title: [Analysis of influencing factors on rehabilitation effects for 1 422 preschool deaf children following cochlear implantation].
abstract: OBJECTIVE
  To investigate the basic factors of the progress amplitude of hearing and speech rehabilitation effect of preschool deaf children with cochlear implants, and provide guidance for the improvement and optimization of rehabilitation strategies.
  
  
  METHODS
  Using the standard hearing and language assessment tools, tracked and evaluated 1 422 CI preschool deaf children for a period of one year, and calculated the effect of hearing and speech rehabilitation, carried out the correlation analysis and variance analysis among different grouping variables.
  
  
  RESULTS
  (1) There was a negative correlation (P<0.01) between the rehabilitation effect and cochlear implantation age, existed the different degree of positive correlation (P<0.01) between the rehabilitation effect and parents cultural level, but no correlation between the rehabilitation effect and parents hearing status.(2) Father's education level, in comparison to mother's education level, had greater impact on the children rehabilitation effect.(3)There was positive correlation(r=0.689, P<0.01) between the progress amplitude of hearing and speech rehabilitation effect. (4) The progress amplitude of auditory and language rehabilitation effect of 2-3 years old group was the highest value(the progress amplitude of hearing and speech recognition rate reached 77.5%, the progress amplitude of language age progress rate reached 2.02 years old), and there were significant differences (P<0.05) between over 3 years old groups.
  
  
  CONCLUSIONS
  (1) To expect the better progress amplitude of rehabilitation effect, cochlear implant age should not be more than 3 years old. (2) Father's effect in the process of rehabilitation is more helpful for deaf children's learning enthusiasms.
