A type of therapy. Guided imagery is basically (simplistically) using imagined images to modify emotions and physical symptoms i.e. Imaginiing a knob on the part of the body and turning it down. This technique could help with anxiety and depression from pd and decreased energy or pain. Talk to a therapist who does this.
Imagine! Guided imagery is a program of directed thoughts and suggestions that guide your imagination toward a relaxed, focused state. You can use an instructor, tapes, or scripts to help you through this process. A 2009 paper showed it can temporarily improve parkinson's tremor. It seems to be on par with relaxation techniques like music listening. Talk this over with a physical therapist.
