Exoskeleton-assisted upper limb rehabilitation after stroke: a randomized controlled trial.

Area of Science:

• Neurorehabilitation
• Robotics in Medicine
• Stroke Recovery

Background:

• Stroke frequently impairs upper limb motor function, impacting daily living.
• Repetitive, task-specific training is crucial for motor recovery after stroke.
• Upper-limb exoskeleton technology offers a novel approach to enhance rehabilitation.

Purpose of the Study:

• To compare the efficacy of an upper-limb exoskeleton training program versus the Bobath concept.
• To evaluate the impact on upper limb motor functions in individuals with chronic stroke.

Main Methods:

• Randomized trial with 24 chronic stroke participants (12 per group: exoskeleton vs. Bobath).
• Interventions were matched for duration and frequency (2x/week for 6 weeks).
• Primary outcome: Fugl-Meyer Upper Extremity (FMA-UE); Secondary: Modified Ashworth Scale, Motor Activity Log (AOU/QOM), NEADL.

Main Results:

• Exoskeleton group showed significantly greater FMA-UE improvement (5.7 vs. 1.9 points, p<0.05).
• Higher rates of clinically meaningful improvement observed in the exoskeleton group for FMA-UE, AOU, QOM, and NEADL.
• Exoskeleton training demonstrated significant benefits in AOU, QOM, and NEADL compared to the Bobath group (p<0.05).

Conclusions:

• High-intensity, exoskeleton-assisted training is safe and feasible for stroke survivors.
• Exoskeleton-assisted training significantly enhances upper limb motor function and quality of life post-stroke.
• This approach represents a valuable advancement in neurorehabilitation strategies.
