The outcome of the platform treatment was compared to that obtained in another group of matched patients with PD by standardized and validated exercises aimed at training balance and dynamic balance (Renfro et al., 2016). Of note, these exercises contained no dynamic component (i.e. gait-related exercises) of balance training, contrary to Conradsson et al. 2017. Both treatments (platform and exercises) were tailored to the patient individual capacities, and their difficulty gradually increased all along the duration of the treatment (Conradsson et al., 2017). In this context, we estimated any improvement in balance control by indexes of dynamic stability during a balance perturbation test on the mobile platform and by clinical scores related to dynamic balance control. Gait improvement was both evaluated instrumentally and assessed by a functional clinical test.
