ABSTRACT Objectives: To evaluate the precision of the virtual occlusal record using the Carestream CS3600 Intraoral Scanner (Carestream Dental, Atlanta, Ga). Materials and Methods: A total of 20 participants were recruited for this prospective study using preestablished inclusion/exclusion criteria. A complete intraoral scan and two bite registrations were obtained. The participants were instructed to bite with normal pressure when bite registrations were acquired. Contact locations, size (circumference), and intensity were identified on the maxillary first molars and canines. Agreement between contact size and intensity was assessed with intraclass correlation coefficients. Kappa statistics evaluated agreement in contact locations. Statistical significance was set at P < .05. Results: All participant data were included for statistical analysis. Between the two bite registrations, nonstatistically significant differences were observed in the proportion of locations with contacts (P = .7681). A nonstatistically significant difference (−0.25 mm, P = .8416) in mean contact circumference size was observed. A statistically significant difference in mean contact intensity was observed (P = .0448). When evaluating agreement between the bite registrations, a weak correlation for size (intraclass correlation coefficient = 0.35) and intensity (intraclass correlation coefficient = 0.32) was observed as well as a moderate agreement for contact location (κ coefficient = 0.67). Conclusions: The findings suggest that the Carestream intraoral scanner software possesses adequate precision when acquiring the location and size of the contacts in bite registrations. The scanner failed to demonstrate adequate precision when acquiring contact intensities in bite registrations. Additional research is warranted to further investigate the precision of virtual occlusal records with currently available software systems.

Objective To quantify the degree of change in cervical length (CL) over a 3-minute transvaginal ultrasound. Study Design We conducted a prospective observational study of nulliparous patients who underwent routine transvaginal CL screening at the time of their second-trimester ultrasound. We recorded CL at four time points (0, 1, 2, 3 minutes) and compared these values to determine the minute-to-minute change within a single patient. Results A total of 771 patients were included. The mean gestational age was 20.8 weeks (±0.84). We used a linear mixed effect model to assess if each minute during the ultrasound is associated with a change in CL. The intraclass correlation coefficient between minute 0 to minute 3 was 0.82 (95% confidence interval: 0.80, 0.84). This indicates that there is a relatively high within-patient correlation in CL during their ultrasound. Additionally, we stratified patients based on their starting CL; the intraclass correlation coefficient remained high for all groups. We additionally compared CL at each minute. Although there is a statistically significant difference between several time points, the actual difference is small and not clinically meaningful. Conclusion The variation in CL over a 3-minute transvaginal ultrasound examination is not clinically significant. It may be reasonable to conduct this examination over a shorter period.

Toe Pressure

Introduction Ankle/brachial indices are inaccurate in the presence of calcification, and physicians may rely on the measurement of digital pressures. As the population continues to age and with the escalation in type 2 diabetes, the importance of, and reliance on, toe pressure measurements will increase. The aim of this study was to assess the reproducibility of toe pressure measurements in a single vascular laboratory. Methods Repeated ankle/brachial indices and toe pressures were measured in 20 patients (10 with known peripheral vascular disease and 10 with aneurysmal or carotid artery disease but no history of PVD), and 10 control patients. Three measurements were made 48 hours apart. All measurements were made by a single vascular technologist. Reproducibility was assessed by the use of the repeatability coefficient and the intraclass correlation coefficient. Results Ankle/brachial indices ranged from 0.36 to 2.4, toe pressures from 18 mmHg to 173 mmHg, and toe/brachial indices from 0.11 to 1.1. The repeatability coefficient showed no significant difference between measurements ( p > 0.1) and the intraclass correlation coefficient estimates showed high agreement between repeated measurements (0.77–0.99). Bland-Altman plots indicated that the observer variability was equally distributed across the range of pressure measurements. Conclusion These results confirm the intraobserver reproducibility of toe pressure measurements; however, further work is required to demonstrate inter-observer reproducibility.

Introduction: Accurate corneal wavefront aberration measurements are essential in determining patient’s suitability, vision outcomes and patient satisfaction in laser refractive surgeries. This study aimed to evaluate the reliability measurement of higher-order aberration (HOA) using corneal videokeratograph Atlas 9000. Materials and method:  38 eyes of 19 participants were recruited in this study. Comprehensive eye examination was done to ensure all participants eligibility, and any conditions in which obstruct the central cornea were excluded. Corneal wavefront aberrations were measured based on Zernike polynomials. In assessing repeatability, three repetitive measurements in five minutes in a single session were taken by 2 experience examiners. For reproducibility measurement, similar approach was done with the time-interval between measurements was set at one week. Bland-Altman, limits of agreement (LoA) and intraclass correlation coefficients (ICCs) were used to evaluate the reliability measurement. Results: Bland-Altman and LoA findings revealed no significant differences for both repeatability and reproducibility measurement. For repeatability testing, the mean differences for vertical trefoil, oblique trefoil and spherical aberration were -0.096 ± 0.493, 0.001 ± 0.048, 0.008 ± 0.035, 0.004 ± 0.029, 0.010 ± 0.053 with LoA of 1.930, 0.188, 0.138, 0.114, and 0.208 respectively. Intraclass correlation coefficient (ICC) excellent reliability of 0.841 for all parameters. Likewise, reproducibility  testing showed similar findings  with the mean difference were -0.018 ± 0.091, 0.016 ± 0.061, -0.0004 ± 0.036, -0.002 ± 0.042, 0.003 ± 0.026, with LoA of 0.356, 0.24, 0.141,0.164, and 0.102 respectively. Intraclass correlation coefficient (ICC) shows excellent reliability of more than 0.9 for all parameters. LoA of less than 1.0 were observed in all measurements (except for repeatability of vertical trefoil) indicates high consistency of the measurements. Conclusions: Corneal videokeratograph Atlas 9000 provides excellent HOA measurement reliability.

The Difference

Many laboratory and field tests are used in the literature to measure agility. The aim of the present study was to investigate the reliability and validity of a new Reactive Agility Test developed for badminton. A total of fourty male [ 20 elites (age: 20.8 ± 2.98 year, height: 174.55 ± 12.03 cm, weight: 65.70 ± 14.41 kg) and 20 sub-elites (age: 22.20±1,51, height: 170.01 ± 05.80 cm, weight: 62.45 ± 6,45 kg)] badminton players took part in the present study. For validity, the difference and relationship between newly developed reactive agility and planned changing direction tests in terms of elit and sub-elit players was examined. In the reliability measurements of test-retest, The Reactive Agility Test at same route was performed twice. Independent sample t test was carried out in order to detect the difference among the groups in the search for validity. The identification of the relations between the two different tests was performed with linear regression analysis. The reliability of test-retest was tried to be estimated with the coefficient of variances and intraclass correlation coefficient, and the Bland Altman method. In addition, a systematic difference between the test and the retest was estimated with the paired t test. At the end of the study, while there was not a significant difference found in the rates of planned changing direction of the elit and sub-elit players, it was detected that reactive agility rates were better in the elit players (7.14±4.85 sec and 9.87±5.07 sec, respectively). Moreover, a high coefficient determination was revealed between two tests (r2: 0.63, p<0.01). In the comparison of test-retest, a high intraclass correlation coefficient (0.930) and a very low coefficient of variances (4.7) were found. Furthermore, it was observed in the Bland Altman graph that a 95% of concordance range of the data obtained between two measurements was a good and narrow concordance.  In conclusion, it was determined that the new developed badminton specific Reactive Agility Test is a valid and reliable measurement method and it is suggested that this test protocol can be used to enhance and monitor reactive agility ability of badminton players.Extended English summary is in the end of Full Text PDF (TURKISH) file. ÖzetLiteratürde çevikliğin ölçülmesi amacıyla birçok laboratuvar ve saha testi kullanılmaktadır. Bu çalışmanın amacı badminton sporuna göre düzenlenmiş Reaktif Çeviklik Testinin güvenirlik ve geçerliğinin araştırılmasıdır. Araştırmaya toplam kırk erkek [20 elit (yaş: 20,8±2,98 yıl, boy uzunluğu: 174,55±12,03 cm, vücut ağırlığı:65,70±14,41 kg) ve 20 sub-elit (yaş: 22,20±1,51 yıl, boy uzunluğu: 170,01±05,80 cm, vücut ağırlığı:62,45±6,45 kg)] badminton oyuncusu katılmıştır. Geçerlik için yeni geliştirilen reaktif çeviklik ile planlı yön değiştirme testlerinin elit ve sub-elit katılımcılar arasındaki istatistiksel karşılaştırması ve ilişkisi analiz edilmiştir. Test-tekrar test güvenirlik ölçümlerinde aynı rotadaki reaktif çeviklik testi birer gün arayla iki kez uygulanmıştır. Geçerlik çalışmasında gruplar arası farkın belirlenmesi için bağımsız değişken t testi ve testler arası ilişkinin fonksiyonel olarak açıklanması ve bu ilişkinin bir modelle tanımlanması için basit doğrusal regresyon analizi yapılmıştır. Test-tekrar test güvenirliği varyasyon katsayısı, sınıf içi korelasyon katsayısı ve Bland Altman metodu ile kestirim edilmiştir. Ayrıca test- tekrar test arasında sistematik bir farkın olup olmadığı eşleştirilmiş t testi ile sınanmıştır.  Çalışma sonunda elit ve sub-elit oyuncuların planlı yön değiştirme bulguları anlamlı bir fark bulunmazken, reaktif çeviklik derecelerinin elit oyuncularda istatistiksel olarak anlamlı farklı (sırasıyla 7,14±4.85 sn ve 9,87±5,07 sn) şekilde düşük olduğu tespit edilmiştir. Bununla beraber her iki test arasında yüksek düzeyde  bir açıklayıcılık katsayısı tespit (r2: 0,63, p<0.01) edilmiştir. Test- tekrar test karşılaştırılmasında yüksek bir sınıf içi korelasyon katsayısı (0,930) ve çok düşük varyasyon katsayısı (4,7) belirlenmiştir. Ayrıca Bland-Altman grafiğinde iki ölçüm arasında elde edilen tüm verilerin %95 uyum aralığının dar ve iyi bir uyum gösterdiği gözlenmiştir. Sonuç olarak,  badminton sporuna göre düzenlenmiş Reaktif Çeviklik Testinin geçerli ve güvenilir bir ölçüm yöntemi olduğu tespit edilmiştir ve badminton oyuncularının reaktif çeviklik becerilerinin geliştirilmesinde ve gelişimlerinin takibinde kullanılabileceği önerilmektedir.

Foot Pronation

Several decisions need to be made when prescribing foot orthoses for abnormal foot pronation. One of these decisions is how much force is needed from orthoses to supinate the foot. The supination resistance test has been described as one technique to help determine the amount of force needed. The aim of this project was to determine the reliability of the manual supination resistance test. Four clinicians of differing levels of experience performed the test on 44 subjects (88 feet) on 2 separate days. The test had good reliability overall, with an intertester intraclass correlation coefficient of 0.89. For the two more experienced clinicians, the intratester intraclass correlation coefficients were good (0.82 and 0.78), but for the two inexperienced clinicians they were poor (0.56 and 0.62). The supination resistance test may be clinically useful in the prescription of foot orthoses, but more work is needed to determine its validity and its relationship to clinical outcomes.

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

Volumetric Measurement

Introduction: Volumetric measurements of benign tumors enable surgeons to trace volume changes during follow-up periods. For a volumetric measurement technique to be applicable, it should be easy, rapid, and inexpensive and should carry a high interobserver reliability. We aimed to assess the interobserver reliability of a volumetric measurement technique using the Cavalier’s principle of stereological methods. Materials and methods: The computerized tomography (CT) of 15 patients with a histopathologically confirmed diagnosis of enchondroma with variant tumor sizes and localizations was retrospectively reviewed for interobserver reliability evaluation of the volumetric stereological measurement with the Cavalier’s principle, V = t × [((SU) × d) /SL]2 × Σ P. Results: The volumes of the 15 tumors collected by the observers are demonstrated in Table 1. There was no statistical significance between the first and second observers ( p = 0.000 and intraclass correlation coefficient = 0.970) and between the first and third observers ( p = 0.000 and intraclass correlation coefficient = 0.981). No statistical significance was detected between the second and third observers ( p = 0.000 and intraclass correlation coefficient = 0.976). Conclusion: The Cavalier’s principle with the stereological technique using the CT scans is an easy, rapid, and inexpensive technique in volumetric evaluation of enchondromas with a trustable interobserver reliability.

We investigated the variability of strength trained athletes' self-selected rest periods between sets of heavy squat training. Sixteen strength-trained male athletes (Mage = 23, SD = 3 years) completed two squat training sessions 48 hours apart. Each training session consisted of five sets of 5RM squats, interspersed with self-selected interset rest periods. A Gymaware linear optical encoder collected kinetic data for each squat and temporal data for each interset rest period. The participants' subjective ratings of the experience were taken before (Readiness to Lift [RTL]) and after (Rating of Perceived Effort [RPE]) each set. Mean total rest time and mean power output differed significantly between sessions. For both sessions, interset rest period increased, and power output decreased between Sets 3, 4, and 5 (95% CI range [−101, −17]) compared with Set 1. In both sessions, RPE increased significantly in Set 3 compared with Set 1 (95% CI range = [0.68, 2.19]), while RTL decreased significantly from Set 3 (95% CI range [−2.99, −0.58]) compared to Set 1. Interset rest period and power output demonstrated fair reliability between sessions (mean intraclass correlation coefficient = 0.55), while RPE and RTL demonstrated good and excellent reliability, respectively (mean intraclass correlation coefficient = 0.63 and 0.80). In conclusion, highly trained strength athletes demonstrated a significant difference in their between session power output and total rest time when using self-selected interset rest periods, despite stability in their subjective ratings of fatigue and effort. Interset rest periods can be self-selected reliably to complete strength training in heavy squat protocol; however, power output may decline during the set.

Purpose The purpose of this study was to evaluate the reliability and validity of the Kannada version of the Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V). Method The Kannada version of CAPE-V comprises six phrases that are phonetically designed as per the CAPE-V requirements. Sixty-five (21 individuals with dysphonia and 44 asymptomatic) participants were enrolled for the instrument psychometric validation. The interrater and intrarater reliability as well as validity were assessed. Results High level of agreement was noted between the three raters across all the CAPE-V parameters, highest for pitch (intraclass correlation coefficient value = .98) and lowest for loudness (intraclass correlation coefficient value = .96). High intrarater reliability agreement (intraclass correlation coefficient value > .97) was also noted for all the parameters. Among the correlation for parameters that are comparable between CAPE-V and the Grade, Roughness, Breathiness, Asthenia, and Strain scale, the highest correlation was noted for overall severity. There was a significant difference noted between the study and control groups for all parameters except loudness. The discriminant function analysis and classification revealed that 98% were correctly identified. Conclusion The Kannada version of CAPE-V has been proven to be a psychometrically reliable and valid tool to use for auditory-perceptual evaluation of voice.
