简要总结
This study evaluates the use of vibrotactile feedback to traditional vestibular treatment protocols. Half the patients will have vibrotactile feedback added to their treatment protocols while the other half will undergo traditional vestibular treatment without vibrotactile feedback.
详细描述
Vestibular and balance rehabilitation is an effective way to improve balance for individuals with balance impairments by using the strategies of adaptation, habituation, or substitution. Typical vestibular treatment is usually 3 sessions per week for 6 weeks. For people with uncompensated unilateral vestibular hypofunction or bilateral vestibular loss, recovery/adaptation is often incomplete and chronic balance impairments result.
Vibrotactile feedback (VTF) is a strategy of substitution, or augmentation, to replace disrupted or absent vestibular function. The sensory information replaces disrupted or absent vestibular function to give persons additional signals about their body position in space. Real-time VTF applied to the trunk has been shown to decrease postural sway but the long-term benefits of training with VTF on balance and function have not been examined.

研究组 & 干预措施
Vibrotactile Feedback
Balance exercises completed while vibration was applied to the trunk (anterior, posterior, right, and left) if postural sway exceeded a pre-determined threshold during the exercise.
干预措施: Vibrotactile Feedback (Other)
Without Vibrotactile Feedback
Balance training without feedback
结局指标
主要结局
Change in Five Times Sit to Stand
时间窗: Baseline, 3 weeks, 6 weeks, 10 weeks, & 30 weeks
A stopwatch is used to record the amount of time it takes the participant to move from a seated position to a standing position back to seated without using their hads for a total of 5 repetitions
Change in Sensory Organization Testing
时间窗: Baseline, 3 weeks, 6 weeks, 10 weeks, & 30 weeks
Postural sway data will be collected during Computerized Dynamic Posturography using the NeuroCom Equitest.
Change in 10-meter walk test
时间窗: Baseline, 3 weeks, 6 weeks, 10 weeks, & 30 weeks
Participants preferred gait velocity will be assessed while walking in a straight path by timing 10-meter walk.
Change in Dynamic Gait Index and Functional Gait Assessment
时间窗: Baseline, 3 weeks, 6 weeks, 10 weeks, & 30 weeks
Measures that assess ability to modify walking in the presence of external demands. Includes tasks such walking with head turns, walking around obstacles, stepping over obstacles, and negotiating stairs. Each task is scored on a 4 point scale (0-3) and a total score is compiled.
次要结局
- Change in Activities-specific Balance Confidence Scale(Baseline, 3 weeks, 6 weeks, 10 weeks, & 30 weeks)
- Change in Short Form-12(Baseline, 3 weeks, 6 weeks, 10 weeks, & 30 weeks)
- Change in Dizziness Handicap Inventory(Baseline, 3 weeks, 6 weeks, 10 weeks, & 30 weeks)
