Background:Migraine is associated with autonomic symptoms. The growing body of literature suggests that the dysfunctional autonomic nervous system might play a pivotal role in the pathogenesis of migraine. Thermal therapies have been hypothesized to modulate these changes and alleviate pain. However, data regarding the efficacy of hydrotherapy in migraine remain scant. We evaluated the effect of add on hydrotherapy procedure (a hot arm and foot bath with ice massage to head) in migraine patients.Methods:Forty chronic migraine patients fulfilling the International Classification of Headache Disorders II criteria were recruited from the neurology outpatient clinic. Patients were randomized to receive either hydrotherapy plus conventional pharmacological care (n = 20) or conventional medication only (n = 20). Hydrotherapy group received treatment with hot arm and foot bath (103°F to 110°F) and ice massage to head daily for 20 min for 45 days. Patients were assessed using headache impact test (HIT), visual analog scale for pain and cardiac autonomic function by heart rate variability (HRV) before and after intervention period.Results:There was a significant decrease in HIT score, frequency, and intensity of headaches following treatment in both the groups. However, it was more evident in add on hydrotherapy group compared to pharmacological treatment alone group. There was also significant improvement in the HRV parameters. In particular, there was a significant decrease in heart rate (P = 0.017), increase in high frequency (HF) (P = 0.014) and decrease in low frequency/HF ratio (P = 0.004) in add on hydrotherapy group.Conclusion:Our study shows that add on hydrotherapy enhanced the vagal tone in addition to reducing the frequency and intensity of headaches in migraine patients.
Context and Aims:Migraine is an episodic disabling headache requiring long-term management. Migraine management through Yoga therapy would reduce the medication cost with positive health benefits. Yoga has shown to improve the quality of life, reduce the episode of headache and medication. The aim of the present study was to evaluate the efficacy of Yoga as an adjuvant therapy in migraine patients by assessing clinical outcome and autonomic functions tests.Subjects and Methods:Migraine patients were randomly given either conventional care (n = 30) or Yoga with conventional care (n = 30). Yoga group received Yoga practice session for 5 days a week for 6 weeks along with conventional care. Clinical assessment (frequency, intensity of headache and headache impact) and autonomic function test were done at baseline and at the end of the intervention.Results:Yoga with conventional care and convention care groups showed significant improvement in clinical variables, but it was better with Yoga therapy. Improvement in the vagal tone along with reduced sympathetic activity was observed in patients with migraine receiving Yoga as adjuvant therapy.Conclusions:Intervention showed significant clinical improvement in both groups. Headache frequency and intensity were reduced more in Yoga with conventional care than the conventional care group alone. Furthermore, Yoga therapy enhanced the vagal tone and decreased the sympathetic drive, hence improving the cardiac autonomic balance. Thus, Yoga therapy can be effectively incorporated as an adjuvant therapy in migraine patients.
Background The current exploratory study was aimed at estimating measures of blood pressure variability (BPV) and baroreflex sensitivity (BRS) in a healthy population in the Indian sub-continent. Methods One hundred and forty-two healthy subjects were recruited for the study. Blood pressure (BP) was recorded continuously for 15 min using the Finometer (Finapres Medical Systems, The Netherlands). For offline analysis, Nevrokard cardiovascular parameter analysis (CVPA) software (version 2.1.0) was used for BPV analysis. BRS was determined by spectral and sequence methods. One-way ANOVA and Bonferroni's test were used to compare parameters. Pearson's correlation coefficient was employed to look for possible associations between age and other continuous variables. Results Out of 196 screened volunteers, 54 were excluded and 142 subjects were grouped based on ages as 10-19 years (group 1), 20-29 years (group 2), 30-39 years (group 3), 40-49 years (group 4), and 50-59 years (group 5). Within groups, body mass index (BMI, p=0.000) and BP (systolic and diastolic) were significantly different. Post hoc analysis showed mean blood pressure (MBP) and diastolic blood pressure (DBP) differing significantly between groups 1 and 4 (p<0.05 for both) along with other cardiovascular parameters. Age correlated positively with BMI and all parameters of BP. Significant gender differences were observed for stroke volume, cardiac output, up BRS, total BRS, peripheral resistance (PR), and aortic impedance. Conclusions Our study has provided reference values for BPV and BRS in an Indian population. It also indicates age-related neurocardiac imbalance and possible utility of these tests for screening at the start of neurocardiac damage in a healthy population.
