I have found cut-points for older females and for children, but little information regarding recognised cut-points for healthy adults. Any help would be appreciated. Thank you.
Hi Aiden J. Chauntry
This work by Lee and Tse may be useful to you - Calibration of wrist-worn ActiWatch 2 and ActiGraph wGT3X for assessment of physical activity in young adults (Gait & Posture) https://www.sciencedirect.com/science/article/abs/pii/S0966636218305952
It may be a good idea, if possible, to calibrate your own cut-points on a portion of your sample. Of course that is dependant on your participant and lab access, but would be a solid move.
My concern would be that the age range you present is very broad, so I suspect a one size fits all set of cut-points does not exist.
Otherwise, you could move into raw metrics, and look at Euclidean Norm Minus One (ENMO), activity gradient, or indeed the raw g outputs.
