Abstract

Left-right differential erector spinae (ES) muscle strengthening is required to correct ES muscle imbalances. The objective was to test the effect of 6 body positions on the differential activation of the ES muscles. In 14 able-bodied young women, using a surface electromyography system, the bilateral ES muscles activity at the third lumbar (ESL3) and the 10th (EST10) and 6th (EST6) thoracic vertebral levels was measured with the contralateral arm and leg lifted in the prone and quadruped conditions and with a single arm lifted in the quadruped position. Results showed that the activity of the ESL3 was symmetrical (P > .05) and significantly smaller than that of the thoracic ES muscles in all body positions (P < .01). The EST10 and EST6 were differentially activated in all tests (P < .001). Besides, the differential activation was higher in the contralateral-arm and -leg lift in the quadruped position than in the other positions. In conclusion, contralateral-arm and -leg lift and single-arm lift in the quadruped and prone positions are capable of differentially activating the ES muscles on one side more than the other side. Further studies are recommended to examine the effectiveness of these exercises on the correction of ES muscle imbalances in clinical populations.

俯卧位和四足位的左右差异竖脊肌激活。

左-右差立脊肌(ES)需要加强纠正ES肌肉失衡。目的是测试6种体位对ES肌肉不同激活的影响。在14名身体健全的年轻女性中，使用体表肌电图系统，在俯卧和四足姿势下，对侧手臂和腿抬起，单臂四足姿势时，测量了双侧第三腰椎(ESL3)、第10节(EST10)和第6节(EST6)胸椎椎体水平的ES肌肉活动。结果显示，大鼠ESL3肌在各体位的活动均呈对称性(P > 0.05)，且明显小于胸肌(P < 0.01)。EST10和EST6在所有试验中均有差异活化(P < 0.001)。此外，四足体位对侧臂和腿举的差异激活高于其他体位。总之，在四足和俯卧姿势下，对侧手臂和腿的提升和单臂提升能够不同地激活一侧的ES肌肉。建议进一步的研究来检验这些运动对纠正临床人群ES肌失衡的有效性。

期刊介绍： The mission of the Journal of Applied Biomechanics (JAB) is to disseminate the highest quality peer-reviewed studies that utilize biomechanical strategies to advance the study of human movement. Areas of interest include clinical biomechanics, gait and posture mechanics, musculoskeletal and neuromuscular biomechanics, sport mechanics, and biomechanical modeling. Studies of sport performance that explicitly generalize to broader activities, contribute substantially to fundamental understanding of human motion, or are in a sport that enjoys wide participation, are welcome. Also within the scope of JAB are studies using biomechanical strategies to investigate the structure, control, function, and state (health and disease) of animals.
