HopkinsPD, new smartphone app developed can help doctors track the severity of Parkinson's disease symptoms.
Parkinson's is a progressive brain disorder and is often tough to treat effectively because symptoms, such as tremors and walking difficulties, can vary dramatically over a period of days, or even hours.
"A smartphone-derived severity score for Parkinson's disease is feasible and provides an objective measure of motor symptoms inside and outside the clinic that could be valuable for clinical care and therapeutic development," said the research team including Srihari Mohan, undergraduate student at the varsity.
The doctor then uses this self-reported or imprecise data to guide treatment.
In the new study, published in the journal JAMA Neurology, the team collected the data with the help of "HopkinsPD" app and then using a machine learning technique, they converted it into an objective Parkinson's disease severity score -- that better reflected the overall severity of patients' symptoms and how well they were responding to medication.
This smartphone evaluation does not rely on the subjective observations of a medical staff, and can be administered any time or day in a clinic or within the patient's home.
The app is available both for Android as well as iOS smartphones.
