Advice to rest in bed versus advice to stay active for acute
low-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)

Thank you.
Editor's Notes
What is data?
Whats the issue?
= fragile data format, elusive (particularly just when you need it!)
= part of research methodology & part of legacy people might want to build on your work
= how much of what you produce will you want/need to keep
Where will you record/store it?
= multiple copies, multiple places (confidential data permitting)
= Key things to consider here are:
the names you give files and folders
use of tags, or information in file properties
whether you need to conform to any conventions in your field
How will you share it?
= why should you?
Reputation
Funding
Impact
Re-use
= where? Dspace?
Use repositories and data centres
Choose open or controlled access
Consider embargoes and redactions if necessary
