Introduction<\/strong><\/p>\n\n\n\n The emergence of SARS-CoV-2 in late 2019 marked the beginning of a global health crisis that has since reshaped the landscape of medicine, public health, and scientific inquiry. Initially characterized as a respiratory pathogen, the virus has demonstrated a remarkable capacity for multisystem involvement, with neurological complications increasingly recognized as central to both acute and post-acute manifestations. Among these, the involvement of the peripheral nervous system (PNS)\u2014and specifically motor nerves\u2014has garnered attention for its potential to cause profound functional impairment, disability, and long-term sequelae.<\/p>\n\n\n\n Motor nerves, responsible for transmitting signals from the central nervous system to skeletal muscles, are essential for voluntary movement, coordination, and reflex integrity. Damage to these nerves can result in weakness, paralysis, and loss of motor control, with cascading effects on mobility, independence, and quality of life. While sensory neuropathies have been more commonly reported in the context of COVID-19, emerging evidence suggests that motor nerve involvement, though less frequent, may be underrecognized and clinically significant.<\/p>\n\n\n\n In a systematic review published in PLOS ONE<\/em>, Hanganu et al. analyzed 225 studies encompassing 1,004 patients with COVID-19 and peripheral nervous system involvement. Of these, 350 cases (26.5%) were classified as PNS events, with motor neuropathies\u2014particularly those within the Guillain-Barr\u00e9 syndrome (GBS) spectrum\u2014accounting for a substantial proportion. Acute motor axonal neuropathy (AMAN), acute motor sensory axonal neuropathy (AMSAN), and pharyngeal-cervical-brachial variants were among the subtypes identified, underscoring the diversity of motor presentations associated with SARS-CoV-2 infection.\u00b9<\/p>\n\n\n\n The pathogenesis of motor nerve involvement in COVID-19 is multifactorial. Direct viral neurotropism, immune-mediated demyelination, vascular injury, and systemic inflammation have all been implicated. The virus\u2019s affinity for angiotensin-converting enzyme 2 (ACE2) receptors, expressed in neuronal and glial tissues, provides a plausible mechanism for central and peripheral nervous system entry.\u00b2 Moreover, the cytokine storm characteristic of severe COVID-19 may precipitate autoimmune responses targeting myelin and axonal structures, akin to post-infectious neuropathies observed in other viral illnesses.<\/p>\n\n\n\n Clinically, motor neuropathies in COVID-19 may present acutely or insidiously. Patients may report limb weakness, facial paresis, dysphagia, or respiratory compromise due to diaphragmatic involvement. Electrophysiological studies often reveal reduced compound muscle action potentials (CMAPs), prolonged distal latencies, and conduction blocks, consistent with demyelinating or axonal pathology.\u00b3 In some cases, motor symptoms emerge during the recovery phase, suggesting a delayed immune response rather than direct viral cytotoxicity.<\/p>\n\n\n\n Treatment strategies for COVID-19-associated motor neuropathies mirror those for idiopathic GBS and related conditions. Intravenous immunoglobulin (IVIG) and plasma exchange remain the mainstays of therapy, with corticosteroids playing a more limited role. Early intervention is critical, as delayed treatment may result in irreversible axonal loss and prolonged rehabilitation.\u2074 Prognosis varies depending on the subtype, severity, and timing of intervention, with some patients achieving full recovery and others experiencing persistent deficits.<\/p>\n\n\n\n Beyond the acute phase, motor nerve involvement may contribute to the constellation of symptoms known as Long COVID or post-acute sequelae of SARS-CoV-2 infection (PASC). Fatigue, exercise intolerance, and neuromuscular weakness are frequently reported, raising questions about subclinical motor neuropathy and mitochondrial dysfunction.\u2075 Longitudinal studies are needed to elucidate the natural history of motor involvement and to develop targeted rehabilitation protocols.<\/p>\n\n\n\n The implications of motor nerve involvement in COVID-19 extend beyond individual morbidity. At a population level, they contribute to increased healthcare utilization, disability claims, and socioeconomic burden. Recognition of these complications is essential for early diagnosis, appropriate referral, and multidisciplinary management. Neurologists, physiatrists, and rehabilitation specialists must collaborate to optimize outcomes and support recovery.<\/p>\n\n\n\n In conclusion, while motor nerve involvement in COVID-19 may be less prevalent than sensory or autonomic manifestations, its impact on function and quality of life is profound. Continued research into its pathophysiology, clinical spectrum, and therapeutic approaches is warranted. As our understanding of SARS-CoV-2 evolves, so too must our appreciation for its neurological footprint\u2014a footprint that includes the silent erosion of motor integrity in the wake of viral assault.<\/p>\n\n\n\n The clinical spectrum of motor nerve involvement in COVID-19 is broad, ranging from subtle weakness and fatigue to fulminant paralysis. While sensory neuropathies and autonomic dysfunction have dominated early reports, motor presentations\u2014particularly those resembling Guillain-Barr\u00e9 syndrome (GBS) and its variants\u2014are increasingly recognized as part of the post-viral neurological landscape. These manifestations may occur during acute infection, in the subacute recovery phase, or as part of the chronic symptomatology of Long COVID.<\/p>\n\n\n\n In the acute setting, motor nerve involvement often presents as a rapidly progressive weakness, typically ascending in nature, and may be accompanied by areflexia and mild sensory changes. This classic presentation mirrors that of GBS, a post-infectious autoimmune polyradiculoneuropathy. In a multicenter study conducted in Italy during the early months of the pandemic, Toscano et al. described five patients who developed GBS within 5 to 10 days of COVID-19 symptom onset. Electrophysiological studies revealed demyelinating features in three patients and axonal damage in two, consistent with acute motor axonal neuropathy (AMAN) and acute motor sensory axonal neuropathy (AMSAN) subtypes.\u00b9<\/p>\n\n\n\n Facial diplegia, bulbar weakness, and respiratory compromise have also been reported, particularly in patients with pharyngeal-cervical-brachial variants.\u00b2 These presentations underscore the need for vigilance in patients with new-onset weakness, especially when accompanied by cranial nerve involvement or declining respiratory function. Early recognition and initiation of intravenous immunoglobulin (IVIG) or plasma exchange are critical to prevent irreversible axonal loss.<\/p>\n\n\n\n Beyond the acute phase, motor symptoms may emerge insidiously, often in the context of Long COVID. Patients report persistent limb weakness, exercise intolerance, and difficulty performing fine motor tasks. These symptoms may be misattributed to deconditioning or fatigue, yet electrophysiological studies frequently reveal reduced compound muscle action potentials (CMAPs), prolonged distal latencies, and decreased motor conduction velocities.\u00b3<\/p>\n\n\n\n In a cohort study from Massachusetts General Hospital, Oaklander et al. evaluated 17 patients with persistent neurological symptoms following mild COVID-19. Nerve conduction studies revealed evidence of small-fiber neuropathy in 59% of patients, with mixed sensory-motor involvement in several cases.\u2074 Muscle biopsies demonstrated mitochondrial abnormalities and fiber-type grouping, suggestive of chronic denervation and reinnervation.<\/p>\n\n\n\n Focal motor neuropathies have also been documented, including mononeuritis multiplex and isolated cranial nerve palsies. Cases of unilateral facial paralysis, abducens nerve palsy, and vocal cord paresis have been reported, often without accompanying sensory deficits.\u2075 These presentations may reflect localized immune-mediated inflammation or microvascular ischemia affecting motor fibers.<\/p>\n\n\n\n In one illustrative case, a 42-year-old man developed isolated right peroneal nerve palsy two weeks after recovering from mild COVID-19. Electromyography confirmed denervation in the tibialis anterior and extensor digitorum longus muscles, with no sensory involvement. MRI of the lumbosacral plexus was unremarkable, and serological testing ruled out other autoimmune etiologies. The patient responded to a short course of corticosteroids and physical therapy, with partial recovery at three months.\u2076<\/p>\n\n\n\n Motor nerve involvement may extend to the diaphragm and intercostal muscles, contributing to dyspnea and reduced ventilatory capacity. This is particularly relevant in patients with pre-existing neuromuscular disorders or those recovering from prolonged mechanical ventilation. Diaphragmatic weakness may be subtle and underdiagnosed, yet it has significant implications for rehabilitation and functional recovery.<\/p>\n\n\n\n Ultrasound and fluoroscopic sniff tests can aid in the diagnosis of diaphragmatic dysfunction, while electromyography of the phrenic nerve provides definitive evidence.\u2077 Management includes respiratory physiotherapy, non-invasive ventilation support, and close monitoring of oxygenation and carbon dioxide retention.<\/p>\n\n\n\n In the context of Long COVID, motor fatigue is a prominent and disabling symptom. Patients describe a sense of heaviness in the limbs, reduced endurance, and delayed recovery after exertion. This phenotype overlaps with myalgic encephalomyelitis\/chronic fatigue syndrome (ME\/CFS), and may reflect central and peripheral motor dysfunction.<\/p>\n\n\n\n Functional MRI studies have demonstrated altered activation patterns in motor cortices of Long COVID patients, while transcranial magnetic stimulation reveals reduced motor evoked potentials.\u2078 These findings suggest impaired cortical excitability and disrupted motor planning, possibly secondary to neuroinflammation and neurotransmitter imbalance.<\/p>\n\n\n\n The pathophysiology of motor nerve involvement in COVID-19 is complex, multifactorial, and still evolving. Evidence suggests that SARS-CoV-2 does not typically exert direct cytopathic effects on motor neurons; rather, its impact is mediated through immune dysregulation, vascular injury, and systemic inflammation. These mechanisms converge to produce a spectrum of neuropathic presentations, ranging from acute demyelination to chronic axonal degeneration.<\/p>\n\n\n\n The most widely recognized mechanism is immune-mediated demyelination, exemplified by Guillain-Barr\u00e9 syndrome (GBS). Molecular mimicry between viral antigens and peripheral nerve components triggers an autoimmune response, leading to complement activation and macrophage-mediated stripping of myelin.\u00b9 The result is conduction block, slowed nerve transmission, and motor weakness. Acute motor axonal neuropathy (AMAN) and acute motor sensory axonal neuropathy (AMSAN) represent variants in which axonal injury predominates, often associated with poorer prognosis.\u00b2<\/p>\n\n\n\n Severe COVID-19 is characterized by a cytokine storm, with elevated levels of interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-\u03b1), and interleukin-1\u03b2.\u00b3 These pro-inflammatory mediators cross the blood-brain barrier and disrupt neuronal homeostasis. In peripheral nerves, they induce Schwann cell dysfunction, impair remyelination, and promote axonal degeneration. Neuroinflammation also alters synaptic transmission in motor pathways, contributing to fatigue and impaired coordination.<\/p>\n\n\n\n SARS-CoV-2 induces endothelial dysfunction and a prothrombotic state, leading to microvascular injury in both central and peripheral nervous systems.\u2074 Motor nerves, dependent on vasa nervorum for perfusion, are vulnerable to ischemic injury. Microthrombosis impairs nutrient delivery, resulting in axonal degeneration and focal motor deficits. This mechanism may explain cases of mononeuritis multiplex and isolated cranial nerve palsies observed in COVID-19 patients.\u2075<\/p>\n\n\n\n Although less common, direct viral invasion of neural tissue has been documented. SARS-CoV-2 binds to angiotensin-converting enzyme 2 (ACE2) receptors expressed on neurons and glial cells.\u2076 Autopsy studies have identified viral RNA and proteins in cranial nerves and brainstem nuclei, suggesting a potential route of entry via the olfactory mucosa.\u2077 While evidence for direct infection of motor neurons remains limited, the possibility of localized viral persistence cannot be excluded.<\/p>\n\n\n\n Emerging data implicate mitochondrial dysfunction in the neuromuscular manifestations of Long COVID. Muscle biopsies from affected patients reveal abnormal mitochondrial morphology, reduced oxidative phosphorylation, and impaired ATP production.\u2078 These changes compromise motor neuron energy metabolism, leading to central fatigue and impaired neuromuscular transmission. The overlap with myalgic encephalomyelitis\/chronic fatigue syndrome (ME\/CFS) suggests a shared pathophysiological substrate.<\/p>\n\n\n\n The glymphatic system, responsible for clearing metabolic waste from the central nervous system during sleep, may be impaired in COVID-19.\u2079 Microvascular injury and astrocytic dysfunction reduce cerebrospinal fluid flow, leading to accumulation of neurotoxic metabolites. While primarily implicated in cognitive dysfunction, glymphatic impairment may also affect motor pathways by disrupting neuronal homeostasis and synaptic plasticity.<\/p>\n\n\n\n The consequences of motor nerve involvement in COVID-19 extend far beyond the immediate neurological deficits. They encompass functional impairment, long-term disability, psychosocial burden, and socioeconomic impact. As the pandemic evolves, these sequelae are increasingly recognized as critical determinants of patient outcomes and healthcare system strain.<\/p>\n\n\n\n Motor neuropathies manifest as weakness, paralysis, and loss of coordination, directly undermining mobility and independence. Patients with Guillain-Barr\u00e9 syndrome (GBS) or acute motor axonal neuropathy (AMAN) may require mechanical ventilation due to diaphragmatic paralysis, while others struggle with basic activities of daily living such as walking, dressing, or feeding.\u00b9 Even mild motor deficits can significantly reduce endurance and dexterity, impairing occupational performance and quality of life. Rehabilitation is often prolonged, requiring months of physiotherapy and occupational therapy, with variable recovery trajectories.\u00b2<\/p>\n\n\n\n Motor dysfunction rarely occurs in isolation. Fatigue, sleep disturbances, and cognitive impairment frequently accompany neuromuscular weakness, compounding disability.\u00b3 Patients report frustration, anxiety, and depression stemming from loss of autonomy and uncertainty about recovery. The overlap with post-viral syndromes such as myalgic encephalomyelitis\/chronic fatigue syndrome (ME\/CFS) highlights the bidirectional relationship between motor impairment and neuropsychiatric sequelae.\u2074<\/p>\n\n\n\n Reduced mobility contributes to secondary complications including venous thromboembolism, insulin resistance, and sarcopenia.\u2075 Prolonged immobility exacerbates cardiovascular risk, while muscle atrophy impairs metabolic regulation. These systemic consequences further increase healthcare utilization and complicate recovery, particularly in older adults and those with comorbidities.<\/p>\n\n\n\n Rehabilitation of COVID-19 patients with motor neuropathies presents unique challenges. Traditional protocols for GBS and peripheral neuropathy must be adapted to account for ongoing inflammation, autonomic dysfunction, and fluctuating fatigue.\u2076 Multidisciplinary teams\u2014including neurologists, physiatrists, respiratory therapists, and psychologists\u2014are essential to address the complex interplay of motor, cognitive, and emotional deficits. Access to rehabilitation services remains uneven, with disparities exacerbated by socioeconomic factors and healthcare system strain.<\/p>\n\n\n\n At a population level, motor nerve involvement contributes to increased disability claims, loss of workforce productivity, and long-term care needs.\u2077 Patients with persistent motor deficits may be unable to return to employment, leading to financial hardship and social isolation. The cumulative burden on healthcare systems includes extended hospital stays, rehabilitation costs, and long-term support services. Recognition of these consequences is vital for resource allocation and policy planning.<\/p>\n\n\n\n Longitudinal studies suggest that recovery from COVID-19-associated motor neuropathies is variable. Some patients achieve near-complete recovery within months, while others experience persistent weakness, fatigue, or relapses.\u2078 Prognosis depends on the subtype of neuropathy, severity of initial presentation, and timing of intervention. Persistent deficits highlight the need for ongoing monitoring, rehabilitation, and research into neuroprotective therapies.<\/p>\n\n\n\n The management of motor neuropathies associated with COVID-19 requires a nuanced approach that integrates acute interventions, long-term rehabilitation, and supportive care. While many therapeutic strategies are extrapolated from established protocols for Guillain-Barr\u00e9 syndrome (GBS) and peripheral neuropathies, the unique pathophysiological features of SARS-CoV-2 infection demand tailored considerations.<\/p>\n\n\n\n Intravenous Immunoglobulin (IVIG)<\/strong> IVIG remains the cornerstone of therapy for immune-mediated motor neuropathies such as GBS. Its immunomodulatory effects include neutralization of pathogenic antibodies, inhibition of complement activation, and suppression of pro-inflammatory cytokines.\u00b9 Early administration within two weeks of symptom onset is associated with improved outcomes, reducing the risk of irreversible axonal damage.<\/p>\n\n\n\n Plasma Exchange (Plasmapheresis)<\/strong> Plasma exchange is equally effective in acute GBS and may be preferred in patients with contraindications to IVIG.\u00b2 By removing circulating autoantibodies and immune complexes, plasmapheresis halts ongoing demyelination and facilitates recovery. Timing is critical; delayed initiation diminishes efficacy.<\/p>\n\n\n\n Corticosteroids<\/strong> The role of corticosteroids in COVID-19-associated motor neuropathies is limited. While beneficial in systemic inflammation and respiratory compromise, corticosteroids have not demonstrated consistent efficacy in GBS.\u00b3 Their use may be considered in focal mononeuritis multiplex or vasculitic neuropathies, where inflammation predominates.<\/p>\n\n\n\n Respiratory Support<\/strong> Motor neuropathies involving the diaphragm and intercostal muscles necessitate vigilant respiratory monitoring. Non-invasive ventilation or intubation may be required in severe cases.\u2074 Early recognition of respiratory muscle weakness is essential to prevent hypoxemia and hypercapnia.<\/p>\n\n\n\n Pain Management<\/strong> Neuropathic pain, though less prominent in motor neuropathies, may coexist with sensory involvement. Agents such as gabapentin, pregabalin, and duloxetine can provide relief, improving patient comfort and facilitating rehabilitation.\u2075<\/p>\n\n\n\n Physiotherapy and Occupational Therapy<\/strong> Rehabilitation is central to recovery, addressing muscle weakness, coordination deficits, and functional limitations. Tailored physiotherapy programs emphasize strength training, endurance building, and gait retraining. Occupational therapy focuses on restoring independence in daily activities, employing adaptive devices where necessary.\u2076<\/p>\n\n\n\n Respiratory Physiotherapy<\/strong> For patients with diaphragmatic involvement, respiratory physiotherapy enhances ventilatory capacity and reduces the risk of complications. Techniques include incentive spirometry, diaphragmatic breathing, and assisted coughing.\u2077<\/p>\n\n\n\n Multidisciplinary Approach<\/strong> Optimal rehabilitation requires collaboration among neurologists, physiatrists, respiratory therapists, psychologists, and social workers. This holistic model addresses not only motor deficits but also cognitive, emotional, and social dimensions of recovery.<\/p>\n\n\n\n Immunotherapies<\/strong> Emerging evidence suggests that low-dose naltrexone and other immunomodulatory agents may benefit patients with persistent motor fatigue and immune dysregulation in Long COVID.\u2078 These therapies remain experimental but highlight the need for innovation in chronic management.<\/p>\n\n\n\n Neuroprotective Agents<\/strong> Research into neuroprotective compounds, including antioxidants and mitochondrial stabilizers, is ongoing. Their potential to mitigate axonal degeneration and enhance recovery warrants further investigation.<\/p>\n\n\n\n Lifestyle and Self-Management<\/strong> Patients are encouraged to adopt structured routines emphasizing sleep hygiene, balanced nutrition, and graded exercise. These measures support neuromuscular recovery and reduce the risk of relapse.<\/p>\n\n\n\n The NIH RECOVER initiative and other international consortia are actively investigating therapeutic strategies for Long COVID, including motor neuropathies. Trials evaluating IVIG, plasma exchange, and novel immunotherapies will provide critical insights into efficacy and safety.\u2079 Longitudinal studies are essential to define prognosis, identify biomarkers of recovery, and guide personalized treatment.<\/p>\n\n\n\n The recognition of motor nerve involvement in COVID-19 expands our understanding of the virus\u2019s neurological footprint and underscores the need for a multidisciplinary approach to patient care. While sensory neuropathies and cognitive sequelae have dominated early discourse, motor dysfunction\u2014though less prevalent\u2014carries profound implications for functional independence, rehabilitation, and long-term outcomes.<\/p>\n\n\n\n The convergence of clinical observations and mechanistic studies paints a picture of multifactorial injury. Immune-mediated demyelination, vascular compromise, mitochondrial dysfunction, and possible direct viral neurotropism all contribute to motor deficits.\u00b9 The heterogeneity of presentations\u2014from acute Guillain-Barr\u00e9 syndrome to insidious motor fatigue in Long COVID\u2014suggests that SARS-CoV-2 acts as both a trigger and a perpetuator of neuromuscular pathology. This complexity challenges clinicians to move beyond reductionist models and embrace integrative frameworks that account for systemic, neurological, and psychosocial dimensions.<\/p>\n\n\n\n Despite growing evidence, significant gaps remain. Epidemiological data on motor neuropathies in COVID-19 are limited by small sample sizes, referral bias, and reliance on case reports.\u00b2 Objective measures such as electromyography, nerve conduction studies, and muscle biopsies are underutilized, leaving many cases uncharacterized. The natural history of motor involvement\u2014its onset, progression, and resolution\u2014remains poorly defined. Furthermore, the long-term impact on functional capacity, employment, and quality of life has yet to be systematically studied.<\/p>\n\n\n\n Treatment strategies for COVID-19-associated motor neuropathies largely mirror those for idiopathic GBS and peripheral neuropathies. While IVIG and plasma exchange are effective in acute immune-mediated cases, their role in subacute or chronic motor fatigue is unclear.\u00b3 Emerging therapies such as low-dose naltrexone, mitochondrial stabilizers, and neuroprotective agents hold promise but lack robust clinical trial data. Rehabilitation protocols must be adapted to account for fluctuating fatigue, autonomic dysfunction, and cognitive impairment, yet standardized guidelines are absent.<\/p>\n\n\n\n Motor dysfunction in Long COVID raises pressing questions about pathogenesis and management. Is persistent weakness a manifestation of ongoing immune activation, irreversible axonal loss, or central nervous system dysregulation?\u2074 The overlap with ME\/CFS suggests shared mechanisms, including mitochondrial impairment and neuroinflammation. Addressing motor fatigue requires not only symptomatic treatment but also mechanistic research to identify biomarkers and therapeutic targets.<\/p>\n\n\n\n At a societal level, motor nerve involvement contributes to disability, healthcare utilization, and economic burden. Patients with persistent deficits may be unable to return to work, leading to financial hardship and increased reliance on social support systems.\u2075 Policymakers must recognize these consequences in resource allocation, disability assessment, and rehabilitation funding. The integration of neurology, rehabilitation medicine, and public health is essential to mitigate the long-term impact.<\/p>\n\n\n\n Future research should prioritize:<\/p>\n\n\n\n Footnotes<\/strong><\/p>\n\n\n\n John Murphy, CEO The COVID-19 Long-haul Foundation Introduction The emergence of SARS-CoV-2 in late 2019 marked the beginning of a global health crisis that has since reshaped the landscape of […]<\/p>\n","protected":false},"author":2,"featured_media":14451,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[58,334,362],"tags":[],"class_list":["post-14006","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-brain","category-motor-nerves","category-neurodegeneration"],"_links":{"self":[{"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=\/wp\/v2\/posts\/14006","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=14006"}],"version-history":[{"count":8,"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=\/wp\/v2\/posts\/14006\/revisions"}],"predecessor-version":[{"id":14014,"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=\/wp\/v2\/posts\/14006\/revisions\/14014"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=\/wp\/v2\/media\/14451"}],"wp:attachment":[{"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=14006"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=14006"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/cov19longhaulfoundation.org\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=14006"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}Clinical Manifestations of Motor Nerve Involvement in COVID-19<\/h2>\n\n\n\n
