Sensorimotor cortical activity in acute low back pain: a cross-sectional study

Sensorimotor cortical activity is altered in both the immediate acute, and chronic stages of musculoskeletal pain. However, these changes are opposite, with decreased cortical activity reported in experimentally-induced acute pain (lasting minutes to hours), and increased cortical activity in chronic, clinical pain (lasting>6 months). It is unknown whether sensorimotor cortical activity is altered in acute, clinical musculoskeletal pain (lastin
