Objectives: To determine the correlation of low back pain with Straight leg raising test.

Study Design: Observational study.

Study Settings & Participants: This research was performed at the different hospitals of Karachi i.e Ziauddin Hospital and IPRS, LUMHS, Jamshoro, Pakistan. Sample of 384 patients were calculated through open Epi with a point prevalence 18.1% at 95% confidence level and margin of error is 0.05.

Outcome measures: The study enrolled 384 patients at outpatient department of physiotherapy at Ziauddin Hospital. These patients reported with a history of low back pain, which included acute, sub-acute and chronic low back pain. Bilateral sacroiliac joint assessment and SLR test were done. SLR was measured through goniometry.

Results: Total 384 patients were enrolled in this research of which 218 (56.6%) were male and 166 (43.1%) were female. The FABER and Trendelenburg test were measured and results showed that 26.2 % FABER test was positive in these patients. A Pearson product-moment correlation was run to calculate the relationship between low back pain with straight leg raising test. There was a negative correlation between low back pain and straight leg raising test, which was statistically significant (r = -0.297n = 384, p< .000).

Conclusions: The SLR test shows Substantial arbitration and negative correlation in low back pain. When it is being explained in this way might also be applicable test for neural tissue hypersensitivity.

Key Words: Low back pain, SLR, VAS scale, FABER test, goniometry
