Computer scientists, including one of Indian-origin, has developed a new smartphone-based app that uses sensors to generate a score that reliably reflects symptom severity in patients with Parkinson\u2019s disease.Parkinson\u2019s 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.<\/p>\n
The new app called \u201cHopkinsPD\u201d, developed by researchers from the Johns Hopkins University, helped Parkinson\u2019s patients to objectively monitor symptoms in the home and then share data to doctors.<\/p>\n
\u201cA smartphone-derived severity score for Parkinson\u2019s 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,\u201d said the research team including Srihari Mohan, undergraduate student at the varsity.<\/p>\n
Typically, patients with Parkinson\u2019s disease are evaluated by medical specialists during three or four clinic visits annually, and patients are asked to fill out a cumbersome 24-hour \u201cmotor diary\u201d at home to record their mobility, involuntary twisting movements, etc.<\/p>\n
The doctor then uses this self-reported or imprecise data to guide treatment.<\/p>\n
In the new study, published in the journal JAMA Neurology, the team collected the data with the help of \u201cHopkinsPD\u201d app and then using a machine learning technique, they converted it into an objective Parkinson\u2019s disease severity score\u2014that better reflected the overall severity of patients\u2019 symptoms and how well they were responding to medication.<\/p>\n
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\u2019s home.<\/p>\n
The app is available both for Android as well as iOS smartphones.<\/p>\n
