PURPOSE The efficacy of EMG-biofeedback and low-frequency electrical stimulation for the treatment of anal incontinence has not been proven. Our purpose was to evaluate a novel therapeutic concept, termed triple target treatment, which combines amplitude-modulated medium-frequency stimulation and EMG-biofeedback. METHODS Patients with anal incontinence were randomly assigned to the triple tar...

This article examines the economic and human costs of muscle pain and the role of biofeedback in treating chronic muscle pain. The article reviews the physiology of the musculature and the myofascial mantle and the contributions of physiological dysfunction to pain. The article critiques the relaxation model as an inadequate foundation for biofeedback treatment of pain and calls for more compre...

BACKGROUND Many persons post-stroke continue to have difficulty using their more involved upper extremity and home programs may be poorly adhered to limiting the amount of practice an individual receives. More information on the experience of traditional home program and the acceptability of a novel home intervention was sought. OBJECTIVE To qualitatively describe 1) upper extremity use at ho...

Twenty-four migraine patients were randomly assigned to one of four conditions: (a) self-monitoring of headache activity (waiting list), (b) frontalis EMG biofeedback, (c) digit temperature biofeedback, and (d) digit temperature biofeedback plus Rational-Emotive Therapy (RET). Bidirectional control over the target physiological response was assessed through a reversal design in each session. Fo...

We propose the use of electrical stimulation to generate a new sensorial input to the human body to improve the man-machine interfacing, increasing the communication channels between a robot and the human body. This study focus on the sensation generation for a electromyographic (EMG) prosthetic hand, where the need of “biofeedback” is of vital importance to achieve subconscious control. We use...

The effectiveness of EMG biofeedback training for tension headache has been well established. Previous studies evaluating changes in an average EMG activity score from pre- to posttreatment have not consistently found a relationship between a reduction in average EMG activity and headache improvement at posttreatment. The current study is a preliminary analysis of the utility of EMG variance as...

Mining information from EMG signals to detect complex motion intention has attracted growing research attention, especially for upper-limb prosthetic hand applications. In most of the studies, recordings of forearm muscle activities were used as the signal sources, from which the intention of wrist and hand motions were detected using pattern recognition technology. However, most daily-life upp...

OBJECTIVE To investigate the preliminary effectiveness of surface electromyography (sEMG) biofeedback delivered via interaction with a commercial computer game to improve motor control in chronic stroke survivors. DESIGN Single-blinded, 1-group, repeated-measures design: A1, A2, B, A3 (A, assessment; B, intervention). SETTING Laboratory and participants' homes. PARTICIPANTS A convenience ...

The effect of a specific EMG biofeedback treatment protocol on quantified changes in neuromuscular measures and functional activities was examined among the upper extremities of 22 chronic stroke patients who each received 60 feedback training sessions. These data were compared with changes measured from a Control Group of 9 (no treatment) patients. Those patients receiving feedback training sh...

36 clients with anxiety neurosis were trained to reduce frontalis muscle tension over two phases of ten sessions each. They were assessed on psychological and physiological measures, before, during and after the phases. The data analysis indicated that the clients succeeded in lowering frontalis muscle tension levels during the feedback and no-feedback phases of the training sessions. The inter...
