The Gait Profile Score (GPS) provides a composite measure of the quality of joint movement during walking, but the relationship between this measure and metabolic cost, temporal (e.g. walking speed) and spatial (e.g. stride length) parameters in stroke survivors has not been reported.
The aims of this study were to compare the GPS (paretic, non-paretic, and overall score) of young stroke survivors to the healthy able-bodied control and determine the relationship between the GPS and metabolic cost, temporal (walking speed, stance time asymmetry) and spatial (stride length, stride width, step length asymmetry) parameters in young stroke survivors to understand whether the quality of walking affects walking performance in stroke survivors.
Thirty-nine young stroke survivors aged between 18 and 65years and 15 healthy age-matched able-bodied controls were recruited from six hospital sites in Wales, UK. Joint range of motion at the pelvis, hip, knee and ankle, and temporal and spatial parameters were measured during walking on level ground at self-selected speed with calculation of the Gait Variable Score and then the GPS.
GPS for the paretic leg (9.40° (8.60-10.21) p < 0.001), non-paretic leg (11.42° (10.20-12.63) p < 0.001) and overall score (11.18° (10.26-12.09) p < 0.001)) for stroke survivors were significantly higher than the control (4.25° (3.40-5.10), 5.92° (5.11 (6.73)). All parameters with the exception of step length symmetry ratio correlated moderate to highly with the GPS for the paretic, non-paretic, and/or overall score (ρ = <-0.732 (p < 0.001)).
The quality of joint movement during walking measured via the GPS is directly related to the speed and efficiency of walking, temporal (stance time symmetry) and spatial (stride length, stride width) parameters in young stroke survivors.
步态廓清评分（GPS）提供了一个关节运动质量的综合测量指标，但在年轻中风幸存者中，它与代谢成本、时间（例如，行走速度）和空间（例如，步长）参数之间的关系尚未得到报道。
本研究的目的是比较年轻中风幸存者的 GPS（患侧、非患侧和整体评分）与健康对照组，并确定 GPS 与代谢成本、时间（步行速度、支撑时间不对称）和空间（步长、步宽、步长不对称）参数之间的关系，以了解行走质量是否会影响中风幸存者的行走表现。
从英国威尔士的六个医院招募了 39 名年龄在 18 至 65 岁之间的年轻中风幸存者和 15 名年龄匹配的健康对照组。在水平地面上以自选择速度行走时，测量了骨盆、髋关节、膝关节和踝关节的关节活动范围以及时间和空间参数，并计算了步态变量评分和 GPS。
中风幸存者的患侧腿（9.40°（8.60-10.21），p<0.001）、非患侧腿（11.42°（10.20-12.63），p<0.001）和整体评分（11.18°（10.26-12.09），p<0.001）的 GPS 明显高于对照组（4.25°（3.40-5.10），5.92°（5.11（6.73））。除了步长对称比之外，所有参数都与患侧、非患侧和/或整体评分的 GPS 中度至高度相关（ρ=<-0.732（p<0.001））。
通过 GPS 测量的行走时关节运动质量与年轻中风幸存者的行走速度和效率、时间（支撑时间对称）和空间（步长、步宽）参数直接相关。
