Sharpened Romberg Test and plantar pressure distribution system. (A) The SRT balance assessment comprises three stances: feet together, semi-tandem, and tandem. (B) The Footscan device from Rscan Company collected COP_x, COP_y, TTW, and EA when the participants’ feet were stationary and upright. COP_x and COP_y represent the displacement distances in the X- and Y-axis directions, respectively, caused by body offset during SRT, and are negatively correlated with balance ability. TTW denotes the total length of the moving trail generated by COP_x and COP_y during SRT tasks and is also negatively correlated with balance ability. Lastly, EA signifies the elliptical area surrounding 95% of the COP moving trail generated during SRT and is negatively correlated with balance ability (Mikolaizak et al., 2017).
