QiGong meditation practice shows reproducible changes in brain function, including blood flow and electrical activity, in trained practitioners. Neuromonitoring tools objectively measure these cerebral modulations during the ancient Chinese exercise.

Area of Science:

  • Neuroscience
  • Integrative and Complementary Medicine
  • Psychophysiology

Background:

  • QiGong is an ancient Chinese mind-body exercise with reported health benefits.
  • Modern neuromonitoring techniques offer objective methods to study brain function.
  • Understanding the neurophysiological effects of QiGong can validate its practice.

Purpose of the Study:

  • To investigate the effects of QiGong on brain function using multimodal neuromonitoring.
  • To objectify the cerebral modulations associated with QiGong practice.

Main Methods:

  • Utilized transcranial Doppler sonography (TCD), electroencephalography (EEG), and near-infrared spectroscopy (NIRS).
  • Monitored brain activity and cerebral blood flow in two subjects, including a QiGong master.

Related Experiment Videos

  • Applied multimodal and imagined stimuli during QiGong practice.

    • Main Results:

    • Reproducible changes in TCD, EEG, and NIRS findings were observed during QiGong.
    • Significant alterations in cerebral blood flow velocity (vm) were recorded (e.g., +22.2% posterior cerebral artery, -23.1% middle cerebral artery).
    • Similar neurophysiological effects were noted in both subjects, suggesting generalizability.

    Conclusions:

    • Neuromonitoring can objectively measure and validate the cerebral modulations induced by QiGong.
    • QiGong practice leads to measurable changes in brain function and hemodynamics.
    • This study provides objective evidence for the neurophysiological impact of QiGong.
