Positron emission tomography (PET) is a three-dimensional diagnostic imaging technology in nuclear medicine measuring physiological function by looking at various functions of the body.
Positron Emission Tomography (PET) is a 3D imaging technique of wide application, which measures physiological function by looking at blood flow, metabolism, neurotransmitters, and radio-labelled drugs [ 17].
Firstly, we quantified the specific growth rate as an overall measure of physiological function.
The secondary outcomes will be measures of physiological function including aerobic capacity, muscle strength, and balance.
This tool has been validated and includes five valid and reliable measures of physiological functioning – visual contrast sensitivity, lower limb proprioception, quadriceps strength, reaction time and postural sway.
However, little evidence to support other measures such as physiological functions is available.
Mr Williams argues that rather than "helping someone get by with lying", his techniques merely teach people "how to control the physiological functions measured by the polygraph", thereby exposing and exploiting a fundamental weakness of the test.
Biofeedback refers to the use of electronic or electromechanical tools to measure and then feed back information about physiological functions and it is useful in paediatric headache to understanding and addressing the mind-body connection [22, 74].
As a starting point, our laboratory performed an experiment designed to measure physiological response of healthy adult dogs as a function of age and diet [4].
These measures were chosen based on the rationale that physiological functions such as vision, proprioception, strength, reaction time, and postural stability are significantly associated with falls risk [ 18- 20].
