[Thésaurus Mesh]Poids et mesuresMots-clés : Orbscan Résumé : SIGNIFICANCE: This study obtained normative database for angle κ using Orbscan 3. The average angle κ values were 2.3 ± 1.34° in the whole sample, 2.23 ± 1.36° in myopic eyes, and 3.3 ±1.5° in hyperopic eyes. This is very important to optimize refractive surgery outcomes. PURPOSE: The aim of this cross-sectional study was to obtain the value of mean angle κ in normal eyes of patients seeking laser vision correction, by the Orbscan 3. METHODS: The study was conducted on healthy eyes of people seeking laser refractive surgery. A total of 1815 eyes of 908 candidates were included. These were examined as a part of pre-operative assessment. Orbscan 3 was used to measure angle κ and its XY intercepts, keratometry readings, central corneal thickness, thinnest location, white-to-white diameter, and corneal asphericity of front surface (Qf ) and back surface (Qb). RESULTS: The mean ± standard deviation angle κ in all eyes was 2.3 ± 1.34°. The values were 2.23 ± 1.36° in myopic eyes, 3.3 ±1.5° in hyperopic eyes, and 2.9 ±1.6° in emmetropic eyes. Positive correlation was found between angle κ and age, spherical equivalent, subjective sphere, and white-to-white diameter. On the other hand, axial length, average keratometry, central corneal thickness, pupil diameter, and asphericity Q front were negatively correlated with angle κ. CONCLUSIONS: The mean ± standard deviation angle κ value measured by the Orbscan 3 was 2.3 ± 1.34°. This could be attributed to different software used, in addition to the relatively high axial length in the studied eyes.

[Thésaurus Mesh]Poids et mesuresMots-clés : hauteur rigidité Résumé : Background: Studies of arch height index (AHI), arch rigidity index (ARI), and arch stiffness have primarily focused on healthy populations. Normative values of the aforementioned measurements in a pathologic sample may be useful in identifying relationships between arch structure and pathology.
Methods: AHI was obtained bilaterally at 10% and 90% weightbearing conditions using the AHI measurement system. ARI and arch stiffness were calculated using AHI measurements. Dependent t tests compared right and left, dominant and nondominant, and injured and noninjured limbs. Dominant feet were compared between sexes using independent t tests. Relationships between arch stiffness and subcategories were examined using the coefficient of determination (R2). One-way analyses of variance determined differences between arch structure and number of pathologies or body mass index (BMI).
Results: A total of 110 participants reported one (n = 55), two (n = 38), or three or more (n = 17) pathologies. Plantar fasciitis (n = 31) and hallux valgus (n = 28) were the most common. AHI, ARI, and arch stiffness did not differ between limbs or sexes for any comparisons. Between subgroups of BMI and number of pathologies, BMI influenced AHI (10% weightbearing) and arch stiffness (P < .05). Arch stiffness showed a weak relationship to AHI, where a higher AHI was associated with a stiffer arch (R2 = 0.06).
Conclusions: Normative arch structure values were established in a pathologic sample with a large incidence of plantar fasciitis and hallux valgus. Understanding relationships between arch structure and pathology is helpful for clinicians and researchers.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

This study demonstrated that a semiautomated segmentation method could help inexperienced practitioners to obtain choroidal thickness as good as experienced practitioners.
PURPOSE
The purpose of this study was to compare choroidal thickness measurements obtained by semiautomated and manual segmentation methods.
METHODS
Optical coherence tomography images of 37 eyes from 37 healthy young subjects acquired by a spectral-domain optical coherence tomography device were reviewed retrospectively. Two naive examiners measured choroidal thickness using manual and semiautomated methods, whereas two experienced examiners used only the semiautomated method. The semiautomated method referred to a fully automated segmentation program customized based on MATLAB and followed manual verification. After highlighting the inner and outer choroidal boundaries through automated segmentation, examiners reviewed these boundaries in each B-scan and conducted manual revisions if segmentation errors occurred. After selecting points where correct boundary was located, the software used a spline fit to blend the corrected region with the rest of the boundary. All measurements were summarized in a 6-mm Early Treatment Diabetic Retinopathy Study grid. Operation time spent to complete retinal and choroidal segmentation on each eye was recorded. Between-examiner agreements, that is, intraclass correlation coefficient and coefficient of reproducibility (CoR), were calculated among four sets of semiautomated measurements, and within-examiner agreements were comparisons between manual and semiautomated results from the same naive examiners. Eyes with thin or thick choroids were also analyzed separately.
RESULTS
The between-examiner and within-examiner agreements were excellent with intraclass correlation coefficient of 0.976 or greater. Pairwise within-examiner CoRs ranged from 17.4 to 47.1 μm. Pairwise between-examiner CoRs were between 13.0 and 38.9 μm. Eyes with thin choroid had better agreements than those with thick choroids. On average, naive examiners saved 3 to 5 minutes per eye using the semiautomated method.
CONCLUSIONS
With the help of a dedicated software, inexperienced practitioners could obtain choroidal thickness measurements with accuracy similar to experienced practitioners. Processing time with the semiautomated method was also reduced..

[Thésaurus Mesh]Poids et mesuresMots-clés : dorsiflexion Dorsi-Meter Résumé : Background: Ankle joint dorsiflexion range of motion is essential to normal gait. Ankle equinus has been implicated in a number of foot and ankle pathologies included Achilles tendonitis, plantar fasciitis, ankle injury, forefoot pain, and foot ulceration. Reliable measurement of ankle joint dorsiflexion range of motion, both clinically and in a research setting, is important. Methods: The primary aim of this study was to investigate the intertester reliability of an innovative device for measuring ankle joint dorsiflexion range of motion. A total of 31 (n = 31) participants volunteered to take part in this study. A paired t-test was performed to assess for systematic differences between the mean measures of each rater. Intertester reliability was evaluated using the intraclass correlation coefficient (ICC) and their 95% confidence intervals. Results: A paired t-test demonstrated that the mean ankle joint dorsiflexion range of motion did not significantly differ between raters. The ankle joint ROM mean for rater 1 was 4.65 SD (3.71) and rater 2 was 4.67 SD (3.91). Intertester reliability for the use of the Dorsi-Meter was excellent and demonstrated a very narrow range of error. The ICC (95%CI) was 0.991 (0.980 to 0.995) the SEM (in degrees) was 0.07, the MDC95, in degrees was 0.19 and 95% LOA, degrees was –1.49 to 1.46. Conclusions: We found the intertester reliability of the Dorsi-Meter to demonstrate higher levels of intertester reliability compared to previous studies investigating other devices. We reported the MDC values to provide an estimate of the smallest amount of change in the ankle joint dorsiflexion range of motion that must be achieved to reflect a true change, outside the error of the test. The Dorsi-Meter has been established as an appropriate reliable device to measure ankle joint dorsiflexion for clinicians and researchers with very small minimal detectable change and limits of agreement Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires

The neutral calcaneal stance position (NCSP), despite its known issues, is currently used as an “ideal” measure compared with the resting stance position in clinical podiatric medicine. The nonweightbearing (NWB) foot position, as used in the foot mobility magnitude (FMM), can provide an alternative comparative position, which is partially validated, if a significant correlation between the NCSP and the NWB position exists. This study aimed to establish the correlation between the component measures of the FMM in the NCSP and the NWB foot position of the FMM.
Methods
Eighty participants were recruited. Measures of dorsal arch height (DAH) and midfoot width (MFW) were obtained at the 50% total foot length mark in the NCSP and the NWB position by two examiners using the apparatus described by McPoil et al.
Results
Reliability analysis with intraclass correlation coefficients (ICCs) indicated intrarater results of 0.90 to 0.99 for DAH and 0.96 to 0.99 for MFW and interrater results of 0.90 for DAH and 0.96 for MFW in the NWB position. Using a Pearson product moment correlation coefficient analysis, there was a significant correlation between the NCSP and the NWB position for DAH (r = 0.82) and MFW (r = 0.86).
Conclusions
A significant correlation between the NCSP and the NWB position was evident when the measures of DAH and MFW were conducted. Therefore, clinically, the NWB position can potentially replace the NCSP as the ideal position for clinical treatment.Permalink : https://bibliotheque.helb-prigogine.be/opac_css/index.php?lvl=notice_display&id= [article]Exemplaires
