Human motion analysis using artificial vision is an interesting topic in the biomechanical analysis of the human body for rehabilitation routines. The people with motor disorders can achieve better and faster results if a quantitative analysis of patient progress is carried out by precision. Nowadays, there are many systems capable to capture human body movements, however these tools can be invasive,...
Stroke is the main cause of motor and cognitive disabilities requiring therapy in the world. Therefor it is important to develop rehabilitation technology that allows individuals who had suffered a stroke to practice intensive movement training without the expense of an always-present therapist. We have developed a low-cost vision-based system that allows stroke survivors to practice arm movement...
The use of virtual reality technology in the field of amputee rehabilitation is in its earliest stages of development. A virtual environment (VE) will facilitate the early rehabilitation of a patient before they are clinically ready to be fitted with an actual prosthesis. Success will be defined by delivering accurate position and orientation data of the arm to the virtual environment. We have applied...
Generally, the tracking system is one of the main restrictions in a virtual rehabilitation system because of its cost and / or complex setup. Here we introduce the concept of Virtual Reality Motor Cues (VR Motor Cues). VR Motor Cues include those mechanisms designed with the specific purpose of inducing the user to realize a specific motor activity. An effective VR Motor Cue can guarantee, in a high...
VIRCOG is a virtual reality system for the cognitive rehabilitation of patients with neuropsychological disorders (planning, attention, memory, neglect, etc.) in clinical centers. This system allows professionals to offer patients a focused cognitive rehabilitation process to train them to face several activities of daily living (ADL) in a progressive way (difficulty levels), and give them real time...
We investigated the effects of combining the visual and haptic modalities on the adaptation capabilities of healthy subjects to the virtual environment. The haptic feedback was provided by the actuated gait orthosis Lokomat programmed with stepping movements employing an impedance control algorithm. The visual cueing (only the reference motion is presented) and visual feedback (the reference motion...
Stroke is the main cause of disabilities in the world and is typically treated with intensive, hands-on physical and occupational therapy for several weeks after the initial injury. However, due to economic pressures, stroke patients are receiving less therapy and going home sooner, so the potential benefit of the therapy is not completely realized. Thus, it is important to develop rehabilitation...
Stroke is a leading cause of severe physical disability, causing a range of impairments. Frequently stroke survivors are left with partial paralysis on one side of the body and movement can be severely restricted in the affected sidepsilas hand and arm. We know that effective rehabilitation must be early, intensive and repetitive, which leads to the challenge of how to maintain motivation for people...
The proposed demonstration stems from research on a low cost haptic virtual interaction platform for upper-limb rehabilitation. This work centers on the use of vibrotactile feedback in a virtual environment to help stroke patients perform simple repetitive motions and thereby overcome motor planning deficits. The device to be demonstrated consists of a sleeve with embedded optical markers and vibration...
The importance of systematic usability evaluation of virtual rehabilitation systems cannot be underestimated. We have developed a virtual rehabilitation system with the functionality to guide a user through a therapeutic exercise programme. Progression is determined by userspsila ability to replicate movements as demonstrated by an on-screen character. Visual and auditory corrective feedback is provided...
