A visual comparison of the validity maps for bias in the estimated EE and MET. Estimates from both the devices in comparison to the Cosmed for the spectrum of activities performed in Healthy, iSCI and stroke groups. (a,c) Validity map for estimates from ActiGraph wG3TX-BT’s located at waist, ankle and upper arm on the right side (using ActiLife’s SPA), (b,d) Validity map for estimates from Matria-IH1 located at back side of the left upper arm (using Metria-IH1’s Senseware platform SPA). The effect of sensor location on the outcome estimates (EE, MET and step count) when using SPAs for the population with stroke and iSCI from our sample is visually summarized in the map
