The newly blind face enormous emotional, cognitive and physical difficulties in the first stage of rehabilitation. During the traditional orientation and mobility rehabilitation program, the newly blind are trained in basic orientation and mobility skills. The virtual system BlindAid aimed to serve as a simulator for the subject to practice his or her new spatial knowledge and orientation and mobility strategies. The two main goals of this research were to examine: (1) the exploration strategies and process of the newly blind when using a virtual environment; (2) the contribution of the virtual environment exploration process to performance on orientation tasks in virtual environments and real spaces. The findings supply evidence that interaction with the BlindAid system by people who are newly blind provides the participants' development of comprehensive cognitive maps of actual known and unknown spaces during their rehabilitation program.

The aim of this study was to compare users' acceptance and experience through psychological questionnaires for two gaming platforms when used as an exercise tool. Thirty-three participants were recruited from the population of Teesside University, UK. Participants were randomly allocated to either exercise using the Interactive Rehabilitation and Exercise system, or the Nintendo Wii. Following a four-week exercise programme, no significant differences were found between gaming platforms. However, there were significant increases in acceptance and experience.

Virtual environments (VE) are emerging for the creation of effective and motivating exercise therapy for neurorehabilitation of MS and stroke patients. Although these interactive systems are promising tools in rehabilitation, the targeted end users often suffer from visual system disorders and cognitive dysfunctions, which may influence their capabilities while navigating in a virtual 3D world. Cues like shades are proven to be effective navigation and localization aids in a 3D environment for healthy people, but little is known about their benefit for persons with a neurological disease. Therefore, we conducted a user study to test the impact of visual cues such as shading on navigation tasks in a VE for a population of MS and stroke patients. We compared 3 visual conditions in the environment: one without shading, one with shading, and one with shading as well as a dropline between the shade and the object representing the person's location in the environment. Participants in the user study were 11 persons diagnosed with MS, 9 with stroke and 9 healthy control persons. Subjective measures were not uninfluenced by the use of shade or a dropline, but objective measures show a significant increase in speed, and lower execution time resulting from the addition of object-shading.

Spinal cord injury (SCI) causes both lower limb motor dysfunction and associated neuropathic pain. Although these two conditions share related cortical mechanisms, different interventions are currently used to treat each condition. With intensive training using entertaining virtual reality (VR) scenarios, it may be possible to reshape cortical networks thereby reducing neuropathic pain and improving motor function. We have created the first VR training system combining action observation and execution addressing lower limb function in incomplete SCI (iSCI) patients. A particular feature of the system is the use of size-adjustable shoes with integrated motion sensors. A pilot single-case clinical study is currently being conducted on six iSCI patients. Two patients tested to date were highly motivated to perform and reported improved physical well-being. They improved in playing skill and in controlling the virtual lower limbs. There were post-intervention indications of neuropathic pain decrease, muscle strength increase, faster walking speed and improved performance on items relevant for ambulation. In addition functional MRI before and after treatment revealed a decreased activation pattern. We interpret this result as an improvement of neuronal synergies for this task. These results suggest that our VR system may be beneficial for both reducing neuropathic pain and improving motor function in iSCI patients.
