Background: We investigated the effects of brain-computer interface (BCI) combined with mental practice (MP) and occupational therapy (OT) on performance in activities of daily living (ADL) in stroke survivors.Methods: Participants were randomized into two groups: experimental (n= 23, BCI controlling a hand exoskeleton combined with MP and OT) and control (n= 21, OT). Subjects were assessed with the functional independence measure (FIM), motor activity log (MAL), amount of use (MAL-AOM), and quality of movement (MAL-QOM). The box and blocks test (BBT) and the Jebsen hand functional test (JHFT) were used for the primary outcome of performance in ADL, while the Fugl-Meyer Assessment was used for the secondary outcome. Exoskeleton activation and the degree of motor imagery (measured as event-related desynchronization) were assessed in the experimental group. For the BCI, the EEG electrodes were placed on the regions of FC3, C3, CP3, FC4, C4, and CP4, according to the international 10–20 EEG system. The exoskeleton was placed on the affected hand. MP was based on functional tasks. OT consisted of ADL training, muscle mobilization, reaching tasks, manipulation and prehension, mirror therapy, and high-frequency therapeutic vibration. The protocol lasted 1 h, five times a week, for 2 weeks.Results: There was a difference between baseline and post-intervention analysis for the experimental group in all evaluations: FIM (p= 0.001,d= 0.56), MAL-AOM (p= 0.001,d= 0.83), MAL-QOM (p= 0.006,d= 0.84), BBT (p= 0.004,d= 0.40), and JHFT (p= 0.001,d= 0.45). Within the experimental group, post-intervention improvements were detected in the degree of motor imagery (p< 0.001) and the amount of exoskeleton activations (p< 0.001). For the control group, differences were detected for MAL-AOM (p= 0.001,d= 0.72), MAL-QOM (p= 0.013,d= 0.50), and BBT (p= 0.005,d= 0.23). Notably, the effect sizes were larger for the experimental group. No differences were detected between groups at post-intervention.Conclusion: BCI combined with MP and OT is a promising tool for promoting sensorimotor recovery of the upper limb and functional independence in subacute post-stroke survivors.

Background: In 2020, the world was surprised by the spread and mass contamination of the new Coronavirus (COVID-19). COVID-19 produces symptoms ranging from a common cold to severe symptoms that can lead to death. Several strategies have been implemented to improve the well-being of patients during their hospitalization, and virtual reality (VR) has been used. However, whether patients hospitalized for COVID-19 can benefit from this intervention remains unclear. Therefore, this study aimed to investigate whether VR contributes to the control of pain symptoms, the sensation of dyspnea, perception of well-being, anxiety, and depression in patients hospitalized with COVID-19. Methods: A randomized, double-blind clinical trial was designed. Patients underwent a single session of VR and usual care. The experimental group (n = 22) received VR content to promote relaxation, distraction, and stress relief, whereas the control group (n = 22) received non-specific VR content. Results: The experimental group reported a significant decrease in tiredness, shortness of breath, anxiety, and an increase in the feeling of well-being, whereas the control group showed improvement only in the tiredness and anxiety. Conclusions: VR is a resource that may improve the symptoms of tiredness, shortness of breath, anxiety, and depression in patients hospitalized with COVID-19. Future studies should investigate the effect of multiple VR sessions on individuals with COVID-19.

Background: Paralympic Powerlifting (PP) training tends to promote fatigue and oxidative stress. Objective: To analyze the effects of ibuprofen use on performance and oxidative stress in post-training PP athletes. Methodology: Ten national level PP athletes (age: 27.13 ± 5.57) were analyzed for oxidative stress in post-training. The study was carried out in three weeks, (1) familiarization and (2 and 3) evaluated the recovery with the use of a placebo (PLA) and ibuprofen (IBU), 800 mg. The Peak Torque (PT), Torque Development Rate (TDR), Fatigue Index (FI), reactive substances to thiobarbituric acid (TBARS) and sulfhydryl groups (SH) were evaluated. The training consisted of five sets of five repetitions (80–90%) 1-Repetition Maximum (1-RM) in the bench press. Results: The IBU showed a higher PT (24 and 48 h, p = 0.04, ɳ² p = 0.39), a lower FI (24 h, p = 0.01, ɳ²p = 0.74) and an increased lymphocyte count (p < 0.001; ɳ²p = 4.36). There was no change in oxidative stress. Conclusions: The use of IBU provided improvements in strength and did not protect against oxidative stress.

Background: Obesity is a pathology with a growing incidence in developing countries. Objective: To evaluate the evolution of cardiometabolic, anthropometrics, and physical activity parameters in individuals undergoing bariatric surgery (BS) in the public healthcare system (PUS) and private healthcare system (PHS). Methods: A longitudinal, observational, and retrospective study was conducted with 111 bariatric patients on two different health systems, with 60 patients from the PUS and 51 from the PHS. Cardiometabolic risk (CR) was analyzed by the assessment of obesity-related comorbidities (AORC) on admission and 3, 6, and 12 months after BS, and the International Physical Activity Questionnaire (IPAQ) was surveyed before and 12 months after BS. In addition, cardiometabolic risk was also assessed by biochemical (fasting glucose and complete lipidogram) and anthropometric (weight, weight loss, waist circumference, and waist-to-height ratio) parameters. Results: On admission, the parameters of severe obesity, systemic arterial hypertension (SAH), Diabetes mellitus (DM), and waiting time to BS were higher in the PUS. Additionally, in the PUS, AORC was reduced only in the SAH parameter. However, in the post-surgery moment, AORC reduced, and there was no difference between the two groups after BS. Regarding physical activity, the IPAQ showed a higher level of activity in the PHS before and one year after BS. Conclusion: At the PUS, BS is performed in patients with a higher degree of comorbidities, but BS improved the reduction of the CR at a similar level to those observed in the PHS.

Introduction. Shoulder pain as a consequence after a stroke has multifactorial causes and can prevent the functional return of the upper limb. In addition, the effectiveness of clinical protocols applied by occupational therapists remains uncertain. Objective. To identify the main treatments currently used by occupational therapists for pain in the shoulder after a stroke. Method. Articles in English published between 2015 and 2019, of the randomized clinical trial type, with populations that stroke survivors a stroke and sequelae of shoulder pain were selected. The terms and combinations used were “shoulder pain and stroke and occupational therapy,” in the electronic databases, Directory of Open Access Journals (DOAJ), Occupational Therapy Systematic Evaluation of Evidence (OTseeker), and PubMed. Statistical Review Manager (version 5.3) established the significance level $P\le 0.05$ . Results. Thirty-nine articles were found, but only four met the inclusion criteria. Electrical stimulation, therapeutic bandaging, and dry needling were eventually employed. For the meta-analysis, pain was the primary outcome, and range of motion (ROM) and upper limb function were secondary. Pain, ROM (external rotation, abduction, and flexion), and manual function were compared, and the meta-analysis showed improvement in the treatment group in clinical trials: pain (MD -2.08; 95% CI -3.23, -0.93; $P=0.0004$ ), ROM (MD 4.67; 95% CI 1.54, 7.79; $P=0.0003$ ), and manual function (MD 1.84; 95% CI 0.52, 3.16; $P=0.006$ ). Conclusion. Dry needling, California tripull taping (CTPT), and functional electrical stimulation controlled by brain-machine interface (BCI-FES) are proved effective in shoulder pain and functionality.

Background: In March 2020, the World Health Organization classified infection and contagion of coronavirus disease 2019 (COVID-19) as a worldwide pandemic. Since then, health professionals have been tirelessly researching the symptoms and consequences of this disease in people's daily lives. Occupational therapists have also been mobilized to implement effective actions in order to guarantee the functionality and quality of life of individuals and groups. The aim of this article was to investigate what available resources there are regarding occupational therapy during the pandemic, and thus support and enrich professional practice during this time. Methods: A search for was carried out for materials such as technical notes, guidelines for working with COVID-19 patients, clinical trials, and reflections and debates on occupational therapeutic practice during the COVID-19 pandemic. Articles in English, Portuguese and Spanish were included. The search was carried out in the Virtual Health Library (VHL), Google Scholar, Latin American & Caribbean Health Sciences Literature (LILACS), Scientific Electronic Library Online (SCIELO) databases, Medical Literature Analysis and Retrieval System Online (MEDLINE), Pubmed, and the websites of occupational therapy entities and organizations. Results: A total of 44 materials were found and categorised into performance guides, technical notes and scientific articles. The materials dealt with different themes, with a predominance of guidelines for hospital practices. However, there was also a significant amount of notes on the positioning of representative bodies in the preparation of intervention guides in wards, intensive care units, and outpatient and patient homes to support these professionals. Conclusions: The results demonstrate the quick response of authors in the field of occupational therapy, to combat the challenges and barriers of the COVID-19 pandemic. The texts promote scientifically-based strategies to provide the best assistance to patients during the pandemic period.
