摘要

目的：研究惯性传感器 360° 转动测量与运动捕捉和认知障碍老年人活动能力评估的并发有效性和结构有效性：收集了 31 名参与者（平均年龄为 85.2 岁（SD 5.2））在顺时针（CW）和逆时针（CCW）360° 旋转过程中使用（1）APDM 体戴式惯性传感器和（2）Qualisys 8 摄像机实验室运动捕捉的数据：在转弯持续时间和转弯峰值速度方面，惯性传感器和动作捕捉测量结果的绝对一致性非常好（ICC = 0.96-0.98）。惯性传感器的转弯测量结果与定时上下楼、短期体能测试和 90 秒平衡测试的成绩之间存在强到中等程度的相关性。CCW 360°转体持续时间和转体峰值速度的ROC曲线分析区分了行动障碍的高风险和低风险：惯性传感器 360° 转体测量与动作捕捉和行动能力评估具有并发有效性和结构有效性。

Validity of Instrumented 360° Turn Test in Older Adults with Cognitive Impairment.

Aims: To examine concurrent and construct validity of inertial sensor 360°turn measures in relation with motion capture and mobility assessments in cognitively impaired older adults.

Methods: Data was collected in 31 participants, mean age 85.2 (SD 5.2), during clockwise (CW) and counter clockwise (CCW) 360° turns using (1) APDM body-worn inertial sensors and (2) Qualisys 8-camera laboratory-based motion capture.

Results: Absolute agreement between inertial sensor and motion capture measures was excellent for turn duration and turn peak velocity (ICC = 0.96-0.98). Strong to moderate correlations were present between inertial sensor turn measures and performance on the Timed Up and Go, Short Physical Performance Battery and 90-s Balance Test. ROC curve analysis of CCW 360° turn duration and turn peak velocity distinguished higher risk versus lower risk for mobility disability.

Conclusions: Inertial sensor 360° turn measures demonstrated concurrent and construct validity in relation to motion capture and mobility assessments.

期刊介绍： This comprehensive journal is recognized for its useful balance of research and clinical practice articles. For more than twenty five years Physical & Occupational Therapy in Geriatrics has functioned as a forum for allied health professionals as well as others with a focus on rehabilitation of the geriatric client to share information, clinical experience, research, and therapeutic practice. Each issue focuses on current practice and emerging issues in the care of the older client, including rehabilitation and long-term care in institutional and community settings, and innovative programming; the entire range of problems experienced by the elderly; and the current skills needed for working with older clients.
