The performance of PDMonitor, an innovative Parkinson's Disease monitoring device developed by PD Neurotechnology, has been evaluated in a multi-site clinical study. The study results have been published in Frontiers in Neurology, a reputable peer-reviewed clinical neurology journal.
The study aimed to determine whether PDMonitor, which utilises wearables and artificial Intelligence (AI) to track and assess symptoms, could provide a reliable and feasible method for informing treatment plans. The device consists of five sensors worn on the patient's trunk and limbs, which gather data on symptom timing and severity. Machine learning algorithms are employed to complete assessments.
The statistical analysis of the study revealed a high level of accuracy in symptom detection, with a strong correlation observed between PDMonitor's automated assessments and expert evaluations of symptom severity. PDMonitor demonstrated accuracy and specificity levels of 99% or more in detecting mild to severe dyskinesia, gait impairment, wrist and leg tremor. Additionally, it achieved at least 96% accuracy in identifying "Off" periods, where Parkinson's symptoms reappear between medication doses.
Another study, also published in Frontiers in Neurology, confirmed the effectiveness and ease of use of PDMonitor for patients and caregivers. It was found that attaching the sensors took an average of just five minutes, even for patients in later stages of the disease. The automatic recording and identification of each sensor's location on the patient's body further enhanced the device's user-friendliness.
These peer-reviewed papers add to the growing body of evidence supporting the accuracy and efficacy of PDMonitor. Preliminary findings from an analysis of data from 267 patients in Greece indicate that continuous telemonitoring in clinical practice can alleviate Parkinson's symptoms. The average "Off" time experienced by patients in the study decreased over two consecutive quarters following the implementation of PDMonitor.
In January 2023, NICE (National Institute for Health and Care Excellence) conditionally recommended PDMonitor, along with three other devices, for remote monitoring of Parkinson's disease to inform treatment. This decision allows for the use of PDMonitor by NHS patients and their physicians in the UK.
While Parkinson's cannot be reversed, careful monitoring and timely intervention can delay symptom deterioration and reduce the risk of falling. Mobility issues, falls, and related fractures remain significant causes of morbidity and hospitalisation in Parkinson's disease. The prudent use of PD Monitor data, which provides a snapshot of patients' home activities, allows for personalised care based on an accurate assessment and a comprehensive "dashboard of vitals" in Parkinson's Disease.
