to participate consistently in the activities and communities that matter to them.
A Different Approach to Pain Relief
The PRI 4×4 Deployment Unit uses NeuroCuple® technology — a passive, nonpowered approach to pain relief built around a patented array of capacitive junctions.
The technology is designed to interact through non-invasive capacitive coupling with the local bioelectrical environment associated with pain perception.
NeuroCuple does not deliver powered electrical stimulation into the body. It requires no batteries, charging, wires or medication, and it does not require direct skin contact.
For menstrual pain, position the unit over the lower abdomen where the pain is being experienced. The unit can be repositioned as needed and may be worn over clothing.
What Has NeuroCuple Been Studied For?
NeuroCuple technology has been evaluated in clinical research, including randomized studies involving patients undergoing orthopedic surgery.
Important Context for Menstrual Pain
The published clinical studies cited by Pain Relief International evaluated NeuroCuple technology in postoperative orthopedic populations. Those studies provide clinical evidence for the technology, but they should not be interpreted as direct clinical proof of effectiveness specifically for menstrual pain.
Menstrual pain can also have different causes and levels of severity. Pain Relief International therefore separates the published clinical evidence for the technology from claims about conditions that have not yet been directly evaluated in those studies.
Experience It Yourself. Help Bring Relief to Others.
The PRI 4Ă—4 Deployment Unit gives you an opportunity to experience the same durable, reusable, drug-free technology used by Pain Relief International in its humanitarian work.
Because it requires no batteries, charging or consumables, the reusable unit can be kept available for recurring periods of pain and repositioned when needed.
You receive your own reusable PRI 4Ă—4 Deployment Unit. 100% of proceeds from device purchases fund Pain Relief International deployments to help expand access to pain relief.
Please note: purchasing a device is not a tax-deductible donation.
Pain Shouldn't Decide Who Gets to Participate.
When recurring pain interferes with education, work and daily life, its impact can extend far beyond the hours when pain is present.
Pain Relief International works to expand access to practical, reusable pain relief — including in communities where access to conventional pain-management resources may be limited.
Helping reduce pain can mean helping someone return to class, remain at work, care for family or simply participate more fully in everyday life.

Menstrual Pain Relief Without Medication
What is menstrual pain?
Menstrual pain, often called period pain or dysmenorrhea, commonly involves cramping or pain in the lower abdomen around the time of menstruation. The intensity and duration can vary considerably between individuals.
Can menstrual pain affect school or work?
Significant menstrual pain can interfere with concentration, physical activity, sleep and ordinary daily activities. For some people, this can make attending or participating fully in school or work more difficult.
What are some drug-free approaches to menstrual pain?
Drug-free approaches may include heat, appropriate physical activity or exercise, relaxation strategies and other non-drug pain-management approaches. Persistent, unusually severe or changing menstrual pain should be discussed with an appropriate healthcare professional.
What is NeuroCuple®?
NeuroCuple is a passive, nonpowered pain-relief technology built around an array of capacitive junctions designed to interact through non-invasive capacitive coupling with the local bioelectrical environment associated with pain perception. It requires no drugs, batteries, charging or wires.
Where should the PRI 4Ă—4 be positioned for menstrual pain?
Position the unit over the lower abdomen where menstrual pain is being experienced. The unit can be repositioned as needed and may be worn over clothing.
Does NeuroCuple require direct skin contact?
No. The PRI 4Ă—4 Deployment Unit may be used over clothing or dressings and does not require direct skin contact.
Has NeuroCuple been clinically studied specifically for menstrual pain?
The published clinical studies cited here evaluated NeuroCuple technology in postoperative orthopedic populations. Those studies should not be interpreted as direct clinical proof of effectiveness specifically for menstrual pain.
Does the PRI 4Ă—4 require batteries or charging?
No. The device is passive and nonpowered. It requires no batteries, charging or wires and does not deliver powered electrical stimulation into the body.
Can the PRI 4Ă—4 be reused for future menstrual cycles?
Yes. The PRI 4Ă—4 Deployment Unit is reusable and can be kept available and repositioned when needed.
How much does the PRI 4Ă—4 Deployment Unit cost?
The PRI 4Ă—4 Deployment Unit is $80. You receive your own reusable unit, and 100% of proceeds from device purchases fund Pain Relief International deployments. Purchasing the device is not a tax-deductible donation.
