Vibroacoustic Stimulation and Relaxation: Can Sound and Vibration Influence Stress-Related Responses?
Highlights A pilot study evaluated a 20-minute vibroacoustic stimulation session in healthy adults. After the intervention, participants showed a breathier vocal quality, a speech pattern associated in the study with greater physiological relaxation. The vibroacoustic group also avoided the increase in vocal tension and effort observed in the control group. The results suggest that vibroacoustic […]
Molecular Hydrogen and Recovery: Supporting Functional Recovery After Soft Tissue Injury
Highlights A pilot study evaluated 36 professional male athletes with acute soft tissue injuries. Adding hydrogen to standard treatment was associated with a faster return toward normal joint range of motion. The combination of oral and topical hydrogen also produced a greater reduction in plasma viscosity compared with standard treatment alone. The findings suggest that […]
Vacuum Therapy and Microcirculation: How Negative Pressure Influences Blood Flow and Tissue Oxygenation
Highlights Topical vacuum therapy significantly increased all four measures of skin microcirculation evaluated in the study. With intermittent vacuum application, local blood flow increased from 16.5 to 41.5 AU in 30 minutes and continued rising to 49 AU during the pressure-free period. Local oxygen saturation increased from 57% to 74%, remaining elevated after the vacuum […]
Auricular Vagus Nerve Photobiomodulation Improves Cognition, Mood, and Sleep in Adults with Mild Cognitive Impairment: A Randomized Double-Blind Clinical Trial
Highlights This randomized, double-blind, controlled clinical trial evaluated auricular vagus nerve photobiomodulation (PBM) in adults with mild cognitive impairment (MCI). Participants receiving auricular vagus nerve photobiomodulation demonstrated improvements in cognitive performance, with positive trends also observed for memory, mood, and sleep. The active treatment also improved delayed verbal memory, reduced depressive symptoms. Treatment consisted of […]
