INTRODUCTION Developing an automated diagnostic and therapeutic instrument for treating swallowing disorders requires procedures able to reliably detect and evaluate a swallow. We tested a two-stage detection procedure based on a combined electromyography/bioimpedance (EMBI) measurement system. EMBI is able to detect swallows and distinguish them from(More)
A neuroprosthetic device for treating swallowing disorders requires an implantable measurement system capable to analysing the timing and quality of the swallowing process in real time. A combined EMG bioimpedance (EMBI) measurement system was developed and is evaluated here. The study was planned and performed as a case-control study. The studies were(More)
The topic of this contribution is iterative learning control of a drop-foot stimulator in which a predefined angle profile during the swing phase is realized. Ineffective dorsiflexion is compensated by feedback-controlled stimulation of the muscle tibialis anterior. The ankle joint measurement is based on changes in the bioimpedance (BI) caused by leg(More)
This contribution describes the design of linear Iterative Learning Control (ILC) in the time-domain for the automatic adaptation of a drop-foot neuroprosthesis for stroke patients. Ineffective dorsi flexion during gait swing phase is compensated by controlled stimulation of the M. tibials anterior. The ankle-joint measurement is based on a new method in(More)
