Table 3 Means (standard deviations) of COP sway path lengths by FOA group, standing leg and age

From: Are oral health and fixed orthodontic appliances associated with sports injuries and postural stability in elite junior male soccer players?

FOA group Standing leg COP sway path lengths (mm) P-value (ES)
12–14 years M (SD) 15–17 years M (SD)
Current or past FOA Dominant leg 1240 (611) 1192 (485) 0.71 (0.09)
Non-Dominant leg 1156 (424) 1298 (478) 0.22 (0.31)
Never used a FOA Dominant leg 1396 (609) 1189 (536) 0.07 (0.36)
Non-Dominant leg 1322 (425) 1079 (366) 0.002 (0.61)
  1. Note: (Non-)Dominant leg = (non-)dominant leg for kicking the ball. Lower COP sway path lengths indicate better postural stability
