Effects of radial shockwave therapy on the limb function of dogs with hip osteoarthritis

Abstract

The objective of this study was to evaluate the effects of extracorporeal radial shock wave therapy on the hindlimb function of dogs suffering from hip osteoarthritis. Twenty-four client-owned dogs with hip osteoarthritis were investigated; 18 of them received radial shockwave therapy and six were left untreated as controls. Force plate analysis on a treadmill was used to assess the dogs' hindlimb function before treatment and four weeks after the last treatment, and the treated dogs were re-evaluated three and six months after the treatment. The parameters chosen for evaluation were peak vertical force and vertical impulse, and the calculated symmetry indices. In the treated dogs, differences between the ground reaction forces exerted by the right and left hindlegs disappeared four weeks after the treatment, whereas in the control dogs only the peak vertical force distribution changed significantly. The significant improvement in the treated dogs was confirmed by changes in the symmetry indices. Significant improvements in vertical impulse and peak vertical force were observed three months after the treatment.

Extracorporeal Shockwave Shows Regression of Osteoarthritis of the Knee in Rats

“…Frisbie et al [15] reported that ESWT significantly improved the degrees of lameness in horse, but no disease modifying effects as evidenced by synovial fluid analysis, synovial membrane, or cartilage. Mueller et al [16] demonstrated that ESWT significantly improved the limb function of dogs with hip osteoarthritis with the difference in ground reaction force between two limbs disappeared in four weeks after treatment. Ochiai et al [17] showed that ESWT is a useful treatment for knee OA with improvement in walking ability and reduction of calcitonin generelated peptide (CGRP) in dorsal root ganglion (DRG) neurons innervating the knee.…”

Changes of articular cartilage and subchondral bone after extracorporeal shockwave therapy in osteoarthritis of the knee

“…Frisbie and colleagues reported that ESWT improved the degrees of lameness in horse, but no disease modifying effects as evidenced by synovial fluid analysis, synovial membrane or cartilage 19. Mueller and colleagues demonstrated that the limb function of dogs with the difference in ground reaction force between two limbs were improved after ESWT in hip osteoarthritis 20. Ochiai et al showed that ESWT is a efficient treatment for knee OA with improvement in walking ability and the reduction of calcitonin gene-related peptide in dorsal root ganglion neurons innervating the knee 21.…”

Next-generation Sequencing Identifies Articular Cartilage and Subchondral Bone Mirnas after ESWT on Early Osteoarthritis Knee

“…ESWT has shown effectiveness in many orthopedic disorders including soft tissue tendinopathy and non-union of long bone fractures [12,13]. In addition, many studies including ours reported positive effects of ESWT in various arthritic joints in animals [14][15][16][17][18]. Our previous studies demonstrated that ESWT is chondroprotective in the initiation of OA changes of the knee [19,20], and induces regression or retardation of established OA changes of the knee in rats [21].…”
