Using insoles that are custom made for my feet has meant less pain, and keeps me from limping most of the time.
The conclusion of this trial is that even though "semi-rigid customized foot orthoses can improve pain and disability scores in comparison to simple insoles" that providing them is not worth the money on a Quality adjusted life year basis.
Fake money for false savings (IMO)
They conclude this despite the fact that people with rheumatoid arthritis (RA) have "greater difficulty with activities of daily living, increased fear of falling and greater self-reported foot impairment." 1
The pain and disability experienced by people with rheumatoid arthritis who have involvement of their weight bearing joints will frequently lead to damage to the ankles, knees or hips due to poor gait mechanics.
It is estimated that one in three adults with RA will fall once or more times per year (Stanmore et al, 2013a) with younger adults falling as often as older adults. Additionally 68% of people in the UK who have RA are reported to be physically inactive. In fact I have wondered for years why anyone thinks that a "Walk" is a good way to raise funds for RA.
People who have pain and disability when they walk are less able to remain in the workforce, accomplish normal chores and errands and often experience social isolation.
As a person who has been using customized orthotic insoles for over 32 years I would like to say that my experience of these insoles includes 1,664 weeks of use which is 350% more hours than the whole clinical trial which included 41 (only 29 completed the study) people for a term of 16 weeks. (464 actual person weeks of usage).
I realize that the experience of one person is not research - it is qualitative and experiential, and yet the sheer length of time people with RA must live with this pain and disability should not be so easily disregarded. My 1664 weeks provides a perspective on the length of the trial.
Through the use of custom made orthotic insoles I have been able to delay most of the surgeries I have needed for up to twenty years. I would maintain that a 16 week trial is far too short to come to conclusions about long term efficacy, and that this trial has limited exposure to experiential evidence, based on the short duration and small sample size.
Increased surgery and the future need for custom-made footwear might quickly erode the short term savings that would seem to benefit the healthcare system, while leaving patients with more pain and increased disability.
There is no sign that patients were involved in this trial in any way beyond being subjects. I would like to see some patient involvement in the outcomes that are to be measured in future research.
