个体与运动综合征（LS）需要护理服务，由于运动和肌肉骨骼系统的问题。与没有LS的个体相比，患有LS的个体通常行走速度较慢。然而，患有和不患有LS的个体在下肢运动学和步态方面的差异尚不完全清楚。本研究旨在利用可穿戴传感器阐明LS患者的步态运动学特征。我们评估了125名使用公共健康促进设施的参与者（平均年龄73.0±6.7岁）。根据25题老年人机车功能量表（GLFS-25），这些参与者被分为非ls组（GLFS-25 < 7）， ls - 1阶段（GLFS-25 7 - 16）和ls -2阶段（GLFS-25≥16）组（GLFS-25得分越大表明机车能力越差）。采用作者自行开发的基于7个惯性传感器的运动分析系统“h -步态系统”，对10米步行试验中的时空参数和下肢运动学进行了分析。比较各组在站立和摇摆阶段的关节峰值角，以及步态速度、节奏和步长。非ls组69人，ls 1期组33人，ls 2期组23人。与非ls组相比，ls - 2期组髋伸（9.5±5.3°vs 4.2±8.2°，P = 0.002）、髋屈曲（34.2±8.8°vs 28.5±9.5°，P = 0.026）和膝关节屈曲（65.2±18.7°vs 50.6±18.5°，P = 0.005）的峰值角明显小于ls组。ls - 1期和ls - 2期组的平均步态速度显著低于非ls组（非ls组：1.3±0.2 m/s， ls - 1期：1.2±0.2 m/s， ls - 2期：1.1±0.2 m/s, P < 0.001）。与非ls组相比，ls - 2期组的下肢运动学有显著差异，包括髋关节伸展、髋关节屈曲和膝关节屈曲的峰值角较小。对于归类为ls - 2阶段的个体，评估和改善这些步态中的小峰值关节角将是有用的。
Individuals with locomotive syndrome (LS) require nursing care services owing to problems with locomotion and the musculoskeletal system. Individuals with LS generally have a reduced walking speed compared with those without LS. However, differences in lower-limb kinematics and gait between individuals with and without LS are not fully understood. This study aimed to clarify the characteristics of the gait kinematics of individuals with LS using wearable sensors. We assessed 125 participants (mean age 73.0 ± 6.7 years) who used a public health promotion facility. Based on the 25-question Geriatric Locomotive Function Scale (GLFS-25), these participants were grouped into the non-LS (GLFS-25 < 7), LS-stage 1 (GLFS-25 7–16), and LS-stage 2 (GLFS-25 ≥ 16) groups (larger GLFS-25 scores indicate worse locomotive ability). Spatiotemporal parameters and lower-limb kinematics during the 10-m walk test were analyzed by the “H-Gait system”, which is a motion analysis system that was developed by the authors and is based on seven inertial sensors. The peak joint angles during the stance and swing phases, as well as the gait speed, cadence, and step length were compared among all groups. There were 69 participants in the non-LS group, 33 in the LS-stage 1 group, and 23 in the LS-stage 2 group. Compared with the non-LS group, the LS-stage 2 group showed significantly smaller peak angles of hip extension (9.5 ± 5.3° vs 4.2 ± 8.2°, P = 0.002), hip flexion (34.2 ± 8.8° vs 28.5 ± 9.5°, P = 0.026), and knee flexion (65.2 ± 18.7° vs 50.6 ± 18.5°, P = 0.005). The LS-stage 1 and LS-stage 2 groups had a significantly slower mean gait speed than the non-LS group (non-LS: 1.3 ± 0.2 m/s, LS-stage 1: 1.2 ± 0.2 m/s, LS-stage 2: 1.1 ± 0.2 m/s, P < 0.001). The LS-stage 2 group showed significantly different lower-limb kinematics compared with the non-LS group, including smaller peak angles of hip extension, hip flexion, and knee flexion. It would be useful to assess and improve these small peak joint angles during gait for individuals classified as LS-stage 2.
