Low-Energy extracorporeal shockwave therapy improves locomotor functions, tissue regeneration and modulating the inflammation induced FGF1 and FGF2 signaling to protect damaged tissue in spinal cord injury of rat model: An experimental animal study.
Background: Spinal cord injury (SCI) is a debilitating condition that results in severe motor function impairments. Current therapeutic options remain limited, underscoring the need for novel treatments. Extracorporeal shockwave therapy (ESWT) has emerged as a promising noninvasive approach for treating musculoskeletal disorders and nerve regeneration.
Methods: This study explored the effects of low-energy ESWT on locomotor function, tissue regeneration, inflammation, and mitochondrial function in a rat SCI model. Experiments were performed using locomotor function assays, CatWalk gait analysis, histopathological examination, immunohistochemical and immunofluorescence staining.
Results: The findings demonstrated that low-energy ESWT had a dose-dependent effect, with three treatment sessions (ESWT3) showing superior outcomes compared to a single session. ESWT3 significantly improved motor functions (run patterns, run average speed, and maximum variation, as well as the Basso, Beattie, and Bresnahan (BBB) score) and promoted tissue regeneration while reducing inflammation. ESWT3 significantly decreased levels of IL-1β, IL6 and macrophages (CD68) while increasing leucocyte (CD45) infiltration. Additionally, ESWT3 upregulated NueN and mitofusin 2 (MFN2), suggesting enhanced neuronal health and mitochondrial function. Moreover, ESWT3 modulated the expression of fibroblast growth factor 1 (FGF1), FGF2, their receptor FGFR1 and phosphorylation of ERK, aiding tissue repair and regeneration in SCI.
Conclusions: This study highlights the potential of low-energy ESWT as an effective noninvasive treatment for SCI, demonstrating significant improvements in motor recovery, tissue regeneration, anti-inflammatory effects, and mitochondrial protection. These findings provide valuable insights into the mechanisms of ESWT and its therapeutic application for SCI recovery.
期刊介绍:
The International Journal of Surgery (IJS) has a broad scope, encompassing all surgical specialties. Its primary objective is to facilitate the exchange of crucial ideas and lines of thought between and across these specialties.By doing so, the journal aims to counter the growing trend of increasing sub-specialization, which can result in "tunnel-vision" and the isolation of significant surgical advancements within specific specialties.
