Mechanical Stochastic Resonance Therapy Restores Joins and Muscle Injuries on Standard-bred Races Horses

Previous studies showed that the Infratonic Stochastic Resonance (SR) therapy increases race performance on standard-bred horses and decreases the risk of inflammation and muscle injury. In the present study we continued investigating the benefits of this therapy on standard-bred racehorses. We expand the research to the analysis of the hyaluronic acid levels and the quality of the synovial fluid within the hocks using the same therapy modality as in the previous study. We also investigated the effects of the therapy on the levels of aspartate aminotransferase (AST) and creatine phosphokinase (CPK) in serum when the therapy was applied from a distance and compare with previous results where the therapy was applied directly to the skin of the horse two times per week. For the therapy from a distance one group of 10 horses was treated from 4 to 11 feet four hours per day, while the second group of 10 horses was used as the untreated control. After 6 weeks of treatment the levels of CPK in serum decrease significantly while the decrease in ASP levels was not significant. Comparing with previous results we found that the changes in CPK and AST levels are more pronounce when the therapy is applied directly to the skin of the horse. On the other hand, we found that the therapy raised the amount of hyaluronic acid within the treated hock within a 15% average, while the untreated hock presented an average decrease of 18%. The therapy also improves the quality of the synovial fluid increasing its volume, viscosity, and clarity. These results indicate that the Infratonic SR therapy normalizes cellular activity in stressed tissue increasing the production of hyaluronic acid and improving the quality of the synovial fluid. We also demonstrated that the Infratonic SR therapy is effective when applied a few feet distance from the horses, finding a statistical significant decrease of CPK in serum. _________________________________________________________________________
