Object : The object of this trial is to establish a method of biofeedback therapy on asthmatic patients.Method : Biofeedback therapy (BFT) was tried on 3 asthmatic patients. The instruments used were Biological Sound Monitor (BSM Tiep) and Respiratory Resistence Meter (RrM : Nihon-koden).We applied 2 kinds of BSM for 30 minutes, one was S-method that amplified the sound volume of wheezing, and another was T-method that generated "P" sound when the wheezing exceeded the threshold. These methods were on auditory sense information. Instructions were set as followed : on S-method, "Weeken your wheezing", and on T-method, "Decrease your "P" sounds numbers each 5 minutes."When RrM was used (10 minutes), there were on informations of sense of sight, and instructions were set as followed : "Decrease your Rr level and keep it low graduation".Results : 1) BSM-S-method; On 2 cases, wheezing were lost, on 1 case it became weeker after BFT.2) BSM-T-method; On 2 cases, the number of "P" sounds decreased, 1 case showed no change.3) Improvement of Rr after BFT of BSM; i) Immediately after, there were hardly any change.ii) 1 minute after, there were significant lower Rr than before BFT.iii) 2 minutes after, there were lower Rr level than 1 minute after.iv) 3 minutes after, these were equal to that of 2 minutes after Rr.4) Rr meter method; i) There was nor emarkable improvement by one-time training.ii) There was significant improvement from the operant level by 51-60 time training.Conclusion : It is expected that biofeedback therapy can be effective for a decrease of Rr level and a symptomatic improvement of asthmatic patients.
