In recent years there has been an explosion of interest in the role of the brain in spinal disorders. Indeed, there is now a signifiant body of research investigating the topics of sensorimotor integration, balance and proprioception abnormalities, and central sensitisation. All of this is helping us to understand that patients with persistent or recurrent spinal problems are most likely expressing symptoms of spinal instability. In other words, they either lack sufficient sensory acuity to accurately perceive spinal motion, or have developed abnormal motor patterns to regulate movement and alignment (particularly when under load). The end result of this is a tendency to uncontrolled movement and ultimately pain.
All this new knowledge is important and directly applicable to chiropractic practice. After all, spinal manipulation could be seen as a novel sensory stimulus to alter such deficits of sensorimotor control. But what other questions remain about the brain, and how might they help us to conceive better methods of applying treatment? One person who is looking at the bigger picture of brain science is Daniel Wolpert, who spoke at the TEDGlobal Conference in 2011 about why we even have brains at all. His talk is quite enlightening.
According to Wolpert, we have not evolved brains to think with. Rather, they are there ‘to produce adaptable and complex movements’. Wolpert describes himself as a ‘movement chauvinist’ as he sees it as the fundamental function of the brain. Watch his video below, then ponder how a chiropractic approach to restoring functional movement might impact a person’s brain and wellbeing. Something to think about...
