Sanger TD. Bayesian filtering of myoelectric signals. J Neurophysiol 97: 1839 –1845, 2007. First published December 20, 2006; doi:10.1152/jn.00936.2006. Surface electromyography is used in research, to estimate the activity of muscle, in prosthetic design, to provide a control signal, and in biofeedback, to provide subjects with a visual or auditory indication of muscle contraction. Unfortunate...

OBJECTIVE To validate the device and investigate the effect of this device on symptoms, quality of life, and pelvic floor muscle strength. MATERIAL AND METHOD The device was designed to measure vaginal pressure changes using air-pressure balloon and abdominal wall muscle activities using surface electromyography. To test the accuracy of the device, for vaginal pressure measurement, a Mercury ...

OBJECTIVES The purpose of this paper is to describe the outcome of muscle-building therapy for nasal muscles in cases of nasal valve stenosis or collapse. The present study was performed to investigate the best way to combine transcutaneous and intranasal surface electromyography (sEMG) biofeedback training of muscles involved in nasal valve function with a home exercise program and electric st...

Stroke affects 700,000 Americans per year resulting in the largest cause of long-term disability in the United States. Dropfoot is a common condition associated with residual disabilities of stokes and is characterized as a paralysis or weakness of the dorsiflexor muscles of the foot and ankle. The result is an abnormal gait cycle caused by the dragging of the foot and toes during the swing pha...

Constipation is a common feature of Prader-Willi syndrome. Research exploring the prevalence, cause and treatment options for constipation is limited and lacks objective measurements such as anorectal manometry. We report a case of a 16-year-old lady with Prader-Willi syndrome presenting with rectal pain and constipation for 2 years despite multiple medications and weekly enemas. She also noted...

Background: The use of wearables and mobile phone apps in medicine is gaining attention. Biofeedback has the potential to exploit the recent advances in mobile health (mHealth) for the treatment of headaches. Objectives: The aim of this study was to assess the validity of selected wireless wearable health monitoring sensors (WHMS) for measuring surface electromyography (SEMG) and peripheral ski...

Purpose: The aim of the study was to investigate effect electromyography biofeedback (EMG-BF), which in addition conventional electrophysical therapy (EPT) commonly used symptomatic treatment carpal tunnel syndrome (CTS), on motor parameters such as strength and reaction time functional pain function upper extremity.
 Materials Methods: Patients diagnosed with CTS were divided into two gro...

background: dyssynergic defecation disorder (dd) has recognized as the main factor for chronic functional constipation. this was a debilitating disease effective on diverse aspects of physical, psychological and social functions as well as patients’ quality of life generally. modern studies show positive impact of biofeedback therapy on dyssynergic defecation. this study was evaluated the effic...

Functional disorders of pelvic floor muscles are an important element of the many pathological conditions of the anal and rectal area. The problem is manifested by fecal incontinence, chronic anorectal pain, and chronic constipation, affecting a large heterogenous group of patients. Amongst these patients one may observe young women after vaginal births, patients after proctological operations,...
