Practice Medicine Video-Based Questions to Crack NEET PG 2026 is designed to help aspirants become familiar with the evolving pattern of clinical questions. It focuses on recognising important physical examination findings, movement disorders, neurological signs, and bedside examination techniques that may appear in NEET PG.
By understanding how clinical videos are interpreted, candidates can improve their approach to solving medicine-based video MCQs.

Video-based questions encourage candidates to identify real clinical signs rather than relying only on memorisation. Recognising visual findings during physical examination helps improve clinical reasoning and enables candidates to answer scenario-based medicine questions more effectively.
Key reasons these questions are important include:
Strengthen clinical observation skills: They test your ability to recognise physical signs, movement disorders, and examination findings demonstrated in patients.
Promote concept-based learning: Instead of recalling isolated facts, candidates learn to interpret clinical findings in the correct medical context.
Improve application in clinical scenarios: Identifying visual cues during patient examination can help solve medicine-based MCQs that require practical interpretation.
Medicine video-based questions can assess candidates on clinical findings from multiple systems. Being familiar with these areas can help improve the interpretation of patient examination videos and support accurate clinical decision-making.
The key systems include:
Cardiology
Respiratory Medicine
Neurology
Clinical Examination Signs
Each of these systems may include video-based clinical findings that require candidates to identify physical signs, interpret examination findings, and apply relevant medical concepts to answer questions accurately.
The following video-based questions assess your ability to identify clinical signs, interpret patient findings, and apply medical knowledge in practical scenarios. Watch each video carefully before answering the questions.
A) Resting tremor
B) Chorea
C) Asterixis
D) Intention tremor
Mechanism: Asterixis (commonly known as a "flapping tremor") is physically characterized by a sudden, brief loss of postural muscle tone followed by a rapid, compensatory recovery movement.
Clinical Assessment: It is classically elicited by asking the patient to extend their arms straight out in front of them with their wrists hyperextended (dorsiflexed), causing a visible lapse in posture that resembles a bird flapping its wings.
Systemic Significance: Asterixis is a hallmark clinical sign of metabolic encephalopathy, most frequently seen in hepatic encephalopathy (due to liver failure) but can also present in uremic encephalopathy (renal failure) or severe hypercapnia (CO2 narcosis).
Why the other options are incorrect:
A) Resting tremor: This type of tremor occurs when a limb is fully relaxed and supported against gravity, most notably seen in Parkinson's disease.
B) Chorea: This refers to random, continuous, jerky, and purposeless involuntary movements that flow irregularly from one body part to another.
D) Intention tremor: This occurs strictly during a goal-directed, voluntary movement (such as touching one's nose), typically indicating cerebellar disease.
A) Parkinson's disease
B) Hepatic encephalopathy
C) Cerebellar stroke
D) Essential tremor
Mechanism: Asterixis or flapping tremor occurs primarily in patients with metabolic brain disorders (metabolic encephalopathies) where toxic metabolites impair the normal function of the brain and basal ganglia.
Clinical Correlation: In typical clinical practice, it is most classically and frequently encountered in patients suffering from hepatic encephalopathy secondary to severe liver dysfunction or failure (driven by toxin buildup like ammonia).
Other Causes: Beyond hepatic disorders, asterixis can also be triggered by other severe metabolic derangements, such as uremic encephalopathy (kidney failure), hypercapnic encephalopathy (CO2 narcosis), and severe hyponatremia.
Why the other options are incorrect:
A) Parkinson's disease: This condition is characterized by a resting tremor (such as a pill-rolling tremor) and bradykinesia rather than a metabolic flap.
C) Cerebellar stroke: Damage to the cerebellum leads to coordination issues and an intention tremor (action tremor unmasked during movement).
D) Essential tremor: This is a distinct movement disorder typically presenting as a progressive, symmetric postural/kinetic tremor usually affecting the hands during actions, and it is not a sign of metabolic encephalopathy.
A) It represents a classic Upper Motor Neuron (UMN) sign and is best evaluated while the patient actively protrudes the tongue.
B) It represents a classic Lower Motor Neuron (LMN) sign and is best evaluated while the tongue is resting on the floor of the mouth.
C) It is an intention tremor indicating Cerebellar Dysfunction (such as cerebellar stroke).
D) It is a pathognomonic sign of Neuromuscular Junction (NMJ) dysfunction, such as Myasthenia Gravis.
Mechanism: The fine, involuntary, rippling movements described across the surface are tongue fasciculations. Fasciculations and muscle wasting (atrophy) are primary hallmarks of a lower motor neuron (LMN) lesion affecting the motor units.
Neuroanatomy: In the context of the tongue, fasciculations imply damage to the lower motor neurons running through the Hypoglossal Nerve (Cranial Nerve XII) or its nucleus in the medulla.
Clinical Assessment Pearl: Fasciculations must be evaluated while the tongue rests entirely relaxed inside the floor of the mouth. Active protrusion of the tongue contracts the muscles and introduces normal physiologic tremors, which can mimic or falsely cloud the diagnosis of true fasciculations.
Why the other options are incorrect:
A) Upper Motor Neuron (UMN) sign: UMN lesions targeting the tongue cause spasticity, slowness of movement, and hypertonia rather than fasciculations or marked wasting.
C) Cerebellar Dysfunction: Cerebellar damage results in an intention tremor (action tremor), which typically unmasks during purposeful, voluntary movement (e.g., protrusion) and would not present as continuous rippling at rest.
D) Neuromuscular Junction (NMJ) dysfunction: NMJ disorders like Myasthenia Gravis lead to muscle fatigue with repetitive use but typically do not cause true muscular fasciculations or severe neurogenic atrophy.
Primary lateral sclerosis
Amyotrophic lateral sclerosis
MCA stroke
Lathyrism
Clinical Context: This question builds directly upon the previous slide (VBQ-3), where the patient demonstrated marked tongue fasciculations—a classic indicator of a lower motor neuron (LMN) lesion.
Mechanism: Among the given options, Amyotrophic lateral sclerosis (ALS) is a mixed motor neuron disease that selectively targets and destroys both upper motor neurons (UMN) and lower motor neurons (LMN). Out of the listed conditions, it is the only one capable of causing the LMN damage responsible for producing tongue fasciculations.
Why the other options are incorrect:
1. Primary lateral sclerosis: This is a pure upper motor neuron (UMN) disease that affects the lateral corticospinal tracts, causing spasticity rather than LMN fasciculations.
3. MCA stroke: A middle cerebral artery stroke causes damage to cortical upper motor neurons, leading to a UMN type of muscle weakness and spasticity, not rest-associated muscle fasciculations.
4. Lathyrism: This neurotoxic condition acts as a pure upper motor neuron disease, primarily causing progressive spastic paraparesis.
Curtain sign
Peak sign
Cogan sign
Corrigan's sign
Mechanism: In Myasthenia Gravis, repetitive muscle use worsens fatigue, whereas resting a muscle briefly restores its strength.
The Sign: When a patient is asked to look down for 10 to 12 seconds, the levator palpebrae superioris (eyelid-elevating muscle) gets to rest. When the patient suddenly shifts their gaze back to the central eye-level position, the newly rested neuromuscular junctions transmit signals exceptionally well, causing the upper eyelid to twitch and briefly overshoot upward before fatiguing back down to its baseline state. This presentation is known as Cogan's lid twitch sign.
Why the other options are incorrect:
1. Curtain sign: This occurs when an examiner manually lifts one ptotic eyelid, causing a drop (droop) like a closing curtain in the opposite eyelid due to Hering's Law of equal innervation.
2. Peak sign: This occurs when a patient tries to close their eyes tightly, but the orbicularis oculi muscle quickly fatigues, causing the eyelids to separate slightly so the white sclera "peeks" through.
4. Corrigan's sign: This is entirely unrelated to myasthenia gravis; it refers to the "dancing carotids" seen in the neck of patients with aortic regurgitation.
