Neurotechnology-Based, Intensive, Supplementary Upper-Extremity Training for Inpatients With Subacute Stroke:...

Area of Science:

• Neurorehabilitation
• Stroke Recovery
• Motor Function Improvement

Background:

• Upper-extremity hemiparesis is a common post-stroke impairment, limiting daily activities and independence.
• Few stroke patients achieve full upper extremity recovery, highlighting the need for effective interventions.
• High-dose early training shows promise in animal models but faces challenges in human application.

Purpose of the Study:

• To assess the feasibility and potential efficacy of an intensive, video game-based upper-extremity training protocol.
• To evaluate the resources required for implementing this intervention in inpatient stroke rehabilitation.
• To improve movement quality and facilitate motor recovery through engaging, high-dose training.

Main Methods:

• Twelve patients with upper-extremity hemiparesis underwent a 4-week, 40-session intensive program (2 hours/day, 5 days/week) in addition to standard care.
• Two video game platforms were utilized: one for proximal (shoulder/elbow) and one for distal (wrist/finger) movements.
• Feasibility was measured by time on task, patient motivation, and engagement; efficacy was assessed using Fugl-Meyer Assessment (FMA-UE), Action Research Arm Test (ARAT), and Stroke Impact Scale (SIS).

Main Results:

• 8 out of 12 patients completed the full protocol; others completed a significant portion.
• Patients demonstrated high engagement (avg. 35-37 min/hour) and motivation (enjoyment score 6.49/7), with minimal pain (VAS 2.00/10).
• Significant improvements were observed in FMA-UE (+16.5 points), ARAT (+22.9 points), and SIS Hand Function (+1.23 points, +23.33% improvement).

Conclusions:

• An intensive, high-dose, video game-based training protocol is feasible and can be integrated into subacute stroke rehabilitation.
• Preliminary evidence suggests this supplementary intervention effectively enhances upper extremity motor recovery.
• This approach offers a promising, engaging, and high-intensity option for early stroke recovery programs.
