Learn the basic differences between TENS and EMS devices, what to compare and essential electrical-stimulation safety considerations.
What should you know?
The basics
TENS stands for transcutaneous electrical nerve stimulation and is commonly discussed in relation to pain-management applications. EMS stands for electrical muscle stimulation and is used to stimulate muscle contractions. Devices and intended uses differ.
What matters when comparing
Before buying, verify the manufacturer's intended use, electrode placement instructions, power settings, contraindications, and whether the exact model has relevant regulatory clearance. Clearance for one device does not establish clearance for another.
Practical considerations
Electrical stimulation is not suitable for everyone. People with implanted electronic devices, certain heart conditions, or other contraindications should consult a clinician. Do not apply electrodes across the chest, over the front of the neck, or to broken skin unless the device instructions explicitly permit a particular use.
Before you decide
Do not infer that a consumer device cures pain, heals injuries, or replaces clinical treatment.
