Bilateral robotic priming before task-oriented approach in subacute stroke rehabilitation: a pilot randomized...

Area of Science:

• Neurorehabilitation
• Robotics in Medicine
• Stroke Recovery

Background:

• Subacute stroke frequently results in motor impairments and disability.
• Task-oriented approaches are standard for stroke rehabilitation.
• Novel techniques are needed to enhance recovery outcomes.

Purpose of the Study:

• To evaluate the effectiveness of bilateral robotic priming combined with a task-oriented approach.
• To assess impacts on motor function, disability, daily activities, and quality of life in subacute stroke patients.

Main Methods:

• A randomized controlled trial was conducted in occupational therapy clinics.
• Thirty-one subacute stroke patients were randomized into a primed group (bilateral robotic priming + task-oriented approach) or an unprimed group (task-oriented approach alone).
• Interventions were administered for 90 minutes/day, 5 days/week for 4 weeks, with the primed group using a bimanual robot-aided device.

Main Results:

• Both groups showed significant improvements in most assessed outcomes over time.
• The primed group exhibited significantly greater improvement in self-reported strength (Stroke Impact Scale strength subscale, p = 0.012).
• A trend towards greater improvement in disability was observed in the primed group (modified Rankin Scale, p = 0.065).

Conclusions:

• Combining bilateral robotic priming with a task-oriented approach enhances self-reported strength and reduces disability compared to the task-oriented approach alone.
• The findings suggest potential benefits of integrating robotic priming into stroke rehabilitation protocols.
• Larger-scale studies are recommended to validate these results and explore optimal implementation strategies.
