Pain education and exercise are interventions known to assist recovery of function in patients with musculoskeletal pain.6,37 However, it still remains unknown how to target the well-established sensorimotor changes occurring in response to acute or chronic muscle pain.45 Acute experimental muscle pain reduces corticomotor excitability35,46,59 and a body of evidence suggest that patients with chronic musculoskeletal pain show a reduction in corticomotor representation of the muscles in pain.57,67 Indeed, persistent pain can alter our movement patterns and may serve to protect the painful limb against further harm31 and as result lead to long-standing, possibly maladaptive, changes in cortical motor excitability.
