How our brain represents our body through the integration of internal and external sensory information so that we can interact with our surrounding environment has become a matter of interest especially in the field of neurorehabilitation. In this regard, there is an increasing interest in the use of multisensory integration techniques-such as the use of body ownership illusions-to modulate distorted body representations after brain damage. In particular, cross-modal illusions such as mirror visual feedback therapy (MVFT) have been widely used for motor rehabilitation. Despite the effectiveness of the MVFT for motor rehabilitation, there are some limitations to fully modify the distorted internal representation of the paretic limb in patients with stroke. A possible explanation for this relies on the physical limitations of the mirror in reproducing upper-limb distortions, which can result in a reduced sense of ownership of the mirrored limb. New digital technologies such as virtual reality (VR) and 360° videos allow researchers to create body ownership illusions by adapting virtual bodies so that they represent specific morphological characteristics including upper-limb distortions. In this manuscript, we present a new rehabilitation approach that employs full virtual body ownership illusions, using a 360° video system, for the assessment and modulation of the internal representation of the affected upper limb in stroke patients. We suggest modifying the internal representation of the upper limb to a normal position before starting motor rehabilitation training.
我们的大脑如何通过整合内部和外部感官信息来表征我们的身体,以便我们能够与周围环境进行互动,这已成为一个备受关注的问题,尤其是在神经康复领域。在这方面,人们对使用多感官整合技术(如利用身体所有权错觉)来调节脑损伤后扭曲的身体表征越来越感兴趣。特别是,诸如镜像视觉反馈疗法(MVFT)等跨模态错觉已被广泛用于运动康复。尽管MVFT对运动康复有效,但在完全修正中风患者患侧肢体扭曲的内部表征方面仍存在一些局限性。对此的一种可能解释是,镜子在再现上肢扭曲方面存在物理限制,这可能导致对镜像肢体的所有权感降低。虚拟现实(VR)和360°视频等新数字技术使研究人员能够通过调整虚拟身体来创造身体所有权错觉,使其呈现包括上肢扭曲在内的特定形态特征。在本手稿中,我们提出了一种新的康复方法,即使用360°视频系统,通过完全虚拟身体所有权错觉来评估和调节中风患者患侧上肢的内部表征。我们建议在开始运动康复训练之前,将上肢的内部表征修正到正常位置。
