A study was done to assess the effectiveness of warm water therapy versus contrast water therapy on joints pain among elderly patient with arthritis in selected old age home at Delhi NCR. Osteoarthritis (OA) is the most common form of arthritis, affecting nearly 30 million nation wide. A common complaint from patients is pain in the weight-bearing joints such as the hips, knees and spine as well as involvement in the finger joints.hence warm water therapy and contrast water therapy is the best method to treat arthritis. The aims of the study to assess the joint pain among elderly patient with arthritis in selected old age home at Delhi NCR. To evaluate the effectiveness of warm water therapy on joint pain among elderly patient with arthritis in selected old age home at Delhi NCR. To evaluate the effectiveness of contrast water therapy on joint pain among elderly patient with arthritis in selected old age home at Delhi NCR. To compare the effectiveness of warm water therapy versus contrast water therapy on joint pain among elderly patient with arthritis in selected old age home at Delhi NCR. To determine the association between joint pain after receiving warm water therapy with the selected demographic variable. To determine the association between joint pain after receiving contrast water therapy with the selected demographic variable. A quasi experimental- nonequivalent pretest posttest design was adopted and non probability Purposive sampling technique was used to collect the sample from 30 elderly patients with arthritis (15 for warm water therapy and 15 for contrast water therapy) at old age home. Both therapies were administered continuously for 10 days. The data was analyzed and interpreted as per objectives and the research hypothesis stated. Descriptive and inferential statistics were used for data analysis. The Results shows that there was significant difference between mean post test scores of elderly patient with arthritis in warm water therapy and contrast water therapy for joint pain score as obtained unpaired t value was higher than the tabulated value for df at 0.05 level of significance. The fishers exact test value showed that there was a significant association between post test score of elderly patient after receiving the warm water therapy and contrast water therapy with demographic variables as p value obtained is less then at 0.05 level of significance.
