Sciatica Can Follow You Through the Entire Day.
Sciatic pain can travel from the lower back or buttock into the leg, making sitting, standing, walking, driving, sleeping and working more difficult.
Pain Relief International believes pain relief is more than comfort. When pain interferes with movement and everyday activity, reducing that barrier can create greater opportunity for independence, productivity and participation.
Pain That Travels Can Affect Everything Around It.
Sciatica can affect more than the moment pain is felt. Difficulty sitting, standing or walking comfortably can influence work, sleep, transportation and ordinary daily activities.
Mobility
Walking, standing and changing position may become difficult when pain travels through the buttock or leg.
Sitting & Driving
Prolonged sitting can be uncomfortable for some people with sciatica, affecting commuting, driving, travel and desk work.
Sleep
Finding a comfortable position can be difficult when pain extends from the lower back or buttock into the leg.
Work & Daily Life
Pain can interfere with work, household responsibilities, recreation, caregiving and other everyday activities.
When Movement Is Limited, the Effects Can Spread Outward.
When pain makes it difficult for someone to sit, stand, walk, drive or work, other people may need to help with transportation, household responsibilities, caregiving or work.
Greater opportunity for comfortable movement, independence and everyday activity.
Potentially less assistance needed with transportation, household tasks and everyday responsibilities.
Greater opportunity to sit, stand, move and participate in work activities.
More opportunity for people to participate, contribute and remain connected to everyday life.
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 sciatic pain, position the unit over the area where the pain originates or is most strongly experienced. The unit can be repositioned as needed and may be used over clothing.
What Has NeuroCuple Been Studied For?
NeuroCuple technology has been evaluated in clinical research, including randomized studies involving patients undergoing total knee and hip arthroplasty.
Important Context for Sciatica
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 sciatica.
Sciatica can arise from different underlying conditions. 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.
Keep it available when pain becomes a barrier. The unit requires no batteries, charging or consumables and can be 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.
When Pain Is Reduced, the Possibilities Can Spread Outward.
Around the world, pain can become a barrier to work, education, caregiving, independence and participation — especially where access to pain treatment is limited.
Pain Relief International works to expand access to practical, reusable, drug-free pain relief in homes and communities. You can experience the technology yourself, make a charitable contribution, or do both.

Sciatica Pain Relief Without Medication
What is sciatica?
Sciatica describes pain associated with irritation or compression involving the sciatic nerve or its nerve roots. Pain commonly travels from the lower back or buttock into the leg and may occur with numbness, tingling or weakness.
What are some drug-free approaches to sciatica?
Depending on the cause and circumstances, drug-free approaches may include appropriate activity and exercise, physical therapy, rehabilitation strategies and nonpowered pain-relief technologies. Persistent or severe symptoms should be evaluated by 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 sciatic pain?
Position the unit over the area where the pain originates or is most strongly experienced. Because pain patterns can differ between individuals, the unit can be repositioned as needed.
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 sciatica?
The published clinical studies cited here evaluated NeuroCuple technology in postoperative orthopedic populations, including total knee and hip arthroplasty. Those studies should not be interpreted as direct clinical proof of effectiveness specifically for sciatica.
Does the PRI 4Ă—4 use batteries or electricity?
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?
Yes. The PRI 4Ă—4 Deployment Unit is reusable and designed to 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.
