研究概览
简要总结
The aim of the study is to assess various aspects of reliability and validity of two sit-to-stand tests, the Five Times Sit to Stand Test (5TSTS) and the 30-Second Sit to Stand Test (30SSTS). The tests will be performed by patients after lower-limb amputation who have been newly fitted with a prosthesis. Each test will be performed with and without the prosthesis on two occasions: on the first day when the patients will be able to walk independently with their prosthesis and two weeks later. On the same two occasions, the patients will also perform three walking tests (in randomised order): the L-test, the 10-Metre Walk Test and the 6-Minute Walk Test. In addition, the patients will repeat the 5TSTS and the 30SSTS one day after the first assessment. The results will be used to detect the presence of a floor effect, assess repeatability and concurrent validity, as well as estimate minimal detectable change and effects size for the effect of rehabilitation.
详细描述
All the tests will be performed using standardised protocols and technical aids. The assessments will be performed in the afternoon (after the daily rehabilitation program). The patients who will be able to perform the 5TSTS will perform that test first. If those patients will bill able to stand up within 30 seconds on each of the five trials, the 30SSTS will be performed next; otherwise, the number of times that the patient was able to complete the transition to the standing position will be recorded and taken as the 30SSTS result. Repetition of the outcome measurements will not serve to simply use the differences as the actual outcomes, but will serve to assess floor effect (the percentage of patients attaining the minimum possible score) on each occasion, to assess repeatability (intra-class correlation between the measurements on two consecutive days), minimal detectable change (calculated from the standard error of measurement, which will be estimated from the correlation between the measurements at the start and after two weeks) and effect size (difference between the mean measurements at the start and after two weeks, divided by the standard deviation at the start). In addition, the repeated measurements will be used to assess concurrent validity in terms of the correlation between the sit-to-stand tests and the walking tests on two occasions (at the start and after two weeks).

结局指标
主要结局
Five Times Sit to Stand Test (5TSTS) - After two weeks
时间窗: Two weeks after the start of the study
The 5TSTS assesses functional lower extremity strength, transitional movements and balance. The outcome is the tame required by the participant to complete the task.
30-Second Sit to Stand Test (30SSTS) - Start
时间窗: At the start of the study
The 30SSTS assesses leg strength and endurance. The outcome is the number of times that the participant is able to completely stand up from the chair within 30 secons.
30-Second Sit to Stand Test (30SSTS) - After one day
时间窗: One day after the start of the study
The 30SSTS assesses leg strength and endurance. The outcome is the number of times that the participant is able to completely stand up from the chair within 30 secons.
