19Chapter 5 - NESS L300 Plus System5NESS L300 Plus SystemL300 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.Figure 5-1: L300 FS Cuff.LocatorStrap HandleCradle L300 RF Stim UnitStrap
20 User's GuideLocatorThe 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.CradleThe 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.StrapThe L300 FS Cuff strap is adjustable and has a flexible handle, which fits over the cradle to fasten.L300 Electrodes and Electrode BasesThe 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.
21Chapter 5 - NESS L300 Plus SystemL300 RF Stim UnitThe 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.Figure 5-2: L300 RF Stim Unit.Charging Port under Flexible CoverCradleStatus LightStimulation LightL300 RF Stim Unit

23Chapter 5 - NESS L300 Plus SystemThigh 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.Figure 5-3: Thigh FS Cuff.CradleLocatorElongation Bar Thigh RF Stim UnitTop PanelBottom Panel
24 User's GuidePanelsThe 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 BarThe elongation bar connects the top and bottom Thigh FS Cuff panels. Your clinician will adjust the elongation bar and lock it. LocatorThe 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. CradleThe cradle holds the Thigh RF Stim Unit. The Thigh RF Stim Unit snaps in and out of the cradle.Note: The Thigh RF Stim Unit should only be removed for maintenance and when cleaning the Thigh FS Cuff.
25Chapter 5 - NESS L300 Plus SystemFigure 5-4: Snapping the small Thigh cloth electrode to the bottom panel.CAUTION: Do not wear the Thigh FS Cuff without the cloth electrodes.Thigh Cloth ElectrodesThe 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 Figure 5-4.

32 User's GuideOperating ModesThe L300 Plus System has three operating modes: standby, gait, and training. Standby ModeIn standby mode, the NESS L300 Plus System is on and waiting for commands. Stimulation is off.Gait ModeGait 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 ModeTraining 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.
