A Podiatrist's View On Running Shoe Selection

Ever wondered what an evidence-based Sports Podiatrist's views are on choosing your next running shoes? This is what Ian Griffins on Ransacker.com wrote.

Mr Griffins did an excellent job on saying what many current heath professionals are still doing now with regards to running shoe selection is flawed. He also discusses how the method of assessing your foot type by your wet foot print came about (and why the wet foot test is "nonsense" to quote him), why controlling pronation  is a poor way of choosing a shoe, why aligning runners to the same neutral position makes no sense.

Please have a look if you want to read his post http://www.ransacker.co.uk/running-shoes/goings-on/what-running-shoes-should-you-wear-the-myths-busted/.

I've written on running shoes before, have a look here http://weloverunning.blogspot.com/2010/08/do-your-running-shoes-prevent-injuries.html and http://weloverunning.blogspot.com/2009/03/do-high-tech-running-shoes-work.html.

Acupuncture For Chronic Low Back Pain

Acupuncture is astrological in origin and not evidence-based so writes the author in a review article in yesterday's Straits Times (page A32, 120211). How is it linked to astrology?  There is "qi" flowing in the human body's loop of meridians interlinking 361 points on the skin. Since the qi flows in a closed loop, you can insert needles at any point away from the painful site to relieve pain if done well.

Why 361 points? The earth takes just three minutes under 24 hours to rotate 360 degrees on its axis while the sun appears to revolve 361 degrees every 24 hours. Hence the link to astrology.

Previously I have read both articles from the Spine Journal and New England Journal of Medicine quoted by the author in which acupuncture was researched to see its efficacy on low back pain. The conclusion from the systematic review (the highest level in research) was that both real and sham acupuncture were more effective than no treatment.  It added that acupuncture may be used as a supplement to other forms of conventional therapy for low back pain.

So here's the deal, real acupuncture does no better than sham acupuncture. It probably is the placebo effect working when patients feel better.
