Quizplus · Accepted Answer

The most common back injury is strain on the lumbar muscle group,which includes the muscles around the lumbar vertebrae.Injury to these areas affects the ability to bend forward,backward,and side to side.This also decreases the ability to rotate the hips and lower back.The cervical response is incorrect because it refers to the neck region of the back.The thoracic response is incorrect because it refers to the rib/chest area of the back which has decreased movement.The trapezius is incorrect because it refers to a muscle in the back over the scapula.
