Purpose: to examine the relationship between the lumbar lordotic curve and
hamstring muscle tightness in adults.
Methods: In this study, lumbar curve angle was measured by bubble
inclinometer, and Hamstrings muscles tightness was measured with a
standard goniometer (using active knee extension test technique), in 40
males (17) and females (23) subjects with mean age of 39 years not
complaining from structural abnormalities of the spine or knee region.
Results: this study found that there was a non-significant correlation between
lumbar lordotic angle and hamstring muscle tightness (spearman correlation
coefficient (rho)=0.2, P value=0.12).
Conclusion: lumbar lordotic angle not significantly correlates with hamstring
muscle tightness. This may underestimate the importance of hamstring
muscle stretching exercises in treating patients complaining with mechanical
low back pain
