Evoked potentials in rehabilitation. A review

Area of Science:

• Neuroscience
• Rehabilitation Medicine
• Clinical Neurophysiology

Background:

• Rehabilitation is a rapidly expanding multidisciplinary field.
• Evoked potentials (EPs) and event-related potentials (ERPs) show promise as tools for prognosis, longitudinal monitoring, and assessing cortical remodeling.
• Despite their potential, the application of EPs and ERPs in rehabilitation literature is underexplored.

Purpose of the Study:

• To review the current achievements and applications of evoked and event-related potentials in the field of rehabilitation.
• To highlight the prognostic value of EPs and ERPs.
• To discuss their utility in longitudinal monitoring and potential for cortical remodeling.

Main Methods:

• This study is a review of existing literature on evoked and event-related potentials in rehabilitation.
• Key findings regarding prognostic indicators and monitoring capabilities were synthesized.
• The potential for training these potentials for therapeutic benefit was examined.

Main Results:

• Stable absence of bilateral somatosensory evoked potentials in hypoxic-ischemic coma indicates a poor outcome.
• Return of mismatch negativity is a strong indicator of good outcome.
• Event-related potentials are more suitable for prognostic purposes and reveal non-linear recovery trajectories that may exceed functional recovery.

Conclusions:

• Evoked and event-related potentials are valuable tools for prognosis and monitoring in rehabilitation.
• Electrical correlates of language represent a novel area for rehabilitation research.
• The possibility of training EPs and ERPs suggests a pathway to enhance cortical remodeling and improve rehabilitation outcomes.
