Hypothesis – This study is designed to evaluate the results of using the Orthotrac Pneumatic Vest versus an EZ form brace in patients with radiating leg pain from disc bulge / protrusion / herniation. Specifically, our hypothesis is that patients given the Orthotrac Pneumatic Vest (OPV) will have greater pain relief and increased self-reported functionality and fewer progressions to surgery than those using the EZ form brace.
