Correlation Coefficients: Statistics that quantitatively describe the strength and direction of a relationship between two variables. The patient asked to score impairment on a sixpoint scale:4. Altered motor control strategies in subjects with sacroiliac joint pain during the active straight-leg-raise test. A., Cripps, J., Graf, F., Lin, I.

Adding compression over the lumbar spine. To compress the hip joints use the same handling but place your hands over the greater trochanters. (2001). Assess the stability of the lumbar spine and pelvic girdle (coxa and sacrum and associated joints - sacroiliac and pubic symphysis joints). Our mission is to improve the lives of patients and providers by creating the most impactful educational content on an innovative learning platform. Journal of manipulative and physiological therapeutics, 30(4), 270-278.

Hip flexion will cause a forward pull on the innominate, which was previously thought to be counteracted by the contralateral bicep femoris and ipsilateral lateral abdominals, to press the innominate towards the sacrum for increased force closure.

Purpose of Test: To test for the presence of a disc herniation. The Straight Leg Raise (SLR) test is a neurodynamic test. The straight leg raise, also called Lasègue's sign, Lasègue test or Lazarević's sign, is a test done during a physical examination to determine whether a patient with low back pain has an underlying herniated disc, often located at L5 (fifth lumbar spinal nerve). Understanding the Active Straight Leg Raise (ASLR): An electromyographic study in healthy subjects.Manual therapy, 17(6), 531-537.Laslett, M., Aprill, C. N., McDonald, B., & Young, S. B. European Spine Journal, 20(5), 759-765.Hu, H., Meijer, O. G., Hodges, P. W., Bruijn, S. M., Strijers, R. L., Nanayakkara, P. W., ... & van Dieën, J. H. (2012). B., ... & Avery, A. The authors did conclude that further research is required to understand the reliability/validity of these tests in a low back pain patient population. Straight Leg Raise Test. The test is performed after the verbal instruction:3. (2002). The Active Straight Leg Raise (ASLR) is one of the fundamental tests of the Functional Movement Screen (FMS) that is a lower limb reciprocal pattern that assesses dynamic hip mobility while simultaneously looking at core stability and motor control of the trunk and pelvis during single leg hip hinging. Is the psoas a hip flexor in the active straight leg raise?. Validity of the active straight leg raise test for measuring disease severity in patients with posterior pelvic pain after pregnancy. The results indicated that:In 2011 Hu and colleagues investigate the role of psoas in hip flexion using the ASLR test. A disruption of the quadriceps tendon, patella, or patellar tendon can lead to the inability to perform a straight leg raise. As for many clinical tests we have available, this one provides us with valuable information about load transfer and the ability to augment load transfer, but should be considered with other physical asterisk signs to determine the overall treatment path for the patient. Spine, 26(10), 1167-1171.Mens, J. M., Vleeming, A., Snijders, C. J., Koes, B. W., & Stam, H. J. Some of the more common modulations which I use are shown below. In this case the load of the entire lower extremity is placed on the lower lumbar spine and pelvis. It is usually stated that passive SLR test assesses only sprains, and that active SLR test assesses both sprains and strains. The test is performed with the patient in a supine position with legs straight and feet 20cm apart.2. This image shows pushing up through the contralateral shoulder to bias the ipsilateral internal oblique and contralateral external oblique. Active Straight Leg Raise Test Purpose: Assess the stability of the lumbar spine and pelvic girdle (coxa and sacrum and associated joints - sacroiliac and pubic symphysis joints). © 2020 MedBridge Inc. All rights reserved. Adding compression to the posterior pelvic ring. They performed a cross-sectional study to understand the internal validity of the ASLR test and Trendelenburg test. +LR = Positive Likelihood Ratio Straight Leg Raise Flexibility Test . Hu, H., Meijer, O. G., van Dieën, J. H., Hodges, P. W., Bruijn, S. M., Strijers, R. L., ... & Xia, C. (2011).

During the test you can also look at the contribution of the hip to the overall movement (by palpating the femoral head).

Below are a few ways in which you can modulate the ASLR test.

There is so much more information that can be gained about the loading strategies patients adopt. However, this is a bit of an oversimplification. In a study conducted by Hu et al (2012), sixteen healthy nulliparous females performed the ASLR in three different environments; normal, with an ankle weight, and with a belt, and the muscle activity of the abductor muscles, rectus femoris (ispilateral) and biceps femoris (contralateral) were observed. The scores of both sides are added, so that the summed score ranges from 0 to 10.Sn = 0.76 for all patients (Higher Sn when just looking at patients with severe symptoms)Reliability between group 1 week apart: ICC = 0.83
