Customized Noise-Stimulation Intensity for Bipedal Stability and Unipedal Balance Deficits Associated With Functional Ankle Instability
Stochastic resonance stimulation (SRS) administered at an optimal intensity could maximize the effects of treatment on balance. The objective of this study is to determine if a customized optimal SRS intensity is better than a traditional SRS protocol applying the same percentage sensory threshold intensity for all participants for improving double- and single-legged balance in participants with or without functional ankle instability (FAI). The authors examined double- and single-legged balance tests, comparing optimal SRS (SRS^sub opt1^) and SRS^sub 0^ using a battery of center-of-pressure measures in the frontal and sagittal planes. Data were organized into bins that represented optimal (SRS^sub opt1^), second (SRS^sub opt2^), third (SRS^sub opt3^), and fourth (SRS^sub opt4^) improvement over SRS^sub 0^. The SRS^sub opt1^ improved double-legged balance and transfers to enhancing single-legged balance deficits associated with FAI.
