Summary

Noise stimulation had an immediate effect on improving balance control. The present study aimed to clarify the immediate neuromuscular adaptation induced by noise stimulation and find the correlation between neuromuscular adaptation and functional performance.

Detailed description

The mechanism behind noise stimulation is called Stochastic Resonance which improves the detectivity of sensory input with the presence of noise, making sub-sensory threshold input detectable. Noise stimulation had been proved to improve postural control, Ia afferent sensitivity, and muscle activity of the tibialis anterior. With this evidence of the effect of noise stimulation on balance enhancement, the neuromuscular adaptation induced by noise stimulation has not been researched yet. Therefore, the present study aims to clarify the immediate effect of noise on neuromuscular regulation during postural control.

Conditions

• Balanced
• Electroencephalography
• Electromyography
