Comparación de la cinemática de los miembros de dos especies de roedores histricognatos (Cuniculus taczanowskii y Dinomys branickii)

Quantifying the limb kinematics provide information on the locomotor behavior. Morphological differences lead to distinctiveness in the performance ability which in turn results in a diversification of habitat use. The comparative study of the fore and hind limb movements of two species of rodents is useful to recognize the basic principles of the locomotion of Cuniculus taczanowskiiand Dinomys branickii. To record the movements of both species photograms were used on which the angles were measured through the stance and swing phase. The comparison of different segments during the movement highlights the scapula and femur to produce most of the propulsion force in both species. The difference in amplitude of the joint angle and the length of time contact with the soil, contributes to the speed, breadth and strength of the movement of these species which allows them to make a differential use of the available habitat.
