Case report: reduction of low back pain in a professional golfer.

Previous research agrees that the majority of injuries that affect male golfers are located in the lower back and that they are related to improper swing mechanics and/or the repetitive nature of the swing. This study describes the trunk motion and paraspinal muscle activity during the swing of a golfer with related low back pain (LBP) and assesses the effect of a 3-month period of muscle conditioning and coaching on these variables. Motion of the trunk was measured using three-dimensional video analysis and electromyograms (EMGs) were recorded from the same six sites of the erector spinae at the start and end of the 3-month period. At the end of the period, the golfer was able to play and practice without LBP. Coaching resulted in an increase in the range of hip turn and a decrease in the amount of shoulder turn, which occurred during the swing. In addition, a reduction in the amount of trunk flexion/lateral flexion during the downswing occurred in conjunction with less activity in the left erector spinae. These changes may serve to reduce the torsional and compressive loads acting on the thoracic and lumbar spine, which in turn may have contributed to the cessation of the LBP and would reduce the risk of reoccurrence in the future. In conclusion, further research with more subjects would now be warranted in order to test the findings of this program for the prevention of low back in golfers as piloted in this case report.
