To describe the social participation frequency and the physical disability of patients who were discharged after the multidrug therapy (MDT/WHO) and factors associated with these variables. A cross-sectional and analytical study, examining associations, which took place Nova Iguaçu/Brazil. A random sample of patients treated with multidrug therapy from 1997 to 2006 was selected. The rationale for sample size was determined by the estimated proportion of physical disability in the amount of 23%, with an acceptable sampling error rate of 5%; significance level was established as 5% among the 1080 patients finally a total sample of 225 patients. The evaluations were performed from January 2010 to December 2011 and Socio-demographic and clinical data were collected from the applications completed in the national notifiable diseases information system (SINAN). In the period of interest, 2179 cases were diagnosed with leprosy; 1080 met the criteria for inclusion. Of these, 225 were randomly selected patients who had mean age 56.12 (±17.34 years), 55.6% were women, 39.9% went to high school and 28.9% were Caucasians. A total of 55.3% (125) showed multibacillary form, with a predominant dimorphous leprosy in 40.4%. Physical disability was present in 60.9% and social restrictions in 24.9% of patients. The variable physical disability was associated with the therapeutic regimen multibacillary and social participation. We observed a high frequency of disability and social restriction after long period after the start of MDT/WHO suggesting the late diagnosis of leprosy or inadequate follow-up after discharge. This study highlights the importance of systematic monitoring of these patients with their own criteria which could be held at the Family Health Strategy.

Background Most of the Brazilian population relies on public healthcare and stroke is a major cause of disability in this country of continental dimensions. There is limited information about access to rehabilitation after stroke in Brazil. Objective To provide comprehensive information about Access to Rehabilitation After discharge from public hospitals in Brazil (AReA study), up to 6 months after stroke. Methods The present study intends to collect information from 17 public health centers in 16 Brazilian cities in the 5 macroregions of the country. Each center will include 36 participants (n = 612). The inclusion criteria are: age ≥ 18 years old; ischemic or hemorrhagic stroke, from 6 months to 1 year prior to the interview; admission to a public hospital in the acute phase after stroke; any neurological impairment poststroke; patient or caregiver able to provide informed consent and answer the survey. Patients can only be recruited in public neurology or internal medicine outpatient clinics. Outcomes will be assessed by a standard questionnaire about rehabilitation referrals, the rehabilitation program (current status, duration in months, number of sessions per week) and instructions received. In addition, patients will be asked about preferences for locations of rehabilitation (hospitals, clinics, or at home). Trial Status The study is ongoing. Recruitment started on January 31^st, 2020 and is planned to continue until June 2022. Conclusion The AReA study will fill a gap in knowledge about access to stroke rehabilitation in the public health system in different Brazilian regions.

Stroke is a neurological condition that often results in long-term motor deficits. Given the high prevalence of motor impairments worldwide, there is a critical need to explore innovative neurorehabilitation strategies that aim to enhance the quality of life of patients. One promising approach involves brain–computer interface (BCI) systems controlled by electroencephalographic (EEG) signals elicited when a subject performs motor imagery (MI), which is the mental simulation of movement without actual execution. Such systems have shown potential for facilitating motor recovery by promoting neuroplastic mechanisms. Controlling BCI systems based on MI-EEG signals involves the following sequential stages: recording the raw signal, preprocessing, feature extraction and selection, and classification. Each of these stages can be executed using several techniques and numerous parameter combinations. In this study, we searched for the combination of feature extraction technique, time window, frequency range, and classifier that could provide the best classification accuracy for the BCI Competition 2008 IV 2a benchmark dataset (BCI-C), characterized by EEG-MI data of different limbs (four classes, of which three were used in this work), and the NeuroSCP EEG-MI dataset, a custom experimental protocol developed in our laboratory, consisting of EEG recordings of different movements with the same limb (three classes—right dominant arm). The mean classification accuracy for BCI-C was 76%. When the subjects were evaluated individually, the best-case classification accuracy was 94% and the worst case was 54%. For the NeuroSCP dataset, the average classification result was 53%. The individual subject’s evaluation best-case was 71% and the worst case was 35%, which is close to the chance level (33%). These results indicate that techniques commonly applied to classify different limb MI based on EEG features cannot perform well when classifying different MI tasks with the same limb. Therefore, we propose other techniques, such as EEG functional connectivity, as a feature that could be tested in future works to classify different MI tasks of the same limb.

INTRODUCTION: Despite being considered least important for clinical practice in the pyramid of evidence for recommendations, sometimes scientists' expert opinions could help to better understand the summarization of updated publications. OBJECTIVE: To provide a major summarized update about brain imaging and stimulation of the nervous system in health and disease. METHODS: Comprehensive review developed by experts in each subarea of knowledge in neuroimaging and non-invasive stimulation of the nervous system. A team of researchers and clinic experts was invited to present an update on their area of expertise. RESULTS: In basics on brain imaging techniques, we approach general and quantitative electroencephalography, functional magnetic resonance imaging, functional near-infrared spectroscopy, and experimental paradigms in brain imaging studies. Were included associations between transcranial magnetic stimulation and electromyography, electroencephalography, and functional near-infrared stimulation to evaluate brain activity. Furthermore, we showed several actualized central and peripheral neuromodulation techniques. And finally, we presented different clinical and performance uses of non-invasive neuromodulation. CONCLUSION: To our knowledge, this is a major summarized and concentrated update about brain imaging and stimulation that can benefit neuroscience researchers and clinicians from different levels of experience.

Background: Early Mobility (EM) has been recognized as a feasible and safe intervention that improves functional outcomes in hospitalized patients. The International Classification of Functioning, Disability and Health (ICF) supports understanding of functioning and disability in multidimensional concepts and efforts have been taken to apply ICF in a hospital environment. EM protocols might be linked with the ICF component of activity and participation. The correlations between ICF, EM, and functional scales might help the multidisciplinary team to conduct the best rehabilitation program, according to patients' functional demands.Objectives: The primary outcome is to analyze the activity level of neurological inpatients on admission and delivery after a Neurological Early Mobility Protocol (NEMP) at intermediate care settings in a public hospital in Brazil using Activity Level categories, HPMQ, and MBI scores. The secondary outcome is to analyze the ICF performance qualifier, specifically in the activity domain, transposing HPMQ and MBI scores to the corresponding ICF performance qualifiers.Design: An international prospective study.Methods: NEMP was used to promote patients' mobility during a hospital stay in neurological ward settings. First, patients were categorized according to their Activity Levels (ALs) to determine the NEMP phase to initiate the EM protocol. ALs also were evaluated in the first and last sessions of NEMP. Thereafter, the Hospitalized Patient Mobility Questionnaire (HPMQ) was applied to identify whether patients needed assistance during the performance of hospital activities as well as the Modified Barthel Index (MBI). Both measures were applied in NEMP admission and discharge, and the Wilcoxon Signed Rank Test was used to compare data in these two time points. HPMQ and MBI scores were re-coded in the correspondent ICF performance qualifier.Results: Fifty-two patients were included with age of 55 ± 20 (mean ± SD) years and a length of hospital stay of 33 ± 21 days. Patients were classified along ALs categories at the admission/discharge as follows: AL 0 n = 6 (12%)/n = 5 (9%); AL 1 n = 12 (23%)/n = 6 (12%); AL 2 n = 13 (25%)/n = 8 (15%); AL 3 n = 10 (19%)/n = 13 (25%); AL 4 n = 11 (21%)/n = 20 (39%). HPMQ data revealed progressions for the activities of bathing (p < 0.001), feeding (p < 0.001), sitting at the edge of the bed (p < 0.001), sit to stand transition (p < 0.001), orthostatism (p < 0.001) and walking (p < 0.001). Transposing HPMQ activities into ICF performance qualifiers, improvements were shown in bathing (d510.3 to d510.1—severe problem to mild problem) and sitting at the edge of the bed (d4153.2 to d4153.1—moderate problem to mild problem). At MBI score were observed an average of 36 [IQR−35. (95% CI 31.5; 41.1)] on NEMP admission to 52 at discharge [IQR−50 (95% CI 43.2; 60.3)] (p < 0.001). Recoding MBI scores into ICF there were improvements from severe problem (3) to moderate problem (2).Limitations: The delay in initiating NEMP compared to the period observed in the literature (24–72 h). The study was carried out at only one center.Conclusions: This study suggests that neurological inpatients, in a public hospital in Brazil had low activity levels as could be seen by MBI and HPMQ scores and in the ICF performance qualifier. However, improvements in the evaluated measures and ICF activity domain were found after NEMP. The NEMP protocol has been initiated much longer than 72 h from hospital admission, a distinct window than seen in the literature. This enlargement period could be a new perspective for hospitals that are not able to apply mobility in the earliest 24–72 h.
