About this study
Official title: Accelerated Low-Intensity Focused Ultrasound (LIFU) for Chronic Pain and Generalized Anxiety Disorder: A Proof-of-Concept Case Series
A proof of concept case study to investigate accelerated LIFU protocol in chronic pain and anxiety populations.
Read the detailed description
A single-arm, open label, 2 cohort (chronic pain/GAD) case study with extended (6 months) follow-up following accelerated low-intensity focused ultrasound for neuromodulation.
- Conditions
- Chronic Pain, Generalized Anxiety Disorder
- Being tested
- Low Intensity Focused Ultrasound
- Medical subject headings
- Chronic Pain, Generalized Anxiety Disorder
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Low Intensity Focused UltrasoundDevice
Low-Intensity Focused Ultrasound applied multiple times in a single study visit.
| Study group | Role | What they receive |
|---|---|---|
| Low-intensity focused ultrasound for neuromodulation | Experimental | Accelerated (repeat) LIFU application for neuromodulation Receives: Device: Low Intensity Focused Ultrasound |
What is being measured
The primary outcome is the main question the study is designed to answer.
Safety - monitoring of possible symptoms
Symptom monitoring before and after LIFU applications and throughout 6 months of follow-up. Each symptom is presented with a likert scale (absent, mild, moderate, severe) - along with a free response option for any symptoms not included in the list.
Measured: Throughout study participation at multiple time points, approximately 6 months.
Changes in Chronic Pain - self report
Participants will complete the Brief Pain Inventory (BPI) at multiple time points throughout the 6 month period. This questionnaire asks participants to rate their pain on a 10 point scale (10 being the most pain).
Measured: Multiple timepoints throughout the 6 month experimental timeframe.
Changes in Anxiety - self report
Participants will complete the Beck Anxiety Inventory (BAI) at multiple time points before and after LIFU application to track changes in anxiety throughout the 6 month timeframe. The BAI probes different symptoms of anxiety and participants rate it on a likert scale (not at all, mildly, moderately, or severely).
Measured: Throughout the experimental timeframe, approximately 6 months.
