What does SLR positive mean?
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 does straight leg raise test for?
The straight leg raise (SLR) test is the most commonly performed physical test for diagnosis of sciatica and lumbar disc hernia [10]. The SLR is considered positive when it evokes radiating pain along the course of the sciatic nerve and below the knee between 30 and 70 degrees of hip flexion [2].
What is SLR in physiotherapy?
The Straight Leg Raise (SLR) test is a commonly used test to identify an impairment in disc pathology or nerve root irritation. It have also specific importance in detecting disc herniation and neural compression.
What is lower limb tension test?
Lower limb tension tests (LLTT), also known as neural tension tests, are used to evaluates the length and mobility of the components of the nervous system.
What is a Waddell test?
The purpose of the Waddell test is to identify patients with low back pain who may require a more detailed psychological assessment; not to identify exaggerators. Factors such as the patient’s anxiety and the examiners bias can also lead to skewed Waddell results.
What are SLR tests with a particular nerve bias?
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. SLR test and its Modifications
What happens during an SLR test?
(Interesting fact: The SLR primarily puts a stretch on the L5-S1 nerve root segment). It should be noted that a painful, stretching, or other neurological symptom may be produced by this test as a result of neural tension due to adhesions while travelling throughout the body.
What happens to the sciatic nerve during SLR?
During SLR these nerve roots are pushed anteriorly and inferiorly pulling the duramater is pulled caudally, laterally and anteriorly. Tension in the sciatic nerve occurs in a sequence as it pulls the sciatic foramen, then the sacrum and then the nerves that cross over the pedicles and finally the intervertebral foramen.
How to treat neural tension?
How to Treat Neural Tension. A similar technique often confused with nerve gliding is nerve sliding. Nerve sliding works by elongating the nerve bed at one joint, while simultaneously shortening it at another (Coppieters & Butler, 2008). The reasoning is that the nerve can move without increasing strain.
