Weak myoelectrical signals have been detected in the limbs of people suffering from partial paralysis following a stroke or due to some other medical condition.  These signals can be stimulated to assist voluntary movement as part of what is called integrated volitional control electrical stimulation (IVES) therapy, a rehabilitation technique.  This approach conventionally takes a lot of time for the patient to get used to the movements and the equipment itself is often bulky and unwieldy.  There is a sense of stoic resolve about the current approach to IVES therapy – the patient feels ‘wired-up’ with cables and electrodes – the existing technology is crying out for a transition towards a more hopeful, positive approach.  The aim of this project was to create a device that the patient could attach and remove themselves – even with partial paralysis on one side of their body – an innovative wearable technology that could be mostly be covered by a shirt sleeve.  At o-lab we were dedicated to making the controls as simple as possible, so that daily rehabilitation sessions would become so much less of a chore.  We wanted our device to feel like a lifestyle product, in line with the core technology pioneered by Professor Yoshihiro Muraoka at Waseda University.  We were able to make great leaps in usability, thanks to innovations such as the use of a magnetic sheet consisting of ‘one touch’ contact electrodes, so that the wearer did not have to worry about where the electrodes were contacting the body.


The name WILMO is inspired by what we saw in the patients – people so motivated and driven to get through their rehabilitation sessions every day, knowing that one day through their efforts they would be able to move their limbs again.  We thought WILMO was a brighter, more optimistic name than some of the make-and-model-number naming protocols that make other medical devices sound so sterile. At o-lab we hope WILMO is a part of a new age in innovative rehabilitation technologies.
