Hypothesis
Can raw data from ActiGraph LEAP devices be manipulated for analysis using the GGIR R package?
Conclusion
GGIR can successfully analyze data from LEAP devices after specific data manipulation.
Supporting Evidence
- Accelerometers are commonly used to assess physical activity and sleep levels.
- GGIR is an open-source R package that processes raw accelerometer data.
- The study involved older adults wearing the LEAP device for 7 days.
Takeaway
Researchers figured out how to use a special program to understand how much older adults move and sleep using a device they wore for a week.
Methodology
Pilot data from a NIH-funded study was analyzed using R to manipulate raw data from LEAP devices.
Participant Demographics
Community-dwelling older adults aged 62 to 91, mean age 74.63 years.
