More discussion on Functional Capacity Evaluations
Posted Jun 05 2012 5:31pm
Some years ago I wrote about Functional Capacity Evaluations and the lack of evidence supporting their use, particularly their use as predictive tools for establishing work “fitness”.
I’ve received some sharp criticism in the past for my stance on FCE, and I continue to look for evidence that FCE are valid and reliable. I haven’t found anything recently, and I’m still concerned that FCE are used inappropriately for people with chronic pain. There is nothing like the demand characteristics of a testing situation for a person with chronic pain to either push themselves – and have a flare-up for some days afterwards but get a “good” report suggesting they have put in “full effort” and that they can manage a full time job of a certain MET demand; or to pace themselves, using pain management strategies – and avoid a flare-up but receive a “bad” report, suggesting they haven’t put in “full effort” and despite this, they can manage a full time job of a certain MET demand.
I can’t understand why FCE providers don’t work alongside people with chronic pain and their vocational counsellors, to help them define their sustainable level of physical demand, and systematically help them to gain confidence that they can find suitable work without exacerbating their pain.
For the record, I’m not against establishing functional abilities. And I think having a systematic approach to doing this. I am against FCE’s being touted as a way to reliably determine work capacity, or to being able to determine “effort” through “consistency”. There simply isn’t published evidence to support these claims. If someone can provide me with evidence, I’ll gladly change my mind because if there is one thing scientific training teaches, it’s that it’s OK to change your mind – if there’s evidence to do so.
This doesn’t mean that FCE’s would then be fine and dandy – because, as I’ve seen far too many times – HOW they’re used goes often well beyond what any FCE can possibly do, and very often is used as a blunt instrument when some good motivational interviewing and careful vocational counselling would achieve the same.
