Pediatric Rehabilitation Indian Medical PG Practice Questions and MCQs
Question 1: All are characteristic features of cerebral palsy except
- A. Hypotonia
- B. Epilepsy
- C. Spasticity
- D. Erb's palsy (Correct Answer)
Explanation: ***Erb's palsy*** - **Erb's palsy** is a form of brachial plexus palsy, characterized by injury to the **upper brachial plexus** (C5-C6 nerve roots), typically occurring during birth. - It results in a characteristic **"waiter's tip" position** of the arm and is a distinct peripheral nerve injury, not a characteristic feature of **cerebral palsy**, which is a central neurological disorder. *Hypotonia* - While many forms of cerebral palsy present with **spasticity**, some individuals, particularly those with **ataxic cerebral palsy** or specific types of dyskinetic cerebral palsy, can exhibit **hypotonia** (low muscle tone). - Hypotonia can also be an early manifestation before the development of more prominent hypertonia or spasticity, making it an associated feature. *Epilepsy* - **Epilepsy** and seizure disorders are common co-morbidities seen in children with **cerebral palsy**, particularly in those with severe brain damage or certain types of CP. - The underlying brain injury that causes cerebral palsy can also disrupt normal electrical activity in the brain, leading to seizures. *Spasticity* - **Spasticity** is the most common motor type of **cerebral palsy**, affecting approximately 80% of individuals. - It is characterized by **increased muscle tone** and **hyperreflexia**, resulting in stiff, tight muscles and exaggerated reflexes, due to damage to the motor cortex or pyramidal tracts.
Question 2: Best therapy suited to teach daily life skills to a child with intellectual disability:
- A. Applied Behavior Analysis (ABA) (Correct Answer)
- B. Cognitive Behavioral Therapy (CBT)
- C. Social skills training
- D. Self-instructional training
Explanation: **Applied Behavior Analysis (ABA)** - **ABA** is a highly structured, evidence-based therapy that focuses on teaching specific skills by breaking them down into smaller steps and using **positive reinforcement**. - It is particularly effective for children with intellectual disabilities in acquiring **adaptive daily living skills**, communication, and social behaviors. *Cognitive Behavioral Therapy (CBT)* - **CBT** primarily targets changing negative thought patterns and behaviors, requiring a level of abstract reasoning that may be challenging for children with significant intellectual disabilities. - While it can be adapted, its core methods rely on cognitive processes that might not be the most direct approach for teaching basic daily life skills to a mentally challenged child. *Social skills training* - **Social skills training** focuses specifically on improving social interactions and communication within social contexts. - While important for overall development, it is a subcomponent of broader skill development and may not directly address all aspects of **daily living skills** in a comprehensive manner. *Self-instructional training* - **Self-instructional training** involves teaching individuals to guide themselves through tasks using internal speech or self-talk, which relies on a child's ability to internalize and follow complex verbal instructions. - This approach might be too cognitively demanding for a child with significant developmental delays when the primary goal is mastering basic, functional daily life skills.
Question 3: All of the following are affected in Erb's palsy EXCEPT
- A. Dorsal scapular nerve
- B. Suprascapular nerve
- C. Lower trunk of brachial plexus (Correct Answer)
- D. Upper trunk of brachial plexus
Explanation: ***Lower trunk of brachial plexus*** - Erb's palsy primarily involves the **upper trunk** of the brachial plexus (C5-C6 nerve roots), which affects muscles innervated by these roots. - The **lower trunk** (C8-T1 nerve roots) is typically spared in Erb's palsy, distinguishing it from **Klumpke's palsy**. *Dorsal scapular nerve* - The dorsal scapular nerve originates from the **C5 root of the brachial plexus** and innervates the **rhomboids** and **levator scapulae**. - As Erb's palsy involves the C5 root, the dorsal scapular nerve and its associated muscles are commonly affected. *Suprascapular nerve* - The suprascapular nerve arises from the **upper trunk** of the brachial plexus (C5-C6) and innervates the **supraspinatus** and **infraspinatus** muscles. - Damage to the upper trunk in Erb's palsy directly impacts the function of the suprascapular nerve. *Upper trunk of brachial plexus* - Erb's palsy is specifically defined by an injury to the **upper trunk** of the brachial plexus, involving the C5 and C6 nerve roots. - This damage leads to weakness in muscles such as the **deltoid**, **biceps**, and **brachialis**, resulting in the characteristic **"waiter's tip"** posture.
Question 4: A 4-year-old male child presents with muscle weakness. His mother reports that her child has difficulty in climbing stairs and getting up from the floor. On muscle biopsy, small degenerated muscle fibers and absence of dystrophin were found. What is the diagnosis?
- A. Myotonic dystrophy
- B. Becker's muscle dystrophy
- C. Limb-girdle muscular dystrophy
- D. Duchenne muscular dystrophy (Correct Answer)
Explanation: ***Duchenne muscular dystrophy*** - The classic presentation of a young boy with **progressive muscle weakness**, difficulty climbing stairs (**Gowers' sign**), and **absent dystrophin** on muscle biopsy is characteristic of Duchenne muscular dystrophy. - It is an **X-linked recessive disorder** that leads to severe muscle degeneration and weakness due to a complete lack of functional dystrophin protein. *Myotonic dystrophy* - This condition is characterized by **myotonia** (delayed relaxation of muscles after contraction) and typically affects adults, although congenital forms exist. - While it causes muscle weakness, the primary differentiating feature of **myotonia** and its later onset are not present in this case. *Becker's muscle dystrophy* - Becker's muscular dystrophy (BMD) is also an X-linked recessive disorder and a milder form of muscular dystrophy, caused by a **reduced but still functional dystrophin** protein. - Patients with BMD typically present later in childhood or adolescence with slower progression and **some dystrophin** presence, unlike the absent dystrophin and early onset here. *Limb-girdle muscular dystrophy* - This is a group of muscular dystrophies that primarily affect the **pelvic and shoulder girdle muscles**. - It can present with similar weakness, but the **complete absence of dystrophin** found on biopsy points specifically to Duchenne muscular dystrophy, not typical limb-girdle dystrophy, which involves other genetic defects.
Question 5: Who devised the correction of CTEV by serial casting?
- A. Gerhardt Kuntscher
- B. Gavril Ilizarov
- C. Hugh Owen Thomas
- D. Ignacio Ponseti (Correct Answer)
Explanation: ***Ignacio Ponseti*** - Dr. Ignacio Ponseti developed the **Ponseti method**, a non-surgical technique for correcting **congenital talipes equinovarus (CTEV)**, commonly known as clubfoot. - This method involves a series of **gentle manipulations** and **serial casting**, followed by the use of a foot abduction brace. *Gerhardt Kuntscher* - **Gerhardt Kuntscher** was a German surgeon known for developing the **intramedullary nail** for fixing long bone fractures. - His contributions revolutionized the surgical management of fractures, but he did not develop the method for CTEV correction. *Gavril Ilizarov* - **Gavril Ilizarov** was a Soviet orthopedic surgeon famous for inventing the **Ilizarov apparatus**, an external fixator used for limb lengthening and complex fracture treatment. - His work focused on osteogenesis and bone regeneration, not the non-surgical correction of clubfoot. *Hugh Owen Thomas* - **Hugh Owen Thomas** was a Welsh orthopedic surgeon regarded as the "father of British orthopaedic surgery," known for the development of the **Thomas splint**. - His contributions were primarily in managing fractures and tuberculosis of the joints, independent of CTEV correction techniques.
Question 6: Which of the following is a symptom of cerebral palsy?
- A. Microcephaly
- B. Ataxia (Correct Answer)
- C. Hypotonia
- D. Flaccid paralysis
Explanation: ***Ataxia*** - **Ataxia** (lack of voluntary coordination of muscle movements) is one of the primary **motor symptoms of cerebral palsy**, specifically seen in **ataxic cerebral palsy** which accounts for 5-10% of CP cases. - Ataxic CP presents with **poor coordination, tremors, and balance difficulties**, representing a distinct motor presentation pattern. - It is a direct neurological symptom resulting from **cerebellar or basal ganglia involvement**. *Hypotonia* - **Hypotonia** (decreased muscle tone) can occur in cerebral palsy, particularly as an **early finding in infants**. - However, hypotonia often **evolves into other motor patterns** (spasticity, dyskinesia) as the child develops, making it less specific as a defining symptom. - While present in some forms, it's more transitional than a consistent motor symptom across CP types. *Microcephaly* - **Microcephaly** (abnormally small head) is not a symptom of cerebral palsy itself, but rather a potential **associated condition or underlying cause**. - It suggests **abnormal brain development** which *could* lead to cerebral palsy, rather than being a neurological motor symptom *of* CP. *Flaccid paralysis* - **Flaccid paralysis** involves complete **loss of muscle tone and voluntary movement**, characteristic of **lower motor neuron lesions**, **spinal cord injury**, or certain **neuromuscular diseases**. - Cerebral palsy is an **upper motor neuron disorder** typically presenting with **spasticity, dyskinesia, or ataxia**, rather than pure flaccid paralysis.
Question 7: Best therapy suited to teach daily life skill to a mentally challenged child:
- A. Contingency management (Correct Answer)
- B. Cognitive reconstruction
- C. Self instruction
- D. CBT (Cognitive behavior therapy)
Explanation: ***Contingency management*** - This therapy involves consistently **rewarding desired behaviors** and withholding rewards for undesirable ones, which is highly effective for teaching new skills to individuals with intellectual disabilities. - It uses principles of **operant conditioning** to shape behavior through positive reinforcement, making it suitable for acquiring daily living skills. *Cognitive reconstruction* - This technique focuses on identifying and changing **maladaptive thought patterns**, which typically requires a higher level of cognitive function. - It is generally not the primary or most effective approach for teaching concrete daily life skills to individuals with significant **cognitive limitations**. *Self instruction* - This involves teaching individuals to guide their own behavior using **internal verbal cues** or self-talk. - While beneficial for some, it often requires a certain degree of **abstract thinking** and memory, making it less suitable as a standalone method for those with profound cognitive challenges in acquiring basic skills. *CBT (Cognitive behavior therapy)* - CBT integrates cognitive and behavioral strategies to address emotional and behavioral problems by modifying **thoughts, feelings, and behaviors**. - While beneficial for a range of psychological issues, its emphasis on **cognitive restructuring** makes it less directly applicable or the most effective first-line therapy for teaching concrete, functional daily living skills to mentally challenged children.
Question 8: Combination of appearance in CTEV
- A. Equinus, eversion, forefoot adduction, cavus
- B. Equinus, inversion, forefoot adduction, planus
- C. Equinus, inversion, forefoot adduction, cavus (Correct Answer)
- D. Equinus, eversion, forefoot abduction, cavus
Explanation: ***Equinus, inversion, forefoot adduction, cavus*** - The classic presentation of **clubfoot** (CTEV) involves a characteristic combination of deformities: **equinus** (fixed plantarflexion of the ankle), **inversion** (tilting of the heel inward), **forefoot adduction** (inward turning of the front of the foot), and **cavus** (an abnormally high arch). - These four components are essential for the diagnosis and classification of CTEV. *Equinus, eversion, forefoot adduction, cavus* - This option incorrectly lists **eversion** instead of inversion. Eversion involves the outward tilting of the heel and is not a feature of CTEV. - While equinus, forefoot adduction, and cavus are typical, the presence of eversion rules out classic CTEV. *Equinus, inversion, forefoot adduction, planus* - This option incorrectly lists **planus** (pes planus or flatfoot) instead of cavus. Cavus (high arch) is a defining characteristic of CTEV, not a flatfoot. - While equinus, inversion, and forefoot adduction are correct, the presence of planus makes this option incorrect. *Equinus, eversion, forefoot abduction, cavus* - This option incorrectly lists both **eversion** and **forefoot abduction**. Eversion is the outward tilting of the heel, and forefoot abduction is the outward turning of the front of the foot. - Both eversion and forefoot abduction are opposite to the deformities seen in classical CTEV.
Question 9: A patient presents with a 5th metatarsal fracture. How many days would he/she need to wear a cast?
- A. 6-8 weeks (Correct Answer)
- B. 2-3 weeks
- C. 16-20 weeks
- D. 3-5 weeks
Explanation: ***6-8 weeks*** - For most **5th metatarsal fractures**, especially **Jones fractures** or more significant avulsion fractures, **non-weight-bearing** immobilization in a cast, boot, or splint is typically required for **6 to 8 weeks** to allow for proper bone healing. - The **poor vascular supply** to the metaphyseal-diaphyseal junction of the 5th metatarsal (in Jones fractures) often necessitates a longer immobilization period. *2-3 weeks* - This duration is generally too short for the adequate healing of most 5th metatarsal fractures, especially those that are **displaced** or involve the **watershed zone**. - A shorter period might be considered for very minor, stable **avulsion fractures** with minimal pain, but even then, a slightly longer protection might be advised. *16-20 weeks* - This length of time is typically reserved for **severe, complex fractures**, open fractures with complications, or cases requiring **multiple surgical interventions** and prolonged rehabilitation, which is not the standard for an uncomplicated 5th metatarsal fracture. - Such an extended period of immobilization could also lead to **significant muscle atrophy** and joint stiffness. *3-5 weeks* - While sometimes considered for **stable avulsion fractures** of the 5th metatarsal base or mild stress fractures, this period is often insufficient for complete healing of the more common and problematic **Jones fracture**. - Rushing the return to weight-bearing can increase the risk of **non-union** or refracture.
Question 10: Early recovery of Sudeck's atrophy can be best managed by which of the following interventions?
- A. Intraarterial injection of articaine.
- B. Intraarterial injection of novacaine. (Correct Answer)
- C. Both intraarterial injection of articaine and novacaine.
- D. Neither intraarterial injection of articaine nor novacaine.
Explanation: **Explanation:** **Sudeck’s Atrophy**, also known as Complex Regional Pain Syndrome (CRPS) Type 1, is a condition characterized by post-traumatic pain, swelling, and vasomotor instability, typically occurring after fractures (e.g., Colles' fracture). The underlying pathophysiology involves an **overactive sympathetic nervous system** leading to persistent vasospasm and localized ischemia. **Why Option B is Correct:** The management of early-stage Sudeck’s atrophy focuses on breaking the "pain-vasospasm-pain" cycle. **Intra-arterial injection of Novocaine (Procaine)** acts as a powerful vasodilator and local anesthetic. By injecting it into the main artery of the affected limb (e.g., brachial artery), it provides immediate sympathetic blockade, improves peripheral blood flow, and reduces the intense burning pain, facilitating early mobilization. **Why Other Options are Incorrect:** * **Option A:** Articaine is a local anesthetic primarily used in dentistry. While it has a rapid onset, it is not the traditional or clinically documented agent of choice for intra-arterial sympathetic blockade in CRPS management compared to Novocaine. * **Option C & D:** Since Novocaine is the specific established treatment for this intervention in classical orthopedic teaching, these options are incorrect. **Clinical Pearls for NEET-PG:** * **Radiological Hallmark:** "Spotty" or patchy osteoporosis (sudden demineralization) seen on X-ray. * **Clinical Features:** The "4 Ds" – Discoloration, Dependency edema, Degenerative changes (stiffness), and Desensitization (hyperalgesia). * **Gold Standard Diagnosis:** Triple-phase bone scan (shows increased uptake). * **Other Treatments:** Physiotherapy (most important), Vitamin C (prophylaxis), and Guanethidine blocks.
