Introducing Quell™, a 100% drug free technology proven to fight pain1
PN 2204150 REV A
A new option for relief from chronic pain
Published evidence in support of intensive nerve stimulation:
• Lower Back and Leg Pain: Significant reduction in pain, as assessed by the visual analog scale2
• Diabetic Neuropathy: Significant reductions in pain and analgesic use3
• Fibromyalgia: Combined with exercise, decreased pain, fatigue, and stiffness4
Site of Pain Block- Activation of δ-opioid Receptors
Elevated GABA Concentration
Pain Signal
Dorsal Root Ganglion (DRG)
Nociceptive Neuron
SPINAL CORD
ROSTRAL VENTRALMEDULLA (RVM)
CAUDAL MIDBRAIN
Raphe Nuclei
Descending Pain Regulatory Pathway
Ascending PainPathway
Periacqueductal Gray Matter (PAG)
SpinothalamicTract
Dorsal Horn
Transcutaneous Electrical NerveStimulation Activates PAG
Pain A�erent Fiber
Quell stimulates dense clusters of sensory nerve fibers in the upper calf. This, in turn, activates descending pain inhibition systems in the brainstem.
Precise, high-frequency nerve stimulation triggers a neurotransmitter cascade, starting in the periaqueductal gray matter and progressing to the rostroventral medulla and ultimately the dorsal horn of the spinal cord.
Enkephalins, powerful endogenous opioids released during this process, inhibit pain signal transmission for a widespread analgesic response.
Enkephalins target different pain receptors than prescription opioids, activating δ-opioid receptors, while prescription opioids act on the μ-opioid system.
Unique new wearable design blocks pain in the body
