Context: Total Motion Release® (TMR®) is a novel treatment paradigm used to restore asymmetries in the body (eg, pain, tightness, limited range of motion). Six primary movements, known as the Fab 6, are performed by the patient and scored using a 0 to 100 scale. Clinicians currently utilize the TMR® scale to modify treatment, assess patient progress, and measure treatment effectiveness; however, the reliability of the TMR® scale has not been determined. It is imperative to assess scale reliability and establish minimal detectable change (MDC) values to guide clinical practice. Objective: To assess the reliability of the TMR® scale and establish MDC values for each motion in healthy individuals in a group setting. Design: Retrospective analysis of group TMR® assessments. Setting: University classroom. Participants: A convenience sample of 61 students (23 males and 38 females; 25.48 [5.73] y), with (n = 31) and without (n = 30) previous exposure to TMR®. Intervention: The TMR® Fab 6 movements were tested at 2 time points, 2 hours apart. A clinician with previous training in TMR® led participant groups through both sessions while participants recorded individual motion scores using the 0 to 100 TMR® scale. Test–retest reliability was calculated using an intraclass correlation coefficient (2,1) for inexperienced, experienced, and combined student groups. Standard error of measurement and MDC values were also assessed for each intraclass correlation coefficient. Outcome Measure: Self-reported scores on the TMR® scale. Results: Test–retest reliability ranged from 0.57 to 0.95 across the Fab 6 movements, standard error of measurement values ranged from 4.85 to 11.77, and MDC values ranged from 13.45 to 32.62. Conclusion: The results indicate moderate to excellent reliability across the Fab 6 movements and a range of MDC values. Although this study is the first step in assessing the reliability of the TMR® scale for clinical practice, caution is warranted until further research is completed to establish reliability and MDC values of the TMR® scale in various settings to better guide patient care.

Purpose: To investigate the test–retest reliability and criterion validity of the isometric horizontal push test (IHPT), a newly designed test that selectively measures the horizontal component of maximal isometric force. Methods: Twenty-four active males with ≥3 years of resistance training experience performed 2 testing sessions of the IHPT, separated by 3 to 4 days of rest. In each session, subjects performed 3 maximal trials of the IHPT with 3 minutes of rest between them. The peak force outputs were collected simultaneously using a strain gauge and the criterion equipment consisting of a floor-embedded force plate. Results: The test–retest reliability of peak force values was nearly perfect (intraclass correlation coefficient = ∼.99). Bland–Altman analysis showed excellent agreement between days with nearly no bias for strain gauge 1.2 N (95% confidence interval [CI], −3 to 6 N) and force plate 0.8 N (95% CI, −4 to 6 N). A nearly perfect correlation was observed between the strain gauge and force plate (r = .98, P < .001), with a small bias of 8 N (95% CI, 1.2 to 15 N) in favor of the force plate. The sensitivity of the IHPT was also good, with smallest worthwhile change greater than standard error of measurement for both the strain gauge (smallest worthwhile change: 29 N; standard error of measurement: 17 N; 95% CI, 14 to 20 N) and the force plate (smallest worthwhile change: 29 N; standard error of measurement: 18 N; 95% CI, 14 to 19 N) devices. Conclusions: The high degree of validity, reliability, and sensitivity of the IHPT, coupled with its affordability, portability, ease of use, and time efficacy, point to the potential of the test for assessment and monitoring purposes.

AbstractIn this study, the test-retest-reliability as one aspect of reliability of metamorphopsia measurements using a computer-based measuring method was determined in patients with macular diseases. Metamorphopsia amplitude, position, and area were quantified using AMD – A Metamorphopsia Detector software (app4eyes GmbH & Co. KG, Germany) in patients with diabetic, myopic, or uveitic macular edema, intermediate or neovascular age-associated macular degeneration, epiretinal membrane, vitelliform maculopathy, Irvine-Gass syndrome, or macular edema due to venous retinal occlusion. The intraclass correlation coefficient (ICC) was calculated in order to determine the repeatability of two repeated measurements and was used as an indicator of the reliability of the measurements. In this study, metamorphopsia measurements were conducted on 36 eyes with macular diseases. Metamorphopsia measurements made using AMD – A Metamorphopsia Detector software were highly reliable and repeatable in patients with maculopathies. The intraclass correlation coefficient of all indices was excellent (0.95 – 0.97). For diseases of the vitreoretinal interface or macular diseases with intra- or subretinal edema, this metamorphopsia measurement represents a supplement for visual function testing in the clinic, as well as in clinical studies.

Objective: To evaluate the reliability and validity of the Thai version of the Carolinas Comfort Scale (CCS) to measure health-related quality of life (HRQoL) in post-hernia repaired patients. Materials and Methods: Three hundred twenty-eight patients that underwent the inguinal hernia repair procedure in Vajira Hospital were recruited in the present study. The Thai version of CCS (TCCS) was performed entirely by the patient, and the test-retest reliability was conducted at a 2-week interval. Results: The TCCS’s internal consistency reliability was excellent (Cronbach’s alpha 0.89). The inter-rater reliability was found to agree with the intraclass correlation coefficient of 0.90. The test-retest reliability over two weeks was high, with an intraclass correlation coefficient of 0.92. Conclusion: The Thai version of CCS was found to have adequate reliability and validity and could be used to measure HRQoL in Thai patients that undergo inguinal hernia repair. Keywords: Reliability; Validity; Carolinas Comfort Scale; Thai version

This study aimed to evaluate the test–retest reliability of soccer skill tests belonging to the F-MARC test battery. To avoid bias during talent identification and development, coaches and scouts should be using reliable tests for assessing soccer-specific skills in young male players. Fifty-two U-14 outfield male soccer players performed F-MARC soccer skill tests on two occasions, separated by 7 days. After familiarization, we administered two trial sessions of five skill tests: speed dribbling, juggling, shooting, passing, and heading. We assessed absolute reliability by expressing the standard error of measurement as a coefficient of variation with 95% limits of agreement, and we assessed relative reliability with the intraclass correlation coefficient and with Pearson’s correlation ( r). The results demonstrated satisfactory relative and absolute reliability for speed dribbling, right foot juggling, short passing, shooting a dead ball right, shooting from a pass, heading in front, and heading right. However, reliability values for left foot juggling, chest-head-foot juggling, head-left-foot-right foot-chest-head juggling, long pass, and shooting a dead ball left tests were not strong enough to suggest their usage by coaches in training or sport scientists in research.

Abstract Addressing physical activity (PA) barriers is an essential component of increasing PA among the 56-73% of community-dwelling adults 50 years and older who are not performing the recommended 150 minutes of moderate-to-vigorous PA. As there is no feasible, multi-factorial tool to assess PA barriers among this population, we developed and validated a PA barrier assessment tool called the Inventory of Physical Activity Barriers (IPAB). We collected cross-sectional data on 503 adults (mean age 70.1), with 79 participants completing the scale twice for test-retest reliability and 64 completing a cross-over design examining the ability to use two administration formats interchangeably. Our analyses consisted of exploratory and confirmatory factor analysis, Cronbach alpha, intraclass correlation coefficient, Bland-Altman Plot, and t-tests. Using factor analysis, we identified and confirmed an eight-factor solution consisting of 27 items. The 27-item IPAB is internally consistent (alpha= 0.91), has a high test-retest reliability (intraclass correlation coefficient=0.99), and can differentiate between individuals who meet the recommended levels of PA and those who do not (p &lt; 0.001). The IPAB scores ranged between 1.00-3.11 for the paper format (mean=1.78) and 1.07-3.48 for the electronic format (mean=1.78), with no statistical difference between the paper and electronic administration formats (p=0.94), resulting in the conclusion that the two administration formats can be used interchangeably. Participant feedback illustrates that the IPAB is easy to use, has clear instruction, and is an appropriate length. The newly validated IPAB scale can be used to develop individualized PA interventions that address PA barriers among patients 50 years and older.

CONTEXT: Epidemiological studies of the validity and reliability of self-reported information on important risk factors for non-communicable chronic diseases are scarce in Brazil. OBJECTIVE: We evaluated the test-retest reliability of information overall and stratified by gender, age and education on active and passive smoking, alcohol intake and aspects of dietary habits. TYPE OF STUDY: Test-retest reliability. SETTING: Universidade do Estado do Rio de Janeiro, Rio de Janeiro, Brazil. PARTICIPANTS: 192 University employees. PROCEDURES: Self-administered questionnaires were completed on two occasions, two weeks apart. MAIN MEASUREMENTS: Kappa Statistics; Intraclass Correlation Coefficient. RESULTS: Information on smoking status and pack-years smoked had almost perfect levels of agreement, respectively, kappa = 0.97 (95% CI, 0.92-1.00), and intraclass correlation coefficient = 0.93 (CI 95%, 0.89-0.96). Characteristics of alcohol intake yielded substantial levels of agreement (kappa ranging from 0.62 to 0.69). The reproducibility of the information on dietary habits varied from 0.67 to 0.79 (kappa). No clear-cut patterns could be identified comparing information by age or gender. There was a slight tendency towards greater reliability among people with higher levels of education. CONCLUSION: The reproducibility of information on smoking, drinking, and dietary patterns ranged from substantial to excellent, as investigated in the Pró-Saúde Study, a longitudinal investigation recently launched in Rio de Janeiro.

Abstract BACKGROUND: Because navigated transcranial magnetic stimulation (nTMS) is increasingly used in neurosurgical research, interpretation of its results is of utmost importance. OBJECTIVE: To evaluate the test-retest reliability of nTMS. METHODS: Twelve healthy participants underwent nTMS at 2 different sessions separated by 10.3 ± 9.6 days. Investigated parameters included resting motor thresholds, hotspots, and centers of gravity calculated for the first dorsal interosseous, abductor pollicis brevis, extensor digitorum, tibial anterior, and abductor hallucis muscles. RESULTS: Excellent reliability of resting motor thresholds was observed. Hotspots and centers of gravity showed moderate to excellent repeatability along the anteroposterior axis (intraclass correlation coefficient, 0.54-0.89), whereas the x coordinate presented mainly poor to moderate stability (intraclass correlation coefficient, 0.11-0.89). Movement of centers of gravity over sessions was 0.57 ± 0.32 cm, and hotspots laid 0.79 ± 0.47 cm apart. Calculation of coefficient of variation revealed high reliability of investigated parameters in upper extremities; in lower extremity muscles, high variation across sessions was observed. CONCLUSION: nTMS can be considered a reliable tool, thus opening new fields of noninvasive investigations in neurosurgery. The results presented here should be considered in the interpretation of individual nTMS results.
