The effect of focused extracorporeal shock wave therapy on collagen matrix and gene expression in normal tendons and ligaments

Abstract: The observed disorganisation of the collagen network warrants caution when using ESWT. Exposing noninjured tissue to ESWT should be avoided and it may be advisable to restrict exercise in recently treated patients. However, the induced tissue disorganisation might also be a trigger for repair in chronic tendinopathies.

“…Therefore, a possible mechanism for the upregulation of lubricin expression by ESWT involves the induction of appropriate cytokines: ESWT may increase TGF-β and BMP-7 expression in fibroblast-like cells in tendons and septa, which in turn increases lubricin expression in the local tissue. Additionally, ESWT has been hypothesized to induce an acute biochemical activation of latent matrix metalloproteinases (MMPs) (Bosch et al 2009). MMPs are known to activate latent TGF-β sequestered in the ECM (Jenkins 2008), possibly leading to lubricin upregulation.…”

“…17 The anti-inflammatory effects, both trophic and metabolic rise subsequently and induce a more stable therapeutic effect. 4,18 The subjects in the supplement group showed better pain regression in the later followups even though there were no significant differences between the two groups. This result can be understood considering that neurotrophics need more time to optimize therapeutic effects.…”

“…Adverse reactions such as pain, increased lameness, hematoma and inflammation have been reported in horses. Studies on focused ESWT show a disorganization of collagen network in the treated normal tendon 38 , as well as a potential to increase bone microcracking 39 . These studies recommend restricted exercise after treatment.…”

“…Normal tendons treated with ESWT showed a transient stimulation of metabolism in tendinous structures, but six weeks after treatment the metabolism and level of glucosaminoglycans was lower than before treatment. 38,39 Shockwaves may affect sensory nerve fibers, resulting in an analgesic effect. No cutaneous analgesia or changes in measured gait analysis parameters were recognized following ESWT treatment of equine high palmar/plantar metacarpal/metatarsal pain, but reduced gait asymmetry was found at 72 hours following treatment.…”
