Quell was created by a team of scientists and engineers at NeuroMetrix who are committed to empowering people to regain a high quality of life. It combines neurotechnology to treat chronic pain with a sophisticated app to personalize and control therapy, while tracking progress. Quell Wearable Pain Relief is patented non-invasive nerve stimulation technology that provides relief from chronic pain. It consists of a device and an electrode that attaches to the device. The device is worn on your upper calf, a few inches below the knee, and is controlled by a single button on your device or your smartphone. Quell provides pain relief by comfortably stimulating the nerves that carry normal, non-painful sensations to your brain, which decreases the perception of pain. Pain relief is initiated by simply clicking a button on the device. Each therapy session is 60 minutes. After your first session, therapy will automatically restart every other hour. Pain relief may begin in as little as fifteen minutes after the start of a therapy session and may last up to an hour following the end of a session. You have complete control and can start or end therapy anytime from your device or your smartphone.
