A Paradigm Shift: Rehabilitation Robotics, Cognitive Skills Training, and Function After Stroke

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Robotics

Background:

• Robot-assisted therapy (RT) offers modest gains for post-stroke upper extremity (UE) impairments.
• Improved UE performance in daily activities requires enhanced motor learning and neuroplasticity strategies.
• Current RT lacks focus on active problem-solving and skill transfer to real-world tasks.

Purpose of the Study:

• To pilot and assess the feasibility of the Active Learning Program for Stroke (ALPS).
• ALPS aims to complement existing robot-assisted therapy for the paretic UE.
• To integrate cognitive strategies and a home action plan for UE self-management and skill transfer.

Main Methods:

• Ten participants with chronic moderate UE impairment post-stroke received 18 sessions over 6-8 weeks.
• Participants received ALPS training alongside either robot-assisted therapy (RT) or robot therapy and task-oriented training (RT-TOT).
• The study compared the effectiveness of RT versus RT-TOT in reinforcing ALPS strategy implementation.

Main Results:

• Statistically significant improvements in Fugl-Meyer Assessment (FMA-UE) were observed favoring the RT group at discharge and follow-up.
• The ALPS protocol demonstrated significant moderate to large effects on FMA-UE, Motor Activity Log, Wolf Motor Function Test, and Stroke Impact Scale.
• No significant differences were found between RT and RT-TOT groups, suggesting ALPS benefits were independent of task-oriented training.

Conclusions:

• The ALPS protocol is the first to incorporate cognitive strategy training into robot-assisted therapy for UE recovery.
• The pilot intervention was feasible, well-tolerated, and showed potential for optimizing UE performance post-stroke.
• ALPS may enhance self-management and skill transfer, improving functional outcomes beyond traditional robot-assisted therapy.
