The patients in the action observation therapy group will be required to observe the upper limb movements or functional actions in video clips. (i.e., the observation phase) and to execute what they had observed to the best of their ability (i.e., the execution phase). Three common categories of movements and tasks will be elected in the action observation therapy protocol based on the related literature

During the mirror therapy, the patients will be seated in front of a mirror box placed at their mid-sagittal plane. The affected arm of the participants will be placed inside the mirror box and the unaffected arm in front of the mirror. The patient will be instructed to watch the mirror reflection of the movement performed by his/her unaffected hand carefully and to imagine that the movement was performed by the affected hand.

following phases will be included in action observation therapy group:

1. upper limb active range of motion (AROM) exercises.
2. reaching movement or object manipulation.
3. upper limb functional tasks.

An assessment scale for post stroke hemiplegic patients and is performance-based impairment index. This scale is having 5 domains namely Motor functioning, Sensory Functioning, Balance, Joint Range of Motion and Joint pain. I divided the motor functioning for upper extremity into 0 to 66 points and evaluates mobility, speed and coordination

This test is used to evaluate the manual dexterity of post stroke patients. BBT is composed of wooden box with two equal compartments having 150 boxes in one compartment and patient is asked to move the boxes from one compartment to another within 60 seconds. Before starting the test an extra 15 seconds time is given to the patient for familiarization with the test. First the patient performed the activity with the healthy arm and then with the affected arm. Scoring is done on the basis of the number of boxes transferred from one compartment to another within 60 seconds

The FIM is a commonly used scale for assessing the performance in basic daily activities. It contains 18 items (i.e., 13 motor and 5 cognition items), and the total score ranges from 0 to 126

The SIS 3.0 is a stroke-specific, patient-reported questionnaire for evaluating the function, participation, and health-related quality of life of stroke survivors. The SIS 3.0 has sound psychometric properties. It consists of 59 items, and higher scores indicate better function and greater participation.
