Association between Non Dominant Hip and Dominant Shoulder Internal Rotation Range of Motion and Shoulder Injury in Cricket Fast Bowlers: A Cross-Sectional Study

Abstract

Background: The overhead throwing motion is complex, and restrictions in range of motion (ROM) at the hip may place additional demands on the shoulder that lead to injury. However, the relationship between hip and shoulder ROM in fast bowlers with and without a history of shoulder injury is unknown. Aim: To find out the association between non dominant hip and dominant shoulder internal rotation range of motion with and without shoulder injury in cricket fast bowlers. Study design: A cross-sectional study. Method: 35symptomatic and 35 asymptomatic fast bowlers were included. Symptomatic and asymptomatic fast bowlers were screened for the measurement of non-dominant hip and dominant shoulder rotation range of motion. And SPADI used to screen for the shoulder injury in symptomatic fast bowlers. Results: There is significant association between shoulder injury and non-dominant hip IR ROM and no significant association between non-dominant hip and dominant shoulder IR ROM. Conclusion: Fast bowlers with shoulder injury had decreased non dominant hip IR ROM and the co-relation was significant. The decreased IR ROM was compensated by other kinematic chain and ER ROM. Hence, fast bowlers with shoulder pathology must always be screened for hip joint ROM as well.
