Abstract Background Good balance depends on accurate and adequate information from the senses. One way to substitute missing sensory information for balance is with biofeedback technology. We previously reported that audio-biofeedback ABF has beneficial effects in subjects with profound vestibular loss since it significantly reduces body sway in quiet standing tasks. Methods In this paper we present the effects of a portable prototype of an ABF system on healthy subjects upright stance postural stability in conditions of limited and unreliable sensory information. Stabilogram diffusion analysis combined with traditional center of pressure analysis and surface electromyography were applied to the analysis of quiet standing tasks on a Temper foam surface with .
