An Examination of the Combined Effects of Multi-Modality Therapy on Cognitive Rehabilitation in Traumatic Brain Injury Patients

Abstract

This study investigates the combined effects of multi-modality therapy, including mild hyperbaric therapy (mHBT), photobiomodulation (PBM), and molecular hydrogen therapy (MH), on cognitive rehabilitation in individuals with mild-to-moderate traumatic brain injury (TBI). A total of 15 participants (7 males, 8 females, ages ranging from 20 to 78 years) diagnosed with mild-to-moderate TBI underwent 10 sessions of combined therapy. Cognitive performance was assessed using standardized neuropsychological tests before and after treatment, measuring cognitive processing speed, neural responsiveness, and executive function. The results demonstrated significant improvements across all metrics, including a 28.3 ms reduction in P300 latency, a 1.2 mV increase in P300 voltage, and reductions in completion times for the Trail-Making Tests A (14 seconds) and B (19 seconds). These findings suggest that multi-modality therapy may enhance cognitive recovery in TBI patients, with notable benefits across age and gender groups. Further research with larger sample sizes and extended follow-up is required to validate these results and explore their broader clinical applications.
