Effects of Vestibular Training on Postural Control of Healthy Adults Using Virtual Reality

What this Trial Is About

Postural instability caused by vestibular dysfunction can affect daily activities. Researchers are evaluating a new training method called concurrent headshake and weight shift training (Concurrent HS-WST) using virtual reality to improve balance and vestibular function in healthy young adults. This approach aims to engage sensory reweighting and enhance vestibular reflexes more effectively than traditional methods. The study is conducted by Clarkson University and focuses on healthy adults aged 18 to 35 years. Participants will undergo vestibular activation training involving headshake and weight shift exercises while wearing a virtual reality headset. The study uses a randomized crossover design where one group receives the training for 6 days followed by a 4-day break and then no training for 6 days, while the other group follows the reverse sequence. Safety measures include an overhead harness and a spotter to prevent falls during training. During the two-week study, participants will perform postural assessments, reactive balance tests after mechanical perturbations, and headshake activities. Researchers will measure vestibulo-ocular reflex (VOR) gain, eye movement variability, electromyography (EMG) amplitude and timing, balance scores, and sensory ratios. These evaluations will help understand the effects of the training on vestibular and postural control. Participants' adherence and safety will be closely monitored throughout the study.
