Table 1 Sensitivity analysis for constant K line for the detection of power-line artifacts

From: High-density surface EMG maps from upper-arm and forearm muscles

k line (2.5) 1 2 3 5 7
Acc 99,74 99,79 99,79 99,74 99,79
S 83,33 83,33 83,33 75,00 75,00
SP 99,83 99,87 99,87 99,87 99,91
P 71,43 76,92 76,92 75,00 81,82
  1. klin e in Eq. 3 was chosen as 2.5 (presented in parenthesis). Increasing values of k line reduced the sensitivity (S) of the threshold thresh line/t , whereas decreasing values decreased the precision (P). Variations in these two indexes affected the Accuracy (Acc) and the Specificity (SP). k line = 2.5 is a good compromise between S and P.
