ABSTRACT
The COVID-19 pandemic has an impact on people's ability to exercise and walk. Decreased ex-ercise habit leads to decreased muscle mass, which may hamper social activities. The decline in exercise habit is a particular challenge among older people, as it may lead to frailty. In this paper, we report that creating arches at the cuboid boneand adductor muscles activates toe movement. We examined whether the arches could be built into shoe insole to correct left-right differences in leg skeletal muscle mass. A prototype insole with arches created at the cuboid boneand transverse head of adductor hallucis musclewas designed, and a prospec-tive cohort study was conducted to examine its effects. Plantar pressure during walking was recorded in 10 sub-jects, and a 3-month intervention study was conducted in 40 subjects. The results showed an increase in toe pressure from before to after wearing the prototype insoles. In addition, leg skeletal muscle mass increased in the group wearing the prototype insole, and a significant difference compared to the control group was detect-ed by Wilcoxon signed-rank test. The results from this study demonstrate that the prototype insole promotes toe movement and increases leg skeletal muscle mass.
ABSTRACT
BackgroundHypophosphatasia(HPP), a rare, inherited metabolic disease featuring low serum alkaline phosphatase (ALP) activity due to ALPL (encoding tissue non-specific alkaline phosphatase) gene mutation[1,2]. A wide-ranging clinical spectrum is often seen due to defective mineralisation affecting teeth, bones, joints and muscles[1]. This disease has a prevalence of 1/6370 in Europe and is often misdiagnosed and underdiagnosed with a diagnostic delay of more than ten years[1] The treatment is often supportive for milder cases and enzyme replacement therapy in severe cases.ObjectivesTo share this case to raise awareness among Rheumatologists.MethodsThis 58-year-old Caucasian female had her first HPP symptom as early eruption of deciduous teeth, along with recurrent dental infections and gum problems. She was diagnosed with flat feet at age five, had a big toe fracture at sixteen, followed by a metatarsal fracture. She experienced leg muscle cramps and aches, affecting her performance in sport during school life.At the age of thirty she began noticing weakness in arms and legs, which progressed over the years. She faced significant early morning stiffness along with painful ribs, hips, knees, shoulders, and small joints of feet when walking.She was diagnosed with Fibromyalgia at the age of forty-four. The following ten years she met numerous specialists including rheumatologist, pain specialist and physiotherapists. She was also diagnosed with early osteoarthritis, pernicious anaemia, hyperlipidemia, functional neurological syndrome, and central sensitization syndrome. She had multiple trials of steroids and opioids, all of which were stopped either due to side effects or inefficiency.A major flare of symptoms five years ago rendered her bedbound for three months, following which a chemical pathologist noticed a persistent low ALP levels and decided to investigate for HPP. It took another four years to complete these investigations due to the coronavirus pandemic.Currently, she is unable to weight bear or climb stairs and must stay indoors or in bed during flareup. She moved into a ground floor flat at the age of 54 and use a walking stick occasionally. By 58, she is unable to work and had given up her own business due to pain, weakness, and disability.ResultsOn clinical assessment, her height is 160 cm, faced difficulty getting up from chair, has an antalgic waddling gait, with a 6-minute walking distance of 60 metre, stopped after three minutes, and had a Brief Pain Inventory pain severity score of 7/10. Her ALP level is 24 U/L and PLP/PA ratio is 18.8 (ref < 5), and genetic testing showed heterozygous missense variant of ALPL gene mutation.ConclusionIt took more than forty years to reach a conclusive diagnosis of childhood onset HPP. Low ALP level is a signature of HPP and warrants investigations. Diagnosis can be challenging due to the rareness and variable presentation, however recognition of HPP features is crucial for timely referral, optimal disease management and potential improvement in quality of life.References[1]Högler W, Langman C, Gomes da Silva H, Fang S, Linglart A, Ozono K, Petryk A, Rockman-Greenberg C, Seefried L, Kishnani PS.

ABSTRACT
BackgroundChronic low back pain is a very common problem worldwide. Reasons such as repetitive problems and lack of a clear treatment cause low back pain to be a serious burden for society [1]. Telerehabilitation provides remote application of rehabilitation services with the developing technology. Especially in the COVID-19 pandemic, the problems experienced in health services have increased the popularity of telerehabilitation services [2].ObjectivesAim in this study is to investigate the effects of spinal stabilization exercises performed remotely with asynchronous video clips on pain, disability, quality of life, trunk flexion range of motion and gait parameters.MethodsA total of 20 individuals with chronic low back pain were included in the study. After recording demographic information, pain levels were evaluated with the Visual Analogue Scale (VAS), disability levels were evaluated with the Oswestry Disability Index (ODI), and quality of life was evaluated with the Nottingham Health Profile (NHP). Trunk flexion range of motion was evaluated with the Valedo ® system (Hocoma, Switzerland), and the spatiotemporal parameters of the gait (step time, cadance) were evaluated with the OPTOGAIT system (OPTOGait, Microgate, Italy). After the evaluation, the individuals were divided into 2 groups. One group did face-to-face progressive spinal stabilization exercises in the clinic, while the other group did the same exercise program remotely with asynchronous videos. The exercise program was 8 weeks, 3 days a week.ResultsThe mean age of the telerehabilitation group (4 M, 5 F) was 41.44 ± 9.74, and their body mass index (BMI) was 26.34 ± 3.1. The mean age of the clinical group (1 M, 8 F) was 41.0 ± 13.0, and their BMI was 27.64 ± 3.55. All parameters were similar in the two groups before treatment. There was a significant difference in parameters except gait parameters in both groups after treatment (p<0.05). In the evaluation between the groups after treatment, the results of the two groups were similar in all parameters (p>0.05) (Table 1).Table 1.Baseline and after treatment characteristics of telerehabilitation and face to face group and comparison of with-in group and between groupTelerehabilitationFace to FaceBaselineAfter Treatmentp valueBaselineAfter Treatmentp valueBetween GroupVAS6.51±1.612.41±1.170.00*6.62±0.952.33±1.980.00*0.79ODI20.66±9.9413.55±100.00*30.22±15.517.11±120.02*0.54NHP131.51±121.2934.0±29.610.01*203.55±60.0763.08±76.240.00*0.66Trunk Flexion Range of Motion99.55±12.24106.55±7.510.04*88.11±15.2694.11±15.180.00*0.09Step length (cm)60.67±9.0764.35±9.580.5153.82±2165.95±9.410.170.54Step Time (sec)0.55±0.040.51±0.080.260.40±0.120.34±0.180.130.06Cadance105.67±9.17106.13±17.460.44103.37±8.64105.31±9.450.670.73ConclusionAccording to the results of our study, it is seen that both methods did not provide any change in gait parameters. However, it has similar effects in reducing pain and disability, improving quality of life, and increasing trunk range of motion. For individuals with chronic low back pain, it seems that remote exercise with asynchronous videos can be as effective a treatment as face-to-face exercise. There is a need for studies to be conducted in a larger population with longer follow-up.References[1] Anderson GB. epidemiological features of chronicles low back pain _ the lance _ 1999;354(9178):581-5.[2] Turolla A, Rossettini G, Viceconti A, Palese A, Geri T.

ABSTRACT
A "Stroke" is a neurological disease due to poor blood flowing to the brain, resulting in body cell death. It is ranked second as the most common cause of death globally. The "World Health Organization" estimates that about 15 million people suffer a stroke annually. Most stroke survivors have gait disorders, and most patients cannot walk without assistance. Physiotherapy is crucial for stroke patients to recover and maintain their mobility, functionality, and well-being. In the last 20 years, the replacement of physiotherapists with wearable robotics has become essential due to the developing technology, the need for economic growth, and the challenging health circumstances around the world, such as the COVID-19 pandemic recently. Lower Limb Exoskeleton (LLE) represents the solution for stroke patients under such circumstances, though its performance is a critical challenge paid attention to in the industry. This challenge has motivated the researchers to investigate the application of gait rehabilitation. This review presents and discusses the developments in the control system of LLE over the last decade. It also explores the limitations, new directions, and recommendations in LLE development according to the literature.
ABSTRACT
BACKGROUND: During the COVID-19 pandemic, rehabilitation providers and consumers adopted telehealth practices at unprecedented rates. Multiple prepandemic studies demonstrate the feasibility and comparable efficacy between in-clinic and remote treatment for certain impairments caused by stroke, such as upper extremity weakness and impaired motor function. However, less guidance has been available regarding gait assessment and treatment. Despite this limitation, safe and effective gait treatment is fundamental to optimizing health and well-being after stroke and should be considered a treatment priority, including during the COVID-19 pandemic. OBJECTIVE: This study explores the feasibility of using telehealth to deliver gait treatment using a wearable gait device, the iStride device, to stroke survivors during the 2020 pandemic. The gait device is used to treat hemiparetic gait impairments caused by stroke. The device alters the user's gait mechanics and creates a subtle destabilization of the nonparetic limb; therefore, supervision is required during its usage. Before the pandemic, treatment with the gait device had been provided in person to appropriate candidates using a combination of physical therapists and trained personnel. However, upon the emergence of the COVID-19 pandemic, in-person treatment was halted in adherence to pandemic guidelines. This study investigates the feasibility of 2 remote delivery treatment models with the gait device for stroke survivors. METHODS: Participants were recruited during the first half of 2020 after the onset of the pandemic and included 5 individuals with chronic stroke (mean age 72 years; 84 months post stroke). Four participants were previous gait device users who transitioned to the telehealth delivery model to continue their gait treatment remotely. The fifth participant performed all study-related activities, from recruitment through follow-up, remotely. The protocol included virtual training for the at-home care partner, followed by 3 months of remote treatment with the gait device. Participants were instructed to wear gait sensors during all treatment activities. To assess feasibility, we monitored the safety of the remote treatment, compliance with protocol activities, acceptability of the telehealth treatment delivery, and preliminary efficacy of the gait treatment. Functional improvement was measured using the 10-Meter Walk Test, the Timed Up and Go Test, and the 6-Minute Walk Test, and quality of life was assessed using the Stroke-Specific Quality of Life Scale. RESULTS: No serious adverse events occurred, and participants rated high acceptance of the telehealth delivery. Protocol compliance averaged 95% of treatment sessions, 100% of assessments, and 85% of sensor usage during treatment. After 3 months of treatment, the average improvement in each functional outcome exceeded the minimal clinically important difference or minimal detectable change value. CONCLUSIONS: Remote treatment delivery with the gait device appeared feasible with care partner support. Gait treatment using telehealth may be useful to offset negative immobility impacts for those requiring or preferring remote care during the pandemic or otherwise.

ABSTRACT
This paper reports the architecture of a low-cost smart crutches system for mobile health applications. The prototype is based on a set of sensorized crutches connected to a custom Android application. Crutches were instrumented with a 6-axis inertial measurement unit, a uniaxial load cell, WiFi connectivity, and a microcontroller for data collection and processing. Crutch orientation and applied force were calibrated with a motion capture system and a force platform. Data are processed and visualized in real-time on the Android smartphone and are stored on the local memory for further offline analysis. The prototype's architecture is reported along with the post-calibration accuracy for estimating crutch orientation (5° RMSE in dynamic conditions) and applied force (10 N RMSE). The system is a mobile-health platform enabling the design and development of real-time biofeedback applications and continuity of care scenarios, such as telemonitoring and telerehabilitation.

Case Report: Since the beginning of the Coronavirus Disease 2019 (COVID-19) pandemic, there has been much work to understand the negative effects of SARS-CoV-2 on tissues expressing the Angiotensin Converting Enzyme-2 (ACE2) receptor, including the placenta. However, there is limited information regarding placental pathology findings in mothers with COVID-19 and the effects of SARS-CoV-2 on the placenta. The available research reports effects on the fetus ranging from minimal to intrauterine fetal demise. Case Description: A 4680g baby boy was born at 38+1 weeks of gestation to 36y old G4P1021 female via repeat cesarian section. The pregnancy was complicated by advanced maternal age, chronic hypertension with superimposed pre-eclampsia with severe features, BMI of 80, and SARS-CoV-2 infection. The mother had mild COVID-19 symptoms and did not require hospitalization or oxygen support. Prenatal ultrasounds were limited due to body habitus. At the time of delivery, there was clear amniotic fluid. Upon delivery the infant was cyanotic and limp and was brought to the warmer immediately. Non-invasive positive pressure ventilation was initiated at 5 minutes of life with improvement in infant color and oxygen saturation. He was then admitted to the Neonatal Intensive Care Unit (NICU). APGARs were 2, 3, 5, and 7 at 1, 5, 10, and 15 minutes respectively. Cord gases showed severe metabolic acidosis. The patient was diagnosed with hypoxic-ischemic encephalopathy (HIE) and therapeutic hypothermia was initiated. Both the NICU and obstetric teams were unable to identify a clear perinatal cause of HIE in this patient. Later, the placenta pathology report revealed a large placenta for estimated gestational age corresponding to the 75th percentile, villous parenchyma with focal chorangiosis and thrombi, with unremarkable fetal membrane and three vessel umbilical cord. The cause of HIE was then thought to be due to the placental thrombi likely caused by SARS-CoV-2 infection. Discussion(s): Fetal vascular malperfusion and fetal vascular thrombus have been noted as a common finding in the placentas of pregnant women who test positive for SARS-CoV-2. There are various causes of HIE, from maternal, placental and fetal factors. This patient had no clinically evident hypoxic event, but information was limited due to the lack of monitoring of the fetus in utero. Given the mother's SARS-CoV-2 infection and the placental pathology findings, it is likely that the cause of this patient's HIE was related to the effects on the placenta from SARS-CoV-2. Conclusion(s): As more information comes to light about the effects of SARS-CoV-2 on the placenta, it is important to consider a maternal SARS-CoV-2 infection during pregnancy as a cause of HIE in a newborn.
ABSTRACT
Background: Sydenham chorea, or rheumatic chorea, is a movement disorder that is more prevalent among young people, with a mean age at symptom onset between 8 and 9 years. The condition is more common in females. Sydenham chorea is associated with rheumatic fever and is considered the most common cause of acute chorea in children. We believe that the present case is worth reporting since the occurrence of Sydenham chorea as a post-COVID-19 sequela has not been described in Brazil. Case Presentation: We report here the case of a 14-year-old girl with symptoms of acute chorea that emerged 15 days after treatment resolution of COVID-19 (SARS-CoV-2 or severe acute respiratory syndrome coronavirus 2). Brain computed tomography (CT) and magnetic resonance imaging scans showed no changes, and the laboratory tests revealed no signs of an active infectious process. In contrast, neurological positron-emission tomography/CT showed mild glycolytic hypometabolism in the bilateral mesial frontal region. Administration of an oral anticonvulsant resulted in a marked improvement in her symptoms. Conclusion(s): Despite major efforts of the scientific community for discovering treatments, preventive methods, mechanisms of action, and possible sequelae of SARS-CoV-2, there is still a long way to go to better understand this devastating pathological agent that has affected the global population.Copyright © 2023 Camargo and Morcillo.

ABSTRACT
Outcomes: 1. Utilizing CRISIS approach, participants can employ a unique strategy to holistically support patients with poor coping in an acute life-threatening situation. 2. Utilizing the CRISIS approach, participants will apply an ethical tool to mitigate the incongruence that sometimes happens between two ethical principles-autonomy versus beneficence. Autonomy is not always in harmony with beneficence. We present a patient with decisional capacity hospitalized with acute reversible neuromuscular paralysis who refused treatment despite expected recovery. Her decision created moral distress for the clinicians. An improvised palliative strategy resolved the above dilemma. Case presentation: 68-year-old female admitted with new-onset unsteady gait, diplopia, and speech impairment on waking up. She was healthy until 3 weeks before admission, when she developed upper extremity numbness progressing to both legs after a COVID-19 infection. She had bulbar and axial muscle weakness and right oculomotor nerve palsy with ptosis. Positive ice pack and pyridostigmine test indicated myasthenia gravis (MG). During hospitalization, she required mechanical ventilation secondary to acute respiratory failure from progressive paralysis. Serum-negative MG diagnosed, given the response to IVIG and pyridostigmine. The patient, amid acute crisis, refused therapies and wanted to transition to DNR-comfort care despite understanding the reversibility of her illness. Her family members supported comfort care option. Neurology was conflicted with the patient's choice because MG was treatable. Palliative care, ethics, and neuropsychology consulted to establish decision-making capacity, goals-of-care, and holistic support. Intervention(s): Palliative team utilized the CRISIS approach to address the impasse between the patient and the clinicians: 1. Continue care, collaborate with the teams 2. Respond empathetically 3. Integrate patient's autonomy 4. Support holistically 5. Improvise a care plan 6. Sustain quality of life We validated patient's autonomy. We recommended allowing time for the patient/family to process her illness. We continued holistic support and symptom management and created an improvised multidisciplinary plan to help her cope with the acute illness. The above approach enabled her to opt for therapies instead of comfort care only, and she gradually recovered. Respecting patients' autonomy and incorporating beneficence via our intervention led to positive outcomes. The CRISIS approach could help other clinicians in the situation when conflict arises between autonomy and beneficence.Copyright © 2023
ABSTRACT
During the Covid-19 pandemic attempts have been made to manage patients with neurological symptoms remotely without a neurological examination. To determine the prevalence of neurological signs we prospectively assessed 101 consecutive patients who were a referred to a general neurology clinic. Three patients did not attend, leaving 98 patients (58 female, 40 male, mean age 51.0 years, standard deviation 19.9 years. 37 patients had neurological signs. (Cognitive impairment n=3, spastic tetraparesis n=1, spastic hemipa- resis n=2, hemianopia n=1, ataxia n=1, gait apraxia n=1, postural tremor n=2, bradykinesia and rigidity n=9, functional tremor n=4, anosmia n=1, combined upper and lower motor neuron signs, n=2, radicular distribution numbness n=1, distal symmetrical weakness and hypoaesthesia n=5, peripheral nerve hypo- aesthesia n=2, fatigability and lid lag n=2.) Our data showed that a large proportion of general neurology patients had neurological signs.
ABSTRACT
Background: Many central and peripheral nervous system complications, following COVID-19 vaccination, have been described. We report an unusual case of central demyelinating disorder, following the administration of the ChAdOx1 nCoV-19 SARS-CoV-2 (COVISHIELDTM) vaccine. Case-report: The 28-year female developed sudden onset headache followed by weakness of the left upper and lower limbs, and gait ataxia. Neurological symptoms developed two weeks after administration of the first dose of the ChAdOx1 nCoV-19 SARS-CoV-2 (COVISHIELDTM) vaccine. Magnetic resonance imaging brain revealed T2/FLAIR hyperintense lesions involving bilateral subcortical white matter, splenium of the corpus callosum, and both cerebellar hemispheres. Few lesions showed blooming on gradient echo sequence suggestive of a hemorrhagic component. Post-contrast T1 images showed mild enhancement of demyelinating lesions. The patient was treated intravenously with methylprednisolone. After 12 weeks of follow-up, there was a substantial improvement in her symptoms. She became independent in all her activities of daily living. Conclusion(s): In conclusion, this is an unusual case of acute hemorrhagic leukoencephalitis following ChAdOx1 nCoV-19 SARS-CoV-2 (COVISHIELDTM) vaccination.Copyright © 2022 The Author(s)

ABSTRACT
Background: Although rarely, vaccines can stimulate the immunological mechanisms underlying immune-mediated inflammatory diseases. in patients with COVID-19 there is also evidence that high titers of autoantibodies, with variable clinical relevance, can be detected. Method(s): We describe the case of a 71-year- old lady diagnosed with eosinophilic granulomatosis with polyangiitis (EGPA) in 2010 with paraesthesia, myalgia, eosinophilia and severe asthma. After induction of remission, the patient has shown regression of the vasculitis but persistence of the uncontrolled asthma. For this reason, since February 2019 she started Mepolizumab 100 mg/month. In December 2020 she tested positive for the SARS-CoV- 2 virus, manifesting a mild form then she tested negative in January 2021. In April 2021 she was vaccinated with a single dose of BNT162b2 mRNA vaccine. After about 10 days, she started to complain arthromyalgia and after a week of gait alteration, paraesthesia, dyspnoea and worsening cough associated with chest pain. Blood tests showed an increase in creatinephosphokinase (CPK 955 U/L) and hypereosinophilia (4.3x10
ABSTRACT
Intelligent multi-purpose robotic assistants have the potential to assist nurses with a variety of non-critical tasks, such as object fetching, disinfecting areas, or supporting patient care. This paper focuses on enabling a multi-purpose robot to guide patients while walking. The proposed robotic framework aims at enabling a robot to learn how to navigate a crowded hospital environment while maintaining contact with the patient. Two deep reinforcement learning models are developed;the first model considers only dynamic obstacles (e.g., humans), while the second model considers static and dynamic obstacles in the environment. The models output the robot's velocity based on the following inputs;the patient's gait velocity, which is computed based on a leg detection method, spatial and temporal information from the environment, the humans in the scene, and the robot. The proposed models demonstrate promising results. Finally, the model that considers both static and dynamic obstacles is successfully deployed in the Gazebo simulation environment.
ABSTRACT
In the present scenario like COVID-19 pandemic, to maintain physical distance, the gait-based biometric is a must. Human gait identification is a very difficult process, but it is a suitable distance biometric that also gives good results at low resolution conditions even with face features that are not clear. This study describes the construction of a smart carpet that measures ground response force (GRF) and spatio-temporal gait parameters (STGP) using a polymer optical fiber sensor (POFS). The suggested carpet contains two light detection units for acquiring signals. Each unit obtains response from 10 nearby sensors. There are 20 intensity deviation sensors on a fiber. Light-emitting diodes (LED) are triggered successively, using the multiplexing approach that is being employed. Multiplexing is dependent on coupling among the LED and POFS sections. Results of walking experiments performed on the smart carpet suggested that certain parameters, including step length, stride length, cadence, and stance time, might be used to estimate the GRF and STGP. The results enable the detection of gait, including the swing phase, stance, stance length, and double supporting periods. The suggested carpet is dependable, reasonably priced equipment for gait acquisition in a variety of applications. Using the sensor data, gait recognition is performed using genetic algorithm (GA) and particle swarm optimization (PSO) technique. GA- and PSO-based gait template analyses are performed to extract the features with respect to the gait signals obtained from polymer optical gait sensors (POGS). The techniques used for classification of the obtained signals are random forest (RF) and support vector machine (SVM). The accuracy, sensitivity, and specificity results are obtained using SVM classifier and RF classifier. The results obtained using both classifiers are compared. © 2023 Mamidipaka Hema et al.
ABSTRACT
Introduction: EMGT is an effective, evidence based intervention for improving mobility outcomes in people with stroke. It enables highly repetitive stepping practice, in patients who are unable to stand/step. Despite being recommended in national guidance, adoption within the UK is extremely limited. We report preliminary data from its implementation in an NHS stroke service. Method(s): We initiated use of EMGT in our Acute Stroke Unit in November 2021 - implementation has been phased, and use was limited at times due to the COVID-19 pandemic. Patient demographics, clinical outcome measures and discharge information are recorded pre- and post-treatment. Result(s): To date, 38 patients have used EMGT, accumulating 232 sessions of walking. 74% of patients were male. . Mean age was 73.5 years (range 51 - 91). 19 patients used EMGT for >=3 sessions;of those, 14 completed > 6 sessions. Median Functional Ambulatory Category (FAC) at baseline was 0 (range 0-1), rising post treatment to 2 (range 0-4). Mean modified Rivermead Mobility Index rose from 13.5 to 24.3. 57% of patients who used EMGT as part of their rehabilitation programme were able to mobilise at least 10 metres post intervention. Initially, only 1 patient could manage a step transfer and following treatment this increased to 8. Conclusion(s): Early results indicate that EMGT is feasible in an acute NHS setting, alongside conventional care. It enables early and highly intensive mobilisation, resulting in improved function. Further work is required to develop clinical protocols, establishing recommended dose, time after stroke for EMGT initiation, and recommended duration of treatment.
ABSTRACT
A fall in third age triggers a domino effect of consequences that are recognized by specialists as leading causes of further falls. After the first event, the post-fall syndrome onsets: a pathological fear of falling that affects quality of life. It leads to loss of self-efficacy, sedentarism, musculoskeletal weakening, reduced mobility, postural insufficiency, gait disorders, isolation and depression—all acknowledged as fall risk factors. Specialists agreed that the most effective approach to prevent new episodes is to restore confident postures and good alignments. This paper presents the first design stages of a soft-actuated re-educational garment for remote post-fall rehabilitation in female users. The objective is to i) restore postural control by providing a gentle pressure stimulus, suggesting corrections when poor body alignments are detected;ii) restore the perceived self-efficacy;iii) promote physical activity by motion monitoring and providing daily reports through a patient-therapist smartphone app. To date, we have tested a soft body-postures detection system by cross-checking data from a network of e-textile stretch sensors, along with a pneumatic actuator system around the user's torso providing a targeted pressure stimulus to correct bad habits. Tests have been run on a limited number of users due to the Covid-19 emergency. Data are not yet statistically conclusive but suggest the way to a new dimensional approach, both for rehabilitation and prevention. © 2023, ICST Institute for Computer Sciences, Social Informatics and Telecommunications Engineering.

Background: The large proportion of coronavirus disease 2019 (COVID-19) patients has been associated with a large number of neu-ropsychiatric manifestations. Despite the high prevalence of COVID-19, few studies have examined such manifestations, especially in children and adolescents. Objective(s): This study investigated neuropsychiatric manifestations in hospitalized children and adolescents admitted for COVID-19 infection in Iran. Method(s): This prospective observational study included admitted children and adolescents (4-18 years old) diagnosed with COVID-19 infection, pediatric neurologists, child and adolescent psychiatrists, and infectious disease specialists, and assessed 375 infected patients during August and December 2021. Result(s): Of the 375 patients, 176 (47%) were female, with a mean age of 9.0 +/- 3.39 years. Psychiatric and neurological manifestations were reported in 58 (15.5%) and 58 (15.5%) patients, respectively. The most prevalent psychiatric disorders were separation anxiety disorder (SAD) (5.1%), major depressive disorder (MDD) (3.5%), generalized anxiety disorder (GAD) (2.7%), insomnia (2.4%), and op-positional defiant disorder (ODD) (2.4%). Regarding neurological complications, seizures were the most prevalent (13.1%), followed by encephalitis (1.9%), transverse myelitis (0.3%), acute ischemic stroke (0.3%), and Guillain-Barre syndrome (0.3%). There was no significant relationship between the duration of COVID-19 infection (P = 0.54) and ICU admission (P = 0.44) with the emergence of psychiatric symptoms. Conclusion(s): The most prevalent neurologic and psychiatric complications among children and adolescents with COVID-19 infection were seizures and the symptoms of anxiety/mood disorders, respectively.Copyright © 2023, Author(s).
