Effectiveness of a Back School and Postural Education Program on the improvement of literacy about postures and low back pain in adolescents: A 1-year follow-up study

Cultural appropriateness of interventions to prevent and reduce musculoskeletal disorders among students: a systematic review

This systematic review was conducted to identify the types of interventions and cultural appropriateness of intervention studies for preventing and reducing musculoskeletal disorders (MSDs) in students. In this systematic review, articles were retrieved from scientific databases including PubMed, Sciencedirect, Web of Science, Scopus, SAGE journals, and Cochrane library using a search strategy. The types of interventions for preventing and reducing MSDs among students published in English up to 2022 were examined, with a comparison of studies in terms of the cultural appropriateness of strategies. Also, studies were categorised based on six intervention types: physical exercise, education, ergonomics, participatory ergonomics, stress management, and multicomponent. Out of the 29 studies included in this review, ten were randomised controlled trials, fifteen were controlled pre-test/post-test studies, and four were pre-test/post-test studies. The articles measured students' knowledge, beliefs, behaviour, good posture/performance, pain intensity decrease, and back care as outcomes. Only two articles were categorised as having moderate cultural adaptation. The results showed that any type of intervention was successful, and two studies were evaluated as having high quality. Our review found evidence of efficacy for interventions aimed at preventing and reducing MSDs in students.

Practitioner summary: Musculoskeletal disorders are common problems that affect students of all ages. To prevent these problems from getting worse or affecting students' future health, it is important to find effective ways to prevent and reduce musculoskeletal disorders in students.

The burden of low back pain in children and adolescents with overweight and obesity: from pathophysiology to prevention and treatment strategies

Nonspecific low back pain (LBP) is one of the most common causes of disability, affecting all individuals at least once in their lifetime. Such a condition is also becoming increasingly frequent in the pediatric population, especially in children and adolescents with overweight/obesity. Furthermore, new-onset LBP during adolescence has been demonstrated to be a strong predictor of developing LBP later in life, contributing to poorer outcomes and increasing social and medical costs. Several causes and different mechanisms have been considered for the development of LBP in pediatric individuals affected by obesity. For this reason, planning adequate prevention and treatment strategies, mainly through conservative lifestyle changes, would be crucial to anticipate the negative consequences of persisting LBP in adulthood. The aim of this narrative review was to characterize the relationship between LBP and overweight/obesity in the pediatric population, highlighting epidemiological and pathophysiological aspects. In addition, prevention and treatment approaches will be reviewed considering the need to reduce the burden of LBP on this population. According to our search, LBP was more frequent in children and adolescents with overweight and obesity and has been associated with several anthropometric and lifestyle factors, including lumbar hyperlordosis, sedentary habits, physical inactivity, carrying a heavy schoolbag, low vitamin D levels, psychosocial ill-being, and premature intervertebral disc degeneration. Most of these conditions may be addressed with conservative strategies mainly consisting of dietary adjustments, physical exercise, education programs, and physical therapy.

Health literacy and musculoskeletal disorders in adolescents: a scoping review

OBJECTIVES

Health literacy (HL) related to musculoskeletal disorders (MSDs) in adolescents is a field with limited previous evidence. This study aimed to review and synthesise studies on MSDs and HL as well as various dimensions of HL in adolescents.

DESIGN

Scoping review in accordance with Arksey and O'Malleys framework and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews.

SEARCH STRATEGY

The search strategy was performed in the following databases in November 2021 (initial search) and December 2022 (updated search); Medline, EMBASE, PsychINFO, Cochrane, CINAHL, ERIC, Web of Science and Google Scholar. Eligible studies involving MSDs and HL or either of the HL dimensions related to finding, understanding, appraising or applying health information in adolescents were considered. Any dimension of HL studied, the outcome measure(s) used to assess HL and the type of MSD examined were charted, reviewed and synthesised. A directed content analysis was used for the subjective interpretation of text data.

RESULTS

A total of 16 841 studies were identified and 33 were eligible for inclusion. Ten articles presented HL with a definition or description in the theoretical background. The remaining 23 studies involved finding, understanding, appraising or applying health information, without using the term 'health literacy'. Most of the studies addressed how adolescents understand (n=32), and apply (n=23) health information, while few studies focused on how they find (n=11) and appraise (n=7) musculoskeletal health information.

CONCLUSION

Few studies have addressed HL and MSDs in adolescents explicitly, while most studies have considered dimensions of HL. Our findings suggest that there is important work to be done to align conceptual understandings with the measurement of HL in adolescents and that further research should be carried out to explore how HL is distributed among adolescents with MSDs and how adolescents living with MSDs report their HL.

Does m-health-based exercise (guidance plus education) improve efficacy in patients with chronic low-back pain? A preliminary report on the intervention's significance

BACKGROUND

The utilization of mobile health (m-health) has rapidly expanded during the COVID-19 pandemic, and there is still a lack of relevant clinical data pertaining to chronic low-back pain (CLBP) management. This study was designed to compare the effectiveness of m-health-based exercise (via guidance plus education) versus exercise (via guidance) during CLBP management.

METHODS

Participants (n = 40) were randomly assigned to intervention and control groups. The intervention group received m-health-based exercise (via guidance plus education), whereas the control group received m-health-based exercise (via guidance). The exercise prescription video and educational content were sent to participants by the application (app), Ding Talk. Repeated-measures analysis of variance was used to test the baseline's intervention effects, 6-week follow-up, and 18-week follow-up. We selected function (Roland and Morris Disability Questionnaire) and pain intensity (current, mean, and most severe Numeric Rating Scale in the last 2 weeks) as the primary outcomes, changes of negative emotion (depression, anxious), and quality of life as the secondary outcomes.

RESULTS

Time's significant effect was found in pain, function, and health-related quality of life in both groups, but time did not show significant interaction effects. Participants were able to use m-based education with their anxiety and depression after treatment, but the relief only lasted until week 6. No differences were found on the aspect of mental health-related quality of life.

CONCLUSION

Preliminary findings suggest that m-health-based exercise (via guidance) may be a convenient and effective method to treat CLBP. However, additional health education didn't help more. More rigorous controlled trials are needed to improve the therapeutic effect in future studies.

Knowledge and Practices of Back Care, Experience in Colombian Children

Early back care has become the preventive strategy to mitigate bad postural habits and musculoskeletal alterations that trigger inadequate postural patterns in the body schema. The objective was to determine the knowledge and practice of back care in first-grade school children after applying an educational intervention for back care. Quasi-experimental study with pre-test and post-tests in a sample of 71 first grade school students. Knowledge and practices for back care were evaluated before and after of the intervention. During 5 weeks, a program of education for back care was developed in the intervention group, formed by concepts about anatomy, physiology, alterations of the spine, adoption of appropriate postures and movements in school life and the execution of adequate movements learned. Simultaneously, physical exercises based on aerobic work, strengthening and stretching the back muscles were carried out with the children in the control group. A linear regression model and a two-level hierarchical model were applied to estimate the effect of the intervention. After the execution of the back care education program, a better score was found in the knowledge and practice questionnaire, which was different between the intervention group and the control group (1.72 95% CI 1.21-2.24). The development of an education program generated a change in the score of the questionnaire on knowledge of back care in the intervnetion group, which suggests the implementation of these strategies in the school context during early childhood, contributing to the prevention of back disorders and deficiencies.
