Abstract:
Objective To compare the effects of biofeedback (BF) training on clinical symptoms , psychological status and quality of life in different subtypes of patients with functional defecation disorders (FDD) .Methods According to Rome Ⅲ criteria ,50 FDD patients were divided into non coordinated defecation (F3a) and the lack of promoting defecation (F3b) two subtypes .The patients of these two subtypes received BF training three times every week ,five to ten times each course ,two to three times training at home were required during and after treatment .The changes ,of clinical symptoms scores ,self‐rating anxiety scale (SAS) ,self‐rating depressive scale (SDS) and the patient assessment of constipation quality of life question naire (PAC‐QOL ) were compared between before and after BF training in the patients of two subtypes .The difference between two subtypes were also analyzed as well .Paired t‐test or Wilcoxon signed‐rank test was performed for comparison between before and after treatment ,and group t‐test or Wilcoxon rank sum test was for comparison between groups .Results Among 50 FDD patients , there were 13 cases of F3a type and 37 cases of F3b type .After BF training ,the clinical symptoms scores of two subtypes patients were both lower than those before BF training (5 .62 ± 3 .91 vs 8 .77 ± 3 .59 , 5 .89 ± 3 .67 vs 9 .35 ± 3 .22 ,t = 3 .264 and 6 .272 ,both P< 0 .01) .There were no statistically significant differences in the scores of clinical symptoms between two subtypes at before and after BF training (t =- 0 .545 and - 0 .230 ,both P > 0 .05) .After BF training ,the SAS scores of two subtypes patients were both lower than those before BF training (30 .85 ± 6 .67 vs 42 .46 ± 8 .37 ,30 .65 ± 7 .51 vs 38 .59 ± 8 .38 , t= 4 .536 and 6 .402 ,both P< 0 .01) ,and the scores of SDS were both lower than those before BF training (42 .85 ± 8 .30 vs 53 .92 ± 7 .98 ,43 .95 ± 12 .17 vs 55 .39 ± 10 .83 ,t = 4 .788 and 6 .830 ,both P< 0 .01) . There were no statistically significant differences in the scores of SAS and SDS between two subtypes at before and after BF training (t= 1 .431 ,0 .084 ,- 0 .447 and - 0 .301 ,all P> 0 .05) .After BF training ,the PAC‐QOL scores of two subtypes [0 .54 (0 .15 ,0 .88) 、0 .98 (0 .51 ,1 .34)] were both lower than those before BF training [2 .08(1 .18 ,2 .34) 、1 .86(1 .34 ,2 .29)] ,Z= - 2 .903 、- 4 .825 ,both P < 0 .01) .There were no statistically significant differences in the PAC‐QOL scores between two subtypes at before and after BF training (Z= 0 .409 ,1 .891 ,both P > 0 .05) .Conclusions BF training is both effective on two subtypes of FDD ,which can improve clinical symptoms ,psychological status and quality of life ,and with There is no difference in efficacy between the two subtypes .
