He takes an example of one case he had of a patient with ringing in his ears who took medication for a month to no effect. Chen's diagnosis was that a spinal disc was protruding and pressing down on the blood vessel. After three "adjustment" sessions, the ringing in the ears was gone.
他舉例說，一位病患耳鳴了一個月，吃了一個月的藥，經過他診斷，原來是椎間盤突出壓迫到神經和血管，矯正三次後，就不再耳鳴。
