Lower Extremity Neuroprosthesis

What is a Lower Extremity Neuroprosthesis?

  • A device used to treat “foot drop” during walking. Foot drop may result in tripping, falling, and decreased balance while walking.
  • The device delivers precisely timed pulses of electrical stimulation (E-stim) to muscles of the leg that lift the foot and help clear the toes during walking.
  • Wireless device (no visible wires as compared to conventional E-stim units).
  • Fits easily and goes unnoticed under most pants.
  • Can be worn with many different types and sizes of shoes. Can even be worn without shoes.
  • May take the place of an Ankle-Foot-Orthosis or AFO.
  • WalkAide and Bioness L300 are the names of two devices offered.

Who can use the device?

Patients with foot drop resulting from neurological disorders or injuries including:

  • Stroke
  • Cerebral Palsy
  • Traumatic Brain Injury
  • Incomplete Spinal Cord Injury

Patients that:

  • Have a pacemaker or defibrillator
  • Have a recent fracture or dislocation that is not yet healed
  • Are pregnant or planning to become pregnant
  • Have a malignant tumor, lesion, or open wound on affected leg
  • Have electric or metal implants
  • Have an irreversible contracture
  • Do not tolerate E-stim
  • Have severe osteoporosis (brittle bones or weak bones)
  • Have uncontrolled seizures.

How does it work?

  • A cuff is strapped to the lower leg.
  • The muscles that lift the foot and toes during walking are stimulated.
  • Advanced sensors are set to turn on at the correct time during walking.
  • A walking program is tailored to your child.
  • The device is wireless so there are no wires to keep track of.
