Magneto-Vibrational Therapy for Phantom Limb Pain
This invention is a non-invasive, non-pharmaceutical device that uses magnetic fields to deliver targeted vibration therapy for the relief of phantom limb pain. Unlike existing solutions, this technology is compatible with most prosthetic sockets, allowing for pain relief without needing to remove the prosthesis.
Description
The invention uses a pair of magnets to create vibrations on the surface of the residual limb. A permanent disc magnet is placed between the prosthetic socket's liner and the inner wall. An electromagnet is then attached to the exterior of the socket, directly over the permanent magnet. A circuit board controls the electromagnet, inverting its polarity at around 100 Hz. This rapid change in polarity causes the permanent disc magnet to vibrate, providing the desired therapeutic effect. The permanent magnet is held in place by the pressure between the limb and the socket wall, and it can be attached to the socket liner either temporarily with adhesive tape or more permanently with a fabric pocket or glue. This approach avoids the technical challenges of integrating hardware directly into the socket, such as wiring and durability issues.Applications
