(Pdf) school children’s backpacks, back pain and back pathologies radiografia columna lumbar

Background: Backpack loads of school students during school days have been suggested to range from 10% to as high as 25% of their body weight and may have a negative impact on their body. The aim of this review was to identify and review studies escoliosis lumbar levoconvexa that have examined impacts of contemporary backpack loads on school children. Methods: A systematic search was conducted of the literature using key search terms. After relevant studies published in recent years were selected using strict inclusion and exclusion criteria, the studies were critically appraised and relevant data were extracted and tabulated prior to conducting a critical narrative synthesis of findings. Results: Twenty-one studies were included, ranging in methodological quality from poor to good (critical appraisal scores 22% to 77%).


Students carried on average over 15% of their own body weight, which caused biomechanical and physiological adaptations that could increase musculoskeletal injury risk, fatigue, redness, swelling and discomfort. Conclusion: Considering the limited methodological quality and variations in foci across studies, further research is needed to elucidate: (1) the loads students carry around on a school day in their school backpacks and; (2) the biomechanical, physiological and physical effects of load carriage on students.

Background: School children are at a development age and it is important that they do not carry excessive loads. Heavy school bags can change the body posture and the musculoskeletal system must react appropriately in order to compensate for this stress. There is still no consensus about a guideline for weight of school bags. The objective of the present study was to asses the bag weight in school going children, Compare the bag weight with the whole-body weight of children, Percentage of bag weight to whole body weight at different age groups.Methods: 727 children (413 males and 314 girls) were examined from different schools in Davangere. Descriptive analyses and measures of central tendency were performed on the demographic data to describe the sample escoliosis toracica.Results: Overall 21.7% of children carry a bag which is >25% of their body weight, 46.5% children are carrying a bag >20% of their body weight and 74.7% of children carry a bag of >15% of their body weight. 40.9% children between 8-10 years carry bag of >25% and 39.8% of them between 11 -13 years carry bag of >20% and this is statistically significant (p = 0.000).Conclusions: The weight of schoolbags of school children were higher than the internationally acceptable standards in majority of school children. The school authorities and ministry of health should further evaluate and take the necessary steps to rectify the situation. Early intervention and good regulation can prevent long term complication.

Introduction: Musculoskeletal pain is one of the most important pains among adolescents. Objectives: This study was carried out to determine the prevalence of musculoskeletal disorders and its related complications among students in Ardebil. Patients and Methods: This cross-sectional descriptive study was conducted on 158 students selected by random sampling for participation in a study from two male and female schools in Ardebil. After introducing and explaining the study goals and obtaining informed consent, the Nordic questionnaire was completed by interviewing. Results: of all students participating in the study, 55% had pain in the musculoskeletal system. The most severe pain was reported in the knee zone and the mildest pain in the pelvic zone that overall knee pain was revealed in 29.5% and neck pain in 27.3%. There was a significant relationship between body mass index (BMI) of students and musculoskeletal pain. Additionally, a significant relationship between height and rx de columna lumbar normal musculoskeletal features was seen. There is also a significant relationship between the type of school bag and musculoskeletal disorders. Conclusion: Musculoskeletal discomfort is commonly reported among students in Ardabil city with an overall prevalence of 55%. This discomfort is potentially influenced by students’ body mass index, type, shape and quality of bags.

Low back pain in adolescents is perceived to be uncommon in the clinic setting. However, previous studies have suggested that it may be an important and increasing problem in this age-group. The aim of this study was to determine the prevalence and important symptom characteristics of low back pain such as duration, periodicity, intensity, disability and health seeking behaviour at young ages. A population-based cross-sectional study was conducted including 1446 children aged 11-14 years in the North-West of England. A self-complete questionnaire was used to assess low back pain prevalence, symptom characteristics, associated disability and health seeking behaviour. An additional self-complete questionnaire amongst parents sought to validate pain reporting. The 1-month period prevalence of low back pain was escoliosis derecha 24%. It was higher in girls than boys (29 vs. 19%; 2=14.7, P<0.001) and increased with age in both sexes (P<0.001). Of those reporting low back pain, 94% experienced some disability, with the most common reports being of difficulty carrying school bags. Despite this high rate of disability, few sought medical attention. Adolescent low back pain is common although medical attention is rarely sought. Such symptoms in childhood, particularly as they are so common, may have important consequences for chronic low back pain in adulthood.

Concerns regarding the effects of load carriage have led to recommendations that backpacks be limited to 10?-?15% of body weight, based on significant changes in physical performance. However, gait responses to backpack loads are not entirely consistent and there is a particular lack of data regarding load-bearing gait in adolescent females. Gait patterns of 22 normal adolescent girls were recorded at backpack loads of 0, 7.5, 10.0, 12.5 and 15.0% body weight esclerosis lumbar. Temporal-distance, ground reaction force and joint kinematic, moment and power parameters were analysed by repeated measures ANOVA with factors of backpack load and side (left or right). Walking speed and cadence decreased significantly with increasing backpack load, while double support time increased. Kinematic changes were most marked at the proximal joints, with a decreased pelvic motion but a significant increase in the hip sagittal plane motion. Increased moments and power at the hip, knee and ankle showed increasing demand with backpack load. Parameters showed different responses to increasing load, and those that suggested a critical load indicated this to be approximately 10% body weight. While this may be due to a change in gait due to increased demand, further work is required to verify this and also to examine the cumulative effects of backpack load on the musculoskeletal system, which may be more appropriate in determining recommended load limits.

High prevalence rates of low back pain among children and adolescents have been demonstrated in several studies, and it has been theorized rotoescoliosis lumbar izquierda that low back pain in childhood may have important consequences for future low back pain. It is important to understand the nature of such a link if effective preventive programs are to be established.

Almost 10,000 Danish twins born between 1972 and 1982 were surveyed by means of postal questionnaires in 1994 and again in 2002. The questionnaires dealt with various aspects of general health, including the prevalence of low back pain, classified according to number of days affected (0, 1-7, 8-30, >30).

Low back pain in adolescence was found to be a significant risk factor for low back pain in adulthood with odds ratios as high as four. We also demonstrated a dose-response association: the more days with low back pain at baseline, the higher the risk of future low back pain. Twenty-six percent of those with low back pain for more than 30 days during the baseline year also had more than 30 days with low back pain during the follow-up year. This was true for only 9% of the rest of the sample.

Our study clearly demonstrates correlations between low back pain in childhood/adolescence and low back pain in adulthood. This should lead to a change in focus from the adult to the young population in relation to research, prevention, and treatment.

The school backpack constitutes a daily load for schoolchildren: we set out to analyse the postural effects dolor lumbar derecho rinon of this load, considering trunk rotation, shoulder asymmetry, thoracic kyphosis, lumbar lordosis, and sagittal and frontal decompensation from the plumbline. A group of 43 subjects (mean age = 12.5 +/- 0.5 years) were considered: average backpack loads and average time spent getting to/from home/school (7 min) had been determined in a previous study conducted on this population. Children were evaluated by means of an optoelectronic device in different conditions corresponding to their usual everyday school backpack activities: without load; bearing 12 (week maximum) and 8 (week average) kg symmetrical loads; bearing an 8 kg asymmetrical load; after fatigue due to backpack carrying (a 7-minute treadmill walking session bearing an 8 kg symmetrical load). Both types of load induce changes in posture: the symmetrical one in the sagittal plane, without statistical significant differences between 8 and 12 kg, and the asymmetrical one in all anatomical planes. Usual fatigue accentuates sagittal effects, but recovery of all parameters (except lumbar lordosis) follows removal of the load. The backpack load effect on schoolchildren posture should be more carefully evaluated sintomas de escoliosis lumbar in the future, even if we must bear in mind that laws protect workers to carry heavy loads but not children, and results in the literature support the hypothesis that back pain in youngsters is correlated with back pain in adulthood.

The scientific community acknowledges that the load carried in backpacks by elementary and middle school students is a critical point and a risk factor for the onset of back pain in children and adolescents, and that this symptom can last in the adulthood. There is a discussion about which is the load that represents less risk, 10% versus 15% of body weight. This cross sectional study aimed to … [Show full abstract] evaluate the load carried by students in primary and secondary state schools, in Brazil and quantifies the percentage established between backpack weight and body mass contractura lumbar ejercicios of these young people carry every day. For data analysis were used descriptive statistics methods and inferential statistics methods such as t-Student test, analysis of variance (ANOVA) and Tukey-test for multiple comparisons. A significance level of 0.05 was considered. Participated in this study 916 students of both genders. The age varies from 10 – 19 years old and mean age of 14,12 (± 2,11 SD). 59,06% carrying bag over 10% of body mass, with the load ranging from 10, 02 to 33,43% (average 13,84 ± 3,48 SD). It was observed that younger students, female and those who opted for the backpack model designed dorsal attachment tended to carry a load higher than 10% of his body weight. 24,45% students complain of back pain and shoulder. Data confirm the use of a cutoff of 10% of body weight for the safe use of backpacks for all school levels. It was concluded that the load carried by the study population is inadequate from the point of view of biomechanics and ergonomics, especially for younger individuals and females, since they are in growth phase, and that the overhead exposes them to greater risk of spinal injuries, with consequent repercussions in adulthood.
