A Multi-Modal Remote Monitoring Platform for Frontotemporal Lobar Degeneration (FTLD) Syndromes

The goal of this project is to develop a robust multi-modal platform for remote monitoring of motor symptoms and cognitive function in FTLD syndromes using wearable sensors and mobile health technology to assess speech, motor, and cognitive functions. The solution will be validated in Progressive Supranuclear Palsy (PSP) by collecting longitudinal data from 60 PSP individuals with PSP. Enrollment will take place over a period of 24 months, though each participant will only be followed for 12 months for data collection. The participants will consist of adult volunteers from two leading CurePSP Centers of Care located at the Atypical Parkinsonism Center at Johns Hopkins Hospital in Baltimore, MD and Massachusetts General Hospital (MGH) in Boston, MA.

• PAMSys (Device): Wearable accelerometer and gyroscope for measuring movement
• LEGSys (Device): Wearable accelerometer and gyroscope for measuring movement

Primary outcomes

• Feasibility [12 months]: Feasibility will be defined by the number of participants who complete the 12 month study and who wear their PAMSys pendant sensors at least 16 hours/day for at least 75% of the designated sensor days (7 days per month).

Secondary outcomes

• PSPRS [12 months]: The Progressive Supranuclear Palsy Rating Scale will be administered in-person every 3 months. The PSPRS is a 28 item scale with a total score of 0-100 where lower scores are less affected.
• Cortical Basal ganglia Functional Scale (CBFS) [12 months]: The Cortical Basal ganglia Functional Scale (CBFS) will be performed every 3 months. The CBFS is a 31 item scale, with a total of 124 possible points, where a lower score is less affected.
• PSP Quality of Life scale (PSP QoL) [12 months]: The PSP Quality of Life scale will be performed every 3 months. The PSP-QoL is a 45 item scale, with a possible scale of 0-100 with lower scores less affected.

Sex: All, ages: 40 Years to 89 Years
