Overuse injuries in baseball—particularly in the shoulder and elbow—are a significant problem at both amateur and professional levels. Studies have shown that shoulder pain is one of the most common complaints among amateur baseball players, with a prevalence ranging from 13.4% to 20.6% of players. Elbow injuries are also very common and affect from about a fifth to a quarter of all players, with youth players at greater risk. While all position players can develop upper-extremity injuries, these injuries tend to occur more frequently and severely in the dominant arm of pitchers.
Despite advancements in medical management and increased knowledge about preventive care, the rates of shoulder and elbow injuries in baseball players are on the rise. The consequences of these injuries can be significant, leading to time lost from the sport, reduced performance, the need for surgical interventions, and giving up the sport entirely.
Researchers have identified several potential risk factors for shoulder and elbow injuries in baseball players including increased mechanical load (measured by pitch count or training hours), higher pitching velocity, and decreased shoulder range of motion (ROM), particularly in flexion, internal rotation, and horizontal adduction. While the perceived stress of throwing curve balls is thought to increase the risk for arm injury, it’s not currently demonstrated in the data that this is the case. There’s limited evidence that weakness of the shoulder abductors and external rotators can contribute to shoulder pain, as can scapular dysfunction. Despite the clinical emphasis on the role of lower limb and trunk function in injury prevention and rehabilitation, there isn’t much research to support this strategy.
A study that included 60 active young adult baseball players may have uncovered a strategy for preventing upper extremity injuries. In the study, researchers assigned half the players to a stretching group and the other half to a stretching plus manual therapy group with the goal of addressing range of motion deficits between their dominant and non-dominant sides. After a single treatment session, both groups demonstrated improved range of motion (internal rotation, total arc of motion, and horizontal adduction), but the stretching plus manual therapy group experienced greater improvement. Because the loss of motion is a known risk factor for arm-related injuries, the authors reported that this combined approach should be used to prevent future injury.
Chiropractors utilize manual therapies more than any other healthcare profession with goal of breaking up scar tissue and adhesions, promoting circulation to the region to facilitate healing and strengthening of muscles and tendons, and restore normal motion to affected joints.
