操作性肌电生物反馈疗法在康复医学中的应用 总被引:8,自引:3,他引:8
赵文汝 《中国康复医学杂志》2004,19(7):484-485
操作性肌电生物反馈疗法(operant conditioning electromyography biofeedback techniques)是生物反馈疗法中的一种,是涉及物理医学、控制学、生理学、解剖学、心理学及康复医学知识和技术的多学科、综合应用的新技术,在国外是一个独立的边缘学科。它借助肌电接收设备记录自主收缩肌肉时的微弱电信号,并以此为源,通过视觉或听觉通路提供反馈信号。将人们平时不易感知的体内功能变化转变为可以感知的视听信号,并让患者根据这些信号通过指导和自我训练学会控制自身不随意功 相似文献

目的观察表面肌电生物反馈(sEMG-BFB)联合吞咽训练对脑梗死恢复期吞咽障碍患者康复的影响。 方法选取脑梗死恢复期吞咽障碍患者51例,按随机数字表法将其分为常规训练组(26例)和生物反馈组(25例)。常规训练组给予口颜面功能训练、导管球囊扩张术、电刺激及吞咽功能训练等常规康复治疗,生物反馈组在此基础上,将吞咽功能训练改为在sEMG-BFB下进行。训练前、后,采用吞咽造影观察患者食管上段括约肌(UES)的开放情况,并行功能性经口摄食评估(FOIS)。 结果训练前,2组患者FOIS评分、UES开放程度之间比较,差异均无统计学意义(P&rt;0.05)。训练后,2组FOIS评分均较组内训练前有所提高(P<0.05),且生物反馈组训练后FOIS评分[(3.76±1.42)分]高于常规训练组[(2.77±1.42)分](P<0.05)。训练后,常规训练组UES完全开放和不完全开放的例数分别为18例和8例,生物反馈组训练后完全开放和不完全开放的例数分别为20例和5例,与组内训练前比较,差异均有统计学意义(P<0.05)。 结论在常规康复训练的基础上辅以sEMG-BFB治疗,有助于改善脑梗死恢复期吞咽障碍患者UES的开放情况,提高其吞咽功能。 相似文献

OBJECTIVE: To assess device accuracy, patient acceptance, and effect of a computerized biofeedback knee goniometer (CBG), on patients' compliance with active range of motion (AROM) exercises after total knee arthroplasty (TKA). DESIGN: Two-stage study: measurement validation on asymptomatic controls and an unblinded, multiple crossover trial. SETTING: Inpatient rehabilitation. PARTICIPANTS: Asymptomatic controls (n=14) and post-TKA inpatients (n=11). INTERVENTIONS: For measurement validation, CBG-angle measurements were compared with manual, clinician-obtained angles. To assess motivational effect, the CBG was worn after TKA; on alternating days, it either monitored AROM silently (no feedback) or provided audiovisual feedback about reaching preset range of motion (ROM) goals and prompted the patients to exercise when idle. MAIN OUTCOME MEASURES: To assess accuracy, the device's readings were compared with manual measurements. Patient satisfaction was determined by a self-report questionnaire; exercise compliance was assessed by calculating activity rate and stratified interactivity intervals. RESULTS: CBG readings reproduced clinician measurements reliably between 0 degrees and 100 degrees (eta(2)=98.5%). Auditory feedback was more helpful than visual feedback for motivating exercise. During feedback-on days, the mean total activity rate +/- standard deviation was 15.1+/-10.9 activity counts per hour, and the interactivity interval was 6.7+/-5.7 minutes. The activity rate was higher on feedback-off days-22.5+/-11.1 counts/hour (P=.11)-and the mean interactivity interval was 3.6+/-2.7 minutes (P=.07). CONCLUSIONS: The CBG provided reliable, unbiased estimates of clinician measurements of joint angle within the range of 0 degrees to 100 degrees. The CBG was accepted well by most patients. Surprisingly, slightly more ROM activity was noted during feedback-off days than feedback-on days. 相似文献

Objective
To study increases in electromyographic (EMG) response from the right and left rectus femoris muscles of individuals with long-term cervical spinal cord injuries after EMG biofeedback treatment.Design
Repeated measure trials compared EMG responses before and after biofeedback treatment in patients with spinal cord injuries.Main outcome measures
The Neuroeducator was used to analyse and provide feedback of the EMG signal and to measure EMG response.Setting
Department of Traumatic Orthopaedics, School of Medicine, University of São Paulo, Brazil.Participants
Twenty subjects (three men and 17 women), between 21 and 49 years of age, with incomplete spinal cord injury at level C6 or higher (range C2 to C6). Of these subjects, 10 received their spinal cord injuries from motor vehicle accidents, one from a gunshot, five from diving, three from falls and one from spinal disc herniation.Results
Significant differences were found in the EMG response of the right rectus femoris muscle between pre-initial (T1), post-initial (T2) and additional (T3) biofeedback treatment with the subjects in a sitting position [mean (standard deviation) T1: 26 μV (29); T2: 67 μV (50); T3: 77 μV (62)]. The mean differences and 95% confidence intervals for these comparisons were as follows: T1 to T2, −40.7 (−53.1 to −29.4); T2 to T3, −9.6 (−26.1 to 2.3). Similar differences were found for the left leg in a sitting position and for both legs in the sit-to-stand condition.Conclusions
The EMG responses obtained in this study showed that treatment involving EMG biofeedback significantly increased voluntary EMG responses from right and left rectus femoris muscles in individuals with spinal cord injuries. 相似文献13.

Get up and go test in patients with knee osteoarthritis 总被引:2,自引:0,他引:2
Piva SR Fitzgerald GK Irrgang JJ Bouzubar F Starz TW 《Archives of physical medicine and rehabilitation》2004,85(2):284-289
OBJECTIVE: To determine the reliability, minimum detectable change (MDC), and validity of the Get Up and Go (GUG) test. DESIGN: Repeated-measures test-retest for reliability. Correlational study for validity. SETTING: Institutional practice. PARTICIPANTS: Convenience sample of 130 people, 105 with knee osteoarthritis (OA) (80 women; mean age, 62+/-9 y) and 25 healthy controls (21 women; mean age, 57+/-8 y). INTERVENTIONS: Not applicable.Main outcome measures Western Ontario and McMaster Universities Osteoarthritis Index, the Activity of Daily Living Scale of the Knee Outcome Survey, and the 8 scales of the Medical Outcomes Study 36-Item Short-Form Health Survey. RESULTS: Intratester and intertester reliability was.95 (95% confidence interval [CI],.72-.98) and.98 (95% CI,.94-.99), respectively. The MDC, based on measurements by a single tester and between testers, was 1.5 and 1.2 seconds, respectively. Time to perform the GUG test was longer for persons with knee OA than it was for the controls (mean difference, 3.3s; 95% CI, 1.8-4.9). Correlations between the GUG test and measures of physical function did not differ significantly from correlations between the GUG test and measures that do not specifically evaluate physical function. CONCLUSIONS: The GUG test is reliable and has an MDC that is adequate for clinical use. Validity of the GUG test as a single measure of physical function was not supported. Further research should include testing a battery of performance-based measures of physical function. 相似文献
