目的：评估具有横向截肢（TTA）的人的稳定性限制（LOS），并确定假体对齐对运动控制策略的影响。设计：启用：设置试验：启动：机业学实验室大学医院。参与者：男性TTA患者（n = 10）和对照组（n = 17）。间接：假肢对齐。结果指标：对于LOS测试，最大偏移，端点偏移，方向控制，运动速度和反应时间在向前方向倾斜，朝向截肢的腿/右腿，向后，朝向向后，朝向未吸引的腿/左腿。使用以下5个假肢对准进行测量：最佳对齐，假体短1cm，假体更长的时间更长1厘米，而假肢则在5个额外的Prantar屈曲和5个额外的背屈屈服中。对照组，最大偏移和方向控制较低（P
Objectives: To evaluate the limits of stability (LOS) in persons with transtibial amputation (TTA), and to determine the effects of prosthetic alignment alterations on motor control strategies.Design: Before-and-after trial.Setting: A kinesiology laboratory at a university hospital.Participants: Male patients with TTA (n = 10) and controls (n = 17).Interventions: Prosthetic alignment.Main Outcome Measures: For the LOS test, the maximum excursion, endpoint excursion, direction control, movement velocity, and reaction time with inclination in the forward direction, toward the amputated leg/right leg, and in the backward direction, and toward the nonamputated leg/left leg. Measurements were performed using the following 5 prosthetic alignments: the optimal alignment, with the prosthesis shorter by 1cm, with the prosthesis longer by 1cm, and with the prosthetic foot in 5 of extra plantar flexion and 5 of extra dorsiflexion.Results: Compared with the control group, maximum excursion and direction control were lower (P
