Bringing balance to people
with peripheral neuropathy

Technology Overview

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.
  • 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.
The principle focus for the design and development of the Walkasins technology is on the somatosensory system and the need to replace plantar pressure sensation in patients with Sensory Peripheral Neuropathy, thereby helping to improve their balance.

 

Product Step 1

Sensory Peripheral Neuropathy (SPN)

Sensory Peripheral Neuropathy, or SPN, is a type of nerve damage that frequently affects sensory nerves in the soles of the feet that are responsible for signaling sense of touch, pressure and vibration – information that is crucial for our sense of balance.1,2,3
In individuals with SPN, the ability to accurately sense, measure and communicate plantar pressure information is compromised due to afferent nerve damage, often resulting in poor or staggered gait, which increases the risk of falls with the potential for serious injury.
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.

Indication for Use

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.
