© 2025 International Parkinson and Movement Disorder Society.Traditional clinical assessments in Parkinson's disease (PD) trials are limited by subjectivity and inter-rater variability. Digital health technologies (DHT) offer an objective continuous assessment of motor symptoms and are increasingly used in clinical research. This review evaluated the role of DHTs as outcome tools in pharmacological trials for PD. A systematic search of MEDLINE and Embase was conducted according to PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, covering studies up to August 31, 2025. Eligible studies included randomized controlled trials, open-label or crossover designs, and observational studies using DHTs to assess motor outcome variables in PD. Studies focusing only on technology development or with fewer than 10 participants were excluded. Data extracted included study design, DHT type, assessment setting, and motor parameters measured. Study quality was appraised using an eight-criterion tool, and level of evidence was rated using the Oxford Centre for Evidence-Based Medicine framework. A total of 42 studies were included, covering 26 distinct DHTs. These comprised 11 wearable sensors and 15 nonwearable systems such as motion capture platforms and force-sensing assessments. DHTs were used to measure bradykinesia, tremor, gait, balance, and nocturnal motor symptoms in both supervised and unsupervised settings. Fifteen studies were rated as high quality, 14 moderate, and 13 low. Among currently available tools, only Opal reached the threshold of Level 1a evidence. Other validated tools included the Parkinson's Kinetigraph, Actiwatch, and Roche PD Mobile Application (Level 1b). DHTs offer valuable tools for objective assessment in PD trials, though broader adoption requires greater standardization and regulatory alignment. © 2025 International Parkinson and Movement Disorder Society.
