Question
Hello. I heard of the deerfield test for short leg, but i heard a chiropractor mention thompson deerfield test. Do you know if thats "thomsen" or "thompson"? thanks.

Answer
Dear Paula Pacilio,
Thank you for your question.
The correct spelling of this name is "Thompson."  By the way, the correct spelling for the other part of the name is "Derefield."
I hope this helps you, though I do not know the context within which you are researching this.  Perhaps, if you need any further information, you may wish to provide me with more detail about the nature of your inquiry so I may be better able to assist you.
Thanks, again!
Sincerely,
James W. Healey, DC
