AB  - In an electromyographic and muscle force (EMG-Force) model, the variability and 
      uncertainty of the input muscle parameters increase the difficulty of assessing 
      this type of model. In this study, a Monte Carlo method is used to evaluate the 
      robustness and the sensitivity of an EMG-Force model, recently developed by our 
      team, for two groups of simulations (constant and sinusoidal force contractions). 
      Two existing criteria (EMG/force and force/force-variability relations) and a new 
      criterion derived from this model (Root Mean Square error, Error(RMS), between 
      the force command and the generated force) are used to extract relevant 
      simulations and obtain the optimized parameter ranges in constant force 
      contractions, while only the new criterion could be valuable in sinusoidal force 
      contractions. The comparison of obtained results from the two groups of 
      simulations has shown that the new criterion can replace the two existing 
      criteria in constant and sinusoidal force contractions to give rise to stable 
      optimized input parameter ranges for the studied EMG-Force model.
