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.
Condition or disease
Device: balance prosthesis
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.
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.
