Overview

Cross-sectional study examines MRI-based classification and directional preference in lumbar disc herniation, suggesting significant associations.

Key Points

To explore the relationship between MRI-based classification of lumbar disc herniation and directional preference identified through mechanical diagnosis and therapy.
Cross-sectional study with 120 individuals suffering from low back pain and confirmed lumbar disc herniation.
Collected demographic data, MRI findings, and performed mechanical diagnosis and therapy to assess directional preference.
Analyzed the association between disc type and directional preference using Pearson’s chi-square test.
Protrusion was the most prevalent disc type observed in 54.17% of participants.
Extension directional preference was identified in 49.16% of cases.
A significant association between disc type and directional preference was found (p < 0.001), with a strong effect size (Cramér’s V = 0.51).
