Neurofeedback Training for post-stroke rehabilitation for cognition and motor function

Stroke is a debilitating neurological condition that usually results in abnormal electrical brain activity and the impairment of sensation, motor, or cognition functions.

In this context, neurofeedback training, i.e., a non-invasive and relatively low-cost technique that contributes to neuroplasticity and behavioral performance, might be promising for stroke rehabilitation. We intended to explore neurofeedback training on a 63-year-old male patient and a 77-year-old female patient with chronic stroke. Both of them had suffered from an ischemic stroke for rather a long period (more than 3 years) and could not gain further improvement by traditional therapy. The neurofeedback training was designed to enhance alpha activity by 15 sessions distributed over 2 months, for the purpose of overall cognitive improvement and hopefully also motor function improvement for the female patient. We found that the two patients showed alpha enhancement during NFT compared to eyes open baseline within most sessions. Furthermore, both patients reduced their anxiety and depression levels. The male patient showed an evolution in speech pattern in terms of naming, sentences completion, and verbal fluency, while the female patient improved the functionality of the march. These results suggested that alpha neurofeedback training could provide a spectrum of improvements, providing new hope for chronic stroke patients who could not gain further improvements through traditional therapies.
