Therapeutic Exercise and Functional Rehabilitation Flashcards

During cardiac rehabilitation, which symptom warrants IMMEDIATE exercise termination?

Answer: Systolic blood pressure drop of greater than 10 mmHg during progressive exercise intensity

A decrease in systolic BP greater than 10 mmHg during progressive exercise (exertional hypotension) indicates cardiac inability to maintain cardiac output and is an absolute indication to stop exercise.

Which type of muscle fiber (Type I or Type II) is predominant in postural muscles and most recruited during low-intensity prolonged activities?

Answer: Type I (slow-twitch oxidative)

Type I (slow-twitch oxidative) fibers are fatigue-resistant, highly oxidative, and preferentially recruited for low-intensity, endurance, and postural activities via Henneman size principle.

Which spinal stabilization exercise progression is most appropriate for a patient with acute low back pain in the acute phase who has pain with active trunk movements?

Answer: Begin with gentle co-contraction exercises (transversus abdominis activation, multifidus training) in neutral spine

In the acute phase of low back pain, the first step is deep stabilizer activation (transversus abdominis, multifidus) in a neutral spine position before progressing to global muscle exercises.

The single-leg squat test (repetitions to fatigue at 60 degrees of knee flexion) is used to assess which quality in patients with patellofemoral pain?

Answer: Quadriceps endurance and neuromuscular control

The single-leg squat test (repetitions to fatigue at 60 degrees flexion) is used to assess quadriceps endurance and neuromuscular control as an outcome measure for patellofemoral pain syndrome rehabilitation.

Aquatic therapy offers which primary physiological advantage for patients with significant joint pain or weight-bearing restrictions?

Answer: Buoyancy reduces effective body weight, allowing exercise with decreased joint compression forces

Water buoyancy reduces effective body weight by up to 90% (at neck depth), allowing patients with severe arthritis, post-surgical restrictions, or pain to exercise with dramatically reduced joint loading.

A patient with multiple sclerosis presents with fatigue and weakness that worsens with heat exposure (Uhthoff phenomenon). Exercise recommendations should include:

Answer: Pre-cooling strategies (cool vest, cool environment) and moderate-intensity exercise with rest periods

Uhthoff phenomenon (MS symptom worsening with heat) is managed by pre-cooling strategies and scheduling exercise in cool environments. Evidence supports moderate aerobic and resistance exercise for MS.
