Table 2 Correlations between EMG and SMG data normalized with regards to the maximum values obtained in the MVC from TA

From: Electromyography and sonomyography analysis of the tibialis anterior: a cross sectional study

  Thickness Pennation angle Maximum peak EMG
Pennation angle r = -0.091   
(p = 0.687)   
Maximum peak EMG r = 0.473 r = 0.462  
(p = 0.023) (p = 0.030)  
Area EMG r = 0.025 r = 0.364 r = 0.267
  (p = 0.911) (p = 0.096) (p = 0.197)
  1. MVC: maximal voluntary contraction.
  2. TA: tibialis anterior.
  3. EMG: electromyography.
  4. r = Pearson’s r correlation coefficient.
  5. p = statistical significance.
