Isla Kuhn

• how to clarify the question(s) on which you need to find literature

• selecting the databases and other resources you will need to search

• devising the most comprehensive literature search strategy so you know you’ve not missed any relevant studies

• keeping up to date with new information appearing between the initial search and write-up

• issues around management of process and results • management of references (using software such as

RefMan), and getting hold of the full text article

CAMBRIDGE UNIVERSITY LIBRARYMEDICAL LIBRARYBoolean Logic

AND – to narrow the search by combining different topics

eg

“physiotherapy” and “stroke”

Both terms must be present in the results.

StrokePhysiotherapy


OR – to broaden your search, by combining similar terms

eg

“exercise” or “physical activity”

Either term can be present in the resulting set of articles.

Physical activityExercise


NOT – to restrict your search so that it does not contain a particular term

eg

“physical therapy” not “manual therapy”

The first, but not the second, term must be present.

Manual Therapy

Physical Therapy

Advice to rest in bed versus advice to stay active for acutelow-back pain and sciatica

The objective of this review is to determine the effects of advice to rest in bed or stay active for patients with acute low-back pain or sciatica.

The following comparisons will be made:

• Bed rest versus staying active

• Bed rest versus other treatments (besides staying active)

• Shorter periods of bed rest versus longer periods of bed rest

• Staying active versus other treatments (besides bed rest)

• Comparison between different forms of advice to stay active (e.g. avoiding bedrest, staying active)

articles )

• Don’t imagine that your first attempt will get all the articles you need

• Don’t give up!
