Stroke is a medical condition that causes the cessation of blood flow to the brain cells and eventually results in cell death. It's a condition that appears out of nowhere and has long-term implications. It is a common Global health-related problem that is disabling in nature and is the second common cause of death, leading to disability in the geriatric population worldwide. Most of the stroke affects the middle cerebral arteries that's why there will be more disability of upper limb, as compared to lower limb and loss of the upper limb function, is one of the most common deficits that a person experience after stroke.

Action observation training can prime the motor system through the mirror neuron network that offers a mechanism for promoting neuroplasticity and reimbursement of motor control following stroke hemiparesis that would otherwise be restricted to use-dependent therapies.

Stroke is a medical condition that causes the cessation of blood flow to the brain cells and eventually results in cell death. It is a common Global health-related problem that is disabling in nature and is the second common cause of death, leading to disability in the geriatric population worldwide. The incidence of stroke is increasing day by day in low-income countries as compared to high-income countries because of the effects of not using evidence-based practice in health-related conditions in low-income countries. Loss of the upper limb function is one of the most common deficit that a person experience after stroke. Most of the stroke affects the middle cerebral arteries that are why there will be more disability of the upper limb as compared to the lower limb. In post-stroke patients, the affected limb develop loss of coordination and dexterity, if rehabilitation not performed effectively then can develop spasticity. Functional recovery of upper and lower limb depends on the size, site and area of the brain that is damaged post-stroke as well as the quality and type of rehabilitative intervention.

A study done in Pakistan shows that about 85% of stroke patients experience initial upper limb paresis even after 3 to 6 months. Stroke is causing motor deficits in both upper and lower limbs however evidence shows that there is only about 12% of complete functional recovery in stroke patients after a time period of 6 months while the remaining 88% of stroke patients have motor deficits in their upper limb that are disabling and are having a negative impact on their activities of daily living. Another study shows that in hemiplegic stroke patients about 30% to 66% of patients' paretic arm is still without function after 6 months post-stroke while in 5% to 20% there is the complete functional recovery of the paretic upper limb. Another study done in Italy by Stefano et al shows that about 38% of stroke patients have partial recovery in dexterity as compared to full recovery in 11.6%. More than 50% of post-stroke patients have impaired upper limb motor function. Rehabilitative interventions are more important because they can regain independence and also promote the recovery of functions that are lost. In the last few years, several approaches have been used for the recovery of hand dexterity after stroke. Among them, task-oriented therapy, robot-assisted rehabilitation and action observation have gained the greatest attention. Action observation training is one of the new developing rehabilitation technique that targets motor learning by the activation of mirror neurons and is the most important approach that targets motor and functional recovery in stroke patients. The mirror neuron system is activated during both the execution and observation of action and is the area responsible for the action observation.In inaction observation training there are actually two phases, the Observation phase and the execution phase. In the observation phase, participants are advised to observe the motor activities that are performed by a healthy individual while in the execution phase the participants are asked to practice these motor functions. In action observation training the movements are produced because of the external stimuli in which actually the visual attention recruit the cerebellar-thalamic-cortical circuit of the brain. Previous studies that were done on subacute and chronic stroke patients showed that there were positive effects of action observation training on the recovery of upper limb functions. Action observation training has a positive effect on the recovery of motor functions in stroke patients. Another study shows that action observation training in association with physical training will increase the effects of motor training in post-stroke patients. Action observation training is concerned with mirror neurons systems and they discharge mostly in association with complex tasks as compared to simple tasks.

Evidence show improvement in upper limb functional recovery, manual dexterity and upper limb activities of daily living by action observation therapy in stroke patients. However, there is not any study done on acute stroke patients. This study will be able to determine the effects of action observation therapy as compared with conventional therapy on improving upper limb motor functions like functional recovery, dexterity and everyday use of the affected upper limb in individuals with acute stroke patients.
