L300 Go System

 

Indications for Use

The L300 Go System is intended to provide ankle dorsiflexion in adult and pediatric individuals with foot drop and/or to assist knee flexion or extension in adult individuals with muscle weakness related to upper motor neuron disease/injury (e.g., stroke, damage to pathways to the spinal cord). The L300 Go System electrically stimulates muscles in the affected leg to provide ankle dorsiflexion of the foot and/or knee flexion or extension; thus, it also may improve the individual's gait.  

The L300 Go System may also:

• Facilitate muscle re-education
• Prevent/retard disuse atrophy
• Maintain or increase joint range of motion
• Increase local blood flow

Contraindications

• Users with a demand-type cardiac pacemaker, defibrillator or any electrical implant should not use the L300 Go System.

Warnings

• The L300 Go System should not be used on a leg where a metallic implant is directly underneath the electrodes.
• The L300 Go System should not be used on a leg where a cancerous lesion is present or suspected.
• The L300 Go System should not be used on a leg with a regional disorder, such as a fracture or dislocation, which could be adversely affected by motion from the stimulation.
• The long-term effects of chronic electrical stimulation are unknown.
• The Lower Leg Cuff and Thigh Cuff should not be worn over swollen, infected, or inflamed areas or skin eruptions, such as phlebitis, thrombophlebitis, and varicose veins.
• Simultaneous connection of the L300 Go System to the patient and high frequency surgical equipment may result in skin burns where the stimulator electrodes touch and damage to the EPG
• Do not use the L300 Go System within three feet of short wave or microwave therapy equipment. Such equipment may produce instability in the EPG output.
