What is the threshold for compartment pressure one minute after exercise in chronic exertional compartment syndrome?

In the context of chronic exertional compartment syndrome (CECS), the threshold for diagnosing the condition is significantly important, particularly in relation to post-exercise compartment pressures. Generally, a pressure of 30 mmHg measured one minute after exercise is recognized as a critical threshold that may indicate the presence of CECS.

Chronic exertional compartment syndrome typically presents in the lower leg, and after exertion, the muscle compartments can experience elevated pressures due to increased blood flow and muscle swelling. If the pressure exceeds 30 mmHg, it can lead to compromised blood flow and resultant ischemic symptoms, which align with the clinical presentation associated with CECS.

In clinical practice, measurements of compartment pressure following exercise are utilized to help confirm the diagnosis. Values lower than 30 mmHg post-exercise—such as 10 mmHg, 15 mmHg, or even 20 mmHg—do not typically indicate the same level of concern for compartment syndrome, as they tend to fall within normal ranges for some muscle compartments. This makes the threshold of 30 mmHg a specific marker used to differentiate between those experiencing normal post-exercise recovery and those who may need further intervention due to compartment syndrome.
