Caracterización biocinemática, al paso guiado a la mano, del caballo fino chilote

Abstract

SUMMARYIn the present study a description of some basic conformational and biokinematic characteristics of 16 mares that belong to the breed Caballo Fino Chilote was conduce, at the hand-led walk. The objective was to determine some conformational and biokinematic characteristics at the hand led walk for 16 mares and the possible aptitudes, of this breed, for being used as a therapeutic tool in hipotherapy activities. The conformational parameters were measured in vivo using a metric tape and ruler. For the time-related and biokinematic parameters, a 10m curtain graduated every 50 cm was specially made, in front of which each mare was guided at a hand-led walk while being filmed with a Sony Hi-8 camera. The video was transformed into photos using the Final Cut programme; 15 frames per second were obtained in JPG format; the frames were then passed into TIFF to measure the angular parameters with the help of the Scion Image programme. Lineal parameters were directly measured from the video using a Sony flat screen television. All data analysis was conducted with descriptive statistics using Microsoft Excel xp. The means obtained for conformational parameters were: height at the withers 117.94 cm (± 2.6), height at the back 113.3 cm (± 2.1), and height at the hindquarters 119.9 cm (± 3.1). For the lineal parameters the mean stride length was 135.3 cm (± 8.9) and the mean step length was 69.3 cm (± 5.8). The mean stride duration was 1.18 seconds giving a mean speed of 114.7 cm/sec. The angular parameters of the limbs were measured for the shoulder, elbow and carpus joints in the forelimb and for the hip, stifle and tarsus joints in the hindlimb, also the scapula and pelvis inclination were measured obtaining curves for each one along a complete stride cycle, and angular range of motion was determined.Palabras clave: caballo chilote, biocinemática, videografía, hipoterapia.

Descripción morfológica y biomecánica de la rodilla del caballo

“…Entre cada cóndilo femoral y tibial se localizan los meniscos los cuales corresponden a fibrocartílago en forma de C con bordes periféricos gruesos y áreas centrales cóncavas delgadas que compensan la falta de concordancia entre la tibia y fémur (5,32) . La unión de ambos meniscos insertos en las áreas intercondilares es por medio de los ligamentos meniscos tibiales craneales y caudales (2) .…”

Preliminary behavioural study of Caballo Fino Chilote stallions with restricted access to space and water during summer

“…It has also been described as a rustic, strong and tame horse (Mujica et al 2005), and with biokinematic characteristics, such as stride and step length, and conformational parameters, suitable for its use in hipotherapy (Escobar and Tadich 2006), although there are no studies about the breed's behaviour.…”

“…The CFCh is a unique equine resource; morphological characteristics (Voeltz 1996, Escobar andTadich 2006) and a genetic analysis (Barrera 1998) confirm that its origins comes from those equines from the Península Ibérica brought by the Spaniard conquerors between the XVI and XVII centuries (Escobar et al 1998, Mujica et al 2005 with a close relationship with the "Garrano" horse from Portugal (Mujica et al 2005). The main importance of the CFCh is that it is considered the only pony with Spanish origins subsisting in South America (Cothran et al 1993).…”

“…Mediante el uso de softwares como ImageJ y Kinovea, utilizando marcadores digitales colocados en los puntos articulares de las extremidades anteriores y posteriores del caballo [17], se encontraron distintas variables cinemáticas tales como las coordenadas espaciales de dichos puntos, la longitud de los segmentos corporales de las extremidades, así como los ángulos internos formados por éstas: A) falange distal-metatarso, B) metatarso-tibia, C) tibia-fémur, D) fémur-pelvis para la extremidad posterior; E) falange distal-metacarpo, F) metacarpo-radio, G) radio-húmero, H) húmero-escápula para la extremidad anterior, a lo largo de la marcha [18]. Estos ángulos sirvieron como guía para la colocación de los marcadores digitales, Error!…”
