Study: NCT03475355

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Live movement observation (Upper Limbs)
Description: All participants will be subjected to two 15-minute sessions per day of the Live movement observation of the upper limbs. The activities of the upper limbs will be based on some relevant activities of daily life such as drinking from a glass, combing, opening a box or eating an apple. The tasks will be both unimanual and bimanual.~Every day, before starting the physical training, the patient will be asked to look carefully at the therapist who shows 20 different daily routine activities (actions) performed with the upper limb.

Group type: EXPERIMENTAL
Intervention: Video Observation (Upper Limbs)
Description: All participants will be subjected to two 15-minute sessions per day of the video observation of upper limbs movements. The activities of the upper limbs will be based on some relevant activities of daily life such as drinking from a glass, combing, opening a box or eating an apple. The tasks will be both unimanual and bimanual.~Every day, before starting the physical training, the patient will be asked to carefully watch a video showing 20 different daily routine activities (actions) performed with the upper limb.

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Live Movement Observation (Lowe Limbs)
Description: All participants will be subjected to two 15-minute sessions per day of the Live movement observation of the lower limbs. Tasks to avoid freezing will be based on strategies such as touching the thigh, taking side or back steps, counting out loud while walking.~Every day, before starting the physical training, the patient will be asked to carefully watch the therapist who will show 20 different movement strategies to avoid episodes of freezing the pace (FOG).

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Video Observation (Lower Limbs)
Description: All participants will be subjected to two 15-minute sessions per day of the video observation of lower limbs movements. Tasks to avoid freezing will be based on strategies such as touching the thigh, taking side or back steps, counting out loud while walking. Every day, before starting the physical training, the patient will be asked to carefully watch a video that will show 20 different movement strategies to avoid episodes of freezing the pace (FOG).

Intervention type: BEHAVIORAL
Group type: ACTIVE_COMPARATOR
Intervention: Static Picture Observation and Upper Limbs Exercise
Description: Participants will watch for 3 minutes 5 static images that expose objects, none will represent animals or people.~The participant's attention will be kept high through a cognitive task. The patient will be presented a sequence of images for 3 minutes, the images will be displayed separately, each for 30 seconds, and then during the last 30 seconds, they will be displayed together with an intrusive image (intruder) that the patient you will be asked to identify so that your attention span can be controlled in real time. Participants will then be invited to perform limb movements as far as possible for 2 minutes according to a standard sequence involving joint mobilisations of upper limbs, and simulating that performed by the experimental groups.
