Our goal is to develop a tool for the assessment and rehabilitation of executive functions by customizing a virtual reality VR system. The specific objective of this study was to conduct a pilot study using a virtual version of the Multiple Errand Test (VMET) in a healthy population. Results are presented which provide support for the feasibility of using the VMET for a subsequent randomized clinical trial.

The application of virtual reality in rehabilitation has led to a rapid development of game-like applications. Since the key concept to successful rehabilitation involves the constant repetition of a task that involves the affected part of the body, such applications motivate patients to practice movements over and over again. Driven gait orthoses provide an excellent tool to use such methods for gait training in a meaningful way. In the present paper we give a first impression of how such an application may look like for the driven gait orthosis Lokomat. With a preliminary study we furthermore show, that such applications not only lead to higher motivation during training but also increase the activity of the patient. All patients report to prefer this new way of feedback and want to use it in subsequent training sessions.

To review the outcomes of rehabilitation for a service member with bilateral lower extremity amputations. A 25 year-old marine suffered a right knee disarticulation and a left transtibial amputation during military service. For two years, the patient underwent a comprehensive rehabilitation program at Walter Reed Army Medical Center. During the course of his rehabilitation, this patient took part in conventional physical therapy and at 16.5 months post-injury added clinical sessions in the Computer Assisted Rehabilitation Environment (CAREN) Laboratory to his therapy regimen for approximately six months. Gait analyses were conducted at three different points in his rehabilitation program: 5.5, 18, and 23.5 months post-injury. Temporal spatial parameters of self-selected velocities, cadence, and step length increased while his stance support time and step width decreased, becoming closer to asymptomatic populations. During the CAREN clinical sessions, the patient showed an increase in overall speed in the Road with Overhead Targets application. With the Boat application, the patient was able to improve the application time at increased levels of difficulty. The use of virtual reality as an adjunct to conventional rehabilitation for individuals with amputations provides a novel approach for maximizing function.

The use of breathing exercises post surgery can reduce pulmonary complications. Incentive spirometry is a widely used device that provides visual feedback for patients during breathing exercises. This paper describes the initial development of an interaction device, game design and initial playtesting and usability of a game to motivate patients to perform post operative breathing exercises.

This study investigated the effects of Virtual Reality Immersion (VRI) as compared with Audio-Visual Distraction (AVD) on the self reported intensity, quality and reactions to severe itching episodes and the associated discomfort, in patients suffering from atopic dermatitis and pruritus. The study suggested that VRI and AVD may be useful non-pharmacological adjunct in reducing itching and discomfort.

How specific are postural and balance control skills? An important issue for the establishment of effective training and retraining (rehabilitation) programs is whether skills gained while training in laboratory settings can be transferred to performance gains in somewhat different conditions (including every-day life). While there is much evidence showing that for volitional motor tasks the gains in performance (procedural, implicit, knowledge) accrued in practice may not always be transferable to novel task conditions, it is not clear whether the (implicit) knowledge gained in learning postural adjustments can be transferred to measures of balance (reaction to external perturbations) that have not been trained. The objective of the current study was to elucidate what aspects of a postural skill learned within a virtual environment (VE) by healthy adults may be transferable to the performance of standard tests of postural adjustments. Sixteen healthy young adults, aged 20–40 years (mean α SD = 29.8 α 2.8 years), were pseudo-randomly assigned to either a training group (Group A) or a no-training, control group (Group B). Group A performed a single training session in a VE in which maintenance of stability on a platform, while travelling along a road scenario and reaching for visual targets (secondary task) were required. Each participant underwent 8 consecutive runs of the task (2:48 m per run). A balance assessment with a given set of perturbations was performed before and after training as well as at 24 hours and 4 weeks post-training. Group B underwent the same assessments but without VE training. The results showed that the Center of Pressure (CoP) displacement tended to decrease over successive balance assessments in both groups, however, this decrease was not statistically significant. Moreover, there was no clear advantage for Group A. Thus, the postural adjustment gains were not transferred to the balance assessment tests. Non-volitional balance control gains are, in this respect, similar to gains attained in a volitional manual task learning.

As part of a larger study evaluating the effects of trunk restraint on the kinematics of arm movements in children with cerebral palsy (CP), we evaluated the level of cooperation and satisfaction of the children when practicing arm and hand movements during play-like activities in a physical environment (PE) compared to a video-capture based (IREX, GestureTek) virtual environment (VE) using 5-point Likert scales. While cooperation was similar in both environments, children expressed greater satisfaction with the PE compared to the VE (p ≪ 0.04). Reasons for this may include difficulty or frustration with the VE activities and/or appropriateness of the computer games.

The Nintendo wiimote sends 22 byte data packets to the Wii console over a blue tooth wireless channel at a typical rate of 100 packets per second. The wiimote wireless channel can be made to carry arbitrary digitized analog data via an I2C serial expansion port. The nunchuck I2C accessory unit provides a convenient five channel input port for analog data. One simply substitutes their signals for any of two channels of joystick axes and three axes of accelerometry which are part of the standard nunchuck configuration. This research describes customizing the low-cost and widely-available wiimote to be used to transmit relevant physiological data from stroke patients while they perform therapy exercises. An example is grip pressure or finger force from a handle while they are exercising in a virtual environment presented on a computer screen. This wiimote wireless data acquisition subsystem may be adequate to achieve a low-cost therapy oriented data system for the hand.
