Biomechanical characteristics of low back tissues during trunk flexion-extension
… and neural regulatory mechanisms of the flexion-relaxation phenomenon (FRP), observed in deep trunk flexion, was performed since it is believed these mechanisms provide insight into the causes of low back injury and pain. Three methods were used to analyze the behavior of the lumbar …

Passive Stiffness Characteristics of the Scoliotic Lumbar Torso in Trunk Flexion, Extension, Lateral bending, and Axial Rotation
… side bending, torso axial rotation, and torso flexion/extension) that isolated mobility to the in vivo lumbar spine. Scoliotic individuals with Cobb angles ranging 15-75 degrees were accepted. Applied torque was measured using a uni-directional load cell, and inertial measurement units (IMU) …

Experimental and Simulation Based Dynamic Assessment of Flexion and Extension Movements of Torso
… cause LBDs. Occupational tasks involving dynamic trunk movements, muscle fatigue, and spinal instability are identified as major risk factors for developing low back pain. Dynamic stability and muscle forces during trunk flexion-extension movements are studied in this dissertation. Torso muscle …

The Physical Implications of Diastasis Recti Abdominis Among Women at the End of Their First Postpartum Year
… is limited evidence to support that DRA impairs trunk muscle function. Four studies are presented in this dissertation, in which we aimed to investigate the impact of DRA on women’s health. The first two studies established the reliability and validity of two key outcome measures. A custom …

LOW BACK DISODERS AMONG WASTE COLLECTION WORKERS: PREVALENCE AND RISK FACTORS
… inertial sensor was also used to measure trunk movement, which included time spent in various movement ranges and velocities. Results Objective 1: Only thirteen full-text articles met the study criteria and underwent data extraction. The majority of articles reported a 12-month prevalence …
