Head-Trunk Coordination And Coordination Variability During Anticipated And Unanticipated Sidestepping, Sam Zeff
Masters Theses
INTRODUCTION: Sensory systems within the head provide us with rich perceptual information and may require complex control of the head during locomotion when changing direction. Head position in space is maintained by head on trunk motion as well as lower extremity kinematic modifications, such as increased knee flexion and increased stance time in order to facilitate shock attenuation and reduce vertical CoM displacement. It has been established that the body organizes its degrees of freedom of the trunk, pelvis and lower extremities differently during anticipated and unanticipated sidestepping, which raises the question of how these modifications affect head control during …

Kinematic Analysis Of Trunk Coordination Throughout The Rowing Stroke Sequence, Mcdaragh Rose Minnock
Masters Theses
Rowing at the elite level requires proper sequencing of the rowing stroke so that the rower is able to produce an efficient stroke while protecting oneself from potential injuries. The cyclic motion of the rowing stroke sequence at low loads often results in overuse injuries, specifically in the lower back. Kinematic data of rower’s pelvis-lumbar-thoracic spine were collected using inertial measurement sensors. An incremental step-test was conducted to observe the influence of increasing intensities on the lumbar-pelvis and lumbar-thoracic segments coordination and coordination variability. This study provides a new way of quantifying rowing kinematics using vector coding. The vector coding …
