“…39 However, the treatment protocols proposed by the AOT clinical trials are heterogeneous in terms of video content, time frame of action observation and execution, and treatment dose. 27 In the light of the potential effect of AOT in neurorehabilitation, it is necessary to determine which categories of actions can evoke a stronger cortical activation in the observer's brain.…”

Background The Action Observation Therapy (AOT) is a well-established post-stroke rehabilitation treatment based on the theoretical framework of the Mirror Neuron System (MNS) activation. However, AOT protocols are still heterogeneous in terms of video contents of observed actions. Objective The aim of this study was to analyze electroencephalographic (EEG) recordings in stroke patients during the observation of different videos of task-specific upper limb movements, and to define which category of actions can elicit a stronger cortical activation in the observer’s brain. Methods Signals were analyzed from 19 chronic stroke subjects observing customized videos that represented 3 different categories of upper limb actions: Finalized Actions, Non-Finalized Actions, and Control Videos. The Event-Related Desynchronization in the µ and β bands was chosen to identify the involvement of the cerebral cortex: the area of the normalized power spectral density was calculated for each category and, deepening, for the reaching and completion sub-phases of Finalized Actions. For descriptive purposes, the time course of averaged signal power was described. The Kruskal–Wallis test ( P < .05) was applied. Results The analysis showed a greater desynchronization when subjects observed Finalized Actions with respect to Non-Finalized in all recorded areas; Control videos provoked a synchronization in the same areas and frequency bands. The reaching phase of feeding and self-care actions evoked a greater suppression both in µ and β bands. Conclusions The observation of finalized arm movements seems to elicit the strongest activation of the MNS in chronic stroke patients. This finding may help the clinicians to design future AOT-based stroke rehabilitation protocols. Clinical Trial Registration: Clinical Trial Registration—URL: http://www.clinicaltrials.gov .

“…Functional recovery after stroke is known to be influenced by the size, type, and site of brain damage, as well as by the quality and intensity of the rehabilitation intervention. The current views on rehabilitation effectiveness advises to pursue the relearning of basic skills concerned with activities of daily living and to practice activities of daily living intensively in order to optimize the upper limb function [3]. Motor recovery after stroke occurs as a consequence of neural plasticity.…”

“…Motor recovery after stroke occurs as a consequence of neural plasticity. A range of neuro rehabilitation techniques aims to facilitate the occurrence of neural plasticity to overcome the functional impairments in affected individuals [3].Over the last few years; several approaches have been tested with respect to their efficacy at promoting hand dexterity recovery after stroke. Among them, task-oriented therapy, robotassisted rehabilitation, and action observation (AO) were paid the greatest attention for upper limb motor rehabilitation in individual with stroke [4].…”

“…It is hypothesized that the motor area engagement that occurs in real execution of action is the same taking place during observation of this action, and that action observation would therefore induce neural plasticity in individual with stroke promoting activation of the damaged motor circuits. For this reason it is suggested that this mirror neuronal system activation may serve as an alternative means to rearrange damaged, but not completely lost circuits thereby rebuilding voluntary function [3]. There are many literatures proved that AO strategy gives an improvement in recovery of motor function in chronic stroke participants [9].…”

Introduction: Action Observation (AO) is a multisensory approach encompassing motor, somatosensory and cognitive rehabilitation. Several Studies have proved the effects of action observation on recovery of motor functions in chronic stroke survivors. However, the effect of action observation strategy on acute stroke participants remains unclear. The objective of this study was to find out the effectiveness of action observation to improve upper limb function in acute stroke. Methods: 28 acute stoke participants were selected based on inclusion and exclusion criteria and randomly assigned into two groups based on computer generated randomization. Action observation training group (AO) received action observation training and conventional group received conventional physiotherapy. Both the groups received 45 minutes session per day for the total duration of 10 days. Results: Upper limb functions were measured using Fugl Myer upper limb component (FMA) and action research arm test (ARAT)at the baseline and after the intervention. Compared with the conventional training group, AO group showed significant improvement in ARAT but no significant difference between the groups in FMA. Conclusion: In conclusion Action observation treatment may become a useful strategy in rehabilitation of acute stroke participants.

“…Action Observation Therapy (AOT) is a novel rehabilitation strategy used in patients with neurological disorders such as cerebral palsy, Parkinson’s disease, and stroke ( 6 ). In this method, some movements and actions of healthy models are shown on a video or a live demonstration; then the patient must try to imitate and execute those actions ( 7 ).Neuroscientific studies have claimed that AOT's theoretical basis is on the evidence that observation of goal-directed action ( 8 ) activates the Mirror Neuron System (MNS), which is the same neural active mechanism while executing that action ( 6 ). Functional connections have been reported between mirror neuron areas and the motor cortex ( 9 ).…”

Background: Action Observation Therapy (AOT) is a top-down approach that has been recently introduced in the rehabilitation of neurological disorders mainly after stroke. The main goal of this study was to investigate the effects and feasibility of a new technique in AOT procedure (called self-AOT) following periods of no treatment and routine AOT intervention on upper limb motor function, occupational performance and neurophysiological changes in a stroke patient. Methods: A single-subject A-B-A-C design was used and a 58-year-old woman with a 3-year history of left hemiplegia poststroke participated in this study. In the baseline (A1, A2) phases, the patient received no treatment. In the first intervention (B phase), she received a 4-week AOT, and in the second intervention (C phase), a 4 week of Self-AOT was practiced. In all phases, upper limb motor recovery as a target outcome was evaluated on 4 occasions using the Fugl-Meyer assessment. Upper limb function, dexterity and spasticity were assessed using Action Research Arm Test, Box-Block Test and Modified Modified Ashworth Scale respectively. Occupational Performance/Satisfaction was assessed with Canadian Occupational Performance Measure and to assess neuroplasticity, Motor Evoked Potential was recorded by Transcranial Magnetic Stimulation. Visual analysis, slope, and percentage of non-overlapping data were used for assessing the changes between phases. Results: Percentage of non-overlapping data and slopes indicated that motor recovery had clinically relevant improvements after both interventions compared to baselines. Other outcomes also showed improvements except for spasticity of wrist/elbow flexors and Motor Evoked Potential of opponens indicis. Conclusion: Self-AOT may be as effective as other procedures of AOT for improving upper limb motor function, occupational performance/satisfaction, and cortical excitability post-stroke.
