No Sound?  If you’re playing a video and the sound isn’t working, it may be because the sound is off. When playing a video from a desktop computer, you will see a series of vertical bars at the bottom right corner of the video. When the vertical bars are blue, it means the sound is on (see image 1 below). If the vertical bars are grey, it means the sound is off (see image 2). To turn on the sound of a video, click on each vertical grey bar until all the bars become blue. On smaller devices such as a tablet or a phone, simply increase the volume of the device to be able to hear a video.

Straight Leg Raise Test

The Straight Leg Raise test, which is commonly abbreviated as the SLR test, is designed to detect radicular leg pain in the symptomatic limb. This test is also called the Straight Leg Raising Test and the Laségue’s Sign or the Laségue’s Test.

With the patient in the supine position, slowly raise the symptomatic limb while maintaining knee extension and ask the patient to indicate if lower limb symptoms are reproduced or exacerbated. 

This test is considered positive if it reproduces or exacerbates sciatic pain or other symptoms of radiculopathy.

To confirm sciatic involvement, lower the limb to the point where the pain is relieved and ask the patient to bring the chin to the chest. If this reproduces the patient’s lower limb pain, it confirms sciatic radiculopathy.

Another way to confirm sciatic involvement is to ask the patient to lower the head back down and then dorsiflex the ankle. If this reproduces the patient’s leg symptoms, it helps confirm sciatic radiculopathy. This procedure is sometimes called Bragard’s test.
