Lasegue’s test is also popularly known SLRT (Straight Leg Rise Test) because the methodology of the test involves raising the subject’s leg straight to arrive at conclusions. However, it must be remembered and acknowledged that the Lasegue test has many variations involving various methodologies and different probable conclusions or confirmations.
This test has been named after Ernest Charles Lasegue who was a French physician of repute and experience. In the late nineteenth century, he described the test and associated the leg rising with pain in the lower back.
However, Lasegue’s version of the test is not normally used by modern practitioners of medicine. The version of the tests that are used by modern medical practitioners was actually described and widely used by Laza Lazarevic. In many parts of the world the entire test along with its variations is known by the Lazarevic Sign or Lazarevic Tests in memory of Laza Lazarevic. Laza Lazarevic was a well known and reputed physician from Serbia.
Whatever be the name, the purpose of these tests is to ascertain or adjudge the presence of a herniated disk in patients who are suffering from pain in the lower portions of their back. The traditional test is performed by asking the patient to lie down on a platform with his face towards the. The person on whom the test is to be done is then required to ensure that his upper body and torso are straight and placed on the platform.
Thereafter the patient’s leg is raised while ensuring that the patient’s knee remains unbent and straight. The test is conclusive of a herniated disk if the patient feels pain during the leg raising procedure at a point where the angle of the raised leg is between 30 and 70 degrees. Depending upon the angle of the leg raise where the patients start feeling sciatic pain various other conclusions regarding disorders and diseases can be drawn by experienced medical practitioners.
There are variations of this the Lasegue’s test where the patient is required to perform similar leg raise with the doctor or examiner lifting the leg while the patient is sitting in an upright position over a platform.
Understanding of the Braggard Test and its probable confirmations is also needed by any examiner or orthopedic medical practitioner to conclude specifically the outcomes of the Lasegue’s test. The most important role that the Braggard Test can play in the overall scheme of things relevant to the Laegue’s Test and the sign determines the reality of the pain. This means that the Braggard Test may be used to ensure whether the pain experienced by any patient is genuinely indicative of a herniated disk or whether there are other reasons that are causing the pain.
It can be safely said that the Braggard test is a crucial adjectival test for specifying and guaranteeing the outcome and result of the Lasegue Test. Reverse Lasegue Test is also among the popular and widely used variations of the Lasegue test by orthopedic medical practitioners across the world.
