Impaired motor function is a common consequence of upper motor neuron lesions (UMNLs). Fine motor skills involved in small movements occurring in the fingers, hand and wrist are usually regained by patient self-training at home. Most studies focus on rehabilitation of the fingers but ignore recovery of wrist motor function. In this paper, three virtual guiding tasks were designed to assess wrist motor functions, including the basic motor flexibility, motion stability and a range of active motion. A haptic device was used to provide haptic feedback to users who performed virtual tasks in a virtual reality (VR) environment. In total, 46 healthy subjects and 10 UMNL patients were included to test the effectiveness of the designed tasks on improving wrist motor assessments. Quantitative performances, including the completion time, contact force and motion trajectory, were automatically acquired during the tasks. Measurements for 95% of control subjects were used to establish normative references. Patient deficiencies in wrist motor function were identified when their quantitative performances were outside the normative control ranges. The results suggest that the designed virtual tasks are sensitive for patients in the later period of rehabilitation, making the assessment suitable for using at home.

Increasing presence is one of the primary goals of virtual reality research. A crucial aspect is that users are capable of distinguishing their self from the external virtual world. The hypothesis we ...
Force feedback gloves have found many applications in fields such as teleoperation and virtual reality. In order to enhance the immersive feeling of interaction with remote or virtual environments, gl...
It was suggested that the lack of haptic feedback, formerly considered a limitation for the da Vinci robotic system, does not affect robotic surgeons because of training and compensation based on visu...
Haptic perception is an important modality in reinforcing the presence of virtual or remote targets, but providing haptic feedback of dynamic environments still remains a challenging task. We address ...
The design of human machine interfaces (HMIs) by virtual haptics is an emerging field of research. So far, the perception of virtual haptic feedback, e.g., generated by focused ultrasound in mid-air h...

A mechanism of communication with a physiological system for homeostasis, adaptation, etc. Physiological feedback is mediated through extensive feedback mechanisms that use physiological cues as feedback loop signals to control other systems.
Treatment technique in a virtual environment which allows the participant to experience a sense of presence in an immersive, computer-generated, three-dimensional, interactive environment that minimizes avoidance behavior and facilitates emotional involvement.

An approach, process, or methodology which emphasizes credible evidence and the best available scientific knowledge, judiciously integrated to achieve the best possible outcomes in structural design. For example, the design of a new OUTPATIENT CLINIC might incorporate a review of published research on outpatient clinic design, decisions on similar past projects, along with interviews with staff and consumers.
Classification system for assessing impact injury severity developed and published by the American Association for Automotive Medicine. It is the system of choice for coding single injuries and is the foundation for methods assessing multiple injuries or for assessing cumulative effects of more than one injury. These include Maximum AIS (MAIS), Injury Severity Score (ISS), and Probability of Death Score (PODS).
Architecture, exterior and interior design, and construction of facilities other than hospitals, e.g., dental schools, medical schools, ambulatory care clinics, and specified units of health care facilities. The concept also includes architecture, design, and construction of specialized contained, controlled, or closed research environments including those of space labs and stations.
