Therapy TENS Units | Drug-Free Pain Relief Devices

Therapy TENS units deliver drug-free pain relief through gentle electrical nerve stimulation. These FDA-cleared devices help manage back pain, joint discomfort, muscle soreness, and chronic pain conditions without medication.

TENS (Transcutaneous Electrical Nerve Stimulation) works by sending low-voltage electrical pulses through electrode pads placed on the skin. These pulses interrupt pain signals traveling to the brain and stimulate the release of endorphins—your body's natural painkillers.

Our therapy TENS units combine TENS with EMS (Electrical Muscle Stimulation) for comprehensive pain management and muscle recovery. TENS targets nerve pathways for pain relief, while EMS contracts muscles to reduce spasms, improve circulation, and support rehabilitation.

The iReliev devices in our collection offer dual-channel output for treating multiple areas simultaneously. Choose from 14 pre-programmed therapy modes designed for different pain types and body areas. Adjustable intensity levels let you customize treatment to your comfort level.

These portable units include everything needed for home therapy: the device, electrode pads in multiple sizes, lead wires, and detailed placement guides. Rechargeable batteries provide hours of cordless use—perfect for treatment during daily activities.

Therapy TENS units are particularly effective for:
• Lower back pain and sciatica
• Neck and shoulder tension
• Knee and joint pain
• Post-workout muscle recovery
• Chronic pain management

For EMF-conscious users, our selected TENS devices minimize electromagnetic emissions beyond the therapeutic zone while delivering effective treatment.

Frequently Asked Questions

What is the difference between a TENS unit and a muscle stimulator?
TENS (Transcutaneous Electrical Nerve Stimulation) targets nerves to block pain signals and release endorphins for pain relief. EMS (Electrical Muscle Stimulation) targets muscles to cause contractions for strength, recovery, and rehabilitation. Our devices combine both TENS and EMS functions.
How often should I use a therapy TENS unit?
Most people use TENS therapy for 15-30 minute sessions, 1-3 times daily as needed for pain relief. Always follow the device instructions and consult your healthcare provider for chronic conditions. TENS is safe for regular use but should not be used continuously.
Where do I place TENS unit pads for back pain?
For lower back pain, place electrode pads on either side of the spine at the pain site, about 1-2 inches apart. Never place pads directly on the spine. The included placement guide shows optimal positions for different pain areas including back, neck, shoulders, and joints.
Is TENS therapy safe to use at home?
Yes, FDA-cleared TENS units are safe for home use when following instructions. Avoid using on the head, throat, chest (over heart), or during pregnancy without medical guidance. Do not use if you have a pacemaker or other implanted electrical device.
How long does it take for TENS therapy to work?
Many people feel pain relief during or immediately after a TENS session. The electrical stimulation blocks pain signals and triggers endorphin release within minutes. Effects typically last 1-4 hours after treatment, though results vary by individual and condition.
