  • Noise‐enhanced balance control in patients with diabetes and patients with stroke
    Each insole received the same noise signal, the amplitude of which was set inde- pendently using potentiometers for each foot, from a small portable control box. The noise generator consisted of a single-chip record/playback device, in which a digitized white noise signal, low-pass filtered to 100Hz and distributed uni- formly in amplitude, was stored.
