The importance for training balance in connection with rehabilitation aimed at improving gait is easily stressed by considering the complex motor behaviour underpinning more challenging conditions than linear walking, as walking-and-turning, where the turn-related changes in feet, trunk and head movements are integral part of he kinematics of the steering body (Courtine and M. Schieppati, 2003; Crenna et al, 2007). It is no wonder that freezing of gait and increased risk of falling (Schlenstedt et al., 2016) is associated with abnormal bilateral coordination and turning. Hence, the present investigation somehow diverges from the theory of the task-specific training (Bayona et al., 2005), but considers instead the relevance for locomotion enhancement of training balance control, by hypothesising that specific balance rehabilitation might be sufficient for gait improvement. Here, we trained PD patients with two different treatments, both specifically addressing balance. A platform onto which subjects stood moved in antero-posterior, latero-lateral and diagonal direction in the horizontal plane. A simpler moving-platform protocol had been previously exploited for testing and enhancing balance capacities in patients with PD and with vestibular deficit (Nardone et al., 2010; De Nunzio 2007). This platform protocol challenges both the anticipatory and the reactive capacities to the ongoing postural perturbations, thereby training dynamic balance control, aiming at the balance problems encountered during every day activity.
