This study was designed to investigate the reliability and validity of measurements of finger diameters with a ring gauge. A reliability study enrolled two independent samples (50 participants and seven examiners in Study I; 26 participants and 26 examiners in Study II). The sizes of each participant’s little fingers were measured twice with a ring gauge by each examiner. To investigate the validity of the measurements, five hand therapists compared the finger size and hand volume of 30 participants with the ring gauge and with a figure-of-eight technique (Study III). The intra-class correlation coefficient for intra-observer reliability ranged from 0.97 to 0.99 in Study I, and 0.90 to 0.97 in Study II. The intra-class correlation coefficient for inter-observer reliability was 0.95 in Study I and 0.94 in Study II. The validity study showed a Pearson product moment correlation coefficient of 0.75. The ring gauge showed high reliability and validity for measurement of finger size. Level of evidence: III, diagnostic

Katz and Stirrat devised a hand diagram, which uses subjective information from the patient for the diagnosis of carpal tunnel syndrome (CTS). They reported a good result. We tested the inter-observer and intra-observer reliability of this hand diagram. Twenty five consecutive patients with a diagnosis of CTS, 25 with other common hand and wrist problems but CTS and 25 healthy individuals were prospectively recruited. Each patient filled in a hand diagram. Two experienced hand surgeon scored the diagrams blindly on two different sittings four-week apart. The intra-class correlation coefficient (ICC) and Cohen's Kappa were used for intra and inter-observer reliability respectively. The intra-observer agreement was poor (ICC 95% 0.33–0.65) and inter-observer was fair (Kappa = 0.241). This study does not support the use of Katz and Stirrat Hand Diagram for the diagnosis of carpal tunnel syndrome in place if a thorough clinical examination.

Ankle swelling is a commonly encountered condition in physiotherapy practice. Reliable and easy methods of quantification are required to record progress in treatment. The aim of this study was to establish the inter- and intra-reliability of the figure-of-eight tape measure for measuring ankle size. Thirty-six healthy subjects were measured in long-sitting position with the foot hanging free over the edge of a plinth. Three testers performed four measurements each for a total of 12 measurements per subject. The intra-class correlation coefficient was 0.96 for inter-tester reliability and 0.94 for intra-tester reliability. The results agree with previous reliability studies using the figure-of-eight tape method on healthy subjects. The figure-of-eight tape method is easily learned and applied. It is a reliable method for measuring ankle size. Further research is needed to demonstrate the reliability and validity of the technique in a clinical setting.

Maximal aerobic capacity (VO2 max) is one of the important factors that influence swimming performance. Currently, the Garmin Forerunner Fitness Watch 935 used to measure VO2 max are expensive, require skilled-trained personnel, not feasible for large-scale use, and land-based, which will not be accurate in measuring water-based activity. In order to measure the swimming performance, there is a need for an affordable, feasible, and reliable device. Therefore, the current study aimed to examine the intra-rater reliability of Garmin Forerunner Fitness Watch 935 accuracy in measuring the VO2 max among collegiate swimmers during the 200m swimming task. The VO2 max measurement of 10 collegiate swimmers was taken with Garmin Forerunner for two trials. The intra-class correlation coefficient (ICC), standard error of measurements (SEMs), and Bland-Altman plot was used in the current study to establish the inter-rater reliability measurement. The intra-rater reliability of Garmin Forerunner showed high reliability and accuracy with an intra-class correlation coefficient (2,1) of 0.869 and standard error of measurements of 0.231 ml/kg/min. Further, the results were strengthened with Bland-Altman plot showed an acceptable agreement between the two trials. The Garmin Forerunner would be a simple, objective and useful device to be used by physiotherapists, trainers and other sports-related disciplines to assess and improve the swimming performance by targeting the heart rate and VO2 max.

This study evaluates the reliability and validity of the Perceptual Therapy Systems (PTS) tachistoscope test. 74 poor readers in grade school were tested twice with the tachistoscope test. This test purports to measure visual skils important in reading. Poor readers should perform poorly on it. Results: The PTS tachistoscope has good-to-excellent reliability per the intra-class correlation coefficient (ICC) and fair-to-good reliability per Cohen’s Kappa index. The poor readers performed, on average, at the scaled score level of 7. Conclusions: The PTS tachistoscope test has sufficient reliability. Its validity is supported by the fact that poor readers, determined as such by case history, performed poorly on it.

Improvement in rider mobility represents an important functional gain for people with disabilities undergoing hippotherapy. However, there is no validated measuring instrument to track and document the rider's progress in riding activities. In this study, we aimed to develop and establish validity evidence for an instrument to assess hippotherapy participants’ mobility on horseback. We report on this development through the stages of: (a) content validation, (b) construct validation, (c) inter- and intra-rater reliability and (d) internal consistency analysis. We evaluated its factor structure with exploratory factor analyses, calculated values for inter- and intra-rater reliability using the intra-class correlation coefficient, and calculated its internal consistency using Cronbach's alpha. We followed recommendations by the Guidelines for Reporting Reliability and Agreement Studies. We found good inter-rater reliability (intra-class correlation coefficient – ICC = 0.991–0.999) and good intra-rater reliability (ICC = 0.997–1.0), and there was excellent internal consistency (Cronbach's α = 0.937–0.999). The instrument’s factor structure grouped its three domains into one factor. As this instrument is theoretically consistent and has been found to be appropriate and reliable for its intended use, it is now available for the measurement of horseback mobility among hippotherapy riders.

Background and Objectives: The techniques directed to the cranial field in osteopathy are the most questioned due to the lack of scientific evidence. In osteopathic practice, manual palpation is essential and, therefore, measuring reliability is fundamental. The objective of this study is to assess the precision and objectification of an educational model in cranial osteopathy based on experience. Materials and Methods: A reliability study was conducted in a cadaver skull where a strain gauge was placed on the sphenobasilar synchondrosis (SBS) of the base of the skull. Three cranial osteopathic techniques (lateral compression, anteroposterior compression, and compression maneuver of the mastoids) were performed 25 times by osteopaths with different degrees of experience (5–10 years, 1–5 years, <1 year). Measurements were computed for each of the three techniques of each group in comparison with the osteopath with >15 years of experience. Data were analyzed to check for inter- and intra-observer reliability using intra-class correlation coefficients (ICC). Results: Reliability in osteopaths with 5–10 years’ experience (observer 1 and observer 2) performing all three techniques was higher (p < 0.001) than the osteopath with >15 years’ experience. Little or no reliability were observed in osteopaths with less experience. Conclusions: The experience of the osteopaths determines the reliability and effectiveness of the cranial techniques, a fundamental part in objectifying these techniques. This model can help implement objective training in cranial osteopathy formation.

Introduction: The objective of this study was to adapt the Brazilian version, and verify the validity, reliability and internal consistency of the Oliveira questionnaire on low back pain in young people.Material and Methods: The questionnaire was translated from European Portuguese into Brazilian Portuguese by means of translation and re-translation. The validity of the contents was determined by experts who analyzed the clarity and pertinence of the questions. Fifteen young people aged 15 to 18 took part in the pre-test step (qualitative analysis), 40 in the test-retest (reliability) and 679 in the evaluation of internal consistency. The intra-class correlation coefficient and Spearman’s correlation coefficient were used in the reliability analysis (test-retest), and Cronbach’s alpha to determine the internal consistency (stability).Results: In the translation phase the questionnaire was modified and considered suitable, observing similarity and equivalence of the two versions. After being corrected by the experts in the validation of the contents, the instrument was considered suitable and valid, and in the pre-test, the young people suggested some modifications to make the questionnaire more succinct. With respect to reliability, the values for the intra-class correlation coefficient were between 0.512 – acceptable and 1 – excellent and Spearman’s correlation coefficient varied between 0.525 and 1, classifying the instrument as reproducible. The internal consistency was considered acceptable with a 0.757 Cronbach’s alpha.Discussion: The Oliveira questionnaire was choosen since it has been used in several Portuguese studies; moreover, it addresses the need to raise data regarding low back pain and associated risk factors.Conclusions: The Brazilian version of the Oliveira questionnaire on low back pain in young people showed valid and reliable cultural adaptation, with good reliability and stability.

ABSTRACTBackground:Older adults represent the segment of population most exposed to the risk of suicide nearly everywhere in the world. Previous studies showed that hopelessness was an important risk factor for suicide.Aims:This study aimed to evaluate the reliability and validity of the four-item Beck Hopelessness Scale (BHS-4) in psychological autopsy study among Chinese rural elderly.Method:Two-stage stratified cluster sampling method was used to select research sites. Using case-control psychological autopsy study, face-to-face interviews were conducted to collected information.Results:A total of 242 elderly suicide deaths and 242 matched living comparisons were investigated, including 135 males and 107 females for each group. Intraclass Correlation Coefficients (ICC) of the controls were 0.682-0.713. The median score of BHS-4 among suicides was significantly higher than that among controls. The corrected correlation coefficient between items and total score were 0.184-0.723. Cronbach’s Alphas coefficient was 0.834. Only one common factor was precipitated by exploratory factor analysis and the cumulative variance contribution rates were 59.558% for suicides and 52.722% for living controls. The correlation coefficient between hopelessness and depression were 0.481 among suicide death and 0.617 among living controls.Conclusion:The information provided by the informants through psychological autopsy method had high reliability to reflect the actual situation of suicides and controls. BHS-4 has good reliability and validity among Chinese rural elderly suicides. It is suitable for psychological autopsy study among Chinese rural elderly.
