Stroke sometimes called as a brain attack occurs when a clot blocks the blood supply to the brain or when a blood vessel in the brain bursts. Mirror therapy reduce spasticity, muscle pain, improve muscle strength and improves patient quality of life. In which inversion of visual feedback leads to additional activation of hemisphere contralateral to the perceived limb laterally. Sample size is 60 in which 30 samples covered for experimental group, 30 samples covered for control group and Non probability purposive sampling technique used. Medical research council (MRC) scale acts as a tool for measuring the level of muscle strength. The percentage distribution of muscle strength scores reveals that stroke patients in experimental group had significant resistance whereas in control group had no resistance in the muscle strength level. The findings of the study shows the significance difference between the mean and standard deviation of post test muscle strength scores of stroke patients of experimental and control group using ‘t’ test. The obtained ‘t’ value 5.887 is greater than table value 2.05 at 29 DF in 0.05 level of significance. Therefore the obtained ‘t’ value is found to be significant.
