How to Choose a TENS Unit
Key features to consider before buying
Massage Programs
Look for 8+ pre-set programs. Different waveforms target acute pain, chronic pain, muscle relaxation, and endorphin release.
Output Channels
2-channel units treat one area. 4-channel devices stimulate multiple muscle groups — ideal for full back or bilateral pain.
Power Source
Rechargeable lithium batteries save $50+/year vs disposables. USB-C charging adds convenience for daily use.
Electrode Pads
Self-adhesive pads last 15-30 uses. Larger pads (2"x4") distribute current better for deep tissue pain relief.
Frequently Asked Questions
What is the best TENS unit for chronic back pain?
For chronic back pain, look for a TENS unit with at least 8 massage modes, adjustable intensity levels, and large electrode pads. Dual-channel devices allow you to target the lower back and upper back simultaneously. Units with both TENS and EMS modes provide pain relief plus muscle relaxation.
Are TENS units safe to use at home?
Yes, FDA-cleared TENS units are safe for home use when following manufacturer guidelines. TENS therapy is drug-free, non-invasive, and has been used for decades in physical therapy. However, avoid use if you have a pacemaker, implanted defibrillator, epilepsy, or are pregnant without medical approval.
How much should I spend on a TENS unit?
Budget TENS units ($20-40) work well for occasional use and offer basic pain relief. Mid-range units ($40-80) include more programs, rechargeable batteries, and better build quality. Premium units ($80-150+) feature wireless electrode pads, app connectivity, and professional-grade stimulation patterns.
What is the difference between TENS and EMS?
TENS (Transcutaneous Electrical Nerve Stimulation) targets sensory nerves to block pain signals and is used for pain management. EMS (Electrical Muscle Stimulation) targets motor nerves to cause muscle contractions, used for muscle strengthening and recovery. Many modern devices offer both TENS and EMS modes.
How often can I use a TENS unit?
Most people can safely use a TENS unit for 15-30 minute sessions, multiple times per day. For chronic pain, consistent daily use often provides the best results. Always start at the lowest intensity and take breaks between sessions to prevent skin irritation from electrode pads.
