About this study
Official title: A Randomized, Double-blind, Placebo-controlled, Study to Evaluate the Effect of a REN Wearable Device on Conditioned Pain Modulation (CPM) in Patients With Migraine and/or Fibromyalgia
Migraine and Fibromyalgia (FM) are chronic pain disorders characterized by altered central pain processing and impaired endogenous pain inhibition. FM presents with widespread musculoskeletal pain, fatigue, sleep disturbance, and cognitive symptoms and is strongly associated with central sensitization. Migraine similarly involves dysfunction of central inhibitory and descending pain modulation, with evidence of abnormal cortical excitability, impaired sensory habituation, and alterations in pain-related evoked potentials.
Conditioned Pain Modulation (CPM) is a measure of the body's endogenous pain-inhibitory mechanism, based on the phenomenon whereby the pain evoked by one painful stimulus (the test stimulus) is reduced by the concurrent application of a second, remote nociceptive stimulus (the conditioning stimulus). It is widely regarded as a proxy for the function of descending pain-modulatory pathways.
Read more
CPM is used as an experimental biomarker of descending pain inhibition across chronic pain conditions, including fibromyalgia and migraine. Studies consistently demonstrate reduced inhibitory responses in both migraine and fibromyalgia compared with healthy controls, indicating a robust deficit in descending pain modulatory systems. Combining a contact heat test stimulus (TS) with a cold pressor conditioning stimulus (CS) is a widely used and validated CPM paradigm.
Nerivio, a Remote Electrical Neuromodulation (REN) device, is a non-invasive, non-pharmacological therapy indicated for the acute and preventive treatment of migraine. The REN device is worn on the upper arm and delivers peripheral electrical stimulation to activate CPM-related descending inhibitory pathways and reduce migraine pain. This distal stimulation approach is designed to activate CPM-related circuits by recruiting brainstem pain-regulatory centers and modulating central nociceptive processing.
This randomized, double-blind, placebo-controlled trial is designed to assess the effect of a single REN session on CPM and cortical pain processing in adults with migraine or fibromyalgia. Using a standardized CPM induction protocol, the study will evaluate changes in behavioral CPM responses, before, during, and after REN vs. sham stimulation in patients with migraine or fibromyalgia. This study aims to clarify whether REN enhances descending pain inhibition and pain processing in populations with impaired endogenous pain modulation.
Read the detailed description
The Nerivio device is a prescription use, self-administered device for use in the home environment for the acute and/or preventive treatment of migraine above the age of 8 years old. It is a wireless, wearable, battery-operated stimulation unit controlled by a smartphone software application.
The study hypothesis is that the REN wearable can induce the CPM mechanism, leading to a reduced pain response to a painful stimulus, and that the reduced pain response following REN stimulation will be larger than following Placebo (sham) stimulation, similar to the standard CPM response demonstrated by exposure to cold water. The placebo device will be identical to the active Nerivio device in its appearance and administration, differing only in the electrical waveform which is designed to activate the CPM mechanism (REN) or not (Placebo).
Pain levels will be measured using standard Numeric Rating Scale (NRS) between 0 and 10.
This hypothesis will be tested using Active or Sham devices as the Conditioned Stimuli (CS), with a heat stimulus serving as the Test Stimulus (TS) for pain induction.
Where:
TS is a painful stimulation (heat on the arm) P1 is the pain response to TS (baseline P2 is the pain response to TS following a standard CS (hand in cold water) P5 is the pain response to TS 15 minutes following a REN treatment (stimulation on the upper arm) CPM1 is the difference between TS pain response following the standard CS (cold water) and the pain response to the TS alone (CPM1 = P2-P1) CPM4 is the difference between TS pain response following the standard CS (cold water) and the pain response following 15 minutes after REN treatment (CPM4 = P5-P1)
The study hypothesis is that REN will lead to a larger CPM response than the placebo stimulation. That is, the CPM response following REN (CPM4 REN = P5 REN - P1 REN) will be larger than the CPM response following Placebo (CPM4 Placebo = P5 Placebo - P1 Placebo), relative to the standard CPM response to cold water in each arm:
H0: (CPM4 REN - CPM1 REN) - (CPM4 Placebo - CPM1 Placebo) = 0 H1: (CPM4 REN - CPM1 REN) - (CPM4 Placebo - CPM1 Placebo) ≠ 0
In other words:
H0: (P5 REN - P2 REN) - (P5 Placebo - P2 Placebo) = 0 H1: (P5 REN - P2 REN) - (P5 Placebo - P2 Placebo) ≠ 0
The analysis will compare REN and Placebo as CS across various TS, relative to the effect of cold water - a defined, well-established CS for CPM induction.
The study design includes the following:
Setting of Test Stimulus (TS): Participant will undergo thermal pain stimulus. 10-second thermal stimulus will be applied to the volar forearm using a contact thermode. Pain levels from repeated TS applications will be collected using NRS. This pain level is defined as P1.
Standard Conditioning Stimulus (Cold water hand immersion). TS will be applied under the presence of Conditioning Stimulus (CS). The participant's hand \& wrist will be immersed for up to 30 seconds in a plastic container filled with cold water at 8-10°C. Pain levels from repeated TS applications will be collected using NRS. This pain level is defined as P2. CPM1 will be calculated by comparing P2 to P1.
Randomization procedure
Following completion of the baseline CPM assessment, qualified participants will be randomized to either:
- Active REN group
- Placebo (Sham) group
A break of 15 minutes will be taken prior to starting the treatment phase to eliminate the CPM effect by cold water.
A device (REN or Placebo) will serve as the Conditioning Stimulus, and treatment will be conducted for 45 minutes. TS will be applied and pain levels will be collected using NRS from repeated TS applications at mid treatment (P3; 20 minutes into treatment), end of treatment (P4; 40 minutes into treatment), and post treatment (P5; 15 minutes following the end of the treatment).
Interim analysis will be performed following the recruitment of 40 participants,

| Study group | Role | What they receive |
|---|---|---|
| Active REN treatment | Active comparator | This arm will use the active REN device as the Conditioned Stimulus (CS) to the thermal Test Stimulus (TS) that will be applied at 20, 40, and 60 minutes following the initiation of the treatment with the Active REN device. Receives: Device: Remote Electrical Neuromodulation (REN) device |
| Placebo REN treatment | Placebo comparator | This arm will use the Placebo device as the Conditioned Stimulus (CS) to the thermal Test Stimulus (TS) that will be applied at 20, 40, and 60 minutes following the initiation of the treatment with the Placebo device. Receives: Device: Remote Electrical Neuromodulation (REN) device |
What is being measured
The primary outcome is the main question the study is designed to answer.
Between-groups (Active vs Placebo) difference in mean change of Conditioned Pain Modulation (CPM) activity from post-treatment (CPM4) to baseline (CPM1), measured by Numeric Rating Scale (NRS, 0-10).
Difference between the Active and Placebo groups in the mean change of pain levels following Test Stimulus (TS) at 15 minutes post-treatment with the REN wearable as the Conditioned Stimulus (CS) versus pain levels following Test Stimulus (TS) under cold water as Conditioned Stimulus (CS):
(CPM4 REN - CPM1 REN) - (CPM4 Placebo - CPM1 Placebo) = (P5 REN - P2 REN) - (P5 Placebo - P2 Placebo)
The pain range is between 0 to 10. CPM4 is the difference between the pain level with REN as CS and pain prior treatment without Conditioned Stimulus (CS). CPM1 is the difference between the pain level with Cold Water as Conditioned Stimulus (CS) and pain prior treatment without Conditioned Stimulus (CS). Thus, the expected value is a negative number and higher number means higher CPM activity.
Measured: 1 hour
Secondary outcomes (2)
Between-groups difference in mean change of pain levels from post-treatment Test Stimulus (P5) to baseline Test Stimulus (P1), measured by Numeric Rating Scale (NRS, 0-10).
Difference between the Active and Placebo REN groups in the mean change of pain levels following Test Stimulus at 15 minutes post-treatment with REN as Conditioned Stimulus (CS) and baseline pain levels following Test Stimulus only, without Conditioned Stimulus (CS):
(P5 REN - P1 REN) vs. (P5 Placebo - P1 Placebo)
The pain range is between 0 to 10. the higher the number, the higher the pain. The expected value is a negative number and higher number means higher CPM activity.
Measured: 1 hour
Between-group difference in mean change of pain levels following Test Stimulus (TS) under cold water as Conditioned Stimulus (CS) (P2) to baseline Test Stimulus only (P1), measured by Numeric Rating Scale (NRS, 0-10).
Difference between the Active and Placebo REN wearable groups (prior randomization) in the mean change of pain levels following Test Stimulus under cold water as Conditioned Stimulus (CS), and baseline pain levels following Test Stimulus only (P2-P1), This comparison will determine the CPM response of the participants PRIOR to randomization.
CPM1 REN vs CPM1 Placebo = (P2 REN - P1 REN) vs (P2 Placebo - P1 Placebo)
The pain range is between 0 to 10. the higher the number, the higher the pain. The expected value is a negative number and higher number means higher CPM activity.
Measured: 15 minutes

Primary outcome
Between-groups (Active vs Placebo) difference in mean change of Conditioned Pain Modulation (CPM) activity from post-treatment (CPM4) to baseline (CPM1), measured by Numeric Rating Scale (NRS, 0-10).
Time frame: 1 hour
Difference between the Active and Placebo groups in the mean change of pain levels following Test Stimulus (TS) at 15 minutes post-treatment with the REN wearable as the Conditioned Stimulus (CS) versus pain levels following Test Stimulus (TS) under cold water as Conditioned Stimulus (CS): (CPM4 REN - CPM1 REN) - (CPM4 Placebo - CPM1 Placebo) = (P5 REN - P2 REN) - (P5 Placebo - P2 Placebo) The pain range is between 0 to 10. CPM4 is the difference between the pain level with REN as CS and pain prior treatment without Conditioned Stimulus (CS). CPM1 is the difference between the pain level with Cold Water as Conditioned Stimulus (CS) and pain prior treatment without Conditioned Stimulus (CS). Thus, the expected value is a negative number and higher number means higher CPM activity.
2 secondary outcomes
