The impact of massage and dry cupping on dysrhythmia in cardiac patients: A randomized parallel controlled trial

Background: Heart disease is the leading cause of death in many countries around the world and is linked to numerous complications. In addition to conventional pharmacological treatments, complementary and alternative medicines like massage and dry cupping are employed to help manage the disease and its symptoms. This study aimed to compare the effects of massage and dry cupping on dysrhythmia in patients with heart diseases. Methods: This randomized parallel controlled clinical trial study was conducted in two critical care units of Shafa hospital in Kerman, southeastern Iran, in 2019-2020. A total of 90 eligible patients were allocated into three groups: massage (n = 30), dry cupping (n = 30), and control (n = 30) using a stratified block randomization method. In the massage group, the head and face were massaged for three consecutive nights, while the dry cupping group received dry cupping between the fifth cervical vertebra and the second thoracic vertebra for the same duration. Each intervention session lasted 15 min. Data collection tools included a socio-demographic and clinical characteristics questionnaire, a form for hemodynamic parameters (systolic blood pressure, diastolic blood pressure, heart rate, respiratory rate, and peripheral oxygen saturation), and a form for assessing dysrhythmia using electrocardiogram readings. Dysrhythmia in the participants was evaluated after each session. Results: The results within each group indicated a statistically significant difference in the prevalence of dysrhythmia in the dry cupping group after the intervention (P < 0.05), but this difference was not statistically significant in the massage and control groups. However, when comparing between the groups, no significant difference was found among the three groups. Additionally, there was no significant difference in the type of dysrhythmia between the groups (P > 0.05). Conclusion: While there was no difference in the type of dysrhythmia between the three groups, the additional reduction of dysrhythmia in the dry cupping group could hold clinical significance. Further studies are recommended to validate or refute the findings of the present study.
