Chronic Exertional Compartment Syndrome (CECS) is a debilitating disorder that causes lower extremity pain most commonly in active populations. It is thought to arise from increased pressure in muscle compartments (commonly lower extremity anterior and lateral) leading to pain, paresthesia and an inability to tolerate exercise. The cause of CECS is unknown but is likely a combination of muscular, neurologic and vascular contributions. Current standard treatment is surgical fasciotomy, but it is only successful in 66% of patients. Many have complications and/or need repeat procedures. Efficacy is even worse in military members at 55%. Other alternative strategies have emerged such as botulinumtoxin A injections (BoNT-A) and gait retraining, but data is limited.

The objective of this study is to simultaneously assess the effectiveness of non-surgical treatments, BoNT-A injections and Supervised Gait Retraining (SGR), in terms of lower pain control and ability to return to full duty among adult active-duty service members suffering from lower extremity CECS, specifically of the anterior and/or lateral compartments.
