Introduction: Brain computer interface-based action observation (BCI-AO) is a promising technique in detecting the user's cortical state of visual attention and providing feedback to assist rehabilitation. Peripheral nerve electrical stimulation (PES) is a conventional method used to enhance outcomes in upper extremity function by increasing activation in the motor cortex. In this study, we examined the effects of different pairings of peripheral nerve electrical stimulation (PES) during BCI-AO tasks and their impact on corticospinal plasticity.

Article Synopsis
  • - A 62-year-old man was hospitalized due to peripheral neuropathy and myositis symptoms, eventually leading to a diagnosis of polyarteritis nodosa (PAN) after further systemic symptoms emerged.
  • - Initially diagnosed with polymyositis and sciatic neuropathy, the patient's diagnosis changed when testicular pain prompted a reevaluation using established diagnostic criteria.
  • - Treatment involved over 6 months of glucocorticoids and antiviral medication for hepatitis B prevention, resulting in significant pain relief and no recurrence of symptoms.

Brain-computer interface (BCI) is a promising technique that enables patients' interaction with computers or machines by analyzing specific brain signal patterns and provides patients with brain state-dependent feedback to assist in their rehabilitation. Action observation (AO) and peripheral electrical stimulation (PES) are conventional methods used to enhance rehabilitation outcomes by promoting neural plasticity. In this study, we assessed the effects of attentional state-dependent feedback in the combined application of BCI-AO with PES on sensorimotor cortical activation in patients after stroke.
