Plain English summary of protocol
Background and study aims
Back pain is a common problem that affects most people at some point in their life. It most commonly affects the lower back (Low Back Pain [LBP]). Counselling has been found to be effective at reducing pain, improving physical function and reducing the duration of sick leave for LBP patients. We wish to evaluate the possible long-term effects of the counselling during a 6-year follow-up period.
Who can participate?
LBP patients aged 17-63 who expressed concerns about their ability to maintain their current job.
What does the study involve?
Patients are randomly allocated to receive either usual care (a brief instruction in exercise) or the counselling intervention. The counselling intervention consists of counselling by an occupational physician, a workplace visit if needed, a 6-week interview and a follow-up interview after 3 months by the occupational physician.
What are the possible benefits and risks of participating?
Participants will benefit from a counselling session (occupational physician or usual care). The study follows the rules of using register data in Denmark, where it is a requirement that the participants in a study are protected and not recognisable. We are not aware of any risks involved in participating in the study.

| Scientific title | Vocational prognosis of participants in a randomised trial addressing counselling of low back patients in secondary healthcare - a 6 years follow-up study |
| Study acronym | VAL-300 |
| Study objectives | Low back worries, experienced work place barriers and general level of physical activity influence disability defined as level of sick leave, function and pain 3 months after the intervention start. Added 19/01/2016: The original randomised study found a statistical and clinical relevant effect on low back pain and function after 3 months in the intervention group. The research question in the actual trial is to investigate the long term effect on vocational prognosis during a 6 years follow up in the intervention group compared to the control group. |
