Biomechanical footwear shows promise for knee pain
According to a neat little randomised control trial published in JAMA, wearing individualised biomechanical footwear can significantly reduce knee pain in patients with osteoarthritis. The six-month study also showed that the footwear improved the function of the knee as judged by gait studies into velocity and step length.
The researchers say, because they were only looking at results over a 24 week period, they cannot predict the long-term clinical significance of their study findings, however for a condition that is becoming more and more common as our society gets older and fatter and where our therapeutic options are relatively limited, this study might prove useful.
Importantly, this study of 220 individuals with symptomatic and radiologically-confirmed osteoarthritis included a control group. This was no mean feat (no pun intended) as the biomechanical footwear being tested involved individually adjustable, external convex pods attached to the outside of the sole of the shoe. The idea was to create a convex walking surface and balance the stress across ...
