“…These findings are consistent with several reports which emphasize that BPBF suppresses the hyperresponse to stress by reducing sympathetic activity [30]. For example, some researchers found that the stress-induced increases in SBP and DBP had been significantly attenuated by biofeedback-assisted relaxation treatment [31]. However, the association between the BPBF effect and sympathetic activity is inconclusive because various factors such as recognition and central nervous regulation of the cardiovascular system may be complicated [9], which makes BPBF assessment difficult.…”

Background: Although biofeedback treatment is reported to be useful for patients with mild hypertension as an adjunct to medication, it is not certain whether the presence of organ damage affects its efficacy. The aim of this study is to clarify the clinical effects of biofeedback on mild hypertension in the absence and presence of organ damage. Methods: Eleven mildly hypertensive outpatients without damage to the heart, brain, retina or kidney (4 men and 7 women), aged 40–65 years, and 11 mildly hypertensive outpatients with target organ damage and matching variables for age, sex and medication were included in this study. They underwent biofeedback treatment once a week for a total of four sessions. Results: As a result of these sessions, mean blood pressures (MBP) in the organ-damage-negative (–) group and in the organ-damage-positive (+) group were significantly reduced by 12 ± 11 and 12 ± 8, respectively. The decrease was still significant 3 months after the treatment in the organ-damage (–) group, whereas no significant change was found 1 or 3 months after the treatment in the organ-damge (+) group. Throughout these sessions, the ratio of low frequency to high frequency of heart rate variance as well as systolic and MBP gradually decreased in each group (p < 0.01); this ratio of heart rate variance was smaller, and the α-wave amplitude on the electroencephalogram was larger in the organ-damage (–) group (p < 0.05). Conclusion: These results suggested that biofeedback intervention may be effective in mild hypertension, especially when the patient is organ damage (–). Sympathetic activity seems to play an important role in the differentiated response.

The authors present a 51-year-old man with right-sided nasopharyngeal carcinoma who was treated for regional lymph node involvement by bilateral radiation therapy of the neck. Six years later he presented with episodic complaints of headache, flushing, and palpitations accompanied by elevations of blood pressure. Examination of arterial baroreflex function indicated selective afferent carotid sinus denervation. Cross spectral analysis of spontaneous heart rate and blood pressure variability showed decreased arterial baroreflex sensitivity (6.5 ms/mm Hg). Twenty-four hour measurements of blood pressure and heart rate variability showed labile hypertension during normal daytime activities. Baroreflex failure in this patient probably represents a late complication of bilateral radiation therapy of the neck.

“…The findings in our study are consistent with a previous research, which reported the beneficial effect of GSRBF on these physiological responses and stress. Paran et al (12) have reported an improvement in BP and a reduction in medication after the intervention of biofeedback-assisted relaxation training. Mogra and Singh (13) have reported lower values in systolic and diastolic BP after the intervention of yogic relaxation in combination with GSRBF training of 30 min over a period of 2 months.…”

Objective: To investigate the effectiveness of galvanic skin resistance-aided biofeedback (GSRBF) training in reducing the pulse rate, respiratory rate, and blood pressure (BP) due to perceived stress in physiotherapy students. Material and Methods: Forty-three students, those having a perceived stress scale (PSS) score of 20 or more out of 40, were subjected to GSRBF training 5 days a week for 3 weeks. The outcome measures of this study were pulse rate, respiratory rate, BP, and perceived stress. Perceived stress was assessed using PSS 10. Paired t-test was used to study the changes in dependent variables over time. Results:The reduction of the pulse rate, respiratory rate, BP, and perceived stress was found to be statistically significant at the end of the trial (p<0.001). Conclusion: The GSRBF training was found to produce a significant reduction in the physiological response and perceived stress in physiotherapy students. Further, controlled research should be conducted to verify these findings and to identify the most effective stress-reducing training protocol.
