Corticomotor depression is associated with higher pain severity in the transition to sustained pain: a longitudinal exploratory study of individual differences

The organisation and function of the primary motor cortex is altered in the acute,6 transitional28 and chronic stages of musculoskeletal pain and in chronic pain populations, altered motor cortex plasticity is associated with pain severity and impaired function.29,30,40 These findings suggest that aberrant motor cortex plasticity may contribute to the development of chronic pain. However, direct evidence for a relationship between an individual's motor plasticity in response to pain and symptom severity is lacking.
