AbstractIntroduction. Many studies have compared different backpack designs and their influence on the carrier; however, no data referring to school students aged 7-8 years are currently available. Therefore, the aim of the research was to assess the influence of backpack design on centre of pressure (COP) displacement and plantar force distribution in children during an upright stance. Material and methods. Nineteen school students (9 males and 10 females) volunteered for the study. Two Polish backpacks intended for school use were evaluated: backpack A, which had two main compartments, and backpack B, which had one main compartment. The backpack load was composed of books, binders, and regular school equipment. During the measurements, the subjects were asked to look ahead with the head straight and arms at the sides in a comfortable position and to stand barefoot on the F-Scan®sensors (Tekscan, F-Scan®) attached to the force platform (Kistler), carrying a load corresponding to 10% of their body mass. Results. The study found insignificant differences between the two backpack designs. Moreover, COP parameters increased significantly during an upright stance while carrying backpack B in comparison to the empty backpack condition. Additionally, we observed significantly higher values of plantar force distribution in the heel region for the condition without load and insignificantly higher ones for carrying backpack A. Conclusions. The results of the current study suggest that the differences between the two backpack designs are too marginal to be detected through COP displacement. Disturbances in plantar force distribution suggest a lack of posture control and a lower stability of the standing position with a backpack, but these disturbances were significant only when the backpack with one main compartment was used.

Background We aimed to determine the center of pressure (COP) trajectories and regional pressure differences in natural rearfoot strikers while running barefoot, running with a minimalist shoe, and running with a traditional shoe. Methods Twenty-two male natural rearfoot strikers ran at an imposed speed along an instrumented runway in three conditions: barefoot, with a traditional shoe, and with a minimalist shoe. Metrics associated to the COP and regional plantar force distribution, captured with a pressure platform, were compared using one-way repeated-measures analysis of variance. Results The forefoot contact phase was found to be significantly shorter in the barefoot running trials compared with the shod conditions (P = .003). The initial contact of the COP was located more anteriorly in the barefoot running trials. The mediolateral position of the COP at initial contact was found to be significantly different in the three conditions, whereas the final mediolateral position of the COP during the forefoot contact phase was found to be more lateral in the barefoot condition compared with both shod conditions (P = .0001). The metrics associated with the regional plantar force distribution supported the clinical reasoning with respect to the COP findings. Conclusions The minimalist shoe seems to provide a compromise between barefoot running and running with a traditional shoe.

Integrating socio-economic dimensions in ecosystems analysis and management is becoming increasingly important, particularly from a mapping standpoint. A key challenge with such integration is reconciling different geospatial representations based on census and administrative frameworks with natural ecosystems boundaries.This article presents one method for addressing this challenge by mapping an information rich 'ecumene'. In this approach, communities are mapped as human habitats using natural boundaries as opposed to administrative-type boundaries, integrated with authoritative socio-economic data. To illustrate the benefits of this approach, two example applications are provided that: 1) map and estimate the population of the 'forest ecumene' of Canada, and 2) map labour force distribution patterns associated with the forest sector and its relation to forest areas in Canada. Benefits and limitations of this approach are discussed, from which a number of priority areas for future research are identified.

Pressure Analysis

We aimed to investigate whether troughing during scarf osteotomy for hallux valgus can be determined using plantar pressure analysis. In order to quantify the foot print area of a patient at 7 and 12 weeks after the surgery, the raw pressure data were exported to two matrixes. Each matrix has the size of the force distribution platform and contains the plantar force data of the patient in gait movement. These large matrixes containing both left and right pressure data were divided in small size matrixes and averaged. The computation was done in Matlab. The matrixes were flipped up in order to have the natural position of the footprint. The two were plotted as contours in Z axis but kept the external contours only. This difference was measured by subtracting the areas of the two contours. The results are typical footprints for left and right legs, at predetermined follow-up points.

This chapter describes the many clinical applications of Digital Occlusal Force Distribution Patterns (DOFDPs) recorded with the T-Scan Computerized Occlusal Analysis system. Movements made by the Center of Force trajectory as force travels around the dental arches during the occlusion and disocclusion creates these patterns. The repetitive occlusal contact data points locate the force distribution received when teeth occlude against each other. These force distribution patterns correlate to intraoral compromised dental anatomy found in radiographs, photographs, and during the clinical examination of teeth and their supporting tissues. Moreover, they directly influence the envelope of motion, the envelope of function, and head and neck posture. This chapter illustrates with clinical examples the correlation between Stomatognathic System structural damage and repeating patterns of abnormal occlusal force distribution. The T-Scan technology isolates these damaging regions of excess microtraumatic occlusal force, absent of clinician subjectivity, thereby helping clinicians make an accurate, organized, and documented occlusal diagnosis.
