Stroke patients have reduced kinematic characteristics in gait speed, cadence, step kinematics, and range of motion (ROM). Especially, a drop foot is a common symptom during gait after stroke due to the weakness of ankle dorsiflexor. A few robotic ankle systems have been developed to measure and train pathological ankle movements. However, the previously developed systems use orthogonal ankle axis...
We address the problem of online relative orientation estimation from streaming video captured by a sky-facing camera on a mobile device. Namely, we rely on the detection and tracking of visual features attained from cloud structures. Our proposed method achieves robust and efficient operation by combining realtime visual odometry modules, learning based feature classification, and Kalman filtering...
We investigated a virtual reality (VR) proprioceptive rehabilitation system that could manipulate the visual feedback of upper-limb during training and could do training by relying on proprioception feedback only. Virtual environments were designed in order to switch visual feedback on/off during upper-limb training. Two types of VR training tasks were designed for evaluating the effect of the proprioception...
Expressions are a basic necessity for daily living, as they are required for managing relationships with other people. Conventional expression training has difficulty achieving an objective measurement, because their assessment depends on the therapist's ability to assess a patient's state or training effectiveness. In addition, it is difficult to provide emotional and social situations in the same...
In this study, we confirmed proprioception training effect of patients with hemiplegia by manipulating visual feedback. Six patients with hemiplegia were participated in the experiment. Patients have trained with the reaching task with visual feedback without visual feedback for two weeks. Patients were evaluated with pre-, middle test and post-test with the task with and without visual feedback....
Purposes of this paper are developing Virtual Reality rehabilitation system for hemiplegic patients who have stiff-knee gait and testing developed system. We developed rehabilitation system which is able to interact between system using PC camera and two markers. Scenario was composed simple task as crossing stepping-stone. In this paper, six males and three females with hemiplegic patients were participated...
