Raw data of the accelerometers on top and the gyroscopes at the bottom.

<p>100 samples is one second. Blue are the vertical axes. green are the medio-lateral axes and red are the anterior-posterior axes. The numbers at the vertical lines correspond with the following events: 1 = Start SiSt. 2 = Maximum trunk flexion velocity SiSt. 3 = Maximum trunk flexion angle SiSt. 4 = Maximum trunk extension velocity SiSt. 5 = End SiSt. 6 = Start turn 1. 7 = End turn 1. 8 = Start turn 2. 9 = End turn 2. 10 = Start StSi. 11 = Maximum trunk flexion velocity StSi. 12 = Maximum trunk flexion angle StSi. 13 = Maximum trunk extension velocity StSi. 14 = End StSi.</p

Demographics and clinical assessments, and Trail Making Test performance.

<p>Good performers were defined as having a delta TMT score of less than 36 seconds, intermediate performers as having a delta TMT score of 36–58 s, and poor performers as having a delta TMT score higher than 58 s. Data are presented with median and range. P-values were assessed using the Kruskal Wallis test. P-values<0.05 were considered significant.</p><p>*p<0.05 compared to good performers;</p>#<p>p<0.05 compared to intermediate performers.
