Frequently Asked Questions
Are smart TENS units safe?
When used according to instructions and after consulting a clinician for certain conditions, TENS is generally safe for most people; avoid use with pacemakers, certain heart conditions, or pregnancy unless advised otherwise.
How often should I use a TENS unit?
Typical sessions run 15–30 minutes up to several times per day depending on comfort and clinician advice; start with short sessions to find a tolerable level.
Do TENS units cure chronic pain?
TENS provides temporary pain relief and symptom management but is not a cure; it works best as part of a comprehensive treatment plan including exercise and medical care.
What is the difference between TENS and EMS?
TENS focuses on pain modulation using sensory-level stimulation, while EMS induces stronger contractions aimed at muscle activation and rehabilitation.
Can I use TENS while sleeping?
Most manufacturers advise against using TENS during sleep due to safety and skin irritation risks; follow the device instructions and clinician recommendations.
How often do electrode pads need replacing?
Pad lifespan varies with skin prep and storage but typically lasts several weeks to a few months; replace when adhesion or conductivity declines.
