Patients with stroke usually have disabilities related to motor impairments due to incomplete motor recovery. Such disabilities, lengthy travel time to a clinic, or socioeconomic difficulties can hinder patients&#39; access to adequate rehabilitation therapy. A ubiquitous healthcare (u-Health) program can be a good option for removing those barriers. As a part of such a u-Health program, a mobile game-based VR rehabilitation program was developed for upper limb recovery after ischemic stroke in the present study. Our fin...

Stroke is one of the most common causes of neurological impairment in adults. Recovery from impairment after a stroke is usually incomplete, and approximately 50% of patients are left with disabilities, making them dependent on others1. In particular, upper limb dysfunction makes stroke survivors dependent on others for assistance with activities of daily living (ADL)2. Regaining the lost function in the upper extremities may be more difficult to achieve than returning the normal function of ambulation to the lower extremities. Although bilateral lower extremity movement is indispensable for locomotion, patients can perform ADL with unilateral upper extremity movement. This leads to a learned non-use phenomenon of the affected limb3. This phenomenon is an obstacle to the rehabilitation of the upper extremity in stroke survivors. Therefore, a tremendous amount of research is focused on the upper limb function recovery. Studies have highlighted the importance of extensive practice and repetitive task-specific training4,5,6.
Virtual reality (VR) technology has recently been introduced into the field of rehabilitation7. VR allows users to interact with a simulated environment and receive continuous, immediate feedback related to performance. VR has the potential to apply basic concepts of neurorehabilitation in stroke patients, such as intensive, repetitive, and task-oriented training8. Specifically, non-immersive VR does not require high-level graphics performance or special hardware. Therefore, non-immersive VR is a good candidate for providing a low-cost, ubiquitous, and interesting treatment program. Previous studies used computers, monitors, and special devices, such as consoles, sensor gloves, joy-sticks, and commercial gaming systems for non-immersive VR9. Higher start-up costs and sufficient space were mandatory for using such systems. Recently, low-cost tools, such as commercial gaming devices, have been utilized to develop new rehabilitation systems10,11. However, the consoles with sensors in those devicesare not sufficiently small and lightweight for carrying. Nevertheless, to improve the popularity of non-immersive VR as a post-stroke upper extremity treatment method and to create a ubiquitous rehabilitation environment for stroke survivors, portable and inexpensive tools are needed.
Furthermore, game-based therapy can be a good option for stroke rehabilitation. Many patients complain that conventional occupational therapy (OT) for upper limb function recovery is boring and monotonous12,13. A more interesting and motivating tool for the therapy is, therefore, necessary to promote patients&#39; engagement in rehabilitation training. Many studies that involve the use of commercial games have been conducted14,15,16. However, the games used do not target the desired movement of the upper extremity in patients with stroke, and they lack special consideration for the spasticity that may be present after a stroke.
This paper describes the development of a mobile game-based VR program and its use for patients who have experienced a stroke and suffer from upper limb dysfunction (Figure 1).

mobile game-based virtual reality program for upper extremity stroke rehabilitation

Stroke rehabilitation requires repetitive, intensive, goal-oriented therapy. Virtual reality (VR) has the potential to satisfy these requirements. Game-based therapy can promote patients&#39; engagement in rehabilitation therapy as a more interesting and a motivating tool. Mobile devices such as smartphones and tablet PCs can provide personalized home-based therapy with interactive communication between patients and clinicians. In this study, a mobile VR upper extremity rehabilitation program using game applications was developed. The findings from the study show that the mobile game-based VR program effectively promotes upper extremity recovery in patients with stroke. In addition, patients completed two weeks of treatment using the program without adverse effects and were generally satisfied with the program. This mobile game-based VR upper extremity rehabilitation program can substitute for some parts of the conventional therapy that are delivered one-on-one by an occupational therapist. This time-efficient, easy to implement, and clinically effective program would be a good candidate tool for tele-rehabilitation for upper extremity recovery in patients with stroke. Patients and therapists can collaborate remotely through these e-health rehabilitation programs while reducing economic and social costs.

A total of 24 patients were enrolled and assigned to either the control or the experimental group (Table 1). A greater improvement in the FMA-UE, B-stage, and manual muscle testing was found after treatment with the mobile game-based VR upper extremity rehabilitation program than with conventional therapy (Figure 3). The effect was maintained until the one-month follow-up. This means MoU-Rehab was not inferior to the conventional therapy that...

Mobile Game-based Virtual Reality Program for Upper Extremity Stroke Rehabilitation

Here, we present a protocol to develop and apply a mobile game-based virtual reality program for the recovery of upper limb dysfunction in patients with stroke. The present study shows that the mobile program is feasible and effectively promotes upper limb recovery in stroke patients.

Stroke rehabilitation requires repetitive, intensive, goal-oriented therapy. Virtual reality (VR) has the potential to satisfy these requirements. ...

The overall goal of this program is to provide a mobile game-based upper extremity virtual reality program using a combination of two mobile devices, a smartphone and tablet PC, for patients with stroke. This method can help answer key questions in the u-healthcare field regarding home-based telerehabilitation. The main advantage of this technique is that mobile game-based upper extremity virtual reality programs can provide an inexpensive, ubiquitous, motivating, and interesting treatment for stroke patients.The implications of this technique centers toward rehabilitation therapy because a mobile game-based upper extremity program can solve the problems faced by patients who have difficulty traveling to a clinic due to transportation, time, cost, or stroke impairment. Begin by escorting the participant into the therapy room, and have them sit at the desk. Place the tablet PC on the desk, and turn it on.Next, turn on the smartphone, as well as the short-distance wireless connection on the smartphone. Choose the game application on the tablet by touching the screen. Then, put the smartphone in the armband, and attach the armband to the upper arm or forearm of the participant, depending on the desired movement.Choose either the basic or the customized version of the game. Then, according to the participant's ability, select the game speed, time, a number of target movements, and the expected achievement of the game on the touchscreen of the tablet PC on the customized version. Instruct the participant to move their body according to the commands of the game, allowing the maximal range of motion for calibration.Then, have them press the start button to begin. Track the participant's upper extremity movements using the built-in sensors of the smartphone, and transfer information about the movement to the tablet PC through the short-distance wireless connection. Provide visual and auditory feedback for the participant on their movement with the display on the tablet PC.Demonstrate the real achievement of the game as compared with the expected achievement at the end of the game.Finally, observe the participant playing the game. For the Honey Pot Guard game, begin by asking the participant to beat a bear from the honey pot by throwing apples using the movement of the elbow joint. Let the participant throw apples when the flexed elbow is extended.Next, for the Protect the Bunny game, ask the participant to protect the bunny by catching stones with the net using the movement of the shoulder joint. Ensure that the net moves when the adducted shoulder is abducted. Following that, for the Put Out Fire game, ask the participant to put the fire out with the water hose through the window, which is controlled via the motion of the shoulder.Ensure that the water hose moves right and left and up and down corresponding to the motion of the shoulder joint. Lastly, for the Flower Splash game, have the participant use their joint motion to water the moving seed with a watering can and make the flowers blossom. A greater improvement in the Fugl-Meyer Assessment of the upper extremity, Brunnstrom stage, and manual muscle testing was found after treatment with the mobile game-based VR upper extremity rehabilitation program than with conventional therapy.Participants in the experimental group completed the two-week treatment without adverse effects and were generally satisfied based on the provided questionnaire, even though participants had various levels of technology familiarity. While attempting this procedure, it is important to remember to target the desired movement of the upper extremity with special consideration for accompanying problems related to stroke, such as hemiplegic shoulder pain and spasticity. Don't forget that working with this program in a home setting requires monitoring a patient's adherence to the program, and continuous, immediate feedback related to performance should be given to increase interest in motivation in rehabilitation therapy.After its development, this technique paved the way for researchers in the field of rehabilitation by exploring the efficacy and feasibility of a mobile rehabilitation program for the recovery of upper limb function in patients with stroke. After watching this video, you should have a good understanding of how to design and deliver a mobile rehabilitation program. that is, increase the hours of repetitive, goal-oriented therapy without increasing costly therapy time or requiring expensive equipment.

Two-photon Calcium Imaging in Mice Navigating a Virtual Reality Environment

In recent years, two-photon imaging has become an invaluable tool in neuroscience, as it allows for chronic measurement of the activity of genetically identified cells during behavior1-6. Here we describe methods to perform two-photon imaging in mouse cortex while the animal navigates a virtual reality environment. We focus on the aspects of the experimental procedures that are key to imaging in a behaving animal in a brightly lit virtual environment. The key problems that arise in this experimental setup that we here address are: minimizing brain motion related artifacts, minimizing light leak from the virtual reality projection system, and minimizing laser induced tissue damage. We also provide sample software to control the virtual reality environment and to do pupil tracking. With these procedures and resources it should be possible to convert a conventional two-photon microscope for use in behaving mice.

Here we describe the experimental procedures involved in two-photon imaging of mouse cortex during behavior in a virtual reality environment.

Development of a Virtual Reality Assessment of Everyday Living Skills

Cognitive impairments affect the majority of patients with schizophrenia and these impairments predict poor long term psychosocial outcomes.&#160; Treatment studies aimed at cognitive impairment in patients with schizophrenia not only require demonstration of improvements on cognitive tests, but also evidence that any cognitive changes lead to clinically meaningful improvements.&#160; Measures of &#8220;functional capacity&#8221; index the extent to which individuals have the potential to perform skills required for real world functioning. &#160;Current data do not support the recommendation of any single instrument for measurement of functional capacity.&#160; The Virtual Reality Functional Capacity Assessment Tool (VRFCAT) is a novel, interactive gaming based measure of functional capacity that uses a realistic simulated environment to recreate routine activities of daily living. Studies are currently underway to evaluate and establish the VRFCAT&#8217;s sensitivity, reliability, validity, and practicality.&#160;This new measure of functional capacity is practical, relevant, easy to use, and has several features that improve validity and sensitivity of measurement of function in clinical trials of patients with CNS disorders.

A challenge for proving treatment efficacy for cognitive impairments in schizophrenia is finding the optimizing measurement of skills related to everyday functioning.&#160; The Virtual Reality Functional Capacity Assessment Tool (VRFCAT) is an interactive gaming based computerized measure aimed at skills associated with everyday functioning, including baseline impairments and treatment related changes.

Multifunctional Setup for Studying Human Motor Control Using Transcranial Magnetic Stimulation, Electromyography, Motion Capture, and Virtual Reality

The study of neuromuscular control of movement in humans is accomplished with numerous technologies. Non-invasive methods for investigating neuromuscular function include transcranial magnetic stimulation, electromyography, and three-dimensional motion capture. The advent of readily available and cost-effective virtual reality solutions has expanded the capabilities of researchers in recreating &#8220;real-world&#8221; environments and movements in a laboratory setting. Naturalistic movement analysis will not only garner a greater understanding of motor control in healthy individuals, but also permit the design of experiments and rehabilitation strategies that target specific motor impairments (e.g. stroke). The combined use of these tools will lead to increasingly deeper understanding of neural mechanisms of motor control. A key requirement when combining these data acquisition systems is fine temporal correspondence between the various data streams. This protocol describes a multifunctional system&#8217;s overall connectivity, intersystem signaling, and the temporal synchronization of recorded data. Synchronization of the component systems is primarily accomplished through the use of a customizable circuit, readily made with off the shelf components and minimal electronics assembly skills.

Transcranial magnetic stimulation, electromyography, and 3D motion capture are commonly used non-invasive techniques for investigating neuromuscular function in humans. In this paper, we describe a protocol that synchronously samples data generated by all three of these tools along with the unique addition of virtual reality stimulus presentation and feedback.

A Structured Rehabilitation Protocol for Improved Multifunctional Prosthetic Control: A Case Study

Advances in robotic systems have resulted in prostheses for the upper limb that can produce multifunctional movements. However, these sophisticated systems require upper limb amputees to learn complex control schemes. Humans have the ability to learn new movements through imitation and other learning strategies. This protocol describes a structured rehabilitation method, which includes imitation, repetition, and reinforcement learning, and aims to assess if this method can improve multifunctional prosthetic control. A left below elbow amputee, with 4 years of experience in prosthetic use, took part in this case study. The prosthesis used was a Michelangelo hand with wrist rotation, and the added features of wrist flexion and extension, which allowed more combinations of hand movements. The participant&#8217;s Southampton Hand Assessment Procedure score improved from 58 to 71 following structured training. This suggests that a structured training protocol of imitation, repetition and reinforcement may have a role in learning to control a new prosthetic hand. A larger clinical study is however required to support these findings.

As prosthetic development moves towards the goal of natural control, harnessing amputees&#8217; inherent ability to learn new motor skills may enable proficiency. This manuscript describes a structured rehabilitation protocol, which includes imitation, repetition, and reinforcement learning strategies, for improved multifunctional prosthetic control.

Using Virtual Reality to Transfer Motor Skill Knowledge from One Hand to Another

As far as acquiring motor skills is concerned, training by voluntary physical movement is superior to all other forms of training (e.g. training by observation or passive movement of trainee&#39;s hands by a robotic device). This obviously presents a major challenge in the rehabilitation of a paretic limb since voluntary control of physical movement is limited. Here, we describe a novel training scheme we have developed that has the potential to circumvent this major challenge. We exploited the voluntary control of one hand and provided real-time movement-based manipulated sensory feedback as if the other hand is moving. Visual manipulation through virtual reality (VR) was combined with a device that yokes left-hand fingers to passively follow right-hand voluntary finger movements. In healthy subjects, we demonstrate enhanced within-session performance gains of a limb in the absence of voluntary physical training. Results in healthy subjects suggest that training with the unique VR setup might also be beneficial for patients with upper limb hemiparesis by exploiting the voluntary control of their healthy hand to improve rehabilitation of their affected hand.

We describe a novel virtual-reality based setup which exploits voluntary control of one hand to improve motor-skill performance in the other (non-trained) hand. This is achieved by providing real-time movement-based sensory feedback as if the non-trained hand is moving. This new approach may be used to enhance rehabilitation of patients with unilateral hemiparesis.

Paradigms of Lower Extremity Electrical Stimulation Training After Spinal Cord Injury

Skeletal muscle atrophy, increased adiposity and reduced physical activity are key changes observed after spinal cord injury (SCI) and are associated with numerous cardiometabolic health consequences. These changes are likely to increase the risk of developing chronic secondary conditions and impact the quality of life in persons with SCI. Surface neuromuscular electrical stimulation evoked resistance training (NMES-RT) was developed as a strategy to attenuate the process of skeletal muscle atrophy, decrease ectopic adiposity, improve insulin sensitivity and enhance mitochondrial capacity. However, NMES-RT is limited to only a single muscle group. Involving multiple muscle groups of the lower extremities may maximize the health benefits of training. Functional electrical stimulation-lower extremity cycling (FES-LEC) allows for the activation of 6 muscle groups, which is likely to evoke greater metabolic and cardiovascular adaptation. Appropriate knowledge of the stimulation parameters is key to maximizing the outcomes of electrical stimulation training in persons with SCI. Adopting strategies for long-term use of NMES-RT and FES-LEC during rehabilitation may maintain the integrity of the musculoskeletal system, a pre-requisite for clinical trials aiming to restore walking after injury. The current manuscript presents a combined protocol using NMES-RT prior to FES-LEC. We hypothesize that muscles conditioned for 12 weeks prior to cycling will be capable of generating greater power, cycle against higher resistance and result in greater adaptation in persons with SCI.

Spinal cord injury is a traumatic medical condition that may result in elevated risks of chronic secondary metabolic disorders. Here, we presented a protocol using surface neuromuscular electrical stimulation-resistance training in conjunction with functional electrical stimulation-lower extremities cycling as a strategy to ameliorate several of these medical problems.

Measuring the Kinematics of Daily Living Movements with Motion Capture Systems in Virtual Reality

The inability to complete instrumental activities of daily living (IADL) is a precursor to various neuropsychological diseases. Questionnaire-based assessments of IADL are easy to use but prone to subjective bias. Here, we describe a novel virtual reality (VR) test to assess two complex IADL tasks: handling financial transactions and using public transportation. While a participant performs the tasks in a VR setting, a motion capture system traces the position and orientation of the dominant hand and head in a three-dimensional Cartesian coordinate system. Kinematic raw data are collected and converted into &#39;kinematic performance measures,&#39; i.e., motion trajectory, moving distance, and time to completion. Motion trajectory is the path of a particular body part (e.g., dominant hand or head) in space. Moving distance refers to the total distance of the trajectory, and time to completion is how long it took to complete an IADL task. These kinematic measures could discriminate patients with cognitive impairment from healthy controls. The development of this kinematic measuring protocol allows detection of early IADL-related cognitive impairments.

We designed a virtual reality test to assess instrumental activities of daily living (IADL) with a motion capture system. We propose a detailed kinematic analysis to interpret the participant&#39;s various movements, including trajectory, moving distance, and time to completion to evaluate IADL capabilities.

A Networked Desktop Virtual Reality Setup for Decision Science and Navigation Experiments with Multiple Participants

Investigating the interactions among multiple participants is a challenge for researchers from various disciplines, including the decision sciences and spatial cognition. With a local area network and dedicated software platform, experimenters can efficiently monitor the behavior of the participants that are simultaneously immersed in a desktop virtual environment and digitalize the collected data. These capabilities allow for experimental designs in spatial cognition and navigation research that would be difficult (if not impossible) to conduct in the real world. Possible experimental variations include stress during an evacuation, cooperative and competitive search tasks, and other contextual factors that may influence emergent crowd behavior. However, such a laboratory requires maintenance and strict protocols for data collection in a controlled setting. While the external validity of laboratory studies with human participants is sometimes questioned, a number of recent papers suggest that the correspondence between real and virtual environments may be sufficient for studying social behavior in terms of trajectories, hesitations, and spatial decisions. In this article, we describe a method for conducting experiments on decision-making and navigation with up to 36 participants in a networked desktop virtual reality setup (i.e., the Decision Science Laboratory or DeSciL). This experiment protocol can be adapted and applied by other researchers in order to set up a networked desktop virtual reality laboratory.

This paper describes a method for conducting multi-user experiments on decision-making and navigation using a networked computer laboratory.

Investigating the interactions among multiple participants is a challenge for researchers from various disciplines, including the decision sciences and ...

Virtual Reality Experiments with Physiological Measures

Virtual reality (VR) experiments are increasingly employed because of their internal and external validity compared to real-world observation and laboratory experiments, respectively. VR is especially useful for geographic visualizations and investigations of spatial behavior. In spatial behavior research, VR provides a platform for studying the relationship between navigation and physiological measures (e.g., skin conductance, heart rate, blood pressure). Specifically, physiological measures allow researchers to address novel questions and constrain previous theories of spatial abilities, strategies, and performance. For example, individual differences in navigation performance may be explained by the extent to which changes in arousal mediate the effects of task difficulty. However, the complexities in the design and implementation of VR experiments can distract experimenters from their primary research goals and introduce irregularities in data collection and analysis. To address these challenges, the Experiments in Virtual Environments (EVE) framework includes standardized modules such as participant training with the control interface, data collection using questionnaires, the synchronization of physiological measurements, and data storage. EVE also provides the necessary infrastructure for data management, visualization, and evaluation. The present paper describes a protocol that employs the EVE framework to conduct navigation experiments in VR with physiological sensors. The protocol lists the steps necessary for recruiting participants, attaching the physiological sensors, administering the experiment using EVE, and assessing the collected data with EVE evaluation tools. Overall, this protocol will facilitate future research by streamlining the design and implementation of VR experiments with physiological sensors.

Virtual reality (VR) experiments can be difficult to implement and require meticulous planning. This protocol describes a method for the design and implementation of VR experiments that collect physiological data from human participants. The Experiments in Virtual Environments (EVE) framework is employed to accelerate this process.

A Novel Digital Platform for a Monitored Home-based Cardiac Rehabilitation Program

Despite the evidence that cardiac rehabilitation (CR) reduces the risk of recurrent cardiac events, only a minority of eligible patients are willing to join existing programs at cardiac rehabilitation centers. The unique remote patient monitoring system presented here enables healthcare providers to monitor CR patients at home in real-time and at low cost. The system combines mobile technology, artificial intelligence, and supportive services, expanding the delivery of medical care to the patient&#39;s home. The primary aim of the study is to increase the long-term adherence to physical activity in patients who participate in CR via the addition of a home-based digitally monitored CR component to the standard CR program in patients with ischemic heart disease (IHD), with the idea of forming new habitual health behaviors and increasing the long-term motivation for physical exercise (PE) habits at home. Secondary aims are to assess the program&#39;s impact on the physical activity level measured by average steps per day, minutes of exercise per week, blood pressure, metabolic parameters, body mass index, and waist-to-hip ratio, as well as a quality-of-life (QoL) questionnaire.The study has two arms: (1) home-based monitored exercise using a smart digital garment and wristband, in addition to motivation and reinforcement via text messages; (2) standard CR facility-based exercise. The study design is a randomized, controlled trial comparing standard CR to a home-based monitoring and reinforcement program. The study program is designed for 12 weeks.Clinical tests and anthropometric measurements are performed before and after the study, measuring height, weight, waist circumference, visceral fat and body mass index (BMI), blood pressure, and HbA1c and lipid profile. Patients have to complete a baseline survey including socio-demographic characteristics and QoL questionnaire SF-36. At the end of the study, patients complete a survey regarding the use of the smart digital garment&#39;s benefits and usability. The study is currently underway.

The aim is to promote a new approach to cardiac rehabilitation (CR), using a unique remote patient monitoring system that will enable healthcare providers to monitor CR patients at home at low cost, with the intention of making CR services more accessible and improving compliance. The study is currently underway.
