Walkasins is a wearable, non-invasive lower limb sensory neuroprosthesis intended to replace the nerve function used for detection and signaling of foot pressure sensation. Indicated for use by individuals with lower limb sensory peripheral neuropathy who present with gait and balance impairments and are at high risk of falls.

Item 8: Gait with Eyes Closed
“Walk at your normal pace from here to the next mark [20ft.] with your eyes closed.”
Walkasins replaces lost afferent nerve function on the bottom of the feet and restores important sensory information of body sway and foot contact with the ground to the central nervous system5.
Walkasins provides afferent nerve information to restore the ability to sense and communicate important plantar pressure information for gait and balance that is lost in patients with Sensory Peripheral Neuropathy.
Walkasins system consists of a Leg Unit worn around the ankle of each leg and a Foot Pad inserted under the user’s foot in their shoe.
Together, the two components mimic the function of the damaged sensory nerve receptors in the feet and restore important missing sensory information.
This sensory input is naturally used by the brain to control movement and balance function.
Walkasins is indicated for patients with lower limb sensory peripheral neuropathy who present with gait and balance impairments. Walkasins is indicated for patients who can feel the tactile stimuli from the Leg Unit on the lower leg.
