Description

This study will examine the effect of blood flow restriction (BFR) training in patients with lower extremity fractures. Patients with tibial shaft fractures will be assigned to either the BFR group or control group. The BFR group will perform exercises with a blood flow restriction device, which occludes venous blood flow in the limb, while performing strengthening exercises as directed by a Doctor of Physical Therapy. The control group will perform the exercises without the device, as is current standard practice in physical therapy. Blood flow restriction training has been shown to prevent strength loss and muscle atrophy after surgery or injury, and studies suggest that it increases biomarkers of bone metabolism and tissue healing. The goal of this study is to examine the use of BFR in trauma patients using a defined protocol, and compare fracture healing, muscle strength, muscle girth, and subjective physical function between groups.
