you’d rather not even attempt them. This limits your freedom of movement,
impacts your quality of life, and can even result in depression.
Are you ready to see if WalkAide
can change your life?
No matter how long you’ve been struggling with foot drop, you may be a good candidate for WalkAide, especially if

regain their freedom of movement…
WalkAide uses patented sensor technology to analyze the movement of your
leg. The system sends electrical signals to your peroneal nerve, which controls
movement in your ankle and foot. These gentle electrical impulses activate
the muscles to raise your foot at the appropriate time during each step. The
resulting movement is a smoother, more natural and safer walking motion.

How does WalkAide
Using WalkAnalyst software, your clinician evaluates your gait pattern and creates a customized walking program just for
you, sending it to your device via Bluetooth® connection. This custom program sends signals to the peroneal nerve to

raise the foot at the appropriate time during walking.
WalkAide is surprisingly small, powered by a single AA battery, and quite easy to operate and maintain. The non-invasive
device is worn directly over the skin — not implanted underneath the skin — which means no surgery is involved. A cuff
holds the system comfortably in place and it can be worn discreetly under most clothing.
Because WalkAide requires no heel sensor, you can wear almost any type of footwear and possibly even go barefoot.
Don’t wait another day to get YOUR life back.

Important Scientific Benefits
of WalkAide
WalkAide is considered a “neuroprosthesis” — a device
How else does WalkAide benefit me?
WalkAide also includes a programmable exercise mode that allows you to strengthen your muscles for a set period
of time while resting (as prescribed by your doctor). As you improve, your clinician can download an activity report
that replaces or improves function that has been lost due
that shows your progress between sessions. Using this information, your WalkAide can be reprogrammed to take into

Stimulation (FES), or gentle electrical impulses, to activate
the peroneal nerve in the leg, causing the foot to lift.
Regain your strength and independence.
Employing FES in rehabilitation has shown several important
benefits, including:
Increase your ability to
interact with loved ones.
•Improvement in gait, including increased gait speed 1-6
• Increased gait quality
• Increased coordination and balance
With WalkAide you will enjoy:
•Increased muscle strength and force of voluntary
contraction 11-12
• Decreased energy cost of gait
• Decreased spasticity
•Easy one-handed application and operation
•Improved walking speed and quality with less fatigue
• Reduced strain on other parts of your body
•The wearing of almost any type of shoe, or no shoes (upon
approval of your healthcare provider)
FES and Neuroplasticity:
An Exciting Scientific Finding
Recent evidence has shown that using FES can promote. positive changes in the function of the
brain, called neuroplasticity, resulting in overall functional improvement.
Several studies of FES-enabled devices have shown an increase in Motor Evoked Potential (MEP)
•Recovered use of your own muscles (with a WalkAide exercise
program created by your medical team)
•Minimal contact with your skin for greater comfort and
reduced perspiration
•Reduced atrophy and potential improvements in circulation,
muscle condition, and bone density
•Improved voluntary control, increased joint range of motion,
and cardiovascular health
— the measure of the strength of the connection between an area in the brain and the muscle
it drives — and an extension of cortical activation after FES treatment. 2,13,17 In other words,
the evidence is strong that FES technology not only improves functional outcomes, but in fact
facilitates true healing and central nervous system recovery.
“I had a family wedding where I saw relatives I had not seen since before the stroke. I wore a dress,

which I never would have done with the old brace. I was very comfortable and very confident that I could
walk and keep my balance. It was an outdoor wedding and I had no trouble walking in the grass.”

Traumatic Brain Injury
Foot drop is often caused by damage to the brain or spinal cord that creates a disruption to the peroneal nerve
function, resulting in weakness or paralysis of the muscles involved in lifting the front part of the foot.
