Variation of electrophysiological ratios calculated for the soleus muscle and passive stiffness of the ankle (mean ± standard deviation) during the 1 Hz and 10 Hz († brackets) stimulation protocols: before (D0) and after (D9: early assessment; D31: late assessment).
| Parameter | D0 | D9 | D31 |
|---|---|---|---|
| H max/M max | 0.75 ± 0.08 | 0.53 ± 0.08* [0.74 ± 0.07]† |
0.49 ± 0.14* [0.75 ± 0.09]† |
| T/M max | 0.49 ± 0.09 | 0.33 ± 0.10* [0.48 ± 0.08]† |
0.33 ± 0.16* [0.47 ± 0.09]† |
| Stiffness index (Nm/rad) | 63.97 ± 21.09 | 61.62 ± 22.73* [63.54 ± 20.71]† |
61.63 ± 22.39* [63.91 ± 21.41]† |
*Statistically significant difference (t-test, P < 0.05). Comparisons were performed between D0 and D9 (significant variations indicated in D9 column) and then between D0 and D31 (significant variations indicated in D31 column). No significant variation was identified between D9 and D31.
