Neck & Shoulder Pain Can Reach Into Almost Every Activity.
Turning your head, reaching, lifting, driving, working or simply finding a comfortable position to sleep can become more difficult when the neck or shoulder hurts.
Pain Relief International believes pain relief is more than comfort. When pain limits movement and everyday activity, reducing that barrier can create greater opportunity for independence, work, caregiving and participation in daily life.
Small Movements Become Hard to Ignore When They Hurt.
The neck and shoulders are involved in countless everyday movements. Pain in these areas can affect work, sleep, driving, lifting, reaching and routine activities throughout the day.
Movement
Turning the head, looking up or down, reaching overhead and moving an arm can become uncomfortable or difficult.
Work
Desk work, computer use, physical labor, lifting and repetitive movements can all become more difficult when the neck or shoulder hurts.
Sleep
Pain can make it difficult to find or maintain a comfortable sleeping position, adding fatigue to the burden of pain.
Daily Activities
Driving, dressing, carrying objects, household tasks, exercise and caregiving may all become harder when movement is painful.
When Everyday Movement Hurts, Everyday Life Can Change.
Pain that interferes with reaching, lifting, driving or working can affect more than one activity. Responsibilities may shift to family members, coworkers or caregivers.
Greater opportunity for movement, sleep, independence and everyday activity.
Greater opportunity to continue household tasks, caregiving and other family responsibilities.
Greater opportunity to remain active and engaged in desk, physical or repetitive 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.
Position the unit over or near the area where the neck or shoulder pain is being experienced. Because the location of pain can differ, 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 orthopedic surgery.
Important Context for Neck & Shoulder 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 neck or shoulder pain.
Neck and shoulder pain can arise from many different causes. 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.
Restoring Movement Can Help Restore Participation.
Pain can turn ordinary movements into barriers — working, lifting, driving, caring for family or simply getting through the day.
Pain Relief International works to expand access to practical, reusable pain relief in homes and communities, including places where conventional pain-management resources may be limited.
Reducing pain can mean helping someone return to work, care for family, regain independence or participate more fully in everyday life.

Neck & Shoulder Pain Relief Without Medication
What are some drug-free approaches to neck and shoulder pain?
Depending on the cause and circumstances, drug-free approaches may include appropriate activity or exercise, physical therapy, rehabilitation strategies and nonpowered pain-relief technologies. Persistent or severe pain 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 neck or shoulder pain?
Position the unit over or near the area where pain is being experienced. Because neck and shoulder pain can occur in different locations, 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 neck or shoulder pain?
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 neck or shoulder 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?
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.
