Vestibular Innovation in Pain 2 (VIPR)

February 13, 2026 updated by: Michael H Kaplan, Icahn School of Medicine at Mount Sinai

Vestibular Innovation in Pain: A Randomized Controlled Trial

Fibromyalgia is the most common centralized pain disorder, affecting up to 3% of the population. Current treatments are incompletely effective, often poorly tolerated, and costly: there remains an urgent need for novel, effective, and well-tolerated therapy. Preliminary data suggests that vestibulocortical stimulation (VCS), or irrigating the external ear canal with temperate water, could rapidly improve pain and quality of life in this cohort. The VIPR trial will assess the efficacy of a single session of VCS - a safe & cost-effective bedside technique using a plastic syringe and temperate water - relative to sham in treating pain & improving quality of life using validated patient-reported outcomes.

Design Details

  • Primary Purpose: Treatment
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: Single

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Vestibulocortical Stimulation
Participants will receive 50 cc of either warm or cold water irrigated into the right external ear canal at 1-2 cc/second.
VCS is a non-invasive bedside procedure using temperate water, and a plastic syringe (no needles). With the participant laying supine, temperate water is irrigated into the external ear canal at 1-2 cc/second.
Other Names:
  • VCS
Sham Comparator: Sham Stimulation

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Pain numeric rating scale (NRS)
Time Frame: Baseline and 1 week
Change in NRS as compared to baseline. Pain numeric rating scale (NRS), Full score on scale from 0-10 (0 = no pain; 10 = pain as bad as you can imagine). Higher scores indicate more pain.
Baseline and 1 week

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in Pain numeric rating scale (NRS)
Time Frame: 30 minutes, 24 hours, 2 weeks, 3 weeks, 4 weeks
Change in Pain numeric rating scale (NRS) (acute and long term). Pain numeric rating scale (NRS), Full score on scale from 0-10. 0 = no pain; 10 = pain as bad as you can imagine. Higher scores indicate more pain.
30 minutes, 24 hours, 2 weeks, 3 weeks, 4 weeks
Overall Well Being Scale
Time Frame: 30 minutes
Numeric rating scale scored from 0-10, 0 = lowest quality of life, 10 = best imaginable. Higher score indicates better health outcomes.
30 minutes
Patient Global Impression of Change (PGIC)
Time Frame: 24 hr, 1 week, 2 weeks, 3 weeks, 4 weeks
Full scale scored from 0-7 scale. 0 = No change or condition has worsened; 7 = A great deal better with considerable improvement. Higher score indicates better health outcomes.
24 hr, 1 week, 2 weeks, 3 weeks, 4 weeks
Brief Pain Inventory (Short-Form; BPI-SF)
Time Frame: 24 hrs, 1 week, 2 weeks, 3 weeks, 4 weeks

Validated patient reported outcome that measures both pain intensity and pain interference. The BPI-SF uses numeric rating scales (0-10) to evaluate worst, least, average, and current pain intensity, as well as pain interference with general activity, mood, walking ability, normal work, relations with others, sleep, and enjoyment of life.

Pain intensity, Subscale scored from 0-10 NRS: 0 = no pain, 10 = worst pain imaginable.

Pain interference, Subscale scored from 0-10 NRS: 0= Does not interfere, 10 = Completely interferes.

24 hrs, 1 week, 2 weeks, 3 weeks, 4 weeks
Patient Reported Outcomes Measurement Information System (PROMIS-29)
Time Frame: 1 week, 2 weeks, 3 weeks, 4 weeks
PROMIS-29 includes 29 items covering seven health domains-physical function, anxiety, depression, fatigue, sleep disturbance, ability to participate in social activities, and pain interference-each measured with four items, plus a separate 0-10 numeric rating scale for pain intensity. Each health domain is assessed with questions on a 1-5 scale, with the valence of 1 and 5 being dependent on the domain being assessed. PROMIS-29 domains are scored using T-scores, standardized to a mean of 50 and a standard deviation of 10 based on the U.S. general population. Higher scores indicate more of the concept being measured. However, whether a higher score reflects better or worse health depends on the domain.
1 week, 2 weeks, 3 weeks, 4 weeks
Composite Autonomic Symptom Score-31 (COMPASS-31)
Time Frame: 1 week, 2 weeks, 3 weeks, 4 weeks
COMPASS-31 quantifies symptoms of autonomic dysfunction across six weighted domains: orthostatic intolerance, vasomotor, secretomotor, gastrointestinal, bladder, and pupillomotor functions. The 31 items yield a total score ranging from 0 to 100, with higher scores indicating greater severity of autonomic symptoms.
1 week, 2 weeks, 3 weeks, 4 weeks
