    Terapia por fotobiomodulação em pontos de acupuntura associada ao exercício físico: implicações no tratamento de osteoartrite de joelho

    Knee osteoarthritis (OA) is one of the most common progressive degenerative joint diseases worldwide and also a major cause of disability and damage to quality of life. Photobiomodulation therapy (PBMT) through low-level laser, isolated or in association with physical exercise has shown to be a promising treatment and with good results for several chronic diseases, including changes that affect the articular system. The aim of this study was to evaluate the effects of laser PBMT applied to acupuncture points associated with a resistance exercise protocol on the level of pain in women with OA. 23 volunteers were randomized into 2 groups: Control group (Ex): volunteers were submitted to a resistance exercise protocol; Photobiomodulation Group (ExP): volunteers were submitted to a resistance exercise protocol associated with PBMT applied in acupuncture points. The interventions were performed twice a week for a period of 6 weeks, totaling 12 sessions. The exercise program consisted of warming up, muscle strengthening (hip and knee flexors and extensors, hip adductors and adductors) and stretching of the main muscle groups of the lower limbs (lower limbs). PBMT (808 nm, 100 mW, 4 J in) was applied to 5 acupuncture points of the affected knee right after each exercise session. For assessment and reassessment, the numerical rating scale for pain (NRS) was applied; functionality and quality of life questionnaires (Western Ontario and MacMaster Universities Osteoarthritis Index [WOMAC]); functionality (Lequesne); physical performance tests (Timed Up and Go [TUG], Short Physical Performance Battery [SPPB]), lower limb strength and endurance (30-second sit-up test). The results show that both Ex and ExP showed a lower rate of pain, higher scores in the tests of strength and endurance, in functionality, in physical performance, mobility and balance and in WOMAC to its initial rates when compared to the final ones. However, no difference was observed between the experimental groups. Thus, it can be concluded that both PBMT in specific acupuncture points in association with physical exercise, as well as applied exercise in isolated way, show analgesic effects and have positive effects on physical capacity and quality of life in patients with OA.

    Influência da Terapia por Fotobiomodulação no tratamento de condições inflamatórias pulmonares e seu impacto sobre o Covid-19
    (Universidade Brasil, 2021) Macedo, Daniela Bezerra; Tim, Carla Roberta; Garcia, Lívia Assis
    Today we are facing a pandemic that continually causes high rates of deaths and catastrophic and countless economic and psychosocial consequences. Thus, this period requires a rapid search for viable procedures that can allow us to use safe and noninvasive clinical tools as prophylactic or even adjuvant methods in the treatment of COVID-19, thus constituting an important challenge to the medical clinic. Evidence shows that photobiomodulation therapy (PBMT) is shown to attenuate the inflammatory process and reduce respiratory disorders similar to acute lung injury (ALI), complications associated with infections, such as that caused by the new Coronavirus (SARS-CoV-2). Thus, the aim of this study was to evaluate the influence of laser PBMT on infrared length in the treatment of ALI, one of the main critical complications of COVID-19 infection, in an experimental model of rats. Twenty-four male Wistar rats were randomly allocated into three experimental groups (n = 8): Control (CG); LPA (LPA); LASER-treated LPA (LPAL). For the treatment, a laser equipment (808 nm; 30 mw; 1.8 J) was applied at three points (anterior region of the trachea and in the venereal regions of the thorax bilaterally) in the period of 1 and 24 hours after lpa induction. Descriptive histopathological analysis, lung injury score, analysis of the number of inflammatory cells, interleukin 1 β (IL-1β) and interleukin 10 levels (IL-10) were performed for treatment evaluation. In the results, it was possible to observe that the treatment reduced inflammatory infiltrates, there was thickening of the alveolar septum and the pulmonary injury score when compared to the LPA group. In addition, laser PBMT showed lower immunoexpression of IL-1β, however, it did not alter the levels of pulmonary IL-10. Thus, it can be concluded with this experimental study that infrared laser PBMT was efficient in attenuating ALI, one of the main complications of COVID-19, since it was able to reduce the inflammatory process, as well as increase the production of anti-inflammatory cytokines.
