Passive hip rotation range of motion in LPGA golfers.
In healthy adult subjects, joint range of motion (ROM) has been shown to be relatively symmetrical (3, 5, 6, 8, 13, 27). For example, it would be expected that the amount of hip internal rotation (IR) on the left side would be equal to the amount of IR on the right side. Participation in sports places specific demands on the musculoskeletal system that may cause modifications in soft-tissue over time. Some of the demands imposed by some sports are applied to the body in an asymmetrical fashion, which may influence the pattern of soft-tissue modification. For example, athletes who participate in sports requiring repetitive unilateral rot
