It is important to speak with a health provider about using FES to make sure it is safe and suitable for you and to learn how to use the equipment correctly.
FES is usually applied through electrodes that are placed on the surface of the skin, although electrodes can also be implanted into the muscles. Electrodes are placed over nerves or part of the muscles below the SCI that respond well to electrical stimulation. The electrodes are then attached to an adjustable machine that generates the stimulation. Your health provider will determine the settings that are used for the treatment and how long it will last.
The electrical stimulation is then gradually turned up until the muscles begin to tense or contract. Depending on your sensation, as the machine is turned up, you may feel pins and needles or other unusual sensations, which may take some time to get used to. The aim is to create a forceful but tolerable muscle contraction.
FES is applied through electrodes on the leg muscles during assisted walking.2
If the electrical stimulation goes well, it is then combined with a movement task. This may be as simple as lifting a wrist or ankle or more complex such as cycling on a stationary bike, rowing on a rowing machine, grasping, or stepping in parallel bars or a body weight support treadmill system.
The length of each session will vary depending on the goals of the treatment. Time may be required to enable your muscles to tolerate longer sessions as the muscles may fatigue quickly. Sessions are usually done several times per week for several weeks to gain training benefits.
Your health provider will monitor your response to the treatment and inspect the skin for any redness or irritation after the treatment has ended. Once you have learned to use FES safely, you may be able to use it on your own.
