Chronic back pain is often a difficult condition to treat. Which option is best suited?
A review by the US ‘Agency for Healthcare Research and Quality’ (AHRQ) focused on non-invasive nonpharmacological treatments for chronic pain. The following therapies were considered:
- mind-body practices,
- psychological therapies,
- multidisciplinary rehabilitation,
- mindfulness practices,
- manual therapies,
- physical modalities,
Here, I want to share with you the essence of the assessment of spinal manipulation:
- Spinal manipulation was associated with slightly greater effects than sham manipulation, usual care, an attention control, or a placebo intervention in short-term function (3 trials, pooled SMD -0.34, 95% CI -0.63 to -0.05, I2=61%) and intermediate-term function (3 trials, pooled SMD -0.40, 95% CI -0.69 to -0.11, I2=76%) (strength of evidence was low)
- There was no evidence of differences between spinal manipulation versus sham manipulation, usual care, an attention control or a placebo intervention in short-term pain (3 trials, pooled difference -0.20 on a 0 to 10 scale, 95% CI -0.66 to 0.26, I2=58%), but manipulation was associated with slightly greater effects than controls on intermediate-term pain (3 trials, pooled difference -0.64, 95% CI -0.92 to -0.36, I2=0%) (strength of evidence was low for short term, moderate for intermediate term).
This seems to confirm what I have been saying for a long time: the benefit of spinal manipulation for chronic back pain is close to zero. This means that the hallmark therapy of chiropractors for the one condition they treat more often than any other is next to useless.
But which other treatments should patients suffering from this frequent and often agonising problem employ? Perhaps the most interesting point of the AHRQ review is that none of the assessed nonpharmacological treatments are supported by much better evidence for efficacy than spinal manipulation. The only two therapies that seem to be even worse are traction and ultrasound (both are often used by chiropractors). It follows, I think, that for chronic low back pain, we simply do not have a truly effective nonpharmacological therapy and consulting a chiropractor for it does make little sense.
What else can we conclude from these depressing data? I believe, the most rational, ethical and progressive conclusion is to go for those treatments that are associated with the least risks and the lowest costs. This would make exercise the prime contender. But it would definitely exclude spinal manipulation, I am afraid.
And this beautifully concurs with the advice I recently derived from the recent Lancet papers: walk (slowly and cautiously) to the office of your preferred therapist, have a little rest there (say hello to the staff perhaps) and then walk straight back home.
