The microcapillary infusion method was evaluated in recording intramuscular pressure during isometric and concentric exercise of the erector spinae muscle. Intramuscular pressure at rest was 6.1 (SD = 1.4) mm Hg without infusion and 8.3 with an infusion rate of 1.5 ml/hour. When the subject experienced muscle fatigue during exercise, the muscle relaxation pressure had increased to 14 mm Hg. The erector spinae muscle was found to be heavily loaded during exercise with an average muscle contraction pressure of 175 mm Hg. Recording of intramuscular pressure in the erector spinae muscle during exercise tests can be an additional method in the study of ergonomics and biomechanics of the spine as well as in the diagnosis of chronic compartment syndrome in this muscle.
在竖脊肌等长收缩和向心收缩运动期间，对微毛细管输注法记录肌内压力进行了评估。静息时，未输注情况下肌内压力为6.1（标准差 = 1.4）毫米汞柱，输注速率为1.5毫升/小时时为8.3毫米汞柱。当受试者在运动中出现肌肉疲劳时，肌肉放松压力增加到14毫米汞柱。发现在运动期间竖脊肌承受较大负荷，平均肌肉收缩压力为175毫米汞柱。在运动测试期间记录竖脊肌的肌内压力，可作为脊柱人体工程学和生物力学研究以及该肌肉慢性骨筋膜室综合征诊断的一种辅助方法。
