“…This is partly because there are many contributing factors to PSF 8 , 10 – 32 , and each research team may focus only on some of the factors to find a route for preventing, treating or managing PSF. Any endeavour to find the most effective intervention in the research literature leads to a collection of heterogeneous interventions from physiotherapy 33 and exercise 34 – 38 to psychotherapy, pharmacotherapy, and recently laser therapy 39 – 41 .…”

Post-stroke fatigue: a scoping review

et al. 2020

Background: Post-stroke fatigue (PSF) is one of the most common and frustrating outcomes of stroke. It has a high prevalence and it can persist for many years after stroke. PSF itself contributes to a wider range of undesirable outcomes that affect all aspects of daily life. The aim of this review was to identify and summarise the most recent research on PSF, in order to update the evidence base. Methods: We updated an existing review (Hinkle et al. 2017) systematically searching CINAHL, MEDLINE, PsycINFO, and PubMed to cover new research studies between 1st March 2016 and the search date (19th January 2020). We included interventional and observational research, and clinical practice guidelines that were not covered in the original review. After duplicate removal in EndNote, two reviewers screened the search results in Rayyan, and data from eligible full texts were extracted onto an Excel spreadsheet. Finally, we used RobotReviewer and a human reviewer to assess the risk of bias of randomised trials for this scoping review. Results: We identified 45 records for 30 studies (14 observational, 10 interventional studies, and 6 guidelines). Apart from one, the interventional studies were single-centred, had high risk of bias and small sample size (median 50). They investigated exercise, pharmacotherapy, psychotherapy, education, and light therapy. Observational studies mainly reported the factors related to PSF including co-morbidities, depression and anxiety, quality of life, activities of daily living, stroke severity, medication use and polypharmacy, polymorphism, pain, apathy, limb heaviness, neuroticism, mobility, and thyroid-stimulating hormone. Guidelines either did not report on PSF or, when reported, their recommendations were supported by little or low level of evidence. Conclusion: Although we identified a number of recent studies which have added to our current knowledge on PSF, none are robust enough to change current clinical practice.

“…Impairment of basic motor functions, such as muscle weakness in limbs affected by spasticity, leads to peripheral fatigue and impaired functionality. According to [128], the clinical use of PBM has provided major advances in the treatment of muscular disorders and prevention of muscle fatigue. Their study were structured with 10 sessions of PBMT (laser 100 mW, 808 nm, 159.24 J/cm 2 /point, 5 J/point); PBM active or placebo was associated with exoskeleton-assisted functional treatment.…”

Peripheral muscle fatigue is a common experience in daily life. Every individual at some point in their life has realized the inability to maintain muscle contraction, a phenomenon known as fatigue. Interestingly, neurological patients with peripheral sequelae such as spastic muscle contraction are able to remain in a pattern of muscle contraction for prolonged periods. The effects of laser therapy are already recognized in muscle contraction to delay skeletal muscle fatigue, prolong physical activity, and reduce delayed onset muscle soreness. However, the effects of photobiomodulation on neurological patients with muscular spasticity are still not well established. The present literature review seeks to recognize articles about the application of laser irradiation, also known as photobiomodulation, to patients with muscle fatigue and/or spastic palsy. To perform a literature review, we used the systematic review methodology for the literature search. The following keywords were searched: (skeletal muscle fatigue) AND (spastic patients) AND (low-level laser therapy OR low intensity laser therapy OR low energy laser therapy OR LLLT OR LILT OR LELT OR infrared laser OR IR laser OR diode laser), and these were used for search on the following databases: PubMed, Embase, Web of Science, BIREME, Scopus, and SciELO. Besides that, a literature review concerning on muscle physiology, fatigue, and LLLT was made. No language filter was applied, and altogether, 689 papers were identified. A group of 3 physiotherapists and 01 pharmaceutical scientist performed the literature review, and every exclusion was confirmed by at least two reviewers. After inclusion and exclusion criteria, 128 studies were included in this review. Conclusion, the LLLT can contribute to the recovery of spastic patients and muscles in fatigue. However, the real effect of laser photobiomodulation on muscle spasticity remains to be established. Only a much reduced number of clinical trials have been performed with a small number of participants. There is a lack of clinical trials from different research groups that could help to understand and elucidate the effects of laser in prolonged muscle contraction in spastic palsy.

“…A aplicabilidade da Terapia Laser de Baixa Intensidade (TLBI) ou Fotobiomodulação (FBM), como é conhecida atualmente, tem se mostrado efetiva dentro do processo terapêutico para objetivos que variam desde cicatrização de feridas, alívio de dor crônica e processos inflamatórios, diminuição da fadiga, diminuição de marcadores bioquímicos pós exercícios à melhora do desempenho muscular de indivíduos sadios e neurológicos (LEAL JUNIOR et al, 2010;DE MARCHI et al, 2011;ALMEIDA et al, 2011;CHAIEB et al, 2015;REIS et al, 2015;NAMPO et al, 2016;MONICH;BAVRINA;MALINOVSKAYA, 2018;NEVES et al, 2020).…”

As doenças neurológicas geralmente estão associadas a importantes déficits funcionais, dificultando a execução de atividades de vida diária e autocuidado. Pesquisas recentes demonstram efeitos positivos da Fotobiomodulação Transcraniana (FBM-T) para estimulação do tecido cerebral. O estudo teve como objetivo avaliar os efeitos da FBM-T associada ao treinamento aeróbico na função do sistema musculoesquelético de indivíduos com lesões neurológicas crônicas. Participaram deste ensaio clínico duplo-cego 16 voluntários com diferentes lesões do SNC, de ambos os sexos, idade média de 51,9±13,9 anos e marcha preservada. Os voluntários foram divididos aleatoriamente em 2 grupos (Treino FBM-T ativo + treino aeróbico e FBM-T placebo + treino aeróbico). O programa de reabilitação foi realizado em esteira ergométrica, na frequência de 2 vezes semanais e com duração total de 12 semanas. A FBM-T (3 lasers no λ= 660nm e 3 Lasers no λ= 808nm, 100mW, 6J/laser, 60seg/ponto, 36J por ponto, energia total 108J/cm2) foi aplicada em 3 pontos, sendo estes Fz, F7 e F8 segundo o Sistema Internacional 10-20 de EEG. Foram avaliados RMS do músculo reto femoral parético ou de maior comprometimento no pré-tratamento, 8ª semana e 12ª semana. Nota-se um aumento da atividade elétrica do grupo Laser nas coletas de RMS isotônica e isométrica, e redução do recrutamento muscular em ortostatismo quando comparados o início e o final do treinamento. Sugere-se que a FBM-T pode ter sido um fator influente para o aumento do recrutamento muscular no grupo Laser.
