Pure Motor Hemiparesis (PMH) is a neurological condition in which a person suddenly develops weakness or partial paralysis on one entire side of the body—including the face, arm, and leg—without any loss of sensation, vision, coordination, or higher mental function. In other words, the muscles on one side simply do not obey normal commands, yet touch, temperature, pain, and balance feel perfectly normal. PMH is the most common of the “lacunar stroke syndromes,” meaning it usually happens when a tiny, deep stroke damages the internal capsule, corona radiata, or basis pontis—the brain’s main “wiring bundles” that carry motor signals from the cortex to the spinal cord.
Pure Motor Hemiparesis is the commonest of the “lacunar-stroke” syndromes. It happens when a pinpoint blockage cuts the blood flow to deep motor pathways in the brain—most often the posterior limb of the internal capsule, corona radiata, or the ventral pons. The damage spares the sensory tracts and the thinking parts of the cortex, so the hallmark is one-sided weakness (face + arm + leg) with no numbness, no speech loss, and no vision changes. PMH accounts for roughly half of all lacunar strokes and usually signals a tiny (≤15 mm) infarct fed by a single perforating artery. Because the injury is small and the cortex is intact, recovery can be surprisingly good, especially if therapy begins early. ncbi.nlm.nih.govradiopaedia.org
Think of the motor pathway as a three-lane highway: brain cortex → internal capsule/brain-stem relay → spinal cord. In PMH, a microscopic clot blocks one lane in the relay station. High blood pressure, diabetes, smoking, high “bad” cholesterol, and aging stiffen the tiny perforating arteries until their walls thicken (lipohyalinosis) or collect micro-atheroma. A sudden spike in pressure or a small embolus then plugs the narrowed lumen, starving the motor fibers of oxygen. Because neighbor tracts are tightly packed, even a pepper-seed-sized infarct can paralyze half the body. Yet the sensory and language lanes run in different bundles, so they stay open, leaving a “pure” motor picture. Prognosis is better than large-artery strokes; many patients regain full function within weeks if secondary strokes are prevented. wjgnet.comahajournals.org
Pathophysiology
Under a microscope, the brain pathways that control voluntary movement look like tightly packed telephone cables. A lacunar infarct (tiny ischemic stroke) the size of a pea can disconnect thousands of these fibers at once. Because the sensory wires lie in separate tracts, they stay intact; because the cognitive and language centers are elsewhere, thinking remains clear. The result is a pure motor deficit. Hypertension, diabetes, and aging wear down the penetrating arterioles that feed these deep structures, creating lipohyalinosis (fat-and-protein scarring) and microatheromas (mini-plaques). When one of those arterioles blocks, blood flow stops, neurons die within minutes, and contralateral weakness appears. Occasionally, a small hemorrhage, demyelinating plaque, abscess, or tumor in the same strategic spot mimics the classic lacunar picture.
Clinically, PMH presents abruptly (seconds to minutes) or stuttering over hours; symptoms peak early and often improve with therapy, yet residual weakness may persist. Because the lesion is compact, patients rarely deteriorate into coma, and mortality is low compared with big-vessel strokes. However, PMH carries significant disability: hand dexterity, walking speed, and facial expression can remain impaired, affecting independence, employment, and psychological well-being.
Main Types of Pure Motor Hemiparesis
Although PMH is defined by its purity of motor loss, clinicians recognize several practical sub-types:
Acute Lacunar PMH – sudden onset, classic internal-capsule infarct; most common presentation.
Pontine PMH – weakness plus mild dysarthria when a small infarct hits the basis pontis; sometimes called “dysarthria-clumsy hand” variant.
Progressive (Marching) PMH – stepwise worsening over hours to days, suggesting ongoing thrombotic occlusion or edema around the core.
Transient PMH (TIA form) – symptoms resolve within 24 h; high warning value for impending stroke.
Hemorrhagic PMH – tiny hypertensive bleed instead of ischemia; initial presentation identical, but CT shows blood.
Non-vascular PMH-mimics – plaques in multiple sclerosis, metastatic deposits, abscesses, or cavernous malformations that compress corticospinal tracts without affecting sensory fibers.
Childhood PMH – rare lacunar strokes in sickle-cell disease or congenital vasculopathies.
Post-ictal Todd’s Paresis – reversible weakness after a seizure; clinically pure motor but temporary and cortical in origin.
Variants and sub-types of PMH
Although clinicians label all pure motor strokes under one banner, subtle differences help localise the injury:
Internal-capsule PMH – classic picture; dense weakness of face, arm and leg. stanfordmedicine25.stanford.edu
Basis-pontis PMH – often milder facial weakness but identical limb pattern; sometimes transient diplopia because the lesion lies near cranial-nerve fibres.
Corona-radiata PMH – weakness may spare the face because fibres have not yet converged.
Thalamic-capsular PMH – rare; may pick up mild sensory loss hours later as oedema spreads.
Reversible PMH (TIA pattern) – symptoms resolve completely within 24 h; warns of an impending lacunar infarct.
Progressive (stuttering) PMH – stepwise worsening over hours to days; reflects ongoing vessel occlusion or peri-infarct oedema.
Causes of PMH
Below are twenty distinct etiologies, each described in a full paragraph for clarity:
Chronic Hypertension-Induced Lacunar Infarct
High blood pressure stiffens and scars deep perforating arterioles, predisposing them to sudden closure and a pea-sized infarct in the internal capsule.Type 2 Diabetes Mellitus
Long-standing hyperglycemia accelerates small-vessel atherosclerosis and lipohyalinosis, doubling lacunar stroke risk.Microatheroma of the Lenticulostriate Arteries
Tiny cholesterol plaques form right at the arterial origin off the middle cerebral artery, acting like corks in narrow wine bottles.Cardio-embolic Shower of Micro-clots
Atrial fibrillation or a mechanical valve can flick microscopic clots deep into the brain, causing multifocal lacunes.Cerebral Amyloid Angiopathy
In older adults, β-amyloid deposition weakens vessel walls; rupture or occlusion in the centrum semiovale may yield a “pure motor” picture.Hypertensive Micro-hemorrhage
A pinpoint bleed in the internal capsule can compress motor fibers exactly like an ischemic lesion.Multiple Sclerosis Plaque
Demyelination occasionally targets the posterior limb of the internal capsule, sparing sensory pathways and leading to focal contralateral weakness.Moyamoya Disease
Progressive stenosis of the intracranial carotids spawns fragile collaterals; children and young adults may suffer lacunar-like strokes during hypotension.Vasculitic Disorders (e.g., Primary CNS Vasculitis, Lupus)
Inflammatory infiltration of vessel walls narrows arteriolar lumens, causing deep ischemic pen-strokes on MRI.Sickle-Cell Disease
Sickled erythrocytes clog deep perforators, especially in adolescents, and produce pure motor deficits.Cavernous Malformation Rupture
These berry-like vascular tangles can bleed silently; a small hemorrhage in the internal capsule mimics lacunar stroke.Metastatic Brain Tumor (Strategic Compression)
Tiny deposits from lung or breast cancers can sit precisely on descending fibers.Brain Abscess
Bacterial or fungal abscess in the basal ganglia causes mass effect and edema, blocking motor tracts.Primary Brain Neoplasm (e.g., Glioma)
Low-grade gliomas expand slowly but, when located deep, they interrupt corticospinal signaling.Severe Hypoglycemia
Critically low glucose can create regional cytotoxic edema in the internal capsule region, leading to reversible PMH.Hyperosmolar Hyperglycemic State (HHS)
Sudden shifts in plasma osmolarity injure vulnerable white-matter tracts, especially in the elderly.Migraine with Aura-Related Stroke (Migrainous Infarction)
Rarely, prolonged vasospasm during hemiplegic migraine leaves a permanent lacune.Radiation-Induced Small-Vessel Disease
Cranial irradiation for leukemia or nasopharyngeal carcinoma accelerates arteriolar fibrosis and late-onset lacunes.Traumatic Shearing Injury
Diffuse axonal injury can preferentially tear fibers in the internal capsule, causing pure weakness.Endocarditis-Associated Septic Emboli
Minute infected clots can lodge in deep arteries and produce lacunar-sized infarcts along corticospinal tracks.
Common Symptoms and Functional Complaints
Sudden Weakness of Face, Arm, and Leg on One Side – hallmark sign noted by patients or observers.
Slurred Speech (Mild Dysarthria) – due to facial and tongue weakness rather than language dysfunction.
Hand Clumsiness – difficulty buttoning shirts, writing, or handling utensils.
Dragging Foot or Toe Scuffing – gait becomes slow, with leg circumduction.
Facial Droop – asymmetry when smiling or showing teeth.
Difficulty Gripping Objects – cups, pens, and phone slip from the hand.
Fatigue During Simple Tasks – brushing hair or climbing stairs feels exhausting.
Loss of Fine Motor Skills – zipper manipulation and coin counting deteriorate.
Impaired Balance During Fast Turns – weakness rather than vestibular loss causes subtle staggering.
Brisk Reflexes (Hyperreflexia) – noticed by clinicians but sometimes felt as “jerky” movements by patients.
Muscle Stiffness (Spasticity) Over Weeks – evolving tone makes joints feel tight.
Foot Drop – inability to dorsiflex the ankle fully, leading to tripping.
Difficulty Raising Eyebrow or Closing Eye Tightly – facial nerve fibers involved centrally.
Chewing Fatigue – mastication muscles tire easily on the affected side.
Mild Emotional Lability – laughing or crying more easily, linked to corticobulbar fiber disruption.
Shoulder Pain and Subluxation – secondary to flaccid paralysis and poor joint support.
Speech Fatigue – sentences become short because tongue muscles weaken.
Hand Fasciculations After Weeks – small visible twitches from denervated muscle units.
Cold Intolerance in Weak Limb – reduced motor activity lowers local heat generation.
Depressive Mood – psychosocial impact of sudden disability.
Diagnostic Tests
A. Physical Examination-Based Tests
Motor Power Grading (Medical Research Council Scale) – Clinician asks the patient to move each limb against resistance and grades strength from 0 to 5.
Pronator Drift Test – Arms held out with palms up; a weak arm slowly pronates and drifts downward.
Facial Muscle Assessment – Patient raises eyebrows, smiles, and puffs cheeks; asymmetry points to central facial palsy.
Deep Tendon Reflexes – Reflex hammer taps reveal brisk knee-jerk or ankle-jerk on the weak side, confirming an upper-motor-neuron pattern.
Babinski Sign – Stroking the sole causes upward big-toe extension, indicating corticospinal tract injury.
Spastic Tone Evaluation (Passive Range of Motion) – Resistance increases with faster stretch, typical of post-stroke spasticity.
Gait Observation – Hemiparetic gait shows leg circumduction and reduced arm swing on the affected side.
Shoulder Subluxation Palpation – Gap between acromion and humeral head suggests flaccid paralysis leading to joint drop.
B. Manual or Bedside Functional Tests
Nine-Hole Peg Test – Times how quickly the patient can place and remove pegs; excellent for fine motor tracking.
Timed Up-and-Go Test (TUG) – Measures seconds to rise from a chair, walk 3 m, turn, return, and sit; prolongation reflects leg weakness and balance loss.
Finger-to-Nose Test (for Dysmetria vs. Weakness) – Distinguishes cerebellar ataxia from pure motor impairment.
Rapid Alternating Movements (Diadochokinesia) – Palm flipping speed slows on the paretic side.
Hand Dynamometer Grip Strength – Quantifies force in kilograms; tracks progress in rehab.
Ten-Meter Walk Test – Records comfortable and maximal walking speed; widely used to set physiotherapy goals.
Functional Reach Test – Measures how far a patient can reach forward without stepping; decreased reach signals trunk weakness.
Heel-knee-Shin Test – Helps rule out cerebellar problems; in PMH, weakness, not incoordination, limits performance.
C. Laboratory and Pathological Tests
Complete Blood Count (CBC) – Detects anemia or infection that could worsen cerebral oxygen delivery.
Fasting Glucose and HbA1c – Identifies diabetes, a major lacunar stroke risk factor.
Comprehensive Metabolic Panel (CMP) – Checks kidney and liver function, electrolytes, and calcium; abnormalities can mimic or aggravate stroke.
Lipid Profile – High LDL and triglycerides promote atherosclerosis in small and large vessels.
Coagulation Panel (PT, aPTT, INR) – Essential before thrombolysis and to uncover clotting disorders.
Erythrocyte Sedimentation Rate (ESR) and C-Reactive Protein (CRP) – Elevated markers hint at vasculitis or infection.
Serum Homocysteine – High levels damage endothelium and raise stroke risk, especially in young patients.
Antiphospholipid Antibody Screen – Detects autoimmune hypercoagulable state leading to recurrent lacunes.
D. Electrodiagnostic and Vascular Physiology Tests (8)
Electroencephalography (EEG) – Rules out focal seizures or post-ictal weakness masquerading as PMH.
Nerve Conduction Studies (NCS) – Confirms that peripheral nerves are intact; differentiates central from peripheral weakness.
Electromyography (EMG) – Detects spontaneous muscle activity and motor-unit recruitment; useful when diagnosis is uncertain.
Somatosensory Evoked Potentials (SSEP) – Sensory pathways usually normal in PMH; normal SSEPs support the “pure” motor diagnosis.
Motor Evoked Potentials via Transcranial Magnetic Stimulation (TMS) – Quantifies corticospinal conduction time and recovery potential.
Transcranial Doppler (TCD) Ultrasound – Measures blood flow velocity in basal arteries; micro-embolic signals or high velocities suggest upstream stenosis.
Holter Monitoring (24- to 72-hour ECG) – Detects intermittent atrial fibrillation sending micro-clots to deep perforators.
Tilt-Table Test – In young patients with suspected autonomic dysfunction leading to hypotensive lacunes.
E. Imaging Tests
Non-contrast CT Head – First-line to exclude hemorrhage; early lacunes may be invisible, but CT still rules out bleed.
CT Angiography (CTA) – Visualizes large and medium intracranial vessels for thrombus or stenosis.
MRI Brain with Diffusion-Weighted Imaging (DWI) – Gold standard; bright “dot” in the internal capsule within minutes of symptom onset confirms diagnosis.
Magnetic Resonance Angiography (MRA) – Non-invasive vessel mapping to detect narrowing of the carotid siphon or MCA trunk.
Carotid Duplex Ultrasound – Screens for extracranial carotid disease contributing to lacunar-like events.
CT Perfusion (CTP) – Shows core-penumbra mismatch; in lacunes, the core is tiny but CTP helps rule out larger stroke syndromes.
Positron Emission Tomography (PET) – Research tool that maps glucose metabolism, occasionally used to differentiate tumor from infarct.
Single Photon Emission Computed Tomography (SPECT) Perfusion Scan – Demonstrates regional cerebral blood flow deficits when MRI is contraindicated.
Non-Pharmacological Treatments
(Grouped for easy reading; each paragraph names the therapy, goal, and how it works)
A. Physiotherapy & Electro-physical Therapies
Early Mobilization & Task-Specific Training – Getting out of bed ≤ 24 h (when medically safe) “wakes up” dormant motor circuits and prevents de-conditioning by repeating real-life tasks such as standing up, stepping, or grasping.

Mirror Therapy – A mirror placed at midline shows the reflection of the healthy hand moving; the brain “believes” the paretic hand is active, boosting motor cortex excitability and reducing learned non-use. pubmed.ncbi.nlm.nih.gov
Neuromuscular Electrical Stimulation (NMES) – Surface electrodes deliver low-level pulses (20–50 Hz, 30 min) that trigger muscle contractions, strengthen weak muscles, and promote synaptic sprouting. pubmed.ncbi.nlm.nih.gov
Functional Electrical-Stimulation Cycling – NMES synchronized to a stationary cycle aids reciprocal leg movement, improving gait endurance.
Robot-Assisted Arm Training – Exoskeletons guide repetitive reach-and-grasp motions, providing high-dose, precise practice.
Body-Weight-Supported Treadmill Training – A harness unloads ≤ 40 % body weight so patients can rehearse symmetrical stepping before they can bear full weight.
Virtual-Reality (VR) Practice – Gamified VR tasks immerse patients in engaging environments that reward accurate reaches or steps, reinforcing plasticity.
Repetitive Transcranial Magnetic Stimulation (rTMS) – Magnetic pulses (1 Hz inhibitory to healthy side or 10 Hz excitatory to affected side) balance inter-hemispheric inhibition and improve upper-limb dexterity. pubmed.ncbi.nlm.nih.gov
Transcranial Direct Current Stimulation (tDCS) – A gentle 1–2 mA current applied via scalp electrodes primes neurons for learning when paired with therapy. pubmed.ncbi.nlm.nih.govpubmed.ncbi.nlm.nih.gov
Biofeedback (EMG or Force-Plate) – Real-time graphs of muscle firing or weight shift teach patients to recruit weak muscles consciously.
Whole-Body Vibration – Standing on a 20–30 Hz platform activates muscle spindles, temporarily reducing spasticity and improving balance.

Proprioceptive Neuromuscular Facilitation (PNF) Stretching – Therapist-guided diagonal patterns reinforce coordinated muscle firing.
EMG-Triggered Neuromuscular Stimulation – The stimulator monitors tiny voluntary EMG signals and adds an electric boost only when the patient initiates effort, fostering motor relearning.
B. Exercise-Based Therapies
Progressive Resistance Training – Low-load, high-repetition sets (e.g., 3 × 15) safely strengthen paretic limbs without spiking blood pressure.
Circuit Class Training – Small-group stations combine aerobic and task drills, increasing adherence and social motivation.
Incremental Treadmill Aerobic Training – 40–60 % heart-rate reserve for 20–30 min, three times weekly, enhances cardiovascular fitness that feeds brain recovery.
Nordic Walking – Poles add upper-body involvement, improve posture, and challenge balance outdoors.
Home-Based Tele-rehab Exercise Apps – Video-guided programs ensure daily practice when clinic visits are limited.
C. Mind-Body Approaches
Yoga (Chair or Mat) – Slow postures plus diaphragmatic breathing lower stress, gently stretch tight muscles, and improve trunk control.
Tai Chi – Flowing weight-shifts retrain ankle and hip strategies, cutting fall risk.
Mindfulness-Based Stress Reduction – Guided meditation lowers cortisol, indirectly benefitting neuroplasticity.
Music-Supported Therapy – Playing simple keyboard sequences recruits auditory–motor coupling networks, enhancing fine-motor control.

When Should You See a Doctor?
Immediately if you notice sudden weakness, facial droop, or slurred speech—call emergency services.
Within 24 h for any new numbness, clumsiness, or balance loss even if it improves (TIAs warn of a bigger stroke).
Urgently if blood pressure stays > 180/110 mm Hg despite rest or you develop severe headaches, visual changes, or chest pain.
Promptly if spasticity stiffens joints or pain limits therapy; early intervention prevents contractures.
What to Do & What to Avoid

Do monitor BP at home; avoid excess salt (> 5 g/day).
Do eat fish twice weekly; avoid trans-fats and ultra-processed snacks.
Do keep vaccines up to date; avoid flu—fever worsens stroke outcomes.
Do use ankle-foot orthoses or canes early for safety; avoid unassisted stairs until cleared.
Do ask about mood—treat depression; avoid isolation.
Do schedule dental checks; avoid oral infections that can spike inflammation.
Do wear compression stockings on long trips; avoid dehydration and immobility.
Do carry a medication list; avoid herbal remedies that may thin blood without disclosure.
Frequently Asked Questions
Is PMH the same as a “mini-stroke”? – PMH is a full stroke but in a deep, small area; symptoms can be severe yet recovery potential is high.
Why didn’t I lose sensation? – The clot hit only motor fibers; sensory tracts lie in other bundles.
Can I drive again? – Many regain safe driving within 3–6 months after a medical and occupational-therapy road test.
Will the weakness return? – Once stable, the same deficit usually won’t relapse, but new strokes can happen without prevention.
Is recovery possible after a year? – Yes; the brain stays plastic, and robotics, rTMS, or DBS may still yield gains.
Can supplements replace medicines? – No. Omega-3s or CoQ10 support health but do not thin clots like aspirin or reopen arteries like tPA.
Is spasticity permanent? – Not always; early stretching, NMES, and baclofen (oral / pump) can soften tone.
What’s the survival rate? – Five-year survival after a first lacunar stroke is ~85 %; risk depends on age and risk-factor control. ahajournals.org
Do statins cause memory loss? – Large reviews show no definitive link; benefits outweigh rare side-effects.
Can high blood pressure alone cause PMH? – Yes; chronic hypertension is the number-one culprit for lacunar infarcts.
Is tPA safe for seniors over 80? – Modern guidelines allow alteplase up to 4.5 h regardless of age if criteria are met; bleeding risk rises slightly.
How soon should therapy start? – Within 48 h for mobilization and within 2 weeks for high-intensity upper-limb programs like CIMT.
Will stem-cell therapy be widely available? – Trials are promising but still experimental; discuss only in specialized centers.
Can I prevent bone loss after the stroke? – Weight-bearing exercises and bisphosphonates such as Alendronate help.
Is a “silent” lacunar stroke serious? – Yes; even silent lesions double future stroke and dementia risk, so prevention matters.
