“…Regarding the methodological aspects, in the present study, instructions regarding where to look, posture and gait were not performed, which is in agreement with previous studies [20,22,23]. It is noteworthy that laboratory analysis alone modifies patterns of posture and movement, known as the Hawthorne effect [24].…”

Introduction: Postural control is a multidimensional construct modulated by the integration of sensory information and muscular activity. One of the challenges in clinical practice and scientific research is the postural data collection of objective control data. Thus, baropodometry can be a promising instrument for analysis. Objective: To evaluate the absolute and relative reliability of baropodometry by means of test-retest in young asymptomatic subjects during semi-static and dynamic analysis. Methods: This is a methodological study, approved by the Research Ethics Committee of UFJF (1,803,411). Sample selection was performed by convenience. Healthy individuals aged 18 to 35 years were included in the study without gender restriction. Participants with pain or any clinical signs of overload which led to unfeasible collection were excluded from the analysis. The variables analyzed were contact surface, maximum and mean pressure, index bow, pressure center and pressure areas in the forefoot, midfoot and hindfoot. Results: 33 individuals (total of 66 feet) participated in this study. The mean body mass of the participants was 63.0 ± 9.9kg, height of 163.4 ± 30.1cm, BMI of 23.7 ± 2.8 kg/m2. It was observed that five out of the eight variables evaluated in the semi-static analysis presented high reliability (≥ 0.70). On the other hand, the reproducibility of the measures in the dynamic analysis was low to moderate (≤ 0.69). Conclusion: Baropodometry findings should be interpreted with caution in clinical practice and in scientific research. It is suggested that complementary assessments be made for decision-making assistance.

“…Here, Perinetti et al 56 confirm an acceptable reliability for the sway area and velocity, but recommend to include a threshold of 25%, if at least two different conditions are to be compared with each other. Intersession reliability was also proven by Baldini et al 57 For the ‘S-Plate’, a pressure measuring platform similar to the one used here with a larger sensor size and smaller number of sensors, good reliability and reproducibility could be observed 58. Consequently, the pressure platform is suitable to represent postural standard values, but it must be considered that the sensors are temperature-sensitive.…”

ObjectiveMany people of all ages suffer from vertigo due to different reasons. The comparison of patient data with standard values can highlight deteriorations or changes in postural control and thus indicate, for example, an increased risk of falling. Our aim is to measure standard values for the postural control of young healthy women.DesignObservational study.SettingInstitute of Occupational Medicine, Social Medicine and Environmental Medicine, Goethe-University Frankfurt/Main.Participants106 healthy German female subjects aged between 21 and 30 years (25±2.7 years) were measured. Their average body mass index (BMI) was 21.1±2.61 kg/m².Outcome measuresA pressure measuring platform was used to measure the weight distribution and postural sway in habitual standing. Median, tolerance range and CI were calculated.ResultsHeight, weight and BMI are comparable to the average young German female population. The load distribution between right and left foot was 49.91%:50.09%. The forefoot was less loaded than the rear foot (33.3%:66.67%). The right rear foot carried most of the body weight (34.34%). The average body sway was 9.50 mm in the frontal and 13.00 mm in the sagittal plane.ConclusionsStandard values for the postural control of the women aged 21–30 years correlate with the already collected data of healthy subjects and can therefore be described as representative. The standard values enable diagnosing and treating impaired balance.

“…All ICCs were greater than 0.9 for all measured dynamic variables and the highest CoV was 1.7%, which was concordant with the outcomes from previous studies. 22,25,43 We did not find any significant differences between the first and second sessions when comparing means, with P-values > 0.05. All of the variables evaluated were highly homogeneous across all LLD conditions and for both feet.…”

“…These results indicated that the reliability measurements were higher than those in other similar studies. 22,43 One explanation for this may be that the measurements were obtained using the multiple dynamic mode of the platform. In this mode, the platform software automatically provides the average results from four measurements for each foot.…”

BACKGROUND: Leg length discrepancy (LLD) may play a key role in exercise biomechanics. Although the Podoprint platform has been used in dynamic pressure studies, there are no data regarding the reliability and repeatability of dynamic measurements under simulated LLD conditions. OBJECTIVES: To determine the intra and intersession repeatability and reliability of dynamic parameters of the Podoprint pressure platform under simulated LLD conditions. DESIGN AND SETTING: Observational cross-sectional study at a public university. METHODS: Thirty-seven healthy volunteers participated in this study. LLD was simulated using ethyl vinyl acetate plantar lifts with heights of 5 mm, 10 mm, 15 mm and 20 mm located under the right shoe of each volunteer. The procedure was performed to capture the dynamic parameters of each participant under five different simulated LLD conditions. Stance time, mean pressure and peak pressure measurements were registered in three trials for each foot and each LLD level. Data were collected during two separate testing sessions, in order to establish intrasession and intersession reliability. RESULTS: The intraclass correlation coefficients (ICCs) for intrasession reliability ranged from 0.775 to 0.983 in the first session and from 0.860 to 0.985 in the second session. The ICCs for intersession reliability ranged from 0.909 to 0.990. Bland-Altman plots showed absence of systematic measurement errors. CONCLUSIONS: The results from this study indicate that the Podoprint platform is a reliable system for assessing dynamic parameters under simulated LLD conditions. Future studies should evaluate plantar pressures under LLD conditions, in association with exercise, biomechanics and musculoskeletal disorders.
