Objective: To investigate the effect of biofeedback training-assisted treatment on the character of fecal, defecation time and defecation frequency of patients with obstructive constipation. Methods: Ninety patients with obstructive constipation treated in the hospital were selected and divided into three groups by the random number table method. Group A was given conventional treatment, group B was given fixed biofeedback training (FBF) based on conventional treatment, and group C was given adaptive biofeedback training (ABF) based on conventional treatment. The anorectal function, fecal characters, defecation time and defecation frequencies before and after treatment and clinical effects were compared among the three groups. Results: After treatment, the order of anorectal pressure from low to high was as follows: group A, group B, group C (P<0.05). The order of paradoxical contraction rate from high to low was as follows: group A, group B, group C (P<0.05). The anal canal rest pressure and anorectal suppression reflex thresholds of group B and group C were significantly smaller than those of group A (P<0.05), and the anal canal relaxation rate was significantly larger than that in group A (P<0.05). The proportion of type 4~7 fecal character was the highest in group C, followed by group B, and was the lowest in group A (P<0.05). The defecation time of group A was the longest, followed by group B, group C (P<0.05), and the defecation frequency of group A was the least, followed by group B, group C (P<0.05). The total effective rate of group C was significantly higher than that of group A or group B (P<0.05). Conclusion: Biofeedback training, especially ABF, can effectively improve the anorectal function of patients with obstructive constipation. It has obvious advantages in improving fecal character, shortening defecation time and increasing defecation frequency. [ABSTRACT FROM AUTHOR]
