AbstractMuscle injuries are frequent, both in the practice of exercises and in the work environment, and after the injury, healing begins. The inflammatory phase of muscle healing is accompanied by an increase in the production of reactive oxygen species (ROS), and a reduction in the antioxidant activity of defense enzymes. This imbalance between both can generate oxidative stress, which can cause oxidative damage by directly affecting vital cellular constituents, such as lipids, proteins and DNA, in addition to interfering negatively in the muscle cells differentiation . Therefore, substances or therapies that stimulate antioxidant repair and defense are crucial to keep the levels of free radical production low, and to minimize factors that delay or prevent tissue recovery, among these therapies photo biomodulation has stood out. The objective of this literature review is to clarify the FBM effect on oxidative stress and muscle repair. Therefore, a search was carried out in the databases of Pubmed, Scielo, Lilacs and PEDro, using the keywords “Photo biomodulation”, “low power laser”, “muscle repair”, “oxidative stress”, and in English were ”Photo biomodulation”, “low level laser therapy”, “muscle repair” and “oxidative stress”. The texts that addressed the research topic, published between 2000 and 2020, were chosen. After analyzing the articles, it was possible to observe that photo biomodulation, despite presenting a great variety of parameters, moment of application and irradiation protocol found in the literature, shows beneficial results in the repair muscle and in the reduction of oxidative stress and fatigue markers. Keywords: Low-Level Light Therapy. Oxidative Stress. Edema. ResumoLesões musculares são frequentes, tanto na prática de exercícios como no ambiente de trabalho, sendo que após a lesão, inicia a cicatrização. A fase inflamatória da cicatrização muscular é acompanhada do aumento da produção de espécies reativas de oxigênio (ERO) e uma redução da atividade antioxidante das enzimas de defesa. Este desequilíbrio entre ambos pode gerar o estresse oxidativo, que leva a danos e atingi diretamente constituintes celulares vitais, como lipídios, proteínas e DNA, além de interferir negativamente na diferenciação das células musculares. Portanto, substâncias ou terapias que estimulem a reparação e a defesa antioxidante são cruciais para manter os níveis de produção de radicais livres baixos, e minimizar os fatores que atrasam ou impedem a recuperação do tecido, dentre estas terapias a fotobiomodulação tem se destacado. O objetivo da presente revisão de literatura é esclarecer o efeito da FBM sobre o estresse oxidativo e o reparo muscular. Sendo assim, realizou-se uma pesquisa nas bases de dados da Pubmed, Scielo, Lilacs e PEDro, utilizando as palavras-chave “Fotobiomodulação”, “laser de baixa potência”, “reparo muscular”, “estresse oxidativo”, e em inglês foram “photobiomodulation”, “low level laser therapy”, “muscle repair” e “oxidative stress”. Foram escolhidos os textos que abordavam o tema da pesquisa, publicados entre 2000 e 2020. Analisando os artigos foi possível observar que a fotobiomodulação apesar de apresentar grande variedade de parâmetros, momento de aplicação e protocolo de irradiação encontrados na literatura, mostra resultados benéficos no reparo muscular e na diminuição de marcadores do estresse oxidativo e fadiga.

The objective of this review was to analyze original articles about the effects of therapy with LED in experimental models of calcaneal tendon lesions of rats. The search was performed in the period from February to May 2018, in the following electronic databases: MEDLINE, SciELO, and LILACS, besides the Google Scholar, using the descriptors “Achilles tendon”, “Rats”, “LED”, “Tendinopathy”, and “Low-level Light Therapy”, as well as their matching parts in the Portuguese and Spanish languages, related to and in association with the relevant terms to the content sought. From the descriptors used 215 works were found. After application of eligibility criteria 8 works were selected, in which positive results were found after the application of the LED. Regarding the main results found with phototherapy, we observed a significant reduction in inflammation. Only one article mentioned little reduction of inflammation. In relation to the number of sessions, there was wide variation, with an average of approximately 5 sessions every 24 hours. Studies in this review pointed out, therefore, positive results in the repair of the calcaneal tendon after therapy with irradiation LED; however, carrying out more experimental studies that help the standardization of parameters to be used in this therapy for further clinical studies becomes necessary.

Sleep disorders and depression are significant nonmotor symptoms (NMSs) of Parkinson disease (PD). However, few effective, evidence-proven medical treatments are available for alleviating these symptoms. Bright light therapy (BLT) is a well-established treatment for circadian rhythm sleep disorders and seasonal affective disorder. The present study conducted a literature review for the effect of BLT on PD, especially a meta-analysis of randomized controlled trials (RCTs). We searched for studies using the PubMed and Cochrane Library databases. The major outcomes were the effects on sleep and depression. The effect on motor symptoms was also analyzed as a secondary outcome. This study was registered with PROSPERO (CRD42020204454). Six studies were included in the literature review only, and the other five RCTs were included in the meta-analysis. Despite the positive effects of BLT on PD patients, which were demonstrated in noncontrolled studies, in the meta-analysis of the RCTs, BLT did not significantly improve the depressive symptoms (standardized mean difference (SMD): −0.15, 95% confidence interval (CI): −0.48 to 0.17, p = 0.36) and excessive daytime sleepiness (EDS) (SMD: −0.12, 95% CI: −0.49 to 0.25, p = 0.53) in PD patients. Regarding motor symptoms, no significant beneficial effects were conferred (SMD: −0.11, 95% CI: −0.44 to 0.21, p = 0.49). In conclusion, BLT did not significantly alleviate depression and sleepiness. The inconsistency between BLT protocols, such as the varied timing, dosages, and treatment durations, may render BLT’s efficacy difficult to demonstrate. The small effect size obtained from the present meta-analysis indicates that future RCTs are necessary, for which BLT protocols are standardized and more patients are enrolled to determine whether a significant therapeutic benefit was conferred.

Computerized auditory training (CAT) is a convenient, low-cost approach to improving communication of individuals with hearing loss or other communicative disorders. A number of CAT programs are being marketed to patients and audiologists. The present literature review is an examination of evidence for the effectiveness of CAT in improving speech perception in adults with hearing impairments. Six current CAT programs, used in 9 published studies, were reviewed. In all 9 studies, some benefit of CAT for speech perception was demonstrated. Although these results are encouraging, the overall quality of available evidence remains low, and many programs currently on the market have not yet been evaluated. Thus, caution is needed when selecting CAT programs for specific patients. It is hoped that future researchers will (a) examine a greater number of CAT programs using more rigorous experimental designs, (b) determine which program features and training regimens are most effective, and (c) indicate which patients may benefit from CAT the most.
