El objetivo del estudio fue caracterizar mediante tecnología bidimensional los ángulos de flexión y extensión las articulaciones de los miembros anteriores y posteriores del Caballo Criollo Colombiano durante el andar paso fino. Se seleccionaron 32 ejemplares de ambos sexos, con edades entre 3 y 15 años, que habían participado en exposiciones equinas de grado A y B en la modalidad de paso fino. Los ejemplares presentaron una alzada de 138.35 ± 0.41 cm. Se instalaron marcadores reflectantes en puntos anatómicos palpables de las articulaciones de los miembros anteriores (hombro, codo, carpo y nudo) y posteriores (cadera, rodilla, tarso y nudo). El movimiento fue grabado con una cámara GoPro® de alta resolución (500 cuadros/segundo) mientras recorrían, montados por sus jinetes en una pista de 15 m de piso duro. Los videos fueron procesados con el software de captura de movimient...

A case of an 8-month-old Shih Tzu canine was referred to ASMEVET veterinary hospital in the city of Tunja, Colombia with a presumptive diagnosis of portosystemic shunt. The owner reported that the patient wanders at night, is not resting, has been vomiting, had convulsions and leaned his head against the walls.
