Electrical Stimulation, how it works
Electrical stimulation, sometimes referred to as e-stim, can be an effective tool in reducing the symptoms of stroke, such as joint pain, and in increasing functionality. Is it a good option for you?
How it Works
Your body runs on electrical pulses. When you want to perform a task, your brain sends an electric pulse to the proper muscles, directing them to contract. A stroke can interfere with that process, though, if the part of your brain responsible for an action is destroyed. The neural connection no longer exists.
E-stim provides the initiating electrical pulse when the brain cannot. Usually delivered via electrodes applied to the skin, the pulse can be set at regular intervals, be triggered manually, or build on weak signals from the brain. In addition to skin electrodes, the pulse can be delivered in conjunction with a prosthetic or implanted device.
It Can Improve Movement
To regain function, the brain must “rewire” by forming new neural connections that will send the necessary electrical pulses to your muscles. E-stim aids in that process by helping you make desired movements. As the muscles strengthen and neural connections form, theoretically, you would be able to make more of the movement on your own.
For best results, e-stim should be used on a regular basis in conjunction with therapy and/or a home exercise program.
It Can Help Manage Spasticity
E-stim can also be effective reducing spasticity and relieving associated pain by exercising and “training” the muscles. Although it could take up to three months to see results, you may experience an increased range of motion and even discover that you have more voluntary muscle control, or movement, than you thought you did.
Unfortunately, if you stop using the e-stim, spasticity will usually return.
Other Applications
Research has shown e-stim can be used to:
• Increase range of motion
• Reduce subluxation, or dislocating, of the shoulder
• Heal pressure sores
• Stabilize the hip, knee, and ankle
• Assist with walking
• Strengthen muscles
• Improve swallowing
What it Costs
A basic e-stim unit, such as the Empi 300pv, lists at approximately $350, the equivalent of one or two therapy sessions, with prices ranging into the thousands for more elaborate options.
Before purchasing a unit on your own, consult your doctor about how e-stim might apply to your unique symptoms. After purchase, visit a rehabilitation therapist to learn how to properly use the unit for best results.
