Strength Ratios for Matched-Pairs Analysis.
| Strength Ratio | With Dyskinesis | Without Dyskinesis | Total |
|---|---|---|---|
| UT/LT | 2.791 ± 0.386 | 3.092 ± 0.668 | 2.941 ± 0.556 |
| UT/MT | 2.145 ± 0.333 | 2.423 ± 0.394 | 2.284 ± 0.384 |
| LT/MT | 0.771 ± 0.080 | 0.800 ± 0.117 | 0.785 ± 0.099 |
| SA/UT | 0.503 ± 0.105 | 0.461 ± 0.055 | 0.482 ± 0.085 |
| SA/MT | 1.059 ± 0.162 | 1.106 ± 0.158 | 1.082 ± 0.159 |
| SA/LT | 1.383 ± 0.229 | 1.403 ± 0.237 | 1.393 ± 0.228 |
| LR/MR | 0.676 ± 0.097 | 0.675 ± 0.118 | 0.675 ± 0.106 |
Strength Ratios (M ± SD) were calculated by dividing the averaged peak force of one muscle by the other, respectively. UT = upper trapezius, MT = middle trapezius, LT = lower trapezius, SA = serratus anterior, LR = lateral rotators, and MR = medial rotators. No significant differences were revealed between groups for any of the strength ratios.
