What does a negative straight leg raise test mean?
A negative test suggests a likely different cause for back pain. [citation needed] A positive straight leg test reproduces radiating leg pain. If it only causes back pain, then the test is negative. Because this is often misunderstood, it is prudent to add a statement of clarification.

What does a positive straight leg raise test mean?
If you have pain down the back of your leg below the knee when your affected leg is raised, the test is positive (abnormal). It means that one or more of the nerve roots leading to your sciatic nerve may be compressed or irritated.
What does a positive straight leg test feel like?
A positive test elicits pain in the leg, buttock, or back at 60 degrees or less of leg elevation. The pain is typically worsened by dorsiflexion of the ankle or neck flexion, and it is relieved with flexion of the knee and hip. A positive straight leg raise test usually indicates S1 or L5 root irritation.
What is negative straight leg raise?
A negative straight leg raise test (i.e., no pain radiating down the leg with the test maneuver), may indicate that your pain is not due to a significant herniation, however it is only one of several potentially useful pieces of information.
How can I test myself for sciatica?
Slump TestSit upright in a chair without back support.Clasp your hands behind your back.Slump forward and bring your neck down, touching your chin to your chest.Extend one leg forward and flex your foot towards your shin.Repeat with the other leg.
What is the normal range of motion for a straight leg raise?
SLR neurodynamic testing range of motion is highly variable, ranging from approximately 15° to over 90° with a moderate association with multiple demographic characteristics, such as sex, weight, BMI and activity level.
What does SLR negative mean?
A negative test suggests a likely different cause for back pain. A positive straight leg test reproduces radiating leg pain. If it only causes back pain, then the test is negative.
How do you do straight leg raises?
Bend the knee of your non-injured leg at a 90-degree angle, planting the foot flatly on the floor. Stabilize the muscles on your straight leg by contracting your quadriceps (the group of muscles on the front of your thigh). Inhaling slowly, lift the straight leg six inches off the ground. Hold for three seconds.
What is a positive leg raise?
Furthermore, a positive straight leg raise test is determined when pain is elicited by lower limb flexion at an angle lower than 45 degrees. During the test, if the pain is reproduced during the leg straightening, patients usually request that the examiner aborts the maneuver and by flexing the patient’s knee, the buttock pain is usually ...
What is a straight leg raise test?
The straight leg raise test, also called the Lasegue test, is a fundamental maneuver during the physical examination of a patient with lower back pain. It aims to assess for lumbosacral nerve root irritation. This test can be positive in a variety of conditions, though lumbar disc herniation is the most common.
How did Lazarevic describe the straight leg raise test?
Lazarevic described the straight-leg-raising test by explaining sciatic pain by stretching the sciatic nerve based on his experience with six patients. Based on this misinterpretation of the original description, it is recommended to describe the maneuver as the straight leg raise test. Indications.
What is a positive cross straight test?
A positive test is when the patient reports pain in the involved limb at 40 degrees of hip flexion with the uninvolved limb. A crossed straight test is positive in central disc herniation in cases of severe nerve root irritation. [13] Clinical Significance.
What causes a straight leg raise?
Other causes of a positive straight leg raise test include facet joint cysts or hypertrophy. This activity describes the pathophysiology of low back pain and highlights the role of the interprofessional team in the management of patients with a positive straight leg raise test. Objectives:
Who was the first person to perform a straight leg raise?
Nevertheless, it is believed that a Serbian neurologist, Dr. Lazar Lazarevic, [12] was the first who documented the straight leg raise test as it is known today in the article named “Ischiac postica cotunnii”, initially published in the Serbian Archives of Medicine (1880), and republished in Vienna (1884). Dr.
What is the Lasegue test?
The Lasegue test is basically a provocation test that evidences radicular irritation in the lumbosacral region by lower limb flexion and can be due to multiple causes. Radicular symptoms are primarily produced by nerve root inflammation by surrounded structures.[9]
What is a straight leg raise?
The straight leg raise is a passive test. Each leg is tested individually with the normal leg being tested first. When performing the SLR test, the patient is positioned in supine without a pillow under his/her head, the hip medially rotated and adducted, and the knee extended.
What is a modified leg raise test?
Modifications to the Straight Leg Raise test can be used to stress different peripheral nerves to a greater degree; these are referred to as SLR tests with a particular nerve bias.
What is the SLR test for ankle dorsiflexion?
Inclusion of ankle dorsiflexion in the SLR is documented as Lasegue's test or Bragard's test. Inclusion of great toe extension in the SLR (instead of ankle dorsiflexion) is documented as Sicard's Test.
How does a clinician lift a patient's leg?
The clinician lifts the patient's leg by the posterior ankle while keeping the knee in a fully extended position. The clinician continues to lift the patient's leg by flexing at the hip until the patient complains of pain or tightness in the back or back of the leg.
Does a positive lumbar disc test increase specificity?
Combining positive test results increased the specificity of physical tests, but few studies presented data on test combinations. The authors of the meta analysis conclude that When used in isolation, current evidence indicates poor diagnostic performance of most physical tests used to identify lumbar disc herniation.
What is a straight leg raise?
A straight leg raise is used to place tension on the sciatic nerve to aid in diagnosis of the presence of nerve root compression of the lower lumbar nerve roots (L4-S1) (see Fig. 17-4, A ). The patient is prone and the lower extremity is raised by the clinician to the maximum tolerable level of hip flexion range of motion (ROM). The test must be performed passively and the patient's knee maintained in full extension and the hip in neutral rotation. The opposite leg is kept in extension. For each test, the clinician notes any symptoms produced during the test and also the degree of hip flexion at which the symptoms are produced. A positive test result requires reproduction of the patient's familiar leg symptoms between 30° and 70° of hip flexion. It is important to distinguish between reproduction of familiar symptoms and hamstring tightness.
What is a positive contralateral straight leg raise?
Both the symptomatic and contralateral lower extremities are examined. A positive contralateral straight leg raise test result occurs when a straight leg raise of the asymptomatic lower extremity reproduces the symptoms in the symptomatic extremity.
What is a passive leg raise test?
Passive straight leg raise testing is the most commonly used test for lumbar discopathy and nerve root irritation. The patient lies supine while the therapist passively raises the patient's leg. Reproduction of low back pain with radiating pain to the posterior thigh noted before 60 degrees of elevation is associated with disk protrusion. Back pain with motion past 70 degrees is typically associated with the sacroiliac or lumbar spine joints because this range of motion causes negligible further nerve root deformation. 4,20–23
What is the opposite leg of a test?
The opposite leg is kept in extension. For each test, the clinician notes any symptoms produced during the test and also the degree of hip flexion at which the symptoms are produced. A positive test result requires reproduction of the patient's familiar leg symptoms between 30° and 70° of hip flexion.
What is an ASLR test?
The active straight leg raise test (ASLR) examines the ability of the patient to transfer load through the pelvis in supine lying and has been validated for reliability, sensitivity, and specificity for pelvic girdle pain (Mens et al 1999, 2001, 2002 ). It can also be used to identify nonoptimal stabilization strategies for load transfer through the pelvis in the supine position. The supine patient is asked to lift the extended leg 20 cm and to note any effort difference between the left and right leg (does one leg seem heavier or harder to lift). This is not a test for pain and the patient should only score the effort. The strategy used to stabilize the lumbopelvic region during this task is observed ( Fig. 40.4 ). The leg should flex at the hip joint and the pelvis should not rotate, sidebend, flex, or extend relative to the lumbar spine. The rib cage should not draw in excessively (overactivation of the external oblique muscles), nor should the lower ribs flare out excessively (overactivation of the internal oblique muscles), nor should the abdomen bulge (breath holding – Valsalva). The pelvis is then compressed passively and the ASLR is repeated; any change in effort is noted. The location of the compression can be varied (anterior, posterior, oblique) to determine where more compression (force closure) is needed for optimal load transfer ( Fig. 40.5) ( Lee 2004 ).
