Brain Imaging Study on Biomarkers for Chronic Back Pain
This study aims to understand why some treatments work well for people with long-lasting back pain, while others don't. Researchers believe that a person's individual make-up, including factors like their brain activity, genetic background, and even their social and psychological experiences, could affect how they respond to painkillers. The goal is to find specific indicators, or 'biomarkers', that can help doctors predict which treatments will be most effective for each person. This could lead to more personalised and successful ways of managing chronic back pain, helping individuals get the right treatment for them.
At a glance
What is this study about?
Imagine you have long-lasting back pain, and your doctor prescribes medication. For some people, it helps a lot, but for others, it doesn't seem to make much difference. This study wants to find out why this happens. Researchers believe that the way your body and mind are put together, including things like your brain's unique patterns, your genes, and even your personal thoughts and feelings, might play a big part in how well a pain treatment works for you.
The main idea is to discover special 'clues' or 'indicators' – which scientists call biomarkers – within your body. These clues could help doctors understand your pain better and predict which specific treatments or strategies would be most effective for you. Instead of a one-size-fits-all approach, this could lead to more tailored care, meaning your treatment plan is designed specifically for your individual needs.
To do this, the study will compare people with chronic back pain to healthy volunteers. They will look at various aspects of each person, including brain activity, psychological factors, and genetic information. Some participants with back pain might also receive a dummy pill (a placebo) that looks like a real painkiller, while others will just be monitored. By carefully studying all this information, the researchers hope to find those important biomarkers that can improve how doctors treat chronic back pain in the future.
Key takeaways
- Aims to understand why pain treatments work differently for individuals.
- Looks at brain, genes, and personal experiences for clues.
- Hopes to find 'biomarkers' for more personalised pain treatment.
- Involves MRI scans, questionnaires, and possibly genetic samples.
- Compares people with chronic back pain to healthy volunteers.
- Participation could help improve future pain management for many.
Who may be eligible?
This study is looking for two main groups of people: adults aged 18 to 75 who have long-lasting back pain, and healthy adults within the same age group. Everyone taking part needs to be right-handed and comfortable understanding and completing tasks and questionnaires in English.
For those with long-lasting back pain, you would need to have been experiencing low back pain for at least six months, as confirmed by your doctor. Your pain levels during the two weeks before joining should also be at least a 4 out of 10 on a simple scale.
There are also reasons why some people *cannot* take part. These include having certain heart, lung, or nerve conditions that could make participating unsafe. You also cannot join if you have anything inside your body or other conditions (like severe claustrophobia or being pregnant) that would prevent you from having an MRI scan, which is a type of body scan. Healthy participants should not be experiencing any acute or chronic pain.
Could this study suit you?
Answer these quick questions to see if you may be eligible. This is a guide only — the research team makes the final call.
- Are you between 18 and 75 years old?
- Are you right-handed?
- Are you comfortable reading and writing in English?
- Do you have low back pain that has lasted for more than 6 months (if applying for the chronic pain group)?
- Are you generally healthy with no severe heart, lung, or nerve conditions that would make an MRI scan unsafe?
- Do you have no metal implants or other reasons that would prevent you from having an MRI scan?
What does participation involve?
If you decide to take part in this study, you would first provide some personal information and likely complete several tasks and questionnaires that look at your thinking, feelings, and beliefs about treatment. You would also have an MRI scan, which uses magnets and radio waves to create detailed pictures of your brain. Genetic samples, likely from saliva or blood, will also be collected. Your participation will involve attending several experimental sessions. For some participants with chronic back pain, after these initial sessions, you might receive a mock drug (a placebo) that looks like a real pain medicine. Other chronic back pain participants will simply continue to provide information about their pain without receiving a mock drug. The total duration of your participation will depend on the specific path you take in the study, but it involves multiple data collection points.

Common questions
What is 'chronic back pain'?
Chronic back pain means you've had pain in your lower back for six months or longer.
What is an MRI scan?
An MRI scan uses strong magnets and radio waves to create detailed pictures inside your body, like your brain. It's safe and doesn't use X-rays.
What is a 'biomarker'?
A biomarker is a special signal or clue in your body, like a unique brain pattern or genetic information, that can help doctors understand your health or predict how you'll respond to treatment.
Will I get any specific treatment in this study?
The study is mainly for research. Some back pain participants might receive a dummy pill (placebo) to see how expectations affect pain, but it's not a new treatment.
Can I leave the study if I change my mind?
Yes, you are free to leave the study at any time without giving a reason, and it won't affect your regular medical care.
