    Abstract Objectives: This study aimed to test the effects of transcranial direct current stimulation (tDCS), using different electrode positioning and montages, on physical performance in maximum incremental tests of healthy non-athlete subjects.
    Design: A double-blinded, crossover, sham-controlled study.
    Method: Fifteen subjects (aged 25.8 ± 5 years, nine women) received one of five different tDCS protocols: (i) anodal tDCS on the primary motor cortex (M1) (a-tDCS/M1), (ii) anodal tDCS on the left temporal cortex (T3) (a-tDCS/T3), (iii) cathodal tDCS on M1 (c-tDCS/M1), (iv) cathodal on T3 (c-tDCS/T3), or (v) sham tDCS. The protocols were assigned in a random order in separate sessions. After tDCS, the volunteers performed the maximal incremental exercise test (MIT) on a cycle ergometer in each session. The following measures were used to evaluate physical performance (primary outcome) during MIT: time to exhaustion (TE), maximum power (MAX-P), and Borg Rating of Perceived Exertion (RPE) scale. In addition, as a secondary outcome measure, we assessed the lower-limb corticospinal excitability and electrical muscular activity.
    Results: tDCS applied over T3 or M1 did not influence electrical muscular activity or increase physical performance during MIT in healthy non-athlete subjects. However, our data confirmed that a-tDCS on the M1 increases lower-limb cortical excitability.
    Conclusions: Our results suggest that tDCS is not effective in improving performance during maximal dynamic exercise in non-athletes. However, we confirmed that the a-tDCS M1 protocol used in this study might increase cortical excitability in the lower limb motor cortex.

    Abstract Abstract Aims the aim of this study was to verify the effects of different intensities of locomotor exercise on corticospinal excitability. Methods 18 healthy subjects (27.6 ± 6.5 years,) participated in a design study of three different exercise protocols on a cycle ergometer: (i) 10 min at 75% Wmax (high intensity); (ii) 15min at 60% Wmax (moderate intensity) or (iii) 30 min at 45% Wmax (low intensity). The protocols of lower body cycling were assigned in random order in separate sessions. A control session was done with subjects at rest. Corticospinal excitability was assessed before (baseline) and every 5 min for 15min after the end of exercise/rest (time: 0, 5, 10 and 15) by measurement of the motor evoked potential (MEP) elicited by transcranial magnetic stimulation in the relaxed first-dorsal interosseus muscle. Results Compared to the resting session, a significant decrease (64%) in the motor evoked potential amplitudes was found only in the session of exercise of high intensity. This result seems depend on the level of physical activity of subject. No change was found after rest, low and moderate exercises. Conclusions These findings suggest that changes in the corticospinal excitability depend on exercise intensity and level of physical activity of subjects.

    Abstract Repetitive transcranial magnetic stimulation (rTMS) over motor cortex and trans-spinal direct current stimulation (tsDCS) modulate corticospinal circuits in healthy and injured subjects. However, their associated effects with physical exercise is still not defined. This study aimed to investigate the effect of three different settings of rTMS and tsDCS combined with treadmill exercise on spinal cord and cortical excitability of healthy subjects. We performed a triple blind, randomized, sham-controlled crossover study with 12 healthy volunteers who underwent single sessions of rTMS (1Hz, 20Hz and Sham) and tsDCS (anodal, cathodal and Sham) associated with 20 minutes of treadmill walking. Cortical excitability was assessed by motor evoked potential (MEP) and spinal cord excitability by the Hoffmann reflex (Hr), nociceptive flexion reflex (NFR) and homosynaptic depression (HD). All measures were assessed before, immediately, 30 and 60 minutes after the experimental procedures. Our results demonstrated that anodal tsDCS/treadmill exercise reduced MEP's amplitude and NFR's area compared to sham condition, conversely, cathodal tsDCS/treadmill exercise increased NFR's area. High-frequency rTMS increased MEP's amplitude and NFR's area compared to sham condition. Anodal tsDCS/treadmill exercise and 20Hz rTMS/treadmill exercise reduced Hr amplitude up to 30 minutes after stimulation offset and no changes were observed in HD measures. We demonstrated that tsDCS and rTMS combined with treadmill exercise modulated cortical and spinal cord excitability through different mechanisms. tsDCS modulated spinal reflexes in a polarity-dependent way acting at local spinal circuits while rTMS probably promoted changes in the presynaptic inhibition of spinal motoneurons. In addition, the association of two neuromodulatory techniques induced long-lasting changes.

    Abstract Osteoporosis and the risk of falls increase the risk of fractures and events of falls. Prescriptions and programs for different forms of exercise have different impacts on the risk of falls, and exercises from multiple categories of whole-body vibration can be effective. This study aims to evaluate the effectiveness of whole-body vibration (WBV) protocol combined with multicomponent training (MCT) in elderly women with osteoporosis and their history of falls. Our proposal is a protocol for a randomized clinical trial, divided into two stages: First, development of a protocol for WVB combined with MCT for elderly women with osteoporosis and a history of falls, under the Guidelines of the American College of Sports Medicine, and following the recommendations of the Standard Protocol Items Recommendations for Interventional Trials (SPIRIT), and second, a randomized controlled clinical trial following the Consolidated Standards of Reporting Trials (CONSORT). This trial will have implications for the effectiveness of a vibration protocol combined with multicomponent exercise on the risk of falls and quality of life for older women with osteoporosis. We expect that adding full-body vibration to an exercise protocol will decrease the risk of falls and improve participants’ quality of life, as well as their strength, balance, and functional capacity.

    Abstract 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.

    Abstract Introduction Transcranial direct current stimulation (tDCS) has been used to modify cortical excitability and promote motor learning. Objective To systematically review published data to investigate the effects of transcranial direct current stimulation on motor learning in healthy individuals. Methods Randomized or quasi-randomized studies that evaluated the tDCS effects on motor learning were included and the risk of bias was examined by Cochrane Collaboration’s tool. The following electronic databases were used: PubMed, Scopus, Web of Science, LILACS, CINAHL with no language restriction. Results It was found 160 studies; after reading the title and abstract, 17 of those were selected, but just 4 were included. All studies involved healthy, right-handed adults. All studies assessed motor learning by the Jebsen Taylor Test or by the Serial Finger Tapping Task (SFTT). Almost all studies were randomized and all were blinding for participants. Some studies presented differences at SFTT protocol. Conclusion The result is insufficient to draw conclusions if tDCS influences the motor learning. Furthermore, there was significant heterogeneity of the stimulation parameters used. Further researches are needed to investigate the parameters that are more important for motor learning improvement and measure whether the effects are long-lasting or limited in time.

    Abstract Abstract Introduction: The recovery of stroke patients is long and boring due to the repetitive nature of the exercises used and the length of treatment. Thus, we started using virtual reality as an alternative and, because of its advantages, health professionals are adapting video games for physical therapy. However, there are some limitations, such as the fact that games are designed for entertainment and not for therapeutic purposes. Objective: In order to mitigate gaps in assistive devices for physical therapy, this study describes the development and applicability of a computer support system for motor rehabilitation - Ikapp - in stroke victims. Methods: Twenty-seven stroke patients filled out a socioeconomic questionnaire, tested Ikapp during five minutes and answered a usability and satisfaction questionnaire about handling the tool. The chi-square test was used to analyze any association between sociodemographic factors and the features of the system. Results: The Ikapp system can be an excellent device to assist neurological rehabilitation of stroke patients, as participants questionnaires showed that 85.2% were satisfied in regard to motivation and inclusion of Ikapp in physiotherapy and 77.8% relative to ease of interaction with the tool. Conclusion: The Ikapp system proved to be an easy-to-use and accessible computer support system for patients with functional limitations.
