Today I welcome Elisabetta Brigo who is a Physiotherapist from northern Italy. Elisabetta has recently started her PhD in Rehabilitation Sciences at Hasselt University in Belgium. We discuss why you can't prevent back pain by avoiding so called 'incorrect postures', why there is no such thing as 'correct' or 'perfect' posture, why there is no spinal curvature that is strongly associated with pain, why we should not be afraid of butt wink and much more. FYI: the use of smartphones is poorly correlated with neck pain and disability! Elisabetta didn't hear that question correctly.
