INTRODUCTION Patients with chronic low back pain (CLBP) often demonstrate altered timing of thorax rotations in the transverse plane during gait. Increased axial trunk stiffness has been claimed to cause this movement pattern. OBJECTIVES The objective of this study was to assess whether axial trunk stiffness is increased in gait in CLBP patients. METHODS 15 CLBP patients and 15 healthy cont...

BACKGROUND There is limited information regarding the mechanical factors contributing to the progression of posterior tibial tendon dysfunction. Therefore, an investigation of the mechanical forces on the posterior tibial tendon may improve our understanding of this pathology. METHODS The gliding resistance and excursion of the posterior tibial tendon in the retromalleolar region was measured...

OBJECTIVE To determine whether trunk position sense is impaired in people with poststroke hemiparesis. BACKGROUND Good trunk stability is essential for balance and extremity use during daily functional activities and higher level tasks. Dynamic stability of the trunk requires adequate flexibility, muscle strength, neural control, and proprioception. While deficits of trunk muscle strength hav...

the evolution of texture was discussed during the formation of ultra-fine and nano grains in a magnesium alloy severely deformed through accumulative back extrusion (abe). the microstructure and texture obtained after applying multiple deformation passes at temperatures of 100 and 250°c were characterized. the results showed that after single abe pass at 100°c an ultrafine/nano grained microstr...
