Effects of Pain on Lumbar Spine Movement and Muscle Activity Patterns

Results in reorganization of muscle representation in the motor cortex. (correct)

Leads to differential activation of individual muscles through cortical stimulation.

Increases muscle activation in all individual muscles through cortical stimulation.

Enhances fine motor control between synergistically linked trunk muscles.

Decreased proportion of fast-twitch type-II glycolytic fibres.

Increased proportion of Type 1 slow-twitch fibres.

Increased proportion of fast-twitch type-II glycolytic fibres. (correct)

No changes in muscle fibre type.

No effect on cortical motor drive or movement patterns.

Leads to increased Type 1 slow-twitch muscle fibres.

Reflects the collective role of changes in cortical motor drive, muscle tissue, and movement patterns. (correct)

Does not reflect changes in muscle tissue.
