Introduction:The postural deviations associated with the changes in the habits of young people have increased over the last decades. Investigating the subject by way of a self-perception questionnaire allows one to understand the level of awareness the individual has concerning his/her postural habits. Objective: Designing a self-perception evaluation questionnaire about the postural habits of young people and to validate, pre-test, verify the reliability and the internal consistency of this instrument. Methods: The validity of the content was determined by 10 judges. The study involved young people (15 -18 years old) from Florianopolis/Brazil. The questionnaire was pre-tested, applied to 15 youthful who provided qualitative information about it. The reproducibility was analyzed by way of a test-retest with 40 students, in a one-week gap, and was analyzed by interclass correlation coefficient. The internal consistency was analyzed by Cronbach's alpha with 679 students. A 5% significance level was adopted. Results: Concerning to the validation of content, the questionnaire presented a total coefficient of 0.28 and 72% concordance was observed amongst the reviewers. The interclass correlation coefficient (test-retest) indicated acceptable
The objective of this study was to adapt the Brazilian version, and verify the validity, reliability and internal consistency of the Oliveira questionnaire on low back pain in young people. Material and Methods:The questionnaire was translated from European Portuguese into Brazilian Portuguese by means of translation and re-translation. The validity of the contents was determined by experts who analyzed the clarity and pertinence of the questions. Fifteen young people aged 15 to 18 took part in the pre-test step (qualitative analysis), 40 in the test-retest (reliability) and 679 in the evaluation of internal consistency. The intra-class correlation coefficient and Spearman's correlation coefficient were used in the reliability analysis (test-retest), and Cronbach's alpha to determine the internal consistency (stability). Results:In the translation phase the questionnaire was modified and considered suitable, observing similarity and equivalence of the two versions. After being corrected by the experts in the validation of the contents, the instrument was considered suitable and valid, and in the pre-test, the young people suggested some modifications to make the questionnaire more succinct. With respect to reliability, the values for the intra-class correlation coefficient were between 0.512 -acceptable and 1 -excellent and Spearman's correlation coefficient varied between 0.525 and 1, classifying the instrument as reproducible. The internal consistency was considered acceptable with a 0.757 Cronbach's alpha. Discussion: The Oliveira questionnaire was choosen since it has been used in several Portuguese studies; moreover, it addresses the need to raise data regarding low back pain and associated risk factors. Conclusions:The Brazilian version of the Oliveira questionnaire on low back pain in young people showed valid and reliable cultural adaptation, with good reliability and stability.
Purpose: To investigate inter-and intra-observer agreement in the assessment of lumbar vertebral rotational (VR) asymmetry by a motion palpation test. Methods: For this prospective and descriptive test-retest study, 51 asymptomatic participants (40 women, 11 men; mean age 23.3 [SD 5.6] years) were recruited from the community. Each participant was assessed in two sessions by the same three observers, who assessed VR by means of a palpatory test for movement asymmetry. This test is performed by applying posteroanterior pressure in an alternating manner to the left and right transverse processes of a vertebra to determine motion asymmetry in the transverse plane and thus the vertebral position. Observers classified the vertebral position as neutral, rotation to the right, and rotation to the left; they were blinded to which participant was being assessed and to any previous results. Results: Intra-and inter-observer agreement was verified by the kappa coefficient (k) and the weighted kappa coefficient (k w ). Values of k and k w varied from 0.07 (95% CI, À0.10 to 0.245) to 0.37 (95% CI, 0.11-0.63) for intra-observer agreement and from 0.12 (95% CI, À0.06 to 0.29) to 0.30 (95% CI, 0.08-0.52) for inter-observer agreement. Conclusion: The motion palpation test used to assess VR asymmetry has low agreement levels; therefore, its clinical significance for measuring vertebral position is questionable.Key Words: lumbar vertebrae; motion palpation test; reproducibility of results; spine.

BACKGROUND: Young people tend to spend most of their time in activities involving inappropriate positions, which can promote musculoskeletal alterations and disorders. OBJECTIVE: To investigate the prevalence of low back pain (LBP) in young people and analyse its associations with daily postural habits. METHODS: Cross-sectional and retrospective study evaluating 679 Brazilian young people (15 to 18 years old), using questionnaires about LBP and awareness of postural habits. The prevalence values were calculated for the present moment, the last three months and throughout life. The Mann-Whitney U test and the Chi-square test were applied. RESULTS: The prevalence of LBP at the present moment was 27.2%, 57.7% over the last three months and 73.9% throughout life. Boys and girls presented significantly different values, a larger number of girls manifesting pain for the three moments. The associated postural habits were: turning the body, reduction of lumbar lordosis when seated, not placing the feet on the floor, crossing the legs when sitting in the classroom and at home, sitting or lying in an inappropriate position, and distributing the body asymmetrically on the legs when standing. CONCLUSIONS: Young people from 15 to 18 years of age show a high prevalence of low back pain. Inadequate postural habits adopted during everyday activities are associated with this complaint. These findings could contribute to the implementation of prevention and rehabilitation strategies.
Em março de 2020, a Organização Mundial da Saúde (OMS) comunicou ao mundo a pandemia pela proliferação do patógeno SARS-CoV-2 (novo corona vírus) que, ao infectar o ser humano causa a doença COVID-19 (SAÚDE, 2020). Devido ao fácil contágio, várias medidas de combate à pandemia foram divulgadas e implantadas, dentre elas o distanciamento social, a recomendação de fechamento dos estabelecimentos, o isolamento em casa, entre outras. Neste sentido, o curso de Fisioterapia do Centro de Ciências da Saúde e do Esporte (CEFID) da Universidade do Estado de Santa Catarina (UDESC), considerando a sua responsabilidade social e ética com a comunidade e principalmente com os usuários em atendimento, está buscando opções para fornecer aos pacientes, durante este período de excepcionalidade, uma forma alternativa de cuidado.
Introduction: Low back pain is a common musculoskeletal problem and can become chronic, with varying degrees of disability. Objective: Analyze the factors associated with disability in individuals with chronic low back pain (CLBP), treated in primary care. Methods: Cross-sectional study with 82 basic health unit (BHU) users in the municipality of Florianópolis (Brazil) with CLBP. Sociodemographic and clinical variables, health status, lifestyle and treatment were investigated. Self-rated disability was investigated using the Roland Morris questionnaire (≥ 14 points). The χ2 or Fisher’s exact tests were used in inferential analysis for univariate association and the presence of disability. Multivariate association was analyzed by logistical regression, estimating the crude and adjusted odds ratios (OR) and their respective confidence intervals (95%CI). Results: Adults aged 40-59 years had a greater chance of developing disability (OR: 8.17; 95%: 1.21 - 55.0), while professionally active individuals (OR: 0.08; 95%CI: 0.02 - 0.33) who reported engaging in physical activity ≥ 3 times a week (OR: 0.19; IC95%: 0.04 - 0.83) had less chance of the same outcome when compared to the other participants. Conclusion: Factors related to disability were age, employment status and frequency of physical activity. Incentive strategies to return to work and engage in regular physical activity and exercise should be encouraged.
BackgroundSeveral posture evaluation devices have been used to detect deviations of the vertebral column. However it has been observed that the instruments present measurement errors related to the equipment, environment or measurement protocol. This study aimed to build, validate, analyze the reliability and describe a measurement protocol for the use of the Posture Evaluation Rotating Platform System (SPGAP, Brazilian abbreviation).MethodsThe posture evaluation system comprises a Posture Evaluation Rotating Platform, video camera, calibration support and measurement software. Two pilot studies were carried out with 102 elderly individuals (average age 69 years old, SD = ±7.3) to establish a protocol for SPGAP, controlling the measurement errors related to the environment, equipment and the person under evaluation. Content validation was completed with input from judges with expertise in posture measurement. The variation coefficient method was used to validate the measurement by the instrument of an object with known dimensions. Finally, reliability was established using repeated measurements of the known object.ResultsExpert content judges gave the system excellent ratings for content validity (mean 9.4 out of 10; SD 1.13). The measurement of an object with known dimensions indicated excellent validity (all measurement errors <1 %) and test-retest reliability. A total of 26 images were needed to stabilize the system. Participants in the pilot studies indicated that they felt comfortable throughout the assessment. The use of only one image can offer measurements that underestimate or overestimate the reality. To verify the images of objects with known dimensions the values for the width and height were, respectively, CV 0.88 (width) and 2.33 (height), SD 0.22 (width) and 0.35 (height), minimum and maximum values 24.83–25.2 (width) and 14.56 – 15.75 (height). In the analysis of different images (similar) of an individual, greater discrepancies were observed in the values found. The cervical index, for example, presented minimum and maximum values of 15.38 and 37.5, a coefficient of variation of 0.29 and a standard deviation of 6.78.ConclusionsThe SPGAP was shown to be a valid and reliable instrument for the quantitative analysis of body posture with applicability and clinical use, since it managed to reduce several measurement errors, amongst which parallax distortion.
