Relationship Between Tightness of the Hip Joint and Elbow Pain in Adolescent Baseball Players
Background: Repetitive tensile stresses from valgus torque can induce elbow injury in adolescent baseball players. Insufficient hip range ofmotion (ROM) can change throwingmechanics, reducing the transfer of energy from the lower to the upper extremities. Thus,hip ROM limitations may force the upper extremities to bear the burden of a strong throw. Improper pitching mechanics caused by insufficient hip ROM are thought to increase valgus torque on the elbow when throwing, increasing the risk of elbow injury.
Purpose: To investigate the relationship between elbow pain and hip ROM in adolescent baseball players.
Study Design: Cross-sectional study; Level of evidence, 3.
Methods: A total of 122 adolescent baseball players with a mean age of 12.0 years (range, 6-14 years) participated in this study. Elbow pain, hip flexion angle, and the internal rotation angles of the hip at 0 and 90 of flexion were assessed. Participants were divided into a pain group and a normal group based on the pain assessment, and each hip angle was compared between groups using Student t tests. P values
