VIII User's Guide
1Chapter 1 - Introduction1IntroductionCentral nervous system (CNS) injuries and diseases often cause a gait disorder called foot drop. People who have foot drop are unable to raise their foot while walking. They often drag their foot, resulting in instability and increased effort during gait. Many people with CNS injuries/diseases also suffer from thigh muscle weakness. Weak thigh muscles can cause considerable difficulties with flexing or extending the knee during ambulation.The NESS L300 Plus System is intended to provide ankle dorsiflexion and knee flexion or extension in individuals with foot drop and thigh muscle weakness following an upper motor neuron injury or disease.This NESS L300 Plus User’s Guide describes: xImportant safety information about the NESS L300 Plus System. xThe components of the NESS L300 Plus System. xHow to set up, operate, and maintain the NESS L300 Plus System. xTroubleshooting information.Be sure to review this guide with your clinician before using the NESS L300 Plus System. If you have clinical or technical questions, consult your clinician or the Bioness Client Relations Department at (800) 211-9136, Option 3, or visit the Bioness website: www.bioness.com.CAUTION: Do not put on or operate the NESS L300 Plus System before being properly fitted and trained by a certified clinician.
