Video feedback on functional task performance improves self-awareness after traumatic brain injury: a randomized...

Area of Science:

• Neurorehabilitation
• Cognitive Rehabilitation
• Clinical Psychology

Background:

• Self-awareness is crucial for rehabilitation outcomes in individuals with traumatic brain injury (TBI).
• Various feedback methods exist for enhancing self-awareness, but comparative data is lacking.
• Impaired self-awareness is a common challenge following TBI, impacting functional recovery.

Purpose of the Study:

• To compare the efficacy of different feedback modalities in improving impaired self-awareness post-TBI.
• To evaluate the impact of video plus verbal, verbal-only, and experiential feedback on self-awareness.
• To assess the effect of feedback interventions on secondary outcomes including intellectual awareness and emotional status.

Main Methods:

• A randomized, assessor-blinded trial with 54 participants with TBI and impaired self-awareness.
• Participants engaged in a meal preparation task and received one of three feedback interventions: video plus verbal, verbal, or experiential.
• Primary outcome measured online awareness via error reduction during task completion; secondary outcomes included intellectual awareness and emotional status.

Main Results:

• Video plus verbal feedback led to a significantly greater reduction in errors compared to verbal feedback alone (mean difference = 19.7 errors).
• The video plus verbal feedback group also showed a greater reduction in errors than the experiential feedback group (mean difference = 12.4 errors).
• Improvements in self-awareness were not associated with any negative changes in participants' emotional status.

Conclusions:

• Video plus verbal feedback is an effective method for enhancing self-awareness in individuals with TBI.
• This feedback approach can improve functional awareness during rehabilitation tasks.
• The findings support the use of multimodal feedback to address self-awareness deficits after TBI without adverse emotional effects.
