Objective: Advances in mobile technology have led to the development of smartphones, whose applications present numerous utilities, such as the analysis of human movement based on inertial sensors. The purpose of this review was to investigate validity and reliability of smartphones in assessing the kinematics of the human spine.
Methods: A systematic search was performed on MEDLINE, Embase, Scopus, and LILACS databases, as well as manual searches.
Background: Pain is a public health problem with negative impact on quality of life.
Objective: To analyze the prevalence of musculoskeletal pain and associated occupational factors among Pilates instructors, and to compare their quality of life relative to Brazilian reference values.
Method: A total of 166 Pilates instructors from Rio Grande do Sul, Brazil (consecutive sampling) with degrees in physical education or physical therapy responded the 36-Item Short-Form Health Survey and Work-related Habits Questionnaire.
Objective: The purpose of this review was to identify different kinematic characteristics between the movements of sit-to-stand-to-sit, sit-to-stand, or stand-to-sit of individuals with and without low back pain (LBP).
Methods: A systematic search was conducted on scientific databases. The analyzed kinematic variables were duration of the movement, reproduction of the movement, ranges of motion, velocity, and acceleration.
Background: Studies conducted with prehospital urgent care workers investigated work-related stress and its repercussions on the workers' mental and physical health.
Objective: To identify risk factors for development of work-related cardiovascular (CVD) and musculoskeletal (MSD) diseases among prehospital emergency care workers.
Methods: We conducted a systematic search on databases PubMed, EBSCO, EMBASE and Science Direct.
Objective: To assess the short- and medium-term effects of the posture education program (PEP) for students of elementary school regarding theoretical knowledge and posture during activities of daily living (ADLs).
Methods: The sample consisted of 38 students (aged 8-12 years) in the third grade of elementary school in Porto Alegre, Rio Grande do Sul (Southern Brazil). The children were evaluated in three moments: prior to attending the PEP (pretest); after attending the PEP (post-test); and five months after the conclusion of the PEP, immediately after a learning review of four lessons (five months follow-up).
Purpose: To determine the psychometric properties of the layout for assessing dynamic posture (LADy).
Methods: The study was divided into 2 phases: (1) development of the instrument and (2) determination of validity and reproducibility. The LADy was designed to evaluate the position adopted in 9 dynamic postures.
[Purpose] The aim of this study was to identify whether postural changes are prevalent with advancing age using a photogrammetric method performing one-year follow-up study. [Subjects and Methods] Thirty-eight schoolchildren were evaluated in 2011 and 2012 in this cohort study. The subjects underwent a postural evaluation, which involved palpation of reference anatomic points, placement of reflexive markers over the anatomic points, image acquisition, and point digitalization using the Digital Image-based Postural Assessment evaluation software.
View Article and Find Full Text PDFAim: To evaluate the use of photogrammetry and identify the mathematical procedures applied when evaluating spinal posture.
Methods: A systematic search using keywords was conducted in the PubMed, EMBASE, Scopus, Science and Medicine(®) databases. The following inclusion criteria adopted were: (1) the use of photogrammetry as a method to evaluate spinal posture; (2) evaluations of spinal curvature in the sagittal and/or frontal plane; (3) studies published within the last three decades; and (4) written entirely in English.
Introduction: The early evaluation of the spine in children is desirable because it is at this stage of development that the greatest changes in the body structures occur.
Objective: To determine the test-retest, intra- and inter-rater reliability of the Flexicurve instrument for the evaluation of spinal curvatures in children.
Method: Forty children ranging from 5 to 15 years of age were evaluated by two independent evaluators using the Flexicurve to model the spine.
Objective:: To investigate the association between behavioral risk factors, specifically postural habits, with the presence of structural changes in the spinal column of children and adolescents.
Methods:: 59 students were evaluated through the self-reporting Back Pain and Body Posture Evaluation Instrument and spinal panoramic radiographic examination. Spine curvatures were classified based on Cobb angles, as normal or altered in the saggital plane and as normal or scoliotic in the frontal plane.
Background: The adapted arcometer has been validated for use in adults. However, its suitability for use in children can be questioned given the structural differences present in these populations.
Objective: To verify the concurrent validity, repeatability, and intra- and inter-reproducibility of the adapted arcometer for the measurement of the angles of thoracic kyphosis and lumbar lordosis in children.
