title: The effect of different low-frequency filters on concentric needle jitter in stimulated orbicularis oculi.
abstract: Our objective was to compare the effect of different low-frequency filters on jitter parameters when stimulating the orbicularis oculi.
  
  
  
  Ten healthy volunteers were studied. Jitter was expressed as the mean consecutive difference (MCD). The low filter settings compared were 1, 2, and 3 kHz.
  
  
  
  No significant difference in mean MCD or outliers was found with the different filter settings. No significant difference in mean MCD was seen when the number of potentials analyzed was reduced.
  
  
  
  Different low-frequency settings do not influence the mean MCD when using a peak detection system. Muscle Nerve 54: 317-319, 2016.
