Quasi Experimental research design was used.60 Elderly were selected by Non-Probability Purposive sampling technique. Modified KOOS pain assessment Scale was used to assess the level of knee pain. The data were analyzed and interpreted in light of objectives and hypotheses. The descriptive and inferential statistics in term of mean, standard deviation, t test and chi square were used for analysis of data. The mean difference in Experimental group was 11.4 and Control group was 0.08. It reveals that mean difference in experimental group significantly higher than control group. In experimental group the calculated paired ‘t’ value of level of knee pain was greater than tabulated value at 0.05 level of significance. In control group the calculated paired ‘t’ value of level of knee pain was lower than tabulated value at 0.05 level of significance. There was significant difference in paired calculated ‘t’ test value in experimental and control group. In comparison of post-test values of level of knee pain between experimental group, calculated ‘t’ value was significantly higher than tabulated ‘t’ value at 0.05 level of significance. Chi square test was used to find out association between Mean post test score and selected demographic variable. The finding reveals that, there was significant association between level of knee pain with Previous occupation. Application of mustard plaster found to be effective intervention in reducing knee pain among Elderly. The findings of the study enlighten the fact that mustard plaster can be used as a cost-effective nursing intervention in reducing level of knee pain.
