Test-retest Reliability And Performance Differences Between Traditional Upper Quarter Y-balance Test And Two Modifications

A striking range of individual differences has recently been reported in three different visual search tasks. These differences in performance can be attributed to strategy, that is, the efficiency with which participants control their search to complete the task quickly and accurately. Here, we ask whether an individual’s strategy and performance in one search task is correlated with how they perform in the other two. We tested 64 observers and found that even though the test–retest reliability of the tasks was high, an observer’s performance and strategy in one task was not predictive of their behaviour in the other two. These results suggest search strategies are stable over time, but context-specific. To understand visual search, we therefore need to account not only for differences between individuals but also how individuals interact with the search task and context.

Community Dwelling Older Adults

BackgroundPerceived ability or confidence plays an important role in determining function and behavior. The modified Gait Efficacy Scale (mGES) is a 10-item self-report measure used to assess walking confidence under challenging everyday circumstances.ObjectiveThe purpose of this study was to determine the reliability, internal consistency, and validity of the mGES as a measure of gait in older adults.DesignThis was a cross-sectional study.MethodsParticipants were 102 community-dwelling older adults (mean [±SD] age=78.6±6.1 years) who were independent in ambulation with or without an assistive device. Participants were assessed using the mGES and measures of confidence and fear, measures of function and disability, and performance-based measures of mobility. In a subsample (n=26), the mGES was administered twice within a 1-month period to establish test-retest reliability through the intraclass correlation coefficient (ICC [2,1]). The standard error of measure (SEM) was determined from the ICC and standard deviation. The Cronbach α value was calculated to determine internal consistency. To establish the validity of the mGES, the Spearman rank order correlation coefficient was used to examine the association with measures of confidence, fear, gait, and physical function and disability.ResultsThe mGES demonstrated test-retest reliability within the 1-month period (ICC=.93, 95% confidence interval=.85, .97). The SEM of the mGES was 5.23. The mGES was internally consistent across the 10 items (Cronbach α=.94). The mGES was related to measures of confidence and fear (r=.54–.88), function and disability (Late-Life Function and Disability Instrument, r=.32–.88), and performance-based mobility (r=.38–.64).LimitationsThis study examined only community-dwelling older adults. The results, therefore, should not be generalized to other patient populations.ConclusionThe mGES is a reliable and valid measure of confidence in walking among community-dwelling older adults.

Test Retest Reliability

Abstract Background The Performance-based measure of Executive Functions (PEF) with four domains is designed to assess executive functions in people with schizophrenia. The purpose of this study was to examine the test-retest reliability of the PEF administered by the same rater (intra-rater agreement) and by different raters (inter-rater agreement) in people with schizophrenia and to estimate the values of minimal detectable change (MDC) and MDC%. Methods Two convenience samples (each sample, n = 60) with schizophrenia were conducted two assessments (two weeks apart). The intraclass correlation coefficient (ICC) was analyzed to examine intra-rater and inter-rater agreements of the test-retest reliability of the PEF. The MDC was calculated through standard error of measurement. Results For the intra-rater agreement study, the ICC values of the four domains were 0.88–0.92. The MDC (MDC%) of the four domains (volition, planning, purposive action, and perfromance effective) were 13.0 (13.0%), 12.2 (16.4%), 16.2 (16.2%), and 16.3 (18.8%), respectively. For the inter-rater agreement study, the ICC values of the four domains were 0.82–0.89. The MDC (MDC%) were 15.8 (15.8%), 17.4 (20.0%), 20.9 (20.9%), and 18.6 (18.6%) for the volition, planning, purposive action, and performance effective domains, respectively. Conclusions The PEF has good test-retest reliability, including intra-rater and inter-rater agreements, for people with schizophrenia. Clinicians and researchers can use the MDC values to verify whether an individual with schizophrenia shows any real change (improvement or deterioration) between repeated PEF assessments by the same or different raters.

Test Retest Reliability

Context:The Star Excursion Balance Test (SEBT) is often used to train and assess dynamic balance and neuromuscular control. Few studies have examined hip- and thigh-muscle activation during the SEBT.Objective:To quantify hip- and thigh-muscle activity during the SEBT.Design:Repeated measures.Setting:Laboratory.Participants:22 healthy individuals, 11 men and 11 women.Methods:EMG measurements were taken as participants completed 3 trials of the anterior (A), medial (M), and posteromedial (PM) reach directions of the SEBT.Main Outcome Measures:Mean EMG data (% maximal voluntary isometric contraction) from the gluteus medius (Gmed), gluteus maximus (Gmax), and vastus medialis (VM) were measured during the eccentric phase of each SEBT reach direction. Test–retest reliability of EMG data across the 3 trials in each direction was calculated. EMG data from each muscle were compared across the 3 reach directions.Results:Test–retest reliability ranged from ICC3,1 values of .91 to .99. A 2-way repeated-measure ANOVA revealed a significant interaction between muscle activation and reach direction. One-way ANOVAs showed no difference in GMed activity between the A and M directions. GMed activity in the A and M directions was greater than in the PM direction. There was no difference in GMax and VM activity across the 3 directions.Conclusion:GMed was recruited most effectively when reaching was performed in the A and M directions. The A, M, and PM directions elicited similar patterns of muscle recruitment for the GMax and VM. During all 3 SEBT directions, VM activation exceeded the 40–60% threshold suggested for strengthening effects. GMed activity also exceeded the threshold in the M direction. GMax activation, however, was below the 40% threshold for all 3 reach directions, suggesting that performing dynamic lower extremity reaching in the A, M, and PM directions may not elicit strengthening effects for the GMax.

Test Retest Reliability

Lateral mobility is integral to many activities of daily living involving transfer from one position to another. The objective of this study was to develop and evaluate the validity and test–retest reliability of a lateral-mobility (LATMOB) task for older adults. Measurements of lateral mobility, balance, and strength and self-reported and performance-based physical functioning were obtained in 63 women and 77 men ≥50 years of age. The LATMOB task was significantly correlated with age, knee-extensor strength, grip strength, functional reach, and one-leg-stance time. Test–retest reliability of the task was excellent. The LATMOB task was highly correlated with the car task. Balance was significantly correlated with time to get into and out of a car and performance on the LATMOB task. The LATMOB task was significantly correlated with the Short Physical Performance Battery score. The LATMOB task is valid and reliable, but additional work is needed to assess its sensitivity to change and predictive validity.

Test Retest Reliability

Background: Isokinetic exercise is commonly used as a benchmark for strength and performance. Objective: The purpose of this investigation was to establish isokinetic fatigue test-retest reliability and examine the learning effect when testing without familiarization. Methods: 22 masters-aged [53±5 years), competitive female cyclists completed 3 separate 50-repetition knee flexion/extension tests on a Biodex, separated by one-week with no familiarization. Test-retest reliability [intra-class correlation [ICC]), 95% confidence intervals [CI), technical error of measurement [TEM) were calculated. Results: ICCs between trials exhibited excellent reliability during extension [.93–.97) and flexion [.93–.97) for all variables except time to peak torque [ICC=.35 and.45 for extension and flexion, respectively) and fatigue index [ICC=.47 for flexion). Relative TEM was minimal for extension between trial 1 and trial 2 [0.27%–0.97%) and between trial 2 and trial 3 [0.27%–1.45%) for all variables. Similar results were observed for flexion between trial 1 and trial 2 [0.87%–2.45%) and between trial 2 and trial 3 [0.54%–1.10%). No differences [Wilks Λ>.05) existed between trials, indicating no learning effect associated with the tests. Conclusions: There was strong test-retest reliability in masters-aged, female athletes and no learning effect was associated with the Biodex during a knee extension/flexion fatigue protocol.
