A new film following the life of Tourette’s campaigner John Davidson MBE is hitting screens this week and it features University of Nottingham research into the development of a wrist device that delivers electrical pulses to control tics.
‘I Swear’, which features Maxine Peake and Robert Aramayo in the leading roles, details John’s troubled teenage and early adult years growing up in the 1980s in Galashiels, a time when very little was known about the condition.
In 2022 John took part in clinical trials of a wrist device developed by the University of Nottingham to control tics and this is played out in a scene in the film, showing Barbara Morera Maiquez, who was a researcher in the School of Psychology carrying out the trial in the lab.
The trial was part of research in 2022 by scientists from the University of Nottingham’s School of Psychology and School of Medicinewho used repetitive trains of electrical stimulation to the median nerve (MNS) at the wrist to entrain rhythmic electrical brain activity - known as brain oscillations - associated with the suppression of movements. They found that rhythmic MNS substantially reduces tic frequency and tic intensity, and removes the urge-to-tic, in individuals with TS.
In his book John described the moment he tried the device:
“The feeling was instant. Wow. Oh my God. This is amazing!
“Those were my first thoughts when I put the band on. Everything felt ... just right. The world felt different. My mind quietened down. I stopped scanning my environment. I could think clearly. I started laughing, then giggling like a wee kid.
'What is it?' Barbara said. 'You have no idea.' My cheeks were aching. I was grinning that hard. 'Oh man, honestly, this feels amazing! And I was so carried away with just how amazing it felt, I didn't even notice that ten minutes had passed, and I hadn't ticced, not even once" – taken from p.285. I Swear: My Life With Tourette's. John Davidson, MBE.
The research is now being used by spin-out company Neupulse to develop a wrist device to be used in the home to control tics, with a product launch anticipated for next year.
It’s amazing to have our work featured in a major film like this, especially as it shines a light on the struggles people with Tourette’s face on a daily basis. We hope that our device along with better diagnosis, further research and better understanding of Tourette’s can help improve the lives of people living with the condition.
As well as the wrist device, the University also has experts from the School of Medicine and Institute of Mental Health leading the National Steering Group for Tourette’s Syndrome and Tics. They have recently published research with coauthors including members of the cast of the film and from Tourettes Action highlighting the lack of available care throughout the country and the difficulties people face in accessing healthcare for tics. Their recently published policy brief calls services to provide equal access to healthcare for people with TS.
The film is out in cinemas on Friday 10 October - Image and trailer courtesy of STUDIOCANAL.
