Although reported in manual workers, the condition is most common in athletes who require sustained and excessive use of their upper limbs to perform in their particular sport. The symptoms resolve rapidly after cessation of exercise, only to recur with further exertion.
In the upper limb, CECS typically presents with exercise-induced pain and tightness of the forearm, with occasional paraesthesiae and loss of forearm muscle control. This condition was not recognised as exercised-induced compartment syndrome in the upper limb until 1984, and it is still less well documented compared to CECS in the lower limb. Grip strength decreases statistically significantly following onset of symptoms of CECS of the forearm.Ĭhronic exertional compartment syndrome (CECS) was first described in 1956 in the anterior tibial compartment in a footballer. There is a statistically significant increase in the forearm flexor compartment pressures in elite motorbike racers with CECS, but with marked variability of these values. The mean pre-exercise grip strength decreased post-exercise to, a mean decrease of 14.99 mmHg ( P < 0.0001). The mean pre-exercise forearm compartment pressures significantly increased post-exercise, with a mean increase of 18.80 mmHg ( P < 0.0001). Of the 11 riders recruited to the study, 10 completed the full testing regime. Their grip strength and forearm flexor compartment pressures were measured before and after a set exercise programme.
MethodsĮlite motorbike riders with a clinical diagnosis of CECS of the right forearm when racing were recruited during the opening rounds of a British Superbike season. This study investigated forearm flexor compartment pressure pre- and post-exercise in elite motorbike racers clinically diagnosed with CECS and assessed their grip strength before and after arm pump exercise. Remarkably little research has been published on chronic exertional compartment syndrome (CECS) of the forearm.
