Anterior Cruciate Ligament injuries on the rise globally

footballer painIn the US around 100,000-200,000 Anterior Cruciate Ligament (ACL) ruptures occur every year, although since these figures are provided by colleges and high schools in the US, they do not include injuries outside formalised sport and so the actual number may be even higher.

Here in Australia there has been a steep rise in ACL injuries over the past 15 years – a 70% hike, with a disproportionate number of these occurring in children under the age of 14.

You might think that ACL injury is more common in contact sports and caused by contact, but in fact most (~70%) occur in non-contact situations, when jumping or turning sharply. Sports that have higher rates of ACL injury include soccer, basketball, volleyball and skiing.

People’s sensitivity to magnetic fields could differ, new research shows

compassWe’ve known for some time that different people have different sensitivities to static magnetic fields.

There doesn’t appear to be an obvious reason as to who, why or where, but as a health practitioner, you place magnets on enough patients and the differences in sensitivity are obvious.

 

Back pain – a major problem

back painBack pain is incredibly common. In Australia alone around 3 million people have back problems and back pain of one description or another.

Given the total population of Australia (around 25 million) that’s over 10% of everyone in the country!

This is mirrored in many other countries – in the US for example 13% of adults surveyed in 2017 said they had back pain every day.

Magnetic field used to speed up muscle recovery

muscle injuryMagnetic fields are at the cutting edge of medical science in a number of areas. A team of researchers at the National University of Singapore have developed a device that produces an optimised magnetic field to stimulate the muscle’s energy production.

There are processes within the body that respond to what’s termed an electromagnetic efficacy window. In this particular case, the best effect for muscle recovery was achieved with a brief 10 minute exposure to a low intensity magnetic field of only 2 mT in short 6 ms bursts of magnetic pulses at 15 Hz administered within a specific time frame. See more about the therapeutic window of effectiveness in the context of magnetic fields here.

 

Why we don’t sell magnetic jewellery

jewelleryYou might be surprised to learn that in 2004, a clinical trial was published in British Medical Journal called ‘Randomised controlled trial of magnetic bracelets for relieving pain in osteoarthritis of the hip and knee’. The study concluded that…

“Pain from osteoarthritis of the hip and knee decreases when wearing magnetic bracelets. It is uncertain whether this response is due to specific or non-specific (placebo) effects.“

Some of the benefits of the magnetic bracelet were on par with front-line osteoarthritis treatments including non-steroidal topical creams and exercise therapy. However, the authors did not even suggest a mechanism for how the magnetic bracelets might have brought about this pain relief. Of course there are numerous other studies that show magnetic jewellery not providing any health benefits at all.
