Objective: To analyze the effects of photobiomodulation therapy PBMT on functional capacity and muscular performance in individuals after severe acute respiratory syndrome SARS. Methods: 15 individuals participated in the research, 7 from the active PBMT group (28.71 ± 12.91 years) and 8 individuals from the placebo PBMT group (28 ± 16.33 years) affected by COVID-19, randomly divided into two groups: placebo PBMT and active PBMT (E-Light IRL-DMC®, 288J). All volunteers underwent a final assessment using the Fatigue Assessment Scale (FAS), peak isometric strength (Lafayette Hand-Held Dynamometer™) of the knee extensors and the five-repetition sit-to-stand test (STS). Then, active or placebo PBMT was applied to six quadriceps sites of the dominant leg. Results: after the protocol the active PBMT for mean peak force obtained (34.31 ± 13.50) and the placebo PBMT group (31.11 ± 7.82) and in the TSLC5 active PBMT group 9.19 ± 1.75) and the placebo PBMT (9.18 ± 2.09), both with no significant difference in increased functional capacity and muscular performance between the groups. Conclusion: PBMT had no effect when compared to placebo in improving functional capacity and muscle performance in post- SARS individuals. Studies with greater sample size are suggested, with the aim of verifying the causal relationship between PBMT and the musculoskeletal repercussions after SARS.

The sequelae of coronavirus disease-2019 (COVID-19) are another socio-economic problem of the pandemic. Fatigue and dyspnea are the most prevalent symptoms. It is not known whether exercise can be used to treat long COVID-19. This study aimed to investigate the effects of an 8-week face-to-face rehabilitation program on COVID-19 compared to a remote monitoring group. A total of 37 participants (24.3% hospitalized) were assessed before and after rehabilitation (n=22; 40.8±10.0 years) or remote monitoring (n=15; 45.4±10.5 years). The participants were allocated according to their preferences. Both groups showed improved fatigue and exercise capacity (Incremental Shuttle Walk Test). Participants in the face-to-face rehabilitation group showed improved dyspnea (Pulmonary Functional Status and Dyspnea Questionnaire), anxiety (Hospital Anxiety and Depression Scale), attention, and short-term memory (d2-R and Rey’s Auditory-Verbal Learning Test). Of the main sequelae, fatigue improves naturally, whereas dyspnea requires rehabilitation. Our results demonstrated the benefits of exercise for COVID-19 sequelae.

Highlights The present study demonstrated that PBM was effective in minimizing pain and edema in the acute inflammatory process in an experimental model. The 830 nm wavelength (5.88 J energy) was more effective in improving edema in the acute inflammatory process in an experimental model. In pain analysis, the energy of 2.94 J was more effective regardless of the wavelength used in the acute inflammatory process in an experimental model.

Report the effects of photobiomodulation (PBM) and therapeutic ultrasound (TUS) on the viability of TRAM in mice. Materials and Methods: Fifty-five mice Swiss were subjected to treatment for 5 days. Group 1, treatment was performed with the agents switched off. Groups 2 to 5 were treated with different wavelengths 660 and 830 nanometers (nm) and groups 6 to 11 with TUS of 1 and 3 MHz frequency. Macrometric analyses were performed using a specific camera and analyzed by the ImageJ® software. Thermographic analyses were performed with the Flir C2 and analyzed using the FLIR Tools software. Results: Group 9 obtained 95% of viable area on the 3rd day and 85% on the 5th day, showing the effectiveness of the TUS in the flap viability. Regarding skin temperature, there was a difference only in the immediate postoperative period in group 1, which had a lower temperature than the other groups. Conclusions: TUS demonstrated greater efficiency in maintaining the viability of TRAM. PBM 830 nm also demonstrated good results in the viability of TRAM.

Background: Ergogenic evidence for caffeine is robust in sports and isolated limb tasks. Our objective was to evaluate a possible ergogenic effect on postural muscles, still unknown, through the Biering-Sørensen’s lumbar extension test. Methods: A double-blind, controlled placebo, crossover study. Fifty-one healthy, physically inactive male subjects (18-25 years) with average body mass (BMI 18.5 – 24.9 kg/m ² ) were recruited. The subjects received oral caffeine (6 mg/kg) and saline (0.3%) in two cross-evaluations separated by one week. The primary outcome was the time in the Biering-Sørensen test after 1 hour of treatment. The secondary outcomes were peak lumbar extension force, rating of perceived exertion, EMG’s median frequency and muscle recruitment of multifidus spinae and transversalis /interne oblique muscles, and cardiovascular variables (heart rate and blood pressure). Results: 27 subjects were blindly treated with caffeine and saline. Caffeine was ergogenic during the Biering-Sørensen test. It increased lumbar extension time ( d = 0.34, Pd = 0.37, P η ² = 0.49, Pmultifidus spinae . In the transversalis/interne oblique muscles, caffeine increased the median frequency η ² = 0.13, P η ² = 0.13, P<0.05) Tachycardia and increased blood pressure at the lumbar test were higher in the caffeine condition (P< 0.05). Conclusions: Our results show that caffeine is ergogenic for postural muscles. Decreased RPE and improved muscle activity suggest central mechanisms of caffeine. Trial registration: UTN U1111-1234-2079. BULLET POINTS: Caffeine increases the extension time of the lumbar spine in the Biering-Sørensen test. Caffeine decreases perceived exertion during the Biering-Sørensen test. Caffeine increases muscle stimulation and recruitment of the multifidus spinae during the Biering-Sørensen test. Caffeine increases muscle stimulation of the transversalis/interne oblique muscles during the Biering-Sørensen test.

O principal objetivo desta pesquisa é o desenvolvimento de um modelo de tecnologia que permita o monitoramento da coluna vertebral, registrando movimentos nos pacientes afetados pelo tratamento auxiliar da lombalgia. Assim, um modelo de tecnologia vestível com sensores que monitoram os movimentos da coluna vertebral e registra os dados no aplicativo para smartphone foi desenvolvido nesta pesquisa para uso posterior por profissionais de saúde. O protótipo foi avaliado por meio de uma amostra de 33 voluntários, observando uma funcionalidade do produto, uma avaliação clínica da coluna vertebral, uma identificação de hábitos comportamentais na caracterização da amostra.A viabilidade das tecnologias embarcadas computacionais em produtos de vestuário é evidenciada por esta pesquisa como um campo de estudo em uso, facilitando a coleta de dados do usuário no dia a dia.
