Cognitive dysfunction in post-COVID-19 condition: Mechanisms, management, and rehabilitation.

The long-term effects of COVID-19 on cognitive function have become an area of increasing concern. This paper provides an overview of characteristics, risk factors, possible mechanisms, and management strategies for cognitive dysfunction in post-COVID-19 condition (PCC). Prolonged cognitive dysfunction is one of the most common impairments in PCC, affecting between 17% and 28% of the individuals more than 12 weeks after the infection and persisting in some cases for several years. Cognitive dysfunctions can be manifested as a wide range of symptoms including memory impairment, attention deficit, executive dysfunction, and reduced processing speed. Risk factors for developing PCC, with or without cognitive impairments, include advanced age, preexisting medical conditions, and the severity of acute illness. The underlying mechanisms remain unclear, but proposed contributors include neuroinflammation, hypoxia, vascular damage, and latent virus reactivation not excluding the possibility of direct viral invasion of the central nervous system, illustrating complex viral pathology. As the individual variation of the cognitive impairments is large, a neuropsychological examination and a person-centered multidimensional approach are required. According to the World Health Organization, limited evidence on COVID-19-related cognitive impairments necessitates implementing rehabilitation interventions from established practices of similar conditions. Psychoeducation and compensatory skills training are recommended. Assistive products and environmental modifications adapted to individual needs might be helpful. In specific attention- and working memory dysfunctions, cognitive training-carefully monitored for intensity-might be effective for people who do not suffer from post-exertional malaise. Further research is crucial for evidence-based interventions specific to COVID-19-related cognitive impairments.

Survey of young patients with polio and a foreign background at a Swedish post-polio outpatient clinic.

Nowadays, polio survivors aged under 60 years are non-native Swedes which pose new aspects and challenges to a post-polio outpatient clinic. To analyze the medical data, walking aids, occupational, and family situation in non-native polio survivors aged less than 60 years at a Swedish post-polio outpatient clinic. Retrospective data analysis. Data were retrieved from medical records at the post-polio outpatient clinic. Actual age, age at acute polio infection, walking capacity, pain, concomitant diseases, working and family situation, and ethnical origin were analyzed. Data are presented in numbers and percentage. 153 patients were included. Mean age was 45 (17-60) years, and mean age at acute polio infection was 2 (0-12) years. Paresis of the lower extremities was the most common disability. 10 % were wheelchair dependent. Pain occurred in 70 % with a mean intensity of 55 measured with the visual analog scale. Hypertension was the most common concomitant disease. Half of the polio survivors were working at least part time, and roughly half were singles. Data were comparable with data earlier published in Swedish native polio survivors. Non-native polio survivors aged under 60 years showed similarities in age at acute polio infection, paresis, prevalence, and intensity of pain when compared with native Swedish polio survivors. They were, however, younger, and were less often working and married/cohabitants than native Swedish polio survivors. The results of this study underline the importance of social and vocational rehabilitation tailoring rehabilitation suitable for polio survivors with a foreign background.

Elevated blood lipids are uncommon in patients with post-polio syndrome--a cross sectional study.

BACKGROUND: The post-polio syndrome occurs in people who previously have had poliomyelitis. After the initial recovery, new or increasing neurologic symptoms occur. Inflammation and dyslipidaemia may play an important role in the development of atherosclerotic complications, for example myocardial infarction and angina pectoris. Previous studies on cardiovascular risk factors in the post-polio syndrome have found a higher prevalence of hypertension, ischemic heart disease, hyperlipidaemia, and stroke in these patients. The present study was undertaken in order to evaluate whether post-polio patients have elevated lipid values, and if blood lipid abnormalities could be correlated to signs of inflammation. METHODS: Cross-sectional study of 89 consecutive post-polio patients, (53 women, mean age 65 years) from the Post-Polio Outpatient Clinic, Danderyd University Hospital, Stockholm, Sweden. The lipid profiles of post-polio patients were compared to age and sex matched reference values from two earlier studies. Statistical analyses were performed by the Student's t-test, and linear regression analyses were assessed by Pearson's correlation coefficient. RESULTS: Mean total cholesterol levels (5.7 mmol/L) were low or normal in post-polio patients, whereas low density lipoprotein levels (3.6 mmol/L) were normal, and high density lipoprotein (1.5 mmol/L) and triglycerides (1.4 mmol/L) lower than reference values. The prevalence of diabetes (7%), hypertension (38%), concomitant cardiovascular disease, (including angina pectoris, myocardial infarction, heart failure, atrial fibrillation and stroke) (7%), and calculated 10 year risk of coronary heart disease according to Framingham risk score algorithm (8%) was not increased in post-polio patients. CONCLUSIONS: Compared to reference populations, post-polio patients in Sweden appear to have low or normal total cholesterol and low density lipoprotein levels, whereas high density lipoprotein and triglyceride levels are low. Hence, a possible persisting inflammatory process in post-polio syndrome does not seem to be associated with increased lipids and an increased risk for coronary heart disease events.

Immunoglobulin g for the treatment of chronic pain: report of an expert workshop.

BACKGROUND: The treatment of chronic pain is still unsatisfactory. Despite the availability of different drugs, most patients with chronic pain do not receive satisfactory pain relief or report side effects. Converging evidence implicates involvement of the immune system in the pathogenesis of different types of nociceptive and neuropathic chronic pain. DESIGN: At a workshop in Liverpool, UK (October 2012), experts presented evidence suggesting immunological involvement in chronic pain and recent data supporting the concept that the established immune-modulating drug, polyvalent immunoglobulin G (IgG), either given intravenously (IVIg) or subcutaneously (SCIg), may reduce pain in some peripheral neuropathies and a range of other pain disorders. Workshop's attendees discussed the practicalities of using IVIg and SCIg in these disorders, including indications, cost-effectiveness, and side effects. RESULTS: IgG may reduce pain in a range of nociceptive and neuropathic chronic pain conditions, including diabetes mellitus, Sjögren's syndrome, fibromyalgia, complex regional pain syndrome, post-polio syndrome, and pain secondary to pathological autoantibodies. CONCLUSIONS: IgG is a promising treatment in several chronic pain conditions. IgG is a relatively safe therapeutic strategy, with uncommon and mild side effects but high costs. Randomized, controlled trials and predictive tests are needed to better support the use of IgG for refractory chronic pain.

Post-polio syndrome - somatosensory dysfunction and its relation to pain: a pilot study with quantitative sensory testing.

OBJECTIVE: To explore and characterize somatosensory dysfunction in patients with post-polio syndrome and chronic pain, by conducting examinations with Quantitative Sensory Testing. DESIGN: A cross-sectional, descriptive, pilot study conducted during 1 month. SUBJECTS/PATIENTS: Six patients with previously established post-polio syndrome and related chronic pain. METHODS: All subjects underwent a neurological examination including neuromuscular function, bedside sensory testing, a thorough pain anamnesis, and pain drawing. Screening for neuropathic pain was done with 2 questionnaires. A comprehensive Quantitative Sensory Testing battery was conducted with z-score transformation of obtained data, enabling comparison with published reference values and the creation of sensory profiles, as well as comparison between the study site (more polio affected extremity) and internal control site (less affected extremity) for each patient. RESULTS: Derived sensory profiles showed signs of increased prevalence of sensory aberrations compared with reference values, especially Mechanical Pain Thresholds, with significant deviation from reference data in 5 out of 6 patients. No obvious differences in sensory functions were seen between study sites and internal control sites. CONCLUSION: Post-polio syndrome may be correlated with a mechanical hyperalgesia/allodynia and might be correlated to a somatosensory dysfunction. With lack of evident side-to-side differences, the possibility of a generalized dysfunction in the somatosensory system might be considered.

Vision impairment is common in non-hospitalised patients with post-COVID-19 syndrome.

CLINICAL RELEVANCE: Vision-related problems can be part of longstanding sequelae after COVID-19 and hamper the return to work and daily activities. Knowledge about symptoms, visual, and oculomotor dysfunctions is however scarce, particularly for non-hospitalised patients. Clinically applicable tools are needed as support in the assessment and determination of intervention needs. BACKGROUND: The purpose of this study was to evaluate vision-related symptoms, assess visual and oculomotor function, and to test the clinical assessment of saccadic eye movements and sensitivity to visual motion in non-hospitalised post-COVID-19 outpatients. The patients (n = 38) in this observational cohort study were recruited from a post-COVID-19 clinic and had been referred for neurocognitive assessment. METHODS: Patients who reported vision-related symptoms reading problems and intolerance to movement in the environment were examined. A structured symptom assessment and a comprehensive vision examination were undertaken, and saccadic eye movements and visual motion sensitivity were assessed. RESULTS: High symptom scores (26-60%) and prevalence of visual function impairments were observed. An increased symptom score when reading was associated with less efficient saccadic eye movement behaviour (p < 0.001) and binocular dysfunction (p = 0.029). Patients with severe symptoms in visually busy places scored significantly higher on the Visual Motion Sensitivity Clinical Test Protocol (p = 0.029). CONCLUSION: Vision-related symptoms and impairments were prevalent in the study group. The Developmental Eye Movement Test and the Visual Motion Sensitivity Clinical Test Protocol showed promise for clinical assessment of saccadic performance and sensitivity to movement in the environment. Further study will be required to explore the utility of these tools.

Improved Functioning and Activity According to the International Classification of Functioning and Disability after Multidisciplinary Telerehabilitation for Post-COVID-19 Condition-A Randomized Control Study.

This study investigates the outcomes and feasibility concerning the functioning and activity of multidisciplinary group telerehabilitation for a post-COVID-19 condition. Recruitment for the group rehabilitation was announced three times during 2021 and 2022 through the COVID-19 patient organization in Sweden. The key inclusion criteria were remaining symptoms and functional impairments beyond 12 weeks after SARS-CoV-2 infection; medical assessment and treatment regarding comorbidities or new postinfection symptoms; the ability to use the Internet. Participants were randomized into a rehabilitation group or onto a waiting list using an Internet program. Multiple outcomes included self-scored questionnaires and physical tests before and after eight weeks, and at six months follow-up. Here, we present the self-scored outcomes on the International Classification of Functioning and Disability questionnaire (ICF, 22 body functions and 16 activity/participation categories) and breathing scales. Of the 164 participants who registered for the study, 67 (mean age 43, 78% women) participated in an eight-week group rehabilitation compared to 42 who served as waiting list controls (mean age 47, 88% women). At six months follow-up, 60 participants from the rehabilitation group and 21 from the waiting list completed the data. The results indicate that a larger number of ICF body functions and activity/participation categories had improved in the rehabilitation group after eight weeks and six months. Overall credibility, as assessed by the Credibility Expectancy Questionnaire, was high, and the attrition rate in rehabilitation was low. The results indicate beneficial outcomes for multidisciplinary telerehabilitation in people suffering from a post-COVID-19 condition. Therefore, rehabilitation interventions should be further developed and implemented in clinical practice.

Interdisciplinary pain rehabilitation for immigrants with chronic pain who need language interpretation.

OBJECTIVE: To investigate outcomes in patients with chronic pain after participation in an interdisciplinary pain rehabilitation programme with language interpreters, and to investigate the outcomes in women and men separately. DESIGN: Prospective multi-centre cohort study. PATIENTS: Ninety-five patients in Sweden with chronic pain who have insufficient knowledge of the Swedish language. METHODS: Duration and intensity of pain, anxiety and depression, health-related quality of life and fear of movement were evaluated before and after the programme. Patients were compared with a reference group comprising Swedish-speaking patients participating in an ordinary interdisciplinary pain rehabilitation programme. RESULTS: Before the interdisciplinary pain rehabilitation programme with language interpreters, all variables except pain duration differed significantly to the detriment of the studied group. The studied group showed significant improvements after the interdisciplinary pain rehabilitation programme with language interpreters, with regards to pain intensity, depression and fear of movement. The reference group improved significantly for all variables. The women in the studied group showed significant improvements for the same variables as the whole group, while the men in the studied group did not improve in any of the variables. CONCLUSION: This study indicates that patients with chronic pain, and especially women, who have insufficient knowledge of Swedish seem to benefit from participating in an interdisciplinary pain rehabilitation programme with language interpreters. The result may be of value for the further development of rehabilitation programmes with language interpreters.

The risk of post-polio syndrome among immigrant groups in Sweden.

To examine the risk of post-polio syndrome (PPS) in immigrant groups using native Swedish-born individuals as referents. This is a retrospective study. The study population included all individuals aged 18 years and older registered in Sweden. PPS was defined as having at least one registered diagnosis in the Swedish National Patient Register. The incidence of post-polio in different immigrant groups, using Swedish-born individuals as referents, was assessed by Cox regression, with hazard ratios (HRs) and 99% confidence intervals (CI). The models were stratified by sex and adjusted for age, geographical residence in Sweden, educational level, marital status, co-morbidities, and neighbourhood socioeconomic status. In total 5300 post-polio cases were registered, 2413 males and 2887 females. Fully adjusted HRs (99% CI) in immigrants versus Swedish-born were 1.77 in men (1.52-2.07) and 1.39 (1.19-1.62) in women. Statistically significant excess risks of post-polio were found in the following subgroups: men and women from Africa, HRs (with 99% CI) 7.40 (5.17-10.59) and 8.39 (5.44-12.95), respectively, and Asia, HRs 6.32 (5.11-7.81) and 4.36 (3.38-5.62) respectively, and in men from Latin America, HR 3.66 (2.17-6.18). It is of importance to be aware of risks of PPS in immigrants settled in Western countries, and that it is more common in immigrants from regions of the world where polio is still prevalent. Patients with PPS need treatment and proper follow-up until polio has been eradicated through global vaccination programs.

Study protocol for a randomized, controlled, multicentre, pragmatic trial with Rehabkompassen®-a digital structured follow-up tool for facilitating patient-tailored rehabilitation in persons after stroke.

BACKGROUND: Stroke is a leading cause of disability among adults worldwide. A timely structured follow-up tool to identify patients' rehabilitation needs and develop patient-tailored rehabilitation regimens to decrease disability is largely lacking in current stroke care. The overall purpose of this study is to evaluate the effectiveness of a novel digital follow-up tool, Rehabkompassen®, among persons discharged from acute care settings after a stroke. METHODS: This multicentre, parallel, open-label, two-arm pragmatic randomized controlled trial with an allocation ratio of 1:1 will be conducted in Sweden. A total of 1106 adult stroke patients will have follow-up visits in usual care settings at 3 and 12 months after stroke onset. At the 3-month follow-up, participants will have a usual outpatient visit without (control group, n = 553) or with (intervention group, n = 553) the Rehabkompassen® tool. All participants will receive the intervention at the 12-month follow-up visit. Feedback from the end-users (patient and health care practitioners) will be collected after the visits. The primary outcomes will be the patients' independence and social participation at the 12-month visits. Secondary outcomes will include end-users' satisfaction, barriers and facilitators for adopting the instrument, other stroke impacts, health-related quality of life and the cost-effectiveness of the instrument, calculated by incremental cost per quality-adjusted life year (QALY). DISCUSSION: The outcomes of this trial will inform clinical practice and health care policy on the role of the Rehabkompassen® digital follow-up tool in the post-acute continuum of care after stroke. TRIAL REGISTRATION: ClinicalTrials.gov NCT04915027. Registered on 4 June 2021. ISRCTN registry ISRCTN63166587. Registered on 21 August 2023.

Preliminary Findings on Cognitive Dysfunction in University-Educated Patients After Mild COVID-19 Disease.

Objective: To investigate cognitive functioning in patients with higher education having post COVID-19 condition. Design: Prospective cohort study. Setting: Outpatient rehabilitation clinic. Participants: Patients (N=38; mean age, 48.5y; 71% women) at the Cognitive Post COVID-19 Clinic at Danderyd University Hospital in Stockholm, Sweden, who sought health care because of self-experienced cognitive problems. All had at least 4 years of university education and an initially mild infection (ie, most were not hospital admitted, none were admitted to intensive care). Interventions: Not applicable. Main Outcome Measures: Cognitive test performance assessed with a comprehensive neuropsychological test battery including Information, Matrix Reasoning, Coding, and Digit Span from Wechsler's Adult Intelligence Scale-IV, Buschke Selective Reminding Test, Rey Complex Figure Test, Ruff 2&7, Color-Word Interference Test, Verbal Fluency, and Trail Making Test. The mean time between the infection and the assessment was 18 months. Results: Cognitive deficits were evident on tests of verbal learning and memory (Buschke Selective Reminding Test) and selective attention (Ruff 2&7). Approximately 50% of the participants had scores lower than 1 SD below the mean in the norm group on the measures of verbal learning and memory. When estimated premorbid cognitive functioning was accounted for, deficits were suggested in most cognitive domains. Conclusions: Post COVID-19 condition seems to be associated with cognitive deficits, even in patients with high education and an initially mild infection.

Intravenous immunoglobulin treatment of the post-polio syndrome: sustained effects on quality of life variables and cytokine expression after one year follow up.

BACKGROUND: Expression of inflammatory cytokines in cerebrospinal fluid (CSF) has led to the hypothesis of intrathecal chronic inflammation to explain the denervation observed in post-polio syndrome (PPS). It has been shown that therapy with intravenous immunoglobulin (IVIG) improves physical performance and dampens down the inflammatory process at 6 months in PPS patients. We here examined the effects of IVIG on cytokine expression and clinical outcome one year after IVIG treatment. METHODS: From a previous study with 135 PPS patients included, 41 patients were further evaluated before un-blinding for one year (21 placebo and 20 treated with IVIG, Xepol® 50 mg/ml), and were assessed for clinical variables by performing the Short Form-36 survey (SF-36) questionnaire assessment, the 6 minute walk distance test (6MWT) and registering pain level by Visual Analogue Scale (VAS) after IVIG treatment. A separate cohort of 37 PPS patients went through lumbar puncture (LP) at baseline and 20 patients, treated with IVIG, repeated the LP one year later. Thirty patients affected with other neurological diseases (OND) were used as control group. Inflammatory cytokines TNF, TGFß, IFNγ, IL-23, IL-13 and IL-10 were measured in blood cells and CSF cells with RT-PCR. RESULTS: Scores of the physical components of SF-36 were significantly higher at the one year follow up time-point in the IVIG-treated patients when compared to baseline as well as to the control subjects. Pain VAS score and 6MWT improved significantly in the IVIG-treated patients when compared with baseline Relative expression of TNF and IFN-γ in both PBMCs and CSF from PPS patients were increased compared to OND subjects at baseline (p < 0.05). One year after IVIG-treatment a decreased expression of IFN-γ and IL23 was found in CSF of PPS patients, while anti-inflammatory IL-13 was increased (p < 0.05). CONCLUSIONS: IVIG has effects on relevant QoL variables and inflammatory cytokines up to one year in patients with PPS. This gives a basis for scheduling IVIG in upcoming trials with this therapy.

Effects of immunosuppressive treatment on interleukin-15 and interleukin-15 receptor α expression in muscle tissue of patients with polymyositis or dermatomyositis.

OBJECTIVES: To investigate the expression of interleukin (IL)-15 and IL-15 receptor α (IL-15Rα) in muscle tissue from patients with polymyositis or dermatomyositis before and after conventional immunosuppressive (IS) treatment. METHODS: Muscle biopsies from 17 patients before and after conventional IS treatment and seven healthy individuals were investigated by immunohistochemistry using antibodies against IL-15 and IL-15Rα. Quantification was performed by computerised image analysis. Cellular localisation of IL-15 was determined by double immunofluorescence. Clinical outcome was measured by the functional index and serum creatine kinase. Human myotubes were cultured and IL-15 staining was performed by immunocytochemistry. RESULTS: IL-15 was observed in mononuclear inflammatory cells of muscle tissue while IL-15Rα was localised to mononuclear inflammatory cells, capillaries and large vessels. Double staining showed localisation of IL-15 to CD163+ macrophages. A significantly larger number of IL-15 and IL-15Rα-positive cells were seen in muscle tissue of patients compared with healthy individuals. Baseline IL-15 expression correlated negatively with improvement in muscle function. After conventional IS treatment, a significantly lower number of IL-15 and IL-15Rα-positive cells was found. However, compared with controls, eight of 17 patients still had more IL-15-positive cells and less muscle function improvement was shown in this group of patients, both in short-term and long-term observations. Human differentiated myotubes were negative for IL-15 staining. CONCLUSIONS: IL-15 and its receptor are expressed in the muscle tissue of patients with myositis and IL-15 expression is correlated with improvement in muscle function. IL-15 may play a role in the pathogenesis of myositis and could be a biological treatment target, at least in a subgroup of patients with polymyositis or dermatomyositis.

PAIN IN POST-POLIO SYNDROME: A SEPARATE PAIN ENTITY?

BACKGROUND: Most patients with polio recover from the initial infection, but develop muscle weakness, pain and fatigue after 15-40 years, a condition called post-polio syndrome. Although poliovirus has been almost eliminated, 12-20 million people worldwide still have polio sequelae. The pain is described mainly as nociceptive, but some patients experience neuropathic pain. The aim of this study was to further characterize post-polio pain. PATIENTS AND METHODS: A total of 20 patients with post-polio syndrome participated in the study. Physical examination was performed, and questionnaires containing pain drawing and visual analogue scales (VAS) for pain intensity during rest and motion and VAS for fatigue were completed. A walk test was performed to evaluate physical performance. RESULTS: Pain intensity was high (42/100 on the VAS at rest and 62/100 while moving). The pain was localized in both joints and muscles. Pain in the muscles was of "deep aching" character, included "muscle cramps" and was located mainly in polio-weakened limbs. CONCLUSION: Muscle pain in patients with post-polio syndrome does not fulfil the criteria for either nociceptive or neuropathic pain; thus, it is suggested that the pain is termed "post-polio muscular pain". The intensity of post-polio muscular pain is higher while moving, but does not influence physical function, and is separate from fatigue.

Pain Burden in Post-COVID-19 Syndrome following Mild COVID-19 Infection.

The global pandemic of SARS-CoV-2 has affected several hundred million people, and many infected people have suffered from a milder initial infection but have never fully recovered. This observational study investigates the pain burden in sufferers of post-COVID-19 syndrome after a milder initial infection. One hundred post-COVID-19 patients filled out questionnaires regarding sociodemographic data, previous comorbidities, present pharmacological treatment, pain intensity and pain localisation. Health-related quality of life, fatigue, emotional status, and insomnia were measured by validated questionnaires. Multiple post-COVID-19 symptoms, including post-exertional malaise, were evaluated by a symptom questionnaire. Among the 100 participants (mean age 44.5 years), 82% were women, 61% had higher education, and 56% were working full or part time. Nine participants reported previous pain or inflammatory conditions. Among the most painful sites were the head/face, chest, lower extremities, and migrating sites. Generalised pain was self-reported by 75 participants and was estimated in 50 participants. Diagnosis of fibromyalgia according to the 2016 criteria was suspected in 40 participants. Subgroup analyses indicated that comorbidities might play a role in the development of pain. In conclusion, a major part of sufferers from post-COVID-19 syndrome develop pain, and in addition to its many disabling symptoms, there is an urgent need for pain management in post-COVID-19 syndrome.

Plasma levels of S100B and neurofilament light chain protein in stress-related mental disorders.

The pathophysiological changes underlying stress-related mental disorders remain unclear. However, research suggests that alterations in astrocytes and neurons may be involved. This study examined potential peripheral markers of such alterations, including S100B and neurofilament light chain (NF-L). We compared plasma levels of S100B and NF-L in patients with chronic stress-induced exhaustion disorder (SED), patients with major depressive disorder (MDD), and healthy controls. We also investigated whether levels of S100B and NF-L correlated with levels of astrocyte-derived extracellular vesicles (EVs that indicate astrocyte activation or apoptosis) and with symptom severity. Only women had measurable levels of S100B. Women with SED had higher plasma levels of S100B than women with MDD (P < 0.001) and healthy controls (P < 0.001). Self-rated symptoms of cognitive failures were positively correlated with levels of S100B (rs = 0.434, P = 0.005) as were depressive symptoms (rs = 0.319, P < 0.001). Plasma levels of astrocyte-derived EVs were correlated with levels of S100B (rs = 0.464, P < 0.001). Plasma levels of NF-L did not differ between the groups and were not correlated with symptom severity or EV levels. Thus, long-term stress without sufficient recovery and SED may be associated with raised plasma levels of S100B, which may be evidence of pathophysiological changes in astrocytes. The findings also support the hypothesis that plasma levels of S100B are associated with cognitive dysfunction.

Evidence-based position paper on Physical and Rehabilitation Medicine practice for people with amyotrophic lateral sclerosis.

Amyotrophic lateral sclerosis (ALS) is a progressive motor neuron disease that affects both upper and lower motor neurons and is fatal in its course. This evidence-based position paper represents the official position of the UEMS PRM Section. The aim of the paper is to define the role of the physical and rehabilitation medicine (PRM) physician and PRM professional practice for people with ALS. A systematic review of the literature and a consensus procedure by means of a Delphi process have been performed involving the delegates of all European countries represented in the UEMS PRM Section. The systematic literature review is reported together with thirty-two recommendations resulting from the Delphi procedure. The responsibility of the PRM physician is functional assessment of persons with ALS and delivering the optimal and most effective PRM program of care. The rehabilitation program of patients with ALS should be delivered and monitored by the multiprofessional team, with the PRM physician as principal coordinator.

Self-scored impairments in functioning and disability in post-COVID syndrome following mild COVID-19 infection.

OBJECTIVES: To investigate functioning, activity and disability in people with post-COVID syndrome. DESIGN: Cross-sectional. SUBJECTS/PATIENTS: Participants were recruited online via Facebook and a stakeholders' organization for post-COVID syndrome in Sweden. METHODS: Sociodemographic data and International Classification of Functioning, Disability and Health (ICF)-based questionnaire were collected via an online platform and analysed. RESULTS: A total of 100 participants were included (mean age 44.5 years, 82% women, 61% with higher education, and 56% working full- or part-time). For the ICF component Body Functions, the most impaired functions were: fatigability and energy drive (98-99%); higher cognitive functions (74-94%); sleep functions (98%); muscle functions (93%); respiratory functions (92%); heart functions (82%); emotional functions (80%); sexual functions (77%); pain problems (56-90%); and thermoregulatory functions (68%). For the component Activity, the most frequent limitations were: handling stressful situations (98%); remunerative employment (95%); recreation and leisure (94%); climbing the stairs (94%); doing housework (84%); and informal socializing (64%). The most frequent degrees of impairment/limitations were light and moderate, except for severe-complete for fatigue, higher cognitive functions, multitasking, handling stressful situations; and recreation and leisure activities. CONCLUSION: Post-COVID syndrome following a mild COVID-19 infection can result in impaired body functions and activities. These results support the importance of a multidisciplinary rehabilitation approach for these patients.

Tolerability and psychological effects of a multimodal day-care rehabilitation program for persons with Huntington's disease.

OBJECTIVE: To determine whether the psychological benefits of intense, inpatient, multimodal rehabilitation for persons with Huntingtons disease (HD), as found in earlier studies, also apply in a shorter, day-care setting. DESIGN: Prospective, non-randomized cohort study. SUBJECTS: Twenty patients attending a group-based 8-week (3 days/week) rehabilitation programme aimed at persons in early stages of HD. METHODS: An explorative cohort study on register data from a specialized rehabilitation centre, includ-ing descriptive data, number of cancellations, a self-reported evaluation, and measures of psychiatric symptoms, health-related quality of life, sense of coherence and physical function at baseline and at the end of rehabilitation. RESULTS: Patients' attendance rate was almost 90%. Patients were satisfied, and displayed significantly reduced anxiety and depression and improved health-related quality of life after rehabilitation. Baseline measures of sense of coherence showed significant negative correlation with the number of cancelled days of rehabilitation. Physical function improved, but did not correlate significantly with psychological outcome measures. CONCLUSION: These results indicate that an 8-week multimodal day-care rehabilitation programme can be tolerable, reduce psychiatric symptoms, and improve health-related quality of life for people with HD. A higher sense of coherence seems to promote attendance rates. Further larger studies, including the impact of cognition and disease progression on the treatment effect, are warranted.
