[Certification by the German Society for Neurorehabiliation, DGNR : Performance and quality of the "Centers for weaning from a ventilator in early neurological and neurosurgical rehabilitation"]. / Zertifizierung der Deutschen Gesellschaft für Neurorehabilitation e. V., DGNR : Leistung und Qualität der "Zentren für Beatmungsentwöhnung in der neurologisch-neurochirurgischen Frührehabilitation".

BACKGROUND: Certification of centers for weaning from a ventilator in neurological neurosurgical early rehabilitation (NNER) by the German Society for Neurorehabilitation (DGNR) is possible since 1 October 2021. OBJECTIVE: The results of certification of facilities in the first year after starting the procedure are presented. MATERIAL AND METHODS: As part of the certification process 28 criteria are assessed including a set of mandatory characteristics of the facility. The criteria are divided into structural criteria (i = 7), diagnostic criteria (i = 6), personnel criteria (i = 3), internal organization criteria (i = 7), and quality management criteria (i = 5). RESULTS: A total of 13 centers were certified in the first year, with a combined total of 283 beds for weaning from a ventilator in the NNER and served 2278 persons to be weaned from a ventilator in the year before certification, with a median of 134 per facility (range 44-414). Only rarely was weaning unsuccessful, requiring conversion to home mechanical ventilation before discharge (invasive home mechanical ventilation median per facility 10 persons, range 2-25; non-invasive home mechanical ventilation median 0 persons, range 0-57). A high level of process and structural quality was documented for the certified centers: across all areas of assessment, the individual certification criteria were met in the vast majority of cases (median degree of complete fulfilment 86%) or met with improvement potentials documented by the auditors (median 11%). CONCLUSION: Successful weaning in NNER and a high level of process and structural quality can be demonstrated by the certification results of centers that follow this integrative approach to weaning from a ventilator in a NNER setting.

S2k-Leitlinie SARS-CoV-2, COVID-19 und (Früh-) Rehabilitation ­ eine Kurzfassung mit allen Empfehlungen im Überblick.

The consensus-based SARS-CoV-2, COVID-19, and Rehabilitation Practice Guideline provides recommendations that take both infection prevention and the pursuit of therapeutic goals in rehabilitation settings during the coronavirus pandemic into account. The Practice Guideline provides guidance how to prevent SARS-CoV-2 infections in rehabilitation settings in a first part. The guideline's second part addresses rehabilitation for patients affected by COVID-19 starting with interventions on intensive care units, during early rehabilitation, post-acute rehabilitation, in outpatient and community rehabilitation settings, as well as long-term care, e. g. for COVID-19 survivors with Long- or Post-COVID.The updated second version of the Practice Guideline (dating from 01.11.2021) is a consensus-based guideline developed by a representative panel of healthcare professionals from 15 medical societies covering various rehabilitation disciplines, infectious diseases, hospital hygiene, and epidemiology. The abbreviated version provides an overview of all recommendations given.

[Slow demographic change and neurological rehabilitation-Part 2: what we can do]. / Schleichender demografischer Wandel und neurologische Rehabilitation ­ Teil 2: Handlungsmöglichkeiten.

In its current state the German healthcare system will not be able to adequately care for a growing proportion of older patients with a decreasing healthcare work force. This is particularly so in the postacute care of severely ill patients. In a second of two parts we discuss the perspectives and options at hand. A major conclusion is that substantial gains could be obtained by regulatory adjustments that better align acute care and rehabilitative measures.

[Slow demographic change and neurological rehabilitation-Part 1: state of affairs]. / Schleichender demografischer Wandel und neurologische Rehabilitation ­ Teil 1: Situationsbeschreibung.

In the next two decades the aging baby boomers in Germany will gradually be leaving the work force. They are being followed by the much less numerous, "baby bust" generation who now need to finance and staff healthcare for the growing number of old people in society. In order to care for more needy persons with a smaller working population, the healthcare system must be restructured; however, despite these worrisome prospects, the awareness of the problem is still low in many areas. Here we focus on the area in the healthcare system that is growing particularly rapidly and additionally has the greatest need of personnel per patient: the care of the critically ill and functionally impaired patients. The lack of coordination of hospitals, rehabilitation centers and nursing institution is historical in origin. It promotes the tendency to discharge functionally impaired patients to nursing facilities without giving them a chance for recovery of functional autonomy. As the demographic change progresses, this tendency threatens to increase. In a first of two parts, we attempt to describe the present situation.

Optimizing home-based long-term intensive care for neurological patients with neurorehabilitation outreach teams - protocol of a multicenter, parallel-group randomized controlled trial (OptiNIV-Study).

BACKGROUND: Even with high standards of acute care and neurological early rehabilitation (NER) a substantial number of patients with neurological conditions still need mechanical ventilation and/or airway protection by tracheal cannulas when discharged and hence home-based specialised intensive care nursing (HSICN). It may be possible to improve the home care situation with structured specialized long-term neurorehabilitation support and following up patients with neurorehabilitation teams. Consequently, more people might recover over an extended period to a degree that they were no longer dependent on HSICN. METHODS: This healthcare project and clinical trial implements a new specialised neurorehabilitation outreach service for people being discharged from NER with the need for HSICN. The multicentre, open, parallel-group RCT compares the effects of one year post-discharge specialized outpatient follow-up to usual care in people receiving HSICN. Participants will randomly be assigned to receive the new form of healthcare (intervention) or the standard healthcare (control) on a 2:1 basis. Primary outcome is the rate of weaning from mechanical ventilation and/or decannulation (primary outcome) after one year, secondary outcomes include both clinical and economic measures. 173 participants are required to corroborate a difference of 30 vs. 10% weaning success rate statistically with 80% power at a 5% significance level allowing for 15% attrition. DISCUSSION: The OptiNIV-Study will implement a new specialised neurorehabilitation outreach service and will determine its weaning success rates, other clinical outcomes, and cost-effectiveness compared to usual care for people in need for mechanical ventilation and/or tracheal cannula and hence HSICN after discharge from NER. TRIAL REGISTRATION: The trial OptiNIV has been registered in the German Clinical Trials Register (DRKS) since 18.01.2022 with the ID DRKS00027326 .

[Rehabilitation with coronavirus disease with SARS-CoV-2 (COVID-19)]. / Rehabilitation bei Coronavirus-Erkrankung mit SARS-CoV-2 (COVID-19).

The Coronavirus disease with SARS-CoV-2 viral infection (COVID-19) and its diverse courses of disease from mild to critical illness frequently is not only an acute disease, but will - in a proportion of those affected - lead to organ structure and body function deficits that still exist or become apparent after the acute stage of disease. When clinically relevant symptoms or functional deficits (impairments) are documented more than four weeks after COVID-19 onset, the syndrome is called "Long-COVID", from 12 weeks after onset onwards "Post-COVID".In such cases and when everyday life functioning and return to work are affected by persisting deficits specialized rehabilitation treatment is indicated. An individual medical, frequently multi-professional diagnostic evaluation is mandatory in that situation: For adequate treatment, it is important to identify and objectify the individually underlying health conditions based on knowledge about the diverse potential consequences of COVID-19, to assess type and severity of functional consequences (impairments, activity limitations, and restrictions of participation) of Long-/Post-COVID individually, and then to decide on the treatment necessities and plans. With regard to rehabilitation, need and decision for either pulmonary, neurological, cardiac, or psychosomatic rehabilitation depends on the individual medical presentation.

[The certification of centers for weaning from mechanical ventilation in neurological and neurosurgical early rehabilitation by the German Society for Neurorehabilitation]. / Die Zertifizierung von Zentren für Beatmungsentwöhnung in der neurologisch-neurochirurgischen Frührehabilitation durch die Deutsche Gesellschaft für Neurorehabilitation.

Specialized centers for weaning in neurological and neurosurgical early rehabilitation can be certified by the German Society for Neurorehabilitation (DGNR) since 1 October 2021. The certification criteria are indicators for structure and process quality and for treatment results for weaning of neurological patients from mechanical ventilation. In Germany these patients are treated in departments for neurological and neurosurgical early rehabilitation in acute care hospitals as well as in specialized rehabilitation hospitals. Acknowledging this diversity of care, certification is possible for both kinds of institutions. Certification is granted by the DGNR in cooperation with TÜV Rheinland as the certification authority, analogous to the certification of stroke units. Institutions apply for certification by sending all necessary documents to the TÜV Rheinland. Afterwards auditors of the TÜV Rheinland (lead auditor) and the DGNR (medical speciality auditor) visit the institution on site. The results of this visit are reported to the certification committee of the DGNR, which in turn recommends or declines certification. The certification of centers for weaning in neurological and neurosurgical early rehabilitation is an important step towards defining neurorespiratory care and the role of the neurologist for intensive care and weaning in Germany. Thereby, the interdisciplinary dialogue between pneumologists, anesthesiologists, and neurologists is fostered. Also, the dialogue on treatment capacities and strategies with healthcare politicians, health insurances, and patient associations is facilitated.

[Evidence-based Practice Guidelines for the German Society for Neurology (DGN) and the German Society for Neurorehabilitation (DGNR): Methods for systematic evidence-to-decision process]. / Evidenzbasierte Leitlinienentwicklung der Deutschen Gesellschaft für Neurologie (DGN) und der Deutschen Gesellschaft für Neurorehabilitation (DGNR) - Methodik für die systematische Evidenzbasierung.

Evidence-based guidelines of high quality, which are prepared either by a scientific medical association (S2e guidelines) or by an interdisciplinary group of different medical associations (S3 guidelines), represent a combination of the best available external evidence (from clinical trials) and the recommendations derived from it for clinical practice. In the case of an interdisciplinary development, the recommendations are also formally agreed upon in a structured consensus process. They thus generate a high degree of certainty for clinicians that the state of the art is adequately taken into account in their decisions. Based on the guideline development methodology of the Association of Scientific Medical Societies (AWMF), the DGN and DGNR have agreed on standards for the implementation of the guideline development methodology for the evidence-based development of their guidelines, which are documented here. They make it clear to readers and users of evidence-based guidelines which content-related and methodological aspects have to be taken into account if practice recommendations are to be derived from and based on data available from clinical studies.

[S1 Guideline Post-COVID/Long-COVID]. / S1-Leitlinie Post-COVID/Long-COVID.

The German Society of Pneumology initiated the AWMFS1 guideline Post-COVID/Long-COVID. In a broad interdisciplinary approach, this S1 guideline was designed based on the current state of knowledge.The clinical recommendation describes current post-COVID/long-COVID symptoms, diagnostic approaches, and therapies.In addition to the general and consensus introduction, a subject-specific approach was taken to summarize the current state of knowledge.The guideline has an expilcit practical claim and will be continuously developed and adapted by the author team based on the current increase in knowledge.

[Weaning in neurological and neurosurgical early rehabilitation-Results from the "WennFrüh" study of the German Society for Neurorehabilitation]. / Weaning in der neurologisch-neurochirurgischen Frührehabilitation ­ Ergebnisse der "WennFrüh"-Studie der Deutschen Gesellschaft für Neurorehabilitation.

Neurological and neurosurgical early rehabilitation patients are often so critically ill that they must be weaned from mechanical ventilation in addition to early rehabilitative treatment. The German Society for Neurorehabilitation (DGNR) carried out a survey and asked neurological weaning units to provide information on structural characteristics of the facility, including personnel and technical resources and the number of cases and outcome based on anonymous data. In total 36 weaning units from 11 federal states with a total of 496 beds participated in the survey. From 2516 weaning cases documented in 2019, 2097 (83.3%) could primarily be successfully weaned from mechanical ventilation and only 120 (4.8%) had to be discharged with home ventilation. The mortality in this sample was 11.0% (n = 276). The results of the survey demonstrate that prolonged weaning during early neurological and neurosurgical rehabilitation is an important and effective component of healthcare provision for critically ill patients in Germany.

Electromechanical and robot-assisted arm training for improving activities of daily living, arm function, and arm muscle strength after stroke.

BACKGROUND: Electromechanical and robot-assisted arm training devices are used in rehabilitation, and may help to improve arm function after stroke. OBJECTIVES: To assess the effectiveness of electromechanical and robot-assisted arm training for improving activities of daily living, arm function, and arm muscle strength in people after stroke. We also assessed the acceptability and safety of the therapy. SEARCH METHODS: We searched the Cochrane Stroke Group's Trials Register (last searched January 2018), the Cochrane Central Register of Controlled Trials (CENTRAL) (the Cochrane Library 2018, Issue 1), MEDLINE (1950 to January 2018), Embase (1980 to January 2018), CINAHL (1982 to January 2018), AMED (1985 to January 2018), SPORTDiscus (1949 to January 2018), PEDro (searched February 2018), Compendex (1972 to January 2018), and Inspec (1969 to January 2018). We also handsearched relevant conference proceedings, searched trials and research registers, checked reference lists, and contacted trialists, experts, and researchers in our field, as well as manufacturers of commercial devices. SELECTION CRITERIA: Randomised controlled trials comparing electromechanical and robot-assisted arm training for recovery of arm function with other rehabilitation or placebo interventions, or no treatment, for people after stroke. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, assessed trial quality and risk of bias, used the GRADE approach to assess the quality of the body of evidence, and extracted data. We contacted trialists for additional information. We analysed the results as standardised mean differences (SMDs) for continuous variables and risk differences (RDs) for dichotomous variables. MAIN RESULTS: We included 45 trials (involving 1619 participants) in this update of our review. Electromechanical and robot-assisted arm training improved activities of daily living scores (SMD 0.31, 95% confidence interval (CI) 0.09 to 0.52, P = 0.0005; I² = 59%; 24 studies, 957 participants, high-quality evidence), arm function (SMD 0.32, 95% CI 0.18 to 0.46, P < 0.0001, I² = 36%, 41 studies, 1452 participants, high-quality evidence), and arm muscle strength (SMD 0.46, 95% CI 0.16 to 0.77, P = 0.003, I² = 76%, 23 studies, 826 participants, high-quality evidence). Electromechanical and robot-assisted arm training did not increase the risk of participant dropout (RD 0.00, 95% CI -0.02 to 0.02, P = 0.93, I² = 0%, 45 studies, 1619 participants, high-quality evidence), and adverse events were rare. AUTHORS' CONCLUSIONS: People who receive electromechanical and robot-assisted arm training after stroke might improve their activities of daily living, arm function, and arm muscle strength. However, the results must be interpreted with caution although the quality of the evidence was high, because there were variations between the trials in: the intensity, duration, and amount of training; type of treatment; participant characteristics; and measurements used.

We contacted trialists for additional information. We analysed the results as standardised mean differences (SMDs) for continuous variables and risk differences (RDs) for dichotomous variables. MAIN RESULTS: We included 34 trials (involving 1160 participants) in this update of our review. Electromechanical and robot-assisted arm training improved activities of daily living scores (SMD 0.37, 95% confidence interval (CI) 0.11 to 0.64, P = 0.005, I² = 62%), arm function (SMD 0.35, 95% CI 0.18 to 0.51, P < 0.0001, I² = 36%), and arm muscle strength (SMD 0.36, 95% CI 0.01 to 0.70, P = 0.04, I² = 72%), but the quality of the evidence was low to very low. Electromechanical and robot-assisted arm training did not increase the risk of participant drop-out (RD 0.00, 95% CI -0.02 to 0.03, P = 0.84, I² = 0%) with moderate-quality evidence, and adverse events were rare. AUTHORS' CONCLUSIONS: People who receive electromechanical and robot-assisted arm and hand training after stroke might improve their activities of daily living, arm and hand function, and arm and hand muscle strength. However, the results must be interpreted with caution because the quality of the evidence was low to very low, and there were variations between the trials in the intensity, duration, and amount of training; type of treatment; and participant characteristics.

Sequential evolution of cortical activity and effective connectivity of swallowing using fMRI.

Swallowing consists of a hierarchical sequence of primary motor and somatosensory processes. The temporal interplay of different phases is complex and clinical disturbances frequent. Of interest was the temporal interaction of the swallowing network. Time resolution optimized functional magnetic resonance imaging was used to describe the temporal sequence of representation sites of swallowing and their functional connectivity. Sixteen young healthy volunteers were investigated who swallowed 2 ml of water 20 times per run with a repetition time for functional imaging of 514 ms. After applying the general linear model approach to identify activation magnitude in preselected regions of interest repeated measures analysis of variance (rmANOVA) was used to detect relevant effects on lateralization, time, and onset. Furthermore, dynamic causal modeling (DCM) was applied to uncover where the input enters the model and the way in which the cortical regions are connected. The temporal analysis revealed a successive activation starting at the premotor cortex, supplementary motor area (SMA), and bilateral thalamus, followed by the primary sensorimotor cortex, the posterior insula, and cerebellum and culminating with activation in the pons shortly before subsiding. The rmANOVA revealed that activation was lateralized initially to the left hemisphere and gradually moved to the right hemisphere over time. The group random effects DCM analysis resulted in a most likely model that consisted of inputs to SMA and M1S1, bidirectionally connected, and a one-way connection from M1S1 to the posterior insula.

Feasibility, coverage, and inter-rater reliability of the assessment of therapeutic interaction by a humanoid robot providing arm rehabilitation to stroke survivors using the instrument THER-I-ACT.

Objective: The instrument THERapy-related InterACTion (THER-I-ACT) was developed to document therapeutic interactions comprehensively in the human therapist-patient setting. Here, we investigate whether the instrument can also reliably be used to characterise therapeutic interactions when a digital system with a humanoid robot as a therapeutic assistant is used. Methods: Participants and therapy: Seventeen stroke survivors receiving arm rehabilitation (i.e., arm basis training (ABT) for moderate-to-severe arm paresis [n = 9] or arm ability training (AAT) for mild arm paresis [n = 8]) using the digital therapy system E-BRAiN over a course of nine sessions. Analysis of the therapeutic interaction: A total of 34 therapy sessions were videotaped. All therapeutic interactions provided by the humanoid robot during the first and the last (9th) session of daily training were documented both in terms of their frequency and time used for that type of interaction using THER-I-ACT. Any additional therapeutic interaction spontaneously given by the supervising staff or a human helper providing physical assistance (ABT only) was also documented. All ratings were performed by two trained independent raters. Statistical analyses: Intraclass correlation coefficients (ICCs) were calculated for the frequency of occurrence and time used for each category of interaction observed. Results: Therapeutic interactions could comprehensively be documented and were observed across the dimensions provision of information, feedback, and bond-related interactions. ICCs for therapeutic interaction category assessments from 34 therapy sessions by two independent raters were high (ICC ≥0.90) for almost all categories of the therapeutic interaction observed, both for the occurrence frequency and time used for categories of therapeutic interactions, and both for the therapeutic interaction performed by the robot and, even though much less frequently observed, additional spontaneous therapeutic interactions by the supervisory staff and a helper being present. The ICC was similarly high for an overall subjective rating of the concentration and engagement of patients (0.87). Conclusion: Therapeutic interactions can comprehensively and reliably be documented by trained raters using the instrument THER-I-ACT not only in the traditional patient-therapist setting, as previously shown, but also in a digital therapy setting with a humanoid robot as the therapeutic agent and for more complex therapeutic settings with more than one therapeutic agent being present.

Analysis of the therapeutic interaction provided by a humanoid robot serving stroke survivors as a therapeutic assistant for arm rehabilitation.

Objective: To characterize a socially active humanoid robot's therapeutic interaction as a therapeutic assistant when providing arm rehabilitation (i.e., arm basis training (ABT) for moderate-to-severe arm paresis or arm ability training (AAT) for mild arm paresis) to stroke survivors when using the digital therapeutic system Evidence-Based Robot-Assistant in Neurorehabilitation (E-BRAiN) and to compare it to human therapists' interaction. Methods: Participants and therapy: Seventeen stroke survivors receiving arm rehabilitation (i.e., ABT [n = 9] or AAT [n = 8]) using E-BRAiN over a course of nine sessions and twenty-one other stroke survivors receiving arm rehabilitation sessions (i.e., ABT [n = 6] or AAT [n = 15]) in a conventional 1:1 therapist-patient setting. Analysis of therapeutic interaction: Therapy sessions were videotaped, and all therapeutic interactions (information provision, feedback, and bond-related interaction) were documented offline both in terms of their frequency of occurrence and time used for the respective type of interaction using the instrument THER-I-ACT. Statistical analyses: The therapeutic interaction of the humanoid robot, supervising staff/therapists, and helpers on day 1 is reported as mean across subjects for each type of therapy (i.e., ABT and AAT) as descriptive statistics. Effects of time (day 1 vs. day 9) on the humanoid robot interaction were analyzed by repeated-measures analysis of variance (rmANOVA) together with the between-subject factor type of therapy (ABT vs. AAT). The between-subject effect of the agent (humanoid robot vs. human therapist; day 1) was analyzed together with the factor therapy (ABT vs. AAT) by ANOVA. Main results and interpretation: The overall pattern of the therapeutic interaction by the humanoid robot was comprehensive and varied considerably with the type of therapy (as clinically indicated and intended), largely comparable to human therapists' interaction, and adapted according to needs for interaction over time. Even substantially long robot-assisted therapy sessions seemed acceptable to stroke survivors and promoted engaged patients' training behavior. Conclusion: Humanoid robot interaction as implemented in the digital system E-BRAiN matches the human therapeutic interaction and its modification across therapies well and promotes engaged training behavior by patients. These characteristics support its clinical use as a therapeutic assistant and, hence, its application to support specific and intensive restorative training for stroke survivors.

S2k-Guideline SARS-CoV-2, COVID-19 and (early) rehabilitation - a consensus-based guideline for Germany.

The consensus-based guideline "SARS-CoV-2, COVID-19 and (early) rehabilitation" for Germany has two sections: In the first part, the guideline addresses infection protection-related procedures during the COVID-19 pandemic. In the second part, it provides practice recommendations for rehabilitation after COVID-19. The specific recommendations for rehabilitation after COVID-19 as issued by 13 German medical societies and two patient-representative organizations are presented together with general background information for their development.

Electromechanical and robot-assisted arm training for improving generic activities of daily living, arm function, and arm muscle strength after stroke.

BACKGROUND: Electromechanical and robot-assisted arm training devices are used in rehabilitation, and might help to improve arm function after stroke. OBJECTIVES: To assess the effectiveness of electromechanical and robot-assisted arm training for improving generic activities of daily living, arm function, and arm muscle strength in patients after stroke. We will also assess the acceptability and safety of the therapy. SEARCH METHODS: We searched the Cochrane Stroke Group's Trials Register (last searched July 2011), the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2011, Issue 7), MEDLINE (1950 to July 2011), EMBASE (1980 to July 2011), CINAHL (1982 to July 2011), AMED (1985 to July 2011), SPORTDiscus (1949 to July 2011), PEDro (searched August 2011), COMPENDEX (1972 to July 2011), and INSPEC (1969 to July 2011). We also handsearched relevant conference proceedings, searched trials and research registers, checked reference lists, and contacted trialists, experts and researchers in our field, as well as manufacturers of commercial devices. SELECTION CRITERIA: Randomised controlled trials (RCTs) comparing electromechanical and robot-assisted arm training for recovery of arm function with other rehabilitation or placebo interventions, or no treatment, for patients after stroke. DATA COLLECTION AND ANALYSIS: Two review authors independently selected trials for inclusion, assessed trial quality, and extracted data. We contacted trialists for additional information. We analysed the results as standardised mean differences (SMDs) for continuous variables and risk differences (RDs) for dichotomous variables. MAIN RESULTS: We included 19 trials (involving 666 participants) in this update of our review. Electromechanical and robot-assisted arm training did improve activities of daily living (SMD 0.43, 95% confidence interval (CI) 0.11 to 0.75, P = 0.009, I(2) = 67%) as well as arm function (SMD 0.45, 95% CI 0.20 to 0.69, P = 0.0004, I(2) = 45%), but arm muscle strength did not improve (SMD 0.48, 95% CI -0.06 to 1.03, P = 0.08, I(2) = 79%). Electromechanical and robot-assisted arm training did not increase the risk of patients to drop out (RD 0.00, 95% CI -0.04 to 0.04, P = 0.82, I(2) = 0.0%), and adverse events were rare. AUTHORS' CONCLUSIONS: Patients who receive electromechanical and robot-assisted arm training after stroke are more likely to improve their generic activities of daily living. Paretic arm function may also improve, but not arm muscle strength. However, the results must be interpreted with caution because there were variations between the trials in the duration and amount of training, type of treatment, and in the patient characteristics.

[Rehabilitation with coronavirus disease with SARS-CoV-2 (COVID-19)]. / Rehabilitation bei Coronavirus-Erkrankung mit SARS-CoV-2 (COVID-19).

The Coronavirus disease with SARS-CoV-2 viral infection (COVID-19) and its diverse courses of disease from mild to critical illness frequently is not only an acute disease, but will - in a proportion of those affected - lead to organ structure and body function deficits that still exist or become apparent after the acute stage of disease.

An individual medical, frequently multi-professional diagnostic evaluation is mandatory in that situation: For adequate treatment, it is important to identify and objectify the individually underlying health conditions based on knowledge about the diverse potential consequences of COVID-19, to assess type and severity of functional consequences (impairments, activity limitations, and restrictions of participation) of Long-/Post-COVID individually, and then to decide on the treatment necessities and plans. With regard to rehabilitation, need and decision for either pulmonary, neurological, cardiac, or psychosomatic rehabilitation depends on the individual medical presentation.

Functional MRI in Radiology-A Personal Review.

We, here, provide a personal review article on the development of a functional MRI in the radiology departments of two German university medicine units. Although the international community for human brain mapping has met since 1995, the researchers fascinated by human brain function are still young and innovative. However, the impact of functional magnetic resonance imaging (fMRI) on prognosis and treatment decisions is restricted, even though standardized methods have been developed. The tradeoff between the groundbreaking studies on brain function and the attempt to provide reliable biomarkers for clinical decisions is large. By describing some historical developments in the field of fMRI, from a personal view, the rise of this method in clinical neuroscience during the last 25 years might be understandable. We aim to provide some background for (a) the historical developments of fMRI, (b) the establishment of two research units for fMRI in the departments of radiology in Germany, and (c) a description of some contributions within the selected fields of systems neuroscience, clinical neurology, and behavioral psychology.
