Background: Under dual-task (DT), functional mobility and balance testing can detect balance and mobility problems in activities of daily living, especially in situations that cannot be identified under single-task conditions. Objective: Determine the test-retest reliability and concurrent validity of the Four Square Step Test (FSST) under DT conditions for people with total knee arthroplasty (TKA). Method: A total of 30 patients with TKA participated in this research, and patients were tested with the FSST under DT conditions. In addition, concurrent validity of the dual-task FSST was calculated using Timed Up and Go (TUG) under the single-task condition and Hospital for Special Surgery (HSS) Knee Score. Patients performed two FSST trials on the same day under DT conditions. Results: The intraclass correlation coefficients (ICC2,1) two-way random effects model, and minimal detectable changes with 95% confidence intervals (MDC95) values of the FSST under DT conditions were.97 and 3.43, respectively. The Pearson's correlation coefficient of the FSST with the TUG and HSS was.65 and −.40, respectively. Conclusion: The FSST has been found to be a reliable and valid clinical assessment tool for dynamic balance under DT conditions in patients with TKA. For identify balance disorders in daily life at early points, clinicians and researchers can use the FSST under DT conditions in TKA.

Background: Assessing reflective performance in medical students is a crucial initial step in devising effective educational strategies for its enhancement. Current reflection scales in Iran fall short, primarily because they do not adequately address students' willingness and inclination to engage in reflective practices. This study aimed to test psychometric properties of Reflective Performance Questionnaire (RPQ) among medical sciences students in Iran. Methods: This cross-sectional study was conducted in Tabriz University of Medical Sciences students (n=245). The RPQ underwent translation from English to Persian through a translation and backtranslation process. The psychometric properties of the RPQ were done by using face, content, and construct validity, and reliability. The construct validity was done using Exploratory Factor Analysis (EFA) on 245 students. The reliability of the RPQ was also checked with two approaches of internal consistency and stability. Results: The content validity indices, namely Content Validity Index (CVI) and Content Validity Ratio (CVR), were deemed satisfactory with values of 0.93 and 0.74, respectively. The EFA revealed a single factor containing 40 items explained more than 33% of the total observed variance. The reliability test revealed that the Cronbach's alpha coefficient (equal to 0.89) and the Intra-class Correlation Coefficient (ICC) indicated satisfactory internal consistency equal to 0.89 (95%CI=0.87-0.91) for the tool. Conclusion: This study confirmed that the Persian version of the "Reflective performance Scale" is a reliable and valid instrument to evaluate reflective performance in medical students within Iran. The structure of the dimensions obtained in this study was consistent with the structure of the original scale. [ABSTRACT FROM AUTHOR]

Background: Temporomandibular Disorders (TMDs) are a group of disorders associated with masticatory dysfunction. TMDs are usually diagnosed late which leads to complicated treatments. Early diagnosis and treatment of TMDs are essential. Methods: A valid and reliable version of Fonseca's Anamnestic Index (FAI) was prepared in Persian from the English version. It was used to assess TMD in 350 patients. Clinical signs of TMD were also recorded based on examination. Results: FAI scores showed 161(46%) people had TMD. There was no significant difference between occlusion classes in terms of the frequency of TMD. There was no significant difference between the mean maximum mouth opening and severity of TMD. Conclusion: In this study the validity and reliability of the FAI in Persian language, as a simple tool for TMD screening in health centers, was confirmed. Based on results, there is a relationship between clinical findings and the severity of TMD by using FAI and it can be used for screening TMD patients. [ABSTRACT FROM AUTHOR]

Background: The modified Fresno test was developed to assess knowledge and skills related to evidence-based practice among physical therapists and students, however no Chinese version is available. Therefore, the aim of this study was to cross-culturally adapt the English version of the modified Fresno test into Chinese and to evaluate its validity and reliability. Methods: This was a cross-sectional validation study. During Phase 1 cross-cultural adaptation, forward translation, synthesis, back-translation, expert review, and prefinal test were carried out. Content validity was analyzed. During Phase 2 validation, two groups representing different levels of evidence-based practice competence completed the tests twice, two weeks apart. Known-group validity, internal consistency, and test-retest reliability were analyzed. Results: Phase 1: According to the expert review, the Chinese version of the modified Fresno test demonstrated good content validity (item-level content validity index = 0.93 to 1.0; scale-level content validity index = 0.99). Phase 2: The expert group scored (115.3 ± 36.2) significantly higher than the novice group did (79.7 ± 25.8) for the entire test (p = 0.01), suggesting good known-group validity. However, the superior performance of the expert group over the novice group was not consistently found across all the questions on the test. In addition, the internal consistency was good (Cronbach's α = 0.96) and the test-retest reliability (ICC2,1 = 0.89, 95% CI = 0.81 to 0.94) was good to excellent. Conclusions: The Chinese version of the modified Fresno test is a valid and reliable tool for objectively assessing evidence-based practice knowledge and skills in Chinese-speaking physical therapists and students.

Objective Methods Results Conclusion To translate and cross‐culturally adapt the Headache Disability Inventory (HDI) into Italian and study its reliability and validity.A total of 132 participants with primary and secondary headaches were included. The translation was performed following international guidelines with forward and back translation procedures. Structural validity, internal consistency, test–retest reliability, measurement error, and construct validity were studied. Test–retest reliability and measurement error were tested on a subsample of 32 participants.The cross‐cultural adaptation into Italian was performed without issues. Confirmatory factor analysis supports the structural validity partially (comparative fit index = 0.963; Tucker–Lewis index = 0.959; root mean square error of approximation = 0.051; standardized root mean square residual = 0.084), showing a two‐factor structure (i.e., emotional and functional). Each subscale presented high internal consistency (α = 0.87 and 0.87 for the emotional and functional subscales, respectively), excellent and good test–retest reliability (intraclass correlation coefficient = 0.93 and 0.88 for the emotional and functional subscales, respectively), and acceptable measurement error (standard error of the measurement [SEM] = 3.6 points, minimal detectable change [MDC] = 10.0 points for the emotional subscale; SEM = 3.8 points, MDC = 10.7 points for the functional subscale). Construct validity was satisfactory for the emotional subscale and moderate for the functional subscale, as 85.7% (6/7) and 57.1% (4/7) of a priori hypotheses were met, respectively.The HDI was successfully translated into Italian and has acceptable psychometric properties. The Italian version of the HDI can be used in daily clinical practice and research to assess the functional and emotional impact of primary and secondary headaches. Further research should study other psychometric properties (i.e., content validity, responsiveness, and reliability in a larger sample). [ABSTRACT FROM AUTHOR]

Objectives: The current study aimed to develop a valid and reliable questionnaire in both English and Persian to assess dental patients' knowledge and attitude during the COVID19 outbreak. Materials and Methods: Through a comprehensive literature review, we designed the primary questionnaire in English and then translated it into Persian. The questionnaire consisted of six sections covering background information, knowledge of emergency dental treatments, transmission routes of disease, required preparation, source of information, and attitude. To evaluate the validity of the questionnaire, the researchers obtained expert opinions using the Item Content Validity Index (I-CVI) and Scale Content Validity Index (S-CVI/Ave). They distributed online versions of the questionnaire to a total of 60 English-speaking adults in Nigeria and the United States, and 60 Persian-speaking adults in Iran to measure its reliability using Cronbach's alpha. Results: I-CVI score, S-CVI/Ave, and Cronbach’s alpha of the questionnaire ranged from 0.29-1, 0.62-0.99, and 41.1-87.6%, respectively. After reviewing the scores and comments received on each item, taking into account the opinions of the research team, a decision was made to remove, merge, modify, or retain certain items. This led to a final version of the questionnaire consisting of nine questions in the background section and 46 items in the remaining five sections. Conclusion: Overall, the developed questionnaire appears to be valid and reliable for assessing the knowledge and attitude of dental patients toward COVID-19 in dental settings. It can potentially serve as an appropriate scale in future infectious disease epidemics across diverse populations. [ABSTRACT FROM AUTHOR]

AbstractPurposeMethodsResultsConclusions\nIMPLICATIONS FOR REHABILITATIONTo evaluate inter- and intrarater reliability, of the Eating and Drinking Ability Classification System (EDACS) for children and adults with cerebral palsy (CP) in Sweden.Four speech and language pathologists rated EDACS from videos of 30 individuals with CP, 3 to 62 years, (mean 21 y, 10 m, SD 18 y, 6 m), six at each level of the Gross Motor Function Classification System (GMFCS). Inter- and intrarater reliability were estimated using Intraclass Correlation Coefficient (ICC) with 95% confidence interval.Interrater reliability was excellent, ICC 0.98 (95% CI 0.95–0.99) for EDACS levels I–V and ICC 1 for need for support, as was intrarater reliability, ICC 0.97 (95% CI 0.93–0.98) for EDACS levels I–V and ICC 0.99 (95% CI 0.99–1) for need for support.When rated by speech and language pathologists, EDACS shows excellent inter- and intrarater reliability for children and adults with CP. EDACS can identify eating and drinking ability and need for support in individuals at all GMFCS levels.When rated by speech and language pathologists, Eating and Drinking Ability Classification System shows excellent inter- and intrarater reliability for children and adults with cerebral palsy in Sweden.Eating and drinking ability and need for support differ between individuals at Gross Motor Function Classification System levels I to V.When rated by speech and language pathologists, Eating and Drinking Ability Classification System shows excellent inter- and intrarater reliability for children and adults with cerebral palsy in Sweden.Eating and drinking ability and need for support differ between individuals at Gross Motor Function Classification System levels I to V.

Objective: In cone-beam computed tomography (CBCT), voxel resolution and size directly affect image quality. This study aimed to analyze the effect of voxel resolution on the linear and volumetric measurements of tooth and pulp in three-dimensional images obtained with different voxel sizes and to test the repeatability of these measurements. Materials and methods: CBCT images of 30 extracted single-rooted permanent teeth were obtained using 3 different voxel sizes (0.1-, 0.2-, 0.4-mm). Two observers performed volumetric and linear measurements of pulp and teeth using semi-automatic segmentation. The data were analyzed using descriptive and nonparametric tests. For interobserver reliability, the Wilcoxon signed test and Kendall's tau correlation coefficient were used. The intraobserver repeatability was analyzed using the intraclass correlation coefficient. The significance level was set at 0.05. Results: Friedman test showed no significant difference (p > 0.05) in volumetric measurements between different voxels in one of the observers, but a significant difference was found in the pulp volume measurement in the other (p < 0.001). The voxel sizes did not affect the linear measurements of both observers (p > 0.05). The interclass reliability (Wilcoxon signed test and Kendall's tau correlation coefficient) and intraobserver repeatability (intraclass correlation coefficient) decreased as the voxel size increased for linear and volumetric measurements of tooth and pulp (p > 0.05). While the values indicated "good" and "excellent" reliability for all parameters measured on the 0.1- and 0.2-mm voxels, a few "moderate" reliability values were found on the 0.4-mm voxel. Conclusion: Voxel sizes of 0.1- and 0.2-mm did not significantly affect linear and volumetric tooth measurements. When the voxel size increased, the reliability and repeatability decreased. To increase measurement reliability, the voxel size should be as small as possible. [ABSTRACT FROM AUTHOR]

Objectives The benefits of liquid-based cytology (LBC) in routine cervical cancer screening are often associated with the availability of instrumented platforms and economic considerations. A low-cost alternative to LBC in low-volume settings remains an unmet need. Methods A multisite evaluation of the BD SurePath (SurePath) LBC Direct to Slide (DTS) method was conducted. The DTS preparations were evaluated across 3 sites. Cytology features for DTS preparation included predetermined thresholds for total cellularity, cell distribution, cellular preservation, and stain quality. Rare event detection was evaluated using SiHa cells spiked into pools from negative cytology specimens. Concordance between Bethesda classification results was evaluated for SurePath LBC and DTS methods using routinely collected SurePath specimens in a split-sample study design. Results The DTS specimens met criteria for total cellularity, cell distribution, cellular preservation, and stain quality in more than 98% of all cases. Rare event detection was observed with an average detection of 5 SiHa cells per 2 mL of specimen. Concordant cervical cytology classifications were observed between SurePath LBC and DTS methods. Conclusions The results demonstrate that the DTS process is suitable for routine cervical cytology evaluation. The procedure is reproducible and detected abnormal cervical cells in concordance with standard SurePath LBC preparation. [ABSTRACT FROM AUTHOR]

To test the reliability of the VO 2 Master Pro and to compare it to the Cosmed Quark. Eight recreational cyclists participated in two different trials which consisted of graded cycling exercise stages at 50%, 70%, and 85% of their critical power. The VO 2 Master Pro was used during the first visit, while both the VO 2 Master Pro and Cosmed Quark were used during the second visit. Equivalence testing of the trials was done by TOST analysis while test of difference was done by ANOVA. The results indicated equivalence of the VO 2 Master Pro in the measurement of VO 2 (35.1 ± 10.4 mL·kg−1·min−1 vs. 35.4 ± 10.2 mL·kg−1·min−1) and V E (72.4 ± 20.5 L·min−1 vs 73.8 ± 22.3 L·min−1) across repeated visits indicating good reliability of the device. However, neither significant equivalence nor difference was detected when comparing the VO 2 Master Pro to the Cosmed Quark across the same variables indicating that the two devices were similar to each other.

BACKGROUND: Isometric maximal voluntary force (IMVF) is essential for individuals' health and physical performance. Therefore, there is a need for valid and reliable devices to assess IMVF. OBJECTIVE: To determine the validity and reliability of the Valkyria Trainer Balance® portable force platform in its isometric mode. METHODS: Fifty-eight physically healthy individuals (30 men and 28 women) participated in the study. A repeated measures design was used to compare the inter-day test-retest reliability of peak force. The validity of the Valkyria Trainer Balance® force platform was determined by comparing the peak force with the ArtOficio® force platform. The analysis consisted of the intraclass correlation coefficient (ICC), standard error of measurement (SEM), and coefficient of variation (CV). A CV ⩽ 10% and ICC ⩾ 0.80 were considered acceptable reliability, while a ⩽ 5% and ICC ⩾ 0.90 were regarded as high reliability. RESULTS: CV the peak force showed high test-retest inter-day reliability (CV = 4.3% and ICC = 0.99). When comparing both force platforms, there was a 1.1% difference between the two devices. CONCLUSIONS: The results of this study demonstrate that the Valkyria Trainer Balance® force platform is valid and reliable for assessing IMVF in physically healthy individuals.

Background: Heart failure (HF) patients can experience poor appetite and intense thirst. The Thirst Distress Scale for HF (TDS-HF) and the Simplified Nutritional Appetite Questionnaire (SNAQ) are tools used to assess these symptoms. However, these questionnaires are not currently available in Thai. Aims: To translate the TDS-HF and SNAQ into the Thai language and to evaluate the reliability and validity of these translated instruments. Methods: The TDS-HF and the SNAQ were translated from English to Thai using a forward–backward method. Their face and content validity, their internal consistency and test–retest reliability, were assessed with a sample of 20 HF patients recruited from a single supra-tertiary hospital in Thailand. Results: Participants reported that the TDS-HF and the SNAQ had face validity. The content validity was assessed as adequate by the expert panel. The Cronbach's alphas of the TDS-HF and the SNAQ were 0.91 and 0.71, respectively. The intraclass correlation coefficients of the TDS-HF and the SNAQ were 0.91 and 0.91, respectively. Conclusions: The Thai versions of the TDS-HF and the SNAQ demonstrate adequate validity and reliability. These tools hold significant potential for supporting clinical practice, particularly for nurses involved in HF management by helping to assess thirst and appetite effectively.

Background: Grip strength is widely used as a surrogate parameter for functional status. The current gold standard, the JAMAR® Hydraulic Dynamometer (JAMAR® Hydraulic), presents challenges for individuals with painful finger joints or low grip strength. Therefore, the objective of this observational study was to assess comparability across the JAMAR® Smart, the Martin Vigorimeter and the gold standard. Additionally, the intrasubject and intersession reliability of all three devices were examined, which are essential for quality control before generating normative data. Methods: Forty healthy participants (aged 37.0 ± 11.3 years) were included, and a subset of 20 participants was randomly selected for retesting. Grip strength testing involved five attempts per measurement device. Results: Intrasubject reliability was excellent (ICC3,1: 0.91–0.97), and a strong correlation (ICC3,1: 0.90–0.98) was found between the first attempt and the best of five as well as between the best of two or three attempts and the best of five, demonstrating robust reliability across multiple measures. Intersession reliability was good to excellent (ICC3,1: 0.85–0.97) across all three devices, which was confirmed by Bland–Altman analysis. The PCC (r) revealed moderate to very strong agreement with the current gold standard JAMAR® Hydraulic (r = 0.68–0.98), with increased differences between the Martin Vigorimeter and the JAMAR® Hydraulic measurements, particularly at low and high values. Conclusions: The proposed devices are suitable for test-retest analysis with 2–3 attempts. Despite high correlations between all three devices, the diverging levels of agreement between the Martin Vigorimeter and the established gold standard warrant caution against using these devices interchangeably.

Background/Objectives: The extensive range of instruments designed for evaluating functional performance (FP) in chronic respiratory diseases (CRD) other than chronic obstructive pulmonary disease (COPD) presents a challenge in selecting the most appropriate one. Therefore, this systematic review aimed to summarise FP instruments, their measurement properties, their minimum clinically important differences, and their associations with CRD course-related events or prognosis in non-COPD CRD. Methods: Studies employing patient-reported or performance-based instruments to assess FP in non-COPD CRD were systematically identified in the PubMed, PEDro, Embase, and Cochrane Library databases. COPD-exclusive studies or those solely reporting exercise capacity tests were excluded. Examination focused on measurement properties and associations with CRD course-related events or prognosis. The risk of bias was evaluated using the COSMIN, Downs and Black, and PEDro checklists based on the study design. Results: A total of 216 studies across seven CRD categories [asthma, bronchiectasis, cystic fibrosis, interstitial lung disease (ILD), pulmonary arterial hypertension (PAH), pre-/post-lung-transplantation] from various study types were included. Thirty-three instruments were identified, with the SF-36 questionnaire's physical function domain being the most commonly used patient-reported tool. The 1 min sit-to-stand test was the most extensively studied performance-based measure, with its measurement properties frequently reported in non-COPD CRD studies. Associations with events were infrequently documented, primarily in ILD and PAH studies related to mortality. Conclusions: Despite the prevalent use of FP instruments, limited information exists concerning their measurement properties and clinical implications. This review furnishes a concise summary of available evidence, aiding informed clinical decisions when selecting FP tools for non-COPD CRD. [ABSTRACT FROM AUTHOR]

Background/Objectives: Despite the increasing use of chromatic intraoral scanners, color determination is often performed visually, offering poor reliability and validity. In this study, we aimed to compare the reliability and validity of the tooth shade determination tool of an intraoral scanner (Trios3 Color) with that of two dental spectrophotometers (VITA Easyshade Advance 4.0 and SpectroShade Micro) and with visual determination using the VITA 3D-Master shade guide. Methods: In vivo tooth shade determination was performed on 33 participants using positioning splints for the right central incisor. Repeated measurements assessed the reliability in determining the percentage agreement with VITA 3D-Master shades. VITA Easyshade measurements were used as reference values for validity. The metric value Delta E (ΔE) in the International Commission on Illumination L*a*b* color space was compared to the reference, with ΔE greater than 1 indicating visible differences and a maximum value of ΔE 6.8 being clinically acceptable. Results: The reliabilities of VITA Easyshade, the intraoral scanner, and SpectroShade Micro were 75.8%, 87.9%, and 89.9%, respectively. The visual method had an agreement rate of 20.6%. Validity values, compared with the reference value, were ΔE 3.8 (clinically acceptable), 8.3, and 7.4 (the latter two both being clinically unacceptable) for the intraoral scanner, area-measuring device, and visual method, respectively. Conclusions: The intraoral scanner is a reliable and valid tool for tooth shade determination and is superior to the visual method in both aspects. [ABSTRACT FROM AUTHOR]

Purpose: To evaluate the data on the psychometric properties of the Neck Disability Index (NDI). Materials and methods: Medline, Embase, PsychINFO, Web of Science, and Scopus were searched in April 2023. The random effects meta-analysis was conducted when possible. Results: Of 492 identified records, 79 were included. 70 studies were considered to be of low risk of systematic bias. Alpha was >0.81. Pooled test-retest intraclass correlation coefficient was 0.91 (95% CI 0.90–0.93). The NDI correlations with pain rating scales varied from 0.38 to 0.89. 13 studies found the NDI to be unidimensional and 15 – two- or three-dimensional. The minimal detectable change varied from 3% to 27% and minimal clinically important difference from 5% to 33%. Pooled area under the curve was 0.74 (95% CI 0.68–0.80). Most studies have not detected floor or ceiling effect. Sex-related differential item functioning has been present in one study. Conclusions: The NDI demonstrated good internal consistency and test-retest reliability without floor or ceiling effect. In most situations, the NDI could be considered a unidimensional scale. The NDI well correlated with the common scales of pain and disability. The minimal clinically important difference and minimal detectable change were around 15% (7.5/50 points). IMPLICATIONS FOR REHABILITATION: Based on the 79 observational studies of mostly low risk of systematic bias, the Neck Disability Index demonstrated overall good psychometric properties The Neck Disability Index is a reliable scale to assess the severity of disability caused by neck pain of different musculoskeletal aetiology [ABSTRACT FROM AUTHOR]

Purpose: To investigate the test-retest reliability and construct validity of the LCADL scale applied via online form in individuals after hospitalization for COVID-19. Methods: Methodological study. After hospitalization for COVID-19 individuals completed the LCADL via online form at two separate times. They also answered the post-COVID-19 Functional Status Scale (PCFS), dyspnea, fatigue, and health perception scales, modified Medical Research Council (MRCm), Short Form Health Survey 36 (SF-36). Hospitalization data were collected from the individual's medical record. Results: 104 individuals participated in the study (57 men, 45.2 ± 11.9 years). The LCADL showed moderately to high test-retest reliability (ICC: 0.73–0.86; p < 0.001), there was no difference in scores between test and retest (p > 0.05), the mean difference between the applications was smaller than the standard error of measurement and the internal consistency was adequate (Cronbach's α = 0.70–0.94). In addition, it demonstrated adequate construct validity, showing correlations with PCFS, dyspnea perception, fatigue and health scales, mMRC, SF-36, and length of stay in the Intensive Care Unit (p < 0.05). The LCADL as percentage of the total score presented a significant floor effect (25%). Conclusion: The LCADL applied online was reliable and valid for assessing limitations due to dyspnea in ADL in individuals after hospitalization for COVID-19. IMPLICATIONS FOR REHABILITATION: The London Chest Activity of Daily Living Scale applied online is a method of evaluation of dyspnea-related ADL limitations that is valid and reliable after hospitalization for COVID-19 and can be used both in the telerehabilitation environment and in-person rehabilitation; The online form provides a more sustainable means of data storage, since no paper is needed, and saves time during in-person rehabilitation.

Objective The purpose of this study was to validate a maximum inspiratory pressure (MIP) test protocol based on the principles of the 1-repetition maximum (1RM) test, assess its test-retest reliability, and establish minimal detectable change (MDC) in individuals with chronic obstructive pulmonary disease (COPD). Methods Forty-nine individuals with COPD were included in the study, of whom 44 individuals attended 2 appointments separated by 7 to 10 days for test-retest reliability. The MIP test was performed using a threshold valve device (1RM-based protocol) and the digital manometer (reference test). The 1RM-based protocol consisted of an incremental phase (inspiratory load increase [10 cm H2O] to achieve respiratory failure) and an approach phase (load halfway between the lowest failed attempt and the last valid attempt was prescribed). Results The concurrent validity of the 1RM-based protocol for the MIP test was good with respect to the reference test (day 1, intraclass correlation coefficient [ICC] = 0.81; day 2, ICC = 0.85). The test-retest reliability was excellent (ICC = 0.92), with a standard error of measurement of 6.3 cm H2O and a MDC of 17.5 cm H2O. Conclusion This study validated a new 1RM-based protocol for the MIP test using an inspiratory muscle training (IMT) device in individuals with COPD, showing good concurrent validity compared with the reference test, as well as excellent test-retest reliability. The MDC reported can be interpreted and applied in the clinical setting. Impact There was a need for developing new, inexpensive, simple, and feasible methods for the MIP test. The validation of the 1RM-based protocol addresses this issue, allowing for the appropriate prescription of IMT, favoring its widespread use in people with COPD, and therefore improving their physical therapist care.

Background: With the increased interest in inter-recti distance measurement using ultrasound imaging in physiotherapy, there is a question of measurement reliability, and the importance of the examiner's experience. Purpose: The study aimed to investigate the reliability of inter-recti distance measurement in a DICOM viewer software by an experienced radiologist. For the measurement, the radiologist used linea alba images captured by two physiotherapists who were novice examiners. Methods: Ultrasound images were acquired by two novice examiners on repeated occasions 7 days apart (sessions A and B) in 28 nulliparous women at supraumbilical, umbilical, and infraumbilical locations along linea alba. Results: Excellent intra-examiner reliability of inter-recti distance measurements was shown at the supraumbilical and umbilical levels (ICC2,k = 0.941–0.983) with minimal detectable change (MDC95) ranging from 1.31 mm to 2.29 mm. Infraumbilical measurements had good to excellent reliability (ICC2,k = 0.894–0.972) with MDC95 ranging from 0.33 mm to 0.72 mm. Session A inter-examiner reliability was excellent for the mean measurements of two, three, four, and five images taken at each location (ICC2,k = 0.913–0.954) with MDC95 ranging from 0.47 mm to 2.96 mm. Session B inter-examiner reliability was excellent for the mean measurements of two, three, four, and five images taken at the supraumbilical and umbilical (ICC2,k = 0.94–0.98), MDC95 ranging from 1.38 mm to 2.58 mm and good (ICC2,k ≥ 0.81) with MDC95 ranging from 0.72 mm to 0.80 mm at the infraumbilical locations. Conclusion: Novice examiners were able to capture good-quality ultrasound images of the linea alba that allowed for good to excellent intra- and inter-examiner reliability. [ABSTRACT FROM AUTHOR]

Background: Inadequate daily oral hygiene care of dental prostheses could worsen general health of frail older people. The index of Augsburger and Elahi is often recommended to assess maxillary dental prosthesis plaque (DPP). Objective: To assess the reliability of an expanded and standardised DPP index of Augsburger and Elahi in trained and untrained examiners, and to determine the applicability of the index in community‐dwelling frail older people. Methods: Ten community‐dwelling frail older persons with complete and partial removable dental prostheses (RDPs) (mean ± SD age = 87.9 ± 8.4 years) participated. Seven persons were revisited after 3 months. The index was expanded with mandibular RDPs. Standardisation was achieved with a specially designed reference sheet. The RDPs were photographed after plaque colouring. Two trained examiners scored the photographs; thereafter, two untrained examiners. One trained examiner scored the photographs again after 3 weeks. Changes in DPP over the 3‐month period were assessed with Wilcoxon signed‐rank test. Inter‐ and intra‐examiner reliability was assessed with intraclass correlation coefficients (ICCs). Results: The DPP scores did not change significantly over time (Z = −0.594, p = 0.553). Inter‐examiner reliability was excellent in the trained examiners (ICC = 0.859–0.947), and fair‐to‐good in the untrained examiners (ICC = 0.671–0.703). Intra‐examiner reliability was excellent (ICC = 0.941–0.962). Conclusion: The proposed expansion and standardisation of the DPP index has an excellent inter‐ and intra‐examiner reliability when performed by trained examiners, and a fair‐to‐good inter‐examiner reliability by untrained examiners. Therefore, the index could be recommended for application in dental prostheses‐wearing older persons and could be useful for awareness and education of professional and informal caregivers and the older persons themselves.

Internal and external quality assurance materials often use highly processed matrixes. This can render the materials non-commutable. Monitoring laboratory methods with patient medians helps in identifying and correcting systematic errors that may affect diagnostic accuracy. The aim of the present study was to use HbA1c patient results for monitoring of method performance over time. Test HbA1c results from 2010 to 2022 was analyzed (n=722,553) regarding changes over time and seasonal variation. The HbA1c testing was initially performed on a Cobas 501 instrument using immunological detection but in May 2017 the method was replaced by capillary electrophoresis on Capillarys 3 Tera. There was a steady decrease in HbA1c values. From 2011 to 2021 the decrease was for 0.10 percentile 6.6 %, lower quartile 7.9 %, median 10.2 %, mean values 9 %, upper quartile 11.2 %, and 0.90 percentile 9.3 %. No clear shift in HbA1c levels was observed due to the shift in methods. The median HbA1c values per month was approximately 44 mmol/mol (6.2 %, DCCT/NGSP). The only month with a median HbA1c that differed by more than 1 mmol/mol was July with a median value of 42 mmol/mol (6.0 %). The patient data showed a similar decrease as in the National Diabetes Register which indicates that the method is stable over time without any sudden changes and that the seasonal variation is low. The continuous decrease in HbA1c values over time is most likely to a shift towards earlier detection of patient with diabetes and improved treatment. [ABSTRACT FROM AUTHOR]

Objective: T2-relaxometry could differentiate between physiological and haemorrhagic joint effusion (≥ 5% blood) in vitro. Are quantitative T2-relaxation time measurements of synovial fluid feasible and reproducible in vivo in clinically bleed-free joints of men with haemophilia? Materials and methods: In this cross-sectional study, we measured T2-relaxation times of synovial fluid in clinically bleed-free ankles, knees or elbows of men with severe haemophilia A using a T2-mapping sequence (duration ≤ 7 min) at 3 Tesla MRI. Manual and circular regions of interest (ROI) were drawn in the synovial fluid of each joint by two independent observers to measure T2-relaxation times. Measurement feasibility was expressed as the success rate of the measurements by both observers. The interobserver and intraobserver reproducibility of the measurements were evaluated by the intraclass correlation coefficient of absolute agreement (ICC) and the limits of agreement (LoA) from Bland Altman analysis. Results: We evaluated 39 clinically bleed-free joints (11 ankles, 12 knees, 16 elbows) of 39 men (median age, 24 years; range 17–33) with severe haemophilia A. The success rate of the T2-measurements was ≥ 90%. Interobserver reliability was good to excellent (manual ROI: ICC = 0.92, 95% CI 0.76–0.97; circular ROI: ICC = 0.82, 95% CI 0.66–0.91) and interobserver agreement was adequate (manual ROI: LoA = 71 ms; circular ROI: LoA = 146 ms). Intraobserver reliability was good to excellent (manual ROI: ICC = 0.78, 95% CI − 0.06–0.94; circular RO: ICC = 0.99, 95% CI 0.98–0.99) and intraobserver agreement was good (manual ROI: LoA = 63 ms; circular ROI: LoA = 41 ms). Conclusion: T2-relaxometry of synovial fluid in haemophilia patients is feasible with good interobserver and intraobserver reproducibility. [ABSTRACT FROM AUTHOR]

Abstract Background The modified Fresno test was developed to assess knowledge and skills related to evidence-based practice among physical therapists and students, however no Chinese version is available. Therefore, the aim of this study was to cross-culturally adapt the English version of the modified Fresno test into Chinese and to evaluate its validity and reliability. Methods This was a cross-sectional validation study. During Phase 1 cross-cultural adaptation, forward translation, synthesis, back-translation, expert review, and prefinal test were carried out. Content validity was analyzed. During Phase 2 validation, two groups representing different levels of evidence-based practice competence completed the tests twice, two weeks apart. Known-group validity, internal consistency, and test-retest reliability were analyzed. Results Phase 1: According to the expert review, the Chinese version of the modified Fresno test demonstrated good content validity (item-level content validity index = 0.93 to 1.0; scale-level content validity index = 0.99). Phase 2: The expert group scored (115.3 ± 36.2) significantly higher than the novice group did (79.7 ± 25.8) for the entire test (p = 0.01), suggesting good known-group validity. However, the superior performance of the expert group over the novice group was not consistently found across all the questions on the test. In addition, the internal consistency was good (Cronbach’s α = 0.96) and the test-retest reliability (ICC2,1 = 0.89, 95% CI = 0.81 to 0.94) was good to excellent. Conclusions The Chinese version of the modified Fresno test is a valid and reliable tool for objectively assessing evidence-based practice knowledge and skills in Chinese-speaking physical therapists and students.

Summary: Purpose: This study aimed to adapt and validate the Korean version of the Caregiver Burden Questionnaire for Family Caregivers of Hemodialysis Patients, originally developed by Hejazi et al. in 2022, to ensure its applicability and validity in Korea. Methods: Using both online and offline approaches, this study included 230 family caregivers. Data analysis was performed with SPSS AMOS version 29.0 using the Korean version of the Caregiver Burden Questionnaire for Family Caregivers of Hemodialysis Patients and the Korean version of the Zarit Burden Interview as the primary instruments. Results: The findings confirmed the high content validity of the questionnaire (scale-level content validity index = .99), and confirmatory factor analysis established its construct validity. Convergent validity was confirmed with average variance extracted values ranging from .43 to .87, and composite reliability scores ranging from .80 to .91. A significant positive correlation with the Korean version of the Zarit Burden Interview (r = .81) demonstrated concurrent validity. The tool consists of 21 items across four factors on a 5-point Likert scale, exhibiting excellent internal consistency (Cronbach's α = .91) and good test-retest reliability (intraclass correlation coefficient = .79). Conclusion: This study validated a reliable instrument for assessing caregiver burden in families of hemodialysis patients in Korea. This tool accurately measures caregiver challenges and has the potential to enhance societal health and welfare.

Background This study aimed to develop an instrument for assessing physical functioning among adults aged 50 years or older living in the community. Methods Based on a review of various national health surveys and cohort studies, a 144-item bank was constructed for assessing physical functioning. Focus group interviews were conducted among adults aged 50 years or older to investigate their level of understanding of 60 selected items, followed by a pretest of the items on a nationally representative sample (n=508). The final 25-item questionnaire was tested on an independent sample (n=259) for validity and reliability based on classical test and item response theories. Predictive validity at the 6-month follow-up was tested in a separate sample (n=263). Results The newly developed Life Functioning (LF) scale assessed the dimensions of functional limitations, disabilities, and social activities. The scale satisfied a one-dimensionality assumption with good item fit and demonstrated criterion validity, construct validity, high internal consistency (Cronbach’s alpha=0.93), and test-retest reliability (intra-class correlation coefficient=0.84; 95% confidence interval, 0.76–0.89). The LF scale comprised 25 items with a total score ranging from 0 to 100. Higher scores indicated higher levels of functioning. The LF score was significantly associated with the Physical Functioning score at 6 months. Conclusion The LF scale was developed to assess the physical functioning of people in their late midlife or older. Future studies should test the instrument on a national sample and evaluate its application in diverse population subgroups.

Abstract Objective In cone-beam computed tomography (CBCT), voxel resolution and size directly affect image quality. This study aimed to analyze the effect of voxel resolution on the linear and volumetric measurements of tooth and pulp in three-dimensional images obtained with different voxel sizes and to test the repeatability of these measurements. Materials and methods CBCT images of 30 extracted single-rooted permanent teeth were obtained using 3 different voxel sizes (0.1-, 0.2-, 0.4-mm). Two observers performed volumetric and linear measurements of pulp and teeth using semi-automatic segmentation. The data were analyzed using descriptive and nonparametric tests. For interobserver reliability, the Wilcoxon signed test and Kendall’s tau correlation coefficient were used. The intraobserver repeatability was analyzed using the intraclass correlation coefficient. The significance level was set at 0.05. Results Friedman test showed no significant difference (p > 0.05) in volumetric measurements between different voxels in one of the observers, but a significant difference was found in the pulp volume measurement in the other (p 0.05). The interclass reliability (Wilcoxon signed test and Kendall’s tau correlation coefficient) and intraobserver repeatability (intraclass correlation coefficient) decreased as the voxel size increased for linear and volumetric measurements of tooth and pulp (p > 0.05). While the values indicated “good” and “excellent” reliability for all parameters measured on the 0.1- and 0.2-mm voxels, a few “moderate” reliability values were found on the 0.4-mm voxel. Conclusion Voxel sizes of 0.1- and 0.2-mm did not significantly affect linear and volumetric tooth measurements. When the voxel size increased, the reliability and repeatability decreased. To increase measurement reliability, the voxel size should be as small as possible.

Abstract Objectives To translate and revise the Contraceptive Knowledge Assessment (CKA) scale and apply it to Chinese college male/female students. After cross-cultural adjustment of the source scale, the reliability and validity of the Chinese version of the scale were tested. Study design This study utilized a cross-sectional research design. Translation, cognitive interviews and a psychometric evaluation were carried out. A survey was then conducted among 388 college students in Shanghai to test the reliability and validity of the Chinese version of the CKA scale. Results There were 22 items in the Chinese version. Factor analysis extracted 8 common factors, with a cumulative contribution rate of 58.923%, and 3 items were eliminated. The Cronbach’s α coefficient was 0.793, and the test-retest reliability Pearson correlation coefficient was 0.743. Conclusion The Chinese version of the CKA scale has good reliability and validity and is suitable for assessing the level of contraceptive knowledge.

Abstract Background Validated and internationally standardised measurement instruments are a prerequisite for ensuring that physical activity during pregnancy is comparable and for deriving physical activity recommendations. In Germany, there has been no adapted version of the internationally used Pregnancy Physical Activity Questionnaire (PPAQ) until now. This study’s aim centred around translating the original English version into German (PPAQ-G) and determining its reliability as well as validity in a German population. Methods The PPAQ was translated into German using the forward-backwards technique. Its reliability and validity were tested. Thirty-four correctly completed questionnaires were analysed. The test–retest reliability was presented using the intraclass correlation coefficient (ICC) and Spearman correlation coefficient. Validity was tested by using accelerometer (n = 23) and determined by Spearman correlation coefficient. Results In the transcultural adjustment, two questions were amended to describe intensity more precisely, and two other questions were adapted to reflect the units of measurement used in Germany. The ICC indicated a reliability of r = 0.79 for total activity (without sitting), and the intensity subcategories ranged from r = 0.70 (moderate-intensity activities) to r = 0.90 (sitting). Although, validity assessment showed no significant correlation for sedentary, moderate or vigorous intensity, there were significant correlations for total activity (light and above; r = 0.49; p

Abstract Fibromyalgia (FM) is chronic, widespread musculoskeletal pain and accompanying fatigue, sleep disturbances, cognitive, psychological, and somatic symptoms. The aim of the study is to assess the psychometric properties of the Polish version of the 36-item WHODAS 2.0 in FM patients. This is a cross-sectional study involving 456 FM polish patients. The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) 36-item version, the Fibromyalgia Impact Questionnaire (FIQ) and Beck’s Depression Inventory (BDI) were used as an assessment tool in the study. The internal consistency of the 36-item WHODAS 2.0 was assessed using Cronbach’s alpha. Values ranging from 0.824 to 0.951 were obtained. The interclass correlation coefficients (ICC) were very high. Internal structure of the 36-item WHODAS 2.0 was checked with Confirmatory Factor Analysis (CFA). RMSEA = 0.069, CFI = 0.963, TLI = 0.96, SRMR = 0.081 proved exactness of original six-dimensional structure of WHODAS 2.0. External validity was assessed by correlating the 36-item WHODAS 2.0 scores with the scores of two previously validated tools: FIQ and BDI. Positive correlations were obtained between the 36-item WHODAS 2.0 and these tools. Based on the conducted research, it has been shown that the 36-item WHODAS 2.0 is a reliable and valid tool for assessing disability in individuals with FM in Poland.

Backgrounds/Aims To systematically evaluate inter-reader agreement in the assessment of individual liver imaging reporting and data system (LI-RADS) category M (LR-M) imaging features in computed tomography/magnetic resonance imaging (CT/MRI) LIRADS v2018, and to explore the causes of poor agreement in LR-M assignment. Methods Original studies reporting inter-reader agreement for LR-M features on multiphasic CT or MRI were identified using the MEDLINE, EMBASE, and Cochrane databases. The pooled kappa coefficient (κ) was calculated using the DerSimonian-Laird random-effects model. Heterogeneity was assessed using Cochran’s Q test and I2 statistics. Subgroup meta-regression analyses were conducted to explore the study heterogeneity. Results In total, 24 eligible studies with 5,163 hepatic observations were included. The pooled κ values were 0.72 (95% confidence interval [CI], 0.65-0.78) for rim arterial phase hyperenhancement, 0.52 (95% CI, 0.39-0.65) for peripheral washout, 0.60 (95% CI, 0.50-0.70) for delayed central enhancement, 0.68 (95% CI, 0.57-0.78) for targetoid restriction, 0.74 (95% CI, 0.65-0.83) for targetoid transitional phase/hepatobiliary phase appearance, 0.64 (95% CI, 0.49-0.78) for infiltrative appearance, 0.49 (95% CI, 0.30-0.68) for marked diffusion restriction, and 0.61 (95% CI, 0.48-0.73) for necrosis or severe ischemia. Substantial study heterogeneity was observed for all LR-M features (Cochran’s Q test, P

Abstract Purpose To assess the test–retest and inter-rater reliability of goniometry and fleximetry in measuring cervical range of motion in individuals with chronic neck pain. Methods A reliability study. Thirty individuals with chronic neck pain were selected. Cervical range of motion was measured by goniometry and fleximetry at two time points 7 days apart. To characterize the sample, we used the numerical pain rating scale, Pain-Related Catastrophizing Thoughts Scale, and Neck Disability Index. Intraclass correlation coefficient (ICC), standard error of measurement (SEM) and minimum detectable change (MDC) were calculated. Correlations between goniometry and fleximetry measurements were performed using Spearman’s correlation coefficient (rho). Results For goniometry, we found excellent test–retest reliability (ICC ≥ 0.986, SEM ≤ 1.89%, MDC ≤ 5.23%) and inter-rater reliability (ICC ≥ 0.947, SEM ≤ 3.91%, MDC ≤ 10.84%). Similarly, we found excellent test–retest reliability (ICC ≥ 0.969, SEM ≤ 2.71%, MDC ≤ 7.52%) and inter-rater reliability (ICC ≥ 0.981, SEM ≤ 1.88%, MDC ≤ 5.20%) for fleximetry. Finally, we observed a strong correlation between the goniometry and the fleximetry for all cervical movements (rho ≥ 0.993). Conclusion Goniometry and fleximetry measurements are reliable for assessing cervical range of motion in individuals with chronic neck pain.

Abstract Background Radiomics is not yet used in clinical practice due to concerns regarding its susceptibility to technical factors. We aimed to assess the stability and interscan and interreader reproducibility of myocardial radiomic features between energy-integrating detector computed tomography (EID-CT) and photon-counting detector CT (PCD-CT) in patients undergoing coronary CT angiography (CCTA) on both systems. Methods Consecutive patients undergoing clinically indicated CCTA on an EID-CT were prospectively enrolled for a PCD-CT CCTA within 30 days. Virtual monoenergetic images (VMI) at various keV levels and polychromatic images (T3D) were generated for PCD-CT, with image reconstruction parameters standardized between scans. Two readers performed myocardial segmentation and 110 radiomic features were compared intraindividually between EID-CT and PDC-CT series. The agreement of parameters was assessed using the intraclass correlation coefficient and paired t-test for the stability of the parameters. Results Eighteen patients (15 males) aged 67.6 ± 9.7 years (mean ± standard deviation) were included. Besides polychromatic PCD-CT reconstructions, 60- and 70-keV VMIs showed the highest feature stability compared to EID-CT (96%, 90%, and 92%, respectively). The interscan reproducibility of features was moderate even in the most favorable comparisons (median ICC 0.50 [interquartile range 0.20–0.60] for T3D; 0.56 [0.33–0.74] for 60 keV; 0.50 [0.36–0.62] for 70 keV). Interreader reproducibility was excellent for the PCD-CT series and good for EID-CT segmentations. Conclusion Most myocardial radiomic features remain stable between EID-CT and PCD-CT. While features demonstrated moderate reproducibility between scanners, technological advances associated with PCD-CT may lead to greater reproducibility, potentially expediting future standardization efforts. Relevance statement While the use of PCD-CT may facilitate reduced interreader variability in radiomics analysis, the observed interscanner variations in comparison to EID-CT should be taken into account in future research, with efforts being made to minimize their impact in future radiomics studies. Key Points Most myocardial radiomic features resulted in being stable between EID-CT and PCD-CT on certain VMIs. The reproducibility of parameters between detector technologies was limited. PCD-CT improved interreader reproducibility of myocardial radiomic features. Graphical Abstract

Spinal alignment can be assessed without radiation using three-dimensional ultrasound imaging (3DUS). Reliable measurements could inform the ideal arm position for scoliosis radiographs. This study determined the inter-evaluator reliability of axial vertebral rotation (AVR) measurements and sagittal curve angles in healthy females from 3DUS spinal images in standing with two common radiograph arm positions: Chin and abduction (Abd). Three novice evaluators (R1, R2, and R3) measured images once. The Bland–Altman bias and limits of agreement (LOA) were calculated. T5-T12 kyphosis measurements met our bias and LOA error threshold only for R1 vs R2 in the Chin position [−0.53° (−10.7,9.7)]. The distance between the bias and the LOA also met our acceptable threshold of 5° for all mean AVRTwist, and all but one AVRTwist measurements (R1-R2_Chin = 5.9°). Three lordosis measurements did not meet our acceptable threshold (R1-R2_Chin, R1-R3_Chin, and R2-R3_Abd). The inter-evaluator reliability of novice evaluators was adequate and did not differ significantly between positions. [ABSTRACT FROM AUTHOR]

Background: Dynamic Computed Tomography Angiography (4D CTA) has the potential of providing insight into the biomechanical properties of the vessel wall, by capturing motion of the vessel wall. For vascular pathologies, like intracranial aneurysms, this could potentially refine diagnosis, prognosis, and treatment decision‐making. Purpose: The objective of this research is to determine the feasibility of a 4D CTA scanner for accurately measuring harmonic diameter changes in an in‐vitro simulated vessel. Methods: A silicon tube was exposed to a simulated heartbeat. Simulated heart rates between 40 and 100 beats‐per‐minute (bpm) were tested and the flow amplitude was varied, resulting in various changes of tube diameter. A 320‐detector row CT system with ECG‐gating captured three consecutive cycles of expansion. Image registration was used to calculate the diameter change. A vascular echography set‐up was used as a reference, using a 9 MHz linear array transducer. The reproducibility of 4D CTA was represented by the Pearson correlation (r) between the three consecutive diameter change patterns, captured by 4D CTA. The peak value similarity (pvs) was calculated between the 4D CTA and US measurements for increasing frequencies and was chosen as a measure of temporal resolution. Spatial resolution was represented by the Sum of the Relative Percentual Difference (SRPD) between 4D CTA and US diameter change patterns for increasing amplitudes. Results: The reproducibility of 4D CTA measurements was good (r ≥ 0.9) if the diameter change was larger than 0.3 mm, moderate (0.7 ≤ r < 0.9) if the diameter change was between 0.1 and 0.3 mm, and low (r < 0.7) if the diameter change was smaller than 0.1 mm. Regarding the temporal resolution, the amplitude of 4D CTA was similar to the US measurements (pvs ≥ 90%) for the frequencies of 40 and 50 bpm. Frequencies between 60 and 80 bpm result in a moderate similarity (70% ≤ pvs < 90%). A low similarity (pvs < 70%) is observed for 90 and 100 bpm. Regarding the spatial resolution, diameter changes above 0.30 mm result in SRPDs consistently below 50%. Conclusion: In a phantom setting, 4D CTA can be used to reliably capture reproducible tube diameter changes exceeding 0.30 mm. Low pulsation frequencies (40 or 50 bpm) provide an accurate measurement of the maximum tube diameter change. [ABSTRACT FROM AUTHOR]

Purpose: To assess the repeatability, intra and interrater reproducibility of the DIPA-S eHealth© system for capturing and measuring clinical variables of scoliosis, including frontal trunk imbalance (FTI), sagittal trunk imbalance (STI), and angle of trunk rotation (ATR). Methods: Patients were photographed using the DIPA-S eHealth Capture© mobile application by family members, physiotherapists, or surgeons. Three photos were taken in each position: standing in the frontal and sagittal planes and in the axial plane in forward bending position of the trunk. The photos were analyzed by three independent evaluators using the DIPA-S eHealth Analysis© software. For repeatability, each photo was analyzed twice consecutively by the three evaluators. For intrarater reproducibility, only one evaluator reanalyzed the first photo from each plane with a 5-day interval. For interrater reproducibility, the three evaluators analyzed the first photo from each plane. The intraclass correlation coefficient (ICC), standard error of measurement (SEM), and minimal detectable change (MDC) were used (p < 0.05). Results: The sample comprised 262 images (n = 30). Repeatability was excellent for all three evaluators in all three planes (ICC 0.94 to 1.00). Intrarater reproducibility was excellent in all three planes (ICC 0.88 to 0.99). Interrater analysis was excellent for the frontal and axial planes (ICC 0.98 and 0.93), respectively. However, it was weak in the sagittal plane ICC 0.32. The SEM ranged from 0.02 to 17.6 and MDC from 0.03 to 34.6. Conclusion: The DIPA-S eHealth© Capture and Analysis system demonstrates reproducibility for use in the clinical assessment of scoliosis through teleconsultations. [ABSTRACT FROM AUTHOR]

Background: Prior research has shown that using lifetime abstainers as the reference group to examine the association between alcohol use and health‐related consequences has several disadvantages. The aim of the present study was to examine the consistency of self‐reported lifetime abstention and never‐binge drinking, respectively, using national, longitudinal data collected in 2019 and 2020. Additionally, the prevalence of alcohol‐related morbidity among lifetime abstainers was examined by linking survey data to alcohol‐related morbidity data in a national patient register. Methods: Data come from the Danish Health and Wellbeing Survey in 2019 and from a follow‐up survey of the same individuals in 2020. A random sample of 14,000 individuals aged 15 years or older was drawn in mid‐August 2019. Data were collected between September and December 2019. All those who were invited to the survey in 2019 and who were still alive and living in Denmark were invited to participate in a follow‐up survey in 2020. Data in both waves were collected by self‐administered questionnaires. Both questionnaires included the standard questions on alcohol consumption from the European Health Interview Survey model questionnaire. Information on alcohol‐related morbidity was obtained from the Danish National Patient Register. Results: In all, 5000 individuals completed the questionnaire in both waves. Approximately half (44.4%) of the individuals who declared that they were lifetime abstainers in 2020 (n = 252) had reported in 2019 to have drunk at some point in their life. Moreover, 39.7% contradicted earlier reported binge drinking. Furthermore, 2.4% of the respondents who defined themselves as lifetime abstainers in 2020 had earlier been diagnosed with an alcohol‐related health condition. Conclusion: The present research reaffirms previous studies which have found self‐reported lifetime abstainers to be unreliable as a consistent reference group. Additionally, the results indicated that a non‐negligible proportion of lifetime abstainers had been diagnosed with an alcohol‐related health condition. [ABSTRACT FROM AUTHOR]

Objective: The purpose of this study was to establish the interrater reliability of measures obtained with a novel Modified Prone Instability Test (mPIT), which, like the original Prone Instability Test (PIT), is proposed to identify lumbar segmental instability. The mPIT has clinical feasibility advantages to the PIT, but its psychometric properties are yet to be determined. Design: Repeated measures (test-retest) design, methods study Methods: The mPIT was administered by two blinded testers, an orthopedic physical therapy resident with < 1 year experience and board-certified orthopedic specialist physical therapist with >25 years' experience. Procedures were administered at an outpatient physical therapy clinic of a tertiary Medical Center. Participants included 50 adults (≥18 years old) with mechanical low back pain and no radicular (below the knee) symptoms (mean age 50.7 years, 66% female, 76% reported previous episodes of low back pain). Interrater reliability was measured via Fleiss' kappa coefficient. Results: Assessments of the mPIT had moderate interrater agreement (κ =.579 [95% CI =.302 to.856], p <.001.) Conclusion: Measures obtained using the mPIT demonstrated moderate interrater reliability between a new graduate and an experienced clinician, which aligns with several studies examining interrater reliability of the original PIT. Further study examining comparative validation of the mPIT with other lumbar instability measures is warranted. [ABSTRACT FROM AUTHOR]

Actinic keratosis (AK) is a common precancerous skin condition predominantly affecting older males with fair skin and significant UV exposure. The clinical significance of AK is related to its potential for malignant transformation and progression to squamous cell carcinoma (SCC). Accurate diagnosis of AK is essential for adequate treatment, evaluation of therapeutic efficacy, and mitigating the risk of developing SCC. However, clinician variability due to the subjective nature of current diagnostic tools presents significant challenges to achieving consistent and reliable AK diagnoses. Thus, there is no universally accepted standard for measuring AK. This review evaluates current methods for evaluating and diagnosing AK, focusing on clinician variability through inter- and intraobserver agreement. Eight peer-reviewed studies investigating the reliability of various approaches for AK evaluation show substantial variability in interobserver or intraobserver agreement, with most methods demonstrating only slight to moderate reliability. Some suggest that consensus discussions and simplified rating scales can modestly improve diagnostic reliability. However, remaining variability and the lack of a universally accepted standard for measuring AK underscore the need for more robust and standardized diagnostic and evaluation methods. The review emphasizes the need for improved diagnostic tools and standardized methods to enhance the accuracy and reliability of AK assessments. It also proposes applying a novel examination approach using 1,3-dihydroxyacetone (DHA) staining which may improve the visualization and identification of AK lesions. Advancements in these areas have significant potential, promising better clinical practices and patient outcomes in AK management. [ABSTRACT FROM AUTHOR]

The Modified Sphygmomanometer Test (MST) is a method for assessing muscle strength that offers objective measures similar to those of a portable dynamometer, while also being cost-effective. However, previous studies have not investigated the measurement properties of the MST in adolescents. Thus, the objectives of the study were (1) to examine the concurrent criterion validity, test-retest and interrater reliability of the Modified Sphygmomanometer Test (TMS) for assessing muscle strength in adolescents, (2) to calculate the Standard Error of Measurement (EPM) and the smallest real difference (SRD) of muscle strength values; and (3) analyze the different forms of operationalization and their influence on the results obtained. Fifty-two adolescents (mean age: 16.5 ± 0.70 years) participated in the study. Muscle strength of the upper limbs (UL) and trunk was assessed using the MST and portable dynamometers. The Spearman test was used to determine concurrent criterion validity and the intraclass correlation coefficient (ICC) was used to assess reliability (α = 0.05). To analyze the stability of the measurements (SEM and SRD), the 95% test-retest confidence interval (CI) and inter-rater reliability were considered for all data collected. ANOVA was performed to explore different methods of operationalizing the MST. Criterion validity, test-retest reliability and moderate to very high inter-rater reliability (0.61≤r ≤ 0.94; p < 0.001; 0.63≤ICC≤0.97; p < 0.001) were found for the groups assessed muscles and different forms of operationalization, with no statistically significant differences between the different operationalization approaches. Therefore, the MST demonstrated adequate measurement properties for assessing muscle strength in adolescents. [ABSTRACT FROM AUTHOR]

The Constant-Murley Score (CMS) uses universal goniometry (UG), and the Shoulder Functional Reach Score (SFRS) uses visual estimation (VE). The CMS has validity challenges, and the SFRS has been critiqued for using VE. This study sought to determine the reliability and concurrent validity of VE when compared to the UG for shoulder flexion and abduction. Differences between symptomatic and asymptomatic shoulder and expert and novice raters were also explored. Participants were included if they were at least 18 years old with unilateral, symptomatic shoulder pain, with no post-surgical contraindications. All conditions were randomized, and raters were blinded. The intertester reliability for UG had Intraclass Correlation Coefficient (ICC) values of 0.76–0.91 at visit one. VE had ICC values that ranged from 0.87 to 0.92 at visit one. VE test-retest reliability had ICC values from 0.81 to 0.94. At visit one, concurrent validity was demonstrated by rho values from 0.84 to 0.89. There were statistically significant differences between the shoulders (P ≤ 0.0448), and there were no differences between the raters (P ≥ 0.0960). UG and VE of active shoulder flexion and abduction are reliable and concurrently valid. Additionally, there were differences between symptomatic and asymptomatic shoulders, and there were no differences between novice and expert raters. The SFRS may be reliable and valid for measuring shoulder motion using VE within and between treatment sessions. Future research should examine this in larger, more diverse participant populations.

Although the importance of trunk position sense as a clinical outcome measure related to spinal alignment has been established, there is no study evaluating the reliability of measurement techniques for trunk position sense in older adults. Hyperkyphosis is most prevalent in this population and is associated with adverse consequences. This study aimed to investigate the test-retest reliability of a measurement technique consisting of photogrammetry and angle calculation in older adults with and without hyperkyphosis. Fifty-three older adults completed the tests. Participants actively reproduced a trunk neutral position (TNP) from both a trunk extended position and a trunk flexed position. Absolute error (AE) and variable error (VE) indices were calculated to quantify position sense acuity. Intraclass Correlation Coefficient was used to estimate relative reliability. Absolute reliability was assessed by calculating Standard Error of the Measurements (SEM) and Minimal Detectable Change (MDC). The digital photogrammetry showed excellent reliability for horizontal and global components of AE in both hyperkyphosis and control groups while reproducing the TNP from trunk flexion. Also, there was good reliability for AE and VE in the hyperkyphosis group when moving to the TNP from the trunk extension. The MDC values for AE ranged from 0.32 to 0.44 while reproducing the TNP from trunk flexion. The MDC values for AE ranged up to 0.96 when reproducing the TNP from trunk extension. This study suggests that digital photogrammetry is a reliable method with clinical applicability, which allows the detection of changes after clinical interventions. [ABSTRACT FROM AUTHOR]

Background: Quantitative diffusion metrics provide additional microstructural information of diseases. The robustness of quantitative diffusion metrics should be established before clinical application. Purpose: To evaluate the variability and reproducibility of quantitative diffusion MRI metrics. Study Type: Prospective. Population: 14 volunteers (7 men; median age, range, 28, 26–59 years). Field strength/Sequence: 3.0‐T/Diffusion spectrum imaging. Assessment: Brain MRI studies were performed four times per subject: involving different combinations of coil types and voxel sizes. Regions of interest of 13 brain anatomical sites were drawn by one observer twice and another observer once to allow interobserver and intraobserver reproducibility assessment. Twenty‐five quantitative metrics were calculated using four diffusion models. Statistical Tests: The variability was evaluated with coefficients of variation (CV), and quartile coefficient of dispersion (QCD). The reproducibility was assessed with intraclass correlation coefficient (ICC), and concordance correlation coefficient (CCC). Wilcoxon signed rank test was used to compare the influence of factors on robustness of quantitative diffusion metrics. A two‐tailed P < 0.05 was considered statistically significant. Results: The variability of quantitative diffusion metrics showed CV of 2.4%–68.2%, and QCD of 0.6%–48.2%, respectively. The reproducibility of scans using 20‐channel coils with voxels of 2 × 2 × 2 mm3 and 3 × 3 × 3 mm3, respectively (ICC 0.03–0.84, CCC 0.03–0.84) was significantly worse than that of repeated scans using a 20‐channel coil with a voxel size of 2 × 2 × 2 mm3 (ICC of 0.74–0.97, CCC 0.74–0.97) and that of scans using 20‐ and 64‐channel coils, respectively, with a voxel size of 2 × 2 × 2 mm3 (ICC 0.59–0.95, CCC 0.59–0.95). The intraobserver reproducibility (ICC 0.49–0.94, CCC 0.49–0.94) was significantly better than the interobserver reproducibility (ICC 0.28–0.91, CCC 0.28–0.91). Data Conclusion: Our study indicated that the voxel size has a greater influence on the reproducibility of quantitative diffusion metrics than scan‐rescans and coils. The reproducibility within one observer was higher than that between two observers. Evidence Level: 2 Technical Efficacy: Stage 1 [ABSTRACT FROM AUTHOR]
