Figure 4From: Influence of a portable audio-biofeedback device on structural properties of postural swayEffect of ABF on postural control strategy. SDA diagrams for one representative subject. Two conditions are reported: without ABF (black) and with ABF (gray). The behaviour of K and ΔTc used to parameterize the SDA diagrams is also shown. This figure suggests that, using ABF, subjects decrease the amount of sway by increasing the closed-loop (feedback) posture control.Back to article page
