What is it?
A necklace that contains magnets or magnetically charged beads. They are worn around the neck, either continuously or for periods throughout the day and/or night.
How does it work?
Electricity is always connected with both electrical and magnetic forces. Even though their forces are small, the main therapeutic purpose of magnets is purported to enhance bone and/or tissue healing. Human tissue contains charged molecules that may respond to the charge of magnets. When held against the skin, magnets may relax capillary walls, thereby boosting blood flow to the painful area. They may also help prevent the muscle spasms that underlie many forms of pain. It apparently achieves this by interfering with muscle contractions. Also, they may interfere with the electrochemical reactions that take place within nerve cells, impeding their ability to transmit pain messages to the brain.
Is it effective?
There is limited evidence from one study on people with chronic neck and shoulder pain that magnetic necklaces are no more effective than placebo (dummy) necklaces in reducing pain. There have been no studies of the effect of magnetic necklaces following whiplash.
Are there any disadvantages?
There has been no research on the disadvantages associated with magnetic necklaces. There is a cost associated with purchasing the necklace.
Where do you get it?
Magnetic necklaces are available via many sources including the internet, medical suppliers and pharmacies/chemists.
The use of magnetic necklaces for whiplash cannot be recommended based on the current research evidence. More research is required.
