There is no question that low back pain is a problem for many people. Annually, low back pain accounts for
approximately 40% of all lost workdays and has been estimated to cost $49
billion within the industrial sector.1
So what do we do about it?
Attempts to identify effective interventions for patients with low back pain (LBP) have been largely unsuccessful.2,3 One explanation offered for the lack of evidence is the inability to define subgroups of patients most likely to respond to a particular intervention.4 Recently, Flynn et al. validated a clinical prediction rule that identifies a subgroup of patients with nonspecific low back who are likely to respond to spinal manipulation.5
The predictor variables, based on the history and physical examination, were identified as follows:
- Pain of less than 16 days duration
- No symptoms distal to the knee
- One or both hips with internal rotation < 35°
- One or more hypomobile lumbar segments
- FABQ*-work subscale score of < 19
The presence of four out of five
variables in the prediction rule increases the likelihood of success with
manipulation from 45% to 95%.
According to a study by Childs et al.6, patients who were “positive on the rule” (met 4 or 5 of 5 predictor variables) and did not receive spinal manipulation were 8 times more likely to experience a worsening in disability as compared to those that did.
