Associations between Tactile Sensory Threshold and Postural Performance and Effects of Healthy Aging and Subthreshold Vibrotactile Stimulation on Postural Outcomes in a Simple Dual Task

Figure 1

Schematic overview of the experimental setup. Participants received verbal cues to memorize and to recall (1-back task). Custom-made software was used to provide cues and to analyze responses. Vibration was provided via tactor devices embedded in a silicone rubber sole. The soles were connected to a control box (CB) containing the power supply. The control box received commands from custom-made software on a connected computer. Not pictured: A trigger signal from the NeuroCom system was used to initiate stimulus presentation and data collection for the cognitive task.
