title: Analysis of crosstalk in the mechanomyographic signals generated by forearm muscles during different wrist postures.
abstract: BACKGROUND
  In this study, we analyzed the crosstalk in mechanomyographic (MMG) signals generated by the extensor digitorum (ED), extensor carpi ulnaris (ECU), and flexor carpi ulnaris (FCU) muscles of the forearm during wrist flexion (WF) and extension (WE) and radial (RD) and ulnar (UD) deviations.
  
  
  METHODS
  Twenty right-handed men (mean ± SD age=26.7 ± 3.83 years) performed the wrist postures. During each wrist posture, MMG signals were detected using 3 accelerometers. Peak cross-correlations were used to quantify crosstalk.
  
  
  RESULTS
  The level of crosstalk ranged from 1.69 to 64.05%. The wrist postures except the RD did not influence the crosstalk significantly between muscle pairs. However, muscles of the forearm compartments influenced the level of crosstalk for each wrist posture significantly.
  
  
  CONCLUSIONS
  The results may be used to improve our understanding of the mechanics of the forearm muscles during wrist postures.
