Therapeutic mechanisms hypothesized to underlie improvements in tension headache activity achieved with combined relaxation and electromyographic (EMG) biofeedback therapy were examined. These therapeutic mechanisms included (1) changes in EMG activity in frontal and trapezii muscles, (2) changes in central pain modulation as indexed by the duration of the second exteroceptive silent period (ES...

The purpose of this study is to evaluate the predictive capability of anorectal physiologic tests for unfavorable outcomes prior to the initiation of biofeedback therapy in patients with dyssynergic defecation. We analyzed a total of 80 consecutive patients who received biofeedback therapy for chronic idiopathic functional constipation with dyssynergic defecation. After classifying the patients...

UNLABELLED Fecal incontinence is a challenging condition in that it exerts various psychosocial impacts on daily life. Different treatment modalities have been suggested for fecal incontinence. The present study aimed to evaluate the efficacy of biofeedback therapy in combination with surgery in the management of fecal incontinence. The present randomized controlled trial was performed on 27 wo...

AIMS The aim of the study was to determine if there is a permanent disorder of mucosal blood flow in patients with solitary rectal ulcer syndrome (SRUS) or a disorder related to autonomic gut innervation and physiological function that is reversible concomitant with successful treatment. Rectal mucosal blood flow was used as a validated measure of extrinsic autonomic nerve function. METHODS S...

Operant conditioning of the electroencephalographic rhythm (EEG biofeedback) is argued to be an effective method for treating children with ADHD. This study was designed to evaluate whether this method, compared to methylphenidate, achieves an equally effective outcome. Participants were 39 children aged between 7 12 years. Thirteen children with attention-deficit/hyperactivity disorder (ADHD) ...

OBJECTIVE To define correlations between vulvar vestibulitis syndrome (VVS) and childhood nocturnal enuresis and the effect of biofeedback therapy. STUDY DESIGN Of 104 women diagnosed with VVS, 54 (30 with primary vulvar vestibulitis syndrome [PVVS] and 24 with secondary vulvar vestibulitis syndrome [SVVS], mean age 24.5 years) chose Glazer biofeedback therapy. Information on lower urinary tr...

OBJECTIVE Low heart rate variability (HRV) has been confirmed in heroin users, but the effects of heart-rate-variability-biofeedback in heroin users remain unknown. This study examined (1) correlations between depression and HRV indices; (2) group differences in HRV indices among a heroin-user group, a group with major depressive disorder but no heroin use, and healthy controls; and (3) the eff...

Depression is a common and serious interictal problem in patients with epilepsy. The genesis of depressive disorders is multifactorial. One aetiological aspect focuses on psychosocial factors. It was hypothesized that uncontrollable, unpredictable chronic aversive events (i.e. epileptic seizures) result in cognitive deficits of external control orientation. If this is true, biofeedback training...

BACKGROUND AND PURPOSE This study explores the effect of vibrotactile biofeedback on gait in 20 patients with bilateral vestibular areflexia using observational gait analysis to score individual balance. METHODS A tilt sensor mounted on the head or trunk is used to detect head or body tilt and activates, via a microprocessor, 12 equally distributed vibrators placed around the waist. Two posit...

BACKGROUND Biofeedback is an established non-pharmacologic technique commonly used in the treatment of migraine and tension type headaches. Multiple published studies have suggested that biofeedback is effective in reducing the frequency and severity of headaches, often allowing patients to decrease their dependence on medication. Studies have also suggested that biofeedback may effect a decrea...
