What is FES?

FES or Functional electrical stimulation is a method of activating muscles affected by a central nervous system disorder such as stroke or brain injury. The device stimulates the peripheral nerves to get a contraction and assist with functional movement such as walking or reaching/grasping. The most common use of FES is to correct a drop foot; the inability to lift the toes when walking. Drop foot can be caused by both upper or lower motor neuron conditions. FES only works on upper motor neuron lesions such as stroke, MS, Cerebral Palsy and Spinal cord injuries. There are a number of devices available which supply FES. At Sense Ability Therapy we can offer assessment and treatment with Walkaide and Ness L300, as well as Ness H200 which works on increasing hand activity.

What is Walkaide?

Walkaide is a medical device which supplies FES to the lower leg muscles to assist the foot to lift during walking. The Walkaide can replace the more rigid AFO’s commonly used and allows recruitment of existing muscles which reduces atrophy and fatigue during walking. Walkaide provides the freedom to the user to walk with or without footwear, up and down stairs and even side step.

Walkaide uses sophisticated tilt sensor technology via bluetooth to analyse the movement in your leg. This is then programmed into the device and allows a smooth, well timed lift of the toes during walking.

​WalkAide is a small and easy to use device. It consists of a AA battery-operated, single-channel electrical stimulator, two electrodes, and electrode leads. WalkAide is applied directly to the leg via electrodes placed in a cuff around the leg, this can be worn discreetly under most clothing.

WalkAide needs to be set up and managed by a qualified health care professional to ensure the settings are right for you.

​​WalkAide Provides the Advantages not Found in Typical Foot Drop Treatments :

  • Easy one-handed operation and application
  • Small, self-contained unit
  • Does not require orthopedic or special shoes
  • May be worn barefoot or with slippers
  • Minimal contact means minimal discomfort with reduced perspiration
  • May improve circulation, reduce atrophy, improve voluntary control and increase joint range of motion

What is Ness L300?

The NESS L300 foot drop system is an award winning gait system which uses an Intelli-Sense Gait sensor to stimulate the appropriate muscles in your leg to improve your walking on all different surfaces. It is also wireless and is set up by the clinician to the specific settings required by you to walk efficiently and stored in the device for you to continue to use it at home. It has a slimline design which can be comfortably worn under most clothing.


What is NESS H200?

Like the above foot drop systems the NESS H200 works on hands that have been affected by upper motor neuron problems only, such as stroke. The device is an ergonomically designed, easy to operate system that allows you to experience reaching, grasping and opening/closing of the hand. It electrically stimulates the muscles of the forearm in a way tailored specifically for your needs using a wireless system that is easy to incorporate into your daily life.



Who is FES useful for?

  • Stroke
  • Cerebral Palsy
  • Incomplete spinal cord injury
  • Multiple Sclerosis
  • Brain Injury
  • Other upper motor neuron lesion conditions

Who cannot use it?

  • All lower motor neuron conditions/ peripheral nerve problems
  • People with severe fixed contractures at the ankle
  • Pacemakers – testing by cardiologist required
  • Pregnant ladies – effect not known
  • Poorly controlled epilepsy sufferers
  • People with poor skin condtion
