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.

Background: There are several methods for measuring edema of the hand. While the volumetric techniques, finger circumference measurement, and figure-of-eight techniques have undergone extensive psychometric testing, alternative methods of measuring hand size, such as circumferential finger size determination using a ring gauge (ring gauge method; RGM) and tape measurement of hand girth taken along the distal palmar crease (metacarpal head tape measure method; MHTM), have not. This study's aim is to examine the reliability and validity of the RGM and the MHTM. Methods: In this cross-sectional study, two examiners measured 22 hands in 22 patients with hand edema using the RGM and the MHTM 3 times each to determine intra- and inter-tester reliability. The validity of each method was established using the finger circumference measurement and figure-of-eight method, respectively. Results: The intra-class correlation coefficient (ICC) obtained for intra-tester reliability was 0.99–0.98 for both methods. ICCs for inter-tester reliability were 0.97–0.98 for the RGM and 0.98 for the MHTM. Pearson product-moment correlation values between the RGM and finger circumference measurement were 0.92–0.96, while those between the MHTM and figure-of-eight method were 0.84–0.90. Conclusions: The RGM and the MHTM are reliable and valid evaluation tools for the assessment of hand size.

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

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.

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.

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.

Abstract Background:Cross-table lateral (CL) radiography is aconvenientandfeasible method toassess cup version angle (VA) after total hip arthroplasty; however, the pelvic tilt (PT) may contribute to its measurement inaccuracy.We sought (1) to determinethe effect of the PT on cup version measurement on CL radiography and (2) to develop a method for reducing measurement errors caused by the PT.Methods: Two groups of VAswere measured respectively on 3D simulatedCL images and CL radiographs. Based on the data, we created a corrective formula to convert the radiographic measurements into values approximating the actual VA under a natural pelvic position. The corrected valueswere compared with computed tomography (CT) measurements to verified the corrective formula. Results:There was a high correlation between the measurements and PTs. For each 1-degree increased in the PT, the VA decreased by 0.76° (R²=0.995, p<0.001). The VA measurements corrected by our equation was in high agreement with the CT-measured valueswithreferenceto the corresponding PT (intra-class correlation coefficient [ICC]=0.988, p<0.001), which was in sharp contrast to that without PT control (ICC=0.454, p=0.203).Conclusions: ThePT may contribute to cup version measurement inaccuracies on CL radiography. Our mathematical algorithm can serve as a reliable method to improve the accuracy of CL radiography.
