The Evidence is In….the latest research demonstrates efficacy of VersaTron4Paws Extracorporeal Shock Wave Therapy (ESWT) for multiple canine indications
A prospective clinical study evaluating the efficacy of ESWT for the treatment of shoulder instability is currently be conducted by Michael Kowaleski, DVM, DACVS and DECVSand Robert McCarthy, DVM, DACVS at TUFTS Cummings School of Veterinary Medicine. VersaTron 4 Paws ESWT is being used for the treatment of biceps tenosynovitis, and/or shoulder instability which typically includes medial glenohumeral ligament laxity/rupture and subscapularistendontear. The diagnosis is made on the basis of chronic lameness related to the shoulder that is refractory to rest and treatment with NSAIDs, shoulder pain on exam, radiographs, biceps tendon (near the shoulder) ultrasound, and shoulder arthroscopy. Patients are treated with 750 pulses at Energy level E4 with the R05 trode and they receive 3 treatments at 2-3 week intervals. Clinical results have been very promising.
A retrospective study is currently being conducted at Surgical Group For Animals, CA by Edward Leeds, DVM, DACVS and Young Joo Kim, DVM DACVS. Of the 23 owners surveyed, all reported that their dogs were more comfortable following ESWT and showed less reluctance to sit or lie down or to get up from one of these positions. Three out of four of the owners surveyed reported that they observed ESWT to be more effective for their pet than other treatment modalities and over 90% would use ESWT again if needed. Typically only 1-2 treatments are needed for this indication. Dogs are treated with 500-1000 shocks with the R20 trode at Energy level 5-6.
Chronic Wounds / Lick Granulomas
Pam Nichols DVM, CCRP, of K-9 Rehab Center, Bountiful, Utah reports excellent results when using ESWT for infected wounds and lick granulomas. For example, Dr. Nichols recently used ESWT to treat a chronic lick granulomaof approximately 2 years duration for which for which steroids and DSMO had been unsuccessful. With two treatments of 500 pulses, E2, at two weeks apart, the lesion resolved completely. At four months post-treatment there had been no further licking or irritation of the lesion and the hair had completely re-grown.
In another case, ESWT was used to treat a severe wound/osteomyelitis case. Following two treatments of ESWT at levels E3-E5, 500-750 pulses, the wound was healing well, and the limb was saved.
ESWT is often a first-line therapy for treatment of difficult chronic wounds in human and equine patients. ESWT has shown to be particularly beneficial in the treatment of equine distal limb wounds that often do not heal. A prospective study at Iowa State University demonstrated significant improvement in distal limb wound healing with ESWT. ESWT use in canine patients continues to grow due to its antibacterial effects and promotion of proper wound healing with reduced scaring.
Post Surgical Tendinitis and Ligament Inflammation
A prospective clinical trial is currently being conducted by Alan Cross, DVM, DACVS at Georgia Veterinary Specialists using ESWT for the treatment of patellar ligament desmitis following TPLO.The protocol for this indication is 600 pulses at Energy level E6 using the R05 trode at 4 and 6 weeks post-surgery
