METHODS: A total of 193 patients from 25 institutions were included. Participants underwent a locomotive syndrome risk test (stand-up test, 2-step test, and Geriatric Locomotive Function Scale-25 questionnaire) and were classified into three stages. Physical activity was quantitatively monitored for one week with 3-axial accelerometer. Physical activity was classified into three categories; (1) Sedentary behavior (0 ∼ ≤ 1.5 metabolic equivalents (METs)), (2) Light physical activity (LPA:1.6 ∼ 2.9 METs), and (3) Moderate to vigorous physical activity (MVPA: ≥3 METs). We investigated the relationship between physical activity, including the number of steps, and the stages after gender- and age- adjustment. We also investigated the relationship between social isolation using Lubben\'s Social Network Scale (LSNS), as social isolation would lead to fewer opportunities to go out and less outdoor walking.
RESULTS: Comparison among the three stages showed significant difference for age (p = 0.007) and Body Mass Index (p < 0.001). After gender-and age-adjustment, there was a significant relation with a decrease in the number of steps (p = 0.002) and with MVPA. However, no relation was observed in sedentary time and LPA. LSNS did not show any statistically significant difference. Moderate to high-intensity physical activity and the number of steps is required for musculoskeletal disorders. The walking, not sedentary time, was associated to the locomotive stages, and this finding indicated the importance of lower extremity exercise.
CONCLUSIONS: Adjusting for age and gender, the number of steps and moderate to vigorous activity levels were necessary to prevent worsening, and there was no effect of sedentary behavior. Merely reducing sedentary time may be inadequate for locomotive disorders. It is necessary to engage in work or exercise that moves lower extremities more actively.
方法:共纳入来自25个机构的193名患者。参与者接受了机车综合征风险测试(站立测试,两步试验,和老年机车功能量表-25问卷),并分为三个阶段。使用3轴加速度计定量监测身体活动一周。身体活动分为三类;(1)久坐行为(0~≤1.5代谢当量(MET)),(2)轻度体力活动(LPA:1.6~2.9MET),和(3)中度至剧烈的体力活动(MVPA:≥3MET)。我们调查了身体活动之间的关系,包括步数,以及性别和年龄调整后的阶段。我们还使用Lubben的社会网络量表(LSNS)调查了社会隔离之间的关系,因为社会孤立会导致更少的外出机会和更少的户外步行。
结果:三个阶段之间的比较显示年龄(p=0.007)和体重指数(p<0.001)的显着差异。经过性别和年龄调整后,与步数减少(p=0.002)和MVPA有显着关系。然而,在久坐时间和LPA中未观察到相关。LSNS没有显示任何统计学上的显著差异。肌肉骨骼疾病需要中等强度到高强度的体力活动和步数。行走,不是久坐的时间,与机车阶段有关,这一发现表明了下肢运动的重要性。
结论:调整年龄和性别,步骤的数量和适度到剧烈的活动水平是必要的,以防止恶化,久坐的行为没有影响。仅减少久坐时间可能不足以用于机车障碍。有必要从事更积极地移动下肢的工作或锻炼。
