PWR Parkinson's Disease-Specific Exercise Protocols 3 — Questions and Answers
Question 1: Which of the following best describes the role of the PWR!Rock move in addressing Parkinson's disease motor symptoms?
- It trains explosive power for fall recovery
- It promotes weight shifting and postural transitions to combat rigidity (Correct answer)
- It focuses on fine motor coordination of the hands
- It specifically targets respiratory muscle strengthening
Correct answer: It promotes weight shifting and postural transitions to combat rigidity
PWR!Rock trains rhythmic weight shifting and postural transitions, which helps combat rigidity and improve the dynamic postural control impaired in PD.
Question 2: An individual with PD reports that their symptoms are notably worse in the late afternoon before their next medication dose. How should an exercise session be scheduled?
- Always exercise in the morning regardless of medication timing
- Schedule exercise during the ON state, typically 45–60 minutes after medication (Correct answer)
- Avoid all exercise during OFF periods entirely
- Exercise only in the evening to build tolerance to OFF-state symptoms
Correct answer: Schedule exercise during the ON state, typically 45–60 minutes after medication
Exercise should be scheduled during the ON state (45–60 minutes post-medication) when motor control is optimal, maximizing performance and safety.
Question 3: Which PWR! Move most directly trains the floor-to-stand transfer that is critical for fall recovery in Parkinson's disease?
- PWR!Twist
- PWR!Rock
- PWR!Move (floor work) (Correct answer)
- PWR!Step
Correct answer: PWR!Move (floor work)
PWR!Move floor work specifically trains the supine-to-stand sequence, addressing the critical safety skill of getting up from the floor after a fall.
Question 4: What is the primary mechanism by which treadmill training benefits gait in Parkinson's disease?
- Strengthening the tibialis anterior muscle
- Providing rhythmic somatosensory input and external pacing to normalize step length (Correct answer)
- Improving cardiovascular endurance exclusively
- Reducing spasticity in the lower extremities
Correct answer: Providing rhythmic somatosensory input and external pacing to normalize step length
Treadmill training provides consistent rhythmic somatosensory feedback and external pacing that helps normalize stride length and cadence in PD.
Question 5: A client with PD has a history of orthostatic hypotension. Which exercise modification is MOST appropriate?
- Eliminate all standing exercises from the program
- Allow adequate time for postural transitions and monitor blood pressure responses (Correct answer)
- Increase sodium intake only
- Perform all exercises in a hot environment to promote adaptation
Correct answer: Allow adequate time for postural transitions and monitor blood pressure responses
Slow postural transitions with blood pressure monitoring allow the cardiovascular system to compensate and reduce syncopal risk during exercise in PD patients with orthostatic hypotension.
Question 6: In the PWR! framework, which of the following represents the correct hierarchy for exercise skill acquisition in PD?
- Automatic → Attentional → Implicit
- Implicit → Explicit → Automatic
- Attentional (explicit) practice → automaticity through repetition (Correct answer)
- Random practice → blocked practice → transfer
Correct answer: Attentional (explicit) practice → automaticity through repetition
PWR! uses attentional (explicit) practice with conscious focus on movement amplitude first, then builds toward automaticity through high-repetition practice.
Question 7: Which type of cueing strategy relies on the patient using their own cognitive resources to trigger movement initiation in PD?
- External auditory cueing
- External visual cueing (floor stripes)
- Mental imagery and internal attentional cueing (Correct answer)
- Tactile cueing from a therapist
Correct answer: Mental imagery and internal attentional cueing
Internal attentional cueing, such as mental imagery of taking a big step, uses the patient's own cognitive resources to initiate movement by bypassing the defective automatic pathway.
