Rehab Games as Components of Workflow: A Case Study

Personalized Virtual Reality Environments for Intervention with People with Disability

Background: Virtual reality (VR) is a technological resource that allows the generation of an environment of great realism while achieving user immersion. The purpose of this project is to use VR as a complementary tool in the rehabilitation process of people with physical and cognitive disabilities. An approach based on performing activities of daily living is proposed. Methods: Through joint work between health and IT professionals, the VR scenarios and skills to be trained are defined. We organized discussion groups in which health professionals and users with spinal injury, stroke, or cognitive impairment participated. A testing phase was carried out, followed by a qualitative perspective. As materials, Unity was used as a development platform, HTC VIVE as a VR system, and Leap Motion as a hand tracking device and as a means of interacting with the scenarios. Results: A VR application was developed, consisting of four scenarios that allow for practicing different activities of daily living. Three scenarios are focused on hand mobility rehabilitation, while the remaining scenario is intended to work on a cognitive skill related to the identification of elements to perform a task. Conclusions: Performing activities of daily living using VR environments provides an enjoyable, motivating, and safe means of rehabilitation in the daily living process of people with disabilities and is a valuable source of information for healthcare professionals to assess a patient’s evolution.

What Do Stroke Patients Look for in Game-Based Rehabilitation: A Survey Study

Stroke is one of the most common causes of physical disability, and early, intensive, and repetitive rehabilitation exercises are crucial to the recovery of stroke survivors. Unfortunately, research shows that only one third of stroke patients actually perform recommended exercises at home, because of the repetitive and mundane nature of conventional rehabilitation exercises. Thus, to motivate stroke survivors to engage in monotonous rehabilitation is a significant issue in the therapy process. Game-based rehabilitation systems have the potential to encourage patients continuing rehabilitation exercises at home. However, these systems are still rarely adopted at patients' places. Discovering and eliminating the obstacles in promoting game-based rehabilitation at home is therefore essential. For this purpose, we conducted a study to collect and analyze the opinions and expectations of stroke patients and clinical therapists. The study is composed of 2 parts: Rehab-preference survey - interviews to both patients and therapists to understand the current practices, challenges, and expectations on game-based rehabilitation systems; and Rehab-compatibility survey - a gaming experiment with therapists to elaborate what commercial games are compatible with rehabilitation. The study is conducted with 30 outpatients with stroke and 19 occupational therapists from 2 rehabilitation centers in Taiwan. Our surveys show that game-based rehabilitation systems can turn the rehabilitation exercises more appealing and provide personalized motivation for various stroke patients. Patients prefer to perform rehabilitation exercises with more diverse and fun games, and need cost-effective rehabilitation systems, which are often built on commodity hardware. Our study also sheds light on incorporating the existing design-for-fun games into rehabilitation system. We envision the results are helpful in developing a platform which enables rehab-compatible (i.e., existing, appropriately selected) games to be operated on commodity hardware and brings cost-effective rehabilitation systems to more and more patients' home for long-term recovery.
