The Earswitch in MND
Assessing the potential for a new communication device in earphones, by investigating the prevalence of voluntary contraction of a small muscle in the ear.
This study (being undertaken by the University of Bath) is collecting preliminary information by questionnaire about whether people living with MND could benefit from a new communication/assistive device located in earphones.
Some existing switches to control electronic communication tools, may be difficult for some people with Motor Neurone Disease to use. A company called Earswitch Ltd, have demonstrated that a small muscle in the ear, called the tensor tympani muscle, can be voluntarily moved and effectively used to control a virtual on-screen keyboard to communicate. This technology may be advantageous to a range of people to enable or improve communication.
However, it is not currently known what proportion of people can voluntarily move this ear muscle and therefore potentially benefit from this technology. As such, this research project conducted by the University of Bath will aim to establish what proportion of the general population as well as those with motor neurone disease can move or control this muscle. This research is being conducted with the aim of developing better technological tools to help people with communication problems.
What does taking part involve?
Taking part will involve completing an online survey which will take around 10 minutes to complete.
The information that you and other participants provide will help us to understand what proportion of a population with MND can voluntarily contract this muscle in your ear and may help to develop technology that would assist individuals with severe neurological disorders to communicate more easily in the future.
