The primary objective of this research is to model the biomechanical control system employed by the Central Nervous System (CNS) to maintain posture and balance of the HAT (Head-Arms-Torso) during gait. More specifically, the intent is to stabilize a model of the upper body (HAT) so that the HAT response is similar to that found experimentally in human subjects during gait. This will be accompl...

The ramifications of patient migration toward the foot of the bed in intensive care units are not well understood. Migration may cause shear and friction between the patient and the mattress, reduce elevation of the patient's torso, and require frequent repositioning of the patient. This study assesses how bed design impacts both the amount of migration that patients undergo during head section...

Introduction The objective of this study was to report full-torso surface topography (ST) parameters and to determine test-retest standard error of measurement (SEM) in adolescents without spinal deformities. ST is used to quantify the external deformity of the torso due to scoliosis. A normative ST database is being developed to help interpret the ST parameters used to describe scoliosis. Test...

According to the difficulty of marker based motion reconstruction of human torso movements a reduced kinematic formulation of the human spine is introduced, which describes the movement of the first thoracic vertebra in relation to the pelvis. The formulation is for implementation in a multibody model of the human body. As a result the formulation offers convenience in marker based motion captu...

INTRODUCTION Lung counting has many sources of uncertainty that can impact on the activity estimate such as different deposition patterns of radioactivity in the lung, rib size and placement, chest wall composition and profile, effect of detector size and thickness. For example, if a lung counter is calibrated using a lung set that has the activity homogeneously distributed throughout the tissu...

Introduction Surface topography (ST) has been proposed to monitor changes in spinal and rib cage deformity in adolescent with idiopathic scoliosis. The changes in ST parameters used to monitor scoliosis should be related to scoliosis progression and not to changes in torso shape occurring with growth. The objective was to determine the correlation between growth indicators and full-torso surfac...

OBJECTIVES There has been growing controversy regarding long term effects of repeated low severity head impacts such as when heading a football. However, there are few scientific data substantiating these concerns in terms of the biomechanical head response to impact. The present study aimed to develop a research methodology to investigate the biomechanical response of human subjects during int...
