This is wrong on both counts.
If a chiropractor, osteopath or physiotherapist intervenes to manipulate the spine, some temporary relief may be achieved but the evidence is that the bony structures are relatively unchanged after these procedures. This strongly suggests that any reduction in pain results from other factors like lowered muscle tone, reduced fear and anxiety and the expectation of improvement.
Similarly, surgery to “correct” spinal deviations presumed to be associated with back pain is rarely attempted or required. When it is, the results are seldom better in the medium to longer term than non-surgical interventions like exercise.
It is tempting to see back pain as resulting from some structural defect or imbalance. But our bodies are wonderfully adaptable and robust and it is far more likely that mechanical factors are only part of the story. We’ll look at these other factors next time.
