Study Summary
The aim of this study is to investigate brain response and connectivity changes evoked by video-guided acupuncture imagery treatment (VGAIT) and verum and sham acupuncture in knee osteoarthritis patients to elucidate the underlying brain mechanisms of mind-body interaction, imagery, and acupuncture.
Primary Outcome
fMRI measures changes in brain activity by detecting fluctuations in blood oxygenation levels. The primary signal used in fMRI is the Blood Oxygen Level Dependent (BOLD) signal, which reflects neuronal activity indirectly through hemodynamic responses.
Interventions
