Slipped disc is a misnomer. Most often it is a dehydrated disc that begins to bulge like a tire that is low on air. Just like a tire low on air when the car turns the tire can move sideways on the rim. If such a sideways motion is detected between your vertebra the muscles may be triggered to clamp down on it to stop the motion which if sustained make the problem worse. So will traction help? Usually yes. The fluid that hydrates and inflates the disc to its full height has to be sucked out of the bone above and below it. This normally happens by bending and twisting but traction makes it easier and bending and twisting under traction or laying down is more effective. Inversion tables or using an exercise to move the spine while laying down are effective means of traction.
Yes,Physiotherapists usually apply traction. The idea is to pull on the lower half of the body to gently stretch the spine. If you have traction, you lie flat on your back. The physiotherapist holds onto your legs and pulls them to a stretched position for a few seconds at a time. Another way to do traction is with a system of weights and cables. They are attached with a harness and can apply traction for a longer period of time.More details visit painrelief.sg.
