Study: NCT04604171

Intervention type: BEHAVIORAL
Group type: EXPERIMENTAL
Intervention: Action Observation Training
Description: Action Observation Training (AOT) is composed, according to Franceschini et al. (2012), by 20 different videos of daily activities (actions) carried out with the upper limbs. Patients underwent only one task per day for 20 sessions, starting from the easiest. Each action (unimanual or bimanual) is observed from a first-person perspective. Actors in the videos are young non-disabled people, either men or women. Patients are asked to carefully observe the videos, in order to prepare themselves to imitate the presented actions, while the therapist consistently holds the patient's attention with verbal feedback. At the end of each sequence, the therapist prompts the patient to perform the same movement with the paretic upper limb over a time period of 2 minutes, providing verbal instructions or help, if needed. Each session lasts about 30 minutes (3 min of sequence observation and 2 min of action performance for 3 motor sequences repeated twice).

Intervention type: BEHAVIORAL
Group type: ACTIVE_COMPARATOR
Intervention: Task Oriented Training
Description: In Task Oriented Training patients performed functional activities with the upper limbs, using the same objects for AOT, in both unimanual and bimanual modalities, without watching the video beforehand. The therapist just provided for verbal instructions and feedback, avoiding demonstrative or imitative indications. The therapist could passively support the movement if patients were completely unable to perform the actions. When necessary, the therapists could also actively facilitate the upper limb movement if patients were unable to correctly perform the actions. Based on the patient's level of motor ability and progress, the levels of movement and task difficulty could be adjusted accordingly. Patients underwent one task per day for 20 sessions. Each session lasted about 30 minutes.

Intervention: Conventional Treatment
Description: Conventional treatment consists of a range of different patient-tailored interventions, selected by the therapist on the basis of the functional level of the patient. Treatment sessions include training for transfers, mobility, walking up and down steps, balance tasks and tailored functional tasks for the upper limbs (unimanual and bimanual). Moreover, it is also provided for joint and soft tissue mobilization, specific sensory stimulation, exercises to increase strength, both for lower and upper limbs. Each session lasted about 60 minutes.
