Effect of whole-hand water flow stimulation on the neural balance between excitation and inhibition in the primary somatosensory cortex

open access: yesFrontiers in Human Neuroscience, 2022
Sustained peripheral somatosensory stimulations, such as high-frequency repetitive somatosensory stimulation (HF-RSS) and vibrated stimulation, are effective in altering the balance between excitation and inhibition in the somatosensory cortex (S1) and ...

Changes in cognitive characteristics according to 3 intensity changes by 8 vibration frequencies (STROBE)

open access: yesMedicine, 2021
Abstract In this study, we attempted to observe changes in cognitive characteristics according to 3 intensity changes (Level 1: 0.25 gravity, Level 2: 0.38 gravity, Level 3: 1.3 gravity) at 8 vibration frequencies (10, 50, 100, 150, 200, 225, 250, 300 Hz).

EXPLORATION OF VIBROTACTILE BIOFEEDBACK STRATEGIES TO INDUCE STANCE TIME ASYMMETRIES

open access: yesCanadian Prosthetics & Orthotics Journal, 2021
BACKGROUND: Gait symmetry is the degree of equality of biomechanical parameters between limbs within a gait cycle. Human gait is highly symmetrical; however, in the presence of pathology, gait often lacks symmetry.
