Feasibility and Effects of Noninvasive Brain Stimulation on Pain Perception in People With Fibromyalgia
Transcranial Electrical Stimulation for Noninvasive Study of Pain Circuits in Patients With Chronic Pain
The goal of this interventional study is to learn whether noninvasive brain stimulation (NIBS) will have an effect on pain perception in people with fibromyalgia. The main questions it aims to answer are:
Do repeated sessions of NIBS lead to a reduction in perceived pain? Do repeated sessions of NIBS lead to an improvement in quality of life?
Researchers will compare different brain targets to see if effects are different between them.
Participants will receive repeated daily sessions of NIBS over 4 weeks with application of pressure pain algometry, and complete various questionnaires.

상세 설명
Participants will randomly receive primary motor cortex (M1) or occipital lobe NIBS over 2 weeks, and after a wash-out period will receive NIBS of the other target over 2 weeks. Each session will also evaluate pressure pain algometry, various questionnaires to assess changes in fibromyalgia symptoms and quality of life (up to 5 hours per session)
NIBS administration will consist of 1000 electrical pulses of <1 ms duration each.

|
Feasibility of the transcranial electrical stimulation protocol
기간: From end of the last study session until up to 6 months after.
|
Feasibility of the protocol will be measured quantitatively using the Feasibility of Intervention Measure (FIM) score.
Score ranges from 4 to 20, with higher scores indicating higher level of feasibility.
It will also be assessed qualitatively via participant interviews.
|
From end of the last study session until up to 6 months after.
|
|
Tolerability of transcranial electrical stimulation protocol
기간: Every day from enrollment until up to 6 months after the last study session.
|
Determined qualitatively from study-related participant attrition rate (%) and adherence to protocol (%).
|
Every day from enrollment until up to 6 months after the last study session.
|
|
Acceptability of transcranial electrical stimulation protocol
기간: From end of the last study session until up to 6 months after.
|
Acceptability of the protocol will be measured quantitatively using the Acceptability of Intervention Measure (AIM) score.
Score ranges from 4 to 20, with higher scores indicating higher level of acceptability.
It will also be assessed qualitatively via participant interviews.
|
From end of the last study session until up to 6 months after.
|
|
Pressure pain threshold (PPT)
기간: At every study session from Session 1 until the last study session.
|
PPT (in lbf) will be measured using a digital algometer, which will be used to press down on the participants' thumb nails and legs to assess pain sensitization throughout the study.
|
At every study session from Session 1 until the last study session.
