PWR Parkinson's Disease-Specific Exercise Protocols 4 — Questions and Answers
Question 1: A PWR! Moves specialist is assessing a client with PD who exhibits micrographia and small, shuffling steps. These symptoms are best explained by which underlying motor impairment?
- Cerebellar ataxia causing dysmetria
- Impaired scaling of movement amplitude due to basal ganglia dysfunction (Correct answer)
- Upper motor neuron lesion causing spasticity
- Peripheral neuropathy reducing sensory feedback
Correct answer: Impaired scaling of movement amplitude due to basal ganglia dysfunction
Micrographia and festinating gait both reflect impaired amplitude scaling from basal ganglia dysfunction, causing the nervous system to generate movements that are consistently too small.
Question 2: Which form of exercise has been shown in research to potentially slow dopaminergic neuron degeneration and is emphasized in the PWR! approach?
- Stretching and flexibility training
- High-intensity aerobic exercise (Correct answer)
- Low-load resistance training
- Balance training alone
Correct answer: High-intensity aerobic exercise
High-intensity aerobic exercise has demonstrated potential neuroprotective effects by promoting BDNF and other neurotrophic factors that may slow dopaminergic degeneration.
Question 3: When a client with PD exhibits freezing of gait (FOG) at doorways, which PWR!-aligned intervention is MOST appropriate?
- Widen all doorways in the home environment only
- Use transverse lines on the floor as visual cues and practice step-over strategies (Correct answer)
- Discontinue walking exercise and transition to seated programs
- Increase dopaminergic medication dosage
Correct answer: Use transverse lines on the floor as visual cues and practice step-over strategies
Transverse visual cues (floor lines) at triggering locations and practicing step-over strategies are evidence-based exercise interventions for doorway-triggered FOG.
Question 4: Which PWR! Move is MOST directly associated with training the sit-to-stand transfer and lower extremity extensor power?
- PWR!Rock
- PWR!Twist
- PWR!Stand (Correct answer)
- PWR!Step
Correct answer: PWR!Stand
PWR!Stand trains the sit-to-stand movement pattern, developing the lower extremity extensor strength and weight-shifting strategy essential for this critical daily transfer.
Question 5: A person with PD in Hoehn and Yahr Stage 3 is beginning to show postural instability. Which balance training progression is MOST appropriate?
- Begin immediately with eyes-closed single-leg stance on foam
- Start with supported weight shifting and gradually reduce external support (Correct answer)
- Avoid all standing balance tasks and use seated balance only
- Use perturbation training at maximum challenge immediately
Correct answer: Start with supported weight shifting and gradually reduce external support
For Stage 3 PD with postural instability, start with supported weight shifting and progressively reduce support to safely challenge the postural system without unacceptable fall risk.
Question 6: What is the primary reason that PWR! Moves emphasizes whole-body, large-amplitude movements rather than isolated limb exercises?
- Isolated exercises are too fatiguing for PD patients
- Whole-body movements promote global sensorimotor recalibration and functional carryover (Correct answer)
- Large movements are easier for patients to perform
- Isolated exercises have no therapeutic benefit in PD
Correct answer: Whole-body movements promote global sensorimotor recalibration and functional carryover
Whole-body large-amplitude movements provide global sensorimotor recalibration and have better functional transfer to real-world activities than isolated limb exercises in PD.
Question 7: In PWR! programming, what does the concept of 'amplitude focus' primarily aim to achieve?
- Maximizing cardiovascular output per session
- Training patients to consciously generate movements larger than they perceive as necessary (Correct answer)
- Teaching patients to slow down their movements for safety
- Reducing the amplitude of tremor through proprioceptive feedback
Correct answer: Training patients to consciously generate movements larger than they perceive as necessary
Amplitude focus trains patients to consciously and consistently overshoot their perceived normal movement size because PD impairs amplitude perception, making normal-feeling movements actually too small.
