This observational trial aims to evaluate the effect of Rehabilitation on Postural Transfers (PTs) in subjects affected by Parkinson Disease. The PTs are evaluated by an inertial sensor (a device composed by an accelerometer, a gyroscope and a magnetometer) attached to the subjects. The data obtained by the inertial sensor are kinematic (e.g. acceleration and angular speed) and spatiotemporal parameters (e.g. time to completion and velocity). Additional clinical evaluations are carried out at the beginning and end of the rehabilitative intervention.

Inclusion Criteria:

• Subjects with Idiopathic Parkinson's Disease;
• Subjects should be in a positive therapeutic window or in the ON phase during the evaluations;
• Subjects must be able to walk at least 10 meters independently with or without any walking aid

Exclusion Criteria:

• Non-clinically stable subjects;
• Subjects in OFF phase during the evaluations;
• Other neurological conditions (e.g. stroke, peripheral neuropathies, etc.);
• Other pathologies that can negatively influence the subject's walking ability (e.g. surgery at the lower limbs in the previous 6 months, important deformities at the lower limbs, etc.)
