Introduction: Stroke is one of the main causes of permanent disability and more than two thirds of survivors develop spasticity. Due to the complexity of the interventions for upper limb spasticity, at the moment there is a lack of evidence regarding innovative and effective rehabilitative interventions. Action Observation Rehabilitation Training constitutes a promising rehabilitative method to improve upper limb muscle spasticity on stroke patients

Objective: To find out the Effect of Action Observation Rehabilitation Training on upper limb muscle spasticity in stroke patients admitted in tertiary care hospital, Trivandrum.

Methods: Quasi Experimental research design was used for the study.30 stroke patients who met inclusion criteria were selected using convenient sampling technique and allotted to both experimental(n=30) and control group(n=30). Modified Ash Worth Scale was used to measure the spasticity. Action Observation Rehabilitation Training therapy was given to the experimental group daily for 30 minutes for 6 days for 6 weeks in addition to conventional rehabilitative treatment whereas control group received only conventional rehabilitative treatment. Post intervention measurement was done after 6 weeks of treatment.
