As described in the Parkinson's gait training scenario, which example best illustrates use-dependent feedback?

• A. Repetitive Stepping
• B. Cues For Step Length
• C. Various Surfaces
• D. Verbal Praise

Answer: (A)

Use-dependent feedback refers to changes in movement that come from repeatedly performing the same motor pattern, which strengthens the neural and sensory-motor pathways involved in that pattern. In Parkinson’s gait training, practicing the same stepping actions over and over directly trains the system to reproduce that pattern more reliably, embedding the walking pattern into the motor plan through repeated use. Repetitive stepping provides this kind of self-generated, practice-driven reinforcement, making it the best example of use-dependent feedback.

Cues for step length, on the other hand, offer external guidance to adjust a movement rather than letting the motor system solidify the pattern through repetition. Various surfaces introduce different task contexts to promote adaptability rather than reinforcing a single pattern through repetition. Verbal praise is motivational feedback and does not shape the motor pattern itself through repeated use.
