To evaluate a self-directed home biofeedback treatment system in a group of community dwelling, otherwise healthy women with symptoms of stress, urge, and mixed urinary incontinence (UI).
Fifty-five women, aged 25 to 81 years, participated in the study.
Initial evaluation included a self-reported continence assessment, a 24-hour bladder and fluid habits diary, severity indices for stress and urge UI, and assessment of pelvic floor strength using a pneumatic biofeedback device. Subjects completed a 16-week self-directed program. Assessment and severity index data were self-reported using a continence assessment form, a 24-hour bladder habit and fluid form, and stress and urge incontinence severity indices. Strength level of the trainer, number of digital bands lit on the screen during contraction, number of sessions, and program (starter, intermediate, advanced, or maintenance) were recorded on data sheets.
The treatment system includes an 8-minute educational and motivational video; a journal for education, instructions, and daily documentation forms; and a home biofeedback trainer with pneumatic vaginal sensors that displays the strength of pelvic muscle contraction.
Forty-four women completed the 16-week program. At the end of treatment, 19 (43%) were dry and 16 (36%) reported 50% or more improvement in number of leaks per day, number of voids per day, or both. Women with stress leakage experienced a significant reduction in the number of incontinent episodes per day and the mean severity index of incontinence (P < .001). Participants with urge UI experienced a significant reduction in the mean number of voids per day and mean severity index for UI (P < .001). Younger subjects were more likely to improve when compared with older participants, but no significant differences were found when comparing women who take estrogen with those who do not take estrogen or when comparing those with a history of bladder surgery with those who had no previous surgery.
These data suggest that self-selected healthy women with symptoms of urge, stress, and mixed incontinence can improve their symptoms and lower their severity index with a minimal intervention, comprehensive, self-directed home biofeedback continence system.
评估一种自我指导的家庭生物反馈治疗系统，该系统用于一组居住在社区、无其他健康问题但有压力性、急迫性和混合性尿失禁（UI）症状的女性。
55名年龄在25至81岁之间的女性参与了该研究。
初始评估包括自我报告的尿失禁评估、24小时膀胱和液体习惯日记、压力性和急迫性尿失禁的严重程度指数，以及使用气动生物反馈设备评估盆底肌肉力量。受试者完成了一个为期16周的自我指导项目。评估和严重程度指数数据通过尿失禁评估表、24小时膀胱习惯和液体表以及压力性和急迫性尿失禁严重程度指数进行自我报告。训练器的强度水平、收缩期间屏幕上亮起的数字带数量、训练次数以及项目（入门、中级、高级或维持）记录在数据表上。
治疗系统包括一个8分钟的教育和激励视频；一本用于教育、指导和日常记录表格的日志；以及一个带有气动阴道传感器的家庭生物反馈训练器，该训练器可显示盆底肌肉收缩的强度。
44名女性完成了为期16周的项目。治疗结束时，19名（43%）女性不再有尿失禁，16名（36%）女性报告每天漏尿次数、每天排尿次数或两者均有50%或更多的改善。有压力性漏尿的女性每天尿失禁发作次数和尿失禁平均严重程度指数显著降低（P < .001）。有急迫性尿失禁的参与者每天平均排尿次数和尿失禁平均严重程度指数显著降低（P < .001）。与老年参与者相比，年轻受试者更有可能改善，但在比较服用雌激素的女性与未服用雌激素的女性时，以及在比较有膀胱手术史的女性与无既往手术史的女性时，未发现显著差异。
这些数据表明，自我选择的有急迫性、压力性和混合性尿失禁症状的健康女性，通过一种最少干预、全面、自我指导的家庭生物反馈尿失禁系统，可以改善症状并降低严重程度指数。
