Transcranial Magnetic Stimulation(TMS) is a noninvasive technique used for treating stroke, Parkinson's disease and depression among others by directly applying magnetic stimulation to the brain. In this system, navigation system that can provide accurate information on location of stimulation is needed for effective TMS because it is critical to stimulate(More)
In this preliminary study, we utilized the Webcam with bigger field of view (FOV) in order to overcome existing limitations of conventional navigation stereo cameras with small FOV thereby improving marker detection capacity. In results, we demonstrated that FOVs of conventional camera and the Webcam were 885 mm and 1,685 mm, respectively which indicates(More)
Transcranial Magnetic Stimulation (TMS) applying magnetic stimulation directly on neurons of the brain noninvasively is being used to treat stroke, Parkinson's disease, depression, and so on. TMS can provide treatment through more effective stimulation when accurate stimulation is applied to an anatomical position of the patient. So a navigation system for(More)
The growth of industries has led to not only the improvement in quality of life but also increased musculoskeletal diseases due to accumulation of micro-sized damages in muscles or other tissues due to simple and repetitive lifestyle. Similarly, having curvature in the vertebrae is referred to as scoliosis, which is increasingly occurring mostly in(More)
In this study, rehabilitation training in motor skills for hemiplegia patients comprises repetitive and passive contents. To reduce boredom of rehabilitation training and provide active training, a movement-recognizing device and contents using it were manufactured. An accelerometer for detecting movement recognition and EMG sensor signals for detecting(More)
Balance has properties of steadiness, symmetry and dynamic stability and plays an important role in relation to rehabilitation of fallen or hemiparalyzed patients. In this study, degrees of muscle activities of lower limb muscles like tibialis anterior, gastrocnemius, rectus femoris and biceps femoris were analyzed in relation to balance according to(More)
