Low Level Laser Therapy Essay

The word laser is an acronym for, “Light Amplified by Stimulated Emissions of Radiation”, this means that all the lights in a laser have the same wavelength. Within a century of the laser being invented it occupied a major role in scientific research, medicine, industry, and even daily life. Lasers are used in the medicine field for procedures such as, laser eye surgery, heart, stomach, and intestinal surgeries. These procedures laser procedures are said to be harmless. Major factory industries use lasers to cut many things ranging from thin

Physical therapy modalities, such as ultrasound, whirlpool baths, phonophoresis, augmented soft tissue mobilization, electrical stimulation, and unweighted ambulation, may be used (2009). Ice and rest are the two most important treatments the athlete can receive during the acute phase. Ultrasound will be used to increase the tempeture of the local area. This will increase the speed of healing. Phonophoresis will be used to introduce medications into the area. Mainly anesthetics to numb the trigger point. Whirlpool baths will be used to relive pain and swelling of injured leg. Electrical stimulation is used for to help the healing process by transporting ions beneficial to healing to the affected area

The results of this study show that both treatment interventions are just as effective in pain reduction and increased spinal mobility following a single treatment. A post boc correlation (relationship between variables) analysis was performed in order to explore the relationship between changes in pain and lumbar extension motion. Researchers analyzed the relationship between an increase in motion and decrease in pain for this study.

Laser resurfacing is another treatment which has taken the cosmetic world by storm in recent years. While it might be more recognisable as a wrinkle eliminator or a tattoo remover, the use of it to treat acne sufferers is remarkable. The laser beams essentially destroy the epidermal layer of the skin, this then allows new skin to generate and fill the pits created from acne

The strength of this recommendation is inconclusive. As practitioners, we should have minimum restraint in following this recommendation and should be on the lookout for new evidence in addition to strongly listening to patient preference. This recommendation is based upon three RCT’s. Two of these studies were of high strength and one was of moderate strength with regard to quality. All three of these studies had moderate applicability. In these studies, pain improvement was not consistently statistical significant (MD = .81, 95% CI -1.76, .14; MD = 2.26, p<.001; MD = -.82, 95% CI -1.247, -.39), and neither was function (MD = 3, 95% CI -1.05, 7.05; MD = 6.54, p=.001). In addition, the authors concluded the clinical significance of these findings were

The aim of the study is to evaluate the clinical efficacy of a soft tissue 980-nm diode laser with SRP versus the effects of SRP alone.

The participants recorded their pain during activity using the numerical rating scale (NRS) during the initial examination. The participants received three IASTM treatments a week

Evidence from this study suggests only the short term effects of LASER. Further studies could include patients randomized by levels of baseline disability and duration of symptoms. Studies which states the long term effect of LLLT should be emphasized. Further, studies should evaluate many factors such as psychosocial aspect and dosiometry that may reflect on treatment response and recovery. The complete substitution of anti inflammatory drugs by LLLT, in patients that are at high risk, should also be targeted in future

Of the RCTs with significant data, the majority of interventions slowly increased the level of resistance as the intervention progressed (Andersen, et al., 2012; Caputo, Bari, & Orellana, 2017; Jay, et al., 2011). However, one intervention tested two groups against one other where one underwent progressive change and the other remained at a fixed level of resistance and despite finding a significant decrease in pain symptoms overall did not find a significant difference between the two groups (Li, et al., 2017). This suggests that it is not critical to increase difficulty during the intervention, to achieve relief from neck/shoulder pain. A few of the RCTs were also measuring increases in strength, wherein an increase in resistance may be necessary to continually build strength, but it is not necessary for pain relief. It may also potentially put individuals at risk of more

A study conducted by Deyle et al.7 took 83 patients approximately 60 years old with osteoarthritis in the knee and split them into a treatment group and control group. The treatment group received manual physical therapy, which consisted of stretching, ROM, and strengthening exercises, while the placebo group was given a non-therapeutic amount of ultrasound. Participants were required to attend physical therapy appointments twice a week for four weeks. Data was collected at baseline, four weeks, and eight weeks using a six-minute walk test, and the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) as outcome measures. Participants in the treatment group saw both clinical and significant differences in their WOMAC scores and the six-minute walk test at the eight-week time period. This study demonstrates that participating in physical therapy can help manage OA symptoms in the knee.7 Another study conducted by Palmer et al.11 looked at the intervention of transcutaneous electrical nerve stimulation (TENS) to see if it relieved symptoms of knee OA. Even though the main purpose of this study was looking at the TENS therapy, the control group was given a six- week physical therapy exercise program. The study also used the WOMAC scale and the control group actually showed improvements .11 The knee group had 41.6% of its participants reaching

Permanent Hair Removal: Laser hair removal changes peoples' lives every day. After only a few sessions of this cutting edge procedure, you will be finished with things like shaving, waxing, sticky residues, and stubble. With laser hair removal, you will enjoy results that last a lifetime.

Other skill-based approaches include massaging, IV therapy, and hypnosis. A few studies have exclusively explored the importance of massaging as a treatment option for SCD pain. Williams and Tanabe (2016) included only three massage studies, and all achieved significant pain reduction. None of the studies was conducted in the past five years indicating that evidence on massage therapy is limited.

Th is local application reduces pain transmission from the wound and suppresses the local infl ammation that may occur in response to the injury. LAs can be administered at the end of the surgical procedure to infuse the wound through catheters and/or as single-dose infi ltrations [4]. Th e introduction of wound infi ltration with LAs not only provides this much-needed alternative analgesia but, in fact, in some cases, provides superior analgesia [5].

Tissues preferentially absorb light at varying wavelengths. Light has dual nature as described in Physics. When it is travelling, it is considered to be continuous wave but when it strikes a tissue or a surface it is considered as particle named as Photon: a pocket of energy2. Laser photons that travel through a given tissue with a high absorption coefficient for its specific wavelength will lose energy through absorption easily. Because these photons are readily absorbed, this light travels much shorter distances than those light wavelengths that are not absorbed. The absorption of photons from initial ray of laser eventually degrades the power of light with distance travelled. Absorption coefficient for the various tissues is lesser at the wavelength of light between 600 to 900 nm, which means better tissue penetration is seen in lasers with these
