Useful machines for relieving back pain include inversion tables, according to Mayo Clinic, and nerve stimulation machines, states WebMD. There is also an injectable Stimwave Freedom Spinal Cord Stimulation system that helps with back and leg pain that is approved by the Food and Drug Administration.
Back inversion tables take the pressure of gravity off the spine, increasing the amount of space between the vertebrae, states Mayo Clinic. This only relieves back pain temporarily and is not intended for people with high blood pressure, heart disease and glaucoma because the heartbeat slows, and blood fills the eyes.
With electric nerve stimulation, electrical pulses are sent to the nerves and spinal cord to ease the nerve pulses that cause pain, states WebMD. The injectable Stimwave Freedom Spinal Cord Stimulation system provides the same relief as traditional electronic impulse machines without the need for wires, toxic materials or batteries.
