Task: Answer Verification
Input (English): Question: Does a shoe insole delivering subsensory vibratory noise improve balance and gait in healthy elderly people?
Answer: This study provides proof of concept that the application of the principle of stochastic resonance to the foot sole sensory system using a new low-voltage piezoelectric technology can improve measures of balance and gait that are associated with falls. Effective vibratory noise amplitudes range from 70% to 85% of the sensory threshold and can be set once daily.
Output (English): yes
