直接观察身体功能的优点是提供了一个客观的、可量化的功能测量。我们已经开发了身体表现测试（PPT），它使用模拟各种难度的日常生活活动的任务的观察性能来评估身体功能的多个领域。提供了两个版本：一个九项量表，包括写一个句子，模拟吃饭，360度旋转，穿上和脱下夹克，举起一本书并把它放在架子上，从地板上捡起一分钱，50英尺步行测试，爬楼梯（分为两项）;和一个七项量表，不包括楼梯。PPT不到10分钟就能完成，只需要几个简单的道具。然后，我们使用183名受试者（平均年龄，79岁）在六个settins，包括四个临床实践（帕金森病患者之一），董事会和护理之家，和老年人的公寓，测试PPT的有效性。PPT是可靠的（Cronbach's α = 0.87和0.79，评分者间信度= 0.99和0.93，分别为9项和7项测试），并证明了与自我报告的身体功能测量的同时有效性。两种量表的PPT评分与改良Rosow-Breslau、日常生活工具和基本活动量表以及Tinetti步态评分高度相关（0.50至0.80）。PPT的得分与自我报告的健康状况、认知状况和心理健康（0.24至0.47）呈中度相关，与年龄呈负相关（-0.24和-1.8）。因此，PPT也证明了结构效度。PPT是一种很有前途的身体功能客观测量方法，但其筛查、监测和预测的临床和研究价值仍有待确定。
Direct observation of physical function has the advantage of providing an objective, quantifiable measure of functional capabilities. We have developed the Physical Performance Test (PPT), which assesses multiple domains of physical function using observed performance of tasks that simulate activities of daily living of various degrees of difficulty. Two versions are presented: a nine-item scale that includes writing a sentence, simulated eating, turning 360 degrees, putting on and removing a jacket, lifting a book and putting it on a shelf, picking up a penny from the floor, a 50-foot walk test, and climbing stairs (scored as two items); and a seven-item scale that does not include stairs. The PPT can be completed in less than 10 minutes and requires only a few simple props. We then tested the validity of PPT using 183 subjects (mean age, 79 years) in six settins including four clinical practices (one of Parkinson''s disease patients), a board-and-care home, and a senior citizens'' apartment. The PPT was reliable (Cronbach''s alpha = 0.87 and 0.79, interrater reliability = 0.99 and 0.93 for the nine-item and seven-item tests, respectively) and demonstrated concurrent validity with self-reported measures of physical function. Scores on the PPT for both scales were highly correlated (.50 to .80) with modified Rosow - Breslau, Instrumental and Basic Activities of Daily Living scales, and Tinetti gait score. Scores on the PPT were more moderately correlated with self-reproted health status, cognitive status, and mental health (.24 to .47), and negatively with age (-.24 and -1.8). Thus, the PPT also demonstrated construct validity. The PPT is a promising objective measurement of physical function, but its clinical and research value for screening, monitoring, and prediction will have to be determined.
