Distribution of Foot Pressure reflects the deformations of body biomechanical design. They are caused by different reasons: degenerative, by trauma, etc., being flat foots a common pathology in Peru with high incidence. However there isn't the properly technology to detect properly this disease because is detected by a non-reliable visual way using pedoscopes. Flat foot is the degree of internal plantar arch lack and is well observed in foot pressure distribution. This distribution can be obtained by optical or electronic systems. The most required, by their accuracy, are the electronic ones but sensor manufacturing process increases its price, meanwhile optics provides an indirect optical solution whose price depends on scanners resolution. Therefore, this paper takes advantage of both systems: a direct pressure value from electronics and no problems calibration from optical systems. In regard of these reasons, prototype will use a webcam and twelve FSR (Force sensing resistor) sensors including estimation techniques, and thus obtain the foot pressure distribution. Accordingly, the present study is looking for providing to the specialist with an efficient tool to generate better diagnostics in Perú.
Background: : Limited research has been conducted that explores the occupational experience of hearing voices, including the impact it has on romantic and/or sexual relationships. This study aims to address this gap by capturing the experience of romantic and sexual relationships for those who hear voices. Method: : A phenomenological approach was used to gather data from a survey, electronic diaries, and interviews of three voice hearers who were interested or actively in a casual or serious relationship. Results: : All of the participants reported that the voices in some way impacted their past or current romantic and sexual relationships. The dynamic relationship between voices and occupation could directly or indirectly impact the experience of occupation with their partner. Voices with personas were found to have varying levels of participation in occupations, with some becoming co-occupations between the participant and their voices. Support from their partner was valued, though varied by participant, with some of the participants seeking outside support from peers with shared experiences. Conclusion: : This research challenges the idea of the individual having full agency during occupational performance. Because voices can actively participate during co-occupations, occupational therapists need to inquire about their voices during evaluation and include them during interventions. Comments The authors report no potential conflicts of interest.
The objective of this work is to study and design a portable non invasive prototype which allows us to supervise the mastication frequency and pressure for specific meals, performing an analysis of sounds and pressures generated by facial muscles when they are chewing. These variables have a direct influence on people nutritious and dietary habits; also, a quickly eating makes people ingest a lot of food instead he needs generating overweight on him. On the other hand, there is no so much study for upheaval of temporal-mandible joints (TMJ) in Peru, keeping as reference that unilateral mastication is one of the principal causes on myofacial pains but, as obesity, there are no studies in Peru about how to prevent these pathologies. In consequence, we propose the development of this prototype which, additional to supervise variables such as mastication frequency and pressure, will allow to the patient an self-correction of his habits.
Conducting research and development activities generates new knowledge that can then be applied properly. In this sense, the groups of research and development on biomedical engineering (GRDBE) can contribute a lot in various areas such as teaching (theory and laboratory), as well as the development of prototypes, but mainly with the results they can provide. These contributions should response to specific needs of some sector, for example: health, environment, biology, and others. The present paper provides a description of the development of a GRDBE into a private university. Also, it's presented the amount of papers developed by this group and accepted by international congress on biomedical engineering (BE) on the 2007-2009 period. This paper also shows comparative charts with papers produced by other GRDBE that exist in our country, which are matter of analysis and conclusions.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
