Plain English Summary

Background and study aims
Lower back pain (LBP) is a common problem affecting most people during their lifetime. Many people who experience LBP will recover within a few weeks and can manage the pain with painkillers, but for some people the pain turns into a long term condition. In cases of very severe pain, when all other treatments have failed to work, spinal surgery might be recommended. Spinal fusion surgery is a procedure carried out to stabilise the spine and reduce pain. The number of patients who undergo lower back (lumbar) spinal fusion surgery has increased worldwide. Elective spinal surgery often involves a long hospital stay and is not always successful. There is a risk that the surgery might have to be repeated later on, and there is also the risk of developing complications before and after surgery. Also, there are various factors which increase the likelihood of unsuccessful surgery outcomes, such as smoking, severe pain before surgery and a fear of physical movement that might cause pain. Physical activity and exercise are crucial parts of the rehabilitation programme following spinal fusion surgery, and fear of movement is a major problem that prevents recovery. At the moment, there are no set guidelines on how best to prepare patients with severe LBP for spinal fusion surgery. Cognitive behavioural therapy (CBT), a well-known psychological talking therapy, is a frequently used and effective way to treat a range mental health conditions, such as phobias and anxiety. However, CBT has not been tested as an approach to help patients manage fear of pain before spinal fusion surgery. The aim of this study is to see whether a combined physiotherapy and CBT programme (the PREPARE programme) can help patients prepare for surgery, and increase physical activity following surgery more than standard care alone.

Who can participate?
Adult patients from participating trial centres scheduled for spinal fusion surgery.

What does the study involve?
Participants are randomly allocated into one of two groups. Those in group 1 (intervention group) have 4, 1 hour sessions with a CBT-trained physiotherapist and receive a guided exercise plan. Participants are asked to monitor their physical activity before and after surgery. The first physiotherapy session takes place 12 weeks before surgery. Those in group 2 (control group) are given treatment as usual. All participants complete questionnaires. There is a follow up interview 1 week before surgery, then again at 3 and 8 weeks, 3 and 6 months, and lastly 1, 2 and 5 years after surgery. At follow-up participants complete questionnaires and carry out various functional performance tests.

What are the possible benefits and risks of participating?
Participants in the intervention group receive structured preoperative pain management in addition to standard care. There are minimal risks associated with participation in this study. Some participants may experience transient increased pain during treatment.

Where is the study run from?
1. Spine Center (Sweden)
2. Sahlgrenska University Hospital (Sweden)

Study information

Scientific title

PREPARE (PREhabilitation, Physical Activity and ExeRcisE) persons with severe low back pain for an optimal functional outcome after lumbar fusion surgery: a randomised controlled trial



Study hypothesis

1. Patients with severe low back pain (LBP) that get specific guidance in exercises that target the patient’ specific fear of movement and catastrophising thoughts will experience improved functioning, be less depressed, less fearful of movement and be more active postoperatively as compared to patients who get usual care. This will increase patient satisfaction and pain reduction postoperatively, and their level of activity and participation.
2. The intervention (PREPARE) is more cost effective as compared to usual care in terms of direct and indirect health care costs.
3. The patients’ objective level of physical activity and her/his own functioning goal will better predict the outcome of surgery as compared to disability measures. There is a difference between three various measures of physical activity (movement registration, subjective report according to a questionnaire, and the patients reported functioning).

Severe low back pain (disc degenerative disease)


1. Group A (n=55) will receive specific guidance from a physiotherapist on how to stay active despite pain based on cognitive behavioral therapy (CBT) principles.
2. Group B (n=55) will receive treatment as usual (general advice to stay active before surgery, and to make contact with a physical therapy for further guidance).

Drug names

Primary outcome measure

Disability measured by Oswestry Disability Index (ODI).

Secondary outcome measures

1. Patient Specific Function Scale will be used to measure patients' own functioning goal.
2. Physical activity levels (sitting/lying and time spent upright) will be measured by the movement registration system Actigraph (uniaxial accelerometer).
3. The Pain Catastrophising Scale (PCS).
4. Zung Self-Rating Depression Scale (Zung).
5. Functional performance testing: five-minute walking, 50-ft (15 m) fast walking, sit to stand, 1-min stair-climbing.
6. The Swedish version of Tampa Scale of Kinesiophobia (TSK-SV) questionnaire.
7. Self-Efficacy for Exercise (SEE) self-report scale to measure self-efficacy for exercise in nine specific situations.
8. European Quality of Life 5 Dimensions Questionnaire (EuroQol/EQ-5D) (mobility, self-care, usual activity, pain/discomfort and anxiety/depression).
9. Patients’ self-report the effect of treatment (surgery) measured by Global Assessment.
10. The patients perceived harmfulness of daily activities will be measured by Photographs of Daily Activities (PHODA).
11. Cost-effectiveness will be measured by estimating quality of life before and after the treatment (EQ-5D), the number of quality adjusted-life-years (QALY) will be calculated. Days of sick-leave will be collected from the Social Security Office. The days of hospital stay as well as number of health-care consultation will be collected through the patients’ charts in addition to the patient’s own recording.
