The purpose of this study is to define the reliability and accuracy of Near Infrared Spectroscopy (NIRS) in the detection of intra-compartmental tissue perfusion in injured and noninjured extremities over time. The investigators hypothesize that this technology, combined with vital signs, intracompartmental pressures and clinical examinations, will be useful in diagnosing acute compartment syndrome (ACS), monitoring patients at risk for ACS, and evaluating the adequacy of fasciotomy in patients treated for ACS.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| Stable controls | Uninjured soldiers to provide normative data for stable physiological status |
| |
| Critical controls | Critically injured soldiers with no lower extremity traumatic injuries (excepting skin abrasions and small/superficial fragmentation wounds) to provide normative data for the "shock" physiological status. |
| |
| Lower extremity trauma | Soldiers with severe traumatic lower extremity injuries in stable and shock physiologic status. This is the investigational cohort. |
