EMG biofeedback

Miguel A Simón, Ana M Bueno
AIM OF THE STUDY: The aim of this study was to evaluate the efficacy of biofeedback therapy in the treatment of dyssynergic defecation in chronically constipated community-dwelling elderly women. MATERIALS AND METHODS: After an initial assessment phase carried out during 1 month, 20 chronically constipated women with dyssynergic defecation were randomly assigned to either electromyographic biofeedback (EMG-BF) group (n=10) or control group (n=10). Outcome measures used to evaluate the efficacy of treatment were weekly stool frequency, sensation of incomplete evacuation, difficulty evacuation level, mean EMG-activity (μV) of the external anal sphincter during straining to defecate and Anismus index...

BACKGROUND: Due to the absence of agreement about an effective unified treatment for temporomandibular disorders, non-invasive therapies such as EMG-biofeedback generate a greater interest. Furthermore, most studies to the present show methodological deficiencies that must be solved in the future, which makes important to emphasize this line of studies. MATERIAL AND METHODS: Fourteen patients were selected for this case series study, and replied to a questionnaire concerning awareness of bruxism, painful muscles, and muscle tension...

AIMS: The overactive bladder syndrome (OAB) is defined as urinary urgency, usually accompanied by frequency and nocturia, with or without urgency urinary incontinence. Biofeedback-assisted pelvic muscle therapy (BAPFMT) is a first-line treatment option for OAB. The aims of this study were to determine the efficacy and effectiveness of BAPFMT on symptoms of OAB after 9 weeks of treatment and to detect changes EMG activity of individual pelvic floor muscles (PFM) with the MAPLe. METHODS: Patients were randomly divided into an intervention group that received BAPFMT with the MAPLe or into a control group which received only toilet behavior and lifestyle instructions...

Users of myoelectric prostheses can often find them difficult to control. This can lead to passive-use of the device or total rejection, which can have detrimental effects on the contralateral limb due to overuse. Current clinically available prostheses are "open loop" systems, and although considerable effort has been focused on developing biofeedback to "close the loop," there is evidence from laboratory-based studies that other factors, notably improving predictability of response, may be as, if not more, important...

Fecal incontinence is defined by the unintentional loss of solid or liquid stool, and anal incontinence includes leakage of gas and / or fecal incontinence. Anal-fecal incontinence is not a diagnosis but a symptom. Many patients hide the problem from their families, friends, and even their doctors. Epidemiologic studies indicate a prevalence between 7-15 %, up to 30 % in hospitals and up to 70 % in longterm care settings. Anal-fecal incontinence causes a significant socio-economic burden. There is no widely accepted approach for classifying anal-fecal incontinence available...

In Dysfunctional Voiding (DV), the patient contracts the external urethral sphincter or pelvic diaphragm (consisting of striated muscle) during voiding, contrary to normal physiological mechanism. In Flowmetry plus pelvic Electromyography (EMG), the perineal surface electrodes will show a persistent activity during voiding. The cause is believed to be the persistence of an immature bladder control. The overall prevalence of DV is estimated between 7 and 11% of girls of school age. Symptoms of DV comprises a range of symptoms, deriving from outlet obstruction, incomplete voiding and elevated Post Micturition Residual (PMR): from daytime urine leaks, nocturnal enuresis, Urinary Tract Infections (UTI), or Vesicoureteral reflux (VUR), to the final decompensation of upper urinary tract in extreme cases...

Diagnosis of Adult Idiopathic Toe Walking (AITW) is very rare in clinical practice. High quality studies regarding AITW and its treatment options have not been conducted previously. A 28-year-old male patient complaining of lower leg pain was referred to outpatient rehabilitation clinic. Physical examination revealed a gait abnormality of insufficient heel strike at initial contact. The aetiology was investigated and the patient's walking parameters were assessed using a computerized gait analysis system. The AITW was diagnosed...

BACKGROUND: In 1998 it was postulated by the ICCS that urge syndrome, later termed overactive bladder (OAB), and dysfunctional voiding (DV) might not be separate entities and instead represent transitional stages between each other, and that DV may be the evolutionary end product of OAB. The aim of this study was to determine not only if OAB sometimes transitions into DV but also if the reverse occurs, and, if so, might they indeed be parts of one entity. MATERIALS AND METHODS: To create an objective study of these two conditions, specific "qualifiers" supporting the diagnosis of each condition were introduced: 1) DV included the qualifier of an active EMG during voiding on two studies; 2) OAB included the qualifiers of a short lag time (<2 s) as a surrogate for detrusor overactivity (DO) and a quiet EMG during voiding...

There is a growing body of evidence pointing at several types of motor abnormalities found in attention-deficit/hyperactivity disorder (ADHD). In this article we review findings stemming from different paradigms, and suggest an interweaving approach to the different stages involved in the motor regulation process. We start by reviewing various aspects of motor abnormalities found in ADHD and related brain mechanisms. Then, we classify reported motor impairments associated with ADHD, into four classes of motor stages: Attention to the task, motion preparation, motion execution and motion monitoring...

Recent evidence suggests the minimization of muscular effort rather than of the size of bodily sway may be the primary, nervous system goal when regulating the human, standing posture. Different programs have been proposed for balance training; none however has been focused on the activation of postural muscles during standing. In this study we investigated the possibility of minimizing the activation of the calf muscles during standing through biofeedback. By providing subjects with an audio signal that varied in amplitude and frequency with the amplitude of surface electromyograms (EMG) recorded from different regions of the gastrocnemius and soleus muscles, we expected them to be able to minimize the level of muscle activation during standing without increasing the excursion of the center of pressure (CoP)...

OBJECTIVES: We previously demonstrated that rumination is produced by an unperceived, somatic response to food ingestion, and we developed an original biofeedback technique based on electromyography (EMG)-guided control of abdomino-thoracic muscular activity. Our aim was to demonstrate the superiority of biofeedback vs. placebo for the treatment of rumination. METHODS: Randomized, placebo-controlled trial performed in a referral center. Consecutive patients who fulfilled the Rome III criteria for rumination (18 women, 6 men; 19-79 years age) were selected and all included in the study; 1 patient assigned to placebo withdrew because of an unrelated accident...

A stroke is caused when an artery carrying blood from heart to an area in the brain bursts or a clot obstructs the blood flow to brain thereby preventing delivery of oxygen and nutrients. About half of the stroke survivors are left with some degree of disability. Innovative methodologies for restorative neurorehabilitation are urgently required to reduce long-term disability. The ability of the nervous system to reorganize its structure, function and connections as a response to intrinsic or extrinsic stimuli is called neuroplasticity...

Electromyography (EMG) biofeedback training affords patients a better sense of the different muscle activation patterns involved in the movement of the shoulder girdle. It is important to address scapular kinematics with labourers who have daily routines involving large amounts of lifting at shoulder level or higher. This population is at a heightened risk of developing subacromial impingement syndrome (SAIS). The purpose of this study was to investigate the acute effects of scapular stabilization exercises with EMG biofeedback training on scapular kinematics...

BACKGROUND: Targeted activation of the transversus abdominis (TrA) muscle through the abdominal drawing-in maneuver (ADIM) is a frequently prescribed exercise for the prevention and rehabilitation of low back pain. However, there is still debate over the role the ADIM plays in maintaining a stable spine during movement. Thus, a single cohort pre/post-intervention protocol was used to examine whether 5 min of ADIM training prior to a dynamic movement task alters dynamic spine stability and control...
