Try keywords such as:
Benefits, advantages, or positive
Risks, disadvantages, or negative
Impact, effect, or influence
Don't necessarily use the name of the product or program (e.g., Graston's technique)
Think about what these products or programs do, and use those keywords instead
Does that program, equipment or technique work with a certain injury?
Are they using some kind of tool (e.g., tool-assisted technique)
When searching for sources, don't necessarily use search by sport. Meaning, a sprain is a sprain and how you treat that sprain is the same regardless of sport. So, when searching don't have your sport be a search term. Save that for your write-ups.
When searching for a particular injury like an ankle sprain, don't necessarily limit to body part. Just like above, a sprain is a sprain and how you treat that sprain is the same regardless of what type of sprain it is (e.g. ankle sprain vs wrist sprain). So, when searching don't necessarily have your area of the body be a search term. Save that for your write-ups.
