LLLT

個人和家庭使用激光而不是藥物治療各種疾病，從頭痛，腰痛到失眠。 然而，面部麻痺患者認為骨性面管中的腫脹和神經炎受到LLLT的影響 兩組均接受了物理治療計劃。 另外，對照組接受安慰劑激光，而研究組接受連續紅外（IR）激光830nm，100mW，劑量為6.0J / cm2，在主要面部幹線和神經的四個運動分支上的五個點。 該研究持續四周，每週三次，每次持續60分鐘。 結果：結果顯示研究與對照組之間無顯著差異 families use laser instead of medication for variety of conditions ranging from  headache, low back pain to  insomnia . However, the swelling and the neuritis in the bony facial  canal is believed to be influenced by  LLLT  in patients with facial palsy Both groups received physical therapy program. Additionally, the control group received  placebo laser while the study group received continuous infrared (IR) laser 830 nm, 100mW with dose of 6.0  J/cm2, at five points overlying the main facial trunk and four motor branches of the facial nerve. The study  continued for four weeks, three times / week, every session continued for 60 minutes. Results: The results  revealed no significant difference between the study and the control groups ...

這與發光二極管（LED）形成對比。 術語“低水平”暗示存在具有最佳治療效果的特定波長的光，並且任何高於或低於此的水平可能不是精通的。 該治療窗的範圍大致為600至小於1,400nm，並且接近血紅蛋白和水的吸收光譜。 低水平光療法（LLLT）已被美國食品和藥物管理局（FDA）批准用於治療脫髮。 有幾種理論和LLLT的安全性和有效性的最小臨床證據，儘管大多數專家認為它是安全的。 需要更多的體外研究來闡明細胞水平的機制和有效性，並且需要更多的對照研究來評估這種新療法在一般人群中的作用。 This is in contrast to light emitting diode (LED). The term “low level” alludes to the fact there is a specific wavelength of light that has optimal therapeutic effects, and any level higher or lower than this may not be proficient. This therapeutic window ranges roughly from 600 to less than 1,400 nm, and is close to the absorption spectrum of hemoglobin and water. Ghanaat, Mahyar.
