Purpose :The study provides a basis for Spinal Stabilization excercises and Physiotherapy.Aging leads to atrophy of Muscle Mass and  can be replaced by connective tissues such as fat,which is called Sacropenia,Which occurs with aging.

 Methodology :The study is a prospective study. The study population includes all patients with lower backache who underwent MRI.

The patient were divided into two groups :

-Patients with severe spinal pathologies (Degenerative Spondylolisthesis,Disc prolapse,Disc Extrusion)

-Patients without severe spinal pathologies.

In the MRI images,Cross Sectional areas of Multifidus And Erector Spinae We measured by manually tracing the fascial boundaries If the Muscles.

Qualitative measurements of the muscles were obtained between Muscle (low signal) and fast tissue (high signal).

The Functional Cross sectional area(FCSA) : Cross section area ratio &

MF CSA: ES CSA ratio will be calculated and compared between the two groups by using an independent t-test.

Conclusions :

•The  study provides a basis for spinal stabilization exercise and physiotherapy.

•               The MultiFidus muscle is an important stabilizer of the lumbar spine neutral zone, and atrophy of the muscle decreases the ability to control the neutral zone and is strongly associated with Lower Back Pain .

•               Spinal stabilization has been observed to be more effective over time in treating lower back pain than minimal intervention and exercise therapy alone. Therefore, the treatment focus has shifted to reactivation and strengthening of the smaller muscles of the spine to improve long-term stabilization of the vertebral column .
