L300
Clinical Aspects
The NESS L300 system is intended for improving gait in people suffering
from drop foot as a result of a central nervous system injury or disease.
Drop foot is the inability or partial ability to raise the foot and toes toward
the body (dorsiflexion). This condition is a common result of impairment
or injuries to the central nervous system such as stroke, traumatic brain
injury, multiple sclerosis, or cerebral palsy. Patients with drop foot tend
to drag their foot during the swing phase of walking and usually try to
compensate for the dragging by hiking their hip or swinging it in a
circular motion (circumduction). These patients tend to be less stable,
suffer the risk of frequent falls, and expend more energy when walking.
The NESS L300 is intended to provide ankle dorsiflexion in individuals
with drop foot. During the swing phase of gait, the NESS L300
electrically stimulates muscles in the weak leg to provide flexion of the
foot; thus, it may improve the individual’s gait. The NESS L300 also may
facilitate muscle re-education, reduce muscle spasm, prevent/retard
disused atrophy, maintain or increase joint range of motion and increase
local blood flow.
Advanced Technology in Rehabilitation
The NESS L300 system is comprised of an electronic orthosis, a foot
sensor, and a control unit, which are ergonomically designed and
aesthetically pleasing. The advanced ergonomic design of the orthosis
ensures constant and snug contact of each electrode during limb motion
and muscle contraction.
