Posture

La présente étude analyse les motifs et les enjeux de la toxicographie (écriture intoxiquée) dans Un roman français de Frédéric Beigbeder, écrivain cocaïnomane. L’étude s’ancre dans l’air du temps caractérisé par le consumérisme, l’hédonisme, l’individualisme et l’autobiographisme. Nous essayons de montrer comment Frédéric Beigbeder parvient à justifier son/l’addiction à la cocaïne dans la société occidentale postmoderne. Il élargit l’horizon de sa réflexion socio-philosophique en matière de drogues illicites, aux fins de faire l’apologie de l’hédonisme et des addictions toxiques, en général. Ainsi, à partir d’une approche à la fois textuelle et extratextuelle, l’article soutient l’idée selon laquelle Frédéric Beigbeder est un écrivain toxico-hédoniste libéral et Un roman français constitue une expression toxicographique apolégétique. De loin, ce roman est une illustration éloquente de ce que nous proposons d’appeler, à la suite de Philippe Lejeune, l’autotoxicobiographie, entendue comme l’écriture de soi d’un toxicomane, qui met en évidence le récit de ses addictions toxiques, le sens de sa personnalité et sa philosophie de la vie.

Background: Excessive anterior pelvic tilt (APT) is a common condition that can lead to musculoskeletal problems in females. Pilates and TRX exercises have been suggested as potential interventions to address APT. Aim: The present study aimed to investigate the effect of these exercises on the pelvic tilt angle (PTA) in females with excessive APT. Materials and Methods: The current study utilized a pre-test post-test design and was conducted as a quasi-experimental study. Twenty females between the ages of 35 and 55 were purposefully selected to participate in the study. The pelvic tilt angle (PTA) was measured using an inclinometer. The study participants were randomly assigned to the two groups. Then 8-week TRX and Pilates exercises were carried out. The data was analyzed by paired-sample t-test and analysis of covariance (ANCOVA) at a significance level of P <0.05 using SPSS V. 16. Results: The results showed a significant decrease in PTA in both Pilates (t(9)= 16.74, P = 0.001) and TRX (t(9)= 9.73, P = 0.001) exercises groups. But, there was no a significant difference between the two groups (F(1, 17)=0.01, P = 0.922, partial eta squared= 0.001). Conclusion: The results of the study demonstrated a significant decrease in the pelvic tilt angle (PTA) of participants with excessive anterior pelvic tilt (APT) following 8 weeks of Pilates and TRX exercises. These findings highlight the importance of these exercise interventions in correcting postural deformities.

Background: Hyper kyphosis is a common postural issue that affects many women, often leading to negative body image. Aim: The purpose of this research was to investigate the impact of an 8-week corrective exercise program on the body image of women with hyper kyphosis. Materials and Methods: The research method used in this study was quasi-experimental. The study population consisted of female students aged 18 to 26 years with hyper kyphosis at Shahid Rajaee University. Participants were randomly assigned to either the experimental group (n=20) or the control group (n=20). Hyper kyphosis was measured using a flexible ruler, while body image was assessed using the Body-esteem Scale for Adolescents and Adults. The questionnaire had a reliability coefficient of 0.83 as measured by Cronbach's alpha. After 8 weeks of corrective exercise, both the experimental and control groups completed the questionnaire again. The control group did not receive any training during this time. The data were analyzed using the mixed ANOVA method with SPSS-26 software at a significance level of 95%. Results: The results of the mixed ANOVA analysis showed that the main effect of the training group and the interaction between the group and test stages were significant in the post-test stage for the dependent variable of total body image (F=6.82, P =0.013), appearance (F=6.72, P =0.014), attitude (F=8.81, P =0.005), and kyphosis angle (F=18.91, P =0.000). However, there was no significant effect of training on weight satisfaction. Conclusion: The results of this study indicate that eight weeks of corrective exercise significantly reduced the hyper kyphosis angle ( P =0.01), resulting in an improvement in the subjects' posture and a decrease in deformity. This improvement in appearance led to an increase in satisfaction with their appearance, as demonstrated by improvements in their body image.

Background : Work-related musculoskeletal disorder is the most important occupational disease that threatens the health of employees. Aim: The aim of this study was to investigate the relationship between workers' posture and musculoskeletal disorders. Materials and Methods: Eighty-two male and female workers working in a home appliance factory participated in this cross-sectional study. Musculoskeletal disorders were investigated using Nordic questionnaires. Posture evaluation was performed to measure the angles of forward head, rounded shoulders, and thoracic kyphosis using photogrammetry. Craniovertebral, shoulder, and thoracic kyphosis angles were photographed during the work and then measured using ImageJ software. Data analysis was done using SPSS 26 and Spearman's correlation test at a significance level of 0.05. Results : A significant relationship between the craniovertebral angle and musculoskeletal disorders in the last twelve months was observed in the cervical region ( P <0.001). Also, a significant relationship was observed between the kyphosis angle and musculoskeletal disorders in the last twelve months in the upper back and lower back ( P <0.001). Conclusion : The results showed that the workers’ posture during work is correlated with the prevalence of musculoskeletal disorders. Therefore, it is suggested to pay attention to ergonomic principles during work to maintain and improve the physical health of workers.
