Abstract：
BACKGROUND: The ability to walk is a key issue for independent old age. Optimizing older peoples\' opportunities for an autonomous and active life and reducing health disparities requires a better understanding of how to support independent mobility in older people. With increasing age, changes in gait parameters such as step length and cadence are common and have been shown to increase the risk of mobility decline. However, gait assessments are typically based on laboratory measures, even though walking in a laboratory environment may be significantly different from walking in outdoor environments.
OBJECTIVE: This project will study alterations in biomechanical features of gait by comparing walking on a treadmill in a laboratory, level outdoor, and hilly outdoor environments. In addition, we will study the possible contribution of changes in gait between these environments to outdoor mobility among older people.
METHODS: Participants of the study were recruited through senior organizations of Central Finland and the University of the Third Age, Jyväskylä. Inclusion criteria were community-dwelling, aged 70 years and older, able to walk at least 1 km without assistive devices, able to communicate, and living in central Finland. Exclusion criteria were the use of mobility devices, severe sensory deficit (vision and hearing), memory impairment (Mini-Mental State Examination ≤23), and neurological conditions (eg, stroke, Parkinson disease, and multiple sclerosis). The study protocol included 2 research visits. First, indoor measurements were conducted, including interviews (participation, health, and demographics), physical performance tests (short physical performance battery and Timed Up and Go), and motion analysis on a treadmill in the laboratory (3D Vicon and next-generation inertial measurement units [NGIMUs]). Second, outdoor walking tests were conducted, including walking on level (sports track) and hilly (uphill and downhill) terrain, while movement was monitored via NGIMUs, pressure insoles, heart rate, and video data.
RESULTS: A total of 40 people (n=26, 65% women; mean age 76.3, SD 5.45 years) met the inclusion criteria and took part in the study. Data collection took place between May and September 2022. The first result is expected to be published in the spring of 2024.
CONCLUSIONS: This multidisciplinary study will provide new scientific knowledge about how gait biomechanics are altered in varied environments, and how this influences opportunities to participate in outdoor activities for older people.

摘要：
背景：行走能力是独立老年的关键问题。优化老年人自主和积极生活的机会并减少健康差距需要更好地理解如何支持老年人的独立流动。随着年龄的增长,步长和步频等步态参数的变化是常见的，并且已被证明会增加行动能力下降的风险。然而,步态评估通常基于实验室测量，即使在实验室环境中行走可能与在室外环境中行走明显不同。
目的：该项目将通过比较在实验室的跑步机上行走来研究步态生物力学特征的改变，水平户外，和丘陵户外环境。此外,我们将研究这些环境之间的步态变化对老年人户外活动的可能贡献。
方法：这项研究的参与者是通过芬兰中部和第三年龄大学的高级组织招募的，于韦斯凯莱。纳入标准是社区住宅，70岁及以上，能够在没有辅助设备的情况下行走至少1公里，能够沟通,住在芬兰中部。排除标准是使用移动设备，严重的感觉缺陷（视觉和听觉），记忆障碍(简易精神状态检查≤23)，和神经系统疾病(例如，中风,帕金森病,和多发性硬化症）。研究方案包括2次研究访问。首先,进行了室内测量，包括采访(参与，健康,和人口统计），物理性能测试（短物理性能电池和定时和启动），在实验室的跑步机上进行运动分析（3DVicon和下一代惯性测量单元[NGIMU]）。第二,进行了户外行走测试，包括在水平（运动跑道）和丘陵（上坡和下坡）地形上行走，虽然运动是通过NGIMU监测的，压力鞋垫,心率,和视频数据。
结果：共有40人（n=26，65％为女性；平均年龄76.3，SD5.45岁）符合纳入标准并参加了研究。数据收集发生在2022年5月至9月之间。第一个结果预计将于2024年春季发布。
结论：这项多学科研究将提供有关步态生物力学在各种环境中如何改变的新科学知识。以及这如何影响老年人参加户外活动的机会。
