Lumbar belts focus on replacing or taking place of the muscles. They are designed to increase pressure in the abdomen cavity in order to take stress off the disc but studies have shown this does not actually occur. Lumbar belts should also be worn only with limited use. The Serola Sacroiliac Belt is designed to take place of the ligaments, allowing normal function for the muscles because they are no longer being forced to contract to stabilize the joint and ligaments. Taking the pressure off of the SI Joint results in pain reduction, effectively stronger muscles, better circulation and can be worn all day with no negative effects.
