Postura sentada: a eficácia de um programa de educação para escolares

Avaliação da eficácia de um programa de educação sobre o conhecimento relacionado à postura sentada de estudantes da 1ª série do ensino fundamental, na esfera estadual, particular e municipal, em Bauru. Foram avaliados (pré-teste) 71 alunos e depois aplicado um programa de educação sobre o tema, composto de aulas expositivas, técnicas de demonstração e feedback, associado a um programa de reforço ministrado por professoras treinadas e, finalmente, a reavaliação (pós-teste) dos conhecimentos dos participantes. Foi observado que: 1) no pré-teste ocorreu diferença significativa entre as escolas, sendo que a municipal apresentou menor número de erros do que a particular e a estadual; 2) o pós-teste mostrou que houve diferença significativa sendo que as escolas municipal e particular tiveram um menor número de erros em relação a estadual; 3) em todas as escolas houve predominância da situação de erro pré-teste maior que pós-teste. A escola estadual tem resposta mais freqüente que a particular quando há aumento de erro. Conclui-se que o programa se mostrou eficaz para aumentar os conhecimentos dos escolares a respeito da postura sentada.

The influence of the flexibility of the chair seat on pressure peak and distribution of the contact area in individuals with cerebral palsy during the execution of a task

This study aimed to determine the influence of flexibility of the chair seat surface on the pressure peak and on the contact area during the execution of a task of handling an object on the seated position by individuals with spastic cerebral palsy. Ten individuals of both genders with diagnosis of spastic cerebral palsy, who had some control to voluntarily move the body and the upper limbs, participated in this study. Quantification of data was carried out in two experimental situations: (1) execution of a task of fitting with upper limbs, and with the individual placed on an adapted canvas seat; (2) execution of a task of fitting with the participant positioned on an adapted wooden seat. Data obtained were submitted to a non-parametric and descriptive statistical analysis using the Wilcoxon test. Results indicated that the use of canvas seat increased the contact area and decreased the pressure peak and the medio-lateral displacement of centre pressure on the seated posture. © 2011 Informa UK, Ltd.

Comfort, stability and body posture in wheelchair cushions: a preliminary study with able bodied subjects

Long term wheelchair usage has been related to a number of problems, among which pressure ulcers are one of most concern. The design of wheelchair seat cushions has been of increasing interest among researchers, as it can influence seat interface pressure and user's comfort. The aim of this study was to investigate the subjects' perception comfort, stability and body posture of six different commercially available wheelchair cushions. The evaluation was through a questionnaire, where the subjects rate their perceptions on a ten point visual analog scale after staying seated in the cushion for two minutes. The results shows that the Roho^TM aircell cushion was preferred by the users, while the least preferred one was the water cushion. Individuals' subjective perceptions may compliment objective data on seat interface pressure, thus contributing to a more complete view of the users' experience during wheelchair cushion usage.

Electromyographic study in Erector spinae, Rectus abdominis, Glutaeous maximus and Rectus femuris muscles, in standing and static posture with load on hands

Observe the loads associates application with in position of body, in the static or dynamic postures. Methods: the electromyographic study in erector spinae, rectus abdominis, glutaeous maximus and rectus femoris muscles was accomplished in female volunteers from 18 have 27 years old, previously selected. The muscles electric activities was gotten with surface electrodes, in standing and static posture, with the parallels and horizontal upper limbs with load on their hands. Conclusion: In this study it was clearly observed influence of the load and distance there is over studied musculature associated with standing erect posture.

Comparative study on the posture of individuals with and without cervical pain

Posture can be defined as the overall position and spatial orientation of the human body and its members relative to each other. The study of posture can be applied either static, with the subject standing still. Objectives: to identify and quantify the static posture alignment of individuals who were either symptomatic or asymptomatic for cervical pain. Methods: A cross-sectional study was carried out on subjects with cervical pain and individuals with no complaints of pain. The procedure consists in placing markers on specific points. Several views, following the protocol of the Posture Assessment software, regarding the measurement of angles (in degrees) and differences in lower leg lengths (in centimeters). Angles were analyzed through the comparison of averages between the groups using test t Student, (alpha=5%). Results: There enrolled 27 subjects. There were differences in horizontal alignment of head (3.37x1.33), acromia (2.60x1.18), iliac spines (2.91x0.67), vertical alignment of head (25.70x18.26) and in length of lower limbs (1.36x0.75) in respect to cervical and asymptomatic subjects. Conclusions: Was possible identify and quantify the static posture alignment of individuals with and with no cervical pain. The data obtained suggest the presence of asymmetry in all the symptomatic individuals studied. The data obtained suggest the presence of overall asymmetry in all the symptomatic individuals studied. © 2009 Springer-Verlag.

Educative games and expositive lesson: Comparison of educational techniques on sitting posture

Introduction: Studies on education in health are important for the concretion of action of promotion of the health. Objective: To verify the changes of theoretical knowledge on sitting posture, evaluated at two moments (initial and final,) considering two programs of education (expositive lesson and operative groups). Methods: 75 pupils had been citizens, of both the sexes, three 4as series of a public school, evaluated previously (A1) on seated position; group 1 was submitted to a procedure of expositive education, the 2 educative games in the 2 and, the 3 to no intervention. After one week they had been reevaluated (A2). For the moments the test of Wilcoxon was applied and between the Kruskal groups Wallis. Results: In the comparison inside of the groups, of 2 and 3 they had presented increase in the number of rightness on position seated in the after-test, with statistical significant difference, whereas in the group has controlled, such fact did not occur. In the comparison between groups, at the first moment (A1), 2 groups e 3 had not presented significant difference statistical (p > 0,05), however, in as moment notices that it had difference statistics between the three groups (p < 0,01), being that the G3 presented minor frequency of errors (md = 5) in relation to the g2 (md = 8) and g1 (md = 10). Conclusions: It can be affirmed that educative techniques that supply information and promote debates and exchanges of experiences between the participants increase the possibilities of incorporation of the contents related to the sitting posture.

Occupational ergonomics: Work posture among Brazilian dental students

This study involved observational assessment of work posture in relation to recommended ergonomic posture the requirements necessary for ergonomic posture among students in the final year of a degree program at the School of Dentistry of Araraquara-UNESP/Brazil (n =73) and investigation of the association of work posture with sex, the type of procedure, four-handed dentistry, and the region of the mouth being treated. The work posture of the students during 250 clinical procedures was observed by means of pictures. Each procedure received a posture classification: Adequate, partially adequate, or inadequate. A descriptive statistical analysis was conducted. The prevalence of final posture classification was calculated using 95% confidence intervals and point estimate. Associations of interest were studied using the chi-square test, with a 5% significance level. It was concluded that the prevalence of procedures performed with partially adequate posture was high, and that the final work posture classification was not associated with the variables of interest. © 2013 Taylor & Francis Group.
