Electrical stimulation methods and protocols for the treatment of traumatic brain injury: a critical review of preclinical research.

PMID 37098582WHAT IT FOUND
Preclinical reviews of electrical stimulation in animal models of traumatic brain injury report improvements in motor, cognitive, and arousal outcomes across four methods.
However, inconsistent protocols and a lack of long-term data in these animal studies prevent direct application to human clinical practice.
Key findings
01This review synthesizes preclinical literature on four electrical stimulation methods (TMS, tDCS, DBS, VNS) for traumatic brain injury to assess their translational value.
02The analyzed animal studies generally reported positive effects of electrical stimulation on motor function, cognitive deficits, and disorders of consciousness.
03Variability in stimulation parameters and treatment timing across the included studies makes it difficult to determine optimal clinical protocols.

What it does not show
The review focuses exclusively on preclinical animal data, which may not translate to human patients due to anatomical and physiological differences. There is substantial heterogeneity in the stimulation protocols used across the included studies, making it difficult to compare results or determine optimal treatment parameters. Few studies investigated long-term or persisting effects of stimulation after the cessation of treatment. The search was conducted in only two databases (PubMed and Web of Science), which may have missed relevant studies. Screening and data extraction were performed by a single investigator, introducing potential bias. Most animal models used male rats, limiting the generalizability of findings to females.
The easy way to misread this
Do not interpret the positive results in animal models as evidence that electrical stimulation is an effective or standardized treatment for traumatic brain injury in humans. The review explicitly notes that variability in protocols and the preclinical nature of the data prevent direct clinical application.
