“…43 Clini cal advice is often provided to avoid or minimize specific sports, wear special backpacks or minimize their use, and adhere to specific exercise and postural correction programs. 1 While some of these labels are clini cally appealing, the evidence underpin ning them is largely limited. Our group has investigated the relationship between a number of these different factors and LBP in adolescents, outlined as follows.…”

“…not severe, with variance influence factors (VIF) ranging between 1.2-1.6 ( Table 4; [80]). Based on standardized beta weights, the engagement (highest), visual comfort, and image quality were more determinative of user satisfaction than negative effects (lowest; see Table 4).…”

“…As median and mean viewing distances observed in homes of 6 H and 6.5 H [43], respectively, viewing distances outside the above recommended ranges appear common in practice. It was reported that the mean preferred viewing distance for visual comfort using HD TVs was 3.8 W (6.8 H) for 32" TVs, 3.6 W (6.5 H) for 37" TVs, and 3.6 W (6.5 H) for 42" TVs [80]. These values are also above the values (6 H https://doi.org/10.1371/journal.pone.0228437.t005…”

Although watching TV often involves multiple viewing distances and viewers, less attention has been paid to the effects of display curvature radius, viewing distance, and lateral viewing position on TV watching experience. This study examined the effects of four display curvature radii (2300R, 4000R, 6000R, and flat), two viewing distances (2.3 m and 4 m), and five lateral viewing positions (P 1-P 5 ; 0, 35, 70, 105, and 140 cm off-center) on seven TV watching experience elements (spatial presence, engagement, ecological validity, negative effects, visual comfort, image quality, and user satisfaction). Fifty-six individuals (14 per display curvature radius) were seated in pairs to watch videos, each time at a different viewing position (2 viewing distances × 5 paired lateral viewing positions). The spatial presence and engagement increased when display curvature radius approached a viewing distance and lateral viewing position approached P 1 , with 4000R-4m-P 1 (display curvature radius-viewing distance-lateral viewing position) providing the best results. Lateral viewing position alone significantly affected five TV watching experience elements; the spatial presence and engagement decreased at P 3-P 5 , and ecological validity, image quality, and user satisfaction decreased at P 4-P 5. However, display curvature radius alone did not appreciably affect TV watching experience, and viewing distance alone significantly affected visual comfort only, with a 4-m viewing distance increasing visual comfort. This study demonstrated that effective display curvature radii for watching TV are viewing distance-dependent, and less off-center lateral viewing positions (P 1-P 2) are recommended for TV watching experience. Finally, among the TV watching experience elements, engagement explained user satisfaction to the greatest degree.

“…It is believed that the excessive burden of the backpack affects the physiological and biomechanical parameters of children, as energy cost or expenditure, posture, fatigue, contact pressure, gait, spinal curvature and compression, and pulmonary capacity [13,14]. Some researchers assume that the use of heavy backpacks is possible contribute to high reports of back pain in children.…”

Objective The objective of this study was to assess school backpacks and associated problems across school going children aged 8–12 years in Lahore, Pakistan. Self-perceived pain related to bag pack use, correlation between self-reported pain and perceived weight of bag pack, duration of bag pack carriage and the method of bag pack carriage were evaluated. Methodology A cross-sectional survey was conducted on 3500 students from different private schools across Lahore. Both male and female students from the age of 8–12 years that were present on the day of the study with no apparent physical deformity or any musculoskeletal disorder were included in the study. Questionnaire used in this study was a modified questionnaire from a previous study.Data collected through questionnaire was coded into SPSS version 18.Data was represented in the form of graphs, tables, cross tabs and bar charts. Chi square test of association was applied with p value<0.05 considered as significant. Results The results indicate that 82% of students surveyed carry bag packs, 54.66% of the students perceived the weight of their bag pack heavy, 40.22% medium while only 5.12% reported their bag pack lightly weighed. Pain was higher in individuals who perceived their bag pack weight heavy (i. e., 48%) pain, who carried their bag pack for over 20 min (44%) pain and over 30 min (56%) pain, respectively. Similarly percentage of pain was higher in individuals who carried their bag pack at one shoulder (i. e., 74%) pain. Conclusion The results of the present study show that there is a relationship between bag pack use, duration and method of bag pack carriage this suggests that heavy, medium and light bag packs may have damaging effects for the school going children. A study to compare children who follow and that do not follow the recommended guidelines should be conducted to find out the guidelines could help reduce back pain, the bag pack guidelines have addressed bag pack weight and duration of carriage should be considered.
