Low Intensity Focused Ultrasound for Patients With Fibromyalgia

6. november 2026 opdateret af: Patrick Finan, PhD, University of Virginia

Early Feasibility Study of Low Intensity Focused Ultrasound Neuromodulation in Patients With Fibromyalgia

The overall goal of this study is to establish the safety and feasibility of low intensity transcranial focused ultrasound (liFU) stimulation for patients with fibromyalgia. We will also attempt to investigate the efficacy of liFU for pain and related symptoms and to compare whether liFU effects differ for people trained in different types of meditation.

Detaljeret beskrivelse

Following informed consent (Session 1), participants will participate in a baseline assessment (Session 2), during which they will receive a full battery of questionnaires, as well as a task-based fMRI and a baseline CT scan (the latter used for brain mapping in preparation of the liFU intervention). They will also be randomized during this session. The study is divided into two phases; in Phase 1 they will undergo four virtual sessions of a meditation intervention (either Savoring Meditation or Slow Breathing Meditation), depending on their group allocation (Session 3 to Session 6). They will then receive another assessment composed of questionnaires and a task-based fMRI (Session 7). In Phase 2 they will receive the liFU intervention (Session 8 to Session 11). At Session 11, they will also receive a post-treatment assessment composed of questionnaires and a task-based fMRI. A follow-up assessment (Session 12) four weeks after their final liFU intervention will be composed of questionnaires.

Deltagergruppe / Arm
Intervention / Behandling
Eksperimentel: Low Intensity Focused Ultrasound + Savoring Meditation (liFU+SM)

In this arm, participants first receive training in Savoring Meditation, a positive affect-focused behavioral intervention designed to enhance positive affect and support chronic pain self-management. Participants complete four 20-minute telehealth training sessions over approximately two weeks delivered by a trained interventionist. After completing the meditation training portion, participants in the liFU + SM arm complete four sessions of low-intensity focused ultrasound targeting the nucleus accumbens during which they actively practice Savoring Meditation concurrent with the sonication.

Aktiv komparator: Low Intensity Focused Ultrasound

In the liFU arm, participants first spend 4 telehealth sessions undergoing training in a slow breathing meditation practice. Subsequently, participants complete four in-person liFU treatment sessions over four weeks, with sequential bilateral sonications targeting the nucleus accumbens during each session. In this arm, participants do not engage in any concurrent meditation practice or other behavioral intervention during sonication. Rather, they only receive liFU sonication during those sessions.

Clinical pain impact
Tidsramme: Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).

Changes in clinical pain impact will be evaluated using the Pain, Enjoyment of life, and General activity (PEG) Scale, which is a hybrid measure of pain severity and pain interference. This scale is comprised of 3 items, each rated on a numerical scale from 0-10. The total score is averaged on a scale from 0-10.

Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).
Clinical pain severity
Tidsramme: Assessed at Session 2 (week 0), Session 7 (week 3), Sessions 8-11 (Weeks 3-6; immediately after each intervention and 24h after each intervention), weekly throughout weeks 7-11, and Session 12 (week 11).

Changes in clinical pain severity will be evaluated using the Brief Pain Inventory (BPI). Average pain in the past 24 hours is rated on a scale from 0-10.

Assessed at Session 2 (week 0), Session 7 (week 3), Sessions 8-11 (Weeks 3-6; immediately after each intervention and 24h after each intervention), weekly throughout weeks 7-11, and Session 12 (week 11).
Pain catastrophizing
Tidsramme: Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).

Changes in pain catastrophizing will be evaluated using the Pain Catastrophizing Scale (PCS). The PCS is a 13-item scale, each noted on a Likert like scale from 0-4. Total scores are obtained by summing all scores, to obtain a score between 0 and 52.

Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).
Fatigue
Tidsramme: Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).

Changes in fatigue levels will be evaluated using the Fatigue Severity Scale (FSS). The FSS is a 9-item scale, each noted on a Likert like scale from 1-7. Total scores are obtained by summing all scores, to obtain a score between 0 and 63.

Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).
Fibromyalgia Impact
Tidsramme: Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).

Fibromyalgia Impact will be assessed using the Fibromyalgia Impact Questionnaire Revised (FIQ-R). The FIQ-R is a 21-item scale where each item is rated on a scale from 0-10 and the overall score is calculated as the addition of all items and then normalized relative to a predefined level of importance for each item. Total scores range from 0-100.

Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).
Fibromyalgia Severity
Tidsramme: Assessed at Session 2 (week 0) and Session 7 (week 3).

Fibromyalgia Severity will be assessed with the Widespread Pain Index (WPI) and the Symptom Severity Scale (SSS). The WPI counts the number of tender points reported and can range from 0 to 19. The SSS assesses 3 items on a Likert-like scale (from 0-3) as well as 3 items on a binary Yes/No scale (Yes=1, No=0). The SSS scale yields a score ranging from 0-12. In total, the WPI-SSS score is calculated by adding the WPI and the SSS score, yielding a final total score ranging from 0-31.

Assessed at Session 2 (week 0) and Session 7 (week 3).
Sleep quality
Tidsramme: Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).

Sleep quality will be assessed using the Insomnia Severity Index (ISI) and the Pittsburgh Sleep Quality Index (PSQI). The ISI is a 7-item Likert-like scale (ranging from 0-4). The total score is obtained by adding all item scores, yielding a total possible range of 0-28. The PSQI is a scale comprising of 7 different components, each of which may range from 0-3. The total score is obtained by adding all component scores, yielding a total possible range of 0-21.

Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).
Positive Affect
Tidsramme: Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).

Changes in Positive Affect will be assessed using the Positive and Negative Affect Schedule - Expanded Form (PANAS-X). The PANAS-X consists of 60 items rated on a Likert-like scale (ranging from 1-5). Total scores are separated as General negative affective scores (ranging 10-50), General Positive Affective Scores (ranging 10-50) and a series of emotional scales with varying ranges.

Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).
Hedonic Capacity
Tidsramme: Assessed at Session 2 (week 0), Session 7 (week 3), and Session 12 (week 11).
