什麼是「#低能量體外震波治療」?
低能量體外震波治療(low-intensity extracorporeal shockwave therapy,簡稱LI-ESWT),為一種非侵入性治療,因具有刺激治療部位產生新血管增生作用。
台灣於2015年3月由衛生福利部正式核准,可運用於泌尿科治療男性「血管性勃起功能障礙」等適應症。
目前衛生福利部正式核准的「低能量體外震波儀」分為二種:
一種為「線性震波」,另一種為「單點聚焦震波」。
「低能量體外震波治療」對於「勃起功能障礙」的作用機制
引用醫學文獻跟大家分享,「低能量體外震波治療」對於「勃起功能障礙」的作用機制,主要是因為「震波治療」可以誘導陰莖的血管生成及血管再新生。
[Wang et al. 2003]發現「低能量體外震波治療」可以刺激「血管新生相關的生長因子」表現,例如
#endothelial nitric oxide synthase (eNOS)
#vascular endothelial growth factor (VEGF)
#endothelial cell proliferation factors
研究指出,在接受「低能量體外震波治療」後一週「血管新生相關的生長因子」濃度會顯著提高而且可以持續八週。「血管再新生」及「細胞增殖」在接受「低能量體外震波治療」後四週呈現,而且可以持續十二週。

Research on the biological effects of LI-ESWT has mainly been focused on vasculogenesis and local neovascularization. Wang and colleagues [Wang et al. 2003] discovered that LI-ESWT stimulates the expression of angiogenesis-related growth factors, such as endothelial nitric oxide synthase (eNOS) and vascular endothelial growth factor (VEGF), and endothelial cell proliferation factors, such as proliferating cell nuclear antigen (PCNA). They also reported that LI-ESWT induces neovascularization, and consequently improves blood supply. Interestingly, they found that 1 week after LI-ESWT, the angiogenic marker levels rose significantly and this effect lasted for approximately 8 weeks. They also showed that neovascularization and cell proliferation were evident 4 weeks after LI-ESWT and persisted for more than 12 weeks

「低能量體外震波治療」除了誘導「血管再新生」外,
還可以誘導一氧化氮的釋放,引發陰莖海綿體內的平滑肌放鬆,讓血流灌注。
摘錄了一篇醫學文獻,
男性勃起的生物機轉為,「大腦」發射出訊號,經由「脊髓」,再經由「副交感神經」引發出一氧化氮(nitric oxide, NO)的釋放,NO這個神經傳導物質,進而引發陰莖海綿體內的平滑肌放鬆,讓血流灌注。
但當陰莖勃起時,動脈灌注至陰莖的血流會增加,海綿體內的血管竇因而膨脹導致壓力變大,連帶使包覆在陰莖海綿體的白膜往外擴張,而壓迫周圍的靜脈,最先被壓迫的是與白膜相連的許多穿出靜脈,然後是外圍的深層背靜脈、海綿體靜脈、動脈旁靜脈等。

動物文獻研究:
經由「#低能量體外震波治療」,可以「在原本位置」的陰莖處活化「前驅細胞」(Progenitor Cells)也就是「幹細胞」,以達到再新生的功能。

根據醫學研究:
"低能量體外震波治療"是藉由啟動「腦源性神經營養因子」
醫學百科:
腦源性神經營養因子(英語:Brain-derived neurotrophic factor)是人腦中的一種蛋白質,由腦源性神經營養因子基因生成。 腦源性神經營養因子是神經營養因子中的一種,這種因子存在於人的神經系統中。
在中樞神經系統發育過程中,對神經元的存活、分化、生長發育起重要作用,並能防止神經元受損傷死亡、改善神經元的病理狀態、促進受損傷神經元再生及分化等生物效應,而且也是成熟的中樞及周圍神經系統的神經元維持生存及正常生理功能所必需。

Low-intensity extracorporeal shock wave therapy (Li-ESWT) is used in the treatment of erectile dysfunction, but its mechanisms are not well understood. Previously, we found that Li-ESWT increased the expression of brain-derived neurotrophic factor (BDNF)

Extracorporeal Shock Waves Therapy Delivered by Aries Improves Erectile Dysfunction in Spontaneously Hypertensive Rats Through Penile Tissue Remodeling and Neovascularization.
CONCLUSIONS:
Li-ESWT by Aries may represent an effective noninvasive therapeutic alternative and a relevant add-on therapy to phosphodiesterase type 5 inhibitors for ED in hypertensive patients, and it is suggested that it acts via remodeling of the penile tissue and promoting cavernosal
