Examples of surface area and COP path charts. Source: own research materials. An sample of the study charts is comprised in Fig. 3. - length of sway: determines the length of the COP trajectory in mm – COP length. - surface: surface area of the COP sway in mm² - COP field area. - mean X: mean value in mm of the COP trajectory in the X-axis - COP X mean. - mean Y: mean value in mm of the COP trajectory in the Y-axis - COP Y mean. - X axis: the range of COP movement in the X axis in mm in the mid-lateral direction of ML - COP X. - Y axis: the range of COP movement in the Y axis in mm in the antero-posterior direction AP - COP Y
