背景。对于中风患者来说，翻身是一项具有挑战性的任务。然而，有效针对转向的计划尚未制定。客观的。本研究探讨了一种新型的基于转身的跑步机训练对慢性中风患者的转身表现、步态对称性、平衡和肌肉力量的影响。方法。 30 名参与者被随机分配到实验组，接受 30 分钟的基于转身的跑步机训练，或对照组，接受 30 分钟的常规跑步机训练，然后在 4 周内进行 12 次 10 分钟的一般锻炼计划。在基线、训练后和 1 个月随访时评估主要结果（地面转弯速度和直走的时空特征）和次要结果（平衡和肌肉力量）。结果。每组有 15 名参与者，年龄为 54.2 +/- 9.6 岁，中风后 2.6 +/- 1.9 年，在地面上行走的速度为 0.59 +/- 0.28 m/s。 16 人患有缺血性中风，14 人患有出血性中风。无论转弯方向如何，组间和时间对转弯速度、直行性能（速度和时间对称性）、臀部肌肉和踝背屈肌的力量以及平衡控制（伯格平衡量表、向前方向的重量转移和前庭功能）都有显着的交互作用。与对照组相比，实验组在训练后这些指标上表现出更大的改善。这些改进在 1 个月的后续评估中持续存在。结论。基于转身的跑步机训练可能是提高慢性中风患者的转身能力、步态对称性、肌肉力量和平衡控制的可行且有效的策略。
Background. Turning is a challenging task for stroke patients. Programs that effectively target turning, however, have not been established. Objective. This study examined the effects of a novel turning-based treadmill training on turning performance, gait symmetry, balance, and muscle strength in patients with chronic stroke. Methods. Thirty participants were randomly assigned to the experimental group that received 30 minutes of turning-based treadmill training or to the control group that received 30 minutes of regular treadmill training, followed by a 10-minute general exercise program for 12 sessions over 4 weeks. Primary outcomes (overground turning speed and temporal-spatial characteristics of straight walking) and secondary outcomes (balance and muscle strength) were assessed at baseline, after training, and at 1-month follow-up. Results. Fifteen participants per group were 54.2 +/- 9.6 years old, poststroke 2.6 +/- 1.9 years, and walked overground at 0.59 +/- 0.28 m/s. Sixteen had an ischemic and 14 a hemorrhagic stroke. There were significant interaction effects between groups and time on turning speed regardless of turning direction, straight-walking performance (speed and temporal symmetry), strength of hip muscles and ankle dorsiflexors, and balance control (Berg Balance Scale, weight shifting in the forward direction and vestibular function). Compared with the control group, the experimental group showed greater improvements in these measures following training. These improvements persisted at the 1-month follow-up evaluation. Conclusions. Turning-based treadmill training may be a feasible and effective strategy to improve turning ability, gait symmetry, muscle strength, and balance control for individuals with chronic stroke.
