Before you begin your actual searching, you need to find keywords and synonyms for your topic. Sometimes, articles will use other words that mean the same thing. For example, a database may use "hand grip strength" instead of "grip strength."
Before you search or if you get stuck while searching, use a thesaurus to find different words to express your ideas.
Try to find one or two good articles. "Steal" words that appear in the best articles to help you find more.
