Joint and muscle problems in the pelvis and lower back can cause extreme pain in the back and sacroiliac area. Bauerfeind’s SacroLoc braces and supports stabilize and relieve pressure where the pelvis and sacroiliac connect. With its two-part viscoelastic cushion pads, SacroLoc massages massages trigger points around the sacroiliac joints, for soothing pain relief that also stimulates circulation, thus helping the healing process.
