To determine the interrater and intrarater reliability and the validity of the Timed "up and go" test as a measure for physical mobility in elderly patients with an amputation of the lower extremity.
To test interrater reliability, the test was performed for two observers at different times of the same day in an alternating order. To test intrarater reliability, the patients performed the test for one observer on two consecutive visits with an interval of 2 weeks. To test validity, the results of the Timed "up and go" test were compared with the results on the Sickness Impact Profile, 68-item version (SIP68), and the Groningen Activity Restriction Scale (GARS).
Thirty-two patients, age 60 yrs or older, with unilateral transtibial or transfemoral amputation because of peripheral vascular disease.
The Timed "up and go" test showed good intrarater and interrater reliability (r = .93 and .96, respectively). A moderate relationship exists between the Timed "up and go" test and the GARS, a good relationship exists with the "physical subscales" of the SIP68, and there is no relationship with the "mental subscales" of the SIP68.
The Timed "up and go" test is a reliable instrument with adequate concurrent validity to measure the physical mobility of patients with an amputation of the lower extremity.
确定定时起立行走测试在评估老年下肢截肢患者身体活动能力方面的评分者间信度、评分者内信度及效度。
为测试评分者间信度，由两名观察者在同一天不同时间以交替顺序进行该测试。为测试评分者内信度，患者在间隔2周的连续两次就诊时为同一名观察者进行该测试。为测试效度，将定时起立行走测试结果与疾病影响量表68项版本（SIP68）及格罗宁根活动受限量表（GARS）的结果进行比较。
32名年龄60岁及以上、因外周血管疾病导致单侧胫部或股部截肢的患者。
定时起立行走测试显示出良好的评分者内信度和评分者间信度（相关系数分别为0.93和0.96）。定时起立行走测试与GARS之间存在中度相关性，与SIP68的“身体分量表”存在良好相关性，与SIP68的“精神分量表”无相关性。
定时起立行走测试是一种可靠的工具，具有足够的同时效度来评估下肢截肢患者的身体活动能力。
