Primary Motor Area Activity in Phantom Limb Imagery of Traumatic Unilateral Lower Limb Amputees With Phantom Limb Pain.

Introduction: Estimates of the worldwide increase in amputees raises the awareness to solve long-standing problems. Understanding the functional brain modifications after a lower limb amputation (LLA) is one of the first steps towards proposing new rehabilitation approaches. Functional modifications in the central nervous system due the amputation could be involved in prosthesis use failures and Phantom Limb Pain (PLP), increasing costs and overwhelming the health services. Objective: This study analyses orphan primary motor area (M1-Orphan) hemodynamic and metabolic behaviour, which previously controlled the limb that was amputated, in comparison with the M1-Preserved, responsible for the intact limb (IL) during phantom limb imagery moving during Mirror Therapy (MT), compared to Isolated Intact Limb Movement Task (I-ILMT). Methodology: A case-control study with unilateral traumatic LLA with moderate PLP who measured [oxy-Hb] and [deoxy-Hb] in the M1 area by Functional Near InfraredSpectroscopy (fNIRS) during the real (I-ILMT) and MT task. Results: Sixty-five patients, with 67.69% of men, young (40.32 ± 12.91), 65.63% amputated due motorcycle accidents, 4.71 ± 7.38 years ago, predominantly above the knee (57.14%). The M1 activation in the orphan cortex did not differ from the activation in the intact cortex during MT (P > .05). Conclusion: The perception of the Phantom limb moving or intact limb moving is metabolically equivalent in M1, even in the absence of a limb. In other words, the amputation does not alter the brain metabolism in control of phantom movement.

Non-invasive sound wave brain stimulation with Transcranial Pulse Stimulation (TPS) improves neuropsychiatric symptoms in Alzheimer's disease.

BACKGROUND: This study explores Transcranial Pulse Stimulation (TPS) as a potential non-invasive treatment for Alzheimer's disease (AD), focusing on its impact on cognitive functions and behavioral symptoms. METHODS: In a prospective, one-arm open-label trial, ten patients with mild to moderate dementia due to AD were assessed using the Alzheimer's Disease Assessment Scale (ADAS-Cog), Neuropsychiatric Inventory (NPI), Pfeffer Functional Activities Questionnaire, and Zarit Caregiver Burden Interview. Assessments occurred at 30- and 90-days post-treatment. The TPS protocol consisted of 10 sessions over five weeks, using the Neurolith® device to deliver 6000 focused shockwave pulses at 0.25 mJ/mm2 and a frequency of 4 Hz. RESULTS: TPS significantly reduced neuropsychiatric symptoms, with NPI scores decreasing by 23.9 points (95% CI: -39.19 to -8.61, p = 0.0042) after 30 days, and by 18.9 points (95% CI: -33.49 to -2.91, p = 0.022) after 90 days. These changes had large effect sizes (Cohen's dz = 1.43 and dz = 0.94, respectively). A decreasing trend was observed in the ADAS-Cog score (-3.6, 95% CI: -7.18 to 0.00, p = 0.05) after 90 days, indicating a potential reduction in cognitive impairment, though not statistically significant. CONCLUSION: The preliminary results indicate that TPS treatment leads to significant improvement in neuropsychiatric symptoms in AD patients, showing promise as a therapeutic approach for AD. Further research is needed to fully establish its effectiveness, especially concerning cognitive functions.

Data-driven, cross-disciplinary collaboration: lessons learned at the largest academic health center in Latin America during the COVID-19 pandemic.

Introduction: The COVID-19 pandemic has prompted global research efforts to reduce infection impact, highlighting the potential of cross-disciplinary collaboration to enhance research quality and efficiency. Methods: At the FMUSP-HC academic health system, we implemented innovative flow management routines for collecting, organizing and analyzing demographic data, COVID-related data and biological materials from over 4,500 patients with confirmed SARS-CoV-2 infection hospitalized from 2020 to 2022. This strategy was mainly planned in three areas: organizing a database with data from the hospitalizations; setting-up a multidisciplinary taskforce to conduct follow-up assessments after discharge; and organizing a biobank. Additionally, a COVID-19 curated collection was created within the institutional digital library of academic papers to map the research output. Results: Over the course of the experience, the possible benefits and challenges of this type of research support approach were identified and discussed, leading to a set of recommended strategies to enhance collaboration within the research institution. Demographic and clinical data from COVID-19 hospitalizations were compiled in a database including adults and a minority of children and adolescents with laboratory confirmed COVID-19, covering 2020-2022, with approximately 350 fields per patient. To date, this database has been used in 16 published studies. Additionally, we assessed 700 adults 6 to 11 months after hospitalization through comprehensive, multidisciplinary in-person evaluations; this database, comprising around 2000 fields per subject, was used in 15 publications. Furthermore, thousands of blood samples collected during the acute phase and follow-up assessments remain stored for future investigations. To date, more than 3,700 aliquots have been used in ongoing research investigating various aspects of COVID-19. Lastly, the mapping of the overall research output revealed that between 2020 and 2022 our academic system produced 1,394 scientific articles on COVID-19. Discussion: Research is a crucial component of an effective epidemic response, and the preparation process should include a well-defined plan for organizing and sharing resources. The initiatives described in the present paper were successful in our aim to foster large-scale research in our institution. Although a single model may not be appropriate for all contexts, cross-disciplinary collaboration and open data sharing should make health research systems more efficient to generate the best evidence.

Distinct patterns of metabolic motor cortex activity for phantom and residual limb pain in people with amputations: A functional near-infrared spectroscopy study.

BACKGROUND: Phantom pain limb (PLP) has gained more attention due to the large number of people with amputations around the world and growing knowledge of the pain process, although its mechanisms are not completely understood. OBJECTIVES: The aim of this study was to understand, in patients with amputations, the association between PLP and residual limb pain (RLP), and the brain metabolic response in cortical motor circuits, using functional near-infrared spectroscopy (fNIRS). METHODS: Sixty participants were recruited from the rehabilitation program in São Paulo, Brazil. Included patients were aged over 18 years, with traumatic unilateral lower-limb amputation, with PLP for at least 3 months after full recovery from amputation surgery. PLP and RLP levels were measured using visual analogue scales. fNIRS was performed during motor execution and motor mirror tasks for 20 s. In order to highlight possible variables related to variation in pain measures, univariate linear regression analyses were performed for both experimental conditions, resulting in four fNIRS variables (two hemispheres x two experimental conditions). Later, in order to test the topographic specificity of the models, eight multivariate regression analyses were performed (two pain scales x two experimental conditions x two hemispheres), including the primary motor cortex (PMC) related channel as an independent variable as well as five other channels related to the premotor area, supplementary area, and somatosensory cortex. All models were controlled for age, sex, ethnicity, and education. RESULTS: We found that: i) there is an asymmetric metabolic activation during motor execution and mirror task between hemispheres (with a predominance that is ipsilateral to the amputated limb), ii) increased metabolic response in the PMC ipsilateral to the amputation is associated with increased PLP (during both experimental tasks), while increased metabolic response in the contralateral PMC is associated with increased RLP (during the mirror motor task only); ii) increased metabolic activity of the ipsilateral premotor region is associated with increased PLP during the motor mirror task; iii) RLP was only associated with higher metabolic activity in the contralateral PMC and lower metabolic activity in the ipsilateral inferior frontal region during motor mirror task, but PLP was associated with higher metabolic activity during both tasks. CONCLUSION: These results suggest there is both task and region specificity for the association between the brain metabolic response and the two different types of post-amputation pain. The metabolic predominance that is ipsilateral to the amputated limb during both tasks was associated with higher levels of PLP, suggesting a cortical motor network activity imbalance due to potential interhemispheric compensatory mechanisms. The present work contributes to the understanding of the underlying topographical patterns in the motor-related circuits associated with pain after amputations.

Parâmetros de referência espaço-temporais de um sensor inercial para sujeitos brasileiros sadios / Spatial-temporal gait parameters based on a wearable inertial sensor of healthy Brazilian subjects

Gait analysis in a laboratory may be expensive, time-consuming, and restricted to a controlled environment. Validated wearable technology may be an alternative to such analysis. However, wearable technologies should demonstrate reference values of a healthy population. Objective: To establish spatio-temporal gait reference values of an accelerometer (G-Walk) in a healthy Brazilian population. Methods: This is a cross-sectional study with 124 healthy subjects evaluated with G-Walk in the 6-minute and 10-meter walk tests (6MWT and 10MWT). Gait parameters of Velocity, Cadence, Distance, and gait symmetry variables were retrieved for analysis. Clinical and demographical characteristics were also collected and tested with simple linear regression as covariables of the gait characteristics. The bootstrapped 5th percentile of the gait parameter established the reference values. If a covariable influence was found, the reference values were established by subgroup analysis according to the covariable. Results: The study analyzed 114 subjects, mostly women (67.74%), aged 39.36 (SD 12.18). Height was a covariable of cadence for the 10MWT and cadence and stride length for the 6MWT. Age and sex combined were covariables of 6MWT velocity, and sex alone was a covariable of 6MWT. All reference values for symmetry were above 89%, velocity at the 10MWT was above 1.0m/s, and distance at the 6MWT was 354m and 359.5 for females and males, respectively. Conclusions: Our study generated reference values for spatio-temporal gait analysis with G-Walk of a population of a major urban area, considering the covariables of age, height, and sex.

Análises da marcha em laboratório tem custo elevado, demandando tempo e ambiente controlado. Wearables são equipamentos portáteis que podem ser alternativas aos laboratórios. Valores de referência podem determinar parâmetros para análises de marcha de pessoas com patologias. Objetivo: Estabelecer valores de referência espaço-temporais de um acelerômetro (G-Walk) em uma população saudável. Métodos: Trata-se de um estudo transversal com indivíduos saudáveis avaliados com G-Walk nos testes de caminhada de 6 minutos e de 10 metros (TC6 e TC10). Velocidade, cadência, distância e de simetria da marcha foram analisados. Características clínicas e demográficas também foram testadas com regressão linear simples como covariáveis das características da marcha. Os valores de referência foram estabelecidos pelo quinto percentil dos parâmetros por bootstrap e na presença de covariáveis demográficas, os valores foram estabelecidos por análise de subgrupos, de acordo com a covariável. Resultados: O estudo analisou 114 sujeitos, em sua maioria mulheres (67,74%), com idade de 39,36 (DP 12,18). A altura foi uma covariável da cadência do TC10 e da cadência e comprimento da passada do TC6. Idade e sexo combinados foram covariáveis da velocidade do TC6, e o sexo foi uma covariável do TC6. Todos os valores de referência para simetria foram superiores a 89%, a velocidade no TC10 foi superior a 1,0m/s e a distância no TC6 foi de 354m e 359,5m para mulheres e homens, respectivamente. Conclusões: Nosso estudo gerou valores de referência para análise espaço-temporal da marcha com o equipamento G-Walk em uma população de uma grande área urbana, considerando as covariáveis idade, altura e sexo.

Combinação de terapia por ondas de choque extracorpórea e agulhamento seco no tratamento de lombalgia crônica incapacitante: um relato de caso / Combination of extracorporeal shockwave therapy and dry needling as treatment of disabling chronic low back pain: a case report

Paciente do sexo masculino, 55 anos, apresentava antecedente clínico de radiculopatia lombar abordado cirurgicamente (discectomia e artrodese L5-S1) em dezembro de 2021, com resolução completa da dor associada. Iniciou com quadro de dor pós-operatória de características distintas. A primeira sessão de tratamento iniciou-se com terapia por ondas de choque extracorpóreas focal direcionada ao quadrado lombar, glúteo médio, glúteo mínimo e região peritrocantérica à direita. Posteriormente, associou-se agulhamento seco em pontos-gatilho presentes nesses mesmos 3 músculos e também no ligamento sacrotuberal direito, junto à inserção do glúteo máximo direito. Numa reavaliação uma semana depois, o paciente referiu uma redução de 70% da intensidade da dor inicial. O mesmo tratamento foi repetido, com resolução completa dos sintomas no final da sessão. Três meses depois, o doente manteve o controle álgico e recuperou totalmente a sua funcionalidade e qualidade de vida anteriores. Neste caso de limitação funcional a longo prazo devido a dor lombar crônica, a combinação da terapia por ondas de choque extracorporais e do agulhamento seco resultou num método eficaz e rápido para obter o alívio da dor e restaurar a funcionalidade anterior. No entanto, são necessários mais estudos para investigar o impacto desta combinação de terapias no controle da dor e na perda de funcionalidade devido à dor lombar crônica.

Male patient, 55 years old, had a clinical background of lumbar radiculopathy and a surgical approach (L5-S1 discectomy and arthrodesis) in December of 2021, with complete resolution of associated pain. One year later, the patient seeks medical treatment, referring a new, different pattern of low back pain, which initiated post-surgery. The first treatment session began with focused extracorporeal shockwave therapy directed at the right quadratus lumborum, gluteus medius, gluteus minimus and peritrochanteric region. Afterwards, dry needling was associated in trigger-points present in those same 3 muscles and also in the right sacrotuberal ligament, close to the insertion of the right gluteus maximus. In a reevaluation one week later, the patient reported a reduction of 70% of initial pain intensity. The same treatment was repeated, with complete resolution of symptoms at the end of the session. Three months later, the patient-maintained symptom control and fully recovered his previous functionality and quality of life. In this case of long-term functional limitation due to chronic low back pain, the combination of extracorporeal shock wave therapy and dry needling resulted in an effective and quick method to achieve pain relief and restore previous functionality. However, more studies are needed to investigate the impact of this combination of therapies in pain management and functionality loss due to chronic low back pain.

Neurophysiological biomarkers of motor improvement from Constraint-Induced Movement Therapy and Robot-Assisted Therapy in participants with stroke.

Background: The mechanism of stroke recovery is related to the reorganization of cerebral activity that can be enhanced by rehabilitation therapy. Two well established treatments are Robot-Assisted Therapy (RT) and Constraint-Induced Movement Therapy (CIMT), however, it is unknown whether there is a difference in the neuroplastic changes induced by these therapies, and if the modifications are related to motor improvement. Therefore, this study aims to identify neurophysiological biomarkers related to motor improvement of participants with chronic stroke that received RT or CIMT, and to test whether there is a difference in neuronal changes induced by these two therapies. Methods: This study included participants with chronic stroke that took part in a pilot experiment to compare CIMT vs. RT. Neurophysiological evaluations were performed with electroencephalography (EEG) and transcranial magnetic stimulation (TMS), pre and post rehabilitation therapy. Motor function was measured by the Wolf Motor Function Test (WMFT) and Fugl-Meyer Assessment Upper Limb (FMA-UL). Results: Twenty-seven participants with chronic stroke completed the present study [mean age of 58.8 years (SD ± 13.6), mean time since stroke of 18.2 months (SD ± 9.6)]. We found that changes in motor threshold (MT) and motor evoked potential (MEP) in the lesioned hemisphere have a positive and negative correlation with WMFT improvement, respectively. The absolute change in alpha peak in the unlesioned hemisphere and the absolute change of the alpha ratio (unlesioned/lesioned hemisphere) is negatively correlated with WMFT improvement. The decrease of EEG power ratio (increase in the lesioned hemisphere and decrease in the unlesioned hemisphere) for high alpha bandwidths is correlated with better improvement in WMFT. The variable "type of treatment (RT or CIMT)" was not significant in the models. Conclusion: Our results suggest that distinct treatments (RT and CIMT) have similar neuroplastic mechanisms of recovery. Moreover, motor improvements in participants with chronic stroke are related to decreases of cortical excitability in the lesioned hemisphere measured with TMS. Furthermore, the balance of both EEG power and EEG alpha peak frequency in the lesioned hemisphere is related to motor improvement.

Digital Platform for Continuous Monitoring of Patients Using a Smartwatch: Longitudinal Prospective Cohort Study.

BACKGROUND: Since the COVID-19 pandemic, there has been a boost in the digital transformation of the human society, where wearable devices such as a smartwatch can already measure vital signs in a continuous and naturalistic way; however, the security and privacy of personal data is a challenge to expanding the use of these data by health professionals in clinical follow-up for decision-making. Similar to the European General Data Protection Regulation, in Brazil, the Lei Geral de Proteção de Dados established rules and guidelines for the processing of personal data, including those used for patient care, such as those captured by smartwatches. Thus, in any telemonitoring scenario, there is a need to comply with rules and regulations, making this issue a challenge to overcome. OBJECTIVE: This study aimed to build a digital solution model for capturing data from wearable devices and making them available in a safe and agile manner for clinical and research use, following current laws. METHODS: A functional model was built following the Brazilian Lei Geral de Proteção de Dados (2018), where data captured by smartwatches can be transmitted anonymously over the Internet of Things and be identified later within the hospital. A total of 80 volunteers were selected for a 24-week follow-up clinical trial divided into 2 groups, one group with a previous diagnosis of COVID-19 and a control group without a previous diagnosis of COVID-19, to measure the synchronization rate of the platform with the devices and the accuracy and precision of the smartwatch in out-of-hospital conditions to simulate remote monitoring at home. RESULTS: In a 35-week clinical trial, >11.2 million records were collected with no system downtime; 66% of continuous beats per minute were synchronized within 24 hours (79% within 2 days and 91% within a week). In the limit of agreement analysis, the mean differences in oxygen saturation, diastolic blood pressure, systolic blood pressure, and heart rate were -1.280% (SD 5.679%), -1.399 (SD 19.112) mm Hg, -1.536 (SD 24.244) mm Hg, and 0.566 (SD 3.114) beats per minute, respectively. Furthermore, there was no difference in the 2 study groups in terms of data analysis (neither using the smartwatch nor the gold-standard devices), but it is worth mentioning that all volunteers in the COVID-19 group were already cured of the infection and were highly functional in their daily work life. CONCLUSIONS: On the basis of the results obtained, considering the validation conditions of accuracy and precision and simulating an extrahospital use environment, the functional model built in this study is capable of capturing data from the smartwatch and anonymously providing it to health care services, where they can be treated according to the legislation and be used to support clinical decisions during remote monitoring.

Associação de estimulação por ondas de choque a toxina botulínica e baclofeno durante a reabilitação de paciente com lesão medular e trauma cranioencefálico: relato de caso / Association of extracorporeal shockwave stimulation to botulinum toxin and baclofen during an in-patient rehabilitation in spinal cord injury and traumatic brain injury: case report

Recentemente, a terapia por ondas de choque extracorpóreas (TOCE) mostraram-se ser uma promissora tecnologia não invasiva para neuromodulação e recuperação funcional devido a melhora em brotamento neuronal, neuroproteção, controle de neuroplasticidade e reorganização neuronal, além de atuar em fatores de neurogênese. Objetivo: Descrever um caso que usa TOCE como um adjuvante na reabilitação de trauma medular. Relato de caso: LPS, 25 anos, estudante de medicina, sofreu uma queda de altura indeterminada com fratura de C5 e lesão medular associada a trauma cranioencefálico. Na fase aguda, ele se recuperou adequadamente, tendo sido submetido a descompressão e fixação de coluna e hospitalizado por 5 meses devido a disautonomias e infecções urinárias. Após esse período, ele iniciou um programa de reabilitação intensiva para tetraplegia espástica com classificação inicial segundo o ASIA (American Spinal Injury Association) nível C5 motor e C6 sensório. O tratamento incluiu 10 sessões de TOCE, realizadas com Duolith SD1 (Storz Medical, Suíça) com uma densidade de energia de 0,25mJ/mm², 5 cm e 3 cm de profundidade de foco, 2000 pulsos aplicados na linha média de coluna níveis C5 a T1 e 2000 pulsos a 5 cm de profundidade aplicados em região plantar bilateral. Bloqueio com toxina botulínica e fenol foram realizados com resposta parcial apesar da dose otimizada de baclofeno.

Recently, extracorporeal shockwaves (ESWT) have shown as a promising non-invasive technology for neuromodulation and functional recovery, due to improving neuronal budding, neuroprotection, control of neuroplasticity and neuronal reorganization, in addition to acting on neurogenesis factors. Objective: To describe a case that uses ESWT as an adjuvant to the rehabilitation of spinal cord trauma. Case Report: LPS, 25 years old, medical student, suffered a fall from an undetermined height with C5 fracture and spinal cord injury, associated with a cranioencephalic trauma. In the acute phase, he was rescued properly, performed decompression and spinal cord fixation and remained hospitalized for 5 months due to dysautonomia and urinary infections. After this period, he started an intensive in-patient rehabilitation program for spastic tetraplegia with initial classification according to ASIA C5 (motor) and C6 (sensory). The treatment included 10 sessions of ESWT, made with Duolith SD1 (Storz Medical, Switzerland) with an Energy flux density 0,25 mJ/mm2, at 5cm and 3cm depth focus, 2000 pulses each over the spinal cord at the midline of levels from C5 to T1, and 2000 pulses at 5cm depth focus applied at plantar region bilaterally.

Health System's Role in Facilitating Health Service Access among Persons with Spinal Cord Injury across 22 Countries.

(1) Background: Despite efforts to improve access to health services, between- and within-country access inequalities remain, especially for individuals with complex disabling conditions like spinal cord injury (SCI). Persons with SCI require regular multidisciplinary follow-up care yet experience more access barriers than the general population. This study examines health system characteristics associated with access among persons with SCI across 22 countries. (2) Methods: Study data are from the International Spinal Cord Injury Survey with 12,588 participants with SCI across 22 countries. Cluster analysis was used to identify service access clusters based on reported access restrictions. The association between service access and health system characteristics (health workforce, infrastructure density, health expenditure) was determined by means of classification and regression trees. (3) Results: Unmet needs were reported by 17% of participants: lowest (10%) in Japan, Spain, and Switzerland (cluster 1) and highest (62%) in Morocco (cluster 8). The country of residence was the most important factor in facilitating access. Those reporting access restrictions were more likely to live in Morocco, to be in the lowest income decile, with multiple comorbidities (Secondary Conditions Scale (SCI-SCS) score > 29) and low functioning status (Spinal Cord Independence Measure score < 53). Those less likely to report access restriction tended to reside in all other countries except Brazil, China, Malaysia, Morocco, Poland, South Africa, and South Korea and have fewer comorbidities (SCI-SCS < 23). (4) Conclusions: The country of residence was the most important factor in facilitating health service access. Following the country of residence, higher income and better health were the most important facilitators of service access. Health service availability and affordability were reported as the most frequent health access barriers.

Robotic-Assisted Gait Training (RAGT) in Stroke Rehabilitation: A Pilot Study.

Objective: To compare the effects of 2 types of robotic-assisted gait training (RAGT) devices that have been used in stroke rehabilitation. Design: Retrospective cohort. Setting: Rehabilitation hospital. Participants: 24 community dwelling people with stroke (N=24). Interventions: RAGT with either an exoskeleton (Lokomat) (mean age=53.8 years; 30% men; mean duration of stroke =17.8 months) or an end-effector (G-EO) (mean age=50.5 years; 77.8% men; mean duration of stroke =13.11) delivered 3 times per week (36 sessions total). Main Outcome Measures: The following tests/scales were employed before and after RAGT: Functional Ambulation Categories (FACs), timed Up and Go (TUG), 10-Meter Walk Test (10MWT), 6-Minute Walk Test (6MWT), Trunk Impairment Scale, Dynamic Gait Index (DGI), Berg Balance Scale (BBS), and ability to climb stairs (time to climb 6 steps of 15 cm each; ability to climb stairs). Results: There were 5 dropouts, all from the G-EO group. At the end, 10 participants in the Lokomat and 9 in the G-EO group completed the intervention. From pre- to post-RAGT, G-EO patients improved on all functional tests/scales, whereas Lokomat patients improved only on the TUG, DGI, and BBS. Most patients showed improvements above the relative smallest real difference in the TUG, 10MWT, and 6MWT. Conclusions: Both end-effectors and exoskeletons may improve clinically relevant aspects of walking function. However, this study had a small sample, was retrospective, non-randomized, and had a significant number of drop-outs, therefore its findings should be interpreted carefully. Future studies are needed for investigating potential differences in clinical results, side effects, contraindications, and cost effectiveness between these 2 different types of RAGT.

Estimulação cerebral por pulsos sonoros de baixa frequência como coadjuvante nas alterações das funções corticais superiores / Non-invasive brain stimulation by low-frequency sound pulses as an adjunct to changes in higher cortical functions

Não há dúvidas sobre os prejuízos na vida humana, extensivos à família e sociedade como um todo, abrangendo todos os aspectos funcionais das pessoas envolvidas, além do indivíduo, originados dos traumatismos cranioencefálico, agudos e crônicos, externos ou internos: acidentes, atropelamentos, quedas, crimes, acidente vascular cerebral, doenças com neurodegeneração progressiva, resultando em estados demenciais. Ao longo de meio século, houve a introdução contínua de medicamentos, com resultados usualmente contraditórios e frustrantes, exigindo novas tentativas com outras classes farmacológicas. No todo, a limitação se faz sentir na impossibilidade de reversão ou mesmo de mera estabilização dos danos neurológicos, e inocuidade em termos de estimulação da neuroplasticidade. Uma exceção parece ser uma nova abordagem: a estimulação cerebral profunda por pulsos sonoros de baixa frequência (Transcranial Pulse Stimulation, ou TPS). Ainda pouco conhecida, a não ser em alguns centros de tratamento, tem se mostrado ser um acréscimo válido, por complementar os programas multidisciplinares de reabilitação

There is no doubt about the damage to human life, also extended to family and society as a whole, regarding all the functional aspects of those involved, not only the patient itself, which originates from traumatic brain injury, acute or chronic, for external or internal reasons, such as accidents, run overs, falls, crimes, stroke, progressive neurodegenerative diseases that result in dementia states. Over half a century, drugs have been continuously introduced, however their results have constantly been contradictory and frustrating, requiring new attempts with other pharmacological classes. Overall, the limitation is felt in the impossibility of reversing or even merely stabilizing the neurological damage and inefficacy regarding neuroplasticity stimulation. One exception seems to be a new approach, the non-invasive brain stimulation by low-frequency sound pulses (Transcranial Pulse Stimulation, or TPS). Except for some treatment centers, TPS is still unknown, however it has shown to be a valid adjunct in multidisciplinary rehabilitation programs

Validity study of a triaxial accelerometer for measuring energy expenditure in stroke inpatients of a physical medicine and rehabilitation center.

PURPOSE: Establish the validity of a triaxial accelerometer (Dynaport®) for evaluating the energy expenditure of patients with stroke sequelae at a rehabilitation hospital. METHODS: This is a cross-sectional study with 24 stroke inpatients of a rehabilitation hospital. The participants were assessed on energy expenditure by an ergospirometer system and the triaxial accelerometer simultaneously during a walk test. The data collected by both devices were compared by intraclass correlation coefficient (ICC) and Bland-Altman limits of agreement. RESULTS: An almost perfect agreement (ICC = 0,94) in the energy expenditure measured by the accelerometer compared to the results of the ergospirometer system was found during the exercise test. The Bland-Altman analysis has shown suitable limits of agreement. Post hoc analyses with the maximum volume of oxygen and the total energy expenditure measured by the ergospirometer system evidenced significant correlation with the energy expenditure measurements by the accelerometer. CONCLUSION: Our results evidence that the triaxial accelerometer Dynaport® and its built-in software are valid for estimating the energy expenditure of stroke sequelae during a walk exercise.

Establishing a Cancer Rehabilitation Service in a Middle-Income Country: an Experience from Brazil.

Purpose of Review: Our aim is to provide a historical review of the implementation of a cancer rehabilitation center in Brazil, active since 2008. We expect this data to support the implementation of other centers both in Brazil and worldwide. Recent Findings: Cancer rehabilitation delivery is fragmented and punctuated in most cases, and cancer rehabilitation centers are rare. Data on how to establish rehabilitation centers could facilitate the implementation of new centers. We provide data on what was our strategy for hiring, establishing treatment protocols, barriers, and facilitators. We also provide figures on the number of each rehabilitation specialist, as well as the general standard operating procedures of our rehabilitation center, among other features. Summary: Establishing cancer rehabilitation centers in a middle-income country is feasible. We expect that our experience may facilitate the establishment of new cancer rehabilitation services and the improvement of current ones.

Gamification in Musculoskeletal Rehabilitation.

PURPOSE OF REVIEW: This study is a narrative review aiming at evaluating the current literature of the last 5 years on gamification and musculoskeletal rehabilitation. The article search involved the following MeSH terms at PubMed: "gamification," "exergaming," and "rehabilitation." Original studies in English language were included. RECENT FINDINGS: After careful analysis of the search results, 17 articles were included in this review. The use of games for rehabilitation was investigated in musculoskeletal rehabilitation conditions such as shoulder surgery, impingement syndrome, rheumatoid arthritis, osteoarthritis, low back pain, fibromyalgia, fracture, and ligament reconstruction. Results were similar or superior to conventional physical therapy or home-based exercises, with the additional benefit of improving motivation to the exercise program. Improvements in quality of life and perceived health status were also observed. The cost-effectiveness of this type of technology was also mentioned as an advantage of exergames in musculoskeletal rehabilitation. Studies involving gamification in musculoskeletal rehabilitation stress the potential of this resource in several aspects of physical fitness, health, and quality of life, also improving motivation and adherence to the exercise treatment.

Results from the International Spinal Cord Injury Community Survey: The Lived Experience of People with Spinal Cord Injury in South-Eastern Brazil.

OBJECTIVE: The incidence of spinal cord injury in Brazil is increasing. It is important to understand more about how individuals are living with spinal cord injury. DESIGN: Cross-sectional, observational study of individuals with spinal cord injury in south-eastern Brazil. SUBJECTS: A questionnaire with 125 questions was applied to individuals diagnosed with spinal cord injury. Participants were recruited by survey team from 2 rehabilitation centres (both in south-eastern Brazil) that treat persons diagnosed with SCI. Personal characteristics, associated health conditions, quality of life, work status, environmental factors, and other functioning-related aspects were evaluated. RESULTS: A total of 201 individuals participated in the survey. Of these, 79% were male, mean age 44 years, 60% were considered paraplegic, and the major causes of impairment were firearm injuries and road traffic accidents. Spasticity was the most frequently reported health condition, followed by neuropathic pain. 50% of subjects did not report any difficulty with participation in activities of daily living. However, only approximately 10% of subjects returned to work after spinal trauma. Their quality of life is reported 44% as good. CONCLUSION: Most people with spinal cord injury in south-eastern Brazil are male and paraplegic, health problems and spasticity is considered their most problematic health condition. Although they report having a good quality of life, they still encounter disabling environmental barriers that make their life more difficult, such as poor accessibility of public spaces, and only a small proportion (10%) returned to work after their injury. This study provides an initial overview of the lived experience of people with spinal cord injury in south-eastern Brazil and should serve as a starting point for future research on this population.

Digital Platform to Continuously Monitor Patients Using a Smartwatch: Preliminary Report.

BACKGROUND: Monitoring vital signs such as oximetry, blood pressure, and heart rate is important to follow the evolution of patients. Smartwatches are a revolution in medicine allowing the collection of such data in a continuous and organic way. However, it is still a challenge to make this information available to health care professionals to make decisions during clinical follow-up. OBJECTIVE: This study aims to build a digital solution that displays vital sign data from smartwatches, collected remotely, continuously, reliably, and from multiple users, with trigger warnings when abnormal results are identified. METHODS: This is a single-center prospective study following the guidelines "Evaluating digital health products" from the UK Health Security Agency. A digital platform with 3 different applications was created to capture and display data from the mobile phones of volunteers with smartwatches. We selected 80 volunteers who were followed for 24 weeks each, and the synchronization interval between the smartwatch and digital solution was recorded for each vital sign collected. RESULTS: In 14 weeks of project progress, we managed to recruit 80 volunteers, with 68 already registered in the digital solution. More than 2.8 million records have already been collected, without system downtime. Less than 5% of continuous heart rate measurements (bpm) were synchronized within 2 hours. However, approximately 70% were synchronized in less than 24 hours, and 90% were synchronized in less than 119 hours. CONCLUSIONS: The digital solution is working properly in its role of displaying data collected from smartwatches. Vital sign values are being monitored by the research team as part of the monitoring of volunteers. Although the digital solution proved unsuitable for monitoring urgent events, it is more than suitable for use in outpatient clinical use. This digital solution, which is based on cloud technology, can be applied in the future for telemonitoring in regions lacking health care professionals. Accuracy and reliability studies still need to be performed at the end of the 24-week follow-up.

Long-term functioning status of COVID-19 survivors: a prospective observational evaluation of a cohort of patients surviving hospitalisation.

OBJECTIVES: The study investigated the long-term functional status of hospitalised COVID-19 survivors to explore and document their functional situation. DESIGN: This prospective observational study assessed 801 COVID-19 survivors at 3-11 months after hospital discharge. It analyses participants' sociodemographic background, COVID-19 clinical manifestations, and clinical and functional evaluations. SETTING: Tertiary-level university hospital in São Paulo, Brazil. PARTICIPANTS: Study participants are COVID-19 survivors admitted to hospital care for at least 24 hours to treat acute SARS-CoV-2 infection. OUTCOME MEASURES: Epworth Sleepiness Scale, EuroQoL-5 Dimensions-5 Levels, Functional Assessment of Chronic Illness Therapy-Fatigue, Functional Independence Measure, Functional Oral Intake Scale, Handgrip Strength, Insomnia Severity Index, Medical Research Council (MRC) Dyspnea Scale, MRC sum score, Modified Borg Dyspnea Scale, pain Visual Analogue Scale, Post-COVID-19 Functional Status, Timed Up and Go, WHO Disability Assessment Schedule 2.0, 1-Minute Sit to Stand Test. RESULTS: Many participants required invasive mechanical ventilation (41.57%, 333 of 801). Mean age was 55.35±14.58 years. With a mean of 6.56 (SD: 1.58; 95% CI: 6.45 to 6.67) months after hospital discharge, 70.86% (567 of 800) reported limited daily activities, which were severe in 5.62% (45 of 800). They also reported pain and discomfort (64.50%, 516 of 800), breathlessness (64.66%, 514 of 795), and anxiety and depression (57.27%, 457 of 798). Daytime sleepiness and insomnia evaluations showed subthreshold results. Most (92.85%, 727 of 783) participants reported unrestricted oral intake. Data indicated no generalised fatigue (mean score: 39.18, SD: 9.77; 95% CI: 38.50 to 39.86). Assessments showed poor handgrip strength (52.20%, 379 of 726) and abnormal Timed Up and Go results (mean 13.07 s, SD: 6.49). The invasive mechanical ventilation group seemed to have a better handgrip strength however. We found no clear trends of change in their functional status during months passed since hospital discharge. CONCLUSIONS: Muscle weakness, pain, anxiety, depression, breathlessness, reduced mobility, insomnia and daytime sleepiness were the most prevalent long-term conditions identified among previously hospitalised COVID-19 survivors.
