The next generation of tools for rehabilitation robotics requires advanced human-robot interfaces able to activate the device as soon as patient's motion intention is raised. This paper investigated the suitability of Support Vector Machine (SVM) classifiers for identification of locomotion intentions from surface electromyography (sEMG) data. A phase-dependent approach, based on foot contact and...
Quantitative evaluation for estimating motor function is a prerequisite for clinical application of rehabilitation robot. The current clinical evaluations, such as Fugl-Meyer assessment, still have some deficiency. The study provided an innovative evaluation method, which contrasted the physiological character of impaired limb with the contralateral upper limb of post stroke hemiplegic patients, and...
The effectiveness of rehabilitation will be increased substantially (e.g. stroke patients) if the patients are able to use a robotic rehabilitation system at home, after having trained on it at the hospital. Due to high cost and complex architecture, most robotic orthoses are limited to use in the hospital. The "active" orthoses that make use of bio-signals for control purposes, are at present...
While society is partly responsible for a feeling of isolation among children with learning disabilities, this isolation is exacerbated by the child's inability to adjust psychosocially. The authors hypothesize that social inclusion will be a natural outcome if technology can restore or assist the ability of basic self-expression and self-growth. One of the most promising methods of expression for...
A summary is presented of the tracking and surface electromyographic (EMG) results obtained using a robotic workstation that was designed and built for use by stroke participants in order to improve voluntary control of their impaired arm. The intervention consisted of eighteen sessions in which five chronic stroke participants performed a range of tracking tasks using their remaining voluntary effort,...
Lumbar muscle activity assessment was useful in evaluating the muscle conditions of low back pain (LBP) patients. Among many assessment methods, surface electromyography (surface EMG) offered a non-invasive and objective alternative for muscle function studies. However there is no benchmark method for interpreting pathological significance of surface EMG. Surface EMG topography is a novel technique...
We developed an interface to the commercial video game Guitar Heroreg III using surface electromyography (EMG) to create a novel training and evaluation device for upperextremity amputees. Rather than pressing the keys with onepsilas fingers as in the normal game, in our modified version a user merely flexes his or her index, middle, or ring finger muscles, and the resulting myoelectric activity is...
