Changes in functional brain organization and behavioral correlations after rehabilitative therapy using a brain-computer interface

Abstract: This study aims to examine the changes in task-related brain activity induced by rehabilitative therapy using brain-computer interface (BCI) technologies and whether these changes are relevant to functional gains achieved through the use of these therapies. Stroke patients with persistent upper-extremity motor deficits received interventional rehabilitation therapy using a closed-loop neurofeedback BCI device (n = 8) or no therapy (n = 6). Behavioral assessments using the Stroke Impact Scale, the Action Resear… Show more

“…Such pathways are very small remnants of neuronal pathways that were once much larger and are the compromised neurological and neuroanatomical profiles of typical BCI users that may exist following the neurological trauma which resulted in the user’s distal motor impairment. The possible recruitment of these vestigial pathways has the potential for the restoration of functional motor capacities, selection of letters from an array [2,20], or movement of a virtual cursor [7,12,21–26]. …”

“…Therapies that incorporate BCI devices can be explained by conventional learning theories and replication of the BCI-driven motor learning outcomes observed in the healthy brain [7,12,29]. Reinforcement of motor behaviors is a key mechanism evident in the training and use of BCI therapies.…”

“…They also used fMRI to measure brain activity in stroke patients in a simple tapping task before and after a BCI intervention, showing that task-based functional connectivity correlates with gain in the motor outcome. However they also gave a word of warning indicating that BCI therapy might produce both adaptive and maladaptive changes (Young et al, 2014c).…”
