RESUMEN
BACKGROUND: We developed a gap analysis that examines the role of brain-computer interfaces (BCI) in patients with disorders of consciousness (DoC), focusing on their assessment, establishment of communication, and engagement with their environment. METHODS: The Curing Coma Campaign convened a Coma Science work group that included 16 clinicians and neuroscientists with expertise in DoC. The work group met online biweekly and performed a gap analysis of the primary question. RESULTS: We outline a roadmap for assessing BCI readiness in patients with DoC and for advancing the use of BCI devices in patients with DoC. Additionally, we discuss preliminary studies that inform development of BCI solutions for communication and assessment of readiness for use of BCIs in DoC study participants. Special emphasis is placed on the challenges posed by the complex pathophysiologies caused by heterogeneous brain injuries and their impact on neuronal signaling. The differences between one-way and two-way communication are specifically considered. Possible implanted and noninvasive BCI solutions for acute and chronic DoC in adult and pediatric populations are also addressed. CONCLUSIONS: We identify clinical and technical gaps hindering the use of BCI in patients with DoC in each of these contexts and provide a roadmap for research aimed at improving communication for adults and children with DoC, spanning the clinical spectrum from intensive care unit to chronic care.
RESUMEN
Background: People with rare neurological diseases (RNDs) often experience symptoms related to movement disorders, requiring a multidisciplinary approach, including rehabilitation. Telemedicine applied to rehabilitation and symptom monitoring may be suitable to ensure treatment consistency and personalized intervention. The objective of this scoping review aimed to emphasize the potential role of telerehabilitation and teleassessment in managing movement disorders within RNDs. By providing a systematic overview of the available literature, we sought to highlight potential interventions, outcomes, and critical issues. Methods: A literature search was conducted on PubMed, Google Scholar, IEEE, and Scopus up to March 2024. Two inclusion criteria were followed: (1) papers focusing on telerehabilitation and teleassessment and (2) papers dealing with movement disorders in RNDs. Results: Eighteen papers fulfilled the inclusion criteria. The main interventions were home-based software and training programs, exergames, wearable sensors, smartphone applications, virtual reality and digital music players for telerehabilitation; wearable sensors, mobile applications, and patient home video for teleassessment. Key findings revealed positive outcomes in gait, balance, limb disability, and in remote monitoring. Limitations include small sample sizes, short intervention durations, and the lack of standardized protocols. Conclusion: This review highlighted the potential of telerehabilitation and teleassessment in addressing movement disorders within RNDs. Data indicate that these modalities may play a major role in supporting conventional programs. Addressing limitations through multicenter studies, longer-term follow-ups, and standardized protocols is essential. These measures are essential for improving remote rehabilitation and assessment, contributing to an improved quality of life for people with RNDs.
RESUMEN
BACKGROUND: Intensive Care Unit (ICU) survivors often experience several impairments in their physical, cognitive, and psychological health status, which are labeled as post-intensive care syndrome (PICS). The aim of this work is to develop a multidisciplinary and -professional guideline for the rehabilitative therapy of PICS. METHODS: A multidisciplinary/-professional task force of 15 healthcare professionals applied a structured, evidence-based approach to address 10 scientific questions. For each PICO-question (Population, Intervention, Comparison, and Outcome), best available evidence was identified. Recommendations were rated as "strong recommendation", "recommendation" or "therapy option", based on Grading of Recommendations, Assessment, Development and Evaluation principles. In addition, evidence gaps were identified. RESULTS: The evidence resulted in 12 recommendations, 4 therapy options, and one statement for the prevention or treatment of PICS. RECOMMENDATIONS: early mobilization, motor training, and nutrition/dysphagia management should be performed. Delirium prophylaxis focuses on behavioral interventions. ICU diaries can prevent/treat psychological health issues like anxiety and post-traumatic stress disorders. Early rehabilitation approaches as well as long-term access to specialized rehabilitation centers are recommended. Therapy options include additional physical rehabilitation interventions. Statement: A prerequisite for the treatment of PICS are the regular and repeated assessments of the physical, cognitive and psychological health in patients at risk for or having PICS. CONCLUSIONS: PICS is a variable and complex syndrome that requires an individual multidisciplinary, and multiprofessional approach. Rehabilitation of PICS should include an assessment and therapy of motor-, cognitive-, and psychological health impairments.

PURPOSE: ICU-acquired weakness, comprising Critical Illness Polyneuropathy (CIP) and Myopathy (CIM) is associated with immobilization and prolonged mechanical ventilation. This study aims to assess feasibility of early detection of CIP and CIM by peroneal nerve test (PENT) and sensory sural nerve action potential (SNAP) screening in patients with septic shock and invasively ventilated for more than 72 h. METHODS: We performed repetitive PENT screening from 72 h after intubation until detecting a pathological response. We tested SNAPs in pathological PENT to differentiate CIP from CIM. We performed muscle strength examination in awake patients and recorded time from intubation to first in-bed and out-of-bed mobilization. RESULTS: Eighteen patients were screened with PENT and 88.9% had abnormal responses. Mean time between intubation and first screening was 94.38 (± 22.41) hours. Seven patients (38.9%) had CIP, two (11.1%) had CIM, one (5.6%) had CIP and CIM, six (33.3%) had a pathological response on PENT associated with ICU-acquired weakness (but no SNAP could be performed to differentiate between CIP and CIM) and two patients had (11.1%) had no peripheral deficit. In patients where it could be performed, muscle strength testing concorded with electrophysiological findings. Twelve patients (66.7%) had out-of-bed mobilization 10.8 (± 7.4) days after admission. CONCLUSION: CIP and CIM are frequent in septic shock patients and can be detected before becoming symptomatic with simple bedside tools. Early detection of CIP and CIM opens new possibilities for their timely management through preventive measures such as passive and active mobilization.

Mechanical vibration of muscle tendons in specific frequencies - termed functional proprioceptive stimulation (FPS) - has the ability to induce the illusion of a movement which is congruent with a lengthening of the vibrated tendon and muscle. The majority of previous reports of the brain correlates of this illusion are based on functional neuroimaging. Contrary to the electroencephalogram (EEG) however, such technologies are not suitable for bedside or ambulant use. While a handful of studies have shown EEG changes during FPS, it remains underinvestigated whether these changes were due to the perceived illusion or the perceived vibration. Here, we aimed at disentangling the neural correlates of the illusory movement from those produced by the vibration sensation by comparing the neural responses to two vibration types, one that did and one that did not elicit an illusion. We recruited 40 naïve participants, 20 for the EEG experiment and 20 for a supporting behavioral study, who received functional tendon co-vibration on the biceps and triceps tendon at their left elbow, pseudo-randomly switching between the illusion and non-illusion trials. Time-frequency decomposition uncovered a strong and lasting event-related desynchronization (ERD) in the mu and beta band in both conditions, suggesting a strong somatosensory response to the vibration. Additionally, the analysis of the evoked potentials revealed a significant difference between the two experimental conditions from 310 to 990ms post stimulus onset. Training classifiers on the frequency-based and voltage-based correlates of illusion perception yielded above chance accuracies for 17 and 13 out of the 20 subjects respectively. Our findings show that FPS-induced illusions produce EEG correlates that are distinct from a vibration-based control and which can be classified reliably in a large number of participants. These results encourage pursuing EEG-based detection of kinesthetic illusions as a tool for clinical use, e.g., to uncover aspects of cognitive perception in unresponsive patients.

BACKGROUND AND PURPOSE: Early pharmacological support for post-stroke neurorehabilitation has seen an abundance of mixed results from clinical trials, leaving practitioners at a loss regarding the best options to improve patient outcomes. The objective of this evidence-based guideline is to support clinical decision-making of healthcare professionals involved in the recovery of stroke survivors. METHODS: This guideline was developed using the Grading of Recommendations, Assessment, Development and Evaluation (GRADE) framework. PubMed, Cochrane Library and Embase were searched (from database inception to June 2018, inclusive) to identify studies on pharmacological interventions for stroke rehabilitation initiated in the first 7 days (inclusive) after stroke, which were delivered together with neurorehabilitation. A sensitivity analysis was conducted on identified interventions to address results from breaking studies (from end of search to February 2020). RESULTS: Upon manually screening 17,969 unique database entries (of 57,001 original query results), interventions underwent meta-analysis. Cerebrolysin (30 ml/day, intravenous, minimum 10 days) and citalopram (20 mg/day, oral) are recommended for clinical use for early neurorehabilitation after acute ischaemic stroke. The remaining interventions identified by our systematic search are not recommended for clinical use: amphetamine (5, 10 mg/day, oral), citalopram (10 mg/day, oral), dextroamphetamine (10 mg/day, oral), Di-Huang-Yi-Zhi (2 × 18 g/day, oral), fluoxetine (20 mg/day, oral), lithium (2 × 300 mg/day, oral), MLC601(3 × 400 mg/day, oral), phosphodiesterase-5 inhibitor PF-03049423 (6 mg/day, oral). No recommendation 'for' or 'against' is provided for selegiline (5 mg/day, oral). Issues with safety and tolerability were identified for amphetamine, dextroamphetamine, fluoxetine and lithium. CONCLUSIONS: This guideline provides information for clinicians regarding existing pharmacological support in interventions for neurorecovery after acute ischaemic stroke. Updates to this material will potentially elucidate existing conundrums, improve current recommendations, and hopefully expand therapeutic options for stroke survivors.

The majority of patients with Coronavirus disease 2019 (COVID-19) present mild to moderate illness and recover without hospitalization. Nevertheless, 5 % of cases require hospitalization in the intensive care unit, with 15 % of them showing severe central and peripheral nervous system manifestations. These patients should be considered high risk patients and their management must include prevention of a potential accompanying cascade of negative factors. In order to optimize care, it is essential that signs of neurological damage are searched for as early as in intensive care so that appropriate neurorehabilitation can be started immediately and continued in a specific unit for patients with neurological sequelae at post-acute and outpatient phases.
La majorité des patients atteints par la maladie due au coronavirus 2019 (Covid-19) présente une évolution plutôt favorable. Cependant 5 % nécessitent une hospitalisation aux soins intensifs, dont 15 % présentent des atteintes sévères des systèmes nerveux central et périphérique. Ces patients doivent être considérés comme des personnes à haut risque de développer des séquelles graves et leur plan de traitement doit nécessairement impliquer la prévention d'une potentielle cascade de facteurs négatifs concomitants. Afin d'optimiser une telle prise en charge, il est primordial que les premiers signes d'atteintes neurologiques soient détectés dès les soins intensifs et qu'une neurorééducation puisse être débutée précocement et poursuivie dans une filière de patients neuro-lésés en phase postaiguë, puis en ambulatoire.

Disorders of consciousness (DOC) are a common consequence of severe brain injuries, and clinical evaluation is critical to provide a correct diagnosis and prognosis. The revised Motor Behavior Tool (MBT-r) is a clinical complementary tool aiming to identify subtle motor behaviors that might reflect residual cognition in DOC. In this prospective study including 30 DOC patients in the early stage after brain injury, we show that the revised MBT-r has an excellent inter-rater agreement and has the ability to identify a subgroup of patients, underestimated by the Coma Recovery Scale-Revised, showing residual cognition and a subsequent recovery of consciousness.

The International Association for the Study of Pain (IASP) proposed the current diagnostic description of complex regional pain syndrome (CRPS) for the distinct and complex chronic pain condition in 1994. Since this classification, studies on the syndrome have led to a better understanding of the underlying pathophysiological mechanisms, epidemiology and therapeutic approaches. F. Luthi of SUVA Care reviewed CRPS in detail in 2014 and 2019 issues of the Revue médicale suisse. The purpose of this article is to provide an update of results on the neural mechanisms involved in this syndrome and how this helps management of CRPS, in particular bringing awareness to physicians of all specialties of the first symptoms with practical advice for investigations and treatment.
Le syndrome douloureux régional complexe (SDRC) a été défini en 1994 par l'International Association for the Study of Pain (IASP). Depuis cette définition, les études concernant ce syndrome ont permis une meilleure compréhension quant aux mécanismes physiopathologiques sous-jacents, à l'épidémiologie et aux approches thérapeutiques. Le SDRC a déjà été bien décrit dans deux numéros de la Revue médicale suisse de 2014 et 2019 par F. Luthi de la Clinique romande de réadaptation (SUVACare). Le but de cet article est de rapporter les connaissances récentes sur les mécanismes neuronaux impliqués dans ce syndrome et impactant la prise en charge. Nous souhaitons sensibiliser les médecins de toutes spécialités à la reconnaissance des premiers symptômes et diffuser des conseils pratiques quant aux investigations et aux traitements.

Spasticity is a common sign of central nervous system lesions and its management is difficult because it is usually associated with other symptoms of upper motoneuron syndrome (paresis, spastic dystonia, contractures, ). We propose an interprofessional evaluation, which demonstrates that a standardized evaluation, a common approach and a gait analysis improve the therapeutic decision.
La spasticité est très fréquente après une lésion du système nerveux central, et sa prise en charge demeure difficile, car elle se combine avec d'autres symptômes caractéristiques du syndrome du motoneurone supérieur (parésie, dystonie spastique, contractures ). Afin de faciliter le choix thérapeutique, nous présentons le modèle d'une évaluation interprofessionnelle, qui démontre qu'une évaluation standardisée, une approche commune et une analyse de la marche permettent une meilleure prise en charge thérapeutique.

One part of the population of neurolesioned patients is the transition of young patients with neurodisabilities to adult life. To guarantee favourable social and professional reinsertion is a major challenge, requiring inter-professional care. For this reason, in 2006 the CHUV, Lausanne created a transition-consultation framework with neuro-paediatricians and adult neurologists specialised in neuro-rehabilitation linked to a Swiss pilot social and professional reinsertion project collaborating with the invalidity insurance. As a model of the follow up of neurolesioned patients, this article reports the results of the reinsertion project that aims to bring awareness to the general practitioner of an inter-disciplinary care method adaptable to individuals. The holistic service saves time and improves the rate of successful reinsertion of young adults into social and professional life.
Les jeunes en transition de l'enfance à l'âge adulte présentant une maladie neurodéveloppementale sont une population spécialement vulnérable. Le suivi de leurs problèmes de santé et leur insertion socioprofessionnelle représentent un véritable défi. Au CHUV, à Lausanne, une consultation de transition entre les neurorééducateurs pédiatriques et adultes a été créée en 2006 ainsi qu'un projet pilote suisse de réinsertion socioprofessionnelle en collaboration avec l'Office de l'assurance invalidité pour le canton de Vaud. Le résultat de ce projet pilote, qui peut être utilisé comme modèle pour tous les patients neurolésés, est rapporté ici avec comme objectif d'informer le médecin traitant et de lui permettre d'utiliser les outils de cette prestation holistique afin d'optimiser la durée et la qualité de la réinsertion.

New studies confirm the possibility of late thrombolysis. Meta-analyses have confirmed that CGRP inhibitors are efficacious for migraines. Cladribine is a new oral treatment for relapsing-remitting multiple sclerosis. Limbic-predominant age-related TDP-43 encephalopathy (LATE) is a new clinical entity accounting for cognitive decline in old patients. The timing of levodopa introduction has no effect on the long-term course of idiopathic Parkinson's disease. Hypophosphatemia helps distinguish between seizures and syncopes in the emergency department. A second course of intravenous immunoglobulins provides no benefit for severe Guillain Barre syndrome. Outdoor therapy improves clinical scales in patients with disorder of consciousness. Ultrasound guided lumbar puncture improves the yield of the procedure.
De nouvelles études confirment la possibilité de thrombolyse tardive. Les méta-analyses confirment l'effet bénéfique des inhibiteurs du CGRP (calcitonin gene-related peptide) pour la migraine. La cladribine est un nouveau traitement oral pour la sclérose en plaque de type poussée-rémission. L'encéphalopathie à TDP-43 à prédominance limbique est une nouvelle entité en lien avec des troubles cognitifs de la personne âgée. Le délai d'introduction de la lévodopa n'a pas d'influence sur l'évolution à long terme de la maladie de Parkinson. L'hypophosphatémie aide à différencier les crises d'épilepsie des syncopes. Une deuxième cure d'immunoglobulines n'apporte pas de bénéfice dans le traitement du syndrome de Guillain-Barré. Les patients avec troubles de l'état de conscience bénéficient des thérapies à l'air libre. L'ultrason améliore le rendement de la ponction lombaire.

BACKGROUND: In stroke patients, early complications such as swallowing disorders (SD) and bronchopneumonia (BP) are frequent and may worsen outcome. The aim of this study was to evaluate the prevalence of SD in acute ischemic stroke (AIS) and the risk of BP, as well as to identify factors associated with these conditions. METHODS: We retrospectively studied all AISs over a 12-month period in a single-center registry. We determined the frequency of SD in the first 7 days and of BP over the entire hospital stay. Associations of SD and BP with patient characteristics, stroke features, dental status, and presence of a feeding tube were analyzed in multivariate analyses. RESULTS: In the 340 consecutive patients, the overall frequency of SD and BP was 23.8% and 11.5%, respectively. The multivariate analyses showed significant associations of SD with NIHSS scores >4, involvement of the medulla oblongata and wearing a dental prosthesis (area under the receiver-operator curve (AUC) of 76%). BP was significantly associated with NIHSS scores >4, male sex, bilateral cerebral lesions, the presence of SD, and the use of an enteral feeding tube (AUC 84%). In unadjusted analysis, unfavorable 12-month outcome and mortality were increased in the presence of SD. CONCLUSION: In AIS, SD and BP are associated with stroke severity and localization and wearing a dental prosthesis increases the risk of SD. Given that patients with SD have an increased risk of poor outcome and mortality, high-risk patients warrant early interventions, including more randomized trials.

New treatment modalities in oncology, radiation oncology and surgery have led to a significant improvement in life expectancy for cancer patients. Some will however develop severe neurologic deficits that will impact their quality of life. To limit this impact, it is essential to offer optimal neurorehabilitation. In this context, a pilot project of early and intensive neurorehabilitation for brain tumor patients has been set up. A collaboration between the teams of neurooncology, acute neurorehabilitation and neurosurgery from the CHUV and the Clinique La Lignière allows an intensive and direct neurorehabilitation following neurosurgery. This neuroreeducation has allowed 75% of the patients included in this program to return home.

PURPOSE OF REVIEW: The purpose of this review is to provide an update on the latest challenges addressed by neurorehabilitation initiated very early after the brain damage, such as dealing with disorders of consciousness in terms of diagnosis, prognosis and rehabilitative treatment, or determining best timing for first rehabilitative intervention, best therapeutic approaches and best modalities. RECENT FINDINGS: Early management of patients with severe brain damage requires a multidisciplinary rehabilitative approach that encompasses clinical skills in various fields, standard therapies, and assistive technologies.Despite a high rate of misdiagnosis and poor outcome prediction in disorders of consciousness, the observation of subtle motor signs may be a promising way to reach accurate diagnosis and better outcome prediction. Neurosensory stimulation remains the current treatment to promote emergence from disorders of consciousness.Early timing of neurological rehabilitation is definitively efficient, but a safety period should be respected. Some standard therapies and assistive technologies have demonstrated explicit evidence in neurological recovery and high treatment dose is needed to emphasize the therapeutic effect, but several controversies persist in treatment evidence. SUMMARY: Current advancements have provided growing evidence for early neurorehabilitation, which should be definitively applied, but further studies are explicitly needed to diminish persistent controversies in the field.

STUDY DESIGN: Clinical measurement. PURPOSE: The test-retest reliability of maximal grip strength measurements (MGSM) is examined in subjects for 12 weeks post-stroke together with maximal grip strength recovery and the maximal-grip and upper-extremity strength measurements' relationship with capacity and performance test scores. METHODS: A Jamar dynamometer and the Motricity Index (MI) were used for strength measurements. The Chedoke Arm and Hand Activity Inventory and ABILHAND questionnaire for evaluating capacities and performances. RESULTS: MGSM were reliable (Intraclass Correlation Coefficients = 0.97-0.99, Minimal Detectable Differences = 2.73-4.68 kg). Among the 34 participants, 47% did not have a measurable grip strength one week post-stroke but 50% of these recovered some strength within the first eight weeks. The MGSM and MI scores were correlated with scores of tests of capacity and performance (Spearman's Rank Correlation Coefficients = 0.69-0.94). CONCLUSIONS: MGSM are reliable in the first weeks after a stroke. LEVEL OF EVIDENCE: N/A.

The aim of this prospective, observational cohort study was to investigate and assess diverse neuroimaging biomarkers to predict patients' neurological recovery after coma. 32 patients (18-76 years, M = 44.8, SD = 17.7) with disorders of consciousness participated in the study. Multimodal neuroimaging data acquired during the patient's hospitalization were used to derive cortical glucose metabolism (18F-fluorodeoxyglucose positron emission tomography/computed tomography), and structural (diffusion-weighted imaging) and functional connectivity (resting-state functional MRI) indices. The recovery outcome was defined as a continuous composite score constructed from a multivariate neurobehavioral recovery assessment administered upon the discharge from the hospital. Fractional anisotropy-based white matter integrity in the anterior forebrain mesocircuit (r = 0.72, p < .001, 95% CI: 0.87, 0.45), and the functional connectivity between the antagonistic default mode and dorsal attention resting-state networks (r = - 0.74, p < 0.001, 95% CI: - 0.46, - 0.88) strongly correlated with the recovery outcome. The association between the posterior glucose metabolism and the recovery outcome was moderate (r = 0.38, p = 0.040, 95% CI: 0.66, 0.02). Structural (adjusted R2 = 0.84, p = 0.003) or functional connectivity biomarker (adjusted R2 = 0.85, p = 0.001), but not their combination, significantly improved the model fit to predict the recovery compared solely to bedside neurobehavioral evaluation (adjusted R2 = 0.75). The present study elucidates an important role of specific MRI-derived structural and functional connectivity biomarkers in diagnosis and prognosis of recovery after coma and has implications for clinical care of patients with severe brain injury.
RESUMEN
Currently, very little is known about the holistic outcome of patients recovering from coma. The aim of this retrospective exploratory study was to evaluate the outcomes of patients recovering from coma after care in an acute neurorehabilitation unit with particular focus on their biopsychosocial and spiritual needs in the post-acute phase of recovery. We included 12 patients and evaluated clinical outcome evolution by comparing standard neurobehavioral scores from patient files measured in the acute and post-acute phases. We assessed patient needs using the Quality of Life after Brain Injury scale (QOLIBRI) and classified self-reported complaints mentioned in patient files according to the International Classification of Functioning, Disability and Health framework (ICF). Mean patient evolution was a Level of Cognitive Functioning Scale (LCF)-r increase of 3.33 levels (range = 2); a Disability Rating Scale score (DRS) of -3.27 points (SD = 3.78); a Functional Ambulation Classification (FAC) scale score of 1.83 (range = 5); and a Glasgow Outcome Scale (GOS) median = 0 (Interquartile range = 1). Main patient complaints concerned mental functioning (n = 7), sensory functioning and pain (n = 6), neuromusculoskeletal and movement problems (n = 5), and major life areas (n = 5). To conclude, a significant handicap that affects their daily life was present in the post-acute phase in most patients. Complaints involved biopsychosocial and spiritual elements. The neurobehavioral scale results do not necessarily correlate with the subjective representations patients had of their condition.
