How Does Quell Relieve Pain?

Quell uses transcutaneous electrical nerve stimulation (TENS) to stimulate sensory nerves in your leg with safe, painless, and precise electrical impulses to trigger a natural pain relief response. TENS devices like Quell have been used by physicians, physical therapists, and other health care professions for decades to manage pain.

Over 20 Years of Research

The company was started by Dr. Shai Gozani, M.D., Ph.D., while conducting research at MIT. NeuroMetrix has spent over 20 years developing technology to help physicians diagnose nerve disorders and, more recently, to address chronic pain.

With over 70 patents awarded since 1996, Quell is the product of this expertise and combines neurostimulation and digital health technologies to relieve chronic pain.

Quell is the most technologically advanced TENS device
