title: Global soil saturated hydraulic conductivity map using random forest in a Covariate-based GeoTransfer Functions (CoGTF) framework at 1 km resolution

description: The global Ksat map at 1 km resolution was developed by harnessing the technological advances in machine learning and availability of remotely sensed surrogate information such as terrain, climate, vegetation, and soil covariates. We merge concepts of predictive soil mapping with a large data set of Ksat measurements and local information (soil, vegetation, climate) into covariate-based “Geo Transfer Functions'' (CoGTFs) to generate global estimates of Ksat values (to highlight the impact of Geo-referenced covariates including various remote sensing maps, we use the term Geotransfer function GTF and not pedotransfer function PTF; in the latter case, typically only soil properties are used to estimate Ksat). The Ksat dataset is provided in GeoTIFF format. A total of 4 files that represent different soil depths (0, 30, 60, and 100 cm) are provided. The Ksat values are log-transformed (log10 Ksat) and cm/day was selected as a standardized unit.

title: Relation of functional capacity, strength and muscle mass in elderly women with osteopenia and osteoporosis

description: This study aimed at analyzing the association among functional ability tests, performance of knee muscles, and body composition of elderly women with low bone densities. A transverse study with 48 elderly women (aged 70.62±5.95 years) was developed, and their functional abilities were evaluated (Timed Up and Go - TUG - and Chair Stand - CST - tests), as well as their knee muscle performance (isokinetic dynamometer), their muscle mass (skeletal muscle index with BIA), and their lean mass (skin folds). The majority of the sample was active or moderately active (95.8%), was found to be overweight (68.75%), was not found to have sarcopenia (62.5%), and had average performances of 7.7 seconds in TUG and 11.21 seconds in CST. The functional ability was found to have moderate and low negative correlations with the knee muscle performance variables. Their muscle mass was found to have a low positive correlation with the power of knee extensor muscles and it was found to have no correlation with the functional ability, which was only found to have an association with the muscle performance, which reinforces how unreliable it is to use muscle mass as the single measurement for the identification of sarcopenia.

title: Electromyographic activity and cocontraction of trunk muscles during exercises performed with an oscillatory pole: an analysis of the effect of different postures

description: This study aimed at analyzing the electromyographic activity (EMG) and cocontraction of torso muscles during exercises with a flexi bar, in two different postures (neutral pelvis and posterior pelvic tilt). 20 young women with no lower back pain took part in the study (ages between 18 and 28 years) and they were recruited from a university population. In order to collect the data, an exercise was performed with a flexi bar being held with both hands. It was perpendicular to the ground and it was oscillating in the sagittal plane. That exercise was conducted in two different pelvis postures (neutral and posterior tilted). The EMG signals were collected bilaterally on the following muscles: internal oblique (IO), rectus abdominals (RA), iliocostalis lumborum (IL) and multifidus (MU). The analysis of variance (ANOVA) of repeated measurements was found to display an interaction between muscles and postures (F=5.18; p=0.003). The activation of IL muscle in the neutral posture was 7.93% higher than in the posteriorly tilted posture (p=0.005), and the activation of IO muscle was 13.62% higher in the posteriorly tilted posture than during the exercise in the neutral posture (p=0.002). According to our results, the performance of the exercise with a posteriorly tilted pelvis increased the activation of IO muscle, whereas IL muscle was found to have a higher activation when the exercise was performed in a neutral posture. Future studies need to be conducted in order to understand the neuromuscular adaptations that are generated by exercises with flexi bars, and their relevance to the prevention and treatment of nonspecific lower back pain.

title: Is optoelectronic plethysmography a valid instrument to measure inspiratory capacity?

description: The aim of this study was to evaluate the concurrent validity of the optoelectronic plethysmography (OEP) to measure inspiratory capacity (IC) at rest and during submaximal exercise in healthy subjects. Twelve subjects (6 Male/6 Female; 23.8±1.34 yrs) with normal body mass index and lung function completed the study protocol. Participants were assessed at rest and during a 12-minute submaximal exercise protocol on a cycle ergometer. IC maneuvers were simultaneously recorded by OEP system and by a spirometer at rest and during exercise. The percentage of discrepancy between measurements, linear regression analysis and Bland-Altman method were used for data analysis. The study was approved by the institution ethics committee. It was considered 150 valid IC maneuvers for analysis (44 for resting and 106 for exercise). The percentage of discrepancy between the measurements were -9.6 (8.6%) at rest and -4.6 (5.5%) during exercise. Regression analysis showed good linear associations between methods at rest (r2=0.90; p=0.0002) and during exercise (r2=0.96; p=0.0008). Bland-Altman analysis using data obtained during exercise showed a bias between the two methods of 0.13L. The limits of agreement indicate that the difference between methods can vary from -0.04L to 0.57L. Additionally, data was equally distributed between the upper and lower limits, demonstrating no systematic overestimation or underestimation of the IC by any of the instruments. In conclusion, this study demonstrated that the OEP is a valid evaluation system to measure IC of healthy individuals at rest and during submaximal exercise.

title: Analysis of functional status of elderly with osteoarthritis

description: The objective of this study was to analyze the influence of gender, age and pharmacological treatment for osteoarthritis (OA) on the functional status of physically independent elderly. This cross-sectional study involved 105 elder individuals from both genders (age: 68.80±6.3 years) with OA of the hip and / or knee, which was confirmed by radiographic analysis. Two specific instruments assessed functional status: Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Lequesne Index. It was observed worse condition in females in Lequesne (p=0.007), global WOMAC (p=0.013), as well as in its fields: pain intensity (p=0.023), stiffness (p=0.032) and functional status (p=0.018). However, considering age and radiological status, no differences were observed between groups in all variables (p&gt;0.05). It was observed that the individuals with pharmacological treatment for OA have poor functional status in all functional questionnaires (Lequesne, p=0.005; global WOMAC, p=0.008 as well as in specific WOMAC fields, such as Pain intensity, p=0.004; Stifness, p=0.007; and Functional status p=0.023). At multivariate modelo (multiple linear regression), it was observed that gender and pharmacological treatment may influence the functional status of elderly with OA, whereas women and medicated individuals are those showing the worse condition both in Lequesne and WOMAC indexes. It was observed worse functional status in women with osteoarthritis and pharmacological treatment evoked no improvement in functional status of these individuals.

title: Reference values of ultrasonographic measurement of cross-sectional area of the multifidus muscle in children aged 6 to 9 years

description: This study aimed to provide reference value measures from the cross-sectional area (CSA) of the multifidus muscles in children aged 6 to 9 years old. For this purpose, 41 children (20 boys and 20 girls) were interviewed about their physical exercises practice and submitted to a unilateral ultrasonographic evaluation from the CSA multifidus muscles at rest, in the level of L5, and to an anthropometric evaluation (weight, height and MMI - muscle mass index). An average of CSA from the multifidus was found from 3,11±0,84cm² with no difference between sexes (p=0,37) and between sedentary children and regular exercise practitioners (p=0,68). However, it was detected a positive correlation between the CSA and the age (r=0,75; p&lt;0,01), the weight (r= 0,83), the height (r= 0,75; p&lt;0,01) and the MMI (r=0,54; p&lt;0,01). Thus, the CSA of the multifidus of this study showed a tendency of great dimension according to the age increase, weight, height and MMI.

title: Q angle and subtalar pronation are not good predictors for pain and function in subjects with patellofemoral pain syndrome

description: The aim of this study was to evaluate the capability of Q angle and subtalar pronation clinical tests in predict pain and functional limitations reported by individuals with patellofemoral pain syndrome (PFPS). 31 individuals with PFPS were recruited for this study. The Anterior Knee Pain Scale questionnaire was applied to identify the functional limitations and the Visual Analogue Scale was used to identify the pain referred during the last month. Two clinical tests were performed in order to obtain the Q angle and subtalar pronation measurements. The values of the tests were entered in a multiple and linear regression models to obtain the R2 and the regression coefficients for non-continuous standardized measures, with a statistical significance set at α=0.05. Both tests, when entered separately into the linear regression models achieved low values of pain and function prediction. On the other hand, when placed together in a multiple regression model, the tests explained 9% and 4% of the pain and functional limitations of the individuals with PFPS, respectively. Although there was an improvement in the pain and function limitation prediction when the tests were analyzed together, our findings showed that both measurement, Q angle and subtalar pronation, are not good predictors of pain and functional limitations of individuals with PFPS.
