- Effects of sleeping position on back pain in physically active seniors: A controlled pilot studyPublication . Desouzart, Gustavo; Matos, Rui; Melo, Filipe; Filgueiras, ErnestoBACKGROUND: The increase in life expectancy of elderly population has aroused the interest of different knowledge areas in understanding the variables that are involved in the aging process, linking them to other concepts such as active aging, healthy aging and the bio-psycho-social changes. OBJECTIVE: This paper presents the results of the first controlled, experimental pilot study that aimed to analyze the relationship between the perception of back pain and the sleeping position adopted by physically active female seniors. METHODS: Twenty female seniors (mean age 62.70 ± 3.827) participated in this study. The individuals were separated in 2 groups (Experimental and Control Group). For the carrying out of this study, the Visual Analogue Scale (VAS) was used to measure the intensity of back pain in the spine before and after four consecutive weeks an Intervention program. Individuals in the Experimental Group were instructed regarding the recommended way to sleep position (Intervention program) according to the pathological problems or the amount of pain reported. RESULTS: The Experimental Group (N= 10) presented significantly (p = 0.009) fewer complaints of back pain after an Intervention program in comparison to individuals who did not receive this type of information (Control Group).
- Human-Bed Interaction: A Methodology and Tool to Measure Postural Behavior during Sleep of the Air Force MilitaryPublication . Desouzart, Gustavo; Vilar, Ernesto Filgueiras; Melo, Filipe; Matos, RuiThe behavioral and postural habits and sleep rhythm of air force military change depending on the specialty work at the airbase or other types of events but we did not find anything in the literature to analyze and evaluate this behavior through sleep disorders. Perhaps this is related to the fact that the evaluation of this behavior is complex and the observation of these postural behaviors in the environmental context is needed. However the observation methodology based on ISEE software [9] allows the classification and registration of postural behaviors for long periods of time and can be applied in this context. This paper presents a study whose objective was to research the human interaction with postural behaviors during sleep in the residences' bedrooms of male air force military during the periods in which the subjects were asleep, awake, out of bed, doing activities, using a pillow in different time periods and with ecological validation with observation method and Visual Analogical Scale (VAS). A sample of 8666 observations, which corresponds to 240 sleep-hours of 12 air force military, was classified into six (6) Interaction Categories (IC). The results show that 50,2% of the participants presented the Lateral position (25,38% on the left and 24,86% on the right) as the most common postural behavior during sleep and 94,1% used only one pillow under their head. In the IĆs, the most common interactions were sleep period using the pillow with 66,47%, followed by category Out of bed with 25,32% and followed the category the activities and using the pillow with 6,95%. Findings of this study allow suggesting what graphical interface designers must seek as new strategies and solutions for behavior change in posture in bed, exploring other peripheral equipment for sleep position; or, at least, to improve the posture of the participants when using the number and the placement of the pillow in bed and if these Ergonomic changes can influence the reduction in back pain indications.
- Human-Computer Interaction in BedPublication . Desouzart, Gustavo; Filgueiras, ErnestoSleep disorders are increasingly common view and it is a growing problem in modern societies. There are several problems that can cause this type of disturbance, being the demanding obligations of work and study, a current problem, which leads individuals to allocate more time their rest period in at home. Currently, we are seeing the replacement of handwork by mental, automated and computerized work, which translates into an increasing percentage of time spent performing repetitive static character tasks (physical effort), being able to compare yourself to your work done in industry, traditional production lines (Caetano & Vala 2002). It is no less demanding contexts of labor among which are those activities that involve the long hours spent at the computer. This paper presents a study whose objective was to research the human-computer interaction with the time spent by young adults in carrying out activities with computing devices (computer, tablet or mobile phone) in residences’ bedrooms of air force military and university students in rest time periods and with ecological validation with observation method to video analysis and using a Software iSEE. A sample of 32956 observations, which corresponds to 1824 sleep-hours of 24 young adults, was classified into two (2) Interaction Categories (IC), body position while participants were awake in bed (2873 observations) and doing activities (3001 observations). The image registration was performed during the period of six months, divided into two periods with each participant, to enable the analysis of different times of the year and not just a single period can mean a higher specific activity. The results show that 38.7% (N = 1113 observations) of the participants presented the sitting as the most common postural behavior during awake in bed when the participants doing activities. In reference of activities in bed, 49.2% (N = 1475) used the computer, followed by Using mobile devices, with 16.7% (N = 501) of observations. When we analyze the group of participants, the students showed 49.2% of the period of activity in bed, using the computer, and 13.8% used mobile equipment. In the same reference, the military also used the computer (49%) as the main activity in bed during the night rest, but they used more mobile devices (19.4%) than students. Regarding the postures, students used the sitting (57.1%) as the main active posture when in bed, however, the military was the only sitting 3rd indication posture in bed, being the 1st observation of posture in bed,was the supine position with 30.7%. This data set the type of use of computer devices in bed (studying, playing games, watching movie or playing). Findings of this study allow suggesting what graphical interface designers must seek as newstrategies and solutions for posture in bed, exploring other peripheral equipment for using informatics equipment in bed position.
- Influence of Postural Intervention During the Sleep Period on Back Pain, Quality of Life and Sleep Quality in Young AdultsPublication . Desouzart, Gustavo; Filgueiras, Ernesto; Matos, RuiHuman health may have several problems that occur when sleep disturbances are verified, causing a loss in the quality of life, autonomic dysfunction and decreased professional or academic performance. Objective: The aim is check if the ergonomic intervention can mean positive changes in the indices of back pain (BP) complains, quality of life (QOL) and sleep quality (SQ) in young adults. Methods: A sample of 21,560 observations (595 sleep hours) of 24 young adults (12 male military and 12 female undergraduate) were separated in three groups (Experimental [EG], Placebo [PG] and Control [CG]). The sleep behavior was classified into two Interaction Categories according to the iSEE methodology observation. For the carrying out, the Visual Analogue Scale, the abbreviated questionnaire of World Health Organization on quality of life and the Pittsburgh Sleep Quality Index was used before and after an ergonomic intervention program by physiotherapy. Results: EG improved self-perception of SQ (p = 0.008), QOL (p = 0.000), reduce the level of BP (p = 0.001) and change for an ideal posture while sleeping. Conclusion: The findings of this study allow us to suggest to health care professionals, in particular the rehabilitation professionals, new strategies for ergonomic postural behavior.

- Postural Education: Correlation Between Postural Habits and Musculoskeletal Pain in School Age ChildrenPublication . Desouzart, Gustavo; Filgueiras, Ernesto; Matos, Rui; Dagge, RicardoThe best way to avoid poor postural habits, is to teach children good postural behaviors for performing their everyday life activities (Verderi in Programa de educação postural, 2011 [1]). Despite the existence of specific programs, intended for children’s self-body consciousness improvement, Physical Education curricula lack this type of exercises (Braccialli and Vilarta in Revista paulista de Educação Física 14: 159–171, 2000 [2]; Costa and Freire in Estudo dos exercícios físicos voltados para correções das alterações posturais, 2004 [3]; Ramos and Rodrigues in EFDeportes.com, 2013 [4]). Attended by 220 students, with ages between 10 and 15 years old, this study applied a technique (Corlett and Bishop in Ergonomics 19:175–182, 1976 [5]) for assessing postural discomfort, and an informal questionnaire (Carmo et al. in Metodologia da Investigação – Guia da Auto-aprendizagem, 1998 [6]; Rebolho in da educação postural nas mudanças de hábitos em escolares da 1ª a 4ª séries do ensino fundamental, 2005 [7]), to fully understand pain and postural discomfort felt by Portuguese school age children. Results showed: a significant direct correlation between the time, and the perceived intensity of pain felt, for chronicle and acute pain; regarding postural habits, 88.5 % of subjects presented some kind of inadequate postures, perceiving significantly higher pain. Major findings, allow us to raise the awareness for postural education programs introduction in Physical Education curricula, since they could influence children’s physical health.
- Relation between musculoskeletal pain and postural habits in female students of elementary schoolPublication . Desouzart, Gustavo; Matos, Rui
- Relationship between Postural Reeducation Technique During Sleep and Relaxation Technique in Sleep QualityPublication . Desouzart, Gustavo; Filgueiras, Ernesto; Matos, RuiThe common sense warn that the quality of our day depends on the quality of our previous night. Among the main factors contributing to a better sleep quality is the postural behavior during the sleep period. However, little or nothing is known about the actual influence of these behaviors on people sleep quality. This paper presents a study which aims to: i) Check if people can take on a new postural behavior during the sleep period after a training period aware of this behavior and; ii) Check if a postural recommendations can aims to induce positive changes in the perception on the indices of Sleep quality in young adults, according to ecological and environmental approach. A sample of 21560 observations, which corresponds to 595 hours of sleep hours of 24 young adults, 12 male military and 12 female undergraduate, participated in this study. The Pittsburgh Sleep Quality Index (PSQI) was used to measure the perception of sleep quality before and after six consecutive months of appliance of the Postural Intervention program. Results shown that the Postural reeducation group improved self-perception of sleep quality (from bad to good) and a significant difference between the periods of the study (p = 0.008), according to the Student's T-Test and, ideal posture while sleeping using the ideal placement and amount of pillows (1.34% to 81.48%). Findings of this study allow us to suggest to health care professionals, in particular the rehabilitation professionals, new strategies and solutions for ergonomic change in posture in bed and improve the sleep quality indices.
- Understanding the Interaction of Design Students with Portable Computers in the ClassroomPublication . Lavin, Luís; Filgueiras, Ernesto; Figueiredo, Carlos; Desouzart, GustavoLaptop computers are an indispensable tool for the learning of Product Design. However the universities classrooms are not adapted to the new technological evolutions and working processes. The main objectives of this study were to analyze the human-computer interaction in Product Design classrooms, by observing the users, the work activity and the environment, to understand the current demands for the use of laptop computers, and to observe current patterns of student interaction, and their needs. Data were gathered and analyzed from a set of classrooms in a Portuguese university using the following methodologies: free observation; systematic indirect observation through video recording and analysis; and student survey. The results show that 56.5% of the study participants use information systems in the classroom, of these, 90% use laptop computers, and use this devices individually. In general, about 52% of the records indicate that in the classroom the information systems were used by less than 50% of the class students. This study results can promote: (a) the development of a set of data and information that can assist designers and other professionals in the product creation process; (b) the awareness of the universities to the need to modernize the spaces, furniture, and equipment, and to adapt them to the new processes of work and to the new student-computer interactional behaviors.
