How does it work? Quell is worn in a strap that wraps around the upper calf, sending electrical pulses through the skin to the sensory nerves that in turn signal the brain to trigger the body's natural pain relief response, blocking pain signals throughout the body.

Quell® is a 100% drug free wearable pain relief device that uses prescription-strength nerve stimulation technology to deliver relief from chronic pain. Quell is a FDA Class II medical device. It can used day and night use, so you can experience pain relief while you're active or asleep.

Quell is an advanced, wearable version of TENS technology. Like traditional TENS units, Quell uses electrical nerve stimulation in order to provide pain relief. Since Quell is wearable and fully automated, therapy can be delivered during the day while active and at night while sleeping.

The Quell is a wearable device aimed to ease chronic pain from conditions like fibromyalgia, diabetic neuropathy, sciatica, and osteoarthritis. It's a small, square device that sits in a velcro pocket with an electrode snapped inside.

The Quell Fire Sprinkler System is designed for cold storage and/or unheated warehouses using a "surround and drown" method to save your building and goods stored. Quell Fire System is a double interlock pre-action system design scenario developed for the protection of high piled storage.

For most people, TENS is a safe treatment with no side effects. Some people may be allergic to the pads and their skin may become red and irritated. Speak to your GP, physiotherapist or pharmacist if you have concerns. You may need to take a short break from using TENS.

The Quell design concept uses listed sprinkler hardware and components in a double interlock pre-action system configuration as an alternative means of design to allow for the protection of high piled storage in buildings as high as 48ft without the need of in-rack sprinkler systems in a high piled storage ...

Serious complications are very rare , but can include:

• epidural hematoma.
• nerve injury.
• infection, which may require removal of the stimulator.
• paralysis.

Electrical stimulation (ES) is the most commonly used non-surgical treatment. Most studies used low-frequency ES to promote nerve regeneration, but the method and frequency range of ES need to be standardized because high-frequency ES will aggravate nerve damage (6).

Spinal cord stimulation and peripheral nerve field stimulation are considered generally safe, with the potential risks mainly related to the surgical procedures required for a trial period or long-term therapy.

What are the side effects of transcutaneous electrical nerve stimulation?

• burning or irritation.
• allergic reaction.
• contact dermatitis.
• Nausea and dizziness.
• Muscle spasms.
• Headache.

Fortunately, electrotherapy - specifically electrical muscle stimulation (EMS) - can help prevent atrophy by stimulating muscles to contract. Sometimes, EMS is used to stimulate muscles to contract, while a TENS machine is used to help reduce the pain associated with atrophy.
