Principles of Rehabilitation Indian Medical PG Practice Questions and MCQs
Question 1: Which of the following phases are directly involved in the recovery phase of the disaster cycle?
- A. Response and Rehabilitation
- B. Mitigation and Rehabilitation
- C. Response and Preparedness
- D. Rehabilitation and Reconstruction (Correct Answer)
Explanation: ***Rehabilitation and Reconstruction*** - **Rehabilitation** is the short-term recovery phase focusing on restoring essential services, providing temporary shelter, medical care, and supporting affected populations to resume normal activities. - **Reconstruction** is the long-term recovery phase involving rebuilding damaged infrastructure, permanent housing, economic restoration, and development improvements. - These two phases together constitute the **recovery phase** of the disaster cycle according to standard disaster management frameworks (WHO, NDMA). *Mitigation and Rehabilitation* - While **rehabilitation** is correctly part of recovery, **mitigation** is traditionally considered a separate continuous phase or part of preparedness, focused on reducing future disaster risks. - **Mitigation** measures are implemented throughout the disaster cycle, not specifically as a direct component of the recovery phase. *Response and Rehabilitation* - **Response** refers to immediate life-saving actions during and immediately after a disaster (search and rescue, emergency medical care, evacuation). - **Response** precedes the recovery phase and is distinct from it, though **rehabilitation** is indeed part of recovery. *Response and Preparedness* - **Preparedness** involves planning, training, and resource allocation before a disaster occurs. - **Response** is the immediate action during/after the disaster. - Neither constitutes the recovery phase, which follows after the immediate response is complete.
Question 2: You are working in a primary health center (PHC) situated in a high seismic zone. Which of the following actions should you take as part of preparedness for an emergency?
- A. Ensure all financial and other resources are available for disaster preparedness.
- B. Increase public awareness through campaigns and loudspeakers.
- C. Follow instructions given over the phone or radio by higher officials.
- D. Conduct a simulation for the disaster and assess the response. (Correct Answer)
Explanation: ***Conduct a simulation for the disaster and assess the response.*** - **Simulation exercises** are crucial for testing the effectiveness of a disaster preparedness plan and identifying weaknesses in the response system. - This allows for refinement of protocols, training of personnel, and ensuring that all team members understand their roles during an actual emergency. *Ensure all financial and other resources are available for disaster preparedness.* - While important for effective disaster management, simply "ensuring" resources are available is not an action of preparedness, but rather an **enabling condition**. - This statement focuses on the availability of resources rather than a proactive step to prepare the PHC for an emergency. *Increase public awareness through campaigns and loudspeakers.* - **Public awareness campaigns** are vital for community preparedness, but this action is primarily for the general population and not a specific preparedness action for the PHC itself in terms of its operational readiness. - While a PHC might be involved in public awareness, its core preparedness involves internal actions to ensure its functionality during a disaster. *Follow instructions given over the phone or radio by higher officials.* - This describes a reaction during or immediately before a disaster, rather than a proactive **preparedness measure**. - Relying solely on real-time instructions from higher officials during an emergency without prior planning can lead to delays and inefficiencies.
Question 3: During reconstruction of an amputated limb which of the following is done first?
- A. Arterial repair
- B. Venous repair
- C. Fixation of the bone (Correct Answer)
- D. Nerve anastomoses
Explanation: ***Fixation of the bone*** - **Bone stabilization** is the crucial first step to create a rigid framework, allowing for subsequent precise vascular and nerve repairs. - This prevents movement and tension on delicate repairs, which could lead to failure of the reconnected vessels and nerves. *Arterial repair* - While critical for blood supply, arterial repair is performed *after* bone fixation to ensure the vessels are not disrupted by later bone manipulation. - It's typically done before venous repair to establish arterial flow and identify any potential venous back pressure that needs addressing. *Venous repair* - Venous repair is usually performed after arterial repair, as establishing arterial inflow can help distend the veins, making them easier to identify and repair. - Repairing veins first without establishing arterial flow immediately is less effective and may lead to congestion once arterial flow is restored. *Nerve anastomoses* - Nerve repair is typically the last major step in an amputation reconstruction, following bone stabilization and full vascular repair. - Nerves are fragile and require a stable, well-perfused environment to optimize the chances of successful regeneration.
Question 4: A patient prescribed crutches for residual paralysis in poliomyelitis is a type of -
- A. Disability limitation
- B. Primordial prevention
- C. Primary prevention
- D. Rehabilitation (Correct Answer)
Explanation: ***Rehabilitation*** - Rehabilitation is a component of **tertiary prevention** that aims to restore maximum functional ability after permanent damage has occurred from disease. - Providing crutches to a polio patient with **residual (established) paralysis** helps restore mobility and independence, allowing the patient to adapt to their permanent disability. - This intervention occurs **after the disease has run its course** and permanent sequelae have developed, which is the hallmark of rehabilitation. *Disability limitation* - Disability limitation is another component of **tertiary prevention** but focuses on **preventing progression or complications** of an already established disease. - It applies during the **disease active phase** to minimize further damage (e.g., physiotherapy during acute polio to prevent contractures, or strict glycemic control in diabetes to prevent complications). - In this case, the paralysis is **residual (fixed)**, not active, so we are beyond the disability limitation phase. *Primordial prevention* - Primordial prevention targets the underlying environmental and social determinants to prevent the emergence of risk factors at the population level. - This occurs **before any risk factors** for disease have developed (e.g., policies to prevent emergence of sedentary lifestyles). - Not applicable to a patient with established disease. *Primary prevention* - Primary prevention aims to prevent disease occurrence by reducing risk factors or increasing resistance (e.g., polio vaccination, health education). - This intervention is applied **before the disease occurs**, which is not the case for a patient with established paralysis from poliomyelitis.
Question 5: The recommended non-surgical treatment of stress incontinence is:
- A. Electrical stimulation
- B. Bladder training
- C. Pelvic floor muscle exercises (Correct Answer)
- D. Vaginal cone/weights
Explanation: ***Pelvic floor muscle exercises*** - **Pelvic floor muscle exercises** (Kegel exercises) are considered the **first-line non-surgical treatment** for stress urinary incontinence. - They aim to strengthen the **pelvic floor muscles**, which support the urethra and bladder, improving urethral closure pressure. *Electrical stimulation* - **Electrical stimulation** is a passive treatment method that involves using a probe to deliver electrical currents to the pelvic floor muscles. - It is typically used as a **secondary treatment** when active pelvic floor muscle training is difficult or ineffective, as it does not actively engage the patient in muscle control. *Bladder training* - **Bladder training** is a behavioral therapy primarily used for **urge incontinence** or mixed incontinence, not specifically stress incontinence. - It involves learning to suppress sudden urges to urinate and gradually increasing the time between voids to regain bladder control. *Vaginal cone/weights* - **Vaginal cones or weights** are devices inserted into the vagina that patients hold in place by contracting their pelvic floor muscles. - While they can be used to **improve pelvic floor muscle strength**, they are often considered an **adjunctive or secondary treatment**, not the primary recommended non-surgical approach.
Question 6: Healing by Haversian remodeling is a type of:
- A. Tertiary healing.
- B. Secondary healing.
- C. Primary healing. (Correct Answer)
- D. Intermediate healing.
Explanation: ***Primary healing*** - This term refers to **direct healing**, where bone fragments are in contact and movement is minimized, leading to direct bone formation without significant callus. - **Haversian remodeling**, common in rigid internal fixation, is the hallmark of primary bone healing, involving direct osteon formation across the fracture site. *Tertiary healing* - This is **not a recognized term** in the classification of bone healing processes. - Bone healing is generally categorized as primary (direct) or secondary (indirect). *Secondary healing* - This involves the formation of a **soft and then hard callus** in cases of unreduced or mobile fractures. - It is characterized by three overlapping phases: **inflammation, repair**, and **remodeling**, and does not primarily rely on Haversian remodeling. *Intermediate healing* - This is **not a formal classification** of bone healing. - Bone healing is typically dichotomized into primary and secondary healing, depending on the stability and reduction of the fracture.
Question 7: Early movement following surgery for ankylosis is
- A. Desirable (Correct Answer)
- B. Harmful
- C. Indicated only when ankylosis is one sided
- D. Unimportant
Explanation: ***Desirable*** - Early movement following surgery for **ankylosis** is crucial for preventing **re-ankylosis** and promoting the formation of a **neocartilage-like layer**. - It helps maintain joint mobility, reduce stiffness, and improves long-term functional outcomes after procedures like **arthroplasty**. *Harmful* - Delays in movement can lead to increased fibrous tissue formation, limiting the newly created joint's mobility and potentially causing **re-ankylosis**. - Prolonged immobilization after joint surgery can also lead to muscle atrophy, contractures, and impaired circulation, hindering recovery. *Indicated only when ankylosis is one sided* - The principle of early movement applies to both **unilateral** and **bilateral ankylosis** to prevent recurrence and improve range of motion in the affected joint(s). - Focusing solely on unilateral cases overlooks the functional benefits of early mobilization for all patients undergoing such surgery. *Unimportant* - Early movement is a **critical component** of postoperative recovery, as it directly impacts the success of the surgical intervention by maintaining joint space and flexibility. - Neglecting early motion can compromise the surgical outcome, increasing the risk of stiffness, pain, and the need for further interventions.
Question 8: 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.
Question 9: A patient presents with painful Myositis Ossificans around the elbow. What is the preferred treatment option in this case?
- A. Active mobilization
- B. Passive mobilization
- C. Infra-Red Therapy
- D. Immobilization (Correct Answer)
Explanation: **Explanation:** **Myositis Ossificans (MO)** is a condition characterized by heterotopic ossification (bone formation) within soft tissues, most commonly occurring after trauma or aggressive manipulation around the elbow joint. **1. Why Immobilization is the Correct Answer:** In the **acute and painful phase** of Myositis Ossificans, the primary goal is to prevent further irritation and minimize the inflammatory response that triggers bone formation. **Rest and Immobilization** (usually in a functional position) are mandatory to allow the "bone storm" to subside. Any movement during this stage can exacerbate the injury, increase bleeding, and stimulate further osteoblastic activity, worsening the condition. **2. Why the Other Options are Incorrect:** * **Passive Mobilization (B):** This is the most common cause of MO. Forceful stretching or passive manipulation of a stiff joint triggers a periosteal reaction and hematoma formation, leading to ossification. It is strictly contraindicated. * **Active Mobilization (A):** While active movement is generally safer than passive, it is still avoided in the **painful/acute stage** as it can aggravate the inflammatory process. Active exercises are only initiated once the pain subsides and the ossification has matured. * **Infra-Red Therapy (C):** Heat modalities (like IRT or Short Wave Diathermy) increase local blood flow and metabolic activity, which can potentially accelerate the ossification process in the early stages. **3. NEET-PG Clinical Pearls:** * **Common Site:** Brachialis muscle (following elbow dislocation or supracondylar fracture). * **Radiological Sign:** "Zonal phenomenon" (mature bone at the periphery, immature in the center), which distinguishes it from Osteosarcoma. * **Management Rule:** "Never massage, never stretch" a post-traumatic elbow. * **Surgery:** Only indicated after the bone has fully matured (usually 6–12 months), evidenced by a well-defined cortex on X-ray and a cold bone scan. Early surgery leads to high recurrence.
Question 10: Which of the following is NOT a deep heat therapy?
- A. Short wave diathermy
- B. Ultrasound therapy
- C. Infrared therapy (Correct Answer)
- D. Microwave therapy
Explanation: In physical medicine, heat therapy (thermotherapy) is classified based on the depth of penetration into the tissues: **Superficial** and **Deep**. ### 1. Why Infrared Therapy is the Correct Answer **Infrared therapy (IRR)** is a form of **superficial heat therapy**. It utilizes electromagnetic radiation that is absorbed primarily by the epidermis and superficial dermis. The depth of penetration is typically less than **1 cm** (usually 1–3 mm). Since it does not reach deep-seated structures like muscles, tendons, or joints, it is not classified as deep heat. Other examples of superficial heat include Paraffin Wax Bath (PWB), Hydrocollator (hot) packs, and Whirlpool baths. ### 2. Why the Other Options are Incorrect The other three options are examples of **Deep Heat Therapy (Diathermy)**, which can increase the temperature of tissues at depths of **3–5 cm** or more: * **Short Wave Diathermy (SWD):** Uses high-frequency electromagnetic currents (27.12 MHz). It heats tissues with high water content (muscles) via dipole rotation and molecular friction. * **Microwave Diathermy (MWD):** Uses higher frequency electromagnetic waves (2450 MHz). It is effective for heating tissues with high vascularity but has less penetration than SWD. * **Ultrasound Therapy (US):** Uses high-frequency **acoustic (sound) waves** rather than electromagnetic waves. It is the deepest heating modality and is excellent for localized heating of collagen-rich structures like ligaments and joint capsules. ### 3. NEET-PG High-Yield Pearls * **Deepest Heat Modality:** Ultrasound therapy (reaches up to 5 cm). * **Contraindication:** Never use diathermy (SWD/MWD) in patients with **metallic implants** or **pacemakers**, as it can cause severe internal burns or device malfunction. * **Mechanism of IRR:** Heat transfer occurs via **Radiation**. * **Mechanism of Hot Packs:** Heat transfer occurs via **Conduction**.
