However, these positions can have significant impacts on the patient’s physiological functions. This article overviews the historical background of Trendelenburg position and reverse Trendelenbury position, their effects on various physiological functions, recent advancements in their clinical applications, and strategies for preventing and managing associated complications.展开更多

Present conservative rehabilitation focus is on lumbo-pelvic hip stability exercises in individual planes. However, a functional integrative rehabilitative approach addressing lumbo-pelvic misalignment in the sagittal (anteriorly tilted pelvis) and frontal (Trendelenburg gait) planes has not been presented. The aforementioned patho-biomechanical conditions and their management are often discussed estranged from each other rather than functionally integrated. This paper serves as a short communication which discusses the lumbo-pelvic anatomy, identifies the anatomical and biomechanical associations between the anteriorly tilted pelvic and Trendelenburg gait. Through an analysis of relevant literature, recommendations were made on the improvement of flexibility of the hip flexors, taut iliofemoral and pubofemoral ligaments to resolve the primary abnormal force-couple, with improved flexibility of the erector spinae and quadratus lumborum to resolve the secondary abnormal force-couple. In addition, improved flexibility of the hip flexors should coincide with closed-kinetic chain concentric strengthening of the ipsi-lateral hip abductors and contralateral external obliques. Patient education is also needed for self-re-alignment of the lower extremity to a neutral position and neutral foot stance. Biokineticists/exercise therapists should also review the patient’s gait biomechanics to determine whether sartorius synergistic dominance is in play. In conclusion, the association between an anteriorly tilted pelvis and Trendelenburg gait, is in regard to taut anterior acetabulofemoral ligaments and femoral retroversion torsion angle that is both preceded and followed by the biomechanical influence of various anatomical structures. These anatomical and biomechanical factors must be evaluated by the biokineticists/exercise therapists before prescribing a rehabilitative programme to ensure successful rehabilitati展开更多
目的:观察妇科腹腔镜手术CO2气腹合并体位改变对心脏电生理的影响。方法:选择择期行妇科腹腔镜手术的患者30例,全身麻醉,气腹压12 mm Hg,头低位15°。记录并分析麻醉前(T0)、麻醉后(T1)、气腹后1 min(T2)、气腹头低位后30 min(T3)...目的:观察妇科腹腔镜手术CO2气腹合并体位改变对心脏电生理的影响。方法:选择择期行妇科腹腔镜手术的患者30例,全身麻醉,气腹压12 mm Hg,头低位15°。记录并分析麻醉前(T0)、麻醉后(T1)、气腹后1 min(T2)、气腹头低位后30 min(T3)、放气平卧位后30 min(T4)时的基本监测指标和QT间期(QT)、T波峰末间期(Tp-e),心率校正QT间期(QTc),QT离散度(QTd),Tp-e/QT的变化。结果:与T0时刻相比,T1时刻QTd明显延长(P<0.05),T2、T3、T4时刻QT、QTc、QTd、Tp-e、Tp-e/QT明显延长(P<0.05);与T2时刻相比,T3时刻QTc、QTd、Tp-e、Tp-e/QT明显延长(P<0.05)。结论:妇科腹腔镜手术中CO2气腹合并头低脚高位会延长心室复极时程,破坏心脏电生理稳定性,可能增加心血管事件发生率。展开更多
