[Purpose] The aim of this study was to investigate the effect of segmental weight of the prosthesis on hemodynamic responses and energy expenditure in lower extremity amputees. [Subjects and Methods] Thirteen patients with a mean age of 44 ± 15.84 years and with unilateral transtibial, transfemoral and Syme's amputation were included to the study. The difference between the lightest and the heaviest prosthesis, 250 g used as the weight. All the patients completed the measurements first without weight and then with 250 g weight on the ankle joint. The blood pressure and heart rate of the patients were recorded before and after Six Minute Walk Test (6MWT) and 10 stairs up & down stairs test. Physiological Cost Index was used to calculate the energy expenditure. [Results] Heart rate and energy expenditure increased significantly when without weight and with weight results compared. [Conclusion] We conclude that the segmental weight of the prosthetic limb has a significant effect on the heart rate and energy expenditure but has no effect on the systolic and diastolic blood pressure of lower limb amputees. In order to generalize our results to lower limb amputees, more patients need to be included in future studies.
[目的]本研究旨在探讨假肢节段重量对下肢截肢者血流动力学反应和能量消耗的影响。[对象与方法]本研究纳入13例平均年龄为44±15.84岁的单侧胫部、股部和赛姆截肢患者。最轻和最重的假肢之间的差异为250g，以此作为重量。所有患者先在无负重状态下完成测量，然后在踝关节处增加250g重量后再次完成测量。在6分钟步行试验（6MWT）和上下10级楼梯试验前后记录患者的血压和心率。使用生理成本指数来计算能量消耗。[结果]与无负重和有负重结果相比，心率和能量消耗显著增加。[结论]我们得出结论，假肢节段重量对下肢截肢者的心率和能量消耗有显著影响，但对其收缩压和舒张压没有影响。为了将我们的结果推广到下肢截肢者，未来的研究需要纳入更多患者。
