Due to the lifestyle features or other disorders lumbar multifidus muscle (LMM) might weaken and lead to low back pain (LBP) symptoms. Through imaging techniques this atrophy can be denoted as severe, slight and none or no atrophy at all. Most cases of atrophy are visible in individuals with LBP and with signs of accumulation of fat around these muscles. In many cases such fat accumulation occurs after a low back surgery. After a back injury one might suffer from LBP along with leg pain due to a condition known as "dorsal ramus syndrome". Here the impulses sent by adjoining joint muscles and LMM might not reach the spine area due to injury. This might result in a very severe back pain besides disc and neural disorders.

Carrying out an elaborate and advanced MRI imaging of the multifidus of lumbar can detect the level of damage to tissues and also measure fatty replacement. Cases of reflexive inhibition have been noted to cause atrophy of LMM to some extent. The myotomes of the LMM are connected by a spinal segment also connecting many other joints. Any form of atrophy of multifidus always leads to low back pain symptoms. Such multifidus atrophy prevents voluntary activation of LMM. This in turn prevents the natural working of muscles around the spine area and leads to spinal area disorders. In case of muscle atrophy there is reduction in the level of voluntary contraction of muscles of the multifidus. This reduces the ability to perform isometric contractions of multifidus muscles. So, any form of muscle dystrophy needs to be mended and rectified at the earliest to avoid a reoccurrence. This will in turn relieve us of the traumatic conditions of suffering from long painful lower back pain hours and help us lead normal and healthy lives.
