  Purpose
The goal of this project is to provide individuals that have a balance deficit with a device that will give them signals that they can feel (vibrations) in order to help them maintain a correct sense of balance and perception of place in the environment.

Primary Outcome Measures:
  • Change in Dynamic Gait Index (DGI) From Baseline to 6 Weeks. [ Time Frame: 6 weeks ]
    The DGI is designed to measure a patient's functional balance and postural stability on a scale of 0-3 (3 being normal) for each task. A series of 8 tasks including walking on a level surface, walking while changing speeds, walking with head turns, walking then turning, stepping over obstacles, walking around obstacles, and stairs. For a total scale of 0-24.


Enrollment: 5
Study Start Date: February 2011
Study Completion Date: June 2012
Primary Completion Date: June 2012 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: prosthesis group
balance prosthesis
Device: balance prosthesis
vibrotactile stimulation

Detailed Description:
This proposal addresses a National Institute on Deafness and Other communication Disorders (NIDCD) research topic that emphasizes the "development of assistive devices for balance disorders". The proposed work will evaluate the assistive efficacy of such a balance prosthesis in a population of chronic imbalance patients spanning a wide range of disease etiologies.

Criteria

Inclusion Criteria:

  • Ambulatory patients who have had chronic imbalance for at least one year, and have reached a functional performance plateau with respect to their balance adaptation.

Exclusion Criteria:

  • Neurological disorders other than chronic balance disorders, as determined by medical history and neurological screening procedure.
  • Any medical condition as determined by the health questionnaire that would interfere with performance on the postural stability evaluation tests.
  • Peripheral neuropathies of the lower extremities.
  • Subjects who are unwilling or unable to adhere to all study requirements, including completion of the training period, evaluation tests, and return to clinic for a follow-up visit.
