L300 Functional Stimulation (FS) Cuff
The L300 FS Cuff fits on the affected leg below the knee. See Figure 5-1. The
L300 FS Cuff is designed to facilitate dorsiflexion of the foot. It is lightweight,
easy to put on with one hand, and can be worn under loose clothing.
The L300 FS Cuff features a radio frequency (RF) stimulation unit that
communicates wirelessly with the L300 Plus Control Unit and Intelli-Sense
Gait Sensor.

Locator
The locator fits under the kneecap of the affected leg. The locator is used
to accurately place the L300 FS Cuff on the leg, and to ensure repeatable
electrode contact.
Cradle
The cradle holds the L300 RF Stim Unit. The L300 RF Stim Unit snaps in
and out of the cradle.
Note: The L300 RF Stim Unit should only be removed for maintenance and
when cleaning the L300 FS Cuff.
Strap
The L300 FS Cuff strap is adjustable and has a flexible handle, which fits
over the cradle to fasten.
L300 Electrodes and Electrode Bases
The following electrodes may be used with the L300 FS Cuff:
•Large Cloth Electrode, L300 systems.
•L300 Hydrogel Electrodes and Hydrogel Electrode Bases.
•L300 Cloth Electrodes and Cloth Electrode Bases.
The electrodes attach to the inside of the L300 FS Cuff. Your clinician will
determine the type of electrodes most appropriate for you and then fit the
electrodes to your L300 FS Cuff.
CAUTION: Do not wear the L300 FS Cuff without electrodes.

L300 RF Stim Unit
The L300 RF Stim Unit generates the electrical stimulation used to dorsiflex
the foot. It responds to wireless signals from the L300 Plus Control Unit and
the Intelli-Sense Gait Sensor to turn stimulation on/off.
The L300 RF Stim Unit includes a status light, a stimulation light, and a
rechargeable battery. The battery charging port is located at the top of the
L300 RF Stim Unit, under the flexible cover. See Figure 5-2.

Thigh FS Cuff
The Thigh FS Cuff is a lightweight, low-profile orthosis designed to assist
with knee flexion or extension. See Figure 5-3. The Thigh FS Cuff fits above
the affected knee, centered on the back or front of the thigh.
The Thigh FS Cuff features an RF stimulation unit that communicates wirelessly
with the L300 Plus Control Unit and Intelli-Sense Gait Sensor.

Panels
The Thigh FS Cuff features two panels. The top panel fits higher on the thigh.
The bottom panel fits lower on the thigh. The bottom panel has a cradle for
the Thigh RF Stim Unit.
Elongation Bar
The elongation bar connects the top and bottom Thigh FS Cuff panels. Your
clinician will adjust the elongation bar and lock it.
Locator
The Thigh FS Cuff locator should rest on the center of the thigh, three finger
widths from the knee of the affected leg. The locator is used to accurately
place the Thigh FS Cuff on the leg, and to ensure repeatable electrode contact.
Cradle
The cradle holds the Thigh RF Stim Unit. The Thigh RF Stim Unit snaps in

Thigh Cloth Electrodes
The Thigh FS Cuff uses two cloth electrodes to provide electrical stimulation.
The large Thigh cloth electrode snaps to the Thigh FS Cuff top panel. The
small Thigh cloth electrode snaps to the Thigh FS Cuff bottom panel. See

Operating Modes
The L300 Plus System has three operating modes: standby, gait, and training.
Standby Mode
In standby mode, the NESS L300 Plus System is on and waiting for commands.
Stimulation is off.
Gait Mode
Gait mode is used when walking. In gait mode, the Intelli-Sense Gait Sensor
signals the L300 and Thigh RF Stim Units when the heel leaves the ground
and when the heel contacts the ground. Stimulation in the L300 and Thigh
RF Stim Units respond as programmed by the clinician.
Training Mode
Training mode is used to train the muscles when not walking (for example,
sitting or lying down). Training mode works independently of the Intelli-Sense
Gait Sensor. Stimulation is delivered in cycles pre-set by the clinician.
Training mode is designed to:
•Facilitate muscle re-education.
•Prevent or retard disuse atrophy of the lower leg and thigh muscles.
•Maintain or improve range of motion of the ankle and knee joints.
•Improve local blood circulation.
