Page 1: Participant Information

This participant information is for chiropractic patients who wish to participate in research on long-term pain


The title of our research project is:

”Prevalence of central sensitization in chiropractic patients presenting with chronic musculoskeletal pain.”

Principal Investigator: Karl Martin Stålaker

Associated University: AECC University College, Bournemouth


I am Karl Martin Stålaker, a chiropractor working in Saxilby, UK. As part of my postgraduate Master’s degree that I am currently completing with AECC University College (Bournemouth, UK), I am doing research on pain. Here you can find information and invitation to be part of this research, but you do not have to decide today whether to participate. Before you decide, feel free to talk to anyone you feel comfortable with about it. There may be some words that you do not understand. Please ask me or your own chiropractor to explain, and please ask any questions you might have.


Purpose of the research

In some patients with long-term pain, changes occur in the pain centres within the brain, possibly because the transmission of pain signals is not being properly controlled. The aim of this research is to determine how many chiropractic patients with long-term pain are likely to have such altered pain centre function. It is very important that chiropractors and other medical professionals learn more about the possibility of altered pain centre function, so that they can treat chronic pain patients more effectively.


Type of Research Intervention

This research will involve an online questionnaire that will take you approximately 10-15 minutes to complete.


Participant selection

We are inviting adults who have recently consulted a chiropractor for the first time. We are seeking participants with pain in the neck, shoulder, head, back, hip or pelvis that has been ongoing for at least three months. If you have ever had a stroke, cancer, spinal cord injury or certain neurological diseases (e.g., dementia, Alzheimer’s, Parkinson’s), you will unfortunately not be able to participate.


Voluntary Participation

Your participation in this research is entirely voluntary. It is your choice whether to participate or not, but once submitted, the questionnaire cannot be withdrawn.


Procedures and Protocol

If you decide that you would like to participate in this research study, simply click 'next' at the bottom of this page. If you do not wish to participate, just close your browser window.

The first part of the survey records some basic information about you, such as your age, height, weight, your education, how much you are working, where your pain is and when it started. The second part of the survey asks you questions about other symptoms that sometimes occur at the same time in patients with long-term pain.


Side Effects and Risks

There are no side effects or risks involved in this research. As with all research involving online surveys, there is always the slight possibility that the online survey tool is targeted by internet hackers, which could potentially threaten the confidentiality of your answers. However, since the online survey does not ask for your name, address or date of birth, it would be almost impossible for anybody trying to steal personal information to link your survey answers to you.



You will not receive any payment for participating in our study.



All the information that we collect from this research study will be stored in a password protected secure server at the chiropractic clinic. The data will be anonymous; none of the data we collect for the purpose of this study includes your name, date of birth or address. Nobody but the researcher will be able to access the data. This will ensure that your privacy and confidentiality is maintained according to the GDPR. The results of this study will be used in the researcher’s Master’s dissertation and may later be published in a scientific journal.


Right to Refuse or Withdraw

You do not have to take part in this research if you do not wish to do so. It is your choice, and all your rights will still be respected. You are also free to withdraw from the study after you have opened the online survey. All you need to do is not complete the full survey and simply close your browser window. Once submitted, the questionnaire cannot be withdrawn.


Who to Contact

If you have any questions, you may ask them now or later, even after the study has started. If you wish to ask questions, you may contact:

I have read the abovementioned information. I have had the opportunity to ask questions about it and any questions that I have asked have been answered to my satisfaction.  By continuing with this survey and submitting my answers to the survey questions online, I consent voluntarily to participate in this research.
