Which setup best exemplifies leveraging the practice principle in rehab robotics?

• A. Using robots to deliver high-frequency, repetitive training for motor recovery.
• B. Limiting practice to short, infrequent sessions.
• C. Relying on passive therapy only.
• D. Disregarding patient motivation.

Answer: (A)

The practice principle in rehab robotics centers on delivering a high dose of active, repetitive, task-specific practice to promote motor learning and neuroplastic changes. Robotic devices are particularly well-suited to this because they can safely provide many repetitions with consistent timing, precise movement, and immediate feedback, while often allowing assist-as-needed to keep the patient engaged and challenged.

Using robots to deliver high-frequency, repetitive training for motor recovery best exemplifies this principle because it maximizes the amount of meaningful practice a patient can perform in a session and across sessions, which is key for driving functional gains and neural adaptation.

Limiting practice to short, infrequent sessions reduces the total practice dose and slows learning. Relying on passive therapy does not require active motor engagement, limiting the potential for motor learning. Disregarding patient motivation undermines effort and adherence, which are essential for sustaining the high-dose practice that drives improvement.
