About The Webinar
Why are the effect sizes reported in studies of manual therapy treatment so small?
There are a number of methodological reasons why the effect sizes are predictably small; for example RCTs produce population data, and the figures included represent the average effect. As most clinicians recognise not all patients respond preferably to any one treatment. Studies will typically include patients that do well and those that don’t and when an average is taken it appears that there hasn’t been much effect (+1 and -1 =0). RCTs provide population data and tells us if an intervention works in a particular context, for some people. The challenge for clinicians is to transfer this population data to patients and determine if it works for each individual patient.
Other methodological reasons for the small effect sizes will be discussed in the webinar.
