Abstract
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.

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 induce neural plasticity in individual with stroke promoting activation of the damaged motor circuits
The aim of this study is to find the effectiveness of action observation training to improve the upper limb motor function in acute stroke participants
Summary
Action Observation (AO) is a multisensory approach encompassing motor, somatosensory and cognitive rehabilitation. 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 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]. The aim of this study is to find the effectiveness of action observation training to improve the upper limb motor function in acute stroke participants
