前交叉韧带术后患者肌肉等长收缩合并乏氏动作时对血压影响

摘要

Objective To investigate the effect of blood pressure change of the isometric contraction combined with Valsalva action for patients after anterior cruciate ligament(ACL)surgery.Methods A retrospective study was performed on 15 patients who were admitted and underwent ACL surgery from November 2016 to March 2017.Patients were required to perform two groups of motion of the quadriceps on Cybex machine,the blood pressure of the two groups of patients were compared after the motions such as isometric contraction and isometric contraction combined with Valsalva action.Results The systolic pressure and diastolic pressure had statistically significant difference between the two groups(P<0.05).In each group,the systolic pressue,diastrolic pressure after motion had statistically significant difference comparing with the peace status(P<0.05).Conclusion The isometric contraction combine with Valsalva action has significant effect than single isometric contraction on blood pressure,Valsalva action should be avoided during training.%目的 探讨肌肉等长收缩合并乏氏动作时对血压变化的影响.方法 选择2016年11月至2017年3月南京大学医学院附属鼓楼医院收治的15例前交叉韧带(ACL)术后患者为研究对象.要求患者在Cybex机上分别做股四头肌极量等长收缩运动和股四头肌极量等长收缩合并乏氏动作两组运动,比较两组运动后患者的血压变化情况.结果 两组运动后,患者的收缩压、舒张压比较,差异均有统计学意义(P<0.05).每组运动后,收缩压、舒张压与平静状态下比较,差异也均有统计学意义(P<0.05).结论 肌肉等长收缩合并乏氏动作比单纯的肌肉等长收缩对血压有显著性影响,在训练时应尽量避免乏氏动作.
