Article Title: Agreement of Step-Based Metrics From ActiGraph and ActivPAL Accelerometers Worn Concurrently Among Older Adults

doi: 10.1123/jmpb.2022-0001

Figure Lengend Snippet: Histograms and Bland–Altman plots comparing mean daily step counts (a and b), peak 1-min cadence (c and d), and peak 30-min cadence (e and f) for metrics derived using data from concurrently worn AP and AGN. For the histograms (a, c, and e), the darker blue shade (darker black shade in printed versions) represents overlap in distributions and dashed lines represent the arithmetic mean of each distribution from both devices. For Bland–Altman plots (b, d, and f), dashed black lines represent the arithmetic mean of the step-based metric measured by the AP. The middle blue line represents the predicted difference (AG – AP) and 95% LOA were calculated as predicted difference ±1.96 times the SD. LOA = limits of agreement; AP = activPAL3 micro accelerometer; AGN = ActiGraph GT3X+ with data processed using the normal filter; AG = ActiGraph GT3X+ accelerometer.

Article Snippet: Our study evaluated the agreement of mean daily step counts, peak 1-min cadence, and peak 30-min cadence between the hip-worn ActiGraph GT3X+ accelerometer, using the normal filter (AG N ) and the low frequency extension (AG LFE ), and the thigh-worn activPAL3 micro (AP) accelerometer among older adults.
