Neurofeedback training improves the dual-task performance ability in stroke patients

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Biomedical Engineering

Background:

• Stroke often impairs information processing, leading to difficulties with dual-task activities.
• Restoring functional abilities, particularly for combined tasks, is crucial for daily living post-stroke.

Purpose of the Study:

• To investigate the efficacy of neurofeedback training on dual motor task performance in stroke patients.
• To assess the impact of neurofeedback on sensorimotor rhythm regulation and gait parameters.

Main Methods:

• Randomized controlled trial with 20 stroke patients (6 months post-stroke) assigned to neurofeedback or pseudo-neurofeedback groups.
• 8-week intervention including general exercise; neurofeedback group received sensorimotor rhythm reinforcement.
• Electroencephalography (EEG) and SmartStep system used to analyze sensorimotor rhythm, dual-task ability, and gait parameters (velocity, cadence).

Main Results:

• Neurofeedback group demonstrated significant improvements in sensorimotor rhythm regulation (p < 0.001) and dual-task execution (p < 0.01).
• Significant enhancements in gait velocity and cadence (p < 0.05) were observed in the neurofeedback group.
• Pseudo-neurofeedback group did not show comparable improvements.

Conclusions:

• Neurofeedback training is an effective intervention for improving dual-task performance in stroke survivors.
• This approach shows potential for enhancing sensorimotor control and gait function following a stroke.
• Further research could explore long-term effects and optimal neurofeedback protocols for stroke rehabilitation.
