There are several ways to get help with your research!
Concept maps are a tool to help you:
Ask yourself: what do I already know about my topic? what am I curious about? what kind of data do I need, and where am I likely to find that data? Creating a map of these subtopics that will help you flesh out your topic. Keep in mind that this map may include as many questions as it does ideas...after all, you haven't researched your topic yet! Also remember that you are not expected to address all of the subtopics in your work, nor would it be wise for you to try. You will likely focus on just one or two areas of your map for your final research.
The process is simple: start with your big, broad topic in the middle of your page. It can be a population, a bodily system, an injury, a type of rehabilitation, an element of biomechanics, etc.
