The skill involves synthesizing data from multiple tests and measures to identify primary impairments affecting function. This may include interpreting results from range of motion, strength, and balance assessments. In this case, specific test results such as left quadriceps strength of 3/5, gait with left knee hyperextension, and Berg of 40/56 highlight left lower-extremity weakness contributing to compensatory gait pattern. Choice A is correct because it accurately reflects the integration of these findings to identify the primary impairment, showing understanding of how different tests inform a cohesive clinical picture. Choice B is incorrect because it demonstrates a common misconception, such as overemphasizing a single test result without considering the broader context. To help students: Encourage practice with sample case scenarios, emphasizing the importance of a holistic view. Teach students to look for patterns across different tests to draw accurate conclusions about impairments.

Question 3

A 40-year-old female reports lateral shoulder pain with lifting and sleep disturbance. Findings:

  • AROM: abduction 130° painful; ER 50°
  • Strength: abduction 4-/5 painful; ER 4/5
  • Functional reach: overhead reach limited by pain at end range From the provided measures, what is the most likely cause of functional limitation?
  1. Pain-limited shoulder elevation with mild rotator cuff weakness (correct answer)
  2. Normal shoulder motion and strength with no pain behavior
  3. Functional limitation is the impairment, not strength or pain
  4. Complex nerve lesion diagnosis without supporting examination findings
Explanation: This question tests NPTE physical therapy skills: integrating examination findings to characterize patient impairments. The skill involves synthesizing data from multiple tests and measures to identify primary impairments affecting function. This may include interpreting results from range of motion, strength, and balance assessments. In this case, specific test results such as AROM abduction of 130° painful, abduction strength of 4-/5 painful, and overhead reach limited by pain highlight pain-limited shoulder elevation with mild rotator cuff weakness. Choice A is correct because it accurately reflects the integration of these findings to identify the primary impairment, showing understanding of how different tests inform a cohesive clinical picture. Choice B is incorrect because it demonstrates a common misconception, such as overemphasizing a single test result without considering the broader context. To help students: Encourage practice with sample case scenarios, emphasizing the importance of a holistic view. Teach students to look for patterns across different tests to draw accurate conclusions about impairments.

Question 4

A 65-year-old male post-stroke is evaluated for household ambulation. Findings:

  • Gait: left toe drag, reduced knee flexion in swing, uses cane
  • Strength (left): ankle DF 2/5, knee flex 3-/5
  • Balance: Berg 45/56; mild deficits with reaching forward Which test finding most strongly suggests a need for intervention?
  1. Left ankle dorsiflexion strength of 2/5 with toe drag (correct answer)
  2. Berg score of 45/56 indicates no balance needs
  3. Use of cane alone proves severe balance impairment
  4. Opposite finding: strong dorsiflexors causing excessive foot clearance
Explanation: This question tests NPTE physical therapy skills: integrating examination findings to characterize patient impairments. The skill involves synthesizing data from multiple tests and measures to identify primary impairments affecting function. This may include interpreting results from range of motion, strength, and balance assessments. In this case, specific test results such as left ankle dorsiflexion strength of 2/5, gait with toe drag and cane use, and Berg of 45/56 highlight left ankle dorsiflexion strength of 2/5 with toe drag. Choice A is correct because it accurately reflects the integration of these findings to identify the primary impairment, showing understanding of how different tests inform a cohesive clinical picture. Choice B is incorrect because it demonstrates a common misconception, such as overemphasizing a single test result without considering the broader context. To help students: Encourage practice with sample case scenarios, emphasizing the importance of a holistic view. Teach students to look for patterns across different tests to draw accurate conclusions about impairments.

Question 5

A 55-year-old female presents with a 6-month history of progressive pain and stiffness in both shoulders. She reports significant difficulty with overhead activities and fastening her bra. Examination reveals that both shoulders have a capsular pattern of restriction: active and passive external rotation are more limited than abduction, which is more limited than internal rotation. Glenohumeral passive external rotation is 10 degrees on the right and 15 degrees on the left. The patient's subjective report includes pervasive fatigue, recent unexplained weight gain, and a constant feeling of being cold.

Given the bilateral, symmetrical nature of the shoulder impairment combined with the reported systemic symptoms, the physical therapist should be MOST suspicious of an underlying pathology related to which system?

  1. Rheumatologic, such as polymyalgia rheumatica.
  2. Cardiovascular, such as referred cardiac pain.
  3. Neurologic, such as bilateral axillary nerve palsy.
  4. Endocrine, such as hypothyroidism. (correct answer)
Explanation: When you encounter bilateral shoulder restrictions with systemic symptoms on the NPTE, think beyond just musculoskeletal causes and consider how other body systems can manifest as joint dysfunction. The correct answer is D because hypothyroidism creates a classic presentation combining bilateral adhesive capsulitis with characteristic systemic symptoms. Thyroid hormone deficiency leads to increased collagen cross-linking and glycosaminoglycan deposits in joint capsules, causing the bilateral capsular patterns described. The systemic symptoms—fatigue, unexplained weight gain, and cold intolerance—are hallmark signs of hypothyroidism. This endocrine disorder is notorious for causing bilateral frozen shoulders, particularly in middle-aged women. Option A (polymyalgia rheumatica) would typically present with more proximal muscle pain and stiffness, especially in the neck, shoulders, and hips, rather than the specific capsular restriction pattern described. Option B (cardiovascular/referred cardiac pain) doesn't explain the bilateral capsular restrictions or the constellation of systemic symptoms like weight gain and cold intolerance. Option C (bilateral axillary nerve palsy) would cause weakness and sensory loss over the deltoid region rather than capsular restriction patterns, and wouldn't account for the systemic symptoms. Remember this pattern for the NPTE: bilateral joint restrictions combined with systemic symptoms should trigger consideration of endocrine disorders, especially hypothyroidism. The combination of frozen shoulders with fatigue, weight gain, and cold intolerance is a red flag requiring medical referral before aggressive physical therapy intervention.

Question 6

A 65-year-old male post-stroke reports near-falls when turning quickly. Findings:

  • Gait: wide base, decreased left stance stability, slow turns
  • Strength (left): hip abductors 2+/5, ankle DF 3/5
  • Balance: Berg 36/56; needs assistance with tandem stance Considering balance assessment results, what functional limitation is most evident?
  1. Difficulty with turning and narrow-base tasks during walking (correct answer)
  2. Inability to speak clearly is the primary balance limitation
  3. Normal balance because dorsiflexion is 3/5
  4. Impairment is inability to ambulate independently as a body deficit
Explanation: This question tests NPTE physical therapy skills: integrating examination findings to characterize patient impairments. The skill involves synthesizing data from multiple tests and measures to identify primary impairments affecting function. This may include interpreting results from range of motion, strength, and balance assessments. In this case, specific test results such as Berg of 36/56 with assistance needed for tandem stance, gait with wide base and slow turns, and left hip abductor strength of 2+/5 highlight difficulty with turning and narrow-base tasks during walking. Choice A is correct because it accurately reflects the integration of these findings to identify the primary impairment, showing understanding of how different tests inform a cohesive clinical picture. Choice C is incorrect because it demonstrates a common misconception, such as overemphasizing a single test result without considering the broader context. To help students: Encourage practice with sample case scenarios, emphasizing the importance of a holistic view. Teach students to look for patterns across different tests to draw accurate conclusions about impairments.

Question 7

A 65-year-old male is 6 weeks post-stroke with left-sided weakness and slower walking. Findings:

  • Gait: decreased left stance time, left foot clearance reduced, circumduction
  • Strength (left): hip flex 3/5, knee ext 3+/5, ankle DF 2/5
  • Balance: Berg 38/56; needs supervision with turns Based on results, which impairment is most likely present?
  1. Primary impairment is impaired left dorsiflexion strength affecting swing (correct answer)
  2. Primary impairment is normal gait with isolated shoulder weakness
  3. Primary impairment is fear of falling as a strength deficit
  4. Primary impairment is increased left ankle strength causing toe drag
Explanation: This question tests NPTE physical therapy skills: integrating examination findings to characterize patient impairments. The skill involves synthesizing data from multiple tests and measures to identify primary impairments affecting function. This may include interpreting results from range of motion, strength, and balance assessments. In this case, specific test results such as left ankle dorsiflexion strength of 2/5, gait with reduced foot clearance and circumduction, and Berg of 38/56 highlight impaired left dorsiflexion strength affecting swing. Choice A is correct because it accurately reflects the integration of these findings to identify the primary impairment, showing understanding of how different tests inform a cohesive clinical picture. Choice B is incorrect because it demonstrates a common misconception, such as overemphasizing a single test result without considering the broader context. To help students: Encourage practice with sample case scenarios, emphasizing the importance of a holistic view. Teach students to look for patterns across different tests to draw accurate conclusions about impairments.

Question 8

A 66-year-old male, on day 3 post-total knee arthroplasty, experiences a sudden onset of severe shortness of breath and sharp right-sided chest pain that worsens with deep inspiration. His vital signs are: heart rate 120 bpm, respiratory rate 28 breaths/min, blood pressure 130/85 mmHg, and SpO2 89% on room air. Lung auscultation is clear bilaterally with no wheezes or crackles. The patient's Wells score for pulmonary embolism is calculated to be 6.

The integration of the patient's acute presentation, risk factors, vital signs, and auscultation findings is MOST suspicious for which of the following conditions?

  1. Postoperative atelectasis.
  2. Acute exacerbation of congestive heart failure.
  3. Hospital-acquired pneumonia.
  4. Pulmonary embolism. (correct answer)
Explanation: When evaluating acute respiratory distress in post-surgical patients, you must systematically integrate clinical presentation, risk factors, and objective findings to differentiate between common postoperative complications. This patient's constellation of findings strongly points to pulmonary embolism (PE). The key indicators include: major orthopedic surgery (total knee arthroplasty) creating high thrombotic risk, sudden onset of dyspnea with pleuritic chest pain, tachycardia (120 bpm), tachypnea (28 breaths/min), hypoxemia (SpO2 89%), and most importantly, clear lung sounds despite severe respiratory distress. The Wells score of 6 indicates high probability for PE, as scores ≥4 suggest significant risk. Option A, postoperative atelectasis, typically presents more gradually with diminished breath sounds and doesn't explain the severe hypoxemia or pleuritic pain pattern. Option B, acute CHF exacerbation, would present with bilateral crackles, possibly wheezes, and wouldn't typically cause sharp, inspiration-worsening chest pain. The clear lung sounds effectively rule this out. Option C, hospital-acquired pneumonia, would present with abnormal lung sounds (crackles, rhonchi), fever, and productive cough - none of which are present here. The discordance between severe respiratory symptoms and normal lung auscultation is a classic PE presentation that distinguishes it from other pulmonary conditions. Study tip: Remember the triad for post-surgical PE suspicion: high-risk procedure + sudden cardiopulmonary symptoms + clear lungs despite hypoxemia. Clear lung sounds with severe dyspnea should immediately raise PE concerns in surgical patients.

Question 9

A 45-year-old competitive swimmer presents with a 3-month history of worsening right anterior shoulder pain. The examination reveals a painful arc between 80-110 degrees of active abduction. The Neer's and Hawkins-Kennedy tests are positive for sharp, anterior pain. The Speed's test is positive. The active compression (O'Brien's) test elicits a deep, painful "clunk" with the forearm pronated, which is eliminated with the forearm supinated. The apprehension and relocation tests for anterior instability are negative.

Based on the integration of these findings, which of the following BEST characterizes the patient's primary impairment?

  1. Subacromial impingement syndrome with isolated rotator cuff tendinosis.
  2. Anterior glenohumeral instability leading to secondary impingement.
  3. Superior labral anterior-posterior (SLAP) lesion with associated bicipital involvement. (correct answer)
  4. Calcific tendinitis of the supraspinatus tendon causing a mechanical block.
Explanation: The correct answer is C. This conclusion requires integrating multiple findings. While the painful arc, Neer's, and Hawkins-Kennedy tests suggest impingement, the positive Speed's test indicates biceps tendon involvement, and the painful "clunk" with the O'Brien's test is highly specific for a SLAP lesion. The SLAP lesion is the likely primary pathology, causing secondary biceps irritation and impingement symptoms. A is incorrect because it ignores the specific labral test findings. B is incorrect because tests for anterior instability were explicitly negative. D is incorrect as calcific tendinitis would likely present with more severe, constant pain and significant ROM limitations, and is not specifically indicated by these tests.

Question 10

A 38-year-old long-distance runner reports a 4-month history of deep right buttock pain that sometimes radiates to the posterior thigh. A neurological screen of the lower extremities is unremarkable. The straight leg raise (SLR) test is positive for deep gluteal and posterior thigh pain at 60 degrees of hip flexion. The Slump test is negative. The FAIR test (flexion, adduction, internal rotation) reproduces the deep buttock pain. Passive hip internal rotation is 10 degrees and painful, while the contralateral side has 35 degrees of pain-free motion.

Integrating these findings, what is the MOST likely primary source of the patient's symptoms?

  1. Lumbar disc herniation with S1 nerve root impingement.
  2. Piriformis syndrome causing sciatic nerve compression.
  3. Intra-articular hip pathology with secondary nerve irritation. (correct answer)
  4. High hamstring tendinopathy at the ischial tuberosity.
Explanation: The correct answer is C. While positive SLR and FAIR tests can suggest sciatica or piriformis syndrome, the critical finding to integrate is the marked, painful limitation in passive hip internal rotation. This is a classic sign of intra-articular hip pathology, such as femoroacetabular impingement (FAI) or a labral tear, which can refer pain to the buttock and mimic sciatica. A is unlikely due to the negative Slump test and normal neurological screen. B is less likely to be the primary driver given the significant intra-articular hip sign. D would typically present with pain on palpation of the ischial tuberosity and with resisted hamstring contraction, and would not cause a bony block to hip rotation.

Question 11

A 58-year-old male presents with right leg weakness. Examination reveals 3/5 strength in ankle dorsiflexion and great toe extension. Sensation is decreased over the dorsum of the foot. The patellar tendon reflex is 3+, and the Achilles tendon reflex is 2+. Ankle clonus is absent. The Babinski sign is present on the right.

Which characterization of the patient's condition BEST integrates these neurological findings?

  1. A pure lower motor neuron lesion, such as an L5 radiculopathy.
  2. An upper motor neuron lesion, such as a stroke in the left motor cortex.
  3. A spinal cord lesion causing both upper and lower motor neuron signs. (correct answer)
  4. A peripheral neuropathy affecting the common fibular nerve.
Explanation: The correct answer is C. The key is to integrate the mixed upper motor neuron (UMN) and lower motor neuron (LMN) signs. The focal weakness in an L5 myotome and diminished sensation in an L5 dermatome are LMN signs. However, the hyperreflexic patellar reflex (3+) and the positive Babinski sign are classic UMN signs. A pure LMN lesion (A and D) would present with hyporeflexia. A pure UMN lesion (B) would cause weakness in a different pattern (e.g., extensors of the leg) and would not explain the dermatomal sensory loss. Only a spinal cord lesion can simultaneously affect the nerve root or anterior horn cells at one level (LMN signs) and the descending corticospinal tracts to levels below (UMN signs).

Question 12

A 68-year-old male with a history of chronic obstructive pulmonary disease (COPD) presents with a 1-week history of increased dyspnea on exertion. On auscultation, there are faint expiratory wheezes and bibasilar crackles. An S3 heart sound is noted on cardiac auscultation. The patient exhibits 2+ pitting edema in both ankles. His FEV1/FVC ratio from a recent pulmonary function test is 0.60.

Integrating these clinical findings, the patient's presentation is MOST indicative of which of the following?

  1. An acute exacerbation of COPD without other complications.
  2. Decompensated congestive heart failure with pulmonary edema. (correct answer)
  3. Bilateral pneumonia in the lower lobes of the lungs.
  4. Atelectasis secondary to mucus plugging from chronic bronchitis.
Explanation: The correct answer is B. The patient has signs of both pulmonary and cardiac disease. While the wheezing and low FEV1/FVC ratio are consistent with his COPD history (A), the presence of bibasilar crackles, an S3 heart sound, and bilateral pitting edema are classic signs of left-sided congestive heart failure. The integration of these cardiac signs with the worsening dyspnea points to decompensated CHF as the primary cause of his acute decline. Pneumonia (C) would typically present with fever and focal consolidation signs. Atelectasis (D) would present with diminished breath sounds over the affected area, not necessarily crackles and signs of fluid overload.

Question 13

A 40-year-old male presents with left neck and arm pain. Symptoms are reproduced with cervical extension and left side-bending (positive Spurling's test). The biceps reflex (C5-C6) is diminished on the left. The patient also reports that symptoms are exacerbated when carrying a heavy bag or working with his arms overhead for prolonged periods. The Adson's test is positive, reproducing paresthesias in the hand. Radial pulse is palpable throughout all tests.

Which of the following impairments BEST accounts for the complete clinical picture presented?

  1. Cervical radiculopathy at the C5-C6 level due to foraminal stenosis.
  2. Neurogenic thoracic outlet syndrome involving the brachial plexus. (correct answer)
  3. Acute cervical strain with referred pain to the upper extremity.
  4. Carpal tunnel syndrome with proximal radiation of symptoms.
Explanation: The correct answer is B. This case requires differentiation between cervical radiculopathy and thoracic outlet syndrome (TOS). While the positive Spurling's test and diminished reflex point towards radiculopathy (A), the reproduction of symptoms with overhead activities and a positive Adson's test are classic findings for TOS. The fact that both sets of provocative tests are positive suggests that the brachial plexus is being compressed as it passes through the thoracic outlet, which can mimic radicular signs. The positional nature of the symptoms (carrying a bag, arms overhead) is a key feature of TOS. C and D do not adequately explain the combination of positive cervical and thoracic outlet special tests.

Question 14

A 48-year-old patient reports a 6-month history of right heel pain. The pain is most severe with the first few steps in the morning. There is tenderness to palpation at the medial calcaneal tubercle. However, the patient also reports intermittent burning pain and numbness along the medial aspect of the ankle and into the sole of the foot, especially after prolonged standing. The Tinel's sign is positive when percussing posterior to the medial malleolus. Dorsiflexion-eversion test is also positive.

Integrating these findings, which of the following provides the MOST complete characterization of the patient's condition?

  1. Plantar fasciitis with an associated calcaneal spur.
  2. Tarsal tunnel syndrome coexisting with or mimicking plantar fasciitis. (correct answer)
  3. S1 radiculopathy causing referred pain to the plantar aspect of the foot.
  4. Fat pad atrophy leading to localized heel pain under the calcaneus.
Explanation: The correct answer is B. The patient presents with classic signs of plantar fasciitis (first-step pain, medial calcaneal tubercle tenderness). However, the integration of neurological symptoms (burning, numbness) and positive neural provocation tests (Tinel's sign, dorsiflexion-eversion test) points strongly to involvement of the posterior tibial nerve, characteristic of tarsal tunnel syndrome. The clinical picture is best described as a combination of the two or tarsal tunnel syndrome presenting with heel pain. A and D fail to account for the neurological findings. C is less likely as there are no reported back or proximal leg symptoms, and the nerve signs are localized to the tarsal tunnel.

Question 15

A 72-year-old female presents with a wound on her left medial lower leg, just superior to the malleolus. The wound has an irregular shape, a shallow base with fibrinous slough, and significant surrounding edema. The periwound skin exhibits hemosiderin staining. The patient's ankle-brachial index (ABI) is 0.85. The dorsalis pedis and posterior tibial pulses are present but faint (1+). The leg is not painful when elevated.

Based on the integration of these findings, the wound should be classified as which of the following types?

  1. A pure venous insufficiency ulcer.
  2. A pure arterial insufficiency ulcer.
  3. A mixed-etiology (arterial and venous) ulcer. (correct answer)
  4. A neuropathic (diabetic) ulcer.
Explanation: The correct answer is C. The key is to synthesize the competing signs of venous and arterial disease. The location (medial malleolus), irregular shape, significant edema, and hemosiderin staining are classic signs of a venous ulcer (A). However, the ABI of 0.85 indicates mild peripheral arterial disease, and the faint pulses confirm compromised arterial inflow. Pure arterial ulcers (B) typically occur on the toes or lateral malleolus, have a "punched-out" appearance, and are very painful, especially with elevation. Neuropathic ulcers (D) occur on pressure points on the plantar surface of the foot and are associated with sensory loss. The presence of both strong venous and mild arterial signs characterizes this as a mixed-etiology ulcer.

Question 16

A 14-year-old basketball player complains of anterior knee pain. The pain is worse with running, jumping, and prolonged sitting. Examination reveals a positive patellar compression (Clarke's) test. There is also marked tenderness to palpation of the soft tissue just distal to the inferior pole of the patella. The patient reports sharp pain with forced, active terminal knee extension and has a visibly high-riding patella (patella alta). Squatting reproduces the anterior knee pain.

Synthesizing these examination findings, which of the following is the MOST likely diagnosis?

  1. Patellofemoral pain syndrome secondary to chondromalacia patellae.
  2. Osgood-Schlatter disease at the tibial tuberosity.
  3. Infrapatellar fat pad (Hoffa's) syndrome. (correct answer)
  4. Patellar tendinopathy (Jumper's Knee).
Explanation: The correct answer is C. While some signs like pain with squatting and a positive Clarke's test are common in general patellofemoral pain (A), the integration of three specific findings points to infrapatellar fat pad syndrome: 1) exquisite tenderness specifically in the soft tissue inferior to the patella, 2) pain with forced terminal knee extension (which compresses the fat pad), and 3) the predisposing factor of patella alta. Osgood-Schlatter disease (B) involves tenderness over the tibial tuberosity, not the inferior patellar pole. Patellar tendinopathy (D) involves tenderness within the tendon itself, and pain is typically worse with energy storage activities (like the loading phase of a jump) rather than terminal extension.

Question 17

A 65-year-old male is evaluated for a 2-month history of constant, deep low back pain. The pain is rated 6/10 and is not significantly altered by changes in position or activity level. It often wakes him from sleep. A neurological screen is negative, and tests for nerve root tension are negative. The patient's past medical history is significant for smoking 2 packs of cigarettes per day for 40 years. He also reports a 15-pound unintentional weight loss over the past 3 months.

The integration of the patient's symptom report and history MOST strongly suggests that the pain is originating from which source?

  1. A viscerogenic or systemic disease process. (correct answer)
  2. Degenerative changes, such as lumbar spinal stenosis.
  3. Mechanical derangement, such as a lumbar disc herniation.
  4. Psychosocial factors, consistent with central sensitization.
Explanation: When you encounter questions about low back pain on the NPTE, you need to systematically differentiate between mechanical, neurological, and systemic causes based on the symptom pattern and patient history. This patient presents several classic red flags for systemic disease. The pain is constant and unrelenting, unaffected by position or activity changes - a hallmark of viscerogenic pain that differs dramatically from mechanical back pain. Night pain that disrupts sleep is particularly concerning for malignancy or other systemic processes. His significant smoking history (80 pack-years) creates high risk for lung cancer with potential spinal metastases. The unexplained 15-pound weight loss over three months is another major red flag for cancer or other systemic disease. Option A is correct because the combination of constant pain, night symptoms, smoking history, and weight loss strongly suggests a viscerogenic or systemic source requiring immediate medical referral. Option B (spinal stenosis) typically causes neurogenic claudication with walking tolerance limitations and position-dependent symptoms - neither present here. Option C (disc herniation) would likely show positive nerve root tension tests and position-related pain variations, both absent in this case. The neurological screen being negative also argues against mechanical nerve compression. Option D (central sensitization) doesn't explain the acute onset, night pain pattern, or concerning medical history. Remember: Constant, non-mechanical pain combined with constitutional symptoms (weight loss) and significant risk factors (heavy smoking) should immediately trigger suspicion for systemic disease. These patients need urgent medical evaluation, not physical therapy intervention.

Question 18

A 52-year-old female is evaluated 8 weeks after a non-displaced distal radius fracture, which was managed with casting. She complains of severe, burning pain in the entire hand, rated 9/10, that is disproportionate to the original injury. The examination reveals significant non-pitting edema of the hand and fingers. The skin is mottled, cyanotic, and cooler to the touch compared to the contralateral hand. The patient demonstrates extreme pain and guarding with any attempted active or passive range of motion of the wrist and fingers (allodynia).

This constellation of signs and symptoms is the hallmark presentation of which of the following conditions?

  1. Delayed union of the distal radius fracture.
  2. Severe disuse atrophy and joint contracture.
  3. Median nerve compression at the carpal tunnel.
  4. Complex Regional Pain Syndrome (CRPS). (correct answer)
Explanation: When evaluating post-fracture complications, you need to recognize the distinct clinical patterns that differentiate various conditions. The key here is identifying when symptoms are disproportionate to the original injury and involve multiple body systems. This patient's presentation is classic for Complex Regional Pain Syndrome (CRPS), making D correct. CRPS is characterized by severe, burning pain that's disproportionate to the inciting event, along with a triad of symptoms: autonomic dysfunction (mottled, cyanotic, cool skin), vascular changes (non-pitting edema), and motor/sensory abnormalities (allodynia - pain from normally non-painful stimuli). The 8-week timeline after fracture is also typical, as CRPS often develops weeks to months after the initial trauma. Option A (delayed union) would present with continued pain at the fracture site, possibly with deformity or instability, but wouldn't cause the systemic skin changes, temperature differences, or allodynia seen here. Option B (disuse atrophy) might cause stiffness and weakness, but the severe burning pain, skin discoloration, and temperature changes aren't consistent with simple disuse. Option C (carpal tunnel syndrome) could cause pain and numbness, but it would be limited to the median nerve distribution (thumb, index, middle fingers) and wouldn't explain the whole-hand edema, skin color changes, or temperature differences. For the NPTE, remember that CRPS questions often emphasize the "disproportionate pain" phrase and the constellation of autonomic, vascular, and sensory changes affecting the entire limb beyond the original injury site.

Question 19

A 62-year-old male presents with a 9-month history of progressive weakness in his hands and difficulty walking. Examination reveals marked atrophy and visible fasciculations in the first dorsal interosseous and thenar muscles bilaterally. Grip strength is 3/5. In the lower extremities, patellar and Achilles reflexes are 3+, and sustained clonus is present at both ankles. The patient also has a positive Hoffman's sign bilaterally. Examination of the cranial nerves reveals fasciculations of the tongue.

The combination of these widespread upper and lower motor neuron signs, including bulbar involvement, is MOST characteristic of which condition?

  1. Cervical myelopathy secondary to spondylosis.
  2. Multifocal motor neuropathy (MMN).
  3. Spinal muscular atrophy (SMA).
  4. Amyotrophic Lateral Sclerosis (ALS). (correct answer)
Explanation: When you encounter a case with both upper and lower motor neuron signs, you're dealing with a complex neurological presentation that requires careful analysis of the symptom pattern. This patient shows classic mixed motor neuron pathology: lower motor neuron signs (muscle atrophy, fasciculations in hands and tongue, weakness) combined with upper motor neuron signs (hyperreflexia, clonus, positive Hoffman's sign). The key diagnostic clue is the bulbar involvement evidenced by tongue fasciculations, which indicates cranial nerve motor nuclei are affected. Answer D (ALS) is correct because it's the only condition that produces this exact triad: upper motor neuron degeneration, lower motor neuron degeneration, and bulbar involvement. ALS characteristically affects motor neurons in the brain, brainstem, and spinal cord simultaneously, explaining the widespread mixed findings. Answer A (cervical myelopathy) would primarily cause upper motor neuron signs below the lesion level, but wouldn't explain the lower motor neuron findings or bulbar symptoms. Answer B (multifocal motor neuropathy) affects only lower motor neurons and typically spares reflexes and upper motor neuron function. Answer C (spinal muscular atrophy) involves only lower motor neuron degeneration without the hyperreflexia or upper motor neuron signs seen here. Remember this pattern: when you see mixed upper and lower motor neuron signs with bulbar involvement (especially tongue fasciculations), think ALS first. The combination of weakness with both atrophy/fasciculations AND hyperreflexia is pathognomonic for motor neuron disease.

Question 20

A 70-year-old female is evaluated for dizziness, which she describes as a spinning sensation (vertigo) lasting for 20-30 seconds, triggered specifically by rolling over to the right in bed and looking up. She denies hearing loss, tinnitus, or other neurological symptoms. The therapist performs a right Dix-Hallpike test, which reproduces her vertigo and elicits upbeating torsional nystagmus. A neurological screen, including tests for coordination and central vestibular signs, is negative.

Which of the following characterizations BEST integrates the patient's symptom description and objective test results?

  1. Right posterior canal benign paroxysmal positional vertigo (BPPV). (correct answer)
  2. Meniere's disease affecting the right ear.
  3. Vertebrobasilar insufficiency triggered by head movements.
  4. Right-sided vestibular neuritis.
Explanation: The correct answer is A. This is a classic presentation where all findings converge on a single diagnosis. The symptom description (brief, spinning vertigo triggered by specific position changes) is highly suggestive of BPPV. The reproduction of symptoms and the observation of upbeating torsional nystagmus during the right Dix-Hallpike test are pathognomonic for posterior canal BPPV on the right side. Meniere's disease (B) involves longer episodes of vertigo accompanied by hearing loss and tinnitus. Vertebrobasilar insufficiency (C) might be triggered by neck extension but would likely cause other central signs (e.g., diplopia, dysarthria) and the nystagmus pattern would be different (e.g., pure vertical). Vestibular neuritis (D) presents with acute, severe vertigo lasting for days, not brief, positionally-triggered episodes.
