# Personalized Visualization of the Gestures of Parkinson's Disease Patients with Virtual Reality
## 2 Background and Related Work
### Current State-of-the-Art: Conclusions  
This literature review brings together findings from several studies on the applications of immersive technologies, such as virtual and augmented reality, in the treatment and evaluation of neurodegenerative diseases. The 30 comprehensive studies selected cover a wide range of applications of these technologies, focusing mainly on [PERSON]'s disease (PD). The findings of the bibliographic review were divided into three main themes. The first subject is where we find applications using immersive or modern technologies for neurodegenerative diseases. In this category interesting approaches were identified such as treatment of muscle tension in patients with Parkinson's disease, using serious games and virtual reality in combination with an orthosis brachoid [9], a low-cost virtual reality interface to support the assessment and diagnosis of neurodegenerative diseases in a clinical setting [10], a virtual environment that provides misleading visual stimuli to subjects to induce imbalance events [11], use of evidence-based embedded virtual environments that integrate compensatory techniques like feedback and encouragement through guidance with movement learning [12], augmented reality for the assessment of motor dysfunction in the upper limbs of patients with Parkinson's disease and stroke [13], rehabilitation of patients with Parkinson's disease through the development of a serious game based on augmented reality [14], a functional capacity assessment tool with virtual reality (VRFCAT-SL) in clinical evaluations of patients with Parkinson's disease [15], use of virtual reality as a tool to assess balance in patients with Parkinson's disease [16], effects of visual feedback on the walking abilities of patients with Parkinson's disease [17], regulatory control of body posture in patients with idiopathic Parkinson's disease (IPD), using kinematics and frequency analysis [18], use of a virtual reality (VR)-based gait management strategy to improve gait symmetry in Parkinson's disease patients exhibiting gait freezing [19], use of robotic gait training (RAGT) with a Lokomat device in the treatment of patients with Parkinson's disease [20], a telerabilitation program using a mobile virtual reality system to simultaneously train two patients with Parkinson's disease in their homes [21], diagnosis of neurodegenerative diseases such as Parkinson's disease using a low-cost virtual reality interface [10], the effect of dopaminergic therapy and visual flow modulation on distance estimation in patients with Parkinson's disease [22], the use of a virtual reality system to simulate and adapt interior apartment features for people with [PERSON]'s disease [23], the effects of upper extremity virtual reality exercises (ULVRE) on upper extremity sensorimotor function in patients with idiopathic Parkinson's disease [24], the Internet of Medical Things (IoMT) with the development of an advanced system incorporating flexible sensors triboelectricity and deep learning-based data analyses [25], examining how [PERSON]'s disease affects coordinated hand-eye movement and corrective response control during grasping movements of virtual objects, using augmented reality and 3D games to encourage patients with [PERSON]'s disease and stroke to perform repetitive exercises near their physical limits in a safe environment [26]. The second topic consists of studies, approaches, and proposals on neurodegenerative diseases using immersive and modern technologies.
