Abstract: Objective To investigate the influence of biofeedback and electronic stimulation of pelvic floor combining pelvic floor muscle training on quality of life of elderly women with light or moderate stress urinary incontinence. Methods Sixty elderly female patients suffering from light or moderate stress urinary incontinence were randomly divided into two groups (n=30) and received twelve-week therapy.The test group received biofeedback and electrical stimulation combining pelvic floor muscle training, while the control group received pelvic floor muscle training.They were followed up for three months after the therapy.All the patients received one-hour pad test and the Urinary Incontinence Quality of Life Scale (I-QOL) before and after the therapy and after the follow-up.All the data were statistically analyzed by square-test and T-test.The curative and I-QOL score were compared between the two groups. Results The cure rate of the test group after the therapy and after the follow-up were individually 90.00% (27/30) and 76.67% (23/30);the cure rate of the control group after the therapy and after the follow-up were individually 40.00% (12/30) and 30.00% (9/30).The cure rate of the test group after the therapy and after the follow-up were statistically higher than those of the control group (P <0.05).The mean I-QOL score of the test group before the therapy, after the therapy and after the follow-up were 63.5, 89.6 and 86.4, respectively;the mean I-QOL score of the control group before the therapy, after the therapy and after the follow-up were 64.1, 71.2 and 70.3, respectively.The mean I-QOL score of the test group after therapy and after the follow-up were significantly higher than that before therapy and those of the control group (P < 0.05). Conclusion The biofeedback and electronic stimulation therapy of pelvic floor can evidently alleviate the symptoms of urinary incontinence in elderly women, improve their QOL, and promote their physical and mental health.
