About

This is a preliminary study of how human beings control balance and how symptoms of visually-induced dizziness may result in falls. The researchers created new tests of orientation and balance, as well as a new treatment for visually-induced dizziness. The researchers will use the new tests and treatments with adults who are affected by visually-induced dizziness. Testing is done twice before and once after treatment. The total time participants are involved in the study is approximately two weeks.

Full description

This is a preliminary study of how human beings control balance and how symptoms of visually-induced dizziness may result in falls. The researchers created new tests of orientation and balance, as well as a new treatment for visually-induced dizziness. It is not known whether the new tests of orientation and balance are better, worse, or the same as existing tests in the ability to detect problems, nor is it known if the new treatment technique is any better, worse, or the same as existing treatments for dizziness and imbalance. However, the researchers hypothesize that the new tests will improve the ability to detect problems. They hypothesize that the treatment will result in less dizziness, better balance, and reduced risk of falling for those who receive it and that it is a better alternative to treatments that are already available to patients.

In order to see if this is true, the researchers will use the new tests and treatments with adults who are affected by dizziness. All participants in this study will undergo the same tests and will receive the same treatment. Testing is done twice before and once after the treatment period. The tests and treatment are done while standing on a computerized platform that measures balance and can tilt people from side to side. During these study procedures, participants wear virtual reality goggles that show them simple images in an otherwise dark environment.

The goal of the tests and the treatment is for participants to use what they feel to help them decide if the images shown inside the goggles are aligned with the person's sense of gravity. Participation in this study is voluntary and people who decide to participate may stop at any time without penalty.

Sensory Re-weighting

Experimental group

Description:

Adults with self-reported visually-induced dizziness will be recruited to help establish the feasibility and tolerability of the testing and training methods, as well as observe for any effects of the sensory re-weighting intervention. Tests involve assessing motion sickness, vision, somatosensation, balance, and perception of verticality. The treatment provided is designed to facilitate re-weighting of sensory feedback for orientation and balance. Participants will serve as their own controls.

Treatment:

Behavioral: sensory re-weighting
