背景随着人们对老年人生活质量的关注日益增加，功能独立性测量（Functional Independence Measure，简称FIA）等测试被广泛用于测量老年人的虚弱程度和护理负担。然而，这些量表在很大程度上是定性的，尤其是在评估基于运动的任务时存在问题。虽然对人体运动进行有效、可靠的分析在技术上是复杂和昂贵的;但红外深度传感器是潜在的低成本、便携式设备，可以为临床测试提供定量方面。为了评估Kinect™传感器在使用经常测量的ADL（椅子站立）提供对人体运动的客观评估方面的实用性，设计横断面研究。设置社区，日本的老年人日托中心。参会人员：男性（n=136）和女性（n=266）年龄在50和93岁之间，包括健康（HE; n=312）和身体虚弱（FR; n= 90）的个体。使用Kinect™ v2对试验进行计时和记录。冠状面角（CPA）是由一条线横切肩中心和腰部相对于垂直轴，并被用来评估椅子的立场运动patterns.ResultsAge的质量，身高，体重组之间没有差异。FR的CPA（29.3 ± 8.3°）显著大于HE（19.5 ± 6.5°）。CPA与年龄呈显著正相关（r=0.148，p<0.01）。CPA识别虚弱的最佳阈值由接受者-操作者特征曲线确定，CPA为23.1°，提供最大的灵敏度（79%）和特异性（73%）组合。这种代偿姿势似乎有助于躯干旋转，同时减少站立时下肢肌肉的努力。因此，CPA可作为老年体弱成人下半身功能下降的指标。
BackgroundWith increasing interest in addressing quality of life of older individuals, tests such as the Functional Independence Measure (FIM) are widely used measures of infirmity and burden of care. However, these scales are largely qualitative and especially problematic when assessing movement-based tasks. While effective, reliable analysis of human movement is technically complicated and expensive; an infrared depth sensor is potentially a low-cost, portable devise which may provide a quantitative aspect to clinical testing.Objectiveto assess the utility of the Kinect™ sensor in providing an objective evaluation of human movement using an oft measured ADL (chair stand).DesignCross-sectional study.SettingCommunity, geriatric day-care center in Japan. Participants: Men (n=136) and women (n=266) between 50 and 93 years of age, consisting of healthy (HE; n=312) and physically frail (FR; n= 90) individuals.MeasurementsSubjects completed two trials of the chair stand, conducted without assistance. Trials were timed and recorded with Kinect™ v2. Coronal plane angle (CPA) was determined by a line transecting the shoulder-center and waist relative to the vertical axis and was used to assess quality of the chair stand movement pattern.ResultsAge, height, and body mass were not different between groups. CPA was significantly greater in FR (29.3 ± 8.3°) than HE (19.5 ± 6.5°). CPA and age were significantly related (r=0.148, p<0.01). An optimal threshold for CPA identifying frailty was determined by a receiver-operator characteristic curve with a CPA of 23.1° providing the greatest combination of sensitivity (79%) and specificity (73%).ConclusionDuring the chair stand, frail older adults adopted a forward lean position (increased CPA) compared to healthy older adults. This compensatory posture appears to facilitate torso rotation while reducing lower-limb muscular effort during standing. As such, CPA serves as an indicator of reduced lower-body function in older, frail adults.
