Plain English Summary

Background and study aims
Chronic or persistent pain is pain that carries on for longer than 12 weeks despite medication or treatment. Most people get back to normal after pain following an injury or operation. But sometimes the pain carries on for longer or comes on without any history of an injury or operation.
Evidence shows that increasing physical activity can be one of the best things to help manage chronic pain. However, people who suffer from chronic pain are often very inactive. The reasons for this may be quite different from one person to the next. We would like to find out what stops people in pain from being active and what we could do to support them to do more. Eventually, we would like to develop a plan that can be tailored to individual people who are suffering from pain, to help them stay active

Who can participate?
Adults over the age of 18 referred by the NHS Tayside pain service. Must have experienced pain for at least 6 months

What does the study involve?
Participants are asked to join this study after being referred to the pain service and consenting to take part in the research. Participants must be assessed by the pain service as having moderate to severe pain. Participants will be asked to attend two appointments about a week apart, due to social distancing rules this is most likely to take place remotely, for example, video call. The first appointment will include fitting an activity monitor, filling in a questionnaire and a semi-structured interview. At the 2nd appointment, participants will fill in a second questionnaire and remove the activity monitor. In between the two appointments the activity monitor will track participants activity.

What are the possible benefits and risks of participating?
Taking part in the study may not immediately benefit those taking part. However, we hope that the results of the trial will help us manage activity in people who suffer from pain in the future. We anticipate no major disadvantages of taking part. There is a very low risk that participants may develop a skin reaction to the waterproof dressing used to attach the activity monitor to their thigh. If this should happen we would ask participants to remove the tracker and contact the research team.

Where is the study run from?

Increasing physical activity and exercise in chronic pain patients


Up to 45 people referred to the Tayside pain service will be invited to take part in the study, aiming for a total of 40 completing the first study visit. They will take part in a semi-structured interview designed to assess their perceptions of the barriers and facilitators to their participation in PA. In addition, participants will be asked to complete 7 validated self-report questionnaires to collect information about their pain severity, and its impact, as well as attitudes to physical activity. Demographic and basic clinical information including age, gender, height and weight will be collected together with underlying diagnosis, other co-morbidities, and postcode to enable Scottish index of multiple deprivation to be recorded. Participants will then be provided with an activPAL4TM activity monitor ( and asked to wear this for 1 week. 20 participants who consent to wearing a Fitbit monitor will be asked to wear a Fitbit Charge 3 ( monitor in addition to the activPAL monitor. Both the activPAL and FitBit trackers are CE marked. Participants will be contacted after 1 week and will then be asked to complete the 7 questionnaires as before as well as acceptability and feasibility questions on the activity monitors

Half the participants will receive an Activpal only and the other arm will receive an Activpal and Fitbit, all participants will wear the activity monitors for one week between appointment 1 and 2. After appointment 2 when the activity monitors are removed there is no follow up. Allocation to receive a Fitbit is based on willingness to wear one and availability (i.e. not random).
