Reliability and Validity of the Five-Minute Walking Field Test for Estimating V˙O2 peak in Elderly Subjects with Knee Osteoarthritis

The purposes of the present study were (a) to evaluate the test-retest reliability of the Price et al. (1988) 5-min walking field test, (b) to assess the validity of the test as an estimate of aerobic fitness, and (c) to derive a predictive model for estimating peak. The subjects were men and women age ≥50 with knee osteoarthritis. A high intraclass correlation coefficient was obtained in the reliability study, which included 60 subjects who did the 5-min walk twice within a maximum of 11 days. For the validity study, distances walked at the first walking trial were compared with peak values measured by a maximal treadmill test. The best predictive model included the following predictor variables: distance walked in 5 min, age, sex, and weight. Results indicate that the 5-minutc walking field test is a reliable and valid method for estimating peak in this population.

Abstract Background and Purpose. The purpose of this study was to examine the reliability and validity of data obtained with 2 newly developed shuttle run tests (SRT-I and SRT-II) to measure aerobic power in children with cerebral palsy (CP) who were classified at level I or II on the Gross Motor Function Classification System (GMFCS). The SRT-I was developed for children at GMFCS level I, and the SRT-II was developed for children at GMFCS level II. Subjects. Twenty-five children and adolescents with CP (10 female, 15 male; mean age=11.9 years, SD=2.9), classified at GMFCS level I (n=14) or level II (n=11), participated in the study. Methods. To assess test-retest reliability of data for the 10-m shuttle run tests, the subjects performed the same test within 2 weeks. To examine validity, the shuttle run tests were compared with a GMFCS level–based treadmill test designed to measure peak oxygen uptake. Results. Statistical analyses revealed test-retest reliability for exercise time (number of levels completed) (intraclass correlation coefficients of .97 for the SRT-I and .99 for the SRT-II) and reliability for peak heart rate attained during the final level (intraclass correlation coefficients of .87 for the SRT-I and .94 for the SRT-II). High correlations were found for the relationship between data for both shuttle run tests and data for the treadmill test (r=.96 for both). Discussion and Conclusion. The results suggest that both 10-m shuttle run tests yield reliable and valid data. Moreover, the shuttle run tests have advantages over a treadmill test for children with CP who are able to walk and run (GMFCS level I or II). [Verschuren O, Takken T, Ketelaar M, et al.

Abstract Objectives To examine the validity and reliability of the Mandarin version of the Treatment Burden Questionnaire (TBQ) among stroke patients. Background Stroke patients need long-term management of symptoms and life situation, and treatment burden has recently emerged as a new concept that can influence the health outcomes during the rehabilitation process. Methods The convenience sampling method was used to recruit 187 cases of stroke patients in a tertiary grade hospital in Tianjin for a formal investigation. Item analysis, reliability and validity tests were carried out. The reliability test included internal consistency and test–retest reliability. And as well as content, structure and convergent validity were performed for the validity test. Results Of the 187 completed questionnaires, only 180 (96.3%) were suitable for analysis. According to the experts’ evaluation, the I-CVI of each item was from 0.833 to 1.000, and the S-CVI was 0.967. The exploratory factor analysis yielded three-factor components with a cumulative variation of 53.054%. Convergent validity was demonstrated using measures of Morisky’s Medication Adherence Scale 8 (r = –0.450, P < 0.01). All correlations between items and global scores ranged from 0.403 to 0.638. Internal consistency reliability and test–retest reliability were found to be acceptable, as indicated by a Cronbach’s α of 0.824 and an intraclass correlation coefficient of 0.846, respectively. Conclusions The Mandarin TBQ had acceptable validity and reliability. The use of TBQ in the assessment of treatment burden of stroke survivor may benefit health resources allocation and provide tailor therapeutic interventions to construct minimally disruptive care.

Test Retest Reliability

Abstract Introduction Static postural stability is the ability to maintain the posture with minimum sway. Increasing postural sway during standing in different sensory conditions is associated with aging due to decline in sensory and motor functions. Sway area measured by using sway meter is usually simple method for assessing postural stability in elderly subjects. Like many biological measurements, sway area has an intrinsic variability that affects their test-retest reliability and responsiveness of postural stability assessment. The minimal detectable change (MDC) is ability to detect smallest change beyond measurement error that reflects a reliable change. Therefore, the MDC value could provide information of clinical relevance on postural stability. The aims of this study were to determine test-retest reliability and MDC of sway area obtained from sway meter in elderly subjects. Methods Twelve healthy elderly subjects aged 60 years and above were participated in this study. The test and retest repeatability of postural sway measurements were performed twice with a 1-hour interval. For each subject was assess postural sway using Lord’s sway meter during standing on 4 sensory conditions for 30 seconds of each condition. The test-retest reliability of sway area was calculated using intraclass correlation coefficient. The MDC for each sway area was calculated to quantify clinical relevance. Results The test-retest reliability of sway area revealed good to excellent reliability ranged from 0.85 to 0.94. Standard error of measurement (SEM) and MDC ranged from 75 to 205 mm2 and 209 to 568 mm2, respectively. Discussion and Conclusion Our findings reveal that sway area in different sensory conditions could be used in assessment of postural stability in elderly subjects. SEM and MDC of sway area increased when subjects were asked to close their eyes and on foam surface. The sway meter is a reliable tool for assessing postural stability in clinical setting.

Purpose: This study aimed (1) to evaluate the test–retest reliability of a new agility test among children and (2) to determine the physical performance and anthropometric variables that may influence agility performance in this population. Methods: For aim 1, participants (n = 34) completed the Ladder Agility Test (LAT) twice, with a 2-week interval between the first and second test occasions. For aim 2, participants (n = 125) were assessed on the LAT as well as other measures thought to be necessary for agility such as motor coordination, explosive power of the lower extremity, dynamic balance, age, and body mass index. Results: Intraclass correlation coefficient of the LAT total score was .94 (95% confidence interval, .88–.97). Cronbach alpha of .85 was found between the 4 test items. An R2 of .466 was found to represent the explained variance of the LAT total score by the predicting variables. Dynamic balance (2-legged side jumps) (P < .001), motor coordination (P < .01), and age (P < .06) were found to be the major predictors of the LAT total score. Conclusions: This study shows that the LAT is a reliable and valid field-based test that can be used to evaluate agility performance in children. Factors such as dynamic balance, motor coordination, and age may influence agility performance.

Test Retest Reliability

The Posture and Fine Motor Assessment of Infants (PFMAI) (Case-Smith, 1987) is a newly developed instrument for assessing the quality of motor function in infants. The test measures components of posture and fine motor control as they first develop. The purpose of this study was to support the test's reliability and validity. Interrater reliability, analyzed with intraclass correlation coefficients (ICCs), was high (.989 for total scores). Test-retest reliability, measured by ICCs, was .853 and .913 for the two test sections. The PFMAI demonstrated concurrent validity with the Peabody Developmental Motor Scales, Revised (Folio & Fewell, 1983) (correlations were .673 and .829 for the individual sections). Scores on the PFMAI were highly correlated with the infant's ages (.892 to .941); this finding provided one indication of construct validity.

Clinicians are in need of valid and objective measures of postural sway. Accelerometers have been shown to be suitable alternatives to expensive and stationary force plates. We evaluated the test-retest reliability and balance task discrimination capability of a new wireless triaxial accelerometer (YEI 3-Space Sensor). Four testing conditions (eyes open or closed, while on a firm or compliant surface) were used to progressively challenge the static balance of 20 healthy male (n = 8) and female (n = 12) older adults (mean age 81 ± 4.3 y). Subjects completed 2 blocks of three 30-second trials per condition. The accelerometer was positioned on the lower back to acquire mediolateral (M-L) and anterior-posterior (A-P) accelerations. Intraclass correlation coefficients were all good to excellent, with values ranging from .736 to .972 for trial-to-trial and from .760 to .954 for block-to-block. A significant stepwise increase in center of mass acceleration root mean square values was found across the 4 balance conditions (F[1.49, 28.26] = 39.54, P < .001). The new accelerometer exhibited good to excellent trial-to-trial and block-to-block reliability and was sensitive to differences in visual and surface conditions and acceleration axes.

ABSTRACT Objectives The 6-minute stepper test (6MST) is a submaximal test that requires little space to assess exercise capacity compared to the 6-minute walk test (6MWT). The study aims to investigate the test-retest reliability and convergent validity of 6MST and to compare physiological responses, dyspnea, fatigue perception with 6MST and 6MWT in patients with ankylosing spondylitis (AS). Methods To test the convergent validity of 6MST, 65 patients performed both 6MWT and 6MST on the first day and correlation between two tests were assessed with Pearson correlation test. In order to investigate the test-retest reliability of the 6MST, thirty-two of the 65 patients performed 6MST one week later and intraclass correlation coefficients (ICC) were calculated. Dyspnea and fatigue perception were analyzed with using Wilcoxon signed-rank test, physiological responses were analyzed using paired sample t-test. Results Excellent test-retest reliability was observed for 6MST (ICC: 0.988). There was a significant correlation between 6MST and 6MWT (r: 0.725, p<0.001). Dyspnea and leg fatigue perception were significantly higher in 6MST (p<0.05). Physiological responses and fatigue perception were similar in both 6MST and 6MWT (p>0.05). Conclusion This study demonstrated that the 6MST is reliable and valid method to evaluate exercise capacity in patients with AS. 6MST can be used to evaluate exercise capacity of patients with AS.

Objective: The main goal of this study was to exemplify the development of a measure of continuity of care (COC) from inpatients’ perspective. This measure is focused on several aspects related to physiotherapy.Methods: A cross-sectional self-report based psychometric study was carried out in a public hospital in southeast Spain. One hundred and fifty two patients with neurological and orthopaedic disorders who received rehabilitation care during stay at hospital were included in the study. A self-report questionnaire was used to examine experiences of patients related to the three types of COC, relational, management and informational continuity. The questionnaire also includes questions about sociodemographic characteristics, patient/therapist affiliation and trust with therapist. To examine reliability were used test-retest and internal consistency. For validation analysis, there were used convergent and known group strategies.Results: Of the 19 indicators included, 13 were selected to demonstrate adequate reliability and validity. From these indicators were generated three composite measures (Relational, management and COC index) and one individual measure (Informational continuity). Test-retest reliability indicated excellent agreement (intraclass correlation coefficient [ICC] > 0.75) for the three indexes. The range of Cronbach’s value was from 0.60 to 0.73. Total scores of all the indexes were moderately correlated with the satisfaction scale (r > 0.30). Regarding the known groups, all indexes scores were similar for men and woman. However, significant differences were found for management index and for relational index, based on trust with therapist and patient/therapist affiliation, respectively.Conclusions: The continuity self-reported measures is a valid and reliable method to assessing the COC in hospitalized patients receiving physiotherapy.
