This study has been completed.
Sponsor:
Information provided by:
Neurostream Technologies G.P.
ClinicalTrials.gov Identifier:
NCT00860210
First received: March 11, 2009
Last updated: April 9, 2010
Last verified: April 2010
  Purpose
This pilot feasibility study is assessing the safety and technical performance of the Neurostep™ System for the restoration of independent gait in subjects with gait disorder (i.e. foot drop) secondary to a CNS lesion (e.g. stroke).

Condition Intervention Phase
Stroke Craniocerebral Trauma Device: Neurostep™ System Phase 1

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Pilot Feasibility Study of the Neurostep™ System in Subjects With Gait Disorder Secondary to CNS Lesion.

Further study details as provided by Neurostream Technologies G.P.:

Primary Outcome Measures:
  • Electrophysiological integrity of the nerves surrounded by the nerve cuffs assessed using Nerve Conduction Velocity (NCV) tests. Status Quo in physical examinations of the subject. [ Time Frame: Throughout the study period (23 weeks) ]

Secondary Outcome Measures:
  • Ability to stimulate the common peroneal nerve and selectively activate ankle dorsiflexor muscles to produce symmetrical motion of the foot. Ability to sense the heel-strike and toe-lift events during walking. [ Time Frame: From the surgical implantation to the end of the study (i.e. 20 weeks) ]

Enrollment: 14
Study Start Date: October 2007
Study Completion Date: March 2010
Primary Completion Date: November 2009 (Final data collection date for primary outcome measure)
Intervention Details:
    Device: Neurostep™ System
    The Neurostep™ System is a neurostimulation investigational medical device. The entire system is designed to be implanted into the subject's leg via a surgical procedure, during which electrodes are attached to the peripheral nerves responsible for sensing and stimulating the proper muscles that lift the foot during normal walking.
