Midterm Discussion Posts Flashcards
(32 cards)
What is acute denervation in EMG?
Spontaneous activity like fibrillations and sharp waves.
What is chronic denervation in EMG?
Longer, larger motor unit potentials, fewer units firing = reinnervation.
What conditions can show both acute and chronic denervation?
Progressive neuropathies such as ALS and chronic radiculopathy.
What does EMG measure?
Needle in muscle to measure activity at rest and contraction.
What does NCV test?
Electrical stimulation of nerves to test conduction speed.
What is recovery after a stroke?
Doing the task the same way as before.
What is compensation after a stroke?
New strategies to complete the same task, such as using the non-dominant hand.
What gait deviations occur during the pre/initial swing phase post-stroke?
Foot drop, poor knee/hip flexion leading to circumduction and hip hiking.
What gait deviations occur from mid swing to initial contact post-stroke?
Hamstring tightness leads to shorter step, forefoot contact, and vaulting.
What is Duchenne Muscular Dystrophy (DMD)?
An X-linked genetic disorder that starts in legs and progresses to trunk and arms.
What is pseudohypertrophy in DMD?
Enlarged calves due to fat or scar tissue.
When is DMD typically diagnosed?
At 2-4 years old, with a lifespan of approximately 30 years.
What is the late-stage focus of care for DMD?
Respiratory care, preventing contractures, and assistive devices.
What is the recommended bedrest after a lumbar puncture?
24 hours of bedrest is usually recommended.
What symptoms should be monitored after a lumbar puncture?
Headache, nausea, dizziness, back pain, and neurological changes.
What may help avoid deconditioning after a lumbar puncture?
Light bedside physical therapy.
What is a common gait deviation during the stance phase post-stroke?
Knee hyperextension due to weak quadriceps or hip extensors.
How can AFOs assist in gait deviations?
They help control foot position and knee stability.
What are KAFOs used for?
They may be needed for more stability, though they are rare in acute care.
What is the difference between pseudohypertrophy and true hypertrophy?
Pseudohypertrophy is when muscle looks big but is weak due to fat or scar tissue.
What is the recovery outlook for AIDP?
Good prognosis overall; 80% walk independently by 6 months.
What factors lead to a poorer prognosis in AIDP?
Older age, rapid onset, and infections such as Campylobacter.
What is the role of physical therapy in ALS care?
Enhances quality of life, focuses on function, comfort, and fall prevention.
What are treatment considerations for TKA with Myasthenia Gravis?
Avoid over-fatigue, alternate exercises, and monitor wound healing.
