Modifying InterventionsQuestion 1 of 20

A 22-year-old collegiate swimmer is receiving physical therapy for subacromial pain syndrome. The current intervention focuses on rotator cuff strengthening and scapular stabilization. The therapist adds a new exercise: resisted horizontal abduction with external rotation in a prone position. During the exercise, the patient reports a sharp pain in the anterior shoulder, distinct from their usual impingement-type ache. The therapist observes excessive anterior translation of the humeral head during the movement.

Which modification is the MOST appropriate response to the patient's report and the therapist's observation?

Decrease the resistance band tension and have the patient continue the exercise with fewer repetitions.
Instruct the patient to retract their scapula more forcefully to create more subacromial space.
Stop the prone exercise and modify it to a sidelying external rotation exercise to better control humeral head position.
Apply a hot pack to the anterior shoulder to reduce the pain before attempting the exercise again.

All questions

Question 1

A 22-year-old collegiate swimmer is receiving physical therapy for subacromial pain syndrome. The current intervention focuses on rotator cuff strengthening and scapular stabilization. The therapist adds a new exercise: resisted horizontal abduction with external rotation in a prone position. During the exercise, the patient reports a sharp pain in the anterior shoulder, distinct from their usual impingement-type ache. The therapist observes excessive anterior translation of the humeral head during the movement.

Which modification is the MOST appropriate response to the patient's report and the therapist's observation?

  1. Decrease the resistance band tension and have the patient continue the exercise with fewer repetitions.
  2. Instruct the patient to retract their scapula more forcefully to create more subacromial space.
  3. Stop the prone exercise and modify it to a sidelying external rotation exercise to better control humeral head position. (correct answer)
  4. Apply a hot pack to the anterior shoulder to reduce the pain before attempting the exercise again.
Explanation: The sharp anterior pain combined with observed anterior humeral head translation indicates that the exercise is exacerbating anterior instability or biceps tendon irritation, likely due to poor control of the humeral head. The prone position with horizontal abduction can challenge anterior stability. Continuing the exercise, even with less resistance (A), is inappropriate as it reinforces poor mechanics. Cueing scapular retraction (B) alone may not be sufficient to control the humeral head. The best modification is to change the exercise to a position that provides more stability and allows for better isolation of the rotator cuff without stressing the anterior capsule, such as sidelying external rotation. Using a modality (D) does not address the underlying biomechanical fault.

Question 2

A 35-year-old patient with multiple sclerosis is working on gait training to manage ataxia. The therapist has been using ankle weights (1 lb) to provide increased proprioceptive input, which has been moderately successful. However, as the session progresses, the patient's gait becomes significantly more erratic and they exhibit profound fatigue, needing to stop after only 5 minutes of walking.

Which intervention modification would be the MOST effective to address the observed fatigue and deteriorating gait quality?

  1. Increase the ankle weight to 2 lbs to provide a stronger stabilizing sensory input.
  2. Remove the ankle weights and focus on using a cooling vest and practicing energy conservation techniques. (correct answer)
  3. Switch from gait training to stationary cycling to reduce the cognitive load of walking.
  4. Encourage the patient to push through the fatigue, as this will improve long-term endurance.
Explanation: The patient is demonstrating Uthoff's phenomenon, a pseudoexacerbation of MS symptoms (worsening ataxia and profound fatigue) caused by an increase in core body temperature from exercise. The ankle weights, while intended to help, increase the metabolic cost of walking and contribute to faster fatigue and overheating. Encouraging them to push through (D) is contraindicated. Increasing the weight (A) would worsen the problem. The most appropriate modification is to address the core issue: heat sensitivity and energy expenditure. Removing the weights reduces the workload, and using a cooling vest directly counteracts the temperature increase. This, combined with energy conservation strategies, allows for more effective and safer practice.

Question 3

After adding 60° squats, a patient post-ACLR has knee effusion but no catching. Modify?

  1. Decrease squat depth (correct answer)
  2. Do more squat repetitions
  3. Add a long hold at bottom
  4. Continue current squats
Explanation: Effusion after adding a new exercise is a load-response signal, not a mechanical block, since there's no catching. Reduce the squats to a depth that doesn't provoke swelling, then progress gradually. Continuing the same depth is tempting because pain and catching are absent, but ignoring effusion can worsen inflammation and delay recovery.

Question 4

Repeated lumbar extension centralizes leg pain, but last reps increase pain. Modify how?

  1. Stop extension exercises
  2. Keep current 10-rep set
  3. Switch to flexion bias
  4. Do fewer extension reps (correct answer)
Explanation: Extension centralizes your leg pain, so extension is the right direction; it just needs a lower dose. Stopping extension would abandon the strategy that's helping, and switching to flexion would move symptoms the wrong way. Instead, cut the number of reps to stay below the point where pain increases, while still getting the centralizing effect.

Question 5

A patient with COPD desaturates to 84% during each 2-min walk but recovers to 94%. Modify how?

  1. Increase treadmill incline
  2. Keep same 2-min intervals
  3. Shorten walk; lengthen rest (correct answer)
  4. Discontinue treadmill walking
Explanation: Desaturation to 84% is below the 88% safety threshold, so you must reduce exercise demand. Shortening the walk and lengthening rest prevents repeated hypoxemia while still allowing training. Keeping the same 2-min intervals is tempting because recovery to 94% occurs, but it still exposes the patient to unsafe oxygen levels each bout.

Question 6

A patient with Parkinson disease freezes while turning during gait training. How modify?

  1. Increase turning speed
  2. Avoid all turns today
  3. Use rhythmic turn cues (correct answer)
  4. Add a dual-task challenge
Explanation: Parkinson-related freezing is triggered by turns and worsened by speed or divided attention. Rhythmic cues (a metronome, counting, or music) act as an external timing signal that lets you bypass the frozen motor plan and step smoothly. The tempting move is to avoid turns entirely, but that removes the task rather than modifying it.

Question 7

During treadmill training, a CHF patient reports dizziness and HR drops from 118 to 92. What action?

  1. Decrease speed and monitor
  2. Stop belt, check BP, HR (correct answer)
  3. Pause and obtain resting HR
  4. Lower incline and continue
Explanation: Dizziness with a falling heart rate during exercise in a CHF patient suggests decreased cardiac output or impending syncope, not simple fatigue. You must stop the treadmill immediately and assess blood pressure and heart rate to determine hemodynamic status. Decreasing speed or lowering incline keeps the patient at risk; pausing for a resting HR alone misses BP, which is essential to guide treatment.

Question 8

Which alternative intervention is most appropriate after acute hamstring strain worsens following aggressive stretching?

  1. Add deeper stretching and ballistic kicks to restore length rapidly
  2. Shift to relative rest, pain-limited isometrics, gradual loading, and running progression when tolerated (correct answer)
  3. Continue current stretching plan because increased pain indicates tissue remodeling
  4. Begin maximal eccentric Nordic curls immediately to prevent future strain
Explanation: This question tests the ability to modify intervention plans based on patient response and changing clinical status, a key skill for NPTE. Understanding how to adapt treatment plans involves recognizing when interventions are ineffective and knowing when to employ alternative strategies. In this scenario, the worsening of acute hamstring strain after aggressive stretching suggests the approach is too provocative. Choosing to shift to relative rest and gradual loading is correct because it allows tissue healing while progressing safely. The distractor recommending added deeper stretching is incorrect because it could delay recovery, a common mistake in acute strains. Teach students to carefully evaluate pain responses in early rehabilitation. Encourage understanding of evidence-based strain management and the importance of individualized care plans.

Question 9

What does increased spasticity after fast stretching indicate about intervention dosing in stroke rehabilitation?

  1. The stretching speed is appropriate and should be increased to reduce tone
  2. The intervention is provoking tone; use slower prolonged stretching and task-specific training (correct answer)
  3. Spasticity increase is unrelated; focus only on cardiovascular conditioning
  4. The patient needs maximal strengthening of spastic muscles to eliminate clonus
Explanation: This question tests the ability to modify intervention plans based on patient response and changing clinical status, a key skill for NPTE. Understanding how to adapt treatment plans involves recognizing when interventions are ineffective and knowing when to employ alternative strategies. In this scenario, the increased spasticity after fast stretching in stroke rehabilitation indicates velocity-dependent provocation. Choosing that the intervention is provoking tone and to use slower stretching is correct because it minimizes reflex responses. The distractor about increasing stretching speed is incorrect because it could heighten spasticity, a common mistake in neuro rehab. Teach students to carefully evaluate tone responses to dosing. Encourage understanding of evidence-based spasticity management and the importance of individualized care plans.

Question 10

What modification should be made after cervical traction increases dizziness and nausea during treatment session?

  1. Increase traction force and duration to improve decompression effects
  2. Stop traction, screen for vertebrobasilar insufficiency signs, and notify referring provider (correct answer)
  3. Continue traction but add rapid cervical manipulation to restore mobility
  4. Ignore symptoms and progress to resisted cervical rotation strengthening immediately
Explanation: This question tests the ability to modify intervention plans based on patient response and changing clinical status, a key skill for NPTE. Understanding how to adapt treatment plans involves recognizing when interventions are ineffective and knowing when to employ alternative strategies. In this scenario, the increased dizziness and nausea after cervical traction suggest potential vascular or neurological involvement. Choosing to stop traction, screen for vertebrobasilar insufficiency, and notify the provider is correct because it ensures patient safety. The distractor recommending increased traction force is incorrect because it could heighten risks, a common mistake when ignoring red flags. Teach students to carefully evaluate adverse responses during cervical interventions. Encourage understanding of evidence-based screening and the importance of individualized care plans.

Question 11

A physical therapist is treating a 45-year-old female with adhesive capsulitis of the right shoulder. The plan of care includes grade III and IV glenohumeral joint mobilizations to improve external rotation and abduction. After the third session, the patient reports a significant decrease in pain but also a new feeling of instability and apprehension when reaching overhead. Active range of motion for external rotation has increased from 20 degrees to 65 degrees.

Given the patient's report and objective changes, which modification to the intervention plan is MOST appropriate?

  1. Continue with grade IV mobilizations to maximize range of motion gains before the capsule stiffens again.
  2. Discontinue all manual therapy and focus solely on cryotherapy and patient education to manage the instability.
  3. Transition from high-grade mobilization to rotator cuff and scapular stabilization exercises within the newly gained range. (correct answer)
  4. Refer the patient for an orthopedic consultation to rule out a rotator cuff tear before proceeding with therapy.
Explanation: The patient's report of apprehension and instability, despite improvements in range of motion, suggests that the mobilizations have successfully increased capsular mobility but she now lacks the requisite dynamic stability to control this new range. This is a common clinical scenario in treating adhesive capsulitis. The most appropriate modification is to shift the focus from aggressive passive stretching (high-grade mobs) to neuromuscular re-education and strengthening to control the motion. Continuing aggressive mobilization (A) could exacerbate the instability. Discontinuing all manual therapy (B) is an overcorrection and fails to utilize the new range. While a referral (D) might be considered if a tear is strongly suspected, the classic presentation of apprehension with newfound motion points towards a need for stability training first.

Question 12

A physical therapist is treating a 50-year-old male with chronic lymphedema of the left lower extremity. The intervention consists of manual lymphatic drainage (MLD) followed by multi-layer short-stretch compression bandaging. During the MLD session, the therapist notes that the patient's limb, which is typically soft and pitting (Stage 2), now feels hard and fibrotic, and the patient reports new aching pain in the inguinal region.

What is the MOST appropriate modification to the plan of care based on these findings?

  1. Continue with MLD but apply deeper pressure to break up the newly developed fibrotic tissue.
  2. Discontinue MLD and apply a high-pressure, long-stretch bandage to reduce the limb volume quickly.
  3. Stop the MLD session, assess for signs of infection or proximal obstruction, and contact the referring physician. (correct answer)
  4. Focus the MLD treatment exclusively on the proximal inguinal area to clear the suspected blockage.
Explanation: A sudden change in tissue texture from soft and pitting to hard and fibrotic, especially when accompanied by new proximal pain, is a red flag. It suggests a potential proximal obstruction (e.g., DVT, tumor recurrence, or infection/cellulitis) that is preventing lymphatic drainage. Continuing MLD (A, D) could be harmful by pushing fluid against an obstruction or spreading infection. Applying high-pressure long-stretch bandages (B) is contraindicated in lymphedema. The safest and most appropriate action is to stop treatment, screen for red flags (e.g., check for warmth, erythema, fever for cellulitis; perform Wells criteria for DVT), and immediately communicate these significant changes to the physician.

Question 13

A patient recovering from a traumatic brain injury (TBI) is classified as Rancho Los Amigos Level V (Confused, Inappropriate, Non-Agitated). The therapy session is focused on simple, goal-directed tasks such as stacking cones. Midway through the session, the patient becomes increasingly perseverative on one component of the task and is easily distracted by ambient noise in the gym. They are unable to follow new commands.

Which is the MOST appropriate modification for the physical therapist to make?

  1. Move the patient to a quiet, private treatment room and re-engage them in the same, familiar task. (correct answer)
  2. Introduce a more complex, dual-task activity to challenge the patient's attention.
  3. Discontinue the session for the day as the patient is demonstrating cognitive fatigue.
  4. Use a loud, firm voice to provide directive cues and redirect the patient's attention back to the task.
Explanation: When treating patients with traumatic brain injury, understanding the Rancho Los Amigos levels helps guide appropriate interventions. Level V patients demonstrate confused, inappropriate behavior without agitation, meaning they can participate in activities but struggle with attention, memory, and processing new information. The correct approach is A - moving to a quiet environment while continuing the familiar task. This patient is showing classic signs of overstimulation: perseveration (getting stuck on one task component) and distractibility from ambient noise. Level V patients benefit from structured, distraction-free environments and familiar activities they've already started learning. By reducing environmental stimuli while maintaining the same task, you're addressing the root cause of their behavioral changes without overwhelming them with new demands. B is counterproductive because introducing complex dual-tasks would further overwhelm an already overstimulated patient. Level V patients lack the cognitive flexibility for increased complexity when they're struggling with basic attention. C assumes cognitive fatigue is the primary issue, but the patient's symptoms point to overstimulation rather than true fatigue. Discontinuing therapy wastes valuable treatment time when simple environmental modifications could allow continuation. D would likely worsen the situation since loud, firm voices can increase agitation and confusion in TBI patients. Level V patients respond better to calm, consistent approaches rather than authoritative redirection. NPTE Strategy: For Rancho level questions, match your intervention intensity to the patient's cognitive level and always consider environmental modifications before changing task difficulty or discontinuing treatment. Environmental control is often the first-line intervention for attention and behavioral issues in TBI recovery.

Question 14

A 40-year-old patient with vestibular neuritis is performing gaze stability exercises (VOR x1 viewing). The patient is able to maintain focus on a stationary target while moving their head side-to-side at 120 beats per minute without symptoms. However, when they attempt to walk down a hallway, they report significant oscillopsia (visual blurring) and dysequilibrium.

Which of the following represents the MOST appropriate progression and modification of the intervention?

  1. Increase the head speed during the seated VOR x1 exercise to 180 beats per minute.
  2. Discontinue VOR exercises and focus on static balance activities on compliant surfaces.
  3. Have the patient perform VOR x1 exercises with their eyes closed to enhance proprioceptive input.
  4. Progress the gaze stability exercise to include walking while maintaining focus on a stationary target. (correct answer)
Explanation: When treating vestibular disorders, the key principle is task-specific progression - you must bridge the gap between controlled exercises and real-world functional activities. This patient demonstrates a classic disconnect: they can perform gaze stability in a controlled seated environment but struggle with the same visual demands during walking. The correct approach is D - progressing to walking while maintaining focus on a stationary target. This directly addresses the patient's functional deficit by combining the vestibular challenge (head movements during gait) with the visual stability task they've already mastered in sitting. This progression follows the principle of adding complexity gradually while maintaining the core therapeutic exercise. A is incorrect because simply increasing head speed doesn't address the postural and locomotor demands that trigger the patient's symptoms during walking. Speed isn't the limiting factor here - functional context is. B abandons the successful gaze stability work entirely, which would be counterproductive since the patient needs continued VOR training, just in a more challenging context. C misses the point completely - the patient's problem is visual (oscillopsia), so removing visual input won't help them learn to maintain visual stability during movement. NPTE Strategy: Vestibular rehabilitation questions often test your understanding of progressive loading. When a patient succeeds at one level but fails at a higher functional level, the answer typically involves bridging that gap systematically, not abandoning successful interventions or jumping to unrelated activities. Look for progressions that add real-world complexity while maintaining the therapeutic target.

Question 15

A patient with type 1 diabetes is engaged in a moderate-intensity aerobic exercise session. The patient tested their blood glucose before the session and it was 130 mg/dL. Twenty minutes into the workout, the patient begins to show signs of confusion, pallor, and poor coordination. They are still conscious and able to swallow.

What is the MOST appropriate immediate action for the physical therapist to take?

  1. Stop the exercise, check the patient's blood glucose, and provide 15 grams of a fast-acting carbohydrate. (correct answer)
  2. Administer an emergency glucagon injection and call 911.
  3. Have the patient rest for 5 minutes and then resume exercise at a lower intensity.
  4. Provide a protein-rich snack to stabilize blood sugar over a longer period.
Explanation: When you encounter a diabetic patient showing sudden confusion, pallor, and poor coordination during exercise, you're likely witnessing hypoglycemia (low blood sugar). Exercise increases glucose uptake by muscles, which can rapidly drop blood glucose levels, especially in Type 1 diabetics who rely on insulin injections. The correct approach is A) Stop the exercise, check the patient's blood glucose, and provide 15 grams of a fast-acting carbohydrate. This follows the "15-15 rule" for conscious hypoglycemic patients: give 15 grams of fast-acting carbs (like glucose tablets or juice), wait 15 minutes, then recheck. Since the patient is conscious and can swallow, oral treatment is appropriate and faster than waiting for emergency services. B) Administering glucagon and calling 911 is reserved for unconscious patients or those who cannot swallow safely. Glucagon is an emergency measure when oral intake isn't possible, making this excessive for a conscious patient. C) Having the patient rest briefly then resume ignores the signs of hypoglycemia entirely. The symptoms indicate a medical emergency requiring immediate glucose replacement, not just exercise modification. D) Providing protein-rich snacks addresses long-term blood sugar stability but won't resolve acute hypoglycemia. Fast-acting carbohydrates are needed for immediate glucose elevation, while protein works over hours, not minutes. For the NPTE, remember that hypoglycemia symptoms during exercise require immediate action with fast-acting carbohydrates for conscious patients. Always stop activity first, assess blood glucose if possible, and treat appropriately based on consciousness level and ability to swallow.

Question 16

An 80-year-old female with severe vertebral osteoporosis is performing gentle, supervised resistance training for posture and balance. The plan includes exercises such as seated rows with a light resistance band. During the session, while reaching for the band, the patient reports a sudden, sharp, and localized pain in her mid-thoracic spine, followed by an inability to stand upright without severe pain.

What is the MOST appropriate immediate action for the physical therapist?

  1. Apply superficial heat to the area of pain and continue with gentle upper extremity AROM.
  2. Instruct the patient in deep breathing and relaxation techniques to manage the muscle spasm.
  3. Place the patient in a supported, comfortable position, discontinue the session, and arrange for immediate medical evaluation. (correct answer)
  4. Perform gentle grade I oscillations to the painful thoracic segment to modulate the pain.
Explanation: A sudden onset of severe, localized spinal pain during a minor movement in an elderly patient with severe osteoporosis is highly suspicious of an acute vertebral compression fracture. This is a medical concern that requires evaluation. Continuing with any form of exercise (A), performing manual therapy (D), or simply treating it as a muscle spasm (B) would be inappropriate and potentially harmful. The priority is to ensure the patient's safety and comfort, stop all therapeutic activity, and facilitate an immediate medical assessment to confirm or rule out a fracture.

Question 17

A physical therapist is using intermittent pneumatic compression (IPC) on a patient with chronic venous insufficiency and associated edema. The pressure is set to 50 mmHg. After 10 minutes of treatment, the patient reports that their toes feel numb and have a bluish tinge. The therapist removes the sleeve and notes that the distal portion of the foot is cool to the touch and capillary refill is delayed at 4 seconds.

What is the MOST appropriate modification for the physical therapist to make?

  1. Lower the pressure to 30 mmHg and continue the treatment, as this is a common sensation.
  2. Stop the treatment immediately and assess the patient's Ankle-Brachial Index (ABI) before considering further use of IPC. (correct answer)
  3. Elevate the leg higher than the heart and reapply the IPC sleeve to improve venous and arterial flow.
  4. Change the IPC duty cycle to have a shorter inflation time and a longer deflation time.
Explanation: The patient's signs and symptoms (numbness, cyanosis, coolness, delayed capillary refill) are indicative of arterial insufficiency. The applied compression, while intended for venous return, is compromising arterial inflow to the distal extremity. This suggests the presence of underlying peripheral arterial disease (PAD), which is a major precaution or contraindication for IPC. The most critical action is to stop the treatment and perform a vascular screen, specifically an ABI, to quantify the level of arterial compromise. An ABI of <0.8 is a precaution, and <0.6 is a contraindication. Simply lowering the pressure (A), changing the duty cycle (D), or elevating the leg (C) does not address the fundamental safety concern of compressing a limb with poor arterial supply.

Question 18

A 55-year-old female is being treated for a burn on her anterior forearm that is now in the remodeling phase of healing. The intervention includes scar massage and active range of motion exercises for the wrist and elbow. The therapist notes the scar is becoming raised, red, and is extending beyond the original boundaries of the wound. The patient also reports increasing pruritus (itching).

Which modification to the intervention plan is MOST critical to implement?

  1. Initiate application of a silicone gel sheet and compression garment to be worn 23 hours per day. (correct answer)
  2. Increase the frequency and pressure of the scar massage to break down the excess collagen.
  3. Discontinue all interventions and refer the patient to a dermatologist for suspected skin cancer.
  4. Apply ultrasound therapy over the scar tissue before performing range of motion exercises.
Explanation: When you encounter a burn scar that's becoming raised, red, and extending beyond original wound boundaries with increasing itching, you're looking at signs of hypertrophic or keloid scarring. This represents abnormal collagen deposition during the remodeling phase and requires immediate intervention to prevent further progression. The correct answer is A because silicone gel sheets and compression garments are the gold standard first-line treatment for abnormal scar formation. These interventions work by maintaining hydration, creating an occlusive environment, and applying constant pressure to reorganize collagen fibers. The 23-hour wear time is crucial for effectiveness, allowing only brief removal for hygiene. Option B is dangerous because increasing massage pressure on an already inflamed, hypertrophic scar can actually stimulate more collagen production and worsen the condition. Aggressive manipulation may cause further tissue trauma and inflammation. Option C misinterprets the clinical presentation. The described symptoms are classic signs of abnormal scarring, not malignancy. While the scar appears "red and raised," this matches hypertrophic scar characteristics rather than cancerous changes. Unnecessary referral delays appropriate treatment. Option D introduces ultrasound therapy, which isn't indicated as a primary intervention for active hypertrophic scarring. While ultrasound may have benefits later in treatment, it doesn't address the immediate need to control abnormal collagen formation through pressure and occlusion. Remember: When you see signs of abnormal scar formation (raised, red, extending beyond boundaries, itching), think "pressure and occlusion first" - silicone sheets and compression are your primary tools to prevent progression.

Question 19

A 28-year-old rock climber is receiving therapy for medial epicondylalgia. The plan includes eccentric wrist flexor strengthening. The patient is performing the exercise correctly but reports that their symptoms have worsened, with pain now present at rest and during the night. A neurologic screen reveals diminished sensation over the medial one and a half digits and a positive Tinel's sign at the elbow.

Given these new findings, the physical therapist's MOST appropriate action is to:

  1. add iontophoresis with dexamethasone to the medial epicondyle to control the inflammation.
  2. continue with the eccentric program but at a lower intensity and frequency to reduce tissue stress.
  3. fabricate a cock-up splint for the wrist to rest the flexor-pronator muscle group.
  4. stop the eccentric exercises and modify the plan to include ulnar nerve gliding exercises and activity modification. (correct answer)
Explanation: When you encounter a patient with medial epicondylalgia who develops new neurological symptoms during treatment, you must recognize this as a potential complication requiring immediate plan modification. The key red flags here are diminished sensation over the medial one and a half digits (ulnar nerve distribution) and positive Tinel's sign at the elbow, indicating ulnar nerve involvement at the cubital tunnel. The correct approach is D - stopping eccentric exercises and incorporating ulnar nerve gliding with activity modification. The neurological findings suggest the original condition has progressed to include ulnar neuropathy, possibly due to inflammation or mechanical compression. Continuing aggressive strengthening could worsen nerve compression and delay healing. A is incorrect because iontophoresis addresses only inflammation at the epicondyle, ignoring the nerve involvement that's now the primary concern. B fails to recognize that any eccentric loading may continue irritating the compromised nerve, regardless of intensity reduction. C targets wrist positioning but doesn't address the ulnar nerve compression at the elbow, which is the source of the neurological symptoms. The cock-up splint might actually maintain the wrist in extension, potentially increasing tension on already irritated structures. NPTE Strategy: When neurological signs emerge during musculoskeletal treatment, always prioritize nerve protection over continuing the original intervention. Look for classic nerve distribution patterns - ulnar nerve affects the medial 1.5 digits, while a positive Tinel's at the elbow confirms cubital tunnel involvement. This pattern recognition will serve you well on examination questions.

Question 20

A patient is 4 days post-total hip arthroplasty (posterior approach) and is performing gait training with a standard walker. The physical therapist has been cueing the patient to maintain posterior hip precautions. During the session, the therapist notes the patient consistently demonstrates a Trendelenburg gait pattern (hip drop on the swing side) that was not present on the previous day. The patient denies any increase in pain.

What is the MOST appropriate modification to the intervention during this session?

  1. Progress the patient to a single point cane to challenge the hip abductors and promote strengthening.
  2. Discontinue gait training and focus on isolated, non-weight bearing gluteus medius strengthening.
  3. Recommend the patient undergo an EMG study to rule out superior gluteal nerve palsy.
  4. Add verbal and tactile cues to facilitate gluteus medius activation during the stance phase of gait. (correct answer)
Explanation: When you encounter a sudden onset gait deviation after hip surgery, your first priority is identifying the underlying cause and providing immediate therapeutic intervention rather than advancing exercises or ordering tests. The new Trendelenburg pattern suggests gluteus medius weakness or inhibition, which commonly occurs post-surgery due to surgical trauma, swelling, or muscle guarding. The most appropriate immediate response is option D - adding verbal and tactile cues to facilitate gluteus medius activation. This therapeutic cueing can help re-establish proper muscle firing patterns and compensate for temporary weakness without compromising healing tissues. Tactile cues over the gluteus medius and verbal reminders to "lift your hip" during stance phase directly address the problem. Option A is dangerous because progressing to a more challenging assistive device when weakness has developed could increase fall risk and compromise surgical healing. Option B is overly conservative - discontinuing functional training isn't necessary when you can modify the current intervention to address the issue. Option C suggests EMG testing for nerve injury, but this is premature; superior gluteal nerve palsy would more likely present immediately post-surgery rather than develop on day 4, and conservative intervention should be tried first. Remember that on the NPTE, when you see a new functional deficit in the acute post-operative period, look for answers that provide immediate therapeutic modification rather than dramatic changes in plan of care. The progression principle in rehabilitation means addressing problems at the current level before advancing or retreating to different interventions.
