![]() These were not consecutive patients as screening resources were not continuously available and consequently more potentially eligible patients were admitted during the period. Patients were included at any time during their admission when they met the inclusion criteria.ĭuring the study period 266 patients referred to physical therapy were screened for eligibility by the three physiotherapists participating in the study. Patients were not eligible, if they were under the age of 18 years, had a stroke caused by trauma, lacked the ability to sit and stand independently, lacked the ability to walk with or without an assistive device (only relevant for TUG), had pain making testing impossible, or were not able to understand verbal or written information in Danish. Patients, who were referred to physical therapy and had a first event of stroke verified by CT/MR-scan or were diagnosed based on clinical symptoms, were screened for eligibility. The purpose was therefore to investigate the relative and absolute reliability of the timed ‘Up & Go’ test (TUG) and ‘30second Chair-Stand’ test (30s-CST) in stroke patients, admitted to an acute stroke unit.Ī convenience sample of hospitalised stroke patients, admitted to the acute stroke unit in the Neurological Department at Herlev Hospital, University of Copenhagen, Denmark, were recruited between October 2013 and June 2014. The absolute reliability was 1.26 in patients with dementia and ranged from 0.7 to 1.27 in patients with OA for a group of patients and the absolute reliability for individual patients were 3.49 in patients with dementia and ranged from 1.64 to 2.6 for patients with OA. In patients with dementia, patients with osteoarthritis (OA) and older adults the test-retest reliability ranged between 0.81–0.98 for 30s-CST. ![]() The reliability of 30s-CST in patients with acute (≤3 months) or chronic stroke (≥6 months) has not been reported. Instead of measuring the time it takes to complete a number of repetitions, the 30s-CST measures the numbers of chair-stands a person can perform in 30 seconds, making it possible to assess a wider variation of functional performance levels, with the possible scoring ranging between 0 and ≥20 repetitions depending on the functional capacity of the subjects. For severely disabled patients it may be too difficult to perform 5 or 10 times sit-to-stand repetitions. Three of the studies also assessed absolute reliability for TUG and found that the standard error of measurement (SEM) was 1.14 seconds, 1.34 seconds and 2.83 seconds, respectively.ĭifferent outcome measures are used to assess sit-to-stand tasks. In chronic stroke patients (≤ 6 months) high relative test-retest reliability with Interclass Correlations Coefficients (ICC) ≥ 0.9 has been observed for TUG. However, the reliability of TUG in patients with acute stroke (≤3 months) has never been reported. These are among the most important aspects of stroke rehabilitation, since critical decisions regarding discharge destination, need for further rehabilitation and assistance after discharge depend on assessment of functional performance and risk of falling. TUG has been used in several studies to assess functional performance and risk of falling in stroke patients. TUG and 30s-CST are easy to administer compared with other performance measures and can easily be implemented in clinical practice. The timed ‘Up & Go’ test (TUG) and ‘30second Chair-Stand’ test (30s-CST) are both outcome measures widely used in different groups of patients to assess functional performance such as walking, turning and the ability to perform sit to stand-tasks. Walking, standing and sitting on a chair are among the most affected activities for stroke patients and are considered important for the independency of everyday life. Knowing both the absolute and relative reliability of an outcome measure, enable clinicians and researchers to evaluate the results on a scientific basis and be 95% confident, that a change in the outcome score represents an actual change in performance, and not just a change caused by measurement error and simple test re-test variation. It is important that functional performance is evaluated with valid and reliable clinical outcome measures. Stroke is one of the most disabling conditions leading to loss of mobility and independency.
