Article Abstract

Context: Sirshasan is supposed to increase blood flow to the brain and considered to be beneficial for intellectual function, however mastering these techniques may be difficult.

Aims: To see the effect of headstand using a tilt table on heart rate variability (HRV).

Settings And Design: A cross-sectional study that was done on 26 healthy volunteers.

Methods And Material: HRV was assessed in the supine position and 30° head tilt position for 5 min. HRV recording was done on the power lab (AD Instruments P Ltd, Castle Hill Australia). The tilt table used was Medica Podium, New Delhi, HLT-200.

Statistical Analysis Used: Paired -test.

Results: All the HRV parameters showed non-significant change except low-frequency parameters which showed significant change during head tilt.

Conclusions: Headstand to a 30° using tilt table cause a decrease in the autonomic activity which is mainly because of decrease in sympathetic activity.

Background: Early mobilization is recommended in neurocritical care, yet passive mobilization strategies for patients with impaired consciousness remain underexplored. This retrospective matched cohort study, incorporating prospectively collected intervention data, evaluates the clinical efficacy and physiological impact of passive head-up tilt positioning in patients with severe neurological injury.

Methods: We conducted a prospective-retrospective matched cohort study involving 58 patients with traumatic brain injury or hypertensive intracerebral hemorrhage.

Introduction And Importance: Postcoital syncope (PCS) is a rare, transient loss of consciousness during or after sexual intercourse, often linked to an exaggerated vagal response. The condition is poorly understood, underdiagnosed, and can significantly impact patients' quality of life and intimate relationships. Differentiating PCS from other potential causes of syncope is essential for accurate diagnosis and management.

Calf handling for spring processing represents one of the few times calves are handled in extensive production systems for the purpose of welfare and productivity interventions. The objective of this study was to identify the perspectives and preferences for common beef calf handling methods from those with experience in beef production. This study is the quantitative analysis of an online survey of 863 participants in calf handling events in western Canada.

This post hoc analysis of the "Healthy walk" study evaluated the effect of interval walking training on cardiovascular autonomic neuropathy (CAN) in type 2 diabetes (T2D) patients. At baseline, 64 T2D patients underwent tilt table testing with autonomic reflex tests: heart rate responses to the Valsalva maneuver, deep breathing, and standing, and blood pressure responses to standing and sustained handgrip, using the Ewing score. Fifty-six participants were allocated to an interval training (IT) group and control group.

Cerebral perfusion mismatch: challenging the validity of cerebral vascular resistance index in orthostatic stress.

Am J Physiol Regul Integr Comp Physiol

Institute for Energy and Environmental System, Sustainable Energy and Environmental Society Open Innovation Research Organization, Waseda University, Shinjuku-ku, Japan.

The cerebral vascular resistance index (CVRi), a single-parameter model based on systemic blood pressure rather than cerebral perfusion pressure (CPP), is widely used to assess cerebrovascular resistance. However, it does not accurately reflect the pressure-flow/velocity relationships in the cerebral circulation, as cerebral blood flow (CBF) is primarily regulated by CPP. This study evaluated the validity of CVRi during orthostatic stress induced by head-up tilt (HUT), which alters CPP independently of arterial blood pressure at the heart level and CBF.
