Parkinson’s disease is a brain illness. It affects more than 10 million people around the world. The illness causes shaking, tight muscles, slow movement, and problems with walking.
There is no cure for Parkinson’s. However, finding it early helps people get care faster. Right now, most doctors look for signs like shaking or slow movement. However, these methods are not always correct. Other tests, such as brain scans, need expensive tools and skilled doctors.
Now, a team from UCLA has made a special 3D pen. The pen has a soft rubber end with small magnets(磁铁) inside. Then the team adds a special ink to it that reacts to the magnets. When people write or draw, the pen sends signals based on how the hand moves. A phone app then reads these signals.
In the study, sixteen people took part. Three of them had Parkinson’s. The researchers asked them to draw different shapes, or write letters on surfaces or in the air. Then, they used a computer program to study the signals. After training the program, one model could tell who had Parkinson’s with 96% accuracy.
Experts say the idea is interesting but needs more testing. Parkinson’s affects more than just handwriting. Still, the pen might help doctors find the disease earlier. Becky Jones from Parkinson’s UK said, “The study is small, but it shows a new way to check Parkinson’s by looking at handwriting changes. These changes can be an early sign. ” Jun Chen, a researcher, added, “The pen is not expensive and easy to use in countries with less money. ”

A. They need a kind of ink to work.
