Purpose: Performance-based outcome measures are becoming increasingly important in health care. The 2-minute walk test (2MWT) and the Timed Up and Go test (TUG) are frequently used in clinical trials as performance-based tests in many diseases including osteoarthritis. The purposes of this study were: (1) to determine test-retest reliability of data for the 2MWT and the TUG; (2) to determine minimal detectable change (MDC) scores for the TUG and 2MWT in patients with total hip arthroplasty (THA). Methods: 37 patients, who had undergone primary THA, were included. Patients twice performed trials for the 2MWT and TUG on the same day. In addition to demographic data of patients, the Harris Hip Score, 2MWT and TUG scores were recorded. Results: The TUG and 2MWT showed excellent test-retest reliability. The Intraclass correlation coefficient ICC (2,1), Standard error of measurement (SEM) and minimal detectable chance at the 95% CI (MDC95) for TUG were 0.96, 0.59 seconds and 1.62 seconds respectively. The ICC (2,1), SEM and MDC95 for 2MWT were 0.96, 6.37 m and 17.56 m respectively. Conclusion: Clinicians and researchers can be confident that greater changes than 1.62 seconds for TUG and 17.56 m for the 2MWT over time represent a real clinical change in rehabilitation process in patients with THA. Both the 2MWT and TUG may assist in early identification of patients who may need additional rehabilitation to reduce the potential for poor outcomes after THA. Therefore, both of these tests can be used in a clinical setting with a small measurement error.

Abstract Background The L test is a modified version of the timed up and go test (TUG) with an L-shaped walking path. The L test is more extensive than other performance tests, especially in turn direction and specific tasks. The study aimed to evaluate the test-retest reliability, concurrent validity, and minimal detectable change of the L test in patients with total hip arthroplasty (THA). A cross-sectional study was conducted with 33 unilateral and primary THA patients. The L test was performed twice with an interval of an hour on the same day for the test-retest reliability. Timed up and go test (TUG), five times sit to stand test (FTST), and Harris hip score (HHS) were carried out for the analysis of the concurrent validity of the L test. Results The mean age of the participants was 74.6 ± 10.3 years. The ICC score of the L test was 0.992. Test-retest reliability was excellent. SEM95 and MDC95 values were 3.39 and 9.39, respectively. Both TUG and HHS were strongly correlated with the L test (r1 = 0.889, r2 = −0.568, p < 0.001). However, there was no significant correlation between FTST and L test (r = 0.024, p > 0.05). Conclusions The L test is valid and reliable performance measurement in patients with primary unilateral THA. MDC95 of the L test is an essential reference for clinicians in the rehabilitation follow-up process of THA patients.

Introduction: The 2-Minute Walk Test (2MWT) is a simple, practical, and less time consuming test. Patients do not get fatigued while performing this test as a part of routine physical examination. 2MWT shows an excellent correlation with other walk tests and can be used as an alternative test in patients with multiple co- morbidities. The reliability of a test is a must for its recommendation to be used in clinics as well as research. Measurement properties have been reported in different populations for 2MWT. However, no data exist for 2MWT in patients with Knee Osteoarthritis (KOA). Aim: To establish the test-retest reliability and Minimal Detectable Change (MDC) scores for the 2MWT in patients with bilateral KOA. Materials and Methods: A prospective test-retest research study designed to assess the reliability of 2MWT. Eighty-two patients with KOA (27 males and 55 females) were included in the study. Health status was assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC). The Numeric Pain Rating Scale (NPRS) and WOMAC were assessed on two consecutive days. Participants performed 2MWT on two different occasions with 48 hours difference in between. Both sessions were conducted for 45 minutes each on a 30 meter walking pathway. Data was analysed using Statistical Package for the Social Sciences (SPSS) version 20.0 for Windows (SPSS Inc., Chicago, IL, USA). Results: 2MWT showed an excellent test-retest reliability. Intraclass Correlation Coefficient (ICC) for 2MWT were 0.98. Test-retest reliability assessed by two trials of 2MWT showed 1st trial mean±SD of 154.33±19.59 m and 2nd trial mean±SD of 156.69±19.68 m. Mean difference±SD between both trials was 2.36±2.74, which was statistically significant (p<0.001). The Standard Error of Measurement (SEM) and Minimal Detectable Change at 95% confidence level (MDC95) for 2MWT were 2.76 and 5.52 meters, respectively. Conclusion: The study recommends that 2MWT can be used as a test for assessing walking capacity among patients with KOA. A change of more than 5.52 meters can be considered as change-free of error. It can be used as an alternative to 6MWT in patients with KOA who cannot tolerate a higher duration/intensity walk test.

Background: With the increasing incidence of Alzheimer disease (AD), determining the validity and reliability of outcome measures for people with this disease is necessary. Objective: The goals of this study were to assess test-retest reliability of data for the Timed “Up & Go” Test (TUG), the Six-Minute Walk Test (6MWT), and gait speed and to calculate minimal detectable change (MDC) scores for each outcome measure. Performance differences between groups with mild to moderate AD and moderately severe to severe AD (as determined by the Functional Assessment Staging [FAST] scale) were studied. Design: This was a prospective, nonexperimental, descriptive methodological study. Methods: Background data collected for 51 people with AD included: use of an assistive device, Mini-Mental Status Examination scores, and FAST scale scores. Each participant engaged in 2 test sessions, separated by a 30- to 60-minute rest period, which included 2 TUG trials, 1 6MWT trial, and 2 gait speed trials using a computerized gait assessment system. A specific cuing protocol was followed to achieve optimal performance during test sessions. Results: Test-retest reliability values for the TUG, the 6MWT, and gait speed were high for all participants together and for the mild to moderate AD and moderately severe to severe AD groups separately (intraclass correlation coefficients ≥.973); however, individual variability of performance also was high. Calculated MDC scores at the 90% confidence interval were: TUG=4.09 seconds, 6MWT=33.5 m (110 ft), and gait speed=9.4 cm/s. The 2 groups were significantly different in performance of clinical tests, with the participants who were more cognitively impaired being more physically and functionally impaired. Limitations: A single researcher for data collection limited sample numbers and prohibited blinding to dementia level. Conclusions: The TUG, the 6MWT, and gait speed are reliable outcome measures for use with people with AD, recognizing that individual variability of performance is high. Minimal detectable change scores at the 90% confidence interval can be used to assess change in performance over time and the impact of treatment.

Abstract Background: Patient’s satisfaction after surgery was traditionally assessed by pre, and post-surgical scores and Patient-Reported Outcome Measures (PROMs) scales. Patients treated by Total hip arthroplasty (THA) usually perform well; therefore, it is useful to have a PROMs’ scale with a low ceiling effect as the Forgotten Joint Score-12 (FJS-12). PROMs have to be validated in the local language to be used. This study aims to perform a psychometric validation of the Italian version of FJS-12 in a group of consecutive patients treated by THA.Methods: Each patient completed both the Italian version of FJS-12 and Western Ontario and McMaster University Osteoarthritis Index (WOMAC) in preoperative evaluation, after two weeks and 1 month, 3 months and 6 months postoperative follow-up. The reliability, internal consistency, test-retest reliability, and measurement error were evaluated.Results: 53 patients were included. Cronbach’s α between 0.6 and 0.9 indicated good internal consistency for the FJS-12. The test-retest reliability was acceptable. The Pearson correlation coefficient between the FJS-12 and WOMAC was 0.238 (P=0.087) at baseline, r = 0.637 (P < 0.001) at 1 month, r = 0.490 (P < 0.001) at 3 months and r = 0.572 (P < 0.001) at 6 months. The ceiling effect was above the acceptable range (15%) for FJS-12 in 1 month (26.4%) and WOMAC in 6 months follow-up (24.5%).Conclusions: An excellent test-retest reliability, a good internal consistency, and a good validity by medium-high correlation with the WOMAC were assessed for FJS-12. However, the responsiveness for the FJS-12 score was not assessed.
