SNR for each muscle group across time points for (a) MVIC; (b) dynamic and (c) functional tests averaged across eight subjects for Delsys and ESS electrodes. Plus signs represent outliers. The BIC had a lower ESS SNR than the Delsys electrodes for the MVICs (p = 0.007), but the ESS SNR for FCU and TRI were higher for the MVICs than the Delsys electrodes (p < 0.001, p < 0.001). There was no significant difference in SNR for ECR.
