PWR PWR Moves Fundamentals & Amplitude Training 2 — Questions and Answers
Question 1: Amplitude training in PWR! is derived from principles originally developed in which evidence-based intervention?
- Proprioceptive Neuromuscular Facilitation (PNF)
- LSVT BIG (Correct answer)
- Bobath Concept (Neurodevelopmental Treatment)
- Constraint-Induced Movement Therapy (CIMT)
Correct answer: LSVT BIG
LSVT BIG provided the foundational evidence for using high-amplitude, high-effort movement training to improve motor function in Parkinson's disease.
Question 2: Which cueing approach does PWR! recommend to help patients achieve appropriate movement amplitude?
- Eliminating all external cues to promote motor automaticity
- Using only auditory rhythm cues for movement timing
- Combining visual, auditory, and tactile cues to enhance movement awareness (Correct answer)
- Proprioceptive cueing exclusively through manual resistance
Correct answer: Combining visual, auditory, and tactile cues to enhance movement awareness
PWR! uses multimodal cueing — visual, auditory, and tactile — to increase movement salience and help patients achieve and internalize larger movement amplitudes.
Question 3: In PWR! programming, each of the four core moves can be practiced in which contexts?
- Standing only, as gravity loading is required for all moves
- Sitting only, to maximize safety in Parkinson's populations
- Supine (floor), sitting, standing, and walking (Correct answer)
- Supine and standing, but not sitting due to trunk instability
Correct answer: Supine (floor), sitting, standing, and walking
PWR! Moves are designed to be practiced across all functional positions — supine, sitting, standing, and walking — to maximize functional carryover.
Question 4: In PWR! neuroplasticity principles, 'salience' refers to which concept?
- The speed at which repetitions are performed during practice
- Making exercise meaningful and attention-demanding to the patient (Correct answer)
- The number of repetitions completed within a given session
- The resistance level applied during strengthening exercises
Correct answer: Making exercise meaningful and attention-demanding to the patient
Salience means the exercise must be meaningful and require focused attention from the patient, which is critical for driving neuroplastic adaptation.
Question 5: Which PWR Move is most foundational for improving sit-to-stand transitions in patients with Parkinson's disease?
- PWR Twist
- PWR Step
- PWR Rock
- PWR Up (Correct answer)
Correct answer: PWR Up
PWR Up, which focuses on anti-gravity extensor activation, is the foundational move for sit-to-stand and upright posture transitions.
Question 6: Reduced amplitude of movement in Parkinson's disease — where movements become smaller than intended — is clinically referred to as:
- Akinesia (absence of movement)
- Hypokinesia (reduced movement amplitude) (Correct answer)
- Bradykinesia (slowness of movement)
- Dyskinesia (involuntary movement)
Correct answer: Hypokinesia (reduced movement amplitude)
Hypokinesia specifically refers to decreased amplitude of voluntary movements, which is the primary deficit that amplitude training in PWR! targets.
Question 7: Why does PWR! programming incorporate each move across multiple positions (supine, sitting, standing, walking)?
- To increase session variety and prevent patient boredom
- To systematically progress difficulty and ensure functional carryover across all daily contexts (Correct answer)
- To isolate different muscle groups in each separate position
- To comply with insurance billing requirements for treatment time
Correct answer: To systematically progress difficulty and ensure functional carryover across all daily contexts
Practicing each move across positions systematically increases challenge while ensuring the movement pattern transfers to all functional contexts in daily life.
