Plain English Summary

Background and study aims
Conditions of the musculoskeletal system, which affect joints, muscles ligaments and bones, are common and often painful. It is hugely frustrating for sufferers and can affect many aspects of their lives. We used to think that the pain was directly due to the pain signals from the joints or other tissues where the pain is being experienced. There is now evidence that this is not the only explanation for the pain and it may be related to changes in the chemical transmitters involved in the body’s pain detection system in the brain. Magnetic resonance imaging of the brain can be used to show how patients may have different brain responses to pain, even though their symptoms may be very similar. We will subgroup patients according to information about the symptoms that a patient is experiencing, as well as measurements of their pain thresholds as well as their brain-based responses to pain. In turn, this may help us to predict who will find one type of treatment more helpful than a different one. In the future, we hope that this will help more patients to manage their symptoms better.

Who can participate?
This study will focus on patients who have been diagnosed with either fibromyalgia or inflammatory arthritis and have been advised to start a new treatment by the doctors looking after them.

What does the study involve?
The study will follow patients for a period of 12 months after starting a new treatment (this may be a standard medication used for arthritis, or a programme of exercise combined with talking therapies). Many of the visits will be conducted alongside planned appointments at the hospital for their routine clinical care, but some extra research visits will take place in the research centre at the John Radcliffe Hospital where brain scans are done for research purposes.

What are the possible benefits and risks of participating?
Participants will not benefit directly from taking part in this study, but we hope that the information we get from this study will help to improve the treatment of musculoskeletal pain in the future.

Taking part in this study will require participants to attend the hospital for more visits than they would otherwise need. The sensory testing may cause minor, temporary discomfort but participants will be in control of the triggers applied and be free to stop the assessment at any
point in time.
MRI is safe and non-invasive and does not involve any ionising radiation (x-rays). However, because they use a large magnet to work, MRI scans are not suitable for everybody. Because of this, participants will be asked pre-screening safety questions to help determine if they are able to take part. Some people scanned in MRI scanners, especially 7 Tesla scanners, may experience a mild dizzy sensation as they are moved into the scanner. This is normal and the sensation starts to go away as soon as you are in the scanner. Occasionally a possible abnormality may be detected. In this case, we would have the scan checked by a doctor. If the doctor felt that the abnormality was medically important, the participant would be contacted directly and recommended to have a hospital (NHS) diagnostic scan arranged. All information is kept strictly confidential.

Study information

Scientific title

Characterisation of pain in patients with musculoskeletal disease: a prospective, longitudinal, observational study.


Study hypothesis

1. To investigate whether patients with inflammatory arthritis and features of centrally driven pain have reduced chance of responding to treatment.
2. To investigate the features of centrally driven pain, detected through multi-modal assessment, in patients with a range of musculoskeletal conditions
