![]() Keywords: forearm compartment syndrome chronic exertional compartment syndrome CECS exercise MRI forearm pain compartment syndrome athletes.Ĭhronic exertional compartment syndrome (CECS) of the forearm is a rare entity with the first case only being described in 1983. Furthermore, SIR may be used to accurately diagnose CECS of the forearm. The extensor carpi radialis, flexor digitorum profundus and flexor digitorum superficialis muscles were most commonly involved.ĬONCLUSION: This study confirms that significant SI changes are apparent in patients with CECS of the forearm when making use of a standardised pre- and post-exercise MRI protocol. After post:pre-exercise comparisons, a statistically significant difference was found between control and patient groups ( p = 0.0010). RESULTS: A total of 86 SIs were measured (43 pre- and 43 post-exercise) in nine study participants (five patients and four controls). Signal intensities were evaluated pre- and post-exercise in involved muscle groups and ratios were calculated. A specific, reproducible pre- and post-exercise MRI scanning protocol was utilised in both patient and control subjects between 20. METHOD: The study retrospectively examined MRI scans of patients treated for CECS of the forearm and compared these to the MRI scans of asymptomatic high-level rowers. ![]() Also, to objectively measure MRI SIs within muscle compartments when using a pre- and post-exercise regime and calculating a signal intensity ratio (SIR) between post- and pre-exercise studies. OBJECTIVES: To assess and quantify signal intensity (SI) changes of involved muscles in patients with CECS of the forearm compared to healthy control subjects competing in similar sporting disciplines. The diagnosis remains challenging due to the absence of objective, reproducible diagnostic studies.
