Research summary
Electronic assistive technology allows individuals with severe disabilities to control equipment that they would otherwise not be able to access. Whilst Stephen Hawking is an example of someone who uses electronic assistive technology there are a wide range of individuals with different conditions and presentations who rely on this technology for independence and control. These devices are commonly split into Communication Aids - that allow individuals with little or no speech to communicate; and Enivronmental Controls - that provide control of equipment around a person for those unable to physically access it - e.g. phones, computers, doors.
Electromyography (EMG) is a way of detecting the tiny electrical signals produced by muscles. EMG is a long established technology and has clear potential for improving the way that individuals with physical disabilities control assistive technology. To date, however, EMG has not successfully been used as a control method for this group of individuals. Recent advances in EMG technology provide new potential for this technology to be used in this way.
The EMG switch being evaluated uses 'dry' sensors (that do not use gels) and produces an on/off output when it detects muscle activity. In a previous lab testing, we have shown that an EMG switch can be worn on several muscle locations giving repeatable and reliable signals. We have also trialled a prototype with a small group of patient participants as part of the development of the switch.
In this study we aim to evaluate the effectiveness of the EMG switch device with a wider range of patients. We also aim to explore how patient and professional participants use the EMG switch in real life situations. The evaluation will include measuring a number of performance data and interviewing patient and professional participants about their experience of using the switch.
