Prediction of larynx function using multichannel surface EMG classification.

Total laryngectomy (TL) affects critical functions such as swallowing, coughing and speaking. An artificial, bio-engineered larynx (ABL), operated via myoelectric signals, may improve quality of life for TL patients. To evaluate the efficacy of using surface electromyography (sEMG) as a control signal to predict instances of swallowing, coughing and speaking, sEMG was recorded from submental, intercostal and diaphragm muscles.

An Assistive Coughing Device for Post-Laryngectomy Patients.

People who have undergone total laryngectomy typically have difficulties speaking and coughing. Coughing, the protective reflex action where air is rapidly expelled from the lungs to clear the airway, is crucial in everyday life. Insufficiency in coughing can lead to serious chest infections.

Focus areas of cardiovascular medical device research in South Africa.

We investigated the focus of cardiovascular medical device research in South Africa over the 15-year period 2000 - 2014. Information drawn from journal articles was used for the analysis, with attention to articles describing a contribution to the development of a cardiovascular medical device, or a new application of an existing device. The findings suggest that research has focused on diagnostic and monitoring as well as prosthetic cardiovascular medical devices, with specific emphasis on vascular and valvular heart diseases.
