The Association Between Femoral Nerve Tension and Hip Flexor Length

Background: Femoral nerve tension and hip flexor muscle length are critical factors in musculoskeletal health. Their relationship is particularly important in diagnosing and managing conditions like low back pain, often associated with tight hip flexors.Objective: This study aimed to explore the association between femoral nerve tension and hip flexor muscle length in individuals with acute low back pain compared to healthy controls.Methods: A correlational study was conducted with 68 participants (34 healthy controls and 34 acute low back pain patients). Data were collected using self-administered questionnaires and clinical tests, including the Prone Knee Bend Test and Modified Thomas Test. Femoral nerve tension and hip flexor length were measured using a goniometer. Data were analyzed using Pearson correlation and linear regression in SPSS version 25.Results: The Thomas Test showed a statistically significant negative correlation between femoral nerve tension and hip flexor length in Group B (-0.096, p=0.042). In the Prone Knee Bend Test, a minimal positive correlation was observed (0.007, p>0.05). Cross-tabulation highlighted a significant association between test results in the control group (p=0.025).Conclusion: A significant relationship exists between femoral nerve tension and hip flexor length in individuals with acute low back pain. These findings suggest the need for targeted interventions focusing on neural and muscular components.
