Yoga is such a broad category, acupunture would be easier to address. Check with local chiropractors, they should have lots of handout type information.
If you are looking for a pt. oriented therapy you may want to look into acupressure. It follows all the same meridians, but doesn't use needles, so anyone can learn it and use it. A good site for a basic explanation is: http://www.garynull.com/Helpline/Org...essurelnst.htm
There is an Acupressure Institute in Berkeley, CA
Check with Borders, Barnes and Noble or Amazon
Magazine articles would be found in :
Massage and Bodywork Magazine
AMTA Journal (American Massage Therapy Journal) - Spring 2001 issue has a great article on acupressure for babies
No matter which topic you choose, there will be a ton of information available on the web. The biggest challenge will be weeding through the advertisement sites. Good luck and have fun with this assignment.
