Results The normal s/z ratio was not influenced by the gender and age, andthe s/z values between the pre-and post-rehabilitation had significant difference. The s/z ratio of thorax breathingwas much longer than that of the abdomen breathing.

• 结果 s/z比值不受年龄、性别的影响,且聋儿组康复训练前后s/z比值有着显著性差异,胸式呼吸的s/z比远大于腹式呼吸组。
