Description of intervention(s) / exposure
Pragmatic randomised controlled trial with 172 subjects randomised to two treatment groups (i) motor control exercise (ii) graded activity. Both treatments will consist of 12 one hour treatments over an 8 week period, ie: 2 sessions/week in the first month and 1 session/week in the second month and 2 additional 1 hour follow-up sessions at 4 & 10 months. Patients will be advised to do home exercises, consistent with the exercise approach they are receiving. The total time for home exercises will sum to at least 1/2 hour/week in the first month and 1 hr/week in the second month. The treatment sessions and home exercises will add up to at least 20 hours of treatment.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects seeking treatment for their low back pain will be approached by medical practitioners and physiotherapists. If the subject demonstrates interest in participating in the study the recruiting primary care practitioner will contact the investigators who will screen the subjects for eligibility criteria and obtain consent. Randomisation will be performed at the first treatment session by the physiotherapist. Numbered, sealed, opaque envelopes will be used to conceal the patient's group allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The allocation schedule will be generated using the random number function in Excel. We will generate a sequence with random permuted blocks.
Masking / blinding

Summary
Brief summary
About 1 in 10 Australians have persisting or chronic low back pain. Most are managed in primary care and the most frequently prescribed treatment is exercise. Chronic low back pain remains a major health problem because not all patients respond to each treatment so on average treatment effects are small. At present there are no guidelines to help clinicians select the best treatment for a patient. As a result, time and money is wasted on treatments which ultimately fail to help the patient.

Our proposed study is a direct comparison of the two most promising types of exercise approaches used in Australia: a graded activity program where patients perform an individualised, whole body exercise program, and a motor control program, where patients perform a series of specific spinal stabilisation exercises. This study will compare the effects of these two interventions. We will also identify patient features that may predict a patient's response to treatment. Prediction features used will be clinical/demographic data, measures of beliefs and attitudes about pain, measures of physical activity and fitness, measures of control and co-ordination of the lumbar spine and pelvis.
