Comparison of the sEMG signals using different handles. The sEMG results reflecting the total work (a–c) or the rate of work (d–f) of intubation are presented. The Wilcoxon signed-rank test or the paired t-test was used depending on the normal distribution conformity of the paired data difference. M1, left middle deltoid; M2, left lateral head of triceps brachii; M3, left biceps brachii; M4, left brachioradialis; M5, left flexor carpi radialis; M6, left abductor pollicis brevis; M7, extensor pollicis longus. Lines indicate data from the same subject. *p < 0.05; **p < 0.01; ***p < 0.001; ****p < 0.0001.
