IRCT20231231060580N1 IRCT 2024-06-22 Gonabad University of Medical Sciences The effect of simultaneous pressure of Shenmen ear and Neiguan points on anxiety and physiological indicators of patients with exacerbated COPD COPD The effect of simultaneous pressure of Shenmen ear and Neiguan points on anxiety and physiological indicators of patients with exacerbated COPD referred to the Emergency department 2024-07-10 anticipated 90 Complete https://irct.ir/trial/74738 interventional Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Supportive, Randomization description: Randomization method and description of each method: simple randomization, permutation blocks Sampling will be done in an available manner and based on the entry criteria. Then they will be randomly assigned to sham and intervention groups using four permutation blocks (AABB, ABAB, ABBA, BABA, BAAB, BBAA) by throwing a dice. In this way, we give codes 1 to 6 to each quadruple permutation block to match the numbers in the dice. We give AABB code 1, ABAB block code 2, ABBA block code 3, BABA block code 4, BBAA block code 5, and BAAB block code 6. Then, because the required sample size for this research is 90 people, we have to throw the dice 23 times (4*12=48) so that at least 90 samples are included in the study, and after matching the number of the dice with the code belonging to the replacement blocks, We line up the order of samples one after the other. In this method, the letters A mean the samples placed in the intervention group, and the letters B mean the samples placed in the sham group, Blinding description: This study is double-blind in that the samples and the researcher who evaluates the level of anxiety and physiological indicators will not know about the allocation of the samples in the intervention and sham groups. N/A Anxiety of patients with chronic obstructive pulmonary disease. Intervention group: Intervention group: gentle and simultaneous pressure will be applied on the sand point of the ear and the Nigwan point of the non-dominant hand with an average of 20-25 cycles per minute and counter-clockwise for 10 minutes and only once. sham group: acupressure on false points, which will include the beginning of the ear cavity on the non-dominant side and 2.5 cm below the nigoan point of the non-dominant hand (toward the arm); will be applied..
