Hi, welcome to Back Pain:
Are we Measuring
the Right Things?
A talk in the series
"Current Thinking
in Back Pain Management."
I'm Robert Froud.
I originally trained
as a manual therapist
before going to read
medical statistics
and epidemiology.
I split my time between
the Norwegian School
of Health Sciences in Oslo,
and Warwick Medical School
in the UK.

So here's just
a running order of the topics
I'm going
to cover in this talk.
First of all I'm gonna do
a very brief review
of things we looked at
in the previous talk entitled
"How do we currently
measure back pain?"
It's not necessary to have
seen that previous talk
to understand
or to follow this talk.
I'm going to explore
what's important to patients,
what they value
in terms of improvement
in their back pain.
Then I'm gonna look at
some of the issues
with their current
outcome measures
and things we measure,
before going on to consider
how we might improve
outcome measurement
more generally.

So in the previous talk
we saw the most common
outcome measures
that are used
in back pain trials.
We saw that
the visual analogue scale
for pain is very commonly used,
as is the Roland Morris
Disability Questionnaire,
and Oswestry
Disability Questionnaire,
and also the numerical
rating scale for pain.
We reviewed some
of the ideal properties
of these instruments.
We looked at
some of the thinking
that goes into
making an instrument,
and then how we ensure
that it does what
we need it to do.
And primarily that is
to remain stable
when there is no change
in the health
domain of interest
and to actually detect changes
when there are
important changes over time.
