BACKGROUND: We sought to analyze whether the amount of @entity528 correlates with a @entity1 's physical fitness, and to determine if these findings on lumbar magnetic resonance imaging (MRI) scans can help predict functional outcomes. METHODS: A retrospective review was performed on 172 @entity1 . Inclusion criteria involved being seen by a spine surgeon for low back @entity158 , having aerobic index (AI), body mass index (BMI), @entity717 index (ODI), and body fat percentage measured recently, and having had a recent lumbar MRI scan. The percentage of fatty @entity121 was graded by three reviewers using T2-weighted axial images at @entity69294 using a newly proposed system that was validated independently. The system is graded as follows: Grade 1: 0-24%, Grade 2: 25-49%, Grade 3: 50-74%, and Grade 4: 75-100%. An independent t-test was used for comparisons. RESULTS: The average AI was 34.87, and the cohort was divided into two groups: above-average AI (89 @entity1 ) and below-average AI (83 @entity1 ). For all paraspinal fat measurements and body fat percentage, the difference between the above- and below-average AI groups was statistically significant (P < 0.05), with the least amount of @entity528 and body fat in the greater AI group. Weight alone and BMI were not found to be significantly different between those with above-average AI when compared to those with below-average AI (P = 0.491 and P = 0.122, respectively). There was a trend for lower ODI scores in the above-average AI group (41.9 vs 46.1), but this did not reach statistical significance between the two groups (P = 0.075). For all @entity1 it was shown that there was significantly less paraspinal fat at the L3 level as compared to L5 (P < 0.001). CONCLUSIONS: We were able to show that @entity1 with a higher AI have lower body fat percentages and lower amounts of @entity528 in their lumbar paraspinal musculature. The amount of @entity528 , therefore, correlates with physical fitness. @entity1 with higher AI also showed a trend toward having a lower ODI score.

Does lumbar paraspinal muscle XXXX correlate with aerobic index and @entity717 index?
