For fibromyalgia patients with high pain sensitivity

The spectrum of pain sensitivity in fibromyalgia patients ranges from normal sensitivity comparable to healthy controls to severe disabling sensitivity. Patients with high pain sensitivity report hyperalgesia and allodynia, such as excessive tenderness to touch, painful reactions to cold and/or heat, and pain in response to light touch. Patients with fibromyalgia and high pain sensitivity have a lower quality of life and greater disease impact than those with normal pain sensitivity.

Quell Fibromyalgia was studied in a double-blind, randomized, sham-controlled trial1

  • 119 subjects with physician diagnosed fibromyalgia who also met the American College of Rheumatology 2010 diagnostic criteria.
  • Subjects randomized to active or sham treatment for 3-months.
  • Analyses conducted on the intention-to-treat population (ITT, N=119) and a prespecified high pain sensitivity subgroup (N=60). The primary endpoint was a statistically significant mean difference in the 3-month PGIC2 scores between the treatment arms.

Key Study Results (in high pain sensitivity subgroup3)


58% of subjects in the active arm compared to 30% in the sham arm (p=0.025) reported at least moderately better symptoms and overall quality of life.2


58% of subjects in the active arm compared to 28% in the sham arm (p=0.019) reported a clinically meaningful reduction (≥15%) in fibromyalgia impact.4


60% of subjects in the active arm compared to 18% in the sham arm (p<0.001) reported at least a moderate reduction (≥30%) in pain intensity.5,6

Note: The percentage of patients expected to obtain meaningful symptom improvement in routine clinical practice has not yet been determined.

Mechanisms of action

The specific biological mechanisms by which Quell Fibromyalgia reduces lower extremity pain and other symptoms of fibromyalgia are uncertain. However, several neurological processes may be relevant.

  • The biological trigger for pain relief from transcutaneous electrical nerve stimulation is believed to be persistent peripheral nerve stimulation at an intensity above the sensory threshold.7
  • The original model for how sensory nerve stimulation produces pain relief was proposed by Melzack and Wall in 1965. Their theory stipulated that activation of large diameter sensory nerves (Aβ fibers) closes a “pain gate” in the spinal cord that inhibits the onward transmission of pain signals carried by nociceptive afferents (C and Aδ) to the brain.8
  • An expansion of the pain gate theory attributes the clinical benefits of transcutaneous electrical nerve stimulation to a reduction in central excitation and an enhancement of central inhibition. This model is aligned to the understanding of fibromyalgia as condition of central sensitization, which is an overamplification of pain and other sensory signals in the central nervous system.9
