Lecture 2 Flashcards
What is background
- Understands the nature of the problem
- Focuses on medical aspects
- Asked by students/new grads
- Experienced PT’s will ask questions
What is foreground
- Central to EBPT
- Can involve tests, clinical measures, interventions and clinical predications
Involves PICO
What is EBP
Integration of:
1. Best evidence
2. Patient values
3. Clinical expertise
What are the 5 steps of EBP (5 A’s)
- Ask - question
- Access - evidence
- Appraise - validate
- Apply - results to patient
- Assess - evaluate the effectiveness
What is the best search engine
Cochrane library

How do we use Boolean operators
OR is for similar terms
AND is for intervention/disorder
AND - indicates both terms are present
OR - indicate either term may be present
Does “AND” increase or decrease your search results
