本研究的目的是确定在何种程度上的感觉统合策略，通过头部摇摆，来自头戴式显示器（HMD），改变前庭障碍的人前庭康复。随机对照试验前庭康复诊所30名前庭功能障碍的参与者和21名年龄匹配的对照。参与者经历了两个级别的视觉环境（静态或移动的“星星”，前后为0.2 Hz，32 mm）和白色噪音（无或有节奏），同时通过HTC Vive记录他们的头部摆动。我们通过方向路径（DP）和均方根速度（RMSV）在5个方向上量化头部摆动：前-后，中-外，俯仰，偏航和滚动以及前-后方向上低（PSD 1），中（PSD 2）和高（PSD 3）频率的功率谱密度。参与者在随机分配到虚拟现实或传统前庭康复中进行8周的情境感觉统合训练之前进行评估，并在完成干预后再次进行评估。对照组进行一次评估。12名参与者退出，其中一半是由于新型冠状病毒封锁。我们采用意向治疗分析。我们观察到AP DP，RMSV和所有PSD随视觉水平的变化而显著增加。两个干预组均显著降低了内外侧、俯仰和翻滚DP和RMSV以及前后PSD 2，无组间差异。前庭参与者在康复前的所有结果均显着高于对照组。康复后，他们只是显着更高的PSD 2。在本方案中，声音不是头部摆动的重要预测因素。头摆动减少前庭康复后，无论视觉负荷或类型的干预应用。通过从便携式HMD获得的头部运动学测量该变化，该HMD可作为随时间推移跟踪改善的灵敏临床评估NCT 04268745
The purpose of this study was to determine the extent to which sensory integration strategies via head sway, derived from a Head-Mounted Display (HMD), change in people with vestibular disorders following vestibular rehabilitation. Randomized Controlled Trial Vestibular Rehabilitation Clinic Thirty participants with vestibular dysfunction and 21 age-matched controls. Participants experienced two levels of visual surround (static or moving ‘stars’, front to back at 0.2 Hz, 32mm) and white noise (none or rhythmic) while their head sway was recorded via the HTC Vive. We quantified head sway via Directional Path (DP) and Root Mean Square Velocity (RMSV) in 5 directions: anterior-posterior, medio-lateral, pitch, yaw, and roll and Power Spectral Density in low (PSD 1), medium (PSD 2) and high (PSD 3) frequencies in the anterior-posterior direction. Participants performed the assessment prior to being randomized into 8-weeks of contextual sensory integration training in virtual reality or traditional vestibular rehabilitation and once again following completion of the intervention. Controls performed the assessment once. Twelve participants dropped out, half due to covid lock-down. We applied an intention to treat analysis. We observed significant increases in AP DP, RMSV and all PSDs with change in visual level. Both intervention groups significantly decreased medio-lateral, pitch and roll DP and RMSV and anterior-posterior PSD 2 with no group differences. Vestibular participants were significantly higher than controls on all outcomes pre rehabilitation. Post rehabilitation they were only significantly higher on PSD 2. Sound was not a significant predictor of head sway in this protocol. Head sway decreased following vestibular rehabilitation regardless of visual load or type of intervention applied. This change was measured via head kinematics derived from a portable HMD which can serve as a sensitive in-clinic assessment for tracking improvement over time NCT04268745
