Biomedical engineers have developed an artificial intelligence (AI)–enhanced pen for personalized handwriting analysis to aid in the early diagnosis of Parkinson’s disease (PD).
In a small pilot study, the “diagnostic pen” accurately recorded handwriting signals, and neural network-assisted analysis successfully distinguished PD from non-PD handwriting with greater than 95% accuracy.
“Further validation through large-scale human studies is necessary to confirm the diagnostic effectiveness of the pen,” first author Guorui (Gary) Chen, PhD candidate, Department of Bioengineering, University of California, Los Angeles, told Medscape Medical News.
“While significant research and development are still required, we are optimistic about its potential for future use in both clinical and home settings,” Chen…
