肌电生物反馈对躯体形式障碍的心理与生理指标的影响

目的:探讨肌电生物反馈对躯体形式障碍患者的生理和心理指标的影响。方法:将160例患者随机分为2组,在药物治疗的基础上,1组加生物反馈治疗,1组加模拟生物反馈治疗,治疗每天1次,治疗4周。采用症状自评量表(SCL-90)评定疗效,每次生物反馈治疗前后测额肌电值、心率、血压,以观察患者生理指标的变化。结果:(1)SCL-90评分,2组比较治疗4周末各因子分均较治疗前有显著下降(P<0.05);(2)额肌电值:入组时2组患者无显著性差异(P<0.05),治疗后2组患者肌电值差异具有统计学差异(P<0.01)。结论:肌电生物反馈治疗躯体形式障碍起效快,可迅速缓解焦虑症状。     

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.     

车前番泻颗粒联合生物反馈治疗出口梗阻型便秘疗效评价

目的:评价车前番泻颗粒联合生物反馈(BF)治疗出口梗阻型便秘(OCC)的疗效。方法:66例OCC患者BF治疗一个疗程后比较治疗前后直肠压力变化,按患者意愿分为继续BF治疗组和车前番泻颗粒联合治疗组,分组治疗2月后比较2组患者临床症状改善状况。结果:BF治疗前后比较患者直肠静息压、力排结果和直肠最大耐受量显著提高(P<0.05),肛管静息压、肛门直肠缩榨压、直肠初始感觉、初始欲望、强烈欲望均无改变(P>0.05);治疗2月后,BF组和联合组患者较治疗前症状均有显著改善,且联合组优于BF组(P<0.05)。结论:BF联合车前番泻颗粒治疗方案改善患者临床症状优于单独BF治疗,是OCC的有效治疗方案。     

电刺激联合生物反馈疗法对不同分娩方式产妇产后盆底肌康复疗效观察

目的:观察经盆底电刺激联合生物反馈疗法对不同分娩方式产妇盆底肌力康复的临床效果。方法:选择2006年12月～2008年6月足月分娩产后42天复查的110例产妇分为剖宫产组(53例)和阴道分娩组(57例),均给予个体化的电刺激及生物反馈治疗,治疗前后进行盆底肌肉压力检测,评价分析两组的治疗效果。结果:阴道分娩产妇产后6周的阴道静息压、盆底收缩压及Ⅱ类肌纤维的快速收缩压均明显低于剖宫产者(P<0.05)。经盆底康复治疗后,两组的静息压、盆底肌力及Ⅰ、Ⅱ类肌纤维收缩强度、Ⅰ类持续时间及Ⅱ类收缩个数均较治疗前显著提高,但阴道分娩组的阴道静息压仍低于剖宫产组(P<0.01),其他检测指标两组间差异均无统计学意义(P>0.05)。结论:阴道分娩产妇产后6周的阴道张力及盆底肌力低于剖宫产者;不同分娩方式的产妇经电刺激联合生物反馈治疗后盆底肌功能均能得到康复。     

磁刺激联合生物反馈治疗盆底功能障碍性疾病的前瞻性非随机对照研究

目的评价磁刺激联合生物反馈治疗盆底功能障碍性疾病（PFD）的临床疗效,观察其对盆底表面肌电的影响,为提高PFD疗效提供依据。 方法以2021.1-01至2022-06南京中医药大学第二附属医院确诊为PFD并治疗的患者作为研究对象,按患者意愿分为生物反馈组和磁刺激联合生物反馈组,比较治疗后2组的起效时间、临床症状评分、有效率、盆底肌电数值。 结果共134例患者纳入本研究,观察组73例,对照组61例,观察组和对照组起效时的治疗频次分别为3次和8次左右,有效率分别为93.15%和65.57%,观察组临床症状评分改善程度大于对照组,观察组盆底肌力的提高明显优于对照组,差异均有统计学意义。 结论磁刺激联合生物反馈可以缩短盆底康复治疗的起效时间、明显改善PFD的症状、明显提高盆底肌的肌力和耐力,可做为中重度PFD的首选治疗措施。但由于本研究观察的病例数较少、随访时间较短,尚需进行多中心对照实验研究,以确定其价值。     

Pharmacological and behavioral treatment of pediatric migraine and tension-type headache

The problem concerning the treatment of pediatric headache has been the object of several recent reports. Some of the same medications used to treat adult headache problems are also utilized with children but usually at smaller dosages and in different combinations. The recent application of behavioral approaches, in particular biofeedback, for treatment of children’s headaches has been an effective alternative to drugs without the problematic and dangerous side effects of pharmacological treatments. The purpose of this review is to give some indications about the most common pharmacological therapies for migraine and tension-type headache in children, and also to discuss the use of behavioral therapies, in particular biofeedback, as excellent alternatives to drugs.     

Vergence can be controlled by audio feedback,and induces downward ocular deviation

We measured horizontal and vertical eye positions, using binocular search coils, in three humans. Subjects could maintain vergence by means of audio biofeedback. Feedback consisted of a pair of audio tones, one variable and one fixed at a reference frequency. The variable tone was controlled by instantaneous vergence and provided immediate feedback on the vergence state. The reference frequency, which they attempted to match, was set to correspond to a target distance of either 0.34 m or 0.14 m. Subjects could maintain vergence consistently, even while undergoing lateral motions at 0.5 Hz and 0.2 g peak acceleration in darkness. There was also a consistent tendency for the eyes to deviate downward during near vergence. The results may be useful in experiments in which one wishes to control vergence without providing a visual reference which might inhibit conjugate eye movements.
