Q. What is Functional Electrical Stimulation (FES)?
A. FES is the use of low-level electrical stimulation to restore or improve function due to a neurological condition or injury. FES is designed to produce movements or functions that mimic natural voluntary movements to help you lead a more natural life.
Q. How does FES create body movement?
A. The brain sends electrical signals to your body through the nervous system. These signals tell the body how to move. When injury or disease interrupts normal communication between the brain and lower extremities, muscle weakness or paralysis may result. If a muscle and its nerve supply remain healthy, but communication from the brain cannot occur because of a problem with the central nervous system, 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.
Q. What are the benefits of FES when applied to paralysis or paresis (partial loss of movement)?
A. FES may improve voluntary movement in injured limbs. It may also reeducate your muscles, prevent muscle loss (often called atrophy), maintain or increase joint range of motion and increase local blood flow.
Q. Who is a candidate for FES?
A. If you are experiencing paralysis or paresis as a result of a Stroke, Multiple Sclerosis, Traumatic Brain Injury or Spinal Cord Injury, you may be a candidate. You should consult with your physician or clinician to find out if FES is the right treatment for you. A number of factors impact the overall benefit a person will receive from using FES, including the severity and nature of the paralysis, the length of time since the paralysis occurred and how frequently the system is used.
Q. Does FES hurt?
A. FES is not supposed to hurt. Most people describe FES as a tingling sensation. The initial step is for your therapist to find the appropriate level of stimulation needed, followed by a gradual buildup of intensity over time. Note: There are a number of issues affecting an individual’s tolerance of FES, including electrode size and position, the type of pulse that is administered, the muscle group stimulated, and the intensity of the stimulation. The large electrodes and customized fit of the L300 Foot Drop System help to minimize any uncomfortable sensation the stimulation may create.
Q. When is it appropriate to start using FES?
A. Before beginning any kind of rehabilitation therapy, it is essential to speak with your physician. In most cases, use of FES can be started almost immediately following your initial injury. Clinical studies show that early use of FES may provide optimal benefits of functional recovery. However, even those patients whose injuries occurred more than a year before starting rehabilitation demonstrated significant improvements.1
Q. How long will someone benefit from using FES?
A. Your doctor and clinician can help you determine the length of time you will use FES.


Q. What is the L300 Foot Drop System?
A. The L300 Foot Drop System is a state-of-the-art Functional Electrical Stimulation (FES) system that uses mild stimulation of nerves and muscles to help people with foot drop regain a more natural walking pattern (gait).
Q. How does the L300 Foot Drop System work?
A. The L300 Foot Drop System has three main parts that use wireless communication to "talk" to each other. Watch the video to see how the L300 Foot Drop System works.
Q. What sizes does the L300 come in?
A. The L300 Foot Drop System comes in two sizes: regular and small (to fit calf circumferences approximately 12 inches or smaller).
Q. What are the potential benefits of the L300 Foot Drop System?
A. The L300 Foot Drop System is cleared for the following indications:
  • Provides ankle-foot dorsiflexion which may improve gait
  • Reeducates muscles1
  • Prevents muscle disuse atrophy (muscle loss)
  • Maintains or increases joint range of motion
  • Increases local blood flow
Q. Is the L300 Foot Drop System only for Stroke patients?
A. No. It can be used for Multiple Sclerosis, Spinal Cord Injuries and Traumatic Brain Injury.
Q. Do I need to have foot and ankle movement to use the L300 Foot Drop System?
A. No. However, your physician will determine if the system is appropriate for you.
Q. When can I start using the L300 Foot Drop System?
A. Ideally, use begins during inpatient rehabilitation and continues at home.
Q. How long could I benefit from the L300 Foot Drop System?
A. The L300 Foot Drop System is designed to provide benefits over a lifetime of use, or as medically appropriate. Many factors may affect your outcome, including severity of impairment, age, time elapsed since the impairment, co-morbidities, pre-existing conditions, therapy compliance and overall cognition. Length of use also may depend on whether the goal is to manage impairment or improve function.


Q. How do I obtain the L300 Foot Drop System for home use?
A. You will need to obtain a prescription for therapy and be evaluated by a Bioness-trained healthcare provider. If you are considered a candidate, the next step will be to complete the Patient Forms Packet, which consists of:
  • A letter of medical necessity and device prescription
  • A checklist for custom fitting
  • A release of patient and insurance information
Bioness works closely with you and your healthcare provider during the acquisition process.
Q. Does the L300 Foot Drop System require a prescription?
A. Yes. In order to acquire the device for home use, a prescription from your physician is required.
Q. Is the L300 Foot Drop System covered by my insurance?
A. Use of a Bioness system in the clinic setting is billed by your healthcare professional and often reimbursed if it is medically necessary. While we can’t guarantee insurance reimbursement when a Bioness system is purchased for home use, your health insurance plan may cover some or all of the cost of a Bioness system. Claims submitted for reimbursement of a Bioness system are often evaluated on a case-by-case basis.
Q. Are there financing options for the L300 Foot Drop System?
