“…The average completion-time ( Figure 4A) was 195 s (range: 116-320 s); the two less impaired patients (PT0 and PT4) were able to complete the game faster with an average of 147 s (Figure 4). In an earlier study with healthy participants [4], an average of 136 s was obtained. By contrast, our patients performed slightly slower.…”

“…The fooling of healthy participants into believing that their right hand, displayed on the left side of the screen, is their left hand was extensively evaluated [2,3]. In addition, augmentation with virtual backgrounds or 3D models using the ART system was previously evaluated [4]. Yet another manipulation possibility is the spatial manipulation of the displayed hand by the therapist or operator, which allowed changing the position of the user's hand vertically or horizontally, in addition to the user's own movement [4].…”

This paper evaluates the patient engagement and clinical feasibility of an Augmented Reflection Technology (ART) system for use in physical rehabilitation of the upper limb following stroke. In particular, TheraMem, an extension of the ART system, was assessed on its potential to engage patients in meaningful therapeutic exercise. Six patients participated in a total of 24 sessions of upper limb training using the system. Tailored support for patients performing the exercises was provided based on the severity and level of their impairment. Various configurations of the system were evaluated and adjusted to best match the therapeutic requirements and the patient's preferences. All patients were able to successfully participate and complete the TheraMem intervention at a high level of engagement and motivation over the course of the therapy sessions.

Mirror Box therapy is used for rehabilitating stroke patients who have lost control of a hand. The therapy uses mirrors to give patients the illusion that movements of their healthy hand are movements of their impaired hand. The goal of this stimulation is to enable the healthy part of the brain to learn to control the impaired hand. In this paper we present a mirror therapy tool developed using the Kinect motion sensor. We evaluate five different finger tracking SDKs using a controlled environment resembling a clinical setup. The strengths and weaknesses of each SDK are discussed and compared in a trade-off matrix which attempts to quantify the individual performances. We present some algorithmic improvements to hand and finger tracking, explain how this information is used to control a skeletally animated hand, and present a simple game to make exercises more enjoyable. We evaluate our application and identify shortcomings of the presented technique.

“…Therefore, when patient looks into the mirror, he/she will see the reflection of the unaffected arm as his/her impaired arm by creating the visual illusion. This approach has been used to treat the patients suffering from phantom limb pain (PLP) [11,12], complex regional pain syndrome (CRPS) [12,13] and stroke [12,14]. Integrating visual illusion provides fast recovery in rehabilitation due to human neuroplasticity ability which is mediated by beliefs, perceptions and emotions that react in everchanging ways, through thoughts and activities based on environmental input.…”

This paper presents design and development of real time biosignal-driven illusion system: Augmented Reality based Illusion System (ARIS) for upper limb motor rehabilitation. ARIS is a hospital / home based selfmotivated whole arm rehabilitation system that aims to improve and restore the lost upper limb functions due to Cerebrovascular Accident (CVA) or stroke. Taking the advantage of human brain plasticity nature, the system incorporates with number of technologies to provide fast recovery by re-establishing the neural pathways and synapses that able to control the mobility. These technologies include Augmented Reality (AR) where illusion environment is developed, computer vision technology to track multiple colors in real time, EMG acquisition system to detect the user intention in real time and 3D modelling library to develop Virtual Arm (VA) model where human biomechanics are applied to mimic the movement of real arm. The system operates according to the user intention via surface electromyography (sEMG) threshold level. In the case of real arm cannot reach to the desired position, VA will take over the job of real arm to complete the exercise. The effectiveness of the developed ARIS has evaluated via questionnaire, graphical and analytical measurements which provided with positive results.
