PubMed Background

• PubMed is a service of the U.S. National Library
  of Medicine that includes over 17 million
  citations from MEDLINE and other life science
  journals for biomedical articles back to the
  1950s. 
•  from the PubMed home page.

PubMed and MEDLINE

• MEDLINE is a subset of PubMed.
• The 1-2 million article citation difference
  includes articles that are being processed and
  will move into MEDLINE... AND articles which will
  never be included in MEDLINE (e.g., not
  biomedical or not a reliable source).

Anatomy of PubMed

• Walk through of PubMed search flow sheet
• See next slide
• PubMed
• Not intuitive
• With repetition becomes familiar
• Keys
• Use MeSH (Medical Subject Headings) where
  possible
• Search each term as you find it - It is saved in
  History 
• Items in "History" may be combined

  foreground information
•     a. Full text of article
•  
• 2. Single Citation Manager - a way to an article
  when you have limited information
•     a. Save Search, save Collection
•  
• 3. Tiger's knee
•     a. Try it on your own, ask questions!
•  
• 4. Stretching
•     a. Try it on your own, ask questions!

What if you were taking care of

• A patient with cerebral palsy.
• Begin by finding background information (what
  sources do you use?)
• Choose (print or electronic) books to find
  background information
• Next locate the latest information.
• For cutting edge use the primary literature
  (MEDLINE)

13
How to do it

• Cerebral palsy is a MeSH term.
• Narrow by using Subheading(s)
• Limits help narrow a search to a reasonable
  number of articles.
• Find the latest articles ... limit by date.
• 75 articles if limit to last two years, review
  articles, humans and English 
• Show first article...

Single Citation Matcher

• Author demonstration
• Carolee J. Winstein
• Try this with another PT faculty member
  - http//pt.usc.edu/ 
• Save search to MyNCBI Saved Searches
• Save selected articles to MyNCBI Collections

15
Tigers Knee

• Try this one on your own....
• Say you were taking care of Tiger Woods, after
  his recent anterior cruciate ligament repair. How
  would you find articles about rehabilitation
  after ACL repair?
• Ask us for help if you have questions!

16
Two Methods

• In PubMed you can type in something like
  anterior cruciate ligament rehabilitation
  (1515) or anterior cruciate ligament AND
  rehabilitation (1515)
• -- or --
• We would argue for using MeSH terms
• More precise
• MeSH 1 Anterior cruciate ligament/surgery
• MeSH 2 Physical therapy modalities/methods
• Combine with AND (209)
• Limit last English and humans (173)
• Add limits RCT, Meta Analysis, Practice guideline
  (38)
• 1st article Physical Therapy (2007), show full
  text

17
Stretching

• For a 63 year old male with low back pain, what
  duration of stretching exercises is required to
  improve hamstring muscle flexibility?
• Try to find an article to answer the question. 
• Hints Use the flow sheet as a guide, the sought
  for article is more than 5 years old.

18
Stroke Rehabilitation

• Your new patient is a 65yo RH WF.
•  
• She had an ischemic stroke a little over a year
  ago. She still has minimal use of her right upper
  extremity. Her right lower extremity has improved
  to the point that she can ambulate without
  assistive devices.
•  
• You have heard of "constraint induced movement
  therapy". You want to know more about it before
  making a treatment plan for your patient.

19
Constraint induced movement therapyfor stroke

• Ways to do it
•  
• 1. "Constraint induced movement therapy stroke"
  (154)
•     Limit humans, English, RCT, Meta
  Analysis, Guideline (31)
• 2. Concept 1 Constraint induced movement therapy
•     (Hint MeSH is "Restraint, physical")
•     Concept 2 "Stroke", with rehabilitation
  Subheading
•     Combine 1 and 2 with AND (44)
•     Limits humans, English (42)
•     Add more limits RCT, Meta Analysis,
  Guideline (14)
