It is important to formulate a specific question in order to generate an effective search. PICOTT is a mnemonic used to describe the four elements of a searchable clinical question.
You are working in an out-patient clinic. Your first patient is a 56-year old woman suffering from carpal tunnel syndrome. She is experiencing numbness and swelling in her fingers and would like to know if massage therapy can help to alleviate her symptoms. What evidence can you find regarding the efficacy of massage therapy to treat carpal tunnel syndrome?
Use PICOTT to create a searchable question...
What is the efficacy of massage therapy for treating carpal tunnel syndrome?
We can use these terms to begin our search: carpal tunnel syndrome AND massage therapy.
