Summary

This is a preliminary study to determine the reliability and validity of new tests of orientation and balance, as well as to test the effects of a new treatment for visually induced dizziness. Tests involve determining vertical alignment. The treatment is task-based and involves focusing attention on internal body sensations to help improve the sense of upright. Testing is done twice before and twice after treatment, which is provided twice-weekly during a three-week period between testing. The total time participants are involved in the study is approximately six weeks.

Interventions

BEHAVIORAL

Sensory re-weighting

During training, sensory re-weighting is driven by priming upregulation of somatosensory cues. Two rounds of training, each lasting 15 minutes and block-randomized in sets of 10 trials, are conducted per training visit. In each training trial, participants must determine the direction of gravity and then indicate if the rod being displayed is aligned with gravity or if it needs to rotate clockwise or counterclockwise for that to be so. Participants will be instructed to pay attention to what they feel from their feet, legs, and gut during training and to use that pressure, stretch, movement, and muscle tension feedback to help them sense gravity. Immediate auditory and non-orienting, visual feedback is provided after each trial. A staircase method is used to adapt the level of difficulty based on response accuracy. After two consecutive correct responses, the difficulty increases. After each incorrect response, the difficulty decreases. This process is repeated in each round.
