Functional Electrical Stimulation (FES)

Functional Electrical Stimulation (FES)-details

  • FES is a technique that utilizes patterned electrical stimulation of neural tissue with the purpose of restoring or enhancing a lost or diminished function. It produces contractions in paralysed muscles by the application of small pulses of electrical stimulation to nerves that supply the paralysed muscle. The stimulation is controlled in such a way that the movement produced provides useful function. FES is used as a tool to assist walking and also as a means of practicing various functional movements for therapeutic benefit. FES may be used to replace the natural electrical signals from the brain, helping the weak or paralyzed limbs move again. With continued stimulation over time, the brain may even be able to recapture and relearn this movement without the stimulation.

Applications of FES System:

  • a) Foot Drop

  • b) Sit to stand training

  • c) Pre-gait training

  • d) Hemiplegic gait/ circumductory gait

  • e) Shoulder subluxation

  • What is Foot Drop (Drop foot) ?
  • Foot drop ( Drop foot )is the dropping of the forefoot due to weakness, damage to the peroneal nerve or paralysis of the muscles in the anterior portion of the lower leg. It is usually a symptom of a greater problem, not a disease in itself. It is characterized by the inability or difficulty in moving the ankle and toes upward ( Dorsiflexion ).
  • The severity in foot drop can range from a temporary to permanent condition, depending on the extent of muscle weakness or paralysis. It can occur unilaterally or bilaterally. In walking, while stepping forward, the knees are slightly bent so the front of the foot can be lifted higher than usual to prevent the foot from dragging along the ground.
  • Foot drop can be caused by nerve damage alone. However, it is also caused by muscle or spinal nerve trauma, abnormal anatomy, toxins or disease. Diseases that can cause foot drop include stroke, Amyotrophic lateral sclerosis (ALS or Lou Gehrig's Disease), muscular dystrophy, Charcot Marie Tooth disease, and multiple sclerosis. As a result, walking is made:
  • (1) Less safe because of increased risk of falls
  • (2) Less efficient requiring greater energy to get anywhere
  • (3) Slower and only short distances may be possible
  • (4) Dropped foot can reduce both independence and participation in daily life.
  • (5) A dropped foot is common following many neurological conditions that affect the brain or spinal cord.


(1) Upper motor neuron injuries or conditions such as:

(2) Stroke (CVA)

(3) Cerebral Palsy (CP)

(4) Incomplete spinal cord injury

(5) Traumatic Brain Injury (TBI)

(6) familial / hereditary spastic paraparesis

Who can use FES System India?

FES System can be effective where movement has been lost due to nerve injury / disease within the brain or spinal cord. This is called an upper motor neuron lesion. If you are experiencing foot drop (drop foot), paralysis or paresis as a result of a Stroke, Multiple Sclerosis, Traumatic Brain Injury or Spinal Cord Injury, you may benefit by using FES System. The FES System is also used by clinicians as an adjunct treatment tool for Neuro rehabilitation.

What are the benefits of using FES System ?:

  • (1)Improved ground clearance:
  • (2) Reduced tripping and falls:
  • (3) Improves the position of the foot in weight bearing resulting in greater stability in stance :
  • (4) Reduced effort of walking:
  • (5) Reduced spasticity in the calf and quadriceps muscle:
  • (6) Increased walking speed:
  • (7) Heel strike with eversion:
  • (8) Reduced compensatory movements such as hip hitching or circumduction (swing the leg out sideways):
