Systems and methods for spasticity treatment using spinal nerve magnetic stimulation
Described are methods, devices, and systems for a novel, easy to use treatment for spasticity that does not involve medication. Methods and devices herein use low-frequency repetitive magnetic fields to enhance communication in the spinal nerve, thereby allowing improved relaxation, control, and coordination in a muscle.
1. A device to treat spasticity in a subject comprising:
a. a first magnetic field generator;
b. a second magnetic field generator;
c. a power source configured to energize the first magnetic field generator and generate a repetitive pulsed magnetic field outside the subject;
d. a first mount that is configured to hold the first magnetic field generator in place; and
e. a second mount that is configured to hold the second magnetic field generator in place,
wherein the first magnetic field generator is configured to transmit repetitive magnetic field pulses to induce an electric current or voltage potential in a target location that connects a spasticity treatment location to the spine,
wherein the first mount is either a wearable vest or a chair back,
wherein the target location is on a spinal nerve ½ to 4 inches away from a spine of the subject during use of the first mount;
wherein the second magnetic field generator is configured to transmit repetitive transcranial magnetic field pulses at a frequency of a biological metric, or a harmonic or a sub-harmonic of the biological metric, the repetitive transcranial magnetic field pulses of the second magnetic field generator being delivered while also delivering the repetitive magnetic field pulses of the first magnetic field generator; and
wherein the spasticity in the subject is treated by the combination of the repetitive magnetic field pulses and the repetitive transcranial magnetic field pulses.
2. The device of claim 1 , wherein the first mount is configured to be worn on a body of the subject.
3. The device of claim 1 , wherein the first mount is configured to be held stationary.
4. The device of claim 3 , wherein the first mount is a chair back, and wherein the first mount is part of a treatment chair.
5. The device of claim 4 , wherein a position of the first mount is configured to be adjustable to move the first magnetic field generator near the target location.
6. The device of claim 4 , further comprising the second magnetic field generator as part of the treatment chair, whereby at least one of the first magnetic field generator of the treatment chair and the second magnetic field generator of the treatment chair is configured to be selected by a switch to transmit repetitive magnetic stimulation to one or more target locations.
7. The device of claim 6 , wherein the first magnetic field generator of the treatment chair and the second magnetic field generator of the treatment chair are configured to transmit repetitive magnetic stimulation to target locations concurrently.
8. The device of claim 6 , wherein the first magnetic field generator of the treatment chair and the second magnetic field generator of the treatment chair are configured to transmit repetitive magnetic stimulation to target locations non-concurrently.
9. The device of claim 1 , wherein the first magnetic field generator and the second magnetic field generator are configured to transmit repetitive magnetic stimulation respectively to the target location and transcranially concurrently.
10. The device of claim 1 , wherein the first magnetic field generator and the second magnetic field generator are configured to transmit repetitive magnetic stimulation respectively to the target location and transcranially non-concurrently.
11. The device of claim 1 , wherein the magnetic field generator is a coil.
