Analysis of pelvic motion during gait with bivalve brace

Materials and methods 2 asymptomatic adults, with similar physical feature. They wear a thoracolumbar bivalve brace, made with the same protocol (using CAD CAM) for reproducibility. We design the braces according to the principles of the brace immobilization: a good grip on the waist and overall tightening supports on the abdomen, thorax and lumbar. We use the gait analysis system Vicon. To use this system, we make holes in the brace at the location of the markers. Each person walks 6-8 trials in the gait analysis system with and without the brace.
