Peripheral magnetic stimulation is a non-invasive technique that delivers a rapid pulsed magnetic field to the skin. It can be used to treat a wide range of pain and movement problems, including muscle weakness. It's a relatively new approach to treating chronic pain conditions, but many patients who experience relief after permanent placement of a peripheral nerve stimulator report significant improvement.
To determine if you are a candidate for PNS, Piedmont Interventional Spine & Pain Center offers a trial period where you can try the device for 3-5 days to see if it's effective in reducing your pain and improving your function. If you don't find relief with the temporary electrode, your provider will recommend a more permanent device.
The procedure involves placing a small coil (MicroLead) near a nerve. Your physician will use an x-ray machine to help guide the MicroLead to the correct area, and then she will attach an external battery to it. A numbing medication may also be given.
During the procedure, you will remain still and be placed under general anesthesia. You will be asked to avoid foods and drinks prior to the procedure, and you should stop taking any medications. You will need to arrange for someone to drive you home after the procedure.
If you're a good candidate for PNS, your provider will administer an injection of local anesthesia in the treatment area. This will prevent discomfort and allow you to relax during the procedure.
After the local anesthetic, Peripheral magnetic stimulation your physician will place a MicroLead near a nerve. An external battery will be attached to the MicroLead, and a hollow needle called an introducer will be placed in the nerve. Your physician will then connect the MicroLead to the battery, and the device will be turned on.
Your doctor will ask you to lie down flat on your back. Using an x-ray machine, she will guide the MicroLead to the nerve and then insert it into the target site. She will then turn the device on and will ask you to provide feedback on how to best position the MicroLead for the most effective results.
When your electrode is in position, you will be asked to hold your arm up. This will help your physician identify the target site for the MicroLead and ensure that you are comfortable.
The physician then places the MicroLead in your ulnar nerve, a large nerve that runs through your ring finger and thumb. This is the most common site for placement. Once your MicroLead is positioned in your ulnar nerve, the physician will then connect it to an external battery.
During the procedure, your physician will use an x-ray machine, to help her place the MicroLead in your ulnar neurovascular complex. Your doctor will then turn the device on and will ask for your feedback on how to best position the MicroLead.
Once your physician has found the most effective location for the MicroLead, you will be placed under general anesthesia. The MicroLead will be connected to the battery, and a hollow needle called an introducer is placed in your ulnar nerve. You will then be asked to hold your arm up. This may be uncomfortable, but it's important to stay still for the procedure.
