FES was originally designed and is still most commonly used to support those who suffer from drop foot. Drop foot occurs when the dorsiflexor muscles do not work correct thus causing your foot to remain dropped throughout walking. This can cause difficulty with walking as you are more likely to scuff your toes and foot on the ground consequently increasing the risk of falls.
To combat drop foot electrodes are placed upon the common peroneal nerve and small electrical impulses are sent this causes the nerve to respond and the muscle to contract appropriately. To time the impulses correctly the user wears a heel switch which is pressure sensitive, impulses are sent as the heel lifts off the floor and ends when the heel strikes the floor. This enables the user to walk in a more natural fluid walking pattern.
Drop foot or dorsal flexor weakness can be caused by a variety of conditions and FES can be used for many of them including:
This list of conditions is not exhaustive. If you are unsure if you would be suitable for a FES device please contact us to discuss.
There are many benefits that come from using a FES device. These include:

There are a variety of devices that may be used including:
MyGait is a wireless FES device from Ottobock. The MyGait comprises of a cuff (available in two styles; soft and original), a heel switch and a remote control. The remote control enables users to adjust to different modes as well as the intensity of the stimulation impulse. The MyGait is a two channel device enabling one channel to provide stimulation to the dorsiflexor muscles and the other to be used to target a secondary muscle group.
The ODFS Pace from Odstock Medical Ltd is a wired device which comprises of a small digital device which provides the stimulation impulse, electrodes which are placed upon the skin and a footswitch to be worn underneath the heel. These components are connected via a series of wires. A wireless variation of the Pace is also available from Odstock Medical Ltd.
The Bioness L300 is a wireless FES device available in two sizes (standard and small for paediatric users). The device uses a lightweight stimulation cuff which contains the electrodes which is worn just under the knee, a gait sensor which attaches to your shoe and a portable control unit allowing you to adjust the level of stimulation.
The process to receive a FES device for drop foot would be:
You will initially need to be assessed to decide whether you are suitable for functional electrical stimulation. If it is found that your muscles and nerves respond well to the stimulation then your orthotist recommend the appropriate device for your requirements. Once selected your orthotist will advise you on how to correctly wear the device as well as appropriate treatment plan. They will adjust the device to ensure the signals sent are suitable for your needs.
