Hello,
First you will want to go to libguides.brenau.edu. This is convenient place to start all of your research queries. I would choose the occupational therapy libguide listed as the number one most popular libguide under guides. Once you are in the occupational therapy libguide, choose the articles tab. Here you will find a list of the recommended databases for researching occupational therapy topics. I chose Cinahl Plus with full text to do a cursory search on your topic. Once you are in Cinahl Plus start by entering some search terms related to your topic. I chose to go to the advanced search screen and entered the terms touch techique and constant contact. My search looked like this:
Using these search terms I was able to find at least one usable article. You may find other helpful articles if you try different search terms and try different databases listed in the occupational therapy libguide. I hope this is helpful to you!
