The purpose of this study was to examine cerebral autoregulation (CA) in young athletes
experiencing concussion. The subjects were monitored and repeatedly tested 72 hours, 2 …

Sport-related concussion is known to affect a variety of brain functions. However, the impact
of this brain injury on cerebral autoregulation (CA) is poorly understood. Thus, the goal of …

Various methodologies to assess cerebral autoregulation (CA) have been developed,
including model-based methods (eg autoregulation index, ARI), correlation coefficient …

Objective Examine how the frequency-dependent relationship between blood pressure (BP)
and cerebral blood velocity (CBV) is affected by acute sport-related concussion. Design …

Purpose We investigated the effect of handgrip (HG) maneuver on time-varying estimates of
dynamic cerebral autoregulation (CA) using the autoregressive moving average technique …

Short-term regulation of cerebral blood flow (CBF) is controlled by myogenic, metabolic and
neurogenic mechanisms, which maintain flow within narrow limits, despite large changes in …

Objective: To examine early cerebral haemodynamic changes among youth hospitalized
with sports-related traumatic brain injury (TBI). Study design: Youth 0–18 years admitted to a …

Aerobic fitness may be associated with reduced orthostatic tolerance. To investigate whether
trained individuals have less effective regulation of cerebral vascular resistance, we studied …

Objective Classic methods for assessing cerebral autoregulation involve a transfer function
analysis performed using the Fourier transform to quantify relationship between fluctuations …

Cerebral autoregulation (CA) mechanisms maintain blood flow approximately stable despite
changes in arterial blood pressure. Mathematical models that characterise this system have …
