- Effectiveness of global postural reeducation in postural changes and postural stability in young adultsPublication . Pacheco, Maria Paula; Morais, Sara; Carvalho, Paulo José; Cavalheiro, Luís; Sousa, Filipa; Carvalho, PauloPostural changes are considered a public health issue and have gathered significant interest in both research and clinical practice. To evaluate the effectiveness of Global Postural Reeducation (GPR) in improving postural changes and postural stability in healthy young adults. Additionally, this study aims to identify the main postural changes in the sample population. A longitudinal study was conducted with a sample of students (n = 38) from the 2nd and 3rd years of undergraduate programs at Coimbra Health School, divided into an experimental group (EG) with 20 subjects and a control group (CG) with 18 subjects. The EG underwent a GPR intervention, while the CG received no intervention. Postural changes were assessed using a 3D motion analysis system (Qualisys), and stabilometry was evaluated using a Bertec force platform. At baseline (T0), the groups were homogeneous regarding sample characterization variables, as well as postural and stabilometric variables (p > 0.05). After four weeks of the intervention (T1), no significant differences were observed between the EG and CG for any of the variables studied (p > 0.05). However, within-group analysis for the experimental group revealed a significant difference (p = 0.04) in anterior-posterior velocity, indicating a reduction in this parameter from T0 to T1. In the control group, a significant difference was observed (p = 0.03) in the left knee valgus, indicating a reduction in valgus alignment. GPR does not appear to be effective in improving postural changes or center of pressure displacement in healthy young students.
- Prevalence of postural changes and musculoskeletal disorders in young adultsPublication . Pacheco, Maria Paula; Carvalho, Paulo; Cavalheiro, Luís; Sousa, Filipa ManuelPostural changes are considered a public health problem, especially those that affect the spine, as they may predispose to degenerative conditions of the spine in adulthood. Musculoskeletal disorders are the main cause of chronic pain, illness, reduced educational performance, productivity, and quality of life, and are responsible for increased absenteeism, which could compromise the future career of students. The purpose of this study was to identify the prevalence of postural changes and the occurrence of musculoskeletal disorders in different anatomical regions in the 12 months prior and 7 days prior to the application of the questionnaire and the number of affected anatomical regions. This is an observational, descriptive, cross-sectional study. It included 508 students selected by a stratified random sample. Our outcomes were the Portuguese version of the Standardized Nordic Musculoskeletal Questionnaire, the Adam’s test, a scoliometer, and the visual analog pain scale associated with the Nordic Musculoskeletal Questionnaire. In total, 79.3% of the students tested positive with the Adam’s test. The neck, shoulder, lumbar region, and knee stood out in all of the temporal references, the 12 months prior (44.3%; 35.2%, 50.2%, 34.1%) and the 7 days prior (16.5%, 16.9%; 28.9%, 17.5%), and even in the restriction of activity due to painful symptoms in the 12 months prior (4.3%, 5.3%, 10.6%, 8.5%). Out of 497 students, 403 were identified with postural changes. The high prevalence rate of identified musculoskeletal symptoms in the anatomical regions of the neck, lumbar region, and shoulder raises the need for intervention in students. Gender appears to generate differences between men and women. Pain from multiple body sites is frequent among young adults.
