RE: [RC] hard roads effect, lameness - Linda CowlesOkay, here's the research: Scientist Luca Bein at the University of Zurich in 1983 brought to light interesting findings about shock absorption in the hoof, comparing it in unshod and shod (with various materials) hooves. According to his study, a hoof shod with a normal metal shoe lacks 60-80% of it natural shock absorption. He also found that "A shod foot moving on asphalt at a walk receives three times the impact force as an unshod foot moving in on asphalt at a trot." Another study in 19190 by Rudolf Zierold, working at the institute of Professor Lungwitz in Dresden, published the dissertation "About the Sensitive and Insensitive Laminae of the corium of the Horse". Zierold found that, in outwardly appearing perfectly healthy, shod hooves, the sensitive laminae showed a significant increase in structural alterations when compared to that of unshod hooves, regardless of the age of the horse. He furthermore stated that the implications of structural alterations in the lamellae of the corium are serious and far-reaching, when one considers that the entire weight of the horse (and far more, at faster gaits or jumps) is suspended by this connection between laminar corium and laminar horn (ie. The connective layer between the coffin bone and hoof capsule). Any pathological alterations from the normal, healthy structure predisposes toward numerous hoof problems (for example, coffin bone rotation).
