Lumbosacral MRI, of a 57-year-old man with 5 years history of LBP without sciatica, BMI = 18, there is disc bulge at L4/5 and L5/S1 levels. No neural canal stenosis. Average VAS score = 5. Axial cuts revealed grade 0 MS degeneration at L3/4 level, grade 2 MS degeneration at L4/5 and L5/S1 levels, MS = 4. MS = 1.154 + (0.017*Age) + (0.184* duration years) + (0.081* Sciatica) + (0.287* VAS). According to MS equation, the expected MS = 4.5
