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.
以往的研究一致认为，影响男性高尔夫球手的大多数损伤位于下背部，且与挥杆动作力学不当和/或挥杆动作的重复性有关。本研究描述了一名患有相关下背痛（LBP）的高尔夫球手在挥杆过程中的躯干运动和椎旁肌活动，并评估了为期3个月的肌肉训练和指导对这些变量的影响。使用三维视频分析测量躯干运动，并在3个月训练期开始和结束时，从竖脊肌的相同六个部位记录肌电图（EMG）。在训练期结束时，该高尔夫球手能够在无下背痛的情况下打球和练习。指导导致在挥杆过程中髋部转动范围增加，肩部转动量减少。此外，在下挥杆过程中躯干前屈/侧屈量减少，同时左侧竖脊肌的活动也减少。这些变化可能有助于减少作用于胸腰椎的扭转和压缩负荷，这反过来可能有助于下背痛的缓解，并降低未来复发的风险。总之，为了验证本项目在预防高尔夫球手下背痛方面的研究结果（如本病例报告中所试行的），现在有必要对更多受试者进行进一步研究。
