The knowledge of the onset and cessation timing of the paraspinal muscles that surround the lumbar spine is an important area of research for the understanding of low back pain. This study examined the timing of the erector spinae and external oblique muscle activity in a group of golfers with and without low back pain. The study compared the results of surface electromyography measurements for two groups of golfers. Twelve male golfers who had reported a mild or greater level of pain in the lower back that was experienced while playing golf were examined. A further fifteen male golfers who had reported no history of lower back pain in the previous 12 months were recruited as controls. The results showed that the low-back-pain golfers switched on their erector spinae muscle significantly in advance of the start of the backswing. This finding was not evident in the group who did not have low back pain symptoms. Low-back-pain golfers, therefore, may use the erector spinae muscle as a primary spinal stabiliser instead of the stronger deeper muscles such as transversus abdominis and multifidus. These results may have important implications for conditioning programmes for golfers with low back pain.
了解围绕腰椎的椎旁肌的起始和停止时间，对于理解下背痛来说是一个重要的研究领域。本研究调查了一组有和没有下背痛的高尔夫球手中竖脊肌和腹外斜肌的活动时间。该研究比较了两组高尔夫球手的表面肌电图测量结果。对12名报告在打高尔夫球时经历过轻度或更严重程度下背痛的男性高尔夫球手进行了检查。另外招募了15名在过去12个月中没有下背痛病史的男性高尔夫球手作为对照组。结果显示，有下背痛的高尔夫球手在回杆开始之前就显著激活了他们的竖脊肌。这一发现在没有下背痛症状的组中并不明显。因此，有下背痛的高尔夫球手可能将竖脊肌用作主要的脊柱稳定肌，而不是使用更强壮的深层肌肉，如腹横肌和多裂肌。这些结果可能对有下背痛的高尔夫球手的训练计划具有重要意义。
