Description
Objective: Balance dysfunction (BDF) is a common and understudied aftereffect of Traumatic Brain Injury (TBI). This study investigates the effects of a Computerized Biofeedback-based Balance (CBB) intervention through the analyses of task-relevant neurophysiological responses to help improve balance and postural control among TBI patients. Methods: A randomized controlled trial was conducted with a total of 18 TBI patients, 5 were excluded from a lack of data collection. Participants were randomly assigned to either a CBB intervention (NINT = 6) or a control group condition (no intervention; NCTL = 7). Task-relevant neurophysiological responses to platform perturbation were assessed through the use of s 64-channel EEG and 12-channel lower-limb EMG. In this presentation, we present the corticocortical functional connectivity between different EEG sources related to intervention-based changes. Results: Compared to the control group condition, the intervention group is expected to show greater increase from baseline to post-intervention in the amplitude of cortical activity in the paracentral region of the brain. Discussion: Knowledge of specific connectivity changes can inform the development of personalized intervention strategies to target specific neural pathways that are most affected in TBI patients.
