    They often drag their foot, resulting in instability and increased effort during gait. The NESS L300 Foot Drop System is an advanced neuroprosthesis designed to improve gait in people suffering from foot drop. The L300 System incorporates cutting-edge technology and sophisticated design features to improve walking and quality of life.
  • Page 9 L300 System. Be sure to review this guide with your clinician. If you have any questions contact the Bioness Client Relations Department at (800) 211-9136, Option 3 (in the United States) or your local distributor (outside of the United States). You can also visit the Bioness website at: www.bioness.com.

  • Page 10: Chapter 2: Safety Information

    During the swing phase of gait, the NESS L300 electrically stimulates muscles in the affected leg to provide dorsiflexion of the foot. The NESS L300 may improve gait, facilitate muscle re-education, prevent or retard disuse atrophy, maintain or increase joint range of motion, and increase local blood flow.

  • Page 11: Precautions

    • In case of any inconvenience, turn off stimulation and remove the L300 FS Cuff. If the stimulation cannot be turned off, remove the L300 FS Cuff to stop stimulation. Precautions • Inflammation in the region of the L300 FS Cuff may be aggravated by motion, muscle activity, or pressure from the L300 FS Cuff.
  • Page 12 -20°C to +60°C (-4°F to +140°F). Temperature extremes can damage the components. • Do not attempt to repair your L300 System. Contact Bioness if you experience a technical problem not covered in this guide. • The L300 FS Cuff is to be worn only on the leg of the patient for whom it is fitted. It should not be worn by anyone else or on any other part of the body.

  • Page 13: Adverse Reactions

    • Medical electrical equipment needs special precautions for electromagnetic compatibility. • Remove the L300 System before undergoing any diagnostic or therapeutic medical procedure such as x-ray examination, ultrasound, MRI, etc. Adverse Reactions In the unlikely event that any of the following occurs, stop using your L300 System immediately and consult your physician.
  • Page 14 If skin irritation or a skin reaction occurs, stop using your L300 System immediately and contact your clinician or dermatologist. Also contact the Bioness Client Relations Department: (800) 211-9136, Option 3 (in the United States) or your local distributor (outside the United States).

  • Page 26: Intelli-Sense Gait Sensor

    Intelli-Sense Gait Sensor The Intelli-Sense Gait Sensor detects when your foot is in the air and on the ground, and wirelessly signals the other L300 System components. The Intelli-Sense Gait Sensor features a pressure sensor and a transmitter. See Figure 5-4. The pressure sensor fits under the insole of your shoe.

  • Page 27: Control Unit

    Control Unit The Control Unit is used to turn on/off the system, select an operating mode, fine-tune stimulation intensity, adjust audio alert volume, and monitor system performance. See Figure 5-5. The Control Unit communicates wirelessly with the RF Stim Unit and Intelli- Sense Gait Sensor.

  • Page 28: Operating Buttons

    Gait Mode Gait mode is used when walking. In gait mode, the Intelli-Sense Gait Sensor signals the RF Stim Unit when your heel or forefoot leaves the ground, turning stimulation on. It also signals when your heel or forefoot contacts the ground, turning stimulation off. Training Mode Training mode is used to train muscles when you are not walking (for example, sitting or lying down).

  • Page 42: Chapter 7: Operating The L300 System

    Operating the L300 System RF Communication Safety Features The Control Unit, RF Stim Unit, and Intelli-Sense Gait Sensor must be within RF communication range of each other and their batteries charged for the L300 System to operate. If the components become separated, or if a battery is discharged, RF communication will be lost and the system will stop working until RF communication is restored.

  • Page 43: Training Mode

    Training Mode To select training mode, turn on the Control Unit. Press and hold the mode button until the Control Unit beeps, the mode button starts flashing yellow slowly (indicating that stimulation is off), and the letter "t" alternates with the intensity level in the digital display. When stimulation is on, the mode button will flash yellow rapidly.

  • Page 44: Adjusting The Volume Of Audio Alerts

    Adjusting the Volume of Audio Alerts Use the volume buttons to adjust the volume of the audio alerts. Each time one of the buttons is pressed, the volume level will change.
