Accuracy of tensiomyographic markers of muscle fatigue in relation to the criterion measure.
| Variable | AUC (95% Cl) | Sensitivity (%) | Specificity (%) | Youden's index | DE (%) |
|---|---|---|---|---|---|
| Dm (mm) | 0.46 (0.15 – 0.77) | 33.3 | 50.0 | 0.17 | 35.7 |
| Tc (ms) | 0.29 (0.03 – 0.55) | 33.3 | 50.0 | 0.17 | 35.7 |
| V10 (mm·s−1) | 0.71 (0.27 – 1.00) | 33.3 | 50.0 | 0.17 | 35.7 |
| V90 (mm·s−1) | 0.37 (0.10 – 0.65) | 33.3 | 50.0 | 0.17 | 35.7 |
Cl, confidence limits; AUC, area under curve; DE, diagnostic effectiveness; Dm, muscle belly displacement; Tc, contraction time; V10, rate of deformation development until 10% Dm; V90, rate of deformation development until 90% Dm.
