UNLABELLED Bispectral index (BIS) is an electroencephalographic variable promoted for measuring depth of anesthesia. Electromyographic activity influences surface electroencephalography and the calculation of BIS. In this study, we sought to determine the effect of spontaneous electromyographic activity on BIS. BIS was monitored in three volunteers by using an Aspect A-1000 monitor. The experim...

objective: the present study compares the efficacy of two most commonly used biofeedback relaxation techniques in the treatment of generalized anxiety disorder. method: 45 individuals with generalized anxiety disorder were randomly assigned to three groups (n=15): group i received electromyographic biofeedback relaxation training, group ii received alpha-electroencephalographic biofeedback rela...

Background & Aims: This study was performed to compare the effects of open and closed chain terminal knee extension exercises on onset latency of vastus medialis obliques (VMO) and vastus lateralis (VL), pain and function in subjects diagnosed with patellofemoral pain syndrome (PFPS). Methods: In a pretest and posttest 5-week intervention study, 26 subjects diagnosed with PFPS and 13 healthy su...

Background: The time and frequency features of motor unit action potentials (MUAPs) extracted from electromyographic (EMG) signal provide discriminative information for diagnosis and treatment of neuromuscular disorders. However, the results of conventional automatic diagnosis methods using MUAP features is not convincing yet.Objective: The main goal in designing a MUAP characterization system ...

Electromyographic biofeedback is a therapeutic modality used along with other interventions in the treatment of pain. This article presents a brief review of the effectiveness of electromyographic biofeedback in treating musculoskeletal pain. Electromyographic biofeedback may provide pain relief for chronic musculoskeletal pain due to cumulative trauma, and may be proposed as an additional inte...

Gesture recognition, as a core technology of human–computer interaction, has broad application prospects and brings new technical possibilities for smart homes, medical care, sports training, other fields. Compared with the traditional interaction models based on PC use keyboards mice, gesture recognition-based modes can transmit information more naturally, flexibly, intuitively, which become r...

STUDY DESIGN A prospective study in which patients with idiopathic scoliosis were examined longitudinally by radiographic and electromyographic measurements according to a protocol. OBJECTIVES To measure the growth velocity of the spine and the electromyographic ratio of the paraspinal muscles to determine their relation to progression of the scoliotic curve. SUMMARY OF BACKGROUND DATA Seve...

Spasticity has been defined as a motor disorder characterized by a velocity-dependent increase in tonic stretch reflex (muscle tone). Muscle tone consists of mechanical-elastic characteristics, reflex muscle contraction and other elements. The aims of this study were to determine whether to assess spasticity quantitatively, and to characterize biomechanical and electromyographic spasticity asse...
