... ( Rattus norvegicus ) as they moved on horizontal poles of different diameters. The data were compared with data pertaining to terrestrial locomotion. We investigated three-dimensional kinematics and dynamics using biplanar cineradiography with simultaneous substrate reaction force (SRF) measurements...

... how gray short-tailed opossums( Monodelphis domestica ), which are generalized marsupials living on or near the ground, adjust to travel on rough and smooth 2 cm-diameter arboreal trackways. Limb contact position was determined via high-speed videography, and substrate reaction force was measured...

... increase their role in locomotion (as measured by craniocaudal and mediolateral substrate reaction forces) on challenging substrates while the hindlimb function remains relatively unchanged. It is possible that this pattern is comprehensive among primitive quadrupedal mammals in general, but comparative...

...Brigitte Demes; Kristian J. Carlson; Theresa M. Franz SUMMARY In an attempt to characterize more fully the variation in substrate reaction forces in the locomotor repertoire of primates, we recorded the forces involved in directional changes for two species. These are the first records of turning...

... on the arboreal trackway and laterally directed limb forces on the terrestrial trackway. We propose that the modifications in substrate reaction force on the arboreal trackway are due to the differential placement of the limbs about the dorsolateral aspect of the branch. Specifically, the pes typically made...
