Body posture and physical activity in children diagnosed with asthma and allergies symptoms: A report from randomized observational studies

Comparison between rasterstereographic scan and orthopedic examination for posture assessment: an observational study

Background

Although the relationship between posture and back pain is still under debate, the potential role of body alignment highlights the importance of postural assessment in the health sector. Despite growing concern about musculoskeletal issues, there remains a lack of consensus on effective methods for detecting postural anomalies.

Methods

This observational study compared postural assessments conducted by orthopedic specialists with those obtained through rasterstereographical spine scans using the DIERS formetric system. Fifty-four children from the third grade (mean age 9.4 years) underwent both assessments, allowing for a comprehensive examination of orthopedic abnormalities. Statistical analysis, including McNemar tests, was employed to compare the results of the assessments and evaluate potential discrepancies.

Results

The comparison between the orthopedic examination and the DIERS scan revealed significant differences in assessing trunk imbalance (p < 0.001), thoracic kyphosis (p < 0.001), and lumbar lordosis (p < 0.001). Additionally, the study identified a high prevalence of orthopedic abnormalities, with 79.6% of the examined children exhibiting at least one issue in the orthopedic visual assessment.

Conclusions

The study highlights the divergence between orthopedic evaluations and DIERS scans, emphasizing the challenges in achieving consistent postural assessments. The static analysis provided by the DIERS system, which quantifies posture in angles and distances, contrasts with the dynamic, functionality-focused approach of orthopedic examinations. The findings raise questions about the practicality and significance of integrating rasterstereography into routine pediatric orthopedic practice. The results underscore the complexity of postural evaluations and advocate for a comprehensive approach to address the multifaceted nature of back health in children.

The effect of stretching exercises on the mobility of the spine in the sagittal plane in people using digital devices – preliminary observations

Introduction. Digital devices and a sedentary lifestyle pose significant health risks in today’s society, further exacerbated by the regular adoption of incorrect posture. Prolonged adoption of an incorrect posture can result in pain and impaired spinal mobility. Aim of the study. The study aims to evaluate the impact of stretching exercises on improving cervical, thoracic and lumbar spine mobility in the sagittal plane. Furthermore, it sought to examine the potential correlation between the occurrence of pain and the duration of digital equipment usage. Study materials and methodology. The study was conducted on a sample group of 22 individuals aged 18 to 21 (20.11 ± 1.56) years. Linear measurements, including the Schober and Otto-Wurm tests, were used to examine spinal mobility in the sagittal plane. The subjects were given a 10-day programme comprising six stretching exercises to perform autonomously daily. After ten days, line measurements were retaken. Results. Significant statistical values were observed for spinal ranges of motion in the sagittal plane; no statistically significant value was obtained for the incidence of pain and the duration of use of digital devices. Conclusions. The subjects demonstrated improvement in cervical, thoracic, and lumbar spine mobility in the sagittal plane following the implementation of stretching exercises. Additionally, a decrease in spinal pain was observed.

Physical exercise in asthma adolescents: a concept review

Background: Asthma is a frequent pathological condition during childhood and adolescence. Young asthmatics demonstrate decreased aptitude for physical activity and a limited exercise capacity. Lower hospitalisation rates, reduced school absenteeism, fewer medical examinations, and limited use of bronchodilators have been documented in children and adolescents with bronchial asthma who engage in physical exercise regularly. Structured physical exercise protocols should be encouraged as they can work as a synergistic therapeutic option in addition to regular pharmacologic treatment. This article outlines the most suitable exercise training techniques for young patients with bronchial asthma and their effects on health status.

Posture of Adolescent and the Relationship with Body Mass Index, Sex, and Physical Activity

Background: The increase in overweight and the physical inactivity in children and adolescents in the last years have been causing constant concerns. The comprehension of the postural patterns contributes to the prevention of postural deviations that could predispose to future pain and disabilities. The aim of this study was to assess the association between posture, sex, body mass index (BMI), and physical activity to understand the relationship of these factors with the posture of adolescents. Methods: We evaluated 217 adolescents of both sexes between 11 and 15 years of age who were students in municipal schools in São Paulo. The posture was assessed by photogrammetry, Foot Posture Index, Flexicurve, and the Scoliometer^®. Physical activity was evaluated by the Physical Activity Questionnaire for Children and Adolescent. Results: The group of adolescents with obesity presented a higher angle of lumbar lordosis and the overweight group showed greater anteriorization of the head when compared with the group with normal weight. The females presented greater head anteriorization, Q angle and lumbar lordosis, and the males presented greater projection of the trunk and body forward. The group with sedentary habits showed greater abduction of the scapulae. Conclusions: We concluded that BMI and sex had the highest relationship with the posture of adolescents. Further studies are needed to clarify the association between physical activity and posture. Our results may assist future studies and support preventive and therapeutic actions in the treatment of adolescents' postural changes.

Positioning for acute respiratory distress in hospitalised infants and children

BACKGROUND

Acute respiratory distress syndrome (ARDS) is a significant cause of hospitalisation and death in young children. Positioning and mechanical ventilation have been regularly used to reduce respiratory distress and improve oxygenation in hospitalised patients. Due to the association of prone positioning (lying on the abdomen) with sudden infant death syndrome (SIDS) within the first six months, it is recommended that young infants be placed on their back (supine). However, prone positioning may be a non-invasive way of increasing oxygenation in individuals with acute respiratory distress, and offers a more significant survival advantage in those who are mechanically ventilated. There are substantial differences in respiratory mechanics between adults and infants. While the respiratory tract undergoes significant development within the first two years of life, differences in airway physiology between adults and children become less prominent by six to eight years old. However, there is a reduced risk of SIDS during artificial ventilation in hospitalised infants. Thus, an updated review focusing on positioning for infants and young children with ARDS is warranted. This is an update of a review published in 2005, 2009, and 2012.

OBJECTIVES

To compare the effects of different body positions in hospitalised infants and children with acute respiratory distress syndrome aged between four weeks and 16 years.

SEARCH METHODS

We searched CENTRAL, which contains the Acute Respiratory Infections Group's Specialised Register, MEDLINE, Embase, and CINAHL from January 2004 to July 2021.

SELECTION CRITERIA

Randomised controlled trials (RCTs) or quasi-RCTs comparing two or more positions for the management of infants and children hospitalised with ARDS.

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted data from each study. We resolved differences by consensus, or referred to a third contributor to arbitrate. We analysed bivariate outcomes using an odds ratio (OR) and 95% confidence interval (CI). We analysed continuous outcomes using a mean difference (MD) and 95% CI. We used a fixed-effect model, unless heterogeneity was significant (I² statistic > 50%), when we used a random-effects model.

MAIN RESULTS

We included six trials: four cross-over trials, and two parallel randomised trials, with 198 participants aged between 4 weeks and 16 years, all but 15 of whom were mechanically ventilated. Four trials compared prone to supine positions. One trial compared the prone position to good-lung dependent (where the person lies on the side of the healthy lung, e.g. if the right lung was healthy, they were made to lie on the right side), and independent (or non-good-lung independent, where the person lies on the opposite side to the healthy lung, e.g. if the right lung was healthy, they were made to lie on the left side) position. One trial compared good-lung independent to good-lung dependent positions. When the prone (with ventilators) and supine positions were compared, there was no information on episodes of apnoea or mortality due to respiratory events. There was no conclusive result in oxygen saturation (SaO_2; MD 0.40 mmHg, 95% CI -1.22 to 2.66; 1 trial, 30 participants; very low certainty evidence); blood gases, PCO₂ (MD 3.0 mmHg, 95% CI -1.93 to 7.93; 1 trial, 99 participants; low certainty evidence), or PO₂ (MD 2 mmHg, 95% CI -5.29 to 9.29; 1 trial, 99 participants; low certainty evidence); or lung function (PaO₂/FiO₂ ratio; MD 28.16 mmHg, 95% CI -9.92 to 66.24; 2 trials, 121 participants; very low certainty evidence). However, there was an improvement in oxygenation index (FiO₂% X M_PAW/ PaO₂) with prone positioning in both the parallel trials (MD -2.42, 95% CI -3.60 to -1.25; 2 trials, 121 participants; very low certainty evidence), and the cross-over study (MD -8.13, 95% CI -15.01 to -1.25; 1 study, 20 participants). Derived indices of respiratory mechanics, such as tidal volume, respiratory rate, and positive end-expiratory pressure (PEEP) were reported. There was an apparent decrease in tidal volume between prone and supine groups in a parallel study (MD -0.60, 95% CI -1.05 to -0.15; 1 study, 84 participants; very low certainty evidence). When prone and supine positions were compared in a cross-over study, there were no conclusive results in respiratory compliance (MD 0.07, 95% CI -0.10 to 0.24; 1 study, 10 participants); changes in PEEP (MD -0.70 cm H₂O, 95% CI -2.72 to 1.32; 1 study, 10 participants); or resistance (MD -0.00, 95% CI -0.05 to 0.04; 1 study, 10 participants). One study reported adverse events. There were no conclusive results for potential harm between groups in extubation (OR 0.57, 95% CI 0.13 to 2.54; 1 trial, 102 participants; very low certainty evidence); obstructions of the endotracheal tube (OR 5.20, 95% CI 0.24 to 111.09; 1 trial, 102 participants; very low certainty evidence); pressure ulcers (OR 1.00, 95% CI 0.41 to 2.44; 1 trial, 102 participants; very low certainty evidence); and hypercapnia (high levels of arterial carbon dioxide; OR 3.06, 95% CI 0.12 to 76.88; 1 trial, 102 participants; very low certainty evidence). One study (50 participants) compared supine positions to good-lung dependent and independent positions. There was no conclusive evidence that PaO₂ was different between supine and good-lung dependent positioning (MD 3.44 mm Hg, 95% CI -23.12 to 30.00; 1 trial, 25 participants; very low certainty evidence). There was also no conclusive evidence for supine position and good-lung independent positioning (MD -2.78 mmHg, 95% CI -28.84, 23.28; 25 participants; very low certainty evidence); or between good-lung dependent and independent positioning (MD 6.22, 95% CI -21.25 to 33.69; 1 trial, 25 participants; very low certainty evidence). As most trials did not describe how possible biases were addressed, the potential for bias in these findings is unclear.

AUTHORS' CONCLUSIONS

Although included studies suggest that prone positioning may offer some advantage, there was little evidence to make definitive recommendations. There appears to be low certainty evidence that positioning improves oxygenation in mechanically ventilated children with ARDS. Due to the increased risk of SIDS with prone positioning and lung injury with artificial ventilation, it is recommended that hospitalised infants and children should only be placed in this position while under continuous cardiorespiratory monitoring.

Effect of Eutonia, Holistic Gymnastics, and Pilates on body posture for pre-adolescent girls: Randomized clinical trial

INTRODUCTION

Postural changes frequently occur in pre-adolescent girls, with sedentary lifestyle with reduced physical activity level as one of the risk factors.

OBJECTIVE

To investigate the effects of Eutonia, Holistic Gymnastics, and Pilates on body posture in pre-adolescent girls.

METHODS

A randomized prospective quantitative clinical trial was conducted. The study included girls aged 10-13 years and compared the effects of Eutonia, Holistic Gymnastics, and Pilates on body posture. The sample comprised 80 girls divided into three intervention groups as follows: Eutonia group, 26 girls; Holistic Gymnastics group, 27 girls; and Pilates group, 27 girls. Ten sessions of 1 h each were conducted on a weekly basis. Static posture was analyzed using the Postural Analysis Software SAPO; dynamic posture, using the modified Layout for Assessing Dynamic Posture LADy; and lifestyle, using the Body Posture Evaluation Instrument Back PEI questionnaire. The data were statistically analyzed using the analysis of variance (ANOVA) by Kruskal-Wallis' averages test at 5% significance level (p < 0,05).

RESULTS

The results showed that the three body movement practices improved the head inclination in the frontal plane (1,49°) and pelvic anteversion in the right (1,9°) and left profiles (2,09°). In addition, 25% of pre-teens started to carry their school bag correctly, improving their posture.

CONCLUSION

The body movement practices of Eutonia, Holistic Gymnastics, and Pilates improved head inclination, pelvic anteversion, and the correctness rate of carrying the schoolbag.

Impact of Asthma on Plantar Pressures in a Sample of Adult Patients: A Case-Control Study

Based on the high prevalence of asthma in the population, and its relationship with various musculoskeletal and postural disorders, the aim of this study was to evaluate the plantar pressures in asthmatic patients compared to a control group. A case-control study involving 90 participants was conducted, consisting of 45 asthma patients and 45 healthy paired controls. Static plantar pressure data were recorded using a portable pressure sensor platform. Statistically significant differences were shown in the body weight on the left heel (p = 0.031), and the right forefoot maximum peak pressure was lower in the case group (p = 0.042). The findings of this study show alterations in static plantar pressures in asthmatic patients compared to healthy individuals. Specifically, the subjects with asthma showed less maximum pressure in the right forefoot and less weight on the left heel, which appear to be associated with the asthma disease.

Effects of lumbar lordosis increment on gait deteriorations in ambulant boys with Duchenne Muscular Dystrophy: A cross-sectional study

BACKGROUND

Increment of lumbar lordosis, a frequent spinal finding in Duchenne Muscular Dystrophy (DMD), is a compensatory mechanism secondary to muscle weakness. However, excessive lumbar lordosis may change the position of the center of mass, and lead to balance and walking difficulties.

OBJECTIVE

To study the relationship between factors that may influence ambulatory function in boys with DMD and to investigate the effects of lumbar lordosis increment on gait and balance perturbations.

METHODS

Twenty-one ambulant patients with DMD and 10 healthy boys were included. Lumbar lordosis and thoracic kyphosis angles, dynamic and static balance tests, ambulatory function, muscle strength, and disease severity were assessed. Usage of steroids and orthotic devices were recorded. Scoliosis was assessed on radiographs. Receiver operator characteristic curves were formed and area under curve (AUC) measurements were performed to assess the ability of the tests to discriminate ambulatory status and optimal cut-off values were established according to the Youden index.

RESULTS

The amount of lumbar lordosis correlated strongly and negatively with quality of ambulation (r = -0.710) and moderately with performance on balance tests. The strength of both upper limbs and lower limbs muscles were not associated with any of the variables. According to the AUC analysis, patients with a lumbar lordosis higher than 36° had worse scores on gait and dynamic balance tests.

CONCLUSION

Ambulation and dynamic balance are negatively affected by the increment of lumbar lordosis with a cut-off point of 36°in boys with DMD.

Evaluating the validity of diagnostic methods for scoliotic posture of primary school children

Primary school children are exposed to asymmetric loads that lead to an imbalance of postural muscles and a violation of the body relative symmetry. Mass screening examinations in schools for scoliotic posture and scoliosis are conducted primarily through the Adams test. It has low reproducibility and a high frequency of false negative results. In practice, various methods for diagnosing posture disorders are also used. Some methods are based on the evaluation of postural muscles static endurance, elasticity and proportionality of their functional capabilities. Others are based on a comprehensive assessment of the ability to maintain an upright posture rationally. The third ones are based on the analysis of the tonic vibration and H-reflex of skeletal muscles on both sides of the vertebral column. All the above mentioned methods definitely have diagnostic potential. Therefore it was decided to determine the validity of some common methods for diagnosing posture disorders based on the analysis of their mutual congruence. Based on the results of the experiment, a reliable correlation between the studied parameters was established. It in turn allows us to judge the congruence of the considered diagnostic methods and, accordingly, the high probability of their validity.
