Stroke is the leading cause of disability and the third leading cause of death worldwide, including India.

Social support group has positive effect on nursing care and health. Thus nursing staff needs to consider the patients' social support systems, including home environment, family and partners. Hence a study to assess the effectiveness of Video Assisted Teaching (VAT) regarding knowledge on, care of stroke patients among the care givers in a selected hospital, Bangalore was done . Quantitative approach was adopted for the study. Pre- experimental one group post test design was used to conduct the study in , Spandana hospitals, Bangalore. Non probability purposive sampling technique was used to select 40 care givers. A pretest with structured knowledge questionnaire was administered, followed by administration of Video Assisted Teaching (VAT)to the samples. After conducting pretest and intervention at all 3 hospitals, posttest was conducted. The mean Post-test knowledge score [38.71± 9.99] was higher than mean Pre-test knowledge score [20.26 ± 8.08]. Thus VAT is effective in improving the knowledge of caregivers on care of stroke patients.
