Brief Summary

Much recent interest was raised by the use of Action Observation Treatment (AOT) in stroke patients rehabilitation. AOT, well-grounded in neurophysiology, is an updated approach, based on mirror neuron system (MNS) used to rebuild motor function despite injuries by engaging the brain regions active during action execution in individuals with limited mobility. This project aims at identifying, for the first time in Italy, neurophysiological electroencephalographic (EEG) biomarkers able to predict rehabilitation outcomes and providing an innovative optimized AOT rehabilitation protocol for chronic Stroke outpatients. EEG will be recorded to identify the most effective stimuli, quantify changes/recovery, profile patients. Moreover, an innovative AOT home-based program will be implemented. The translational research results will ensure advances in the optimization and personalization of the rehabilitative process thus contributing to improve the quality of life of chronic stroke patients. Stroke is a leading cause of death and one of the greatest causes of long-term disability that interferes with a good quality of life. Nowadays the rehabilitation interventions are the major component of patient's care to achieve functional outcome. In the last few years, in order to improve Activity of Daily Living (ADL), new noninvasive strategies have emerged as rehabilitative treatments rather than traditional physical therapies. The Action Observation Treatment (AOT), supported by results collected through randomized controlled trials, is one of these. This new rehabilitation approach is based on the properties of the Mirror Neuron System (MNS; 11-13). The extensive research of the last 20 years on the human MNS (hMNS) showed its importance not only in action recognition but also in motor intentions and other social cognitive functions. Lastly, because recruited also in damage brain (18,19), the MNS is demonstrated to provide satisfactory rehabilitative outcomes. The AOT takes advantage of the opportunity to restore functions despite the patient's impairment and it seems to be a valid example of translational medicine from basic neuroscience to rehabilitation. To date, neurophysiological outcomes were never used for translational purposes aimed to the optimization of the therapy and no evidence, in Italy, related to the effectiveness of the home-based program were proposed.

Outcome Measures

Primary Outcomes (1)

  • Change in Fugl-Meyer (FM) Test

    The Fugl-Meyer Assessment (FMA) is a stroke-specific, performance-based impairment index. It is designed to assess motor functioning, balance, sensation and joint functioning in patients with post-stroke hemiplegia. It is applied clinically and in research to determine disease severity, describe motor recovery, and to plan and assess treatment. The scale is comprised of five domains and there are 155 items in total: * Motor functioning (the score ranges from 0 (hemiplegia) to 100 points (normal motor performance). Divided into 66 points for upper extremity and 34 points for the lower extremity. * Sensory functioning (from 0 to 24 points) * Balance (from 0 to 14) * Joint range of motion (from 0 to 44) * Joint pain (from 0 to 44 ) Scale items are scored on the basis of ability to complete the item using a 3-point ordinal scale where 0=cannot perform, 1=performs partially and 2=performs fully. The total possible scale score is 226.

    At baseline-day 0 (T0), the middle of the treatment-day 15 (T1), at the end treatment-day 30 (T2), and at the follow up visit-day 90 (2 months both for the hospital-based and for the home based program) (T3)

Secondary Outcomes (1)

  • Change in Frenchay Arm Test (FAT)

    At baseline-day 0 (T0), the middle of the treatment-day 15 (T1), at the end treatment-day 30 (T2), and at the follow up visit-day 90 (2 months both for the hospital-based and for the home based program) (T3)

Other Outcomes (7)

  • Change in Box and Block Test (BBT)

    At baseline-day 0 (T0), the middle of the treatment-day 15 (T1), at the end treatment-day 30 (T2), and at the follow up visit-day 90 (2 months both for the hospital-based and for the home based program) (T3)

  • Change in Modified Ashworth Scale (MSA)

    At baseline-day 0 (T0), the middle of the treatment-day 15 (T1), at the end treatment-day 30 (T2), and at the follow up visit-day 90 (2 months both for the hospital-based and for the home based program) (T3)

  • Change in Modified Bartel Index (mBI)

    At baseline-day 0 (T0), the middle of the treatment-day 15 (T1), at the end treatment-day 30 (T2), and at the follow up visit-day 90 (2 months both for the hospital-based and for the home based program) (T3)

Study Arms (2)

Experimental Group (EG)

EXPERIMENTAL

The Experimental Group (EG) will observe and execute/repeat Activities of Daily Living (ADL) actions.

Other: Action Observation Treatrment

Control Group (CG)

ACTIVE COMPARATOR

The COntrol Group (CG) will observe landscapes and perform the same actions observed by their peers but after verbal instructions.

Other: Observation of videos with Non Motor contents

Interventions

Participants will be asked to carefully observe the videos showing different daily actions. Each action will consist of 3 to 4 constituent motor acts. Each motor act will be presented for 3 minutes, totally lasting 12 min/video. At the end of each motor act presentation, participants will be asked to execute with the affected hand the observed motor sequence for 2 minutes (20 minutes/session). 10 daily actions will be recorded. Each video will be presented to participants twice a day, in order to complexity as judged by the experimenter. Only 1 typology of motor task per day for each condition, starting from the easiest and ending with the most complex action throughout 15 sessions spread on 5 weeks (3 sessions/week). Tasks will be based on some relevant activities of daily living belonging to at least one between feeding, self-care or external actions category on the affected side. Each session will last about 15 minutes and will be repeated twice a day, at least 60 minutes apart.

Also known as: AOT
Experimental Group (EG)

Participants will be asked to observe video clips with no specific motor content. Videos will concern scientific, geographical and historical issues. As for cases, video clips will be divided into three to four parts. At the end of each part, controls will execute the same actions as cases, in the same order. In this way cases and controls will undergo the same amount of motor practice and receive the same amount of visual stimulation, the only difference being the content of visual stimuli.
