Pars interarticularis stress lesions in the lumbar spine of cricket fast bowlers.

abstract：BACKGROUND:Tendinopathies are painful overuse injuries observed in athletes participating in jumping sports. These injuries are heavily dependent on the resulting strain from the applied mechanical load. Therefore, mechanisms to reduce tendon strain may represent a primary prevention strategy to reduce the incidence of...
