Reliability of the “Expanded Get-Up-and-Go-Test” (ETGUG) in assessing basic movement ability in patients qualified for surgery due to pulmonary cancer
Journal Title: Rehabilitacja Medyczna - Year 2011, Vol 15, Issue 4
Abstract
Background: The Expanded Get-Up-and-Go-Test (ETGUG) allows for the measurement of the basic movement functions of daily life. This test has not been universally applied to date and no sufficient surveys as to its reliability have so far been conducted.Aim: To examine the intra-rater and inter-rater reliability of measurements done using ETGUG in patients admitted for surgery treatment as a result of lung cancer. Research project: Assessment of the diagnostic test.Method: 22 men aged from 24 to 85 years (mean 64.45 ±11.38) were examined before a planned lobectomy due to lung cancer. The test was performed three times during one hour; examinations 1 and 3 were conducted by the same examiner. The total test time and times of the test stages were registered: from the initiation of rising from a chair up to reaching the 2-nd meter (0-2), march from the 2-nd to the 8-th meter (2-8), 180° turn (8-12), march from the 12-th to the 18-th meter (12-18) march stopping, 180° turn – chair sitting (18-20).The Intraclass Correlation Coefficients (ICC) of the measurements 1 and 3 (intra-rater), and measurements 2 and 3 (inter-rater) were calculated. The total times of the 1-st and the 3-rd measurement were compared (test t) to check if a possible learning effect occurs.Outcomes: The reliability of the intra-rater measurements demonstrated a good degree of relevance (ICC >0.75) for total time measurements (ICC = 0.78) and medium grade relevance (ICC > 0.50 < 0.75) of the stage times measurements 0-2, 2-8, 8-12, 12-18, 18-20 (ICC respectively: 0.71; 0.74; 0.62; 0.58; 0.70). In the case of an inter-rater examination, a good relevance for the total time (ICC=0.88) and of the measurements of the stage times 2-8, 8-12, 18-20 (ICC respectively: 0.83; 0.77; 0.80) and the medium grade relevance of measurements 0-2 and 12-18 (ICC respectively: 0.63, 0.73) were achieved. The time of the Test 1 performance (15.94 ±2.48) was significantly longer than for Test 3 (15.21 ±2.42).Conclusions: The Expanded Get-Up-and-Go-Test demonstrates a good reliability of measurements as conducted by various surveyors. As a test performance a learning effect was noted, it is recommended to apply a trial test and to repeat the examination of intrarater reliability after a preliminary trial test performance.
