Basset et al started to study electromangnetic fields in year 1962, and noticed helpful effect to bone healing. Later on, this has not been confirmed in later studies. The same seems to be also in magnetic therapy studies. We have also studied the effect of low-density US for fracture healing, and noticed not at all the effect for bone healing (Lauri Handolin et al). Until yet, we dont know any method to accelerate bone healing in fractures.
Shock wave therapy is a method that helps healing in cases of delayed union or not union. The first authors to apply this method were Valchanov and Mihailov in the 70's.
Anything increasing vascularization at the site of lesion will increase healing activities and access to our adult stem cells which can differentiate into the needed tissues for healing. So, from that and possibly other vantage points, magnet therapy should definitely aid in the healing process.
Max, what about the presence of metal implant at the site of lesion and the effect of magnet therapy ? In my opinon the magnet therapy could have a negative effect if the implants have ferro-magnetic properties. Of course, most of the implants used today are made of technically pure titanium or titanium alloys. But the problem is not solved definitely.
Yes, Panayot, if there are metal implants with ferro-magnetic properties, I would suspect potential issues to consider. But then I have to consider my own multichannel cochlear implant which is held in place by a magent on the outside and inside and that area where the external magnet attaches I have a white spot of hair the size and shape of the magnet itself. Possibly, the effect of having a positive electron rotation in the metal and/or magnet and having a negative electron rotation of the human cells may present even more considerations. But over all, all factors being equal, if there is not implant metal prostheses near the site of lesion, my feeling and anecdotal observations are that healing at the site of a bone fracture is more likely to heal faster with the magnet.
Pulsed Magnetic Fields generated in very low frequency & amplitude has been found to have anti inflammatory effects , heals injured tissues & gives pain relief . The greatest benefit has been in fracture healing . It is also valuable in healing ulcers ( Diabetic , pressure , venous ) , Osteoarthritis of knee & spine , Sports injury , post operative pain relief & rapid healing of tissues in plastic surgery & various neurological diseases ( Parkinson's disease , multiple sclerosis , migraine , painful neuropathy & depression ) . It is the magnetic fields generated by electricity , which is pulsed & the three components of low amplitude , low frequency & type of wave ( sine , square , saw tooth ) which is essential for its benefits , as they are able to penetrate deep into the tissues , which is not possible by magnets alone . FDA has approved it for treatment of non healing fractures .
Dear Dr. Shivakumar,
Your posting has a valuable sense.
Could you please direct me to some articles published in scientific periodicals or papers on your personal experience? Thank you for your efforts in advance.
Dear Panayot Tanchev,
I have placed my article under dataset on our experience with Pulsed Magnetic Field therapy in Chennai , which you could view under my contributions in RG . The references we have cited will be useful to you . Thanks for your interest .
Our experience has revealed that Extremely Low Frequency ( 1 - 10 Hz ) & low amplitude ( 1500 nano Tesla ) along with Sine / Square wave was adequate for eliciting very good biological response in various tissues . This was one of the major contribution of our Institute . This has been our protocol to treat various diseases . There was good therapeutic effects on Osteoarthritis of knee & spine , Polyarthritis ( Rheumatoid & Sero - negative ) , fracture healing , Lepritic & Diabetic ulcers .
