A Visual Scan Analysis Protocol for Postural Assessment at School in Young Students

The effect of exercise on postural alignment: A systematic review

Exercises are indicated for the prevention and treatment of postural disorders, considering the idea of strengthening the weak and lengthened part of the musculature and stretching the short and strong part. However, it is important to know the type and amount of exercise shown to be effective in the improvement of postural dysfunctions. Thus, the objective of this systematic review is to analyze the effect of postural exercises on postural alignment and describe the type and amount of exercise demonstrated to improve postural deviation. For this, a search for articles published in MEDLINE, Sportdiscus, Scielo Web of Science, Science Direct, and Cochrane Central Register of Controlled Trials databases was conducted with the following keywords: exercise, physical activity, fitness, strength training, physical therapy, rehabilitation, Pilates, postural disorder, musculoskeletal dysfunction, and spinal disorder. Twenty-two studies were included in this review and combined into four categories: forward head and shoulder dysfunction; hyperkyphosis; postural alignment; and scoliosis. Different types of exercises, involving strengthening and stretching the musculature and its antagonist, seem to be effective for improving postural dysfunction. The intensity, volume, and duration of the exercise need to be taken into consideration, as well as the practice of specific exercises for the musculature involved in the postural misalignment.

Is There a Relationship between Idiopathic Scoliosis and Body Mass? A Scoping Review

The etiopathogenesis of idiopathic scoliosis remains unknown, although genetic or hereditary factors, neurological disorders, hormonal and metabolic dysfunctions, biomechanical factors, and environmental factors seem to be involved. Several studies have found that patients with scoliosis have common characteristics of taller stature, lower body mass index (BMI), and low systemic bone mass. We conducted a scoping review to analyze the association between idiopathic scoliosis and BMI. The search for articles was performed on PubMed and Cochrane, including the English language, full-text and free-full-text articles published from 31 December 2011 to 31 December 2021. Most of the results analyzed are in favor of a relationship between low BMI and scoliosis. Having a low BMI could be associated with the presence of scoliosis, although the reason for which is still doubtful. However, further large-scale epidemiological studies on different ethnicities and a comparison of BMI with the healthy population will be needed to better define the correlation between BMI and scoliosis.

Risk Factors, Lifestyle and Prevention among Adolescents with Idiopathic Juvenile Scoliosis: A Cross Sectional Study in Eleven First-Grade Secondary Schools of Palermo Province, Italy

Adolescent idiopathic scoliosis (AIS) has an incidence of 2–3% in the general population and a multifactorial etiology. The present study aims to analyze modifiable risk factors and their interactions in the development of AIS in order to increase knowledge about the disease and to prevent the evolution of AIS in young students with tailored public health strategies. A cross-sectional study was conducted over two consecutive school years among students attending 11 first-grade secondary schools in the province of Palermo, Italy. A self-administered questionnaire that investigated socio-demographical, physical and anamnestic characteristics and habits, focusing on possible risk factors associated with idiopathic scoliosis, was administered. In addition, a clinical evaluation was performed with Adams’ test and Bunnel’s inclinometer. Suspected AIS cases were associated with the practice of high-risk sports (p < 0.05), weekly physical activity lasting ≥3 h (p < 0.05), lower back pain (p < 0.001), posture disorders (p < 0.01) and having had no contact with a physician (p < 0.01). Practice of high-risk sports (adj OR = 1.83; CI 95% 1.11–4.76) and suffering of posture disorders (adj OR = 1.67; CI 95% 1.12–3.60) showed a significant association with a confirmed diagnosis of AIS (Cobb angle ≥ 10° at X-ray). The risk factors associated with AIS are still unclear. Therefore, it is crucial to identify early modifiable and multiple risk factors to prevent the evolution of scoliosis in school-age children.

Study of the Association between Postural Misalignments in School Students

Nowadays, postural misalignments prevalence in students is increasingly evident and its early detection is the best way to prevent complications in adulthood. It is also known that postural problems appear to have association between them. The aim of this study was to characterize and study the association between spine, scapular and pelvic girdles postural misalignments in 213 school students (124 males and 89 females), aged between 10 and 20 years, from Escola Básica e Secundária de Santa Maria (EBSSM). To understand the relation between postural misalignments we compare the head positioning with the shoulder girdle, the shoulder girdle with the dorsal spine and the lumbar spine with the pelvic girdle. The postural assessment was made by visual scan analysis in a symmetrograph based on photogrammetry and the Adams. We found high percentages of postural misalignments in all subjects. High prevalence was observed in the posterior view of the frontal plane in the head lateral flexion, shoulders vertical asymmetry, scoliosis and in the presence of gibbosity, whereas, in the right view of the sagittal plane forward head posture and protracted shoulders were observed. The lumbar scoliosis was more prevalent in subjects with iliac crest’s asymmetry (p < 0.001) and forward head posture was significantly related to the subjects with protracted shoulders (p = 0.010). The protracted shoulders were more prevalent in subjects with dorsal hyperkyphosis (p = 0.048) and lumbar hyperlordosis was related to the subjects with pelvic anteversion (p < 0.001). The students’ postural assessment showed a wide variety of postural misalignments. It also seems evident that there is a relationship between their occurrences. It should be highlighted the importance of postural assessment in physical education (PE) classes to determine postural misalignments among school students.
