*P < 0.1, **P < 0.05, ***P < 0.01. OR = Odds Ratio, 95%CI = 95% confidence interval, IQR = interquartile range, NDI = neurodevelopmental index, MP = muscle power, PC = persistent control, BD = bimanual dexterity, PWC = Physical Work Capacity.

¹ group unable to do stretch is compared to group able to do stretch.
