Strand 2001.
| Methods | RCT conducted in Norway | |
| Participants | Patients sick‐listed >8 weeks due to LBP. 117 patients randomised, 61% female, average age 43.6 years, mean duration of pain 10 years | |
| Interventions |
MBR (Multidisciplinary Rehabilitation): 4 weeks, 5 days/week, 6 hours/day. Physical treatment (strengthening, body awareness, aerobic fitness, relaxation), education, CBT (coping, responsibility for Rx, focus away from pain), workplace intervention Usual (Control): usual care in the community, most had physiotherapy, 1/3 have alternative interventions |
|
| Outcomes | Work (% return to work) Follow‐ups: ST (post‐treatment), MT (8 months), LT (1 year) | |
| Notes | Subgroup analyses: High intensity intervention, Low baseline symptom intensity (<60% of maximum scale score) | |
| Risk of bias | ||
| Bias | Authors' judgement | Support for judgement |
| Random sequence generation (selection bias) | Low risk | In Haldorsen 1998. "individuals were allocated at random to one of two groups, the Treatment group or the Control group, by means of a sequence of pre labeled cards contained in sealed envelopes. The allocation sequence was prepared beforehand by a physician" |
| Allocation concealment (selection bias) | Low risk | In Haldorsen 1998. "individuals were allocated at random to one of two groups, the Treatment group or the Control group, by means of a sequence of pre labeled cards contained in sealed envelopes. The allocation sequence was prepared beforehand by a physician" |
| Blinding of participants | High risk | Not possible |
| Blinding of clinicians | High risk | Not possible |
| Blinding of outcome assessment (detection bias) All outcomes | High risk | Not possible; patient reported outcome |
| Incomplete outcome data (attrition bias) All outcomes | High risk | pg.801 Patients. 117/162 randomized patients followed up |
| Intention to treat analysis | Unclear risk | Not stated |
| Selective reporting (reporting bias) | Unclear risk | No protocol |
| Comparability of groups at baseline | Low risk | Table 1. Groups comparable on relevant demographic and clinical variables |
| Compliance | Unclear risk | Not stated |
| Cointerventions | Unclear risk | Not stated |
| Timing of assessment | Low risk | pg.801 Procedure. "The same physiotherapist assessed patients at baseline (before randomization) and at the 1‐year follow‐up" |
