CC denotes patients with Parkinson’s disease and camptocormia according to consensus-based diagnostic criteria [2]; PD, patients with Parkinson’s disease (without CC); CoP, centre of pressure; VEL_MED_AP, velocity of anteroposterior CoP displacement; VEL_MED_ML, velocity of mediolateral CoP displacement; value, Kruskal–Wallis test; P significant if <0.05; values with and in bold are considered statistically significant.
