AI Article Synopsis
- - Researchers explored the use of remote activity monitoring (RAM) with wearable devices as a way to measure physical activity in patients with progressive multiple sclerosis (MS), providing an alternative to physical visits, especially during pandemics or for those living far away.
- - The study involved 56 participants over 2.5 years, using a wearable device to track various physical activity metrics and assessing brain atrophy alongside traditional MS evaluation scales.
- - Results showed that RAM was effective and well-accepted by participants, correlating well with brain atrophy and demonstrating the potential for one-day activity measurements to be as relevant as longer monitoring.
Article Abstract
Background: Clinical outcome measurement in multiple sclerosis (MS) usually requires a physical visit. Remote activity monitoring (RAM) using wearable technology provides a rational alternative, especially desirable when distance is involved or in a pandemic setting.
Objective: To validate RAM in progressive MS using (1) traditional psychometric methods (2) brain atrophy.
Methods: 56 people with progressive MS participated in a longitudinal study over 2.5 years. An arm-worn RAM device measured activity over six days, every six months, and incorporated triaxial accelerometry and transcutaneous physiological variable measurement. Five RAM variables were assessed: physical activity duration, step count, active energy expenditure, metabolic equivalents and a composite RAM score incorporating all four variables. Other assessments every six months included EDSS, MSFC, MSIS-29, Chalder Fatigue Scale and Beck's Depression Inventory. Annualized brain atrophy was measured using SIENA.
Results: RAM was tolerated well by people with MS; the device was worn 99.4% of the time. RAM had good convergent and divergent validity and was responsive, especially with respect to step count. Measurement of physical activity over one day was as responsive as six days. The composite RAM score positively correlated with brain volume loss.
Conclusion: Remote activity monitoring is a valid and acceptable outcome measure in MS.
