Brief Summary:
The purpose of this study is to evaluate the safety and efficacy of the BrainPort balance device in improving balance in people with balance deficits due to stroke.

Condition or disease Intervention/treatment Phase
Cerebrovascular Accident Device: BrainPort Balance Device Not Applicable

Detailed Description:
Following baseline assessments, subjects participate in 5 consecutive days (10 hours) of clinic training with the BrainPort balance device with a Physical Therapist. Assessments are repeated at the end of clinic training. Following clinic training, subjects take the device home to use for two (2) 20 minute training sessions each day. Subjects return to the clinic for one (1) day of testing after using the device at home for 7 weeks.

Study Type : Interventional  (Clinical Trial)
Actual Enrollment : 29 participants
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Substitute Vestibular Information System Using the BrainPort® Balance Device for Adults With Chronic Vestibular Dysfunction Following Stroke
Study Start Date : June 2007
Actual Primary Completion Date : April 2010
Actual Study Completion Date : April 2010

Intervention Details:
  • Device: BrainPort Balance Device
    The BrainPort balance device, is a non-invasive medical device that provides head and body position information to a person via their tongue.
