All treatments are given to the lying position.Results: there are significant relaxation exercises to decrease DNI p = 0.001 (p <0.05), there is no influence to listen to music on the decline DNI, p = 0.560 (p> 0.05). Providing relaxation exercises more influence on the decline compared to listening to music DNI p = 0.027 (p <0.05).conclusion: there is a significant difference between the effect of relaxation exercises with listening to the decline of the DNI. Relaxation exercises better than listening to the decline of the DNI.]]>
