Articular cartilage plays important roles in weight-bearing, lubrication, and load distribution in articulating joints. The tissue is mostly extracellular matrix (>90% by volume) that is synthesized and remodeled by cells (chondrocytes) embedded within. Ad ...
Probe (1) used during a total knee arthroplasty for measuring forces and locations of their points of application and thereby moments comprising A) two load sensitive plates (2 3) apt to be inserted in one joint-compartment of a knee joint each and each be ...
We hypothesized that the activation patterns of flexor and extensor muscles and the resulting kinematics of the forelimbs and hindlimbs during locomotion in the Rhesus would have unique characteristics relative to other quadrupedal mammals. Adaptations of ...
Cortical reorganization within the primary motor cortex (M1) contralateral to a practicing hand has been extensively investigated. The extent to which the ipsilateral M1 participates in these plastic changes is not known. Here, we evaluated the influence o ...
Motor responses evoked by stimulating the spinal cord percutaneously between the T11 and T12 spinous processes were studied in eight human subjects during walking and running. Stimulation elicited responses bilaterally in the biceps femoris, vastus lateral ...
Performing multi-joint arm movements in controllable dynamic environments during functional magnetic resonance imaging (fMRI) could provide important insights into the brain mechanisms involved in human motor control and related dysfunctions. In order to o ...
Reach-to-grasp tasks are composed of several actions that are more and more considered as simultaneously controlled by the central nervous system in a feedforward manner (at least for well-known activities). If this hypothesis is correct, during prehension ...
We investigated the patterns of vasomotion in various conduit arteries of the human arm. The internal diameter of the brachial, radial, ulnar, and digital artery was measured noninvasively in 17 healthy volunteers (aged 24-40 yr), using a high-precision ul ...
Genes of the HoxD complex related to the Drosophila Abd-B gene are involved in the morphogenesis of vertebrate paired appendages. Hoxd-11, for instance, is necessary in combination with other Hox genes for the proper development of different parts of the t ...
This study assesses (1) the relation of the very-low-frequency vasomotion (< 0.02 Hz) of the radial artery of young healthy volunteers to regional blood flow and (2) its distribution in the upper extremities. Radial artery diameters from comparable sites w ...
