BACKGROUND: Post-traumatic disorders of consciousness (DoC) remain a major barrier to recovery after traumatic brain injury (TBI), yet therapeutic guidance is fragmented across modalities.
OBJECTIVE: To synthesize the highest-level evidence on efficacy and safety of interventions for TBI-related DoC and derive practice-oriented recommendations.
METHODS: Following PRISMA and a prospectively registered protocol (INPLASY202480015), we systematically screened PubMed, Embase, Web of Science, and CNKI through June 2024 for peer-reviewed systematic reviews and meta-analyses focused on TBI-induced DoC. Methodological quality was appraised using AMSTAR-2. Primary outcomes were CRS-R, GCS, GOS, and overall efficacy rate; random- or fixed-effects models were applied per heterogeneity.
RESULTS: Seven high-quality evidence syntheses encompassing 121 trials and eight interventions were included. Neuromodulation showed consistent benefits: repetitive transcranial magnetic stimulation (rTMS) improved CRS-R (MD 3.00, 95% CI 2.47-3.52) and GCS (MD 2.92, 1.65-4.19); transcranial direct current stimulation (tDCS) improved CRS-R (MD 2.08, 0.63-3.25). Peripheral and sensory approaches were robust: acupuncture improved GCS (MD 2.03, 1.54-2.52), GOS (RR 1.22, 1.16-1.29), and Efficacy Rate (RR 1.48, 1.40-1.56); multisensory stimulation improved GCS (MD 2.28, 2.02-2.54) and GOS (MD 1.11, 0.77-1.45). Right median nerve stimulation (RMNS) and family-centered sensory-affective stimulation also yielded significant gains, while single-study Trigeminal nerve stimulation (TNS) effects were mixed.
CONCLUSIONS: tDCS, rTMS, median nerve stimulation, multisensory stimulation, and acupuncture emerge as leading strategies for TBI-related DoC. We highlight priorities for the field: adequately powered multicenter RCTs with standardized protocols, mechanistic studies to refine dosing and targets, and predictive tools for personalized therapy selection. This umbrella synthesis provides a pragmatic evidence map to accelerate recovery and improve long-term outcomes in this vulnerable population.
