BIOMECHANIC PARAMETERS OF THE LATERAL AND MIDDLE GAIT MEASURED BY ANALOC-E WITH GAITED HORSES IN GERMANY Written by: A.P.Toledo Analoc-E coordinator and horse-gait researcher toledo@toledohorse.com.br.A Seminar of gait horse analysis using the Analoc-E System was carried out at Ferwick Farm indoor arena Erbach- Germany last february 2006. A good approach of the non invasive technology developed by Dr. A.P.Toledo (brazilian engineer and horse gait researcher) and Dr. C.A.Schelim (Engineer and Software Specialist) with 45 European gaited horse breeders which attended the meeting, despite of the cold weather and snow-capped roads.The event was nicely organized by Mrs. Caroline Jost and Marcel Kilbert with the Gaited Horse Breeders Association and Ferwick Farm team. The gait analysis were conducted with Islander, American Saddlebred , Manga-larga Marchador horses and gaited horses bread in Germany.The first gaited horse was an American Saddle (Two5) male with a good lateral (picada) gait. This gait showed two triple stances of foreleg (17.6 %), two triple stances of hindleg (23.1 %), two diagonal stances (23.1 %) and two lateral stances (36.1 %). The CL= 1.56 (Lateral Coeficient) is the relation between lateral/diagonal stance time. The dissociation of 26.1% and the asymmetry 0 % showed a good and smooth lateral gait. The stride time was 600.57 ms and there was no other non-desirable gait stance as mono, double fore, double hind, quadruple or even complete suspension. The average hoof stance time was 60.2 % or 361.54 ms.Next horse was a Mangalarga Marchador male performing a intermediary or middle gait. The gait diagram showed a good middle gait , with Handicap of 8.2, CL (lateral coeficient) of 0.905, stride length of 1.77m, body velocity of 11,01 k/h and a very nice asymmetry (As) of 1 % and two triple stances of foreleg (8.7 %), two triple stances of hind leg (14.4 %), two diagonal stances (40.4 %) and two lateral stances (36.5 %). The stride time was 583.44 ms and there was no other non-desirable gait stance as mono, double fore, double hind, quadruple or even a complete suspension. The average hoof stance time was 55.75 % or 355.27 ms. CONCLUSIONS: The typical gait average values are: 1 Diapason (stance/phase time) 1.49; 2 Triple stance 38.13%; 3 CL above 1.0 means lateral gait (picada) and the CL of 0,905 means a middle gait; 4 Stride lenght 1.63m; 5 Body velocity 10,14k/h; 6 Dissociation 26.42% (153.06 ms) (*) ; 7 Handicap 7.44; 8 Frequency (stride/min)103.62 ; 9 Stride duration 579.35 ms. (*) (ms) milisecond.To whoever could be interested on horse gait analysis, using a non invasive process, the author will be glad to furnish more details by email.
