Medullary (Caudal) Ipsilateral Hemiplegia, often referred to as Opalski syndrome, is a rare form of brainstem stroke in which the infarct involves the lateral aspect of the lower (caudal) medulla oblongata and extends ventrally to damage the corticospinal fibers after they have crossed (decussated) in the pyramidal decussation. This produces a paradoxical weakness or paralysis of the same side (ipsilateral) of the body as the lesion, rather than the more typical contralateral presentation seen in most upper motor neuron lesions jamanetwork.compubmed.ncbi.nlm.nih.gov.
Medullary (caudal) ipsilateral hemiplegia is a rare and often under-recognized neurological syndrome characterized by paralysis on one side of the body resulting from lesions in the lower (caudal) portion of the medulla oblongata. This condition typically arises from vascular insults—most commonly lateral medullary (Wallenberg) infarcts or hemorrhages—affecting the corticospinal tract as it descends through the medulla. Patients present with motor weakness, spasticity, and sensory changes on the same side as the lesion, alongside cranial nerve deficits. Early recognition and a multidisciplinary approach to treatment can greatly improve functional outcomes and quality of life.
Pathophysiology
Medullary ipsilateral hemiplegia occurs when a lesion in the caudal medulla disrupts the corticospinal fibers before they decussate at the pyramidal decussation. Because the fibers cross at this level, damage just above the decussation produces weakness or paralysis on the same side as the lesion. Lesions may arise from ischemic stroke (often vertebral artery or posterior inferior cerebellar artery infarcts), hemorrhage, demyelination, or neoplasm. The hallmark signs include ipsilateral limb weakness or paralysis, increased muscle tone (spasticity), hyperreflexia, and sometimes Babinski sign, combined with cranial nerve nuclei involvement leading to dysphagia, dysarthria, and palate droop. Understanding the precise vascular territories and neuronal pathways helps clinicians pinpoint the lesion and tailor interventions.
Clinically, patients present with the classic features of lateral medullary (Wallenberg) syndrome—such as dysphagia, hoarseness, vertigo, ataxia, and sensory disturbances—plus a spastic hemiparesis of the limbs on the same side as the infarct. Pathologically, this occurs because the lesion encroaches upon the pyramidal tract fibers after their decussation at the cervicomedullary junction, interrupting upper motor neuron signals destined for the ipsilateral spinal cord pubmed.ncbi.nlm.nih.gov.
Types
While Opalski syndrome is the prototypical cause of medullary ipsilateral hemiplegia, related variants include:
Opalski Syndrome
An infarction of the PICA or vertebral artery that extends into the ventral caudal medulla, damaging post-decussating corticospinal fibers and producing ipsilateral hemiplegia alongside lateral medullary signs jamanetwork.com.Hemimedullary Syndrome (Reinhold’s Syndrome)
A rare combination of medial and lateral medullary infarcts, this “hemimedullary” lesion affects both the medial lemniscus and pyramidal tract before and after decussation, often including hypoglossal nerve involvement and ipsilateral weakness pubmed.ncbi.nlm.nih.gov.Arterial Dissection Variant
Vertebral artery dissection may selectively compromise branches supplying the caudal medulla and the pyramidal decussation, leading to ipsilateral weakness and cranial nerve deficits; case series report dissection in up to 29% of lateral medullary infarcts sciencedirect.comahajournals.org.Atypical PICA Infarct
Occasionally, PICA occlusion spares most cerebellar structures but extends into the ventrolateral medulla, producing ipsilateral motor deficits without full-blown lateral medullary syndrome features.
Causes
(Each cause listed with a brief, plain-English explanation.)
Large-artery Atherosclerosis
Build-up of plaque in the vertebral or PICA arteries can narrow or block blood flow to the caudal medulla. This is the most common mechanism in lateral medullary infarctions, accounting for roughly half of cases ncbi.nlm.nih.govthejcn.com.Arterial Dissection
A tear in the inner lining of the vertebral artery can create a false channel that reduces blood flow to medullary branches; up to 15–30% of cases involve dissection ncbi.nlm.nih.govahajournals.org.Small-vessel Lipohyalinosis
Chronic hypertension can damage small penetrating arteries supplying the medulla, leading to “lacunar” infarcts that occasionally involve the pyramidal decussation.Cardioembolism
Emboli from the heart (e.g., due to atrial fibrillation or endocarditis) can lodge in vertebral or PICA branches, though this accounts for fewer than 5% of medullary strokes pmc.ncbi.nlm.nih.gov.Hypercoagulable States
Conditions like antiphospholipid syndrome or protein C deficiency increase blood clotting, raising stroke risk even in relatively young patients.Vasculitis
Inflammatory diseases (e.g., lupus, giant cell arteritis) can narrow medullary vessels or cause thrombosis, leading to focal infarcts.Fibromuscular Dysplasia
A non-atherosclerotic, non-inflammatory arterial disease that can cause stenosis or dissection of vertebral arteries, impairing medullary perfusion.Moyamoya Disease
Progressive stenosis of intracranial arteries can affect posterior circulation branches, occasionally leading to medullary infarcts.Polycythemia Vera
Excess red cell mass thickens blood, increasing the risk of in situ thrombosis in small medullary vessels.Sickle Cell Disease
Sickling of red blood cells in small vessels can obstruct flow in penetrating arteries of the medulla.Septic Emboli
Infective endocarditis can shower the posterior circulation with bacterial clots, causing localized infarcts.Head and Neck Trauma
Whiplash or cervical injury can precipitate vertebral artery dissection or spasm, compromising medullary perfusion.Radiation-induced Vasculopathy
Previous neck or skull base radiotherapy may damage arteries years later, leading to stenosis or thrombosis.Paradoxical Embolism
A clot passing through a patent foramen ovale can travel to vertebral vessels and lodge in medullary branches.Drug Abuse
Vasospasm induced by substances such as cocaine or methamphetamine can transiently reduce medullary blood flow.Migraine-related Infarction
Rarely, severe migraine vasospasm can cause focal ischemia in brainstem structures.Systemic Hypotension
Sudden drops in blood pressure (e.g., during surgery) can precipitate watershed-type infarcts at the cervicomedullary junction.Hyperviscosity Syndromes
Conditions like Waldenström macroglobulinemia can increase blood thickness, risking small-vessel occlusion.Neoplastic Compression
Tumors at the foramen magnum or lower clivus (e.g., meningioma) may compress medullary vessels or the region of the pyramidal decussation.Demyelinating Lesions
Rarely, multiple sclerosis plaques can form in the caudal medulla, disrupting corticospinal fibers without true infarction.
Symptoms
(Plain-English paragraphs describing each clinical feature.)
Ipsilateral Limb Weakness
Patients often notice sudden weakness or difficulty moving one arm and leg on the same side as their brainstem stroke. This reflects damage to pyramidal fibers after they have crossed, so motor signals to that side of the body are interrupted.Spasticity and Hyperreflexia
Over time, ipsilateral weakness typically evolves into a spastic pattern, with stiff, tight muscles and brisk reflexes in the affected arm and leg.Facial Weakness
When the lesion extends to involve adjacent corticobulbar fibers, one side of the face may droop, making it hard to smile or close the eyelid fully on that side.Dysphagia (Difficulty Swallowing)
Involvement of the nucleus ambiguus—which controls muscles of the soft palate and pharynx—causes choking or coughing when swallowing liquids and solids ncbi.nlm.nih.gov.Dysarthria (Slurred Speech)
Weakness of palate, tongue, and laryngeal muscles leads to slurred, nasal, or hoarse speech quality.Vertigo and Dizziness
Stroke involvement of vestibular nuclei can provoke spinning sensations or unsteadiness, often accompanied by nausea.Ataxia (Incoordination)
Damage to the inferior cerebellar peduncle produces a lack of muscle coordination, causing clumsy, unsteady limb movements on the side of the lesion ncbi.nlm.nih.gov.Nystagmus (Abnormal Eye Movements)
Involvement of the vestibular pathways can lead to involuntary, rhythmic oscillation of the eyes, often beating toward the side of the lesion.Horner’s Syndrome
If descending sympathetic fibers are affected, patients exhibit drooping eyelid (ptosis), small pupil (miosis), and diminished facial sweating on the ipsilateral side.Ipsilateral Facial Numbness
Lesion of the spinal trigeminal nucleus causes loss of pain and temperature sensation on the same side of the face.Contralateral Body Sensory Loss
Because the spinothalamic tract lies lateral in the medulla, most patients lose pain and temperature sensations on the opposite side of the body.Hiccups
Irritation of medullary centers controlling diaphragm innervation can provoke persistent, often distressing hiccups.Nausea and Vomiting
Brainstem nuclei for vomiting may be triggered by stroke activity, leading to nausea that can complicate rehabilitation.Headache
Some patients experience a sudden, severe headache at onset, reflecting arterial occlusion or dissection.Facial Pain
Paradoxically, damage to trigeminal fibers can cause stabbing or burning pain in the face ipsilateral to the lesion.Loss of Gag Reflex
Impaired function of glossopharyngeal and vagus nerves often abolishes the normal gag response on the affected side.Hoarseness
Vocal cord weakness from nucleus ambiguus involvement can cause a husky or breathy voice quality.Palatal Myoclonus
Rare rhythmic contractions of the soft palate may occur if the central tegmental tract is involved.Dysphonia (Voice Changes)
Beyond hoarseness, patients may have difficulty modulating pitch and volume due to laryngeal muscle weakness.Post-stroke Depression
Though not a direct brainstem sign, many patients experience mood changes, feeling sad or hopeless as they cope with sudden disability.

Non-Pharmacological Treatments
A holistic, evidence-based rehabilitation program forms the cornerstone of recovery in medullary ipsilateral hemiplegia. Non-pharmacological therapies aim to restore function, prevent complications, and empower patients through self-management.
Physiotherapy and Electrotherapy Therapies
- Proprioceptive Neuromuscular Facilitation (PNF): PNF uses diagonal movement patterns to stimulate proprioceptors, enhancing motor control and strength. By applying manual resistance along specific muscle groups, PNF facilitates neural re-education and functional movement patterns.
- Mirror Therapy: In mirror therapy, patients perform movements with the unaffected limb while watching its reflection, which creates the illusion of movement in the paralyzed side. This visual feedback promotes cortical reorganization and motor recovery.
- Functional Electrical Stimulation (FES): FES delivers low-level electrical currents to paralyzed muscles to evoke contractions during functional tasks, improving muscle strength, preventing atrophy, and reinforcing motor pathways.
- Transcutaneous Electrical Nerve Stimulation (TENS): TENS provides cutaneous electrical stimulation to modulate pain through gate-control mechanisms and may indirectly facilitate participation in active rehabilitation by reducing discomfort.
- Neuromuscular Electrical Stimulation (NMES): Similar to FES but focused on individual muscle groups, NMES strengthens denervated or weak muscles by eliciting contractions via surface electrodes, supporting improved tone and voluntary control.
- Thermal Therapy (Heat and Cold): Heat increases tissue extensibility and reduces spasticity, aiding in stretching and mobilization, while cold can temporarily decrease spastic tone and pain to facilitate exercise.
- Ultrasound Therapy: Therapeutic ultrasound uses high-frequency sound waves to enhance tissue healing, reduce inflammation, and improve blood flow, supporting muscle recovery and flexibility.
- Low-Level Laser Therapy (LLLT): LLLT delivers light energy to tissues, promoting cellular metabolism, reducing inflammation, and potentially accelerating nerve regeneration.
- Extracorporeal Shockwave Therapy (ESWT): ESWT applies acoustic pressure waves to affected muscles and tendons, reducing spasticity and improving range of motion by modulating neuromuscular excitability.
- Kinesio Taping: Elastic therapeutic tape applied to skin over muscles can improve proprioception, support weak muscles, and reduce edema, facilitating better posture and movement.
- Manual Therapy (Joint Mobilization): Hands-on techniques by a physiotherapist to mobilize joints and soft tissues reduce pain, increase joint range, and prepare patients for active exercises.
- Task-Oriented Training: Repetitive practice of functional tasks (e.g., reaching, grasping, walking) enhances motor learning through brain plasticity, gradually improving independence in daily activities.
- Aquatic Therapy: Water-based exercise reduces gravitational load, allowing safer practice of movements, building strength, balance, and cardiovascular fitness in a supportive environment.
- Robotic-Assisted Therapy: Robotic devices guide patient limbs through repetitive movement patterns, offering high-intensity training to enhance motor recovery and neuroplasticity.
- Virtual Reality (VR) Rehabilitation: VR environments engage patients in interactive tasks that simulate daily life scenarios, boosting motivation, adherence, and sensorimotor integration.
Exercise Therapies
- Range-of-Motion (ROM) Exercises: Passive and active ROM movements maintain joint flexibility, prevent contractures, and prepare muscles for strength training.
- Strength Training: Progressive resistance exercises using weights or resistance bands target weakened muscle groups to increase force production and functional capacity.
- Endurance Training: Low to moderate intensity aerobic activities (e.g., stationary cycling) improve cardiovascular fitness, reducing fatigue and enhancing tolerance for daily activities.
- Coordination Exercises: Activities like finger-to-nose or heel-to-shin training refine fine motor control and inter-limb coordination critical for tasks such as writing and dressing.
- Balance Training: Exercises on unstable surfaces (e.g., wobble boards) challenge postural control, reducing fall risk and improving gait stability.
Mind-Body Therapies
- Motor Imagery: Patients mentally rehearse movements without actual execution, activating similar brain regions involved in motor control, which can translate to improved physical performance.
- Yoga: This combines gentle postures, breath control, and mindfulness to enhance flexibility, reduce spasticity, and promote relaxation.
- Tai Chi: Slow, flowing movements emphasize weight shifting, postural control, and mindful attention, improving balance and proprioception.
- Mindfulness Meditation: Focused awareness practices reduce stress, improve coping with disability, and may positively influence neural plasticity.
- Progressive Muscle Relaxation: Systematic tension and relaxation of muscle groups decreases overall muscle tone, aiding in spasticity management and stress reduction.
Educational Self-Management
- Patient Education Workshops: Structured sessions teach patients about stroke mechanisms, risk factor control, and self-monitoring to foster engagement and adherence to rehabilitation.
- Home Exercise Programs: Individualized exercise plans with clear instructions empower patients to continue therapy independently, reinforcing gains made in the clinic.
- Goal-Setting Strategies: Collaborative goal definition between patient and therapist increases motivation, tracks progress, and tailors interventions to personal priorities.
- Pain and Spasticity Diaries: Logging symptoms and triggers helps patients and clinicians adjust therapy plans and medication dosing for optimal symptom control.
- Peer Support Groups: Group meetings with fellow survivors provide emotional support, share practical coping strategies, and enhance self-efficacy through community.
