治疗、锻炼或机器人设备能够最大化步态功能的程度是神经康复中的一个主要未解决的问题。有几个因素可能会影响步态结果，例如任务与地上行走的相似性、肢体内和肢体间的协调程度以及每个器械的周期间变异性。我们的目的是比较10名非残疾成年人（6名男性;平均年龄22.7 ± 2.9岁，范围20-29）在四种运动任务（地上行走、跑步机行走、椭圆训练和固定自行车）中的下肢运动学、协调性和变异性。所有人首先以自选速度进行了四次地上行走试验，并使用平均时空数据来调整其他条件。关节位置，偏移，和步态偏差指数（GDI）进行了比较，以评估运动学的相似性。将时间序列数据与肢体内和肢体间相关，以分别评估肢体内和肢体间协调。量化节奏的变异性，以评估与地上行走相比，运动节奏的限制程度。跑步机行走最接近地面，GDI值几乎重叠，加强了其步态训练的适当性。骑自行车显示出最大的GDI差异，从地上，椭圆接近，但仍然是一个显着的距离，所有三个。骑自行车显示更大的髋关节往复运动骑自行车和椭圆显示更强的肢体内协同作用，在髋关节和膝关节比其他两个。基于运动学，结果表明，椭圆训练可能有更大的转移到地上步行比骑自行车和骑自行车可能是更有用的，以提高相互协调。需要进一步评价这些器械在神经步态障碍中的作用。
The extent to which therapeutic, exercise or robotic devices can maximize gait function is a major unresolved issue in neurorehabilitation. Several factors may influence gait outcomes such as similarity of the task to overground walking, degree of coordination within and across limbs, and cycle-to-cycle variability in each device. Our objective was to compare lower extremity kinematics, coordination and variability during four locomotor tasks: overground walking, treadmill walking, elliptical training and stationary cycling in 10 non-disabled adults (6 male; mean age 22.7 ± 2.9 yrs, range 20–29). All first performed four overground walking trials at self-selected speed with mean temporal–spatial data used to pace the other conditions. Joint positions, excursions, and the Gait Deviation Index (GDI) were compared across conditions to evaluate kinematic similarity. Time-series data were correlated within and across limbs to evaluate intralimb and interlimb coordination, respectively. Variability in cadence was quantified to assess how constrained the locomotor rhythm was compared to overground walking. Treadmill walking most closely resembled overground with GDI values nearly overlapping, reinforcing its appropriateness for gait training. Cycling showed the largest GDI difference from overground, with elliptical closer but still a significant distance from all three. Cycling showed greater hip reciprocation Cycling and elliptical showed stronger intralimb synergism at the hip and knee than the other two. Based on kinematics, results suggest that elliptical training may have greater transfer to overground walking than cycling and cycling may be more useful for enhancing reciprocal coordination. Further evaluation of these devices in neurological gait disorders is needed.
