A Pre experimental one group pre – test and post – test study was undertaken to assess the effectiveness of Isometric Exercises on pain among Geriatrics with Arthritis at selected old age homes, Andhra Pradesh. Isometric exercise is strength training in which the joint angle and muscle length do not change during contraction. It helps to reduce joint pain by contraction, which in turn helps take strain and pressure off the joints and thus accomplishes muscle strength without moving the joint itself. 200 Geriatrics with Arthritis were selected by using Non-probability purposive sampling technique from Mathru Sri old age home and Vanaprastha old age home, Visakhapatnam. The Purposive sampling technique was used to select the sample and 100 samples were selected from each old age home for this study with the help of a modified WOMAC osteoarthritis index. Data was collected by using modified WOMAC osteoarthritis index. Isometric Exercises were administered to the identified Geriatrics with Arthritis by the investigator. After the administration of Isometric exercises, the findings revealed that there was significant difference in the pain score of geriatrics with arthritis between pre-test and post test. The mean pre-test score was reduced from 9.7 to 4.45 in the post- test. Standard deviation in pre-test and post test was 2.71 and 2.40 respectively. Since the calculated value is greater than the table value which is significant at p<0.05, the study concludes that Isometric exercises are an effective means for reduction of pain among geriatrics with arthritis.
