Application of Myoelectric Biofeedback Therapy in Rehabilitation of Pelvic Floor Muscle Dysfunction after Rectal Cancer Surgery
Objective To investigate the effect of myoelectric biofeedback therapy on pelvic floor muscle dysfunction after rectal cancer surgery.Methods Eighty patients with pelvic floor muscle dysfunction after rectal cancer surgery admitted to Weihai Municipal Second Hospital from January 2021 to January 2023 were selected as the research objects, and were divided into a control group and an observation group by random number table method.The control group (n=40) received pelvic floor function training, and the observation group (n=40) received myoelectric biofeedback therapy on the basis of the control group.The pelvic floor function, anorectal function and quality of life of the two groups were compared before and after treatment.Results Before treatment, there was no significant difference in total pelvic floor distress inventory-20 (PFDI-20) scores between the two groups (P>0.05);after 2 months of treatment, the total PFDI-20 score of the observation group was (17.87±5.62) points, which was lower than (33.94±7.36) points of the control group, and the difference was statistically significant (P<0.05).Before treatment, there was no significant difference in the anorectal function scores between the two groups (P>0.05);after 2 months of treatment , the anorectal function score in the observation group was ( 8.62 ± 1.27 ) points , higher than (6.54±2.18) points in the control group, and the difference was statistically significant (P<0.05).Before treatment, there was no significant difference in the total functional assessment cancer therapy-colorectal (FACT-C) scores between the two groups (P>0.05);after 2 months of treatment, the total FACT-C score of the observation group was (152.85±8.16) points, which was higher than (126.14±11.73) points of the control group, and the difference was statistically significant (P<0.05).Conclusion Myoelectric biofeedback therapy can alleviate pelvic floor dysfunction, improve anorectal function and improve quality of life in patients with pelvic floor muscle dysfunction after rectal cancer surgery.
