BUYING GUIDE
TENS vs EMS — What is the Difference?
TENS targets nerves to block pain signals and is used for pain relief. EMS targets muscles to cause contractions and is used for recovery and strengthening. Some units combine both. For pure pain relief, TENS is what you want.

Electrode Pad Placement
Place pads on either side of the pain area, not directly on the spine, heart, or throat. For lower back pain, place two pads vertically on each side of the spine. Consult the included placement guide for specific conditions.
