(Seoul = Yonhap News) Reporter Han Seong-gan = Neupulse, a wrist device developed for the treatment of Tourette’s syndrome, a severe tic disorder in which simple movements and sounds are repeated regardless of one’s intention, has been shown to have significant effects. was found as a result of clinical trials.
Tic disorder, which is common in children between the ages of 8 and 12, usually disappears over time if the symptoms are mild. life gets difficult
Developed by Professor Stephen Jackson, a specialist in Tourette syndrome at the University of Nottingham Medical School in the UK, and Neurotherapeutics, a new company founded by them, the wrist device looks like an Apple Watch or Fitbit smartwatch and can be worn on the wrist. It sends electrical pulses through the median nerve of the peripheral nervous system to the brain, suppressing the brain’s activity that causes tics.
MedicalXpress reported on the 13th that the effectiveness of this wrist device was confirmed through clinical trials.
The research team randomly divided 121 adolescents with moderate to severe tic disorders into three groups.
One group wore a real wrist strap and the other a fake wrist strap for 15 minutes once a day for one month. The other group continued their usual treatment.
In addition, the research team measured the severity and frequency of tics using the Yale Global Tic Severity Scale and the Total Tic Severity Score before and after the clinical trial.
As a result, the group using the real wrist device showed an overall reduction of more than 25% in tic frequency and 35% or more in tic severity after 4 weeks, the research team said.
For each group, the real wrist device group lowered tic severity by an average of 7.1 points (35%). In comparison, the group using the fake wrist device scored an average of 2.13 points lower, and the group that continued the usual treatment only scored 2.11 points lower.
The frequency of ticks per minute also decreased by 15.6 while wearing the real wrist device. While wearing the fake wrist device, it decreased by 7.7 times.
This is a statistically significant difference, the research team explained.
So far, psychological treatment and deep brain stimulation, which stimulates the brain by sending an electric current from the outside through electrodes implanted in the brain, are known to be most effective.
However, most patients do not have easy access to these therapies.
Botox injections, which freeze muscles, are also used to treat Tourette’s syndrome. Botox injections suppress involuntary muscle movement for up to three months, but are not a long-term solution.
The clinical trial results were published on MedRxiv, an Internet site that publishes the contents before being published in medical journals.
