MEND-HD is a longitudinal study evaluating the feasibility of passive monitoring of gait and chorea in patients with HD and the meaningfulness of these outcomes for patients with HD and their care partners/support persons. Participants will take part in four virtual visits with study investigators to answer survey questions on movement and cognition, perform in-home movement assessments, and take part in an interview regarding the meaningfulness of gait and chorea in their daily lives. Participant and care partner interviews will be used for symptom mapping and qualitative data analysis to assess the relevance and impact of the targeted symptoms on the participant's daily life. The study may be extended to 3 years to include yearly visits.

The ActiGraph LEAP has received 510(k) clearance from the US FDA and offers extensive sensor collections, providing continuous digital measures of activity, sleep, mobility, and additional vital signs, including heart rate and variability, oxygen saturation, and skin temperature, in a single fit-for-purpose device.
The Axivity AX6 is a data logger capable of recording raw data from a suite of integrated sensors. It features a state of the art 6-Axis movement sensor measuring linear acceleration and angular velocity at high precision. All sensor locations and Orientations are identical to the AX3 for maximum compatibility. All data is stored in its raw, unaltered format on the embedded flash memory.

RECRUITINGInter-Method Reliability of Total Time in Chorea (Trunk-Worn vs. Wrist-Worn Device)
Total time in chorea is calculated by summing the duration of all bouts of detected chorea throughout each day and then summed across the week (normalized to wear time). The outcome will assess the ability of the wrist-worn device to differentiate between HD and control participants.
Time frame: 1 week
Known Group Validity of Total Time in Chorea (Trunk-Worn Device)
Total time in chorea is calculated by summing the duration of all bouts of detected chorea throughout each day and then summed across the week (normalized to wear time). The outcome will assess the ability of the wrist-worn device to differentiate between HD and control participants.
Time frame: 1 week
Known Group Validity of Total Time in Chorea (Wrist-Worn Device)
Total time in chorea is calculated by summing the duration of all bouts of detected chorea throughout each day and then summed across the week (normalized to wear time). The outcome will assess the ability of the wrist-worn device to differentiate between HD and control participants.
Time frame: 2 weeks
Inter-Method Reliability of Stride Time Variability (Trunk-Worn vs. Wrist-Worn Device)
Stride time variability is defined as the coefficient of variation of stride time, with the median value calculated across all walking bouts lasting at least 10 seconds. The outcome will assess the agreement between trunk-worn and wrist-worn devices among HD and control participants.
