The NESS® L300 is an advanced neuroprosthesis designed to enable a more natural gait and a return to a more normal lifestyle.  It is a breakthrough intended for treating foot drop associated with a number of conditions, including stroke, traumatic brain injury, multiple sclerosis, cerebral palsy and incomplete spinal cord injury.  In addition to facilitating a more normal gait, the NESS L300 may also be used for muscle reeducation, to prevent/retard disuse atrophy, to maintain or increase joint range of motion and to increase blood flow.

The NESS L300™ is intended to raise the foot up in individuals with foot drop.  During the swing phase of walking, the NESS L300™ electrically stimulates muscles in the affected leg to provide upward movement of the foot and prevent drag in walking.  It may also facilitate muscle re-education, prevent/retard disuse atrophy (weakness from disuse), maintain or increase joint range of motion and increase local blood flow. 

England Physical Therapy is the ONLY physical therapy practice in Orange County trained in the use of the NESS® L300™, a revolution in Functional Electrical Stimulation (FES) technology that can help patients with life-altering neurological disorders regain lost mobility and recapture their independence.  Central nervous system injuries often result in foot drop—leading to instability and increased effort during gait.

Sonya Huizar Smith, PT, DPT has extensive experience evaluating and fitting patients with the NESS L300 as well as Teresa England, PT, MPT also being uniquely qualified to fit patients with this advanced technology as it demands expertise in normal and pathological gait.  Teresa England, PT, MPT has taught Observational Gait Analysis internationally, nationally and in university settings for 20 years and is a recognized expert in the field.

Third, are you able to walk?

Ability to walk with or without a walker or cane either around the house and / or in the community.

Not walking, confined to a wheelchair.**


Require more than minimal assistance from one person to stand or walk.**

**Individuals requiring greater than minimal assistance, or that have issues interfering with their walking beyond just foot drop, are encouraged to schedule a physical therapy evaluation for the purpose of determining if skilled physical therapy would be beneficial in increasing their function and quality of life. 

Explanation for Inappropriate Diagnoses

Typically people with actual damage to the nerve do not benefit from the NESS L300.  The NESS L300 works by stimulating the nerve that goes to the muscle that picks up the foot.  If the nerve is damaged, there is no way to send the message to the muscle.  That’s why problems that involve signals from the brain--like stroke, Parkinson’s disease and brain injuries benefit, and conditions that involve actual nerve damage (like diabetic neuropathies, nerve crush injuries, complete spinal cord injuries) don’t.

The familiar analogy of a telephone is useful to aid understanding of how the brain, nerves and muscles interact.  In this analogy, the telephone is like the brain, the telephone line is the nerve and the receiver is the muscle that picks the foot up.  Much like you could not get a message through a phone line when the line is cut, you cannot signal the muscle without a working nerve.



When the problem is the signal being sent, the NESS L300™ works to time the signal. When there is no line (in our analogy the line = nerve) connecting the phone to the receiver, there is nothing to transmit the signal.
