Article

Stroke is a leading cause of long-term disability, and virtual reality- (VR-) based stroke rehabilitation is effective in increasing motivation and the functional performance. Although much of the functional reach and grasp capabilities of the upper extremities were regained, the pinch movement remains impaired following stroke. In this study, we d...
Article
Falls are costly, affect independence, and are a leading cause of injury in adults over the age of 65. Awareness of fall risk and engaging with healthcare systems prior to the first fall, annual visit, or hospital stay could have a significant impact on quality of life and healthcare costs. Clinicians use the FRQ, 30STST, and OLST to measure balanc...

Objective: To compare phase- and task-dependent H-reflex modulation in standing and walking in 2 spinal cord injury (SCI) groups with and without a walker. Methods: Fourteen subjects with American Spinal Injury Association Impairment Scale D SCI (40±10 years) participated. Tibial nerve was stimulated to evoke 15 H-reflexes (at M-wave 7%-13% of maxi...
Conference Paper
In this paper a novel augmented-reality environment is presented for enhancing locomotor training. The main goal of this environment is to excite kids for walking and hence facilitate their locomotor therapy and at the same time provide the therapist with a quantitative framework for monitoring and evaluating the progress of the therapy. This paper...
Conference Paper
Full-text available
We describe a pilot clinical trial with a flexible telerehabilitation platform that allows a therapist to remotely monitor the exercise regimen and progress of a patient who previously suffered from a stroke. We developed virtual game environments which were host to a progressive set of training tasks from precise fine motor movements to reaching m...

Full-text available
More than one-third of people over the age of 65 experience falls each year, and those who fall once are two to three times more likely to fall again. A fall can significantly limit a person's ability to remain self-sufficient. Fall injuries are responsible for significant disability, reduced physical function, and loss of independence. However, fa...
Article
Conventional physical therapy techniques have been shown to improve balance, mobility, and gait following neurological injury. Treatment involves training patients to transfer weight onto the impaired limb to improve weight shift while standing and walking. Visual biofeedback and force plate systems are often used for treatment of balance and mobil...
Article
Full-text available
Using the advances in computing power, software and hardware technologies, virtual reality (VR), and gaming applications have the potential to address clinical challenges for a range of disabilities. VR-based games can potentially provide the ability to assess and augment cognitive and motor rehabilitation under a range of stimulus conditions that...
Article
Full-text available
Aims/background: Off-the-shelf games for consoles such as the Nintendo Wii, Nintendo WiiFit and Sony PlayStation 2 EyeToy have been developed and tested for the purpose of entertainment. Many clinics are adopting the use of these off-the-shelf devices for exercise, social interaction and rehabilitation because they are affordable, accessible and ca...
Conference Paper
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...
Article
To examine paired reflex depression changes post 20-minute bout each of 2 training environments: stationary bicycle ergometer training (bicycle training) and treadmill with body weight support and manual assistance (locomotor training). Pretest-posttest repeated-measures. Locomotor laboratory. Motor incomplete SCI (n=12; mean, 44+/-16y); noninjured...
Article
This paper describes the use of Virtual Reality in four projects within a Rehabilitation Engineering Research Center at the University of Southern California. The Research Center aims to develop and assess a range of technologies for people aging with and into a disability. One of the deliverables of this Center will be the development of a Virtual...
Article
Full-text available
This article summarizes the recent accomplishments and current challenges facing game-based virtual reality (VR) telerehabilitation. Specifically this article addresses accomplishments relative to realistic practice scenarios, part to whole practice, objective measurement of performance and progress, motivation, low cost, interaction devices and ga...
Article
Incomplete spinal cord injury (ISCI) frequently disrupts afferent and efferent neural pathways underlying co-requisite voluntary and involuntary muscle activation required for functional standing and walking. To understand involuntary postural control mechanisms necessary for standing, we compared eight individuals with ISCI to eight controls with...
Article
Many Americans live with physical functional limitations stemming from stroke. These functional limitations can be reduced by task-specific training that is repetitive, motivating, and augmented with feedback. Virtual reality (VR) is reported to offer an engaging environment that is repetitive, safe, motivating, and gives task-specific feedback. Th...

Article
To evaluate the effectiveness and validity of the Functional Reach Test (FRT) as a screening tool to identify fallers (persons at risk for falls) among subjects with Parkinson's disease (PD) and control subjects. A case-comparison design with a consecutive sample. Subjects performed 3 consecutive functional reach trials. Motor behavior laboratory i...
Article
The purpose of this study was to assess the effect of a single bout of a locomotor-training paradigm on overground walking speed and H-reflex modulation of individuals with incomplete spinal cord injury (SCI). Self-selected and maximum walking speeds and soleus H-reflexes (H/M ratios) during standing and stance and swing phases of walking (self-sel...
Article
Falls that occur while walking have been associated with an increased risk of hip fracture in elderly people. This study's purpose was to describe movement characteristics in older adults that serve as indicators of difficulty in turning while walking. Three groups were assessed: young adults who had no difficulty in turning (age range=20-30 years,...

This paper will discuss preliminary findings of user preferences regarding video game and VR game-based motor rehabilitation systems within a physical therapy clinic for patients with SCI, TBI and amputation. The video game and VR systems chosen for this research were the Sony PlayStation ® 2 EyeToy ™ , Nintendo ® Wii ™ , and Novint ® Falcon ™ and...
