What is normal SLR?

What is normal SLR?

Ideally, normative SLR range of motion in healthy, asymptomatic individuals could be used for comparisons to testing in clinical populations. Unfortunately, when used as a neurodynamic test, normal SLR range of motion is highly variable, averaging from 40° to 85° [1,3,6,9].

How reliable is the straight leg raise test?

The interrater reliability of the active straight leg raise test (κ = 0.53; 95% CI: 0.20, 0.84) and lumbar extension load test (κ = 0.47; 95% CI: 0.14, 0.78) was moderate.

What is the normal range of motion for straight leg raise?

Table 1. No significant differences in ranges measured were found. Our measurements for ranges of straight-leg raising were 30° to 90° before spine flexion and 50° to 90° or more including spine flexion (Table 1).

What does a positive straight leg raise test usually indicate?

A positive straight leg raising test (also known as Lasegue sign) results from gluteal or leg pain by passive straight leg flexion with the knee in extension, and it may correlate with nerve root irritation and possible entrapment with decreased nerve excursion.

What is considered a positive straight leg raise?

The test is positive when raising the leg between 30 to 70 degrees causes pain to occur and radiate down the leg to at least below the knee, and often all the way down to the great toe (sensitivity 91%, specificity 26%). Sensitivity may improve with dorsi-flexion of the foot while the leg is elevated.

What does the active straight leg raise test?

The active straight leg raise test (ASLR) is a loading test which is used to assess pain provocation and the ability to load the pelvis through the limb. It is performed in lying and the patient is instructed to lift the leg 20cm off the bed (Mens, et al., 2001).

What constitutes a positive straight leg raise?

“The straight leg raise test is positive if pain in the sciatic distribution is produced between 30 and 70 degrees passive flexion of the straight leg.”.

What is a normal straight leg raise degree?

Average: 60-80 degrees. Poor: Less than 60 degrees. Description: The active straight leg raise is a measure of range of motion at the hamstring that can actively be used during movement. While many runners may feel like their hamstrings are tight after a run, in reality, they may have adequate range of motion.

What does a positive response to a straight leg?

How to Interpret the Straight Leg Raise Test? A positive result happens when pain radiates down the leg to at least below the knee when your afflicted leg is raised between 30 degrees to 70 degrees. Many times, patients feel pain all the way down to the big toe.

Why is the active straight leg raise?

The straight leg raise is also used by doctors and physical therapists to assess lumbar spine impingement, herniated discs, and sciatic pain . It can help differentiate injuries of the hip from that of the lumbar spine . You need no special equipment to do a straight leg raise other than space where you can lie on your back freely.
