Pelvis, lower trunk, and upper trunk sequencing patterns in amateur golfers with lower back pain.

The most commonly injured area for golfers is the lower back. The purpose of this study was to describe the sequencing patterns of the pelvis, lower trunk (LT), and upper trunk (UT) in golfers with lower back pain (LBP). Twelve amateur golfers with a history of LBP performed five driver swings recorded with a motion capture system. The timing of peak segment angular velocity in relation to maximum club velocity was recorded for each golfer. The pelvis and LT reached peak angular velocity significantly before the UT. Limiting separation between the pelvis and LT may be a mechanism that increases stabilization for golfers with LBP.
