The aim of this study was to compare the spine-pelvis coordination and variability (CV) during rowing in elite rowers with without chronic low back pain (CLBP). Fourteen professional (6 healthy 8 CLBP) participated study. 3D kinematic upper trunk (UT), lower (LT), (LB), pelvis segments ergometer at 70% 100% peak power were captured. adjacent segments’ CV calculated using modified vector coding ...

Angular impulse generation is dependent on the position of the total body center of mass (CoM) relative to the ground reaction force (GRF) vector during contact with the environment. The purpose of this study was to determine how backward angular impulse was regulated during two forward translating tasks. Control of the relative angle between the CoM and the GRF was hypothesized to be mediated ...

Advanced rehabilitation strategies of the upper limb in stroke patients focus on the recovery of the most important daily activities. In this study we analyzed quantitatively and qualitatively the motor strategies employed by stroke patients when reaching and drinking from a glass. We enrolled 6 hemiparetic poststroke patients and 6 healthy subjects. Motion analysis of the task proposed (reachi...

INTRODUCTION Vascular patterns are important in the planning and performance of all upper abdominal surgical procedures. The coeliac trunk arises from the abdominal aorta and supplies the supracolic organs. Knowledge of variations of the coeliac trunk is important in procedures such as liver transplants for appropriate vascular ligation and anastomosis. METHODS The branching patterns of the c...

BACKGROUND The addition of Swiss balls to conventional exercise programs has recently been adopted. Swiss balls are an unstable surface which may result in an increased need for force output from trunk muscles to provide adequate spinal stability or balance. The aim of the study was to determine whether the addition of a Swiss ball to upper body strength exercises results in consistent increase...

We sought to determine the effects of varying the perceptual demands of a suprapostural visual task on the postural activity of children with developmental coordination disorder (DCD), and typically developing children (TDC). Sixty-four (32 per group) children aged between 9 and 10 years participated. In a within-participants design, each child performed a signal detection task at two levels of...

Introduction The brachial plexus is a complex structure which is divided into roots, trunks, divisions and cords. The brachial plexus is formed by the union of ventral rami of C5, C6, C7, C8 and greater part of T1.These ventral rami are the roots of brachial plexus, almost equal in size but variable in their mode of junction. Ventral rami of C5 and C6 unite at the lateral border of the scalenus...

Activity in human unmyelinated efferent nerve fibres was recorded from seven upper limb cutaneous nerve fascicles. The activity induced by contralateral nerve trunk stimulation or tone burst was averaged and could be compared providing the stimuli were delivered at random times and in a random sequence. The average evoked sympathetic nerve responses to nerve trunk stimulation and tone burst wer...
