Fifteen patients with Parkinson's Disease will perform ten 45-minutes training sessions of the upper limb using the Armeo®Spring applied bilaterally, an electromedical device aimed at improving force and coordination in neurologically affected patients.

The device was built to sustain the forearm during the upper limb training and it is equipped with a VR screen with which the patient may interact during the playful and motivating rehab.

Fifteen patients with Parkinson's Disease will undergo ten 45-minutes training sessions of the upper limb with a traditional approach, performing the same excercises of the experimental group, i.e. flexo-extension of the wrist, prono-supination of the forearm, etcc.

To assess whether PD patients may got better results in the motor part of the UPDRS after the UL training

To evaluate if the patients will get better dexterity after the robotic training

to verify whether PD patients may present with an increase in muscle strenght after the treatment.
