The influence of physical exercise on behavioral habits, kinesiophobia, and disability in people with low back pain: A retrospective cross-sectional study.

Introduction: Physical exercise improves physical fitness and health, helping to reduce pain and prevent low back pain. This study aims to compare the intensity of low back pain (LBP), behavioral habits, and the level of disability and kinesiophobia among exercising and non-exercising subjects with LBP.

Methods: Consecutive sample of 102 individuals was divided into exercising group (EG) and non-exercising group (NEG).

Validity and Reliability of Smartphones in Assessing Spinal Kinematics: A Systematic Review and Meta-analysis.

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.

Validation of the Measurement of the Angle of Trunk Rotation in Photogrammetry.

Objective: The purpose of this study was to validate the photogrammetric measurement of the angle of trunk rotation in relation to the scoliometer instrument.

Methods: Fifty-eight prominences from individuals with ages between 7 and 18 and with suspicion of spinal asymmetry (SA) were evaluated through the scoliometer and photogrammetry. The photographs were analyzed in the Digital Image-based Postural Assessment software.

Kinematic Characteristics of Sit-to-Stand Movements in Patients With Low Back Pain: A Systematic Review.

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.

Repeatability and Reproducibility of Postural Variables by Photogrammetry.

Objective: This study aimed to examine the reliability of postural variables analyzed by photogrammetry obtained at different instances on the same day and between 2 different days.

Methods: A sample composed of 24 healthy adult individuals of both sexes was submitted to photogrammetric postural assessment. From 35 seconds of filming, 7 photographs (of time instance at 0 second, 05 seconds, 10 seconds, 15 seconds, 20 seconds, 25 seconds, and 30 seconds) were extracted and digitalized on digital image-based postural assessment software.
