Unfortunately research into complementary therapies has been rather limited and more funding is required. Some therapists will point to research into their particular discipline, and whilst it may have been properly conducted, it is important to note that the definition of ‘research’ can vary and not all of it is validated scientifically. As such, statements regarding research should be treated with caution.
For more information on completed research and standards of research see the Parkinson’s Disease Society booklet "Complementary Therapies and Parkinson’s disease".1 This also contains information on the various therapies available, how to find a reputable therapist and anecdotal accounts from people with Parkinson’s.
Guidance on research into complementary therapies in general is also available on the website of The Research Council for Complementary Medicine.2
