LLLT

驗證LLLT對進行離心訓練的膝關節伸肌的肥大和強化的影響。 三組：對照組（CG），培訓組（TG）和培訓+ LLLT組（TLG）。 CG沒有接受干預，而TG和TLG參與了為期8週的膝伸肌等速離心訓練計劃。 在每次訓練之前，只有來自TLG的受試者用LLLT（波長= 810nm;功率輸出= 200mW;總劑量= 240J）進行治療。 通過超聲和等速測力分別評估膝伸肌厚度和峰值扭矩。   對於來自TG的受試者，肌肉厚度（15.4對9.4％），等長峰值扭矩（20.5對13.7％）和偏心峰值扭矩（32.2對20.0％）的TLG達到顯著更高的百分比變化。 在偏心訓練期間應用LLLT似乎可以改善健康受試者的肥厚反應和肌肉力量增加。 Verify the effect of LLLT on hypertrophy and strengthening of knee extensor muscles submitted to eccentric training. Three groups: Control Group (CG), Training Group (TG) and Training + LLLT Group (TLG). CG received no intervention, while TG and TLG were engaged on an 8-week knee extensor isokinetic eccentric training program. Only subjects from TLG were treated with LLLT (wavelength = 810 nm; power output = 200 mW; total dosage = 240 J) before each training session. Knee extensor muscle thickness and peak torque were assessed through ultrasonography and isokinetic dynamometry, respectively.  TLG reached signi...

對35名未經選擇的平均年齡為65歲的老年患者進行為期2年的前瞻性隨訪，他們訪問了我們的三級轉診疼痛中心，用低強度激光治療（LLLT）治療肩部疼痛性粘連性關節囊炎。從GaAIA半導體激光器裝置發射的波長為810nm，每點5.4J，功率密度為20mW / cm2，用於照射六個預定的解剖點和兩個穴位。治療方案包括每週三次治療，連續8週。每次治療持續180秒。使用Constant-Murley肩部評分進行連續臨床評估。 共有50個疼痛的肩關節得到治療，因為一些老年人出現雙側症狀。在8週的LLLT治療結束時，除了四個疼痛的肩膀以外，其他所有肩膀都顯示出Constant-Murley肩關節評分的顯著改善， 並且令人驚訝的是 ，在1年和2年的隨訪評估中發現了改善。 2-year prospective follow-up of a patient cohort of 35 unselected elderly patients with mean age of 65 years who visited our tertiary referral pain center for painful adhesive capsulitis of the shoulder managed with low-level laser therapy (LLLT).  Wavelength of 810 nm emitted from a GaAIAs semiconductor laser device with 5.4 J per point and a power density of 20 mW/cm2, was employed to irradiate six predetermined anatomic points and two acupuncture points. The treatment regimen consisted of three sessions of treatment per week for 8 consecutive weeks. Each treatment session lasted 180 seconds. Serial clinical assessment was undertaken using th...

如果嚴重的OM在放療期間發生得足夠早，或者如果延長或變得更加嚴重，則需要積極的管理 其中LLLT對老年患者的輻射誘導OM有影響...許多這些研究是在兒科和成人人群中進行的，但到目前為止，沒有一項研究專門評估接受RT治療的老年人的影響。 與安慰劑組相比，在激光中觀察到嚴重OM（p = 0.016）和嚴重疼痛（p = 0.023）和體重減輕（p = 0.004）的發生率和持續時間的顯著降低。 降低老年HNC患者的OM和口腔疼痛的嚴重程度。 where  LLLT  effects against radiation induced OM in  elderly  patients … Many of  these studies were done on the pediatric and adult population, but until now none of the studies  have specifically evaluated the effects in  elderly  people receiving RT  Significant reduction in the incidence and duration of severe OM ( p  = 0.016) and severe pain ( p  = 0.023) and weight loss ( p  = 0.004) was observed in laser than placebo group.

激光療法結合有氧訓練可以提供減少炎症標誌物的治療方法 老年運動和老年LLLT /運動組訓練6週。 在每次訓練期間，LLLT激光器在整個訓練過程中以808nm和4J的能量施加到指定的組。 對大鼠實施安樂死，收集肌肉組織和血清的肌肉橫截面積和IL-6和TNF-α蛋白質分析。 在VO2中顯示年輕和年齡對照組之間的統計學差異（用作基線）（p <0.05）。 與所有乾預組（運動，LLLT和LLLT +運動）相比，年輕對照組可以觀察到相同的差異 The aged-exercise and aged-LLLT/exercise groups were trained for 6 weeks. LLLT laser was applied before each training session with 808 nm and 4 J of energy to the indicated groups throughout training. The rats were euthanized, and muscle tissue and serum were collected for muscle cross-sectional area and IL-6 and TNF-α protein analysis. In VO2 showed statistical difference between young- and aged-control groups (used as baseline) ( p  < 0.05). The same difference can be observed in the young control group compared with all intervention groups (exercise, LLLT and LLLT + exercise) Amadio, Eliane Martins, et al.

我們提出了一個回顧性病例係列，使用高功率近紅外激光光療和IV級激光治療TBI。 與先前提出的雙峰模型相比，我們表現出更高的注量效力和更高的注量。 10例慢性TBI患者（平均傷後9。3年）在2個月內使用高功率近紅外激光進行10次治療（810 nm時為13.2 W / 0.89 cm2或810 nm時為9 W / 0.89 cm2和980 nm），頭痛，睡眠障礙，認知，情緒失調，焦慮和煩躁的症狀得到改善。 通過抑鬱量表和專門為本研究設計的新型患者日記系統監測症狀。 在810nm和980nm的功率範圍10-15W的NIR光可以安全有效地治療TBI的慢性症狀。 we present a retrospective case series using high-power NIR laser phototherapy with a Class IV laser to treat TBI. We demonstrate greater clinical efficacy with higher fluence, in contrast to the bimodal model of efficacy previously proposed. In ten patients with chronic TBI (average time since injury 9.3 years) given ten treatments over the course of 2 months using a high-power NIR laser (13.2 W/0.89 cm 2  at 810 nm or 9 W/0.89 cm 2  at 810 nm and 980 nm), symptoms of headache, sleep disturbance, cognition, mood dysregulation, anxiety, and irritability improved. Symptoms were monitored by depression scales and a novel patient diary system specifically designed for this study. NIR light in the po...

we are providing energy in the “ right ” wavelength for our purpose, let ’ s discuss energy delivery. Laser fluence is a measure used to describe the energy delivered per unit (or effective) area. Within the community of laser scientists and technicians it is very common to describe fluence in units of Joules per centimeter, squared (J/cm2). The important variables to consider when calculating fluence are 1) the shape of the beam (e.g. Gaussian, flat-top, semiconductor beam), 2) the distance to target, and 3) the duration of time the light is emitting (pulse width). Without delving into too much technical detail, the important thing to know about Gaussian beams is that the intensity of light is highest at point of origin. Consider Figure 1 to the left. The light is most intense at the peak of the curve, and loses intensity exponentially as it travels outward from the origin. This is a common shape for the output of laser diodes which commonly do not have focusing lenses....
