Introduction: Anxiety and stress are known to increase blood pressure. Psychological methods and behavioral therapy are appropriate and low-cost methods in hypertensive patients. This study aimed to assess the effect of biofeedback and biofeedback-assisted relaxation on stress and anxiety in patients with mild hypertension.Material and Methods: 10 sessions were held every other day for the intervention groups. The subjects received 15 minutes of relaxation every session. Blood pressure was recorded every session before and after relaxation. The control groups referred for 10 sessions every other day and blood pressure was recorded twice 15 minutes apart. Kettle anxiety questionnaire and Malekpour stress questionnaire were used to assess stress and anxiety, respectively.Results: Stress and anxiety scores showed significant differences in relaxation and relaxation-biofeedback method relative to the control group (p<0.05). However, the difference was not significant between relaxation and relaxation-biofeedback groups.Conclusion: Relaxation-biofeedback was effective in reducing stress and anxiety in patients with mild hypertension. However, biofeedback-relaxation did not show any significant benefit over relaxation method.

Background and purpose: Hemodialysis patients undergo high levels of psychological stress.Therefore, the present study has been conducted to determine the effect of Benson relaxation on stress among in Hemodialysis patients.Materials and methods: The present research is a two-group experimental controlled trial done in 2011, in which 40 Available Hemodialysis patients were selected from ImamKhomeini and Fatemeh Zahra Sari Educational hospital as the interventional group, and 40 Hemodialysis patients in the same hospital as the control group, and Benson relaxation training with video tape to intervention group and were performed by experimental group for 15 minute twice a day during one months, after primary training with video tape by the researcher. Data-collecting instruments included demographic information forms and a specific hemodialysis stress scale questionnaire (HSS-Baldree1982), which were evaluated before and one month after the intervention. Data were analyzed by SPSS18 statistical software using descriptive statistics, T test, Chi-square, co-variate analysis.Results: Mean stress value in case group before intervention was 64.75 ± 18.173 and after intervention was 36.2 ± 9.471. Analysis between the mean stress values of the study participants showed significant difference before and after the intervention in the case group (P<0.001). While this difference was not significant in the control group.Conclusion: Performing the low-costand simple Benson relaxation is accompanied by Improving living conditions of Hemodialysis patients, and a positive step can be taken toward Improvement and prevention of the patients' psychological problems as well as other chronic disorders through applying these practices.

Introduction: Migraine headaches are a common neurologic disorder that physicians frequently encounter in their practice. They can be disabling, leading to the individual's suffering if not treated appropriately and quickly. There is a variety of medications and treatment approaches that can be used to relieve pain. The aim of this study was to investigate the effect of progressive muscle relaxation (P.M.R), which is slowly muscle contraction and deep relaxation, on patients suffering from migraine headaches. Material and Methods: Thirty one students and staff of Semnan University of medical sciences who were affected by classic migraine participated in this study. They performed a muscle relaxation training program (M.R.T.P) for a period of 6 weeks. Total headache activity and migraine intensity during 6 weeks before MR TP and 6 weeks within the MRTP were recorded using an categorical verbal rating scale by patient. Results: The comparison of data before and after relaxation therapy showed that relaxation treatment significantly (P < 0.001) reduced total headache sum and intensity scores of total headache activity. Conclusion: The findings indicate that MR TP is an appropriate method for treatment of migraine headache without any side effects, which can be found.      

background: Infertility causes psychological and emotional tension in the couples and makes severe stress on infertile men and women. Relaxation technique is one of the methods that reduces the stress and can balance the human’s emotions. This study aimed to determine the effect of relaxation on the infertile women’s stress score.methods: This was a semi-experimental and clinical trial study. Participants randomly divided into two groups. At the beginning, the stress scores were assessed in both groups using Newton’s infertility stress questionnaire. The participants’ stress scores were evaluated and then, the relaxation technique was implemented on the intervention group. This technique was performed in twelve sessions. All the questionnaires were completed under supervision of the researcher after embryo was transferred to the uterus (after 2 weeks) and before conducting the pregnancy test.results: Independent t-test showed that the total stress score did not have a significant difference in groups before the intervention (p>0.05) whereas independent t-test indicated a significant difference in stress scores between the two groups after the intervention (p<0.05). Stress score was higher in the control group in comparison with the intervention group.conclusions: Relaxation technique can reduce the stress score in infertile women as a complementary and alternative medicine method.

Residual stress measurement is of utmost importance for the safety and reliability of engineering components and has been an active area of scientific research. Relaxation techniques such as hole drilling, slitting and ring core method are widely applied semi destructive techniques for residual stress measurements in polymer composites. This article reviews the recent literature on the measurement of residual stress in polymer composite by employing the above-mentioned relaxation techniques. This article summarizes the categories of residual stresses, causes of formation, techniques of measurements and also briefly outlines the chronological developments of the Hole drilling and slitting method. The article also provides a comparative summary of these relaxation methods.
