生物反馈联合盆底肌锻炼治疗女性压力性尿失禁的临床研究

目的探讨生物反馈电刺激联合盆底肌锻炼治疗女性压力性尿失禁（stress urinary incontinence,SUI）的临床效果。方法48例轻中度女性压力性尿失禁患者,随机分为治疗组（n=26）与对照组（n=22）,治疗组采用生物反馈电刺激治疗,2次/周,共10次,之后盆底肌锻炼20min/d。对照组行盆底生物反馈电刺激治疗。观察两组疗效。结果两组治疗后均较治疗前漏尿量减少,症状改善。结论生物反馈电刺激联合盆底肌锻炼治疗女性轻中度suI安全有效。治疗后如能继续坚持盆底肌锻炼有助于预防尿失禁的复发。     

生物反馈电刺激治疗对产后盆底功能影响的临床分析

目的探讨生物反馈电刺激对产后盆底功能的影响。方法选择在我院住院经阴道分娩的初产妇600例随机分为实验组和对照组,实验组进行生物反馈电刺激治疗及盆底肌锻炼,对照组只进行盆底肌锻炼,一个月后对比两组产妇的阴道平均肌电压,尿失禁发生率和性生活满意度。结果实验组产妇平均肌电压及性生活满意度分别为（25.12±3.7）UV,80%分别高于对照组（24.46±4.6）UV,52%。差异均有统计学意义。实验组尿失禁发生率（1±0.83）次/d,低于对照组（2±0.33）次/d,差异有统计学意义。结论生物反馈电刺激联合盆底肌锻炼在产后盆底功能恢复方面效果显著。     

慢性便秘患者生物反馈疗法的疗效预测因素分析

 目的 探讨慢性便秘(CC)患者生物反馈(BF)疗法的疗效预测因素。方法 对70例CC患者进行BF治疗,治疗前应用焦虑自评量表(SAS)、抑郁自评量表(SDS)、生活质量汉化版简明健康调查量表(SF-36)及生活方式量表进行问卷调查,同时对患者进行肛门直肠测压。治疗前后通过症状积分量表评定患者5项主要症状,以治疗前后症状积分变化作为BF疗效判断指标,对治疗前采集的可能影响BF疗效的因素进行单因素、多因素分析,得出BF疗效的独立预测因素。结果 单因素分析结果显示,BF疗效与生活质量中的“生理职能”维度呈正相关(r=0.256,P=0.031),与SDS评分(r=-0.315,P=0.007)、初始感觉阈值(r=-0.278,P=0.020)呈负相关。多因素分析结果显示,SDS评分(β=-0.263,P=0.033)、初始感觉阈值(β=-0.281,P=0.013)是BF疗效的独立预测因素。结论 存在抑郁倾向、直肠低敏感的CC患者BF疗效较差,采用相应的治疗措施有助于优化BF疗效。     

两类功能性便秘患者行生物反馈治疗的疗效及随访比较

目的比较生物反馈治疗对两类功能性便秘（FC）的临床疗效及随访效果。方法选择2010年1月至2013年1月收治的72例FC患者,其中慢传输型便秘（STC）患者37例、出口梗阻型便秘（OOC）患者35例。所有患者均行生物反馈治疗,比较患者肛管静息压和肛管最大收缩压,并进行为期半年的随访。结果所有患者均完成2周生物反馈治疗,治疗后OOC组的肛管静息压与入院时同组和治疗后STC组相比,差异均无统计学意义;但治疗后OOC组肛管最大收缩压（146.73±24.51）mmHg明显高于入院时同组（112.51±22.5）mmHg及治疗后STC组（108.35±21.29）mmHg,P〈0.05。所有患者均随访半年。随访后OOC组的汉密尔顿焦虑量表（HAMA）评分（8.25±2.27）显著低于入院时同组（11.01±3.14）及随访后STC组（11.43±3.71）,P〈0.05。随访后OCC组的疾病不确定感量表（MUIS）评分（36.45±7.43）显著低于入院时同组（50.45±12.48）及随访后STC组（44.42±9.67）,P〈0.05。但随访后OCC组的Zung抑郁自评量表（SDS）评分与入院时同组及随访后STC组相比差异均无统计学意义。两组患者总体有效率相比,差异无统计学意义;但OOC组患者治愈率（48.57%）明显高于STC组（29.73%）,P〈0.05。结论生物反馈能有效治疗FC,对OOC的疗效更好。     

肠生物反馈对孤立性直肠溃疡综合征患者直肠黏膜血流的影响

目的研究孤立性直肠溃疡综合征(solitary rectal ulcer syndrome,SRUS)患者的直肠黏膜血流变化,并分析肠生物反馈对SRUS患者症状及直肠黏膜血流的影响.方法16例SRUS患者及20例正常对照组,于生物反馈治疗前后分别采用激光多普勒血流计检测16例SRUS患者的直肠黏膜血流量,同时采用标准问卷表分别记录治疗前后症状变化.结果16例中有12例(75%)自觉症状缓解;16例中有5例(31%)结肠镜检查示溃疡愈合;治疗前SRUS患者直肠黏膜血流量明显低于正常对照组(P＜0.01),生物反馈治疗后,治疗组直肠黏膜血流量明显上升(P＜0.01),其中自觉症状缓解者直肠黏膜血流量增加尤为显著(P=0.001).结论肠生物反馈是一种治疗SRUS患者的有效行为疗法,其治疗效果与直肠黏膜血流的增加有关.     

Relative blood volume based biofeedback during haemodialysis

Intra-dialytic hypotension is the most frequently occurring complication during haemodialysis and can lead to serious complications. Devices that continuously and non-invasively monitor relative blood volume (RBV) changes during HD are being advocated as a tool to maintain an adequate volume of the intravascular compartment in order to avoid dialysis hypotension. Nowadays, most manufacturers have incorporated a RBV monitor in their dialysis apparatus and two manufacturers have designed biofeedback devices that control intra-dialytic RBV changes. The goal of RBV based biofeedback systems is to prevent a severe or abrupt decrease in blood volume in order to prevent the development of dialysis hypotension. Biofeedback technologies can diminish the severity and/or frequency of dialysis hypotension. At present, however, a completely symptom-free HD is not a reality. The major reasons for this are patient characteristics such as cardiovascular co-morbidity and high UF rates and a lack of understanding of the relation between RBV changes and blood pressure/cardiovascular stability.     

Long-term efficacy of biofeedback training for fecal incontinence

PURPOSE: Biofeedback therapy in fecal incontinence has been reported to improve continence in more than 70 percent of patients, but most studies have followed patients for less than two years. METHODS: Patients treated by biofeedback training between 1985 and 1986 were given a questionnaire in 1991, as were incontinent patients who had not entered this treatment program. All were asked for the occurrence, frequency, and severity of incontinence events in the past two weeks. Anamnestic and anorectal manometry data from the initial visit were also compared. RESULTS: Eighteen of 24 treated patients and 40 of 71 untreated patients responded. Of those treated by biofeed-back, 78 percent reported episodes of fecal incontinence as compared with 77.5 percent of those not treated by biofeedback. Severity of incontinence, however, was significantly less (P <0.02) in the treatment group (mean number of events, 0.2/day) than in those without treatment (1/day). In biofeedback-treated patients, it was identical with the frequency and severity reported immediately after therapy. No differences were found with respect to initial clinical data and anorectal manometry between both groups. CONCLUSION: Biofeedback training improves continence in patients not only during treatment and within the first two years but also for several years after therapy.Supported by a grant from the Deutsche Forschungsgemeinschaft, En 50/10.Presented in part at the European Gastrointestinal Motility Symposium, Barcelona, Spain, November 19 to 21, 1992.
