A prevention program that improves physical function was effective in the prevention of medial elbow injury in youth baseball players, according to a recently published study.

Researchers identified 305 youth baseball players who did not have a history of elbow and shoulder pain. One hundred thirty-six players underwent the Yokohama Baseball-9 program, which included nine stretching and strengthening exercises, and 169 players were placed in the control group. Investigators performed a clinical assessment of the elbow and shoulder joint, an ultrasonography assessment of the elbow and a physical function assessment. The incidence of medial elbow injury was the primary endpoint for efficacy. Other outcomes included absolute measures of physical function and change in these outcomes after 1 year.

Results showed players who participated in the intervention program had a significantly lower rate of medial elbow injury compared with controls. Investigators noted improvements in the intervention group regarding total range of motion of the shoulder rotation, hip internal rotation, shoulder internal rotation deficit, lower trapezius muscle strength and the thoracic kyphosis angle. Predictive factors of a lower rate of medial elbow injury included increased total shoulder rotation, increased hip internal rotation of the nondominant side and decreased thoracic kyphosis angle. – by Monica Jaramillo
