Abstract

vestibular system. The usual symptoms are persistent unsteadiness and oscillopsia during head and body movements. It has been reported that sensory substitution therapy, that is, vestibular rehabilitation using a sensory substitution device, which transmits other sensory information to a stimulator as a substitute for defective vestibular information, might be effective in patients with bilateral and unilateral vestibulopathy. Recently, we developed a new wearable device, TPAD (tilt perception adjustment device), that transmits vibratory input containing head-tilt information to the mandible as a substitute for defective vestibular information. We assessed the patient using the dizziness handicaps inventory (DHI), gait analysis, and visual/somatosensory dependence of postural control in the patients with unilateral vestibulopathy. Three months after therapy in patients with unilateral vestibulopathy, the DHI and walking speed improved even when the subjects were not wearing the TPAD. Moreover, the index of the visual dependence of posture control that was evaluated by posturography with/without foam rubber in the eyes open or closed condition decreased. The findings suggested that the sensory vibratory substitution with a TPAD for defective vestibular information induced brain plasticity related to sensory re-weighting to reduce the visual dependence of posture control, resulting in the improvement of dizziness and imbalance even while not wearing the TPAD in vestibulopathy patients. We then investigated the effects of sensory substitution therapy using a TPAD in patients with bilateral vestibulopathy and normal subjects. Three months after sensory substitution therapy in patients with bilateral vestibulopathy, the DHI and area with eyes closed measured by posturography improved even when the subjects did not wear a TPAD. However, the gait parameters improved only under the condition of wearing a TPAD. These findings suggest that sensory vibratory substitution with a TPAD might serve as temporary replacement for defective vestibular information in patients with bilateral vestibulopathy. Moreover, wearing of the TPAD improved posture control under the eyes-closed condition with foam rubber measured by posturography in normal subjects. TPAD might be applicable as a wearable device for improving posture control, not only in patients with bilateral vestibulopathy, but also in those with presbyvestibulopathy. シンポジウム「Bilateral vestibulopathy: How to treat and manage?」
使用倾斜知觉调节装置(TPAD)的感觉替代疗法治疗双侧前庭病变患者
前庭系统。常见的症状是在头部和身体运动过程中持续不稳定和摆动。据报道,感觉替代疗法,即使用感觉替代设备进行前庭康复,该设备将其他感觉信息传输到刺激器,以替代有缺陷的前庭信息,可能对双侧和单侧前庭病患者有效。最近,我们开发了一种新的可穿戴设备,TPAD(倾斜感知调节设备),它将包含头部倾斜信息的振动输入传输到下颌骨,以代替有缺陷的前庭信息。我们使用单侧前庭病患者的头晕障碍量表(DHI)、步态分析和姿势控制的视觉/体感依赖性来评估患者。单侧前庭病患者治疗三个月后,即使受试者没有佩戴TPAD,DHI和行走速度也有所改善。此外,在睁眼或闭眼条件下,通过使用/不使用泡沫橡胶的姿势描记术评估的姿势控制的视觉依赖性指数下降。研究结果表明,用TPAD代替有缺陷的前庭信息可诱导大脑可塑性,这与感觉重加权有关,以减少姿势控制的视觉依赖性,从而改善前庭病患者的头晕和不平衡,即使在不佩戴TPAD的情况下也是如此。然后,我们研究了使用TPAD的感觉替代疗法对双侧前庭病变患者和正常受试者的影响。双侧前庭病患者在接受感觉替代治疗三个月后,即使受试者没有佩戴TPAD,通过姿势描记术测量的DHI和闭眼面积也有所改善。然而,步态参数只有在佩戴TPAD的情况下才有所改善。这些发现表明,用TPAD进行感觉振动替代可能是双侧前庭病患者前庭信息缺陷的临时替代品。此外,佩戴TPAD改善了正常受试者在闭眼条件下的姿势控制,通过姿势描记术测量泡沫橡胶。TPAD可能作为一种可穿戴设备用于改善姿势控制,不仅适用于双侧前庭病患者,也适用于老年前庭病患者。シンポジウム「双侧前庭病变:如何治疗和管理?」
